Hydropower Regulation of Xingu River Discharge Structures Heterogeneous, Sector‐Specific Responses in Pacu Fisheries Along the River Continuum

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Hydroelectric dams are common in Amazonian tributaries under federal environmental licensing that requires long‐term fisheries monitoring. This study evaluated three fishing systems targeting “pacu” species (Serrasalmidae) in the Xingu River before, during, and after construction of the Belo Monte dam (2012–2023) across four river sectors ...

Growth and Overfishing Indicators Applied to the Protandrous Hermaphrodite Fat Snook (Centropomus parallelus) in the South Atlantic

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The fat snook Centropomus parallelus is a protandrous hermaphrodite teleost of artisanal and recreational value in the South Atlantic, vulnerable to fishing pressure and size‐selective gears. We evaluated exploitation status using size and age based overfishing indicators from recreational fishing championships and artisanal landings along the

A global perspective on the annual cycles of whimbrels

open access: yesIbis, EarlyView.
Comparative analyses are central to understanding broad‐scale patterns in avian ecology, yet their application is often constrained by fragmented and uneven data availability. Recent advances in tracking technology have generated unprecedented insights into shorebird movements, resulting in numerous studies on single populations or flyways.

Explaining Differentiated Policy Implementation of EU Animal Welfare Regulations

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract Farm animal welfare has emerged as a growing policy subsystem within the European Union's (EU) Common Agricultural Policy. However, despite a harmonized EU framework, member states differ substantially in how they implement EU directives on farm animal welfare.

Early‐life pathways to inequalities in child mental health: evidence from eight birth cohorts

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background Socioeconomic inequalities in children's emotional and behavioural problems are already present at school entry. We examined associations between early‐life socioeconomic conditions and children's externalising and internalising problems and assessed whether early‐life risk factors mediated these associations.

DNA barcoding reveals the presence of Whitson's grenadier, Macrourus whitsoni, in sub‐Antarctic waters of South Georgia, Southern Ocean

open access: yesJournal of Fish Biology, EarlyView.
Abstract Macrourid species constitute the main bycatch in Southern Ocean toothfish longline fisheries. We report the first confirmed record of Whitson's grenadier, Macrourus whitsoni, in the South Georgia toothfish fishery. Mitochondrial cox1 DNA barcoding confirmed its presence in bycatch samples collected around South Georgia and the northern South ...

Embryonic and larval development of the endangered Chiapas killifish Tlaloc hildebrandi (Cyprinodontiformes: Profundulidae)

open access: yesJournal of Fish Biology, EarlyView.
Abstract The early ontogeny of endemic freshwater fishes provides essential baseline biological information for conservation and management, particularly in species with restricted distributions and high vulnerability to habitat degradation, environmental change and population decline. This study presents the first detailed description of embryonic and
