Spatial Scale Modulates the Effect of Habitat Amount on Diversity Patterns of Arachnid Assemblages Across Different Brazilian Ecosystems

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim We evaluated how native vegetation cover influences the diversity of arachnid assemblages across multiple spatial scales in major Brazilian ecosystems. Location Brazil (Amazon and Atlantic rainforests, Cerrado savanna and Caatinga dry forest). Taxon Arachnida (Opiliones, Pseudoscorpiones and Scorpiones). Methods We sampled arachnids at 120

Melanism in salamanders: effects of insularity, sex and size on dorsal colouration in Salamandra salamandra

Journal of Zoology, Volume 329, Issue 4, Page 340-352, August 2026.
In this study we tested the effects of insularity on amphibian colouration using the fire salamander as a model system. Although increased melanism was not a consistent pattern across all islands, salamanders from one island exhibited higher proportions of black pigmentation than mainland populations, while insular populations overall showed reduced ...

Environmental detection of the amphibian chytrid fungus in water bodies is associated with host infection along a deforestation gradient

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Linking environmental pathogen detection with host infection patterns can improve surveillance of diseases involving environmental transmission, particularly where direct host sampling is logistically challenging. This approach enables the identification of areas of elevated transmission risk and supports targeted monitoring and management under ...
