A combined genome-wide approach identifies a new potential candidate marker associated with the coat color sidedness in cattle [PDF]

open access: yes, 2019
Coat color is one of the most important phenotypic features in livestock breeds. Cinisara is a local cattle breed generally of uniform black color which occasionally presents a particular phenotype, with animals typically display a white band along their

Controlled Ghost Fishing: Effects of Soaking Times and Mesh Sizes on Catchability in Trammel Net Fisheries

open access: yesFisheries Management and Ecology, Volume 32, Issue 6, Page 405-417, December 2025.
ABSTRACT Trammel nets are used with extended soaking times to increase the catching efficiency for demersal fish in commercial fishing. Long soaking time causes deterioration or damage to species caught in the first days. Effects of soaking time were investigated with 36‐mm, 42‐mm, and 46‐mm mesh sizes soaked over 1, 3, 5, and 7 days on target, non ...

Unravelling Hidden Trophic Interactions Among Sea Urchin Juveniles and Macroinvertebrates by DNA Amplification

open access: yesMolecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Rocky reefs may shift between two distinct stable states: productive algal forests, characterised by high abundance and biodiversity of macrofauna, and impoverished barrens, dominated by overgrazing sea urchins. Barren states may persist despite the recovery of adult sea urchin predators, suggesting additional stabilising mechanisms.

Uncovering the Genetic Structure of European Anchovy Populations in Central and Western Mediterranean

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
This study used advanced genomic techniques to analyze population structure, genetic diversity, and environmental associations in European anchovies across the Western and Central Mediterranean and nearby Atlantic regions. Two main genetic clusters were identified, separated by the Almeria–Oran front, with significant associations found between genetic
