Significance One of the greatest challenges in projecting future shifts global climate is understanding how soil respiration rates will change with warming. Multiple experimental warming studies have explored this response, but no consensus has been reached. Based on a synthesis 27 spanning nine biomes, we find that although increases rates, there limited evidence for shifting response We also note universal decline temperature sensitivity at temperatures >25 °C. Together, our data...
Abstract Soil respiration is expected to increase with rising global temperatures but the degree of response may depend on soil moisture and other local factors. Experimental climate change studies from single sites cannot discern whether an observed site‐dependent or generalizable. To deconvolve site‐specific vs. regional climatic controls, we examined for 18 months along a 520 km gradient in three Pacific Northwest, USA prairies that represents increasingly severe Mediterranean conditions...
Whether species will be extirpated in their current geographic ranges due to rapidly changing climate, and if so, whether they can avoid extinction by shifting distributions are pressing questions for biodiversity conservation. However, forecasts of climate change impacts on species' rarely incorporate a demographic understanding responses climate. Because many biotic abiotic factors at multiple scales control range limits, experimentation is essential establish underlying mechanisms. We...
Projected changes in climate are expected to have widespread effects on plant community composition and diversity coming decades. However, multisite, multifactor manipulation studies that examined whether observed responses regionally consistent multiple perturbations interdependent rare. Using such an experiment, we quantified how warming increased precipitation intensity affect the relative dominance of functional groups across a broad gradient Mediterranean prairies. We implemented fully...
Under the midday sun when photosynthesizers are producing oxygen, shallow aquatic ecosystems can become supersaturated with oxygen (>100% air saturation) while they simultaneously peak in water temperature. It has been suggested that supersaturation could protect water-breathing animals from mortality during heatwaves because of potential role governing thermal tolerance. Here, we conducted a circumglobal assessment effects ecologically relevant (150%, hyperoxia) on warming tolerance...
Abstract The path of carbon (C) from plant litter to soil organic matter (SOM) is key understanding how C stocks and microbial decomposition will respond climate change whether sinks can be enhanced. Long‐term ecosystem‐scale manipulations molecular characterization SOM provide a unique opportunity explore these issues. We incubated soils 20‐year input experiment for 525 days asked quantity source (i.e., roots versus aboveground litter) affected cycling, function, the size composition pools....
Abstract Restoring coastal wetland habitats is important for returning many ecosystem services. However, very little known about whether these restoration events return soil microbial functions and C storage to reference‐level capacity. We compared function (microbial enzyme activity, catabolic responses substrates, CH 4 CO 2 gas production) attributes (percent C, bulk density, density) in disturbed, restored, reference wetlands freshwater saline Oregon complexes. found that diking draining...
