Multidisciplinary Evaluation of a 10‐Year Restoration Program for Two Endangered Atlantic Salmon (Salmo salar) Populations

open access: yesEvolutionary Applications, Volume 19, Issue 7, July 2026.
ABSTRACT Supportive breeding programs are widely implemented to counteract demographic collapse in threatened populations. Their long‐term success, however, depends on maintaining genetic diversity while ensuring that released individuals contribute effectively to wild populations.

Scaling non-linearities at circular crested weirs: physical modelling & challenges

open access: yes
Liquid overflowing over rounded weirs experiences a rapidly accelerating flow region with converging streamlines near the crest. Depending upon the discharge, radius of curvature and weir height, the overflow nappe may be attached or detached. Herein, detailed physical modelling was conducted under carefully controlled conditions with a circular weir ...

Geometrically simple linear weirs using circular quadrants

open access: yes, 1991
A detailed theoretical analysis of flow through a quadrant plate weir is made in the light of the generalized theory of proportional weirs, using a numerical optimization procedure.

Wasta and Gender Inequality in the Workplace: A Conceptual Framework for Social Network Influence in the Middle East and North Africa

open access: yesGender, Work &Organization, Volume 33, Issue 4, Page 1245-1258, July 2026.
ABSTRACT Although organizational social networks are extensively researched, the gendered implications of informal networks embedded in distinctive socio‐cultural contexts remains underexplored. This conceptual paper focuses on wasta, a pervasive form of informal network and social capital in the Middle East and North Africa (MENA) region, which ...

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

open access: yesIbis, Volume 168, Issue 3, Page 972-984, July 2026.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Killer Whales in the Central Tropical Pacific: Occurrence, Resightings, Morphology, and Acoustics

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Compared to their well‐studied coastal temperate counterparts, killer whales (Orcinus orca) in tropical‐subtropical and oceanic areas are under‐documented. We used sighting, photo‐identification, and acoustic data of killer whales in the central tropical Pacific (CTP), collected from multiple platforms between 2002 and 2023, to assess their ...
