Invasive Eurasian Minnow Alters the Trophic Niche and Growth of Brown Trout in High‐Latitude Lakes

Ecology of Freshwater Fish, Volume 35, Issue 1, January 2026.
ABSTRACT Invasive species pose a major threat to aquatic ecosystems, particularly in high‐latitude lakes which are characterised by low biodiversity. In northern Europe, the Eurasian minnow (Phoxinus phoxinus) has colonised lakes historically dominated by salmonids, raising concerns about the impacts of invasive cyprinids on native fish populations and

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

Limnology 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

Limnology 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 ...

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

Freshwater 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

Journal 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 ...

Parasites inBulinus senegalensis(Mollusca: Planorbidae)and their detection

Parasitology, 1979
SUMMARYIsoelectric focusing studies on enzyme variation between populations of the snailBulinus senegalensisrevealed that parasitic infections in the snails contributed additional bands of enzyme activity, particularly in the glucose phosphate isomerase (GPI) and malate dehydrogenase (MDH) systems. The patterns due to the parasite enzymes were, in most

The Nature of Oceanic Dispersal in the Diversification Process on Insular Systems in Asia

Global Ecology and Biogeography, Volume 34, Issue 9, September 2025.
ABSTRACT Aim To clarify the characteristics and contribution of oceanic dispersal (OD), a representative of long‐distance dispersal, to phylogenetic diversification on insular systems. Location Eastern Eurasia. Time Period Post‐Neogene. Major Taxa Studied Freshwater snails of the genus Gyraulus (Mollusca: Gastropoda). Methods We conducted comprehensive
