Riverine habitats are vulnerable to a host of environmental stressors, many of which are
increasing in frequency and intensity across the globe. Climate change is arguably the …

Recent studies suggest that animals are decreasing in size as a general response to global
warming, for reasons that remain unclear. Here, by analysing ectotherm death time curves …

Organism size is one of the key determinants of community structure, and its relationship
with abundance can describe how biomass is partitioned among the biota within an …

Microbes play numerous roles in stream ecosystems. They carry out key processes in
stream nutrient cycles and are responsible for a large part of organic matter breakdown …

Global warming can affect all levels of biological complexity, though we currently understand
least about its potential impact on communities and ecosystems. At the ecosystem level …

Phytoplankton are key components of aquatic ecosystems, fixing CO2 from the atmosphere
through photosynthesis and supporting secondary production, yet relatively little is known …

Lotic environments contain a disproportionate amount of biodiversity given their relatively
small proportion of the worldwide landscape. We conducted a systematic literature search of …

Environmental warming is predicted to rise dramatically over the next century, yet few
studies have investigated its effects in natural, multi-species systems. We present data …

Freshwater ecosystems are becoming saltier due to human activities. The effects of
increased salinity can lead to cascading trophic interactions, affecting ecosystem functioning …

Natural ecosystems typically consist of many small and few large organisms,,,. The scaling
of this negative relationship between body mass and abundance has important implications …
