Salt in the Wound: Assessing Pathogen Susceptibility in Amphibian Populations Across a Gradient of Salt Pollution

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The survival function of nine larval wood frog populations and their viral loads when exposed to FV3. The populations were collected as eggs from a range of salt‐polluted ponds. Viral load data are means ±1 SE. The populations are ordered in terms of the saltiness of their natal ponds.

Meteorology and geography, more than biological traits, drive variation in frog phenology across decades

open access: yesEcology, Volume 107, Issue 5, May 2026.
Abstract The fate of a species is a function of interacting environmental and biological processes. Disentangling the roles and interactions of such processes can elucidate the breadth of possible responses to global change, for instance, the potential for phenotypic plasticity or trait evolution to rescue populations from climate change.

Effects of temperature on growth, development, and survival of amphibian larvae: macroecological and evolutionary patterns

open access: yesAnais da Academia Brasileira de Ciências
Temperature affects the rate of biochemical and physiological processes in amphibians, influencing metamorphic traits. Temperature patterns, as those observed in latitudinal and altitudinal clines, may impose different challenges on amphibians depending ...

Artificial sensory and motor nervous systems enabled by bioinspired nanowire heterostructure synapse

open access: yesInfoMat, Volume 8, Issue 5, May 2026.
A p‐i‐n heterostructured junction synaptic transistor was fabricated, composed of poly(3‐hexylthiophene‐2,5‐diyl) nanowire thin‐film/poly(methyl methacrylate)/ZnO nanowires (PZJ STs), which can emulate biological sensory and motor nervous systems.

Reversão sexual de rã-touro (Rana catesbeiana) com hormônio masculinizante misturado à ração de girinos Sexual reversion of bullfrog with masculinizing hormone added to the tadpole ration

open access: yesRevista Brasileira de Zootecnia, 2001
Este trabalho consistiu em testar a eficiência de um hormônio masculinizante (17beta-hidróxi-17-metil-andróxi-4-en-3-ona) na reversão sexual de girinos de rã-touro (Rana catesbeiana).

Adjoint affine fusion and tadpoles

open access: yes, 2016
We study affine fusion with the adjoint representation. For simple Lie algebras, elementary and universal formulas determine the decomposition of a tensor product of an integrable highest-weight representation with the adjoint representation.

Scale of herpetofauna mitigation translocation in British Columbia, Canada

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
Mitigation translocation is widely used across British Columbia to move amphibians and reptiles away from development. Reviewing permits from 2019–2022, we found that more than 5 million individuals, mostly larval western toads, were relocated. Yet almost no monitoring occurs, leaving outcomes unknown.

Efeito do fotoperíodo sobre o desenvolvimento de girinos de rã-touro (Rana catesbeiana Shaw, 1802) Effect of the photoperiod on bullfrog (Rana catesbeiana Shaw, 1802) tadpoles development

open access: yesRevista Brasileira de Zootecnia, 2004
O objetivo deste trabalho foi avaliar o efeito de diferentes fotoperíodos sobre o peso, comprimento e a metamorfose de girinos de rã-touro (Rana catesbeiana Shaw, 1802).

Radiographic evaluation of gastroliths in a group of 49 juvenile saltwater crocodiles (Crocodylus porosus) in the UK

open access: yesVeterinary Record, Volume 198, Issue 8, Page e343-e350, 18/25 April 2026.
Abstract Background Gastrolith ingestion is a known inherent behaviour in crocodiles. However, the interpretation of coelomic radiographs in crocodilians is challenging due to the limited informative literature in this field. Methods Dorsoventral coelomic radiographs of 49 juvenile saltwater crocodiles (Crocodylus porosus) were acquired twice, with an ...
