Multiscale Environmental Drivers of Aquatic Insect Assemblages in Cerrado Streams
Austral Ecology, Volume 51, Issue 3, March 2026.Multi‐scale drivers of aquatic insect communities in Cerrado streams. The gradient (from left to right) indicates increasing spatial scale, showing that abundance is influenced by local factors (conductivity, temperature), taxonomic richness responds to agricultural land use at an intermediate scale, and community composition is structured by regional ...

Marine Subsidies Fortify a Stronghold for a Freshwater Megafish (Hucho taimen)
Conservation Letters, Volume 19, Issue 2, March/April 2026.ABSTRACT Taimen—the largest salmonids in the world—are among the most at‐risk groups of freshwater megafish. The Tugur River in the Russian Far East is perhaps the greatest stronghold of Siberian taimen (Hucho taimen) and large runs of anadromous chum salmon (Oncorhynchus keta) to this ecosystem may contribute to this conservation success.

Comparison of species richness of light trap-collected caddisfly assemblages (Insecta: Trichoptera) using rarefaction [PDF]
, 2002 ConselVation value of light trap-collected caddisfly assemblages(Insecta: Trichoptera) was evaluated on the basis of their species richness. The assemblage coming from an artificial stream showed a higher conservation value based on species richness than

Persistence of Urban Stream Syndrome Effects from Point Source and Non-Point Source Pollutants [PDF]
, 2017 In a previous study, Sager Creek, a small 1st-3rd order stream in northwest Arkansas was shown to be negatively impacted by urban land usage within the watershed, producing a stream that exhibited several indicators of urban stream syndrome.

Freshwater Conservation Priority Areas Are Threatened by Global Mining Activities
Global Change Biology, Volume 32, Issue 3, March 2026.Meeting global mineral demands, including those for decarbonization, risks amplifying threats to freshwater biodiversity. This study presents the first global mapping of conflicts between mining and freshwater conservation, revealing that mining may contaminate up to 1.8 million km of rivers, with over 18% within conservation priority areas.

Evaluación de los efectos de la urbanización en los arroyos de Tierra del Fuego [PDF]
, 2017 We set out to understand how urbanization affects streams in Ushuaia, Tierra del Fuego. Paired ttestsand linear regressions were used to compare physico-chemical stream habitat variables (i.e., temperature,turbidity, conductivity, dissolved oxygen and pH)

A Modification of the Biotic Index of Organic Stream Pollution to Remedy Problems and Permit Its Use Throughout the Year [PDF]
, 2018 The biotic index of the arthropod fauna of streams is modified by limiting to ten the number of individuals in each taxon used in its calculation. This reduces detrimental effects on the index of certain fairly tolerant taxa in clean streams, effects of ...
