First, we used the MGC approach to segment the United States at 30 arc second resolution based on principal component information from environmental covariates (gNATSGO soil properties, WorldClim bioclimatic variables, MODIS biological variables, and physiographic variables) to 20 SOC regions. We then trained separate random forest model ensembles for each of the SOC regions identified using environmental covariates and soil profile measurements from the International Soil Carbon Network (ISCN) and an Alaska soil profile data.

However, recent hydrologic data from arid systems show that soil water potentials at depth fluctuate little over long time periods, suggesting this water may be rarely utilized or replenished. In this study, we examine the distributions of root biomass, soil moisture and nutrient contents to 10-m depths at five semi-arid and arid sites across southwestern USA. We couple these depth distributions with strontium (Sr) isotope data that show deep (>1 m) nutrient uptake is prevalent at four of the five sites. At all of the sites, the highest abundance of one or more of the measured nutrients occurred deep within the soil profile, particularly for P, Ca2+ and Mg2+. Phosphate contents were greater at depth than in the top meter of soil at three of five sites. At Jornada, for example, the 2-3 m depth increment had twice the extractable P as the top meter of soil, despite the highest concentrations of P occurring at the surface. The prevalence of such deep resource pools, and our evidence for cation uptake from them, suggest nutrient uptake as a complementary explanation for the occurrence of deep-rooted plants in arid and semi-arid systems. We propose that hydraulic redistribution of shallow surface water to deep soil layers by roots may be the mechanism through which deep soil nutrients are mobilized and taken up by plants.", "keywords": ["2.

While most research shows that soil inorganic N pools and fluxes return to pre-fire levels within a few years, we wondered if vegetation conversion (ponderosa pine to bunchgrass) following stand-replacing fires might be accompanied by a long-term shift in N cycling processes. Using a 34-year stand-replacing wildfire chronosequence with paired, adjacent unburned patches, we examined the long-term dynamics of net and gross nitrogen (N) transformations. We hypothesized that N availability in burned patches would become more similar to those in unburned patches over time after fire as these areas become re-vegetated. Burned patches had higher net and gross nitrification rates than unburned patches (P < 0.01 for both), and nitrification accounted for a greater proportion of N mineralization in burned patches for both net (P < 0.01) and gross (P < 0.04) N transformation measurements. However, trends with time-after-fire were not observed for any other variables. Our findings contrast with previous work, which suggested that high nitrification rates are a short-term response to disturbance. Furthermore, high nitrification rates at our site were not simply correlated with the presence of herbaceous vegetation. Instead, we suggest that stand-replacing wildfire triggers a shift in N cycling that is maintained for at least three decades by various factors, including a shift from a woody to an herbaceous ecosystem and the presence of fire-deposited charcoal.", "keywords": ["Ecology", "Pinus ponderosa Laws", "Nitrogen", "N mineralization", "04 agricultural and veterinary sciences", "15.

A model of the supply and demand chain of biojet involving farmers, biorefineries, airlines, and policymakers is developed by considering factors that drive the decisions of actors (i.e., decision-makers and stakeholders) in the life cycle stages. Two kinds of feedstock are considered: oil-producing feedstock (i.e., camelina and algae) and lignocellulosic biomass (i.e., corn stover, switchgrass, and short rotation woody crops). By factoring in farmer/feedstock producer and biorefinery profitability requirements and risk attitudes, land availability and suitability, as well as a time delay and technological learning factor, a more realistic estimate of the level of biojet supply and emissions reduction can be developed under different oil price assumptions. Factors that drive biojet GHG emissions and unit production costs from each feedstock are identified and quantified. Overall, this study finds that at likely adoption rates biojet alone would not be sufficient to achieve the aviation emissions reduction target. In 2050, under high oil price scenario assumption, GHG emissions can be reduced to a level ranging from 55 to 92%, with a median value of 74%, compared to the 2005 baseline level.", "keywords": ["Greenhouse Effect", "Energy-Generating Resources", "13.

The concerns have been driven by agricultural and trade models, which project that large-scale corn ethanol production leads to substantial decreases in food exports, increases in food prices, and greater deforestation globally. Over the past decade, the increased use of corn for ethanol has been largely matched by the increased corn harvest attributable mainly to increased yields. U.S. exports of corn, wheat, soybeans, pork, chicken, and beef either increased or remained unchanged. Exports of distillers' dry grains (DDG, a coproduct of ethanol production and a valuable animal feed) increased by more than an order of magnitude to 9 million tonnes in 2010. Increased biofuel production may lead to intensification (higher yields) and extensification (more land) of agricultural activities.

Although greenhouse gas emissions have played a role in shaping the RFS, water implications are less understood. We demonstrate a spatial, life cycle approach to estimate water consumption of transportation fuel scenarios, including a comparison to current water withdrawals and drought incidence by state. The water consumption and land footprint of six scenarios are compared to the RFS, including shale oil, coal-to-liquids, shale gas-to-liquids, corn ethanol, and cellulosic ethanol from switchgrass. The corn scenario is the most water and land intense option and is weighted toward drought-prone states. Fossil options and cellulosic ethanol require significantly less water and are weighted toward less drought-prone states. Coal-to-liquids is an exception, where water consumption is partially weighted toward drought-prone states. Results suggest that there may be considerable water and land impacts associated with meeting energy security goals through using only biofuels. Ultimately, water and land requirements may constrain energy security goals without careful planning, indicating that there is a need to better balance trade-offs.

Nitrogen deposition rates in southern California are the highest in North America and have had substantial effects on ecosystem functioning. We document changes in the belowground C cycle near ponderosa pine trees experiencing experimental nitrogen (N) addition (50 and 150 kg N ha\uffe2\uff88\uff921a\uffe2\uff88\uff921as slow release urea since 1997) at two end\uffe2\uff80\uff90member sites along a pollution gradient in the San Bernardino Mountains, California. Despite considerable differences in N deposition between the two sites, we observed parallel changes in microbial substrate use and soil enzyme activity with N addition. \uffce\uff9414C measurements indicate that the mean age of C respired by the Oa horizon declined 10\uffe2\uff80\uff9315 years with N addition at both sites. N addition caused an increase in cellulolytic enzyme activity at the polluted site and a decrease in ligninolytic enzyme activity at the unpolluted site. Given the likely differences in lignin and cellulose ages, this could explain the difference in the age of microbial respiration with N addition. Measurements of fractionated soil organic matter did not show the same magnitude of changes in response to N addition as were observed for respired C. This lesser response was likely because the soils are mostly composed of C having turnover times of decades to centuries, and 9 years of N amendment were not enough to affect this material. Consequently, \uffce\uff9414C of respired CO2provided a more sensitive indicator of the effects of N addition than other methods. Results suggest that enhanced N deposition alone may not result in increased soil C storage in xeric ecosystems.

An alternative is to grow lignocellulosic (cellulosic) crops on 'marginal' lands. Cellulosic feedstocks can have positive environmental outcomes and could make up a substantial proportion of future energy portfolios. However, the availability of marginal lands for cellulosic feedstock production, and the resulting greenhouse gas (GHG) emissions, remains uncertain. Here we evaluate the potential for marginal lands in ten Midwestern US states to produce sizeable amounts of biomass and concurrently mitigate GHG emissions. In a comparative assessment of six alternative cropping systems over 20 years, we found that successional herbaceous vegetation, once well established, has a direct GHG emissions mitigation capacity that rivals that of purpose-grown crops (-851\u2009\u00b1\u200946 grams of CO(2) equivalent emissions per square metre per year (gCO(2)e\u2009m(-2)\u2009yr(-1))). If fertilized, these communities have the capacity to produce about 63\u2009\u00b1\u20095 gigajoules of ethanol energy per hectare per year. By contrast, an adjacent, no-till corn-soybean-wheat rotation produces on average 41\u2009\u00b1\u20091 gigajoules of biofuel energy per hectare per year and has a net direct mitigation capacity of -397\u2009\u00b1\u200932\u2009gCO(2)e\u2009m(-2)\u2009yr(-1); a continuous corn rotation would probably produce about 62\u2009\u00b1\u20097 gigajoules of biofuel energy per hectare per year, with 13% less mitigation. We also perform quantitative modelling of successional vegetation on marginal lands in the region at a resolution of 0.4 hectares, constrained by the requirement that each modelled location be within 80 kilometres of a potential biorefinery. Our results suggest that such vegetation could produce about 21 gigalitres of ethanol per year from around 11 million hectares, or approximately 25 per cent of the 2022 target for cellulosic biofuel mandated by the US Energy Independence and Security Act of 2007, with no initial carbon debt nor the indirect land-use costs associated with food-based biofuels.

Grazing potentially alters grassland ecosystem carbon (C) and nitrogen (N) storage and cycles, however, the overall direction and magnitude of such alterations are poorly understood on the Northern Great Plains (NGP). By synthesizing data from multiple studies on grazed NGP ecosystems, we quantified the response of 30 variables to C and N pools and fluxes to grazing using a comprehensive meta-analysis method. Results showed that grazing enhanced soil C (5.2\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff894.6% relative) and N (11.3\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff899.1%) pools in the top layer, stimulated litter decomposition (26.8\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff8918.4%) and soil N mineralization (22.3\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff8918.4%) and enhanced soil NH4+(51.5\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff8942.9%) and NO3\uffe2\uff88\uff92(47.5\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff8920.7%) concentrations. Our results indicate that the NGP grasslands have sequestered C and N in the past 70 to 80 years, recovering C and N lost during a period of widespread grassland deterioration that occurred in the first half of the 20thcentury.

Over 13 million ha of former cropland are enrolled in the US Conservation Reserve Program (CRP), providing well-recognized biodiversity, water quality, and carbon (C) sequestration benefits that could be lost on conversion back to agricultural production. Here we provide measurements of the greenhouse gas consequences of converting CRP land to continuous corn, corn\uffe2\uff80\uff93soybean, or perennial grass for biofuel production. No-till soybeans preceded the annual crops and created an initial carbon debt of 10.6 Mg CO 2 equivalents (CO 2 e)\uffc2\uffb7ha \uffe2\uff88\uff921 that included agronomic inputs, changes in C stocks, altered N 2 O and CH 4 fluxes, and foregone C sequestration less a fossil fuel offset credit. Total debt, which includes future debt created by additional changes in soil C stocks and the loss of substantial future soil C sequestration, can be constrained to 68 Mg CO 2 e\uffc2\uffb7ha \uffe2\uff88\uff921 if subsequent crops are under permanent no-till management. If tilled, however, total debt triples to 222 Mg CO 2 e\uffc2\uffb7ha \uffe2\uff88\uff921 on account of further soil C loss. Projected C debt repayment periods under no-till management range from 29 to 40 y for corn\uffe2\uff80\uff93soybean and continuous corn, respectively. Under conventional tillage repayment periods are three times longer, from 89 to 123 y, respectively. Alternatively, the direct use of existing CRP grasslands for cellulosic feedstock production would avoid C debt entirely and provide modest climate change mitigation immediately. Incentives for permanent no till and especially permission to harvest CRP biomass for cellulosic biofuel would help to blunt the climate impact of future CRP conversion.

Biomass-derived energy offers the potential to increase energy security while mitigating anthropogenic climate change, but a successful path toward increased production requires a thorough accounting of costs and benefits. Until recently, the efficacy of biomass-derived energy has focused primarily on biogeochemical consequences. Here we show that the biogeophysical effects that result from hypothetical conversion of annual to perennial bioenergy crops across the central United States impart a significant local to regional cooling with considerable implications for the reservoir of stored soil water. This cooling effect is related mainly to local increases in transpiration, but also to higher albedo. The reduction in radiative forcing from albedo alone is equivalent to a carbon emissions reduction of, which is six times larger than the annual biogeochemical effects that arise from offsetting fossil fuel use. Thus, in the near-term, the biogeophysical effects are an important aspect of climate impacts of biofuels, even at the global scale. Locally, the simulated cooling is sufficiently large to partially offset projected warming due to increasing greenhouse gases over the next few decades. These results demonstrate that a thorough evaluation of costs and benefits of bioenergy-related land-use change must include potential impacts on the surface energy and water balance to comprehensively address important concerns for local, regional, and global climate change.

Grasslands all over the world are undergoing a rapid shift from herbaceous to woody-plant dominance, a phenomenon known as woody-plant encroachment. The impact of this global phenomenon on livestock production (LP), the main ecosystem service provided by grasslands, remains largely unexplored. We quantified, for the first time, the impact of woody-plant encroachment on LP at a large scale, finding a reduction of between 0.6 and 1.6 reproductive cows per square kilometer for each 1% increase in tree cover. By comparing the largest rangelands of the Americas (United States and Argentina), we also showed how the impact of woody-plant encroachment is mediated by social\uffe2\uff80\uff93economic factors. Our paper represents a significant advance in our understanding of grasslands as complex social\uffe2\uff80\uff93ecological systems.

Multiple lines of evidence suggest that plant water-use efficiency (WUE)\uffe2\uff80\uff94the ratio of carbon assimilation to water loss\uffe2\uff80\uff94has increased in recent decades. Although rising atmospheric CO 2 has been proposed as the principal cause, the underlying physiological mechanisms are still being debated, and implications for the global water cycle remain uncertain. Here, we addressed this gap using 30-y tree ring records of carbon and oxygen isotope measurements and basal area increment from 12 species in 8 North American mature temperate forests. Our goal was to separate the contributions of enhanced photosynthesis and reduced stomatal conductance to WUE trends and to assess consistency between multiple commonly used methods for estimating WUE. Our results show that tree ring-derived estimates of increases in WUE are consistent with estimates from atmospheric measurements and predictions based on an optimal balancing of carbon gains and water costs, but are lower than those based on ecosystem-scale flux observations. Although both physiological mechanisms contributed to rising WUE, enhanced photosynthesis was widespread, while reductions in stomatal conductance were modest and restricted to species that experienced moisture limitations. This finding challenges the hypothesis that rising WUE in forests is primarily the result of widespread, CO 2 -induced reductions in stomatal conductance. Diversified crop rotation may improve production efficiency, reduce fertilizer nitrogen (N) requirements for corn (Zea mays L.), and increase soil carbon (C) storage. Objectives were to determine effect of rotation and fertilizer N on soil C sequestration and N use. An experiment was started in 1990 on a Barnes clay loam (U.S. soil taxonomy: fine-loamy, mixed, superactive, frigid Calcic Hapludoll) near Brookings, SD. Tillage systems for corn\uffe2\uff80\uff93soybean (Glycine max [L.] Merr.) rotations were conventional tillage (CS) and ridge tillage (CSr). Rotations under conventional tillage were continuous corn (CC), and a 4-year rotation of corn\uffe2\uff80\uff93soybean\uffe2\uff80\uff93wheat (Triticum aestivum L.) companion-seeded with alfalfa (Medicago sativa L.)\uffe2\uff80\uff93alfalfa hay (CSWA). Additional treatments included plots of perennial warm season, cool season, and mixtures of warm and cool season grasses. N treatments for corn were corn fertilized for a grain yield of 8.5 Mg ha\uffe2\uff80\uff931(highN), of 5.3 Mg ha\uffe2\uff80\uff931(midN), and with no N fertilizer (noN). Total (1990\uffe2\uff80\uff932000) corn grain yield was not different among rotations at 80.8 Mg ha\uffe2\uff80\uff931under highN. Corn yield differences among rotations increased with decreased fertilizer N. Total (1990\uffe2\uff80\uff932000) corn yields with noN fertilizer were 69 Mg ha\uffe2\uff80\uff931under CSWA, 53 Mg ha\uffe2\uff80\uff931under CS, and 35 Mg ha\uffe2\uff80\uff931under CC. Total N attributed to rotations (noN treatments) was 0.68 Mg ha\uffe2\uff80\uff931under CSWA, 0.61 Mg ha\uffe2\uff80\uff931under CS, and 0.28 Mg ha\uffe2\uff80\uff931under CC. Plant carbon return depended on rotation and N. In the past 10 years, total C returned from above- ground biomass was 29.8 Mg ha\uffe2\uff80\uff931under CC with highN, and 12.8 Mg ha\uffe2\uff80\uff931under CSWA with noN. Soil C in the top 15 cm significantly increased (0.7 g kg\uffe2\uff80\uff931) with perennial grass cover, remained unchanged under CSr, and decreased (1.7 g kg\uffe2\uff80\uff931) under CC, CS, and CSWA. C to N ratio significantly narrowed (\uffe2\uff80\uff930.75) with CSWA and widened (0.72) under grass. Diversified rotations have potential to increase N use efficiency and reduce fertilizer N input for corn. However, within a corn production system using conventional tillage and producing (averaged across rotation and N treatment) about 6.2-Mg ha\uffe2\uff80\uff931corn grain per year, we found no gain in soil C after 10 years regardless of rotation.

Mangrove Forests In The Southeastern United States", "description": "Abstract

We live in an era of unprecedented ecological change in which ecologists and natural resource managers are increasingly challenged to anticipate and prepare for the ecological effects of future global change. In this study, we investigated the potential effect of winter climate change upon salt marsh and mangrove forest foundation species in the southeastern United States. Our research addresses the following three questions: (1) What is the relationship between winter climate and the presence and abundance of mangrove forests relative to salt marshes; (2) How vulnerable are salt marshes to winter climate change\uffe2\uff80\uff90induced mangrove forest range expansion; and (3) What is the potential future distribution and relative abundance of mangrove forests under alternative winter climate change scenarios? We developed simple winter climate\uffe2\uff80\uff90based models to predict mangrove forest distribution and relative abundance using observed winter temperature data (1970\uffe2\uff80\uff932000) and mangrove forest and salt marsh habitat data. Our results identify winter climate thresholds for salt marsh\uffe2\uff80\uff93mangrove forest interactions and highlight coastal areas in the southeastern United States (e.g., Texas, Louisiana, and parts of Florida) where relatively small changes in the intensity and frequency of extreme winter events could cause relatively dramatic landscape\uffe2\uff80\uff90scale ecosystem structural and functional change in the form of poleward mangrove forest migration and salt marsh displacement. The ecological implications of these marsh\uffe2\uff80\uff90to\uffe2\uff80\uff90mangrove forest conversions are poorly understood, but would likely include changes for associated fish and wildlife populations and for the supply of some ecosystem goods and services.

Globally, biological invasions can have strong impacts on biodiversity as well as ecosystem functioning. While less conspicuous than introduced aboveground organisms, introduced belowground organisms may have similarly strong effects. Here, we synthesize for the first time the impacts of introduced earthworms on plant diversity and community composition in North American forests. We conducted a meta\uffe2\uff80\uff90analysis using a total of 645 observations to quantify mean effect sizes of associations between introduced earthworm communities and plant diversity, cover of plant functional groups, and cover of native and non\uffe2\uff80\uff90native plants. We found that plant diversity significantly declined with increasing richness of introduced earthworm ecological groups. While plant species richness or evenness did not change with earthworm invasion, our results indicate clear changes in plant community composition: cover of graminoids and non\uffe2\uff80\uff90native plant species significantly increased, and cover of native plant species (of all functional groups) tended to decrease, with increasing earthworm biomass. Overall, these findings support the hypothesis that introduced earthworms facilitate particular plant species adapted to the abiotic conditions of earthworm\uffe2\uff80\uff90invaded forests. Further, our study provides evidence that introduced earthworms are associated with declines in plant diversity in North American forests. Changing plant functional composition in these forests may have long\uffe2\uff80\uff90lasting effects on ecosystem functioning.

Meeting end\uffe2\uff80\uff90of\uffe2\uff80\uff90century global warming targets requires aggressive action on multiple fronts. Recent reports note the futility of addressing mitigation goals without fully engaging the agricultural sector, yet no available assessments combine both nature\uffe2\uff80\uff90based solutions (reforestation, grassland and wetland protection, and agricultural practice change) and cellulosic bioenergy for a single geographic region. Collectively, these solutions might offer a suite of climate, biodiversity, and other benefits greater than either alone. Nature\uffe2\uff80\uff90based solutions are largely constrained by the duration of carbon accrual in soils and forest biomass; each of these carbon pools will eventually saturate. Bioenergy solutions can last indefinitely but carry significant environmental risk if carelessly deployed. We detail a simplified scenario for the United States that illustrates the benefits of combining approaches. We assign a portion of non\uffe2\uff80\uff90forested former cropland to bioenergy sufficient to meet projected mid\uffe2\uff80\uff90century transportation needs, with the remainder assigned to nature\uffe2\uff80\uff90based solutions such as reforestation. Bottom\uffe2\uff80\uff90up mitigation potentials for the aggregate contributions of crop, grazing, forest, and bioenergy lands are assessed by including in a Monte Carlo model conservative ranges for cost\uffe2\uff80\uff90effective local mitigation capacities, together with ranges for (a) areal extents that avoid double counting and include realistic adoption rates and (b) the projected duration of different carbon sinks. The projected duration illustrates the net effect of eventually saturating soil carbon pools in the case of most strategies, and additionally saturating biomass carbon pools in the case of forest management. Results show a conservative end\uffe2\uff80\uff90of\uffe2\uff80\uff90century mitigation capacity of 110 (57\uffe2\uff80\uff93178) Gt CO2e for the U.S., ~50% higher than existing estimates that prioritize nature\uffe2\uff80\uff90based or bioenergy solutions separately. Further research is needed to shrink uncertainties, but there is sufficient confidence in the general magnitude and direction of a combined approach to plan for deployment now.Western United States forest wildfire activity is widely thought to have increased in recent decades, yet neither the extent of recent changes nor the degree to which climate may be driving regional changes in wildfire has been systematically documented. Much of the public and scientific discussion of changes in western United States wildfire has focused instead on the effects of 19th- and 20th-century land-use history. We compiled a comprehensive database of large wildfires in western United States forests since 1970 and compared it with hydroclimatic and land-surface data. Here, we show that large wildfire activity increased suddenly and markedly in the mid-1980s, with higher large-wildfire frequency, longer wildfire durations, and longer wildfire seasons.

Moreover, inoculation of a Bacillus amyloliquefaciens strain QST713-based product on potatoes also changed the abundance of specific taxonomic groups and the structure of local networks in those locations where the product caused an increase in the yield.

To construct con- tinental-scale N budgets, we produced maps of N deposition fluxes from site-network observations for the United States and Western Europe. Increases in the rates of N cycling for these two regions of the world are large, and they have undergone profound modification of biospheric-atmospheric N exchanges, and ecosystem function. The maps are necessarily restricted to the network measured quantities and consist of statistically interpolated fields of aqueous NO3 and NH4, gaseous HNO3 and NO2 (in Europe), and particulate NO3 and NH4. There remain a number of gaps in the budgets, including organic N and NH3 de- position. The interpolated spatially continuous fields allow estimation of regionally inte- grated budget terms. Dry-deposition fluxes were the most problematic because of low station density and uncertainties associated with exchange mechanisms. We estimated dry N de- position fluxes by multiplying interpolated surface-air concentrations for each chemical species by model-calculated, spatially explicit deposition velocities. Deposition of the ox- idized N species, by-products of fossil-fuel combustion, dominate the U.S. N deposition budget with 2.5 Tg of NOy-N out of a total of 3.7-4.5 Tg of N deposited annually onto the conterminous United States. Deposition of the reduced species, which are by-products of farming and animal husbandry, dominate the Western European N-deposition budget with a total of 4.3-6.3 Tg N deposited each year out of a total of 8.4-10.8 Tg N. Western Europe receives five times more N in precipitation than does the conterminous United States. Estimated N emissions exceed measured deposition in the United States by 5.3- 7.81 Tg N, suggesting significant N export or under-sampling of urban influence. In Europe, estimated emissions better balance measured deposition, with an imbalance of between 0.63 and 2.88 Tg N, suggesting that much of the N emitted in Europe is deposited there, with possible N import from the United States. The sampling network in Europe includes urban influences because of the greater population density of Western Europe. Our analysis of N deposition for both regions was limited by sampling density. The framework we present for quantification of patterns of N deposition provides a constraint on our under- standing of continental biospheric-atmospheric N cycles. These spatially explicit wet and dry N fluxes also provide a tool for verifying regional and global models of atmospheric chemistry and transport, and they represent critical inputs into terrestrial models of bio- geochemistry.", "keywords": ["atmospheric chemistry", "N deposition patterns", "Western Europe", "NOx", "15.

River floodplains have the potential to remove nitrate from water through denitrification, the anaerobic microbial conversion of nitrate to nitrogen gas. An important factor in this process is the interaction of river water with floodplain soil; however, many rivers have been disconnected from their historic floodplains by levees. To test the effect of reflooding a degraded floodplain on nitrate removal, we studied changes in soil denitrification rates on the Baraboo River floodplain in Wisconsin, USA, as it underwent restoration. Prior to this study, the site had been leveed, drained, and farmed for more than 50 years. In late fall 2002, the field drainage system was removed, and a gate structure was installed to allow controlled flooding of this site with river water. Soil moisture was extremely variable among zones and months and reflected local weather. Soil organic matter was stable over the study period with differences occurring along the elevation gradient. High soil nitrate concentrations occurred in dry, relatively organic\uffe2\uff80\uff90poor soil samples and, conversely, all samples with high moisture soils characterized by low nitrate. We measured denitrification in static cores and potential denitrification in bulk samples amended with carbon and nitrogen, one year before and two years following the manipulation. Denitrification rates showed high temporal and spatial variability. Static core rates of individual sites ranged widely (from 0.00 to 16.7 \uffce\uffbcg N2O\uffe2\uff80\uff90N\uffc2\uffb7[kg soil]\uffe2\uff88\uff921\uffc2\uffb7h\uffe2\uff88\uff921, mean \uffc2\uffb1 SD = 1.10 \uffc2\uffb1 3.02), and denitrification enzyme activity (DEA) rates were similar with a slightly higher mean (from 0.00 to 15.0 \uffce\uffbcg N2O\uffe2\uff80\uff90N\uffc2\uffb7[kg soil]\uffe2\uff88\uff921\uffc2\uffb7h\uffe2\uff88\uff921, 1.41 \uffc2\uffb1 1.98). Denitrification was not well\uffe2\uff80\uff90correlated with soil nitrate, organic matter content, or moisture levels, the three parameters typically thought to control denitrification. Static core denitrification rates were not significantly different across years, and DEA rates decreased slightly the second year after restoration. These results demonstrate that restored agricultural soil has the potential for denitrification, but that floodplain restoration did not immediately improve this potential. Future floodplain restorations should be designed to test alternative methods of increasing denitrification.

Despite the use of best management practices for nitrogen (N) application rate and timing, significant losses of nitrate nitrogen NO\uffe2\uff88\uff923\uffe2\uff80\uff93N in drainage discharge continue to occur from row crop cropping systems. Our objective was to determine whether a autumn\uffe2\uff80\uff90seeded winter rye (Secale cereale L.) cover crop following corn (Zea mays L.) would reduce NO\uffe2\uff88\uff923\uffe2\uff80\uff93N losses through subsurface tile drainage in a corn\uffe2\uff80\uff93soybean [Glycine max (L.) Merr.] cropping system in the northern Corn Belt (USA) in a moderately well\uffe2\uff80\uff90drained soil. Both phases of the corn\uffe2\uff80\uff93soybean rotation, with and without the winter rye cover crop following corn, were established in 1998 in a Normania clay loam (fine\uffe2\uff80\uff90loamy, mixed, mesic Aquic Haplustoll) soil at Lamberton, MN. Cover cropping did not affect subsequent soybean yield, but reduced drainage discharge, flow\uffe2\uff80\uff90weighted mean nitrate concentration (FWMNC), and NO\uffe2\uff88\uff923\uffe2\uff80\uff93N loss relative to winter fallow, although the magnitude of the effect varied considerably with annual precipitation. Three\uffe2\uff80\uff90year average drainage discharge was lower with a winter rye cover crop than without (p = 0.06). Over three years, subsurface tile\uffe2\uff80\uff90drainage discharge was reduced 11% and NO\uffe2\uff88\uff923\uffe2\uff80\uff93N loss was reduced 13% for a corn\uffe2\uff80\uff93soybean cropping system with a rye cover crop following corn than with no rye cover crop. We estimate that establishment of a winter rye cover crop after corn will be successful in one of four years in southwestern Minnesota. Cover cropping with rye has the potential to be an effective management tool for reducing NO\uffe2\uff88\uff923\uffe2\uff80\uff93N loss from subsurface drainage discharge despite challenges to establishment and spring growth in the north\uffe2\uff80\uff90central USA.

Soil N2O emissions from three corn (Zea mays L.)\uffe2\uff80\uff93soybean [Glycine max (L.) Merr.] systems in central Iowa were measured from the spring of 2003 through February 2005. The three managements systems evaluated were full\uffe2\uff80\uff90width tillage (fall chisel plow, spring disk), no\uffe2\uff80\uff90till, and no\uffe2\uff80\uff90till with a rye (Secale cereale L. \uffe2\uff80\uff98Rymin\uffe2\uff80\uff99) winter cover crop. Four replicate plots of each treatment were established within each crop of the rotation and both crops were present in each of the two growing seasons. Nitrous oxide fluxes were measured weekly during the periods of April through October, biweekly during March and November, and monthly in December, January, and February. Two polyvinyl chloride rings (30\uffe2\uff80\uff90cm diameter) were installed in each plot (in and between plant rows) and were used to support soil chambers during the gas flux measurements. Flux measurements were performed by placing vented chambers on the rings and collecting gas samples 0, 15, 30, and 45 min following chamber deployment. Nitrous oxide fluxes were computed from the change in N2O concentration with time, after accounting for diffusional constraints. We observed no significant tillage or cover crop effects on N2O flux in either year. In 2003 mean N2O fluxes were 2.7, 2.2, and 2.3 kg N2O\uffe2\uff80\uff90N ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921 from the soybean plots under chisel plow, no\uffe2\uff80\uff90till, and no\uffe2\uff80\uff90till + cover crop, respectively. Emissions from the chisel plow, no\uffe2\uff80\uff90till, and no\uffe2\uff80\uff90till + cover crop plots planted to corn averaged 10.2, 7.9, and 7.6 kg N2O\uffe2\uff80\uff90N ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921, respectively. In 2004 fluxes from both crops were higher than in 2003, but fluxes did not differ among the management systems. Fluxes from the corn plots were significantly higher than from the soybean plots in both years. Comparison of our results with estimates calculated using the Intergovernmental Panel on Climate Change default emission factor of 0.0125 indicate that the estimated fluxes underestimate measured emissions by a factor of 3 at our sites.

Intensive use of N fertilizers in modern agriculture is motivated by the economic value of high grain yields and is generally perceived to sequester soil organic C by increasing the input of crop residues. This perception is at odds with a century of soil organic C data reported herein for the Morrow Plots, the world's oldest experimental site under continuous corn (Zea maysL.). After 40 to 50 yr of synthetic fertilization that exceeded grain N removal by 60 to 190%, a net decline occurred in soil C despite increasingly massive residue C incorporation, the decline being more extensive for a corn\uffe2\uff80\uff93soybean (Glycine maxL. Merr.) or corn\uffe2\uff80\uff93oats (Avena sativaL.)\uffe2\uff80\uff93hay rotation than for continuous corn and of greater intensity for the profile (0\uffe2\uff80\uff9346 cm) than the surface soil. These findings implicate fertilizer N in promoting the decomposition of crop residues and soil organic matter and are consistent with data from numerous cropping experiments involving synthetic N fertilization in the USA Corn Belt and elsewhere, although not with the interpretation usually provided. There are important implications for soil C sequestration because the yield\uffe2\uff80\uff90based input of fertilizer N has commonly exceeded grain N removal for corn production on fertile soils since the 1960s. To mitigate the ongoing consequences of soil deterioration, atmospheric CO2enrichment, and NO3\uffe2\uff88\uff92pollution of ground and surface waters, N fertilization should be managed by site\uffe2\uff80\uff90specific assessment of soil N availability. Current fertilizer N management practices, if combined with corn stover removal for bioenergy production, exacerbate soil C loss.

Multiple lines of evidence suggest that plant water-use efficiency (WUE)\uffe2\uff80\uff94the ratio of carbon assimilation to water loss\uffe2\uff80\uff94has increased in recent decades. Although rising atmospheric CO 2 has been proposed as the principal cause, the underlying physiological mechanisms are still being debated, and implications for the global water cycle remain uncertain. Here, we addressed this gap using 30-y tree ring records of carbon and oxygen isotope measurements and basal area increment from 12 species in 8 North American mature temperate forests. Our goal was to separate the contributions of enhanced photosynthesis and reduced stomatal conductance to WUE trends and to assess consistency between multiple commonly used methods for estimating WUE. Our results show that tree ring-derived estimates of increases in WUE are consistent with estimates from atmospheric measurements and predictions based on an optimal balancing of carbon gains and water costs, but are lower than those based on ecosystem-scale flux observations. Although both physiological mechanisms contributed to rising WUE, enhanced photosynthesis was widespread, while reductions in stomatal conductance were modest and restricted to species that experienced moisture limitations. This finding challenges the hypothesis that rising WUE in forests is primarily the result of widespread, CO 2 -induced reductions in stomatal conductance.

The Food and Drug Administration (FDA) can regulate the introduction of new tobacco products and some changes to existing products. Cigarette packs have been used as a marketing tool to target specific groups and priority populations. Research has shown that sexual and gender minority (SGM) adults are substantially more likely to use tobacco products than their straight and cisgender counterparts. However, research to inform the FDA\u2019s regulatory decisions regarding cigarette packs targeting priority populations is nascent. To fill this gap, we conducted an online experiment in 2018, randomizing U.S. adults who reported current smoking ( N = 954, 52% were SGM) to view one of three cigarette packs. A graphic designer developed \u201cGlacier\u201d branded packs with three levels of SGM imagery: (1) no targeting, (2) subtle targeting, and (3) a rainbow \u201cpride edition.\u201d Participants viewed and rated the pack using cognitive, affective, and behavioral measures informed by theory. We used a linear model framework to compare the two SGM-targeted packs with the not targeted version and tested interactions between pack and SGM identity for the dependent variables. We stratified results by SGM status. SGM status was a significant moderator of the relationship between the pack and ratings of appeal, positive affect, feeling shocked, and intent to try with a coupon. Findings from this study revealed that packs designed for SGM populations can disproportionately change cognitive, affective, and behavioral intention responses for SGM smokers. Products entering the market should be assessed by FDA for the appeal of their packs to vulnerable populations.

Meeting end\uffe2\uff80\uff90of\uffe2\uff80\uff90century global warming targets requires aggressive action on multiple fronts. Recent reports note the futility of addressing mitigation goals without fully engaging the agricultural sector, yet no available assessments combine both nature\uffe2\uff80\uff90based solutions (reforestation, grassland and wetland protection, and agricultural practice change) and cellulosic bioenergy for a single geographic region. Collectively, these solutions might offer a suite of climate, biodiversity, and other benefits greater than either alone. Nature\uffe2\uff80\uff90based solutions are largely constrained by the duration of carbon accrual in soils and forest biomass; each of these carbon pools will eventually saturate. Bioenergy solutions can last indefinitely but carry significant environmental risk if carelessly deployed. We detail a simplified scenario for the United States that illustrates the benefits of combining approaches. We assign a portion of non\uffe2\uff80\uff90forested former cropland to bioenergy sufficient to meet projected mid\uffe2\uff80\uff90century transportation needs, with the remainder assigned to nature\uffe2\uff80\uff90based solutions such as reforestation. Bottom\uffe2\uff80\uff90up mitigation potentials for the aggregate contributions of crop, grazing, forest, and bioenergy lands are assessed by including in a Monte Carlo model conservative ranges for cost\uffe2\uff80\uff90effective local mitigation capacities, together with ranges for (a) areal extents that avoid double counting and include realistic adoption rates and (b) the projected duration of different carbon sinks. The projected duration illustrates the net effect of eventually saturating soil carbon pools in the case of most strategies, and additionally saturating biomass carbon pools in the case of forest management. Results show a conservative end\uffe2\uff80\uff90of\uffe2\uff80\uff90century mitigation capacity of 110 (57\uffe2\uff80\uff93178) Gt CO2e for the U.S., ~50% higher than existing estimates that prioritize nature\uffe2\uff80\uff90based or bioenergy solutions separately. Further research is needed to shrink uncertainties, but there is sufficient confidence in the general magnitude and direction of a combined approach to plan for deployment now.To assess the association of Life's Essential 8 (LE8) and the presence of abdominal aortic calcification (AAC) with mortality among middle\uffe2\uff80\uff90aged and older individuals.

Methods

Participants aged older than 40\uffe2\uff80\uff89years were enrolled from the National Health and Nutrition Examination Survey 2013\uffe2\uff80\uff902014. AAC was assessed using dual\uffe2\uff80\uff90energy X\uffe2\uff80\uff90ray absorptiometry. Mortality data were ascertained through linkage with the National Death Index until 31 December 2019. The LE8 score incorporates eight components: diet, physical activity, nicotine exposure, sleep health, body mass index, blood lipids, blood glucose and blood pressure. The total LE8 score, an unweighted average of all components, was categorized into low (0\uffe2\uff80\uff9049), medium (50\uffe2\uff80\uff9079) and high (80\uffe2\uff80\uff90100) scores.

Results

This study included 2567 individuals, with a mean LE8 score of 67.28\uffe2\uff80\uff89\uffc2\uffb1\uffe2\uff80\uff890.48 and an AAC prevalence of 28.28%. Participants with low LE8 scores showed a significantly higher prevalence of AAC (odds ratio\uffe2\uff80\uff89=\uffe2\uff80\uff892.12 [1.12\uffe2\uff80\uff904.19]) compared with those with high LE8 scores. Over a median 6\uffe2\uff80\uff90year follow\uffe2\uff80\uff90up, there were 222 all\uffe2\uff80\uff90cause deaths, and 55 cardiovascular deaths occurred. Participants with AAC had an increased risk of all\uffe2\uff80\uff90cause (hazard ratio [HR]\uffe2\uff80\uff89=\uffe2\uff80\uff892.17 [1.60\uffe2\uff80\uff902.95]) and cardiovascular (HR\uffe2\uff80\uff89=\uffe2\uff80\uff892.35 [1.40\uffe2\uff80\uff903.93]) mortality. Moreover, individuals with AAC and low or medium LE8 scores exhibited a 137% (HR\uffe2\uff80\uff89=\uffe2\uff80\uff892.37 [1.58\uffe2\uff80\uff903.54]) and 119% (HR\uffe2\uff80\uff89=\uffe2\uff80\uff892.19 [1.61\uffe2\uff80\uff902.99]) higher risk of all\uffe2\uff80\uff90cause mortality, as well as a 224% (HR\uffe2\uff80\uff89=\uffe2\uff80\uff893.24 [1.73\uffe2\uff80\uff906.04]) and 125% (HR\uffe2\uff80\uff89=\uffe2\uff80\uff892.25 [1.24\uffe2\uff80\uff904.09]) increased risk of cardiovascular mortality, respectively.

Conclusions

The LE8 score correlates with AAC prevalence in middle\uffe2\uff80\uff90aged and older individuals and serves as a valuable tool for evaluating the risk of all\uffe2\uff80\uff90cause and cardiovascular mortality in individuals with AAC.

An important consideration in the treatment of patients with psoriatic arthritis (PsA) is whether the addition of methotrexate (MTX) to biologics has greater efficacy than biologic monotherapy with respect to efficacy outcomes in these patients.

Objectives

To conduct a network meta-analysis (NMA) comparing biologics by treatment class with and without MTX for treatment of adults with active PsA.

Methods

A systematic literature review (SLR) identified randomised, double-blinded, controlled trials, and a Bayesian NMA compared biologics with and without MTX by treatment class (tumour necrosis factor inhibitors (TNFi), interleukin-23 inhibitors (IL-23i) and IL-17i). Efficacy outcomes included American College of Rheumatology 20%, 50% and 70% (ACR20, ACR50 and ACR70) improvement response.

Results

The SLR initially identified 31 studies, of which 17 met feasibility criteria for the NMA by containing the \uffe2\uff80\uff98without MTX\uffe2\uff80\uff99 subgroup. For ACR20 efficacy (the most robust assessment examined), all active treatments were significantly better than placebo. No statistically significant differences were demonstrated between biologic monotherapy (for all classes examined) and biologics in combination with MTX for ACR20/50. IL-17i were comparable to IL-23i, and IL-17i were significantly better than TNFi for ACR20. Although limited by fewer trials, TNFi, IL-23i and IL-17i were not statistically different for ACR50/70.

Conclusions

Concomitant use of MTX and biologics did not improve ACR efficacy outcomes versus biologic monotherapy. MTX does not appear to be necessary as a background therapy when biologics are used for the achievement of ACR20/50 responses in patients with PsA.

Furthermore, yield was predicted for all the possible weather scenarios approximated by 15 historical weather instances contained in the dataset. Using predicted yields and covariance between varieties through different weather scenarios, we performed portfolio optimisation. In this way, for each subregion, we obtained a selection of varieties, that proved superior to others in terms of the amount and stability of yield.
