Impacts of aqueous extracts of tree leaves on the aquatic snail Potamopyrgus antipodarum: exploring the roles of leaf habit and geographic origin - Aquatic Ecology The introduction of exotic tree species with dissimilar leaf habits or distinctive chemical composition into native communities may cause impacts on aquatic organisms, yet the relative influence of leaf habit and geographic origin on those impacts remain poorly understood. In this study, we experimentally explored the ecotoxicological effects of aqueous leaf litter extracts from 15 tree species differing in leaf habit (deciduous vs evergreen) and geographic origin (exotics vs natives in Spain) on the mortality and behavior of the aquatic snail Potamopyrgus antipodarum (Gray, 1843). Snails were exposed for 7 days to three leaf extract concentrations of each tree species. No mortality effects were observed at any concentration. In contrast, the behavioral responses of snails were negatively affected at the highest concentration, showing increased reaction time and reduced speed. These responses were species-specific and associated with leaf habit and chemical composition of extracts rather than geographic origin. Leaf extracts from deciduous trees caused a greater slowing down of snails than extracts from evergreen trees. Overall, our results indicate that leaf litter impacts on Potamopyrgus antiporadrum depend more on tree species identity and leaf habit than on native or exotic status, highlighting the importance of leaf traits when assessing ecotoxicological risks in freshwater ecosystems.

Transport is not one-size-fits-all, because water moves differently across systems!

Lakes show short, depth-structured signals.
Rivers vary with discharge and particle size.
Coastal and open ocean waters can carry eDNA fa, yet still reflect local sources. 🌊📍

State biologists advise sampling, local removals to tackle Duck Lake’s grass carp problem Washington Department of Fish and Wildlife staff told the Ocean Shores Freshwater Advisory Board that historic grass carp stockings and an illegal introduction of yellow perch have transformed Duck Lake’s ecology. WDFW recommended sampling carp to test for fertility, encouraged rescinding a local ordinance that limits bowfishing, and outlined costs

Duck Lake's fishery is collapsing due to invasive species and decades-old grass carp stockings, prompting urgent community action to restore its ecosystem.

Sonar monitoring shows largest Chinook run on Smith River since program began; seals and sturgeon observed A sonar monitoring presentation to the Del Norte County Fish and Game Commission reported a 2024–25 Chinook estimate of 27,427 fish, a single-day peak of 3,585 on Oct. 27, expanded pinniped detections and yearly variation in steelhead counts; the presenter warned of data loss during high flows and funding limits for long-term monitoring.

A groundbreaking sonar study on the Smith River has revealed a record-breaking Chinook salmon run of 27,427 fish, raising questions about the impact of predators and the future of this vital species.
