Long-Term Changes in the Winter Diet of Common Dolphins Reflects Ecological Shifts and Bycatch Dynamics in the Bay of Biscay. [PDF]
Ecol EvolFirst study investigating temporal changes in the diet of the common dolphin (Delphinus delphis) in the Bay of Biscay between 1999 and 2019, we found that the diet of the common dolphin remained mainly composed of small energy‐rich fish species. However, we observed a shift in minor prey from upper slopes habitats to coastal waters reflecting a shift ...

Aquatic eDNA outperforms sedimentary eDNA for the detection of estuarine fish communities in subtropical coastal vegetated ecosystems. [PDF]
J Fish BiolAbstract In South Africa, mangrove forests and seagrass meadows often co‐occur in estuarine systems and in combination host rich, often endemic biodiversity. There is an urgent need to explore community diversity in coastal vegetated ecosystems, given the degrading effects of climate change and anthropogenic pressures.

Spatio-temporal assessment of nearshore fish communities in a temperate estuary using functional and community metrics for restoration and management. [PDF]
J Fish BiolAbstract Understanding the structure and function of estuarine fish communities is essential for guiding ecosystem‐based management and restoration. This study investigated long‐term patterns in fish community composition, abundance, species richness and estuarine use across 15 nearshore sites within three estuaries and the Isle of Wight, located in ...

Improving Whole Biodiversity Monitoring and Discovery With Environmental DNA Metagenomics. [PDF]
Mol Ecol ResourABSTRACT Environmental DNA (eDNA) metagenomics sequences all DNA molecules present in environmental samples and has the potential of identifying virtually any organism from which they are derived. However, due to unacceptable levels of false positives and negatives, this approach is underexplored as a tool for biodiversity monitoring across the tree of

The invasive twospot livebearer's biology, and its current and potential global distribution
Journal of Fish Biology, Volume 103, Issue 5, Page 854-863, November 2023., 2023 Abstract Poeciliids are widely recognized as successful invaders, possessing traits associated with invasion success. Native to Central America and south‐eastern Mexico, the twospot livebearer (Pseudoxiphophorus bimaculatus) is a species recently recognized as invasive in both Central and northern Mexico.

Threatened fish species in the Northeast Atlantic are functionally rare
Global Ecology and Biogeography, Volume 32, Issue 10, Page 1827-1845, October 2023., 2023 Abstract Aim The criteria used to define the International Union for Conservation of Nature (IUCN) Red List categories are essentially based on demographic parameters at the species level, but they do not integrate species' traits or their roles in ecosystems.

Introduced Spartina anglica modifies fish habitat in southern temperate succulent saltmarshes
Restoration Ecology, Volume 31, Issue 7, September 2023., 2023 Vegetation changes in saltmarsh habitat can influence fish assemblages and abundance. In Tasmania, Australia, mid‐latitude succulent saltmarsh communities have been invaded by the introduced tall grass, Spartina anglica. Eradication efforts have been ongoing since the 1990s with purported benefits for fish access to intertidal foraging grounds, but a ...

Aquaculture, Fish and Fisheries, Volume 3, Issue 3, Page 316-328, June 2023., 2023 This study reports for the first‐time potential predators and competitors that recruited and migrated to floating hapa nets during ocean nursery culture of sandfish juveniles reared in the Philippines. Results indicate that the presence of potential predators and competitors within the floating hapas negatively affected growth performance and survival ...

Journal of Applied Ecology, Volume 60, Issue 4, Page 638-649, April 2023., 2023 Our results suggest that sustained warming will likely reduce fish biomass in the Mediterranean Sea and shift community structure, requiring more conservative targets for fishery regulations. At the same time, protection from fishing will remain an important management tool even with future high‐water temperatures, and MPAs are expected to continue to ...
