Do offspring characteristics reflect parental migration variation?

open access: yesJournal of Fish Biology, EarlyView.
Abstract Sea trout, Salmo trutta, display a wide range of migratory behaviours, and one aspect of variation comes from freshwater migration distance. The overall aim of this study was to determine if offspring of long‐ and short‐distance migrants exhibited phenotypic differences relating to parental migration distance.

Deciphering the complex life cycle and partial migration of an ecological engineer and critical Neotropical fishery species, Prochilodus costatus

open access: yesJournal of Fish Biology, EarlyView.
Abstract Understanding complex migration patterns, including drivers of partial migration and habitat use, is challenging but essential for conservation, as it determines a species' adaptative capacity in the face of environmental change and anthropogenic threats.

Acoustic telemetry reveals high site fidelity of yellow‐phase American eels Anguilla rostrata in a large river

open access: yesJournal of Fish Biology, EarlyView.
Abstract Movement patterns and habitat use of yellow‐phase American eels Anguilla rostrata in the Wolastoq/Saint John River were examined using acoustic telemetry. Tracking 72 tagged yellow‐phase eels from late summer 2021 to autumn 2023 revealed overall restricted longitudinal movements (mean linear range ± standard deviation [SD] 6.4 ± 10.9 km) and ...

Feeding ecology of an Amazonian electric knifefish under altered flood‐pulse dynamics caused by hydroelectric damming

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study evaluated the effects of the controlled flood pulse on diet composition, trophic niche breadth and feeding intensity of Archolaemus janeae, an electric knifefish species with a restricted distribution in the Amazon Basin. Monthly samples were collected from December 2020 to November 2021 in the Volta Grande stretch of the Xingu ...

Governing Transnational Commons: How International Treaties and Multi‐Stakeholder Organizations Shape Cooperation and Conflict

open access: yesJournal of Management Studies, EarlyView.
Abstract When common‐pool resources such as freshwater, clean air, and fisheries span national borders, the collective action problems encountered are particularly severe. This study explores the role of polycentric governance systems in overcoming these pressing problems, which frequently underlie global grand challenges. Integrating political economy
