Climate change is expected to increase the frequency and severity of droughts. These events, which can cause significant perturbations terrestrial ecosystems potentially long-term impacts on ecosystem structure functioning after drought has subsided are often called 'drought legacies'. While immediate effects have been comparatively well characterized, our broader understanding legacies just emerging. Drought relate all aspects functioning, involving changes at species community scale as alterations soil properties. This consequences for responses subsequent drought. Here, we synthesize current knowledge underlying mechanisms. We highlight relevance legacy duration different processes using examples carbon cycling composition. present hypotheses characterizing how intrinsic (i.e. biotic abiotic properties processes) extrinsic timing, severity, frequency) factors could alter resilience trajectories under scenarios recurrent events. propose ways improving their implications needed assess longer-term droughts functioning.

Biodiversity promotes ecosystem functioning despite environmental change

Published: Dec. 2, 2021

Abstract Three decades of research have demonstrated that biodiversity can promote the functioning ecosystems. Yet, it is unclear whether positive effects on ecosystem will persist under various types global environmental change drivers. We conducted a meta‐analysis 46 factorial experiments manipulating both species richness and environment to test how drivers (i.e. warming, drought, nutrient addition or CO 2 enrichment) modulated effect multiple functions across three taxonomic groups (microbes, phytoplankton plants). found increased in ambient manipulated environments, but often not same degree. In particular, were larger stressful environments induced by drivers, indicating high‐diversity communities more resistant change. Using subset studies, we also mainly driven interspecific complementarity these over time environments. Our findings support conservation as key strategy for sustainable management face

Global root traits (GRooT) database

Global Ecology and Biogeography, Journal Year: 2020, Volume and Issue: 30(1), P. 25 - 37

Published: Sept. 9, 2020

Abstract Motivation Trait data are fundamental to the quantitative description of plant form and function. Although root traits capture key dimensions related responses changing environmental conditions effects on ecosystem processes, they have rarely been included in large‐scale comparative studies global models. For instance, remain absent from nearly all that define spectrum Thus, overcome conceptual methodological roadblocks preventing a widespread integration trait into analyses we created Global Root (GRooT) Database. GRooT provides ready‐to‐use by combining expertise ecologists with mobilization curation. Specifically, (a) determined set core relevant function based an assessment experts, (b) maximized species coverage through standardization within among traits, (c) implemented quality checks. Main types variables contained contains 114,222 records 38 continuous traits. Spatial location grain arid, continental, polar, temperate tropical biomes. Data were derived experimental field studies. Time period recorded between 1911 2019.

Biotic homogenization destabilizes ecosystem functioning by decreasing spatial asynchrony

Ecology, Journal Year: 2021, Volume and Issue: 102(6)

Published: March 11, 2021

Abstract Our planet is facing significant changes of biodiversity across spatial scales. Although the negative effects local (α diversity) loss on ecosystem stability are well documented, consequences at larger scales, in particular biotic homogenization, that is, reduced species turnover space (β diversity), remain poorly known. Using data from 39 grassland experiments, we examine β diversity simulated landscapes while controlling for potentially confounding and abiotic factors. results show higher generates more asynchronous dynamics among communities thereby contributes to productivity We further quantify relative contributions α find a relatively stronger effect diversity, possibly due limited scale our experiments. The stabilizing both lead positive diversity–stability relationship landscape scale. findings demonstrate destabilizing homogenization suggest should be conserved multiple scales maintain functions services.
