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.

Ecologic Traits Analysis for Identifying Rodent Hosts for Arenavirus and Hepacivirus in the Americas

open access: yesBiotropica, Volume 57, Issue 6, November 2025.
Over half of emerging human pathogens originate from wildlife, with rodents serving as key zoonotic hosts. This study used ecological trait‐based models to identify rodent traits associated with arenavirus and hepacivirus infections and detect potential host species across the Americas, our models achieve high predictive accuracy (AUC = 0.92–0.96).

Great minds map alike: Citizen and expert distribution models of schistosome snail hosts in rural west Uganda

open access: yesEcological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.
Citizen scientists and an expert jointly monitor Biomphalaria snails (the intermediate host of Schistosoma mansoni) in rural areas of southwest Uganda, generating over 4500 georeferenced records. By comparing expert‐ and citizen‐based distribution models under perfect and imperfect detection, we demonstrate that site type and NDVI consistently ...

Foliar spectral signatures reveal adaptive divergence in live oaks (Quercus section Virentes) across species and environmental niches

open access: yesNew Phytologist, Volume 248, Issue 1, Page 370-388, October 2025.
Summary Genomic tools have advanced our understanding of species and population structure, but distinguishing neutral from adaptive evolution remains challenging due to limited methods for measuring a broad spectrum of phenotypic traits. We used spectroscopic data from preserved leaves to test for adaptive divergence among populations of live oaks ...
