The habitat use of ariid catfishes in coral reefs in northeastern Brazil

Journal of Fish Biology, EarlyView.
Abstract Ariidae species occur across a wide range of habitats from freshwater to fully marine environments and are typically associated with soft‐bottom substrates. However, they are sometimes associated with hard‐bottom substrates such as coral reefs, but such association is poorly documented.

Sex‐dependent divergence in river use following maturation in Japanese seabass Lateolabrax japonicus revealed by otolith Sr:Ca chronologies

Journal of Fish Biology, EarlyView.
Abstract Partial migration, in which migratory and resident individuals coexist within a population, is widespread in fishes and contributes to population resilience. However, the role of sex in shaping migratory strategies remains poorly understood. Herein, we examined partial migration in Japanese seabass Lateolabrax japonicus using sex ratios and ...

Early results and lessons learned from biomanipulation and chemical restoration of a eutrophic shallow lake

Restoration Ecology, EarlyView.
Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...
