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

open access: yesJournal 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

open access: yesJournal 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 ...

Landscape change and conservation priorities: Mexican herpetofaunal perspectives at local and regional scales Cambios en el paisaje y prioridades de conservación: una perspectiva herpetofaunística mexicana a escalas local y regional

open access: yesRevista Mexicana de Biodiversidad, 2009
Few studies have demonstrated historical human impact on biodiversity at local and regional scales, largely due to lack of baseline information and long term monitoring for most taxa.

Survival and Behavior of Amphibians in a Seasonally Flooded Tropical Forest

open access: yesBiotropica, Volume 58, Issue 4, July 2026.
How do tropical amphibians survive seasonal flooding? A three‐year capture–mark–recapture study in Costa Rica revealed species‐specific responses to flood events, with flooding reducing apparent survival in some species while others persisted through behavioral adaptations and use of arboreal refugia.

Morphological and genetic differentiation among Chilean populations of Bufo spinulosus (Anura: Bufonidae) Diferenciación morfológica y genética entre poblaciones chilenas de Bufo spinulosus (Anura: Bufonidae)

open access: yesRevista Chilena de Historia Natural, 2004
Bufo spinulosus has a wide and fragmented range distribution in Chile (18° to 33° S) along altitudinal and latitudinal gradients. Genetic variation was estimated using RAPD (Random Amplified Polymorphic DNA) markers in 10 populations from ...

How vulnerable are amphibians to climate change? A mechanistic perspective

open access: yesFunctional Ecology, Volume 40, Issue 6, Page 1550-1560, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Amphibians are frequently identified as highly vulnerable to climate change, yet the mechanisms driving this sensitivity remain uncertain. Approaches that explicitly link physiological mechanisms to environmental variation provide powerful tools for forecasting climate ...
