Phosphorus addition decreases plant lignin but increases microbial necromass contribution to soil organic carbon in a subalpine forest

"The underlying mechanisms via which phosphorus (P) drives plant and microbial regulation of soil organic carbon (SOC) formation and stabilization remain unclear. Taking the advantage of an 8-year field experiment with multi-level P additions in a subalpine forest, we found that P addition in the subalpine forest over 8 years influenced SOC composition through divergent alterations of plant- and microbial-derived C contributions, but did not shape SOC physical and chemical stability. These findings may aid in accurately forecasting SOC dynamics and their potential feedbacks to climate change with future scenarios of increasing soil P availability in Earth system models."

Successive extreme climatic events lead to immediate, large‐scale, and diverse responses from fish in the Arctic

"Peaks in bottom temperature were observed concomitantly to surface extreme climatic events (ECEs). Bottom fish community responded immediately with large scale relocations. Responses varied among and within species with diverse adaptive capacity to short term perturbations. Species responses varied from one ECE to another, although the environmental signals were similar. This study highlights the complexity of species and community responses to successive ECEs. Long time series of multiple ECEs are needed to better understand ecosystems response mechanims, and sustainable management recquires models to better represent stochastic events."

Surface temperatures reveal patterns of vegetation water stress and their environmental drivers across the tropical Americas

"We developed a new methodology to improve our understanding of vegetation water stress, based on remotely sensed land surface and near surface atmospheric temperatures and applied it in the tropical Americas. We showed where radiation, atmospheric dryness and precipitation control variations of water stress, pinpointed critical thresholds for water stress, and quantified reductions in ecosystem carbon uptake associated with crossing these critical thresholds. We found that carbon uptake by gross primary production can be reduced by up to 80% from water stress, and demonstrate that vegetation structure and diversity can be important for regulating surface energy and carbon fluxes."

Identifying climate thresholds for dominant natural vegetation types at the global scale using machine learning: Average climate versus extremes

"We explore large-scale relationships between vegetation and climatic characteristics and search for globally important climatic thresholds involved in structuring the distribution of dominant vegetation using machine-learned decision trees. Our results highlight the importance of climate extremes in shaping present global vegetation distributions and predicting future vegetation changes. The identification of climatic thresholds for dominant vegetation types can improve the understanding of current and future vegetation processes as well as the thresholds in Dynamic Global Vegetation Models (DGVMs)."

Cool Microrefugia Accumulate and Conserve Biodiversity Under Climate Change

"Climate change biologists often overlook microclimates because they are difficult to map. Here, we map microclimates in freshwater rock pools and evaluate how accounting for microclimates alters predictions of climate change impacts on aquatic invertebrates. We demonstrate that maximum temperature during the growing season can differ by 12°C among microclimates only meters apart. We predict that cool microclimates will accumulate biodiversity because they remain suitable for cold-adapted species and become suitable for warm-adapted species. Hence, protecting a small number of cool microclimates can help conserve regional biodiversity, and is a much better strategy than conserving the currently most diverse locations."

Climate legacies determine grassland responses to future rainfall regimes

"Historic precipitation manipulations in tallgrass prairie resulted in multi-year carbon cycling legacy effects. Our study suggests that the sensitivity of carbon fluxes to climate perturbations can be shaped by previous climate patterns."

Persistent thermally‐driven shift in the functional trait structure of herbivorous fishes: evidence of top‐down control on the rebound potential of temperate seaweed forests?

"We demonstrate a legacy effect of an extreme marine heatwave (MHW) in the structure and functioning of a temperate reef ecosystem. The trait structure of herbivorous fishes shifted following the MHW, with novel herbivore roles supported by range-expanding tropical fishes. This new functional structure appears to be stable ten years after the MHW, despite returning cool conditions and winter cold spells, potentially contributing to the replacement of the formerly dominant kelp Ecklonia radiata by ‘turfs’ and Sargassum spp. Our study exemplifies the lasting consequences of phenotypic (trait-mediated) changes in the nature of core ecosystem processes in changing temperate reefs."

Contrasting drivers of belowground nitrogen cycling in a montane grassland exposed to a multifactorial global change experiment with elevated CO2, warming and drought

"Organic nitrogen (N) cycling is recognized as the major process controlling the overall soil N cycle, yet few studies investigated global change responses of soil organic N breakdown. We focused on the interactive effects of multiple global change drivers (warming x CO2 x drought) on soil protein depolymerization and microbial amino acid consumption. We found a shift in controls of these processes, from plant controls under warming and elevated CO2, to microbial turnover and soil organic N availability under push disturbances (drought). Seasonality modulated the effects of warming by changing the factors limiting soil organic nitrogen cycling."
