Vulnerability of tropical fish communities across depth in the central Indian Ocean

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Coral reefs and their fish communities below scuba diving depth (>30 m), in mesophotic coral ecosystems (MCEs) (∼30–150 m), in rariphotic (150–300 m), and in upper bathyal waters (300–500 m) are often underexplored, especially in the Indian Ocean.

Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Inclusive Climate Action: A Scoping Review on the Representation and Inclusion of People With Intellectual Disability in Climate Change Research

open access: yesBritish Journal of Learning Disabilities, Volume 53, Issue 3, Page 428-445, September 2025.
ABSTRACT Background Climate change disproportionally affects people with intellectual disability. Despite this, people with intellectual disability are rarely included in conversations about just environmental futures. Methods Using PRISMA‐ScR guidelines, this scoping review maps the academic literature surrounding intellectual disability and climate ...

Potential for synergistic conservation through area‐based strategies

open access: yesConservation Biology, Volume 39, Issue 4, August 2025.
Abstract The ongoing biodiversity crisis has raised concerns about the effectiveness of area‐based conservation (ABC) strategies for achieving positive biodiversity outcomes. In riverine ecosystems, the linear habitat structure of fishes introduces uncertainty into the synergistic conservation potential of ABC.
