People and Nature, Volume 8, Issue 3, Page 782-796, March 2026.Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental

Dietary resilience of coral reef fishes to habitat degradation
Journal of Animal Ecology, Volume 95, Issue 3, Page 397-417, March 2026.Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Validez de la ecuación binómica de Forchheimer en flujo convergente en un medio poroso
Ingeniería Hidráulica y Ambiental, 2012 El flujo en medios porosos a través de contornos paralelos ha sido ampliamente investigado en las últimas cinco décadas. Pero son pocos los estudios con permeámetros convergentes, menos aún cuando el flujo no sigue la ley de Darcy.

Molecular Ecology, Volume 35, Issue 3, February 2026.ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

Key role for inhibins in effective T cell activation, migration and Th17 differentiation
FEBS Open Bio, Volume 16, Issue 1, Page 79-89, January 2026.Activins/inhibins modulate immune responses. Here, we show that inhibins can be produced very early after T cell activation and can act in an autocrine way, favoring Th1 versus Th17 differentiation and CCL19/CCL21 mediated migration. Recombinant inhibin A can restore the Th1/Th17 balance, highlighting the role of inhibins as key regulators of T cell ...

Journal of Environmental Quality, Volume 55, Issue 1, January/February 2026.Abstract Urbanization generates significant amounts of sewage sludge (SS), with relatively high concentrations of plant nutrients such as phosphorus (P). When biochemically stabilized by composting, SS (composted sewage sludge [CSW]) can serve as a sustainable P source in agriculture, supporting a circular economy and reducing agriculture's dependence ...
