Conservation benefits of a large marine protected area network that spans multiple ecosystems

open access: yesConservation Biology, Volume 39, Issue 4, August 2025.
Abstract Marine protected areas (MPAs) are widely implemented tools for long‐term ocean conservation and resource management. Assessments of MPA performance have largely focused on specific ecosystems individually and have rarely evaluated performance across multiple ecosystems either in an individual MPA or across an MPA network.

Time and Concentration Effects of Amino Acid Supplements on Stress Responses in the Gilthead Seabream (Sparus aurata)

open access: yesAquaculture Research, Volume 2025, Issue 1, 2025.
It has been reported that phenylalanine (Phe) or tyrosine (Tyr) supplementations significantly affect fish stress and welfare biomarkers. The objective of this study was to determine the amount of Phe/Tyr in the diet and feeding time necessary to mitigate stress. Seabreams (Sparus aurata) were stocked at 5 kg m−3 in 500 L tanks.

Evaluating the influence of marine protected areas on surf zone fish

open access: yesConservation Biology, Volume 38, Issue 6, December 2024.
Abstract Marine protected areas (MPAs) globally serve conservation and fisheries management goals, generating positive effects in some marine ecosystems. Surf zones and sandy beaches, critical ecotones bridging land and sea, play a pivotal role in the life cycles of numerous fish species and serve as prime areas for subsistence and recreational fishing.

Meristic co‐evolution and genomic co‐localization of lateral line scales and vertebrae in Central American cichlid fishes

open access: yesEcology and Evolution, Volume 14, Issue 9, September 2024.
We dissect the co‐evolution and genetic architecture of lateral line scale counts and vertebrae numbers in Neotropical Heroine cichlids. Our phylogenetic comparative analyses recovered a positive correlation between these two traits. Furthermore, our qualitative traits locus (QTL) analyses identified significant genomic co‐localized associations for ...
