Abstract Small, 1st and 2nd-order, headwater streams and ponds play essential roles in
providing natural flood control, trapping sediments and contaminants, retaining nutrients …

Chapter 2, building on prior assessments, provides a global assessment of the observed
impacts and projected risks of climate change to terrestrial and freshwater ecosystems …

New scientific understanding is catalyzed by novel technologies that enhance measurement

Land use change threatens the ecological integrity of tropical rivers and streams; however,
few studies have simultaneously analyzed the taxonomic and functional responses of …

Instream biogeochemical process measurements are often short-term and localized. Here
we use in situ sensors to quantify the net effects of biogeochemical processes on seasonal …

Riparian areas, the interface between land and freshwater ecosystems, are considered to
play a pivotal role in the supply of regulating, provisioning, cultural and supporting services …

The growing threat of abrupt and irreversible changes to the functioning of freshwater
ecosystems compels robust measures of tipping point thresholds. To determine benthic …
