Both gradual and extreme weather changes trigger complex ecological responses in river
ecosystems. It is still unclear to what extent trend or event effects alter biodiversity and …

Droughts, or severe reductions of water flow, are expected to become more frequent and
intense in rivers in many regions under the ongoing climate change scenario. It is therefore …

Nonperennial streams dominate global river networks and are increasing in occurrence
across space and time. When surface flow ceases or the surface water dries, flow or …

Investigating the influence of biodiversity on ecosystem functioning over environmental
gradients is needed to anticipate ecosystem responses to global change. However, our …

Flow interruption in intermittent rivers (IRs) generates a mosaic of terrestrial and aquatic
habitats across the river network affecting ecosystem processes, as organic matter (OM) …

Microbiota inhabiting the intermittent streambeds mediates several in-stream processes that
are essential for ecosystem function. Reduced stream discharge caused by the …

The microbial decomposition of organic matter is a fundamental ecosystem process that
transforms organic matter and fuels detritus-based food webs, influencing biogeochemical …

Aquatic fungi are highly diverse organisms that play a critical role in global biogeochemical
cycles. Yet it remains unclear which assembly processes determine their co-occurrence and …

Biodiversity loss, exotic plant invasion and climatic change are three important global
changes that can affect litter decomposition. These effects may be interactive and these …

Human-induced salinization of freshwaters constitutes a growing global problem, whose
consequences on streams functioning are largely unknown. Climate change projections …
