This study evaluates the effects of long-term sheep grazing in salt marshes on the diversity of moths and derives conclusive management suggestions for the conservation of invertebrate diversity in salt marshes. Study sites were located on the Hamburger Hallig, on the Western coast of Schleswig-Holstein, Germany. Between 2006 and 2009, salt marshes that have been under four levels of livestock density (0, 1-2 sheep/ha, 3-4 sheep/ha, 10 sheep/ha) for over 20 years were sampled using light traps and photoeclectors. Plant and moth species richness were highest under low stocking densities, moth species richness, however, showed no difference between low stocking densities and abandonment. Species richness of moths was only weakly correlated with vegetation parameters (species richness, vegetation height, cover and litter). Using additive diversity partitioning we show that no single grazing treatment harbored all recorded moth species and that grazing increases habitat heterogeneity within each treatment. Additionally, we show that moths react more sensitively to grazing than plants, and that therefore assessments of plant species richness in salt marshes do not allow conclusions on invertebrate diversity. For the evaluation of salt-marsh diversity, a multi-species approach should be favored combining plant and invertebrate assessments. A mosaic of abandoned sites and sites with low and intermediate stocking densities would benefit moth diversity in salt-marsh conservation. (C) 2011 Elsevier Ltd. All rights reserved.

The biogeochemistry of P has received much attention as P-enrichment is expected to negatively impact on species diversity in wetlands. It is known that N, sulphur (S) and hydrological conditions affect the biogeochemistry of P, yet their interactive effects on P-dynamics are largely unknown. Additionally, in Europe, climate change has been predicted to lead to increases in summer drought. We performed a greenhouse experiment to elucidate the interactive effects of N, S and a single drought event on the P-availability for Phalaris arundinacea. Additionally, the response of plant phosphatase activity to these factors was measured over the two year experimental period. In contrast to results from earlier experiments, our treatments hardly affected soil P-availability. This may be explained by the higher pH in our soils, hampering the formation of Fe-P or Fe-Al complexes. Addition of S, however, decreased the plants N:P ratio, indicating an effect of S on the N:P stoichiometry and an effect on the plant's P-demand. Phosphatase activity increased significantly after addition of S, but was not affected by the addition of N or a single drought event. Root phosphatase activity was also positively related to plant tissue N and P concentrations, plant N and P uptake, and plant aboveground biomass, suggesting that the phosphatase enzyme influences P-biogeochemistry. Our results demonstrated that it is difficult to predict the effects of wetland restoration, since the involved mechanisms are not fully understood. Short-term and long-term effects on root phosphatase activity may differ considerably. Additionally, the addition of S can lead to unexpected effects on the biogeochemistry of P.

The global spread of woody plants into grasslands is predicted to increase over the coming century. While there is general agreement regarding the anthropogenic causes of this phenomenon, its ecological consequences are less certain. We analysed how woody vegetation of differing cover affects plant diversity (richness and evenness) and the surrogates of multiple ecosystem processes (multifunctionality) in global drylands, and how these change with aridity.

Location

Two hundred and twenty\uffe2\uff80\uff90four dryland sites from all continents except Antarctica, widely differing in their environmental conditions (from arid to dry\uffe2\uff80\uff90subhumid sites) and relative woody cover (from 0 to 100%).

Methods

Using a standardized field survey, we measured the cover, richness and evenness of perennial vegetation. At each site, we measured 14 soil variables related to fertility and the build\uffe2\uff80\uff90up of nutrient pools. These variables are critical for maintaining ecosystem functioning in drylands.

Results

Species richness and ecosystem multifunctionality were strongly related to woody vegetation, with both variables peaking at a relative woody cover (RWC) of 41\uffe2\uff80\uff9360%. This relationship shifted with aridity. We observed linear positive effects of RWC in dry\uffe2\uff80\uff90subhumid sites. These positive trends shifted to hump\uffe2\uff80\uff90shaped RWC\uffe2\uff80\uff93diversity and multifunctionality relationships under semi\uffe2\uff80\uff90arid environments. Finally, hump\uffe2\uff80\uff90shaped (richness, evenness) or linear negative (multifunctionality) effects of RWC were found under the most arid conditions.

Main conclusions

Plant diversity and multifunctionality peaked at intermediate levels of woody cover, although this relationship became increasingly positive in wetter environments. This comprehensive study accounts for multiple ecosystem attributes across a range of levels of woody cover and environmental conditions. Our results help us to reconcile contrasting views of woody encroachment found in the current literature and can be used to improve predictions of the likely effects of encroachment on biodiversity and ecosystem services.

Question: We studied the development and persistence of the effects of nutrient pulses on biomass production and species composition in a fen meadow.

Location: Nature reserve, central Netherlands, 5 m a.s.l.

Methods: Single pulse fertilization with N and P in a factorial design on an undrained central and a drained margin site in a species\uffe2\uff80\uff90rich fen meadow (Cirsio dissecti\uffe2\uff80\uff90Molinietum). Biomass production and species composition were monitored during four years.

Results: At the central site, N addition boosted biomass production, but only during one year. The species composition was not changed. P fertilization increased the biomass production and changed the species composition from a vegetation dominated by Carex panicea to a grassland community with abundant Holcus lanatus, but not before the second year. At the margin site, P fertilization changed the species composition in a similar way, but biomass production was not increased. N fertilization had no effect. At both sites the P induced shift in species composition persisted for four years although the P effect declined during the experiment.

Conclusions: The biomass responses show that N was limiting in the central site. Another nutrient, besides N and P (probably K) must have been limiting in the marginal site. The fast decline of the N effect on biomass is ascribed to increased denitrification and biomass removal. The delay in the P effect on biomass and species composition and the persistence of the P effect on species composition are ascribed to fast immobilisation and subsequent slow release of fertilizer P in the peat soil. Recurrence of the P pulses is expected to cause permanent changes in species composition.

Determining underlying physiological patterns governing plant productivity and diversity in grasslands are critical to evaluate species responses to future environmental conditions of elevated CO2 and nitrogen (N) deposition. In a 9\uffe2\uff80\uff90year experiment, N was added to monocultures of seven C3 grassland species exposed to elevated atmospheric CO2 (560\uffe2\uff80\uff83\uffce\uffbcmol\uffe2\uff80\uff83CO2\uffe2\uff80\uff83mol\uffe2\uff88\uff921) to evaluate how N addition affects CO2 responsiveness in species of contrasting functional groups. Functional groups differed in their responses to elevated CO2 and N treatments. Forb species exhibited strong down\uffe2\uff80\uff90regulation of leaf Nmass concentrations (\uffe2\uff88\uff9226%) and photosynthetic capacity (\uffe2\uff88\uff9228%) in response to elevated CO2, especially at high N supply, whereas C3 grasses did not. Hence, achieved photosynthetic performance was markedly enhanced for C3 grasses (+68%) in elevated CO2, but not significantly for forbs. Differences in access to soil resources between forbs and grasses may distinguish their responses to elevated CO2 and N addition. Forbs had lesser root biomass, a lower distribution of biomass to roots, and lower specific root length than grasses. Maintenance of leaf N, possibly through increased root foraging in this nutrient\uffe2\uff80\uff90poor grassland, was necessary to sustain stimulation of photosynthesis under long\uffe2\uff80\uff90term elevated CO2. Dilution of leaf N and associated photosynthetic down\uffe2\uff80\uff90regulation in forbs under elevated [CO2], relative to the C3 grasses, illustrates the potential for shifts in species composition and diversity in grassland ecosystems that have significant forb and grass components.

A commonly observed phenomenon in plant communities is that the addition of a limiting resource leads to an increase in productivity and a decrease in species diversity. We tested the hypothesis that the mechanism underlying this pattern is a disproportionate increase in mortality of smaller or shade\uffe2\uff80\uff94intolerant species in more productive sites caused by reduction of light levels. We added water and/or one of three nutrients (nitrogen, phosphorus, and potassium) to a 1st\uffe2\uff80\uff94old\uffe2\uff80\uff94field community dominated by weedy annuals and measured effect on productivity, species composition, diversity, and light levels after one growing season. Diversity was not clearly related to productivity in this experiment. Watering increased productivity, but, contrary to expectations, had no effect on density of surviving plants, species diversity, or abundance of low\uffe2\uff80\uff94growing species. Almost all the increase in biomass with watering was due to a positive response by Ambrosia artemisiifolia, an upright annual that was the most common species in the canopy in all treatments. The addition of nitrogen had only a small positive effect on productivity, but strongly decreased density of surviving plants, species diversity, and abundance of most low\uffe2\uff80\uff94growing species. Only Ambrosia increased in abundance with nitrogen addition. The phophorus and potassium additions had little effect on the community. We suggest that the high mortality and low diversity in the nitrogen addition plots, but not in the more productive watered plots, was due to limitation by nitrogen earlier than limitation by water during the growing season. The consequence was earlier canopy closure and greater mortality due to light limitation.

Despite their importance, how plant communities and soil microorganisms interact to determine the capacity of ecosystems to provide multiple functions simultaneously (multifunctionality) under climate change is poorly known. We conducted a common garden experiment using grassland species to evaluate how plant functional structure and soil microbial (bacteria and protists) diversity and abundance regulate soil multifunctionality responses to joint changes in plant species richness (one, three and six species) and simulated climate change (3\uffc2\uffb0C warming and 35% rainfall reduction). The effects of species richness and climate on soil multifunctionality were indirectly driven via changes in plant functional structure and their relationships with the abundance and diversity of soil bacteria and protists. More specifically, warming selected for the larger and most productive plant species, increasing the average size within communities and leading to reductions in functional plant diversity. These changes increased the total abundance of bacteria that, in turn, increased that of protists, ultimately promoting soil multifunctionality. Our work suggests that cascading effects between plant functional traits and the abundance of multitrophic soil organisms largely regulate the response of soil multifunctionality to simulated climate change, and ultimately provides novel experimental insights into the mechanisms underlying the effects of biodiversity and climate change on ecosystem functioning.Despite their importance, how plant communities and soil microorganisms interact to determine the capacity of ecosystems to provide multiple functions simultaneously (multifunctionality) under climate change is poorly known.
