Fish predation cues induce drifting and emergence in an experimental stream mesocosm system

open access: yesLimnology and Oceanography, Volume 70, Issue S2, Page S364-S376, December 2025.
Abstract Predator–prey interactions are important drivers of adaptation in aquatic communities, shaping the behavior of invertebrates with cascading effects on community dynamics. Behavioral responses, such as moving with the downstream current (drift) or altering the timing of emergence, are strategies that reduce the risk of predator encounters ...

Discharge and nutrients interact to determine trophic structure in a wetland: Evidence from a landscape‐scale manipulation

open access: yesLimnology and Oceanography, Volume 70, Issue 11, Page 3355-3369, November 2025.
Abstract Identifying drivers of consumer biomass patterns and community structure is complex for managed freshwater ecosystems that are sensitive to nutrients and drought. In the Florida Everglades, flow restoration is expected to reintroduce discharge across an expansive wetland, yet most research on consumers has focused on water depth and dry ...

Classification of Planorbidae cellected from Geum river basin

open access: yesThe Korean Journal of Parasitology, 1983
The distribution, external morphology, radula, chromosome numbers of Planorbidae snails were studied. 1. The specimens were collected at four stations in Nonsangun, Kongjugun, and Daedukgun which are located around Geum river. Three genera and three species of Planorbidae, Hippeutis cantori, Segmentina hemisphaerula and Gyraulus convexiusculus, were ...

Where Do You Fly From? Assessing Aerial Dispersal in Temporary Rivers Using Stable Isotopes

open access: yesFreshwater Biology, Volume 70, Issue 10, October 2025.
ABSTRACT Dispersal is a crucial ecological process that facilitates gene flow and species exchange within ecosystems. In temporary rivers (TRs), dispersal is a key driver of community assembly because it determines the ability of the organisms to adapt to seasonal drying and maintain stable populations.

Effects of competition and predation risk from a life history intraguild predator on individual specialisation

open access: yesJournal of Animal Ecology, Volume 94, Issue 9, Page 1811-1822, September 2025.
Individual niche specialisation is widespread within animal populations and can have important ecological consequences. Predation and competition are known drivers of individual specialisation, but their combined effects are unstudied. This mesocosm experiment shows that competition and predation from a single antagonist can have variable effects on ...
