Abstract As the United Nations develops a post-2020 global biodiversity framework for the
Convention on Biological Diversity, attention is focusing on how new goals and targets for …

Conceptual models underpin river ecosystem research. However, current models focus on
continuously flowing rivers and few explicitly address characteristics such as flow cessation …

Streams and rivers provide important services to humans, and therefore, their ecological
integrity should be a societal goal. Although ecological integrity encompasses structural and …

Non-perennial streams are widespread, critical to ecosystems and society, and the subject
of ongoing policy debate. Prior large-scale research on stream intermittency has been …

Human impacts, particularly nutrient pollution and land‐use change, have caused significant
declines in the quality and quantity of freshwater resources. Most global assessments have …

Over half of global rivers and streams lack perennial flow, and understanding the distribution
and drivers of their flow regimes is critical for understanding their hydrologic …

Periphyton (viz. algal) growth in many freshwater systems is associated with severe
eutrophication that can impair productive and recreational use of water by billions of people …

Climate change is rapidly driving global biodiversity declines. How wetland
macroinvertebrate assemblages are responding is unclear, a concern given their vital …

Understanding large‐scale drivers of biodiversity in palustrine wetlands is challenging due
to the combined effects of macroclimate and local edaphic conditions. In boreal and …

Broad-scale studies of species distributions and diversity have contributed to the emergence
of general macroecological rules. These rules are typically founded on research using well …
