Effect of feeding barbel larvae (Barbus barbus (L, 1758)) Artemia sp. nauplii enriched with PUFAs on their growth and survival rate, blood composition, alimentary tract histological structure and body chemical composition

open access: yesAquaculture Reports, 2020
This study analysed the effect of feeding a freshwater fish, barbel (Barbus barbus), with Artemia sp. enriched with polyunsaturated fatty acids (PUFA). Barbel larvae were divided into two groups, which received a daily dose of nauplii at 50 % of the fish

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

Landscape‐Driven Isolation Among, but High Genetic Diversity Within, Peripheral Populations of a Threatened Frog

open access: yesDiversity and Distributions, Volume 32, Issue 2, February 2026.
ABSTRACT Aim Many amphibians are experiencing declines, which are exacerbated for populations near range edges. To inform conservation strategies, we sampled sites of Blanchard's Cricket Frog (Acris blanchardi) at the northern periphery of their range to determine if modern declines are associated with genetic factors, delineate management units, and ...
