Wide variation in hydraulic safety margins across and within southern Amazon forests

Journal of Ecology, Volume 114, Issue 5, May 2026.
Site‐specific conditions and species identity were the main drivers of variation in Ψdry and HSM50 in southern Amazonian trees, but played a weaker role in explaining Ψ50. Ψpredawn strongly predicted HSM50. Across the Amazon, Ψ50_CWM and Ψdry_CWM became more negative with increasing MCWD, whereas HSM50_CWM showed no significant relationship with MCWD ...

Exploring ecohydrology through the lens of local fishers in the Bolivian Amazon

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract The natural flow regimes of Andean‐Amazon tributaries play a vital role in sustaining their rich biodiversity and productive local fisheries, but ongoing and proposed alteration of river flow regimes by large dams threatens to negatively impact river ecosystems. Despite its importance, our understanding of how hydrologic variability influences

Modelo de distribución geográfica del pez Coryphaena hippurus (Perciformes: Coryphaenidae) según el cambio climático en el Pacífico Oriental Tropical

Revista de Biología Tropical
Introducción: Coryphaena hippurus es una especie migratoria de interés comercial, que se encuentra en ambientes tropicales y subtropicales, prefiriendo zonas con un rango de temperatura entre 21 y 30 °C y salinidad cercana a 31 ppt. Aunque la tendencia poblacional del dorado es estable, la pesquería de este recurso está aumentando y ocupa importantes ...

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 ...

Indigenous peoples and local community reports of climate change impacts on biodiversity

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Climate change impacts on biodiversity have been primarily studied through ecological research methods, largely ignoring other knowledge systems. Indigenous and local knowledge systems include rich observations of changes in biodiversity that can inform climate change adaptation planning and environmental stewardship.

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

Conservation 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 ...

Extent of threats to marine fish from the online aquarium trade in the United States

Conservation Biology, Volume 40, Issue 1, February 2026.
The global marine aquarium hobby is a multibillion‐dollar industry, largely driven by demand from the United States. Much of this trade occurs online. We web scraped 4 major US‐based e‐commerce platforms selling marine aquarium fish to determine the retail price and source (wild capture, aquaculture, or both) of 13 families of ray‐finned marine fish ...
