Climate oscillations in the Quaternary forced species to major latitudinal or altitudinal range shifts. It has been suggested that adaptation concomitant with range shifts plays key roles in species responses during climate oscillations, but the role of selection for local adaptation to climatic changes remains largely unexplored. Here, we investigated population structure, demographic history and signatures of climate-driven selection based on genome-wide polymorphism data of 141 Japanese Arabidopsis halleri individuals, with European ones as outgroups. Coalescent-based analyses suggested a genetic differentiation between Japanese subpopulations since the Last Glacial Period (LGP), which would have contributed to shaping the current pattern of population structure. Population demographic analysis revealed the population size fluctuations in the LGP, which were particularly prominent since the subpopulations started to diverge (\uffe2\uff88\uffbc50, 000 years ago). The ecological niche modeling predicted the geographic or distribution range shifts from southern coastal regions to northern coastal and mountainous areas, possibly in association with the population size fluctuations. Through genome-wide association analyses of bioclimatic variables and selection scans, we investigated whether climate-associated loci are enriched in the extreme tails of selection scans, and demonstrated the prevailing signatures of selection, particularly toward a warmer climate in southern subpopulations and a drier environment in northern subpopulations, which may have taken place during or after the LGP. Our study highlights the importance of integrating climate associations, selection scans and population demographic analyses for identifying genomic signatures of population-specific adaptation, which would also help us predict the evolutionary responses to future climate changes.In this study we used meteorological parameters and predictive modelling interpreted by model explanation to develop stress metrics that indicate the presence of drought and heat stress at the specific environment. We started from the extreme temperature and precipitation indices, modified some of them and introduced additional drought indices relevant to the analysis. Based on maize\uffe2\uff80\uff99s sensitivity to stress, the growing season was divided into four stages. The features were calculated throughout the growing season and split in two groups, one for the drought and the other for heat stress. Generated meteorological features were combined with soil features and fed to random forest regression model for the yield prediction. Model explanation gave us the contribution of features to yield decrease, from which we estimated total amount of stress at the environments, which represents new environmental index. Using this index we ranked the environments according to the level of stress. More than 2400 hybrids were tested across the environments where they were grown and based on the yield stability they were marked as either tolerant or susceptible to heat, drought or combined heat and drought stress. Presented methodology and results were produced within the Syngenta Crop Challenge 2019.Rock-dwelling microorganisms are key players in ecosystem functioning of Antarctic ice free-areas. Yet, little is known about their diversity and ecology. Here, we performed metagenomic analyses on rocks from across Antarctica comprising >75,000 viral operational taxonomic units (vOTUS). We found largely undescribed, highly diverse and spatially structured virus communities potentially influencing bacterial adaptation and biogeochemistry. This catalog lays the foundation for expanding knowledge of the virosphere in extreme environments.Thermal adaptations of soil microorganisms could mitigate or facilitate global warming effects on soil organic matter (SOM) decomposition and soil CO2 efflux. We incubated soil from warmed and control subplots of a forest soil warming experiment to assess whether 9\uffc2\uffa0years of soil warming affected the rates and the temperature sensitivity of the soil CO2 efflux, extracellular enzyme activities, microbial efficiency, and gross N mineralization. Mineral soil (0\uffe2\uff80\uff9310\uffc2\uffa0cm depth) was incubated at temperatures ranging from 3 to 23\uffc2\uffa0\uffc2\uffb0C. No adaptations to long\uffe2\uff80\uff90term warming were observed regarding the heterotrophic soil CO2 efflux (R10 warmed: 2.31\uffc2\uffa0\uffc2\uffb1\uffc2\uffa00.15\uffc2\uffa0\uffce\uffbcmol\uffc2\uffa0m\uffe2\uff88\uff922\uffc2\uffa0s\uffe2\uff88\uff921, control: 2.34\uffc2\uffa0\uffc2\uffb1\uffc2\uffa00.29\uffc2\uffa0\uffce\uffbcmol\uffc2\uffa0m\uffe2\uff88\uff922\uffc2\uffa0s\uffe2\uff88\uff921; Q10 warmed: 2.45\uffc2\uffa0\uffc2\uffb1\uffc2\uffa00.06, control: 2.45\uffc2\uffa0\uffc2\uffb1\uffc2\uffa00.04). Potential enzyme activities increased with incubation temperature, but the temperature sensitivity of the enzymes did not differ between the warmed and the control soils. The ratio of C\uffc2\uffa0:\uffc2\uffa0N acquiring enzyme activities was significantly higher in the warmed soil. Microbial biomass\uffe2\uff80\uff90specific respiration rates increased with incubation temperature, but the rates and the temperature sensitivity (Q10 warmed: 2.54\uffc2\uffa0\uffc2\uffb1\uffc2\uffa00.23, control 2.75\uffc2\uffa0\uffc2\uffb1\uffc2\uffa00.17) did not differ between warmed and control soils. Microbial substrate use efficiency (SUE) declined with increasing incubation temperature in both, warmed and control, soils. SUE and its temperature sensitivity (Q10 warmed: 0.84\uffc2\uffa0\uffc2\uffb1\uffc2\uffa00.03, control: 0.88\uffc2\uffa0\uffc2\uffb1\uffc2\uffa00.01) did not differ between warmed and control soils either. Gross N mineralization was invariant to incubation temperature and was not affected by long\uffe2\uff80\uff90term soil warming. Our results indicate that thermal adaptations of the microbial decomposer community are unlikely to occur in C\uffe2\uff80\uff90rich calcareous temperate forest soils.

Although maize is the most highly produced crop worldwide, few studies have evaluated the interactive effects of elevated [CO2] and temperature on its photosynthetic physiology, agronomic traits or biomass, and seed yield under open field conditions. This study investigates the effects of rising [CO2] and warmer temperature, independently and in combination, on maize grown in the field throughout a full growing season. Free\uffe2\uff80\uff90airCO2enrichment (FACE) technology was used to target atmospheric [CO2] to 200\uffc2\uffa0\uffce\uffbcmol\uffc2\uffa0mol\uffe2\uff88\uff921above ambient [CO2] and infrared heaters to target a plant canopy increase of 3.5\uffc2\uffa0\uffc2\uffb0C, with actual season mean heating of ~2.7\uffc2\uffa0\uffc2\uffb0C, mimicking conditions predicted by the second half of this century. Photosynthetic gas\uffe2\uff80\uff90exchange parameters, leaf nitrogen and carbon content, leaf water potential components, and developmental measurements were collected throughout the season, and biomass and yield were measured at the end of the growing season. As predicted for a C4plant, elevated [CO2] did not stimulate photosynthesis, biomass, or yield. Canopy warming caused a large shift in aboveground allocation by stimulating season\uffe2\uff80\uff90long vegetative biomass and decreasing reproductive biomass accumulation at bothCO2concentrations, resulting in decreased harvest index. Warming caused a reduction in photosynthesis due to down\uffe2\uff80\uff90regulation of photosynthetic biochemical parameters and the decrease in the electron transport rate. The reduction in seed yield with warming was driven by reduced photosynthetic capacity and by a shift in aboveground carbon allocation away from reproduction. This field study portends that future warming will reduce yield in maize, and this will not be mitigated by higher atmospheric [CO2] unless appropriate adaptation traits can be introduced into future cultivars.

We assess the potential for 40 practices to address these land challenges and find that: Nine options deliver medium to large benefits for all four land challenges. A further two options have no global estimates for adaptation, but have medium to large benefits for all other land challenges. Five options have large mitigation potential (>3\uffc2\uffa0Gt CO2eq/year) without adverse impacts on the other land challenges. Five options have moderate mitigation potential, with no adverse impacts on the other land challenges. Sixteen practices have large adaptation potential (>25 million people benefit), without adverse side effects on other land challenges. Most practices can be applied without competing for available land. However, seven options could result in competition for land. A large number of practices do not require dedicated land, including several land management options, all value chain options, and all risk management options. Four options could greatly increase competition for land if applied at a large scale, though the impact is scale and context specific, highlighting the need for safeguards to ensure that expansion of land for mitigation does not impact natural systems and food security. A number of practices, such as increased food productivity, dietary change and reduced food loss and waste, can reduce demand for land conversion, thereby potentially freeing\uffe2\uff80\uff90up land and creating opportunities for enhanced implementation of other practices, making them important components of portfolios of practices to address the combined land challenges.We measured leaf photosynthetic traits in shade\uffe2\uff80\uff90grown seedlings of four tree species native to northern Japan, raised under an elevated CO2 condition, to investigate the effects of elevated CO2 on shade tolerance of deciduous broadleaf tree species with different successional traits. We considered Betula platyphylla var. japonica and Betula maximowicziana as pioneer species, Quercus mongolica var. crispula as a mid\uffe2\uff80\uff90successional species, and Acer mono as a climax species. The plants were grown under shade conditions (10% of full sunlight) in a CO2\uffe2\uff80\uff90regulated phytotron. Light compensation points (LCPs) decreased in all tree species when grown under elevated CO2 (720\uffc2\uffa0\uffce\uffbcmol\uffc2\uffb7mol\uffe2\uff88\uff921), which were accompanied by higher apparent quantum yields but no photosynthetic down\uffe2\uff80\uff90regulation. LCPs in Q.\uffc2\uffa0mongolica and A.\uffc2\uffa0mono grown under elevated CO2 were lower than those in the two pioneer birch species. The LCP in Q.\uffc2\uffa0mongolica seedlings was not different from that of A.\uffc2\uffa0mono in each CO2 treatment. However, lower dark respiration rates were observed in A.\uffc2\uffa0mono than in Q.\uffc2\uffa0mongolica, suggesting higher shade tolerance in A.\uffc2\uffa0mono as a climax species in relation to carbon loss at night. Thus, elevated CO2 may have enhanced shade tolerance by lowering LCPs in all species, but the ranking of shade tolerance related to successional traits did not change among species under elevated CO2, i.e. the highest shade tolerance was observed in the climax species (A.\uffc2\uffa0mono), followed by a gap\uffe2\uff80\uff90dependent species (Q.\uffc2\uffa0mongolica), while lower shade tolerance was observed in the pioneer species (B.\uffc2\uffa0platyphylla and B.\uffc2\uffa0maximowicziana).
