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

Conservation 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)

Aquaculture 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

Conservation 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

Ecology 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 ...

Testing for concordance between predicted species richness, past prioritization, and marine protected area designations in the western Indian Ocean

Conservation Biology, Volume 38, Issue 4, August 2024.
Abstract Scientific advances in environmental data coverage and machine learning algorithms have improved the ability to make large‐scale predictions where data are missing. These advances allowed us to develop a spatially resolved proxy for predicting numbers of tropical nearshore marine taxa.

Relationship between two pathogens in an amphibian community that experienced mass mortalities

Conservation Biology, Volume 38, Issue 3, June 2024.
Abstract Because host species tend to harbor multiple parasitic species, coinfection in a host is common. The chytrid fungus Batrachochytrium dendrobatidis (Bd) and the viruses in the genus Ranavirus (Rv) are responsible for the decline of amphibians worldwide.
