Assessment of Small‐Meshed Gillnets for Sustainable Fisheries in the Chobe River, Namibia

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Small‐meshed gillnets are restricted by the regulatory framework of the Namibian Inland Fisheries Act of 2003. This is mainly because smaller meshed nets are presumably selective towards juveniles of the large‐growing cichlid species. Thus, the aim of this study was to assess the impacts of smaller meshed gillnets (<73 mm) on the fish stocks ...

Spatial Factors Outweigh Environmental Variables in Explaining Fish Beta Diversity Within A Massive Anthropogenically Homogenized Water‐Transfer Canal

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
In physically unobstructed and homogenized artificial ecosystems, dispersal limitation driven by geographic distance and unique hydraulic conditions replace environmental filtering as the primary deterministic process shaping diversity patterns. Furthermore, significant regulatory effects of food resources through trophic cascades reinforce this ...

The Structure of Vertebrate Antigen Receptor Repertoires: An Evolutionary Perspective

open access: yesImmunological Reviews, Volume 341, Issue 1, August 2026.
ABSTRACT In vertebrate adaptive immune systems, somatically diversified antigen receptors assume a central role in self/nonself discrimination. Attesting to the presence of a unique but unknown selective environment at early stages of vertebrate evolution, this facility emerged twice, in the ancestors of jawless and jawed vertebrates.
