Many roads to reservoirs? How susceptibility and shedding shape host competence in amphibians

Functional Ecology, Volume 40, Issue 3, Page 585-598, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Host competence—the ability to acquire, harbour and transmit infections—drives pathogen spread and persistence in multi‐host communities. Evaluating species‐specific competence is critical for predicting transmission, particularly for generalist fungal pathogens like ...

Tracking viral particles in the intestinal contents of the American bullfrog, Lithobates catesbeianus, by Transmission Electron Microscopy

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2014
Feces are an important viral agent elimination route for infected carrier animals and in aquatic organisms these pathogenic agents can very rapidly propagate due to the habitation environment. The objective of this work is to track viral particles in the

Estimating spatially varying occupancy trends for multi‐scale conservation: An amphibian case study in the midwestern United States

Journal of Applied Ecology, Volume 63, Issue 3, March 2026.
Our spatial modelling approach allows practitioners to estimate trends across multiple spatial scales to inform local and regional management priorities, particularly when summarizing trends within key areal units used for conservation planning. Our framework can be used to identify hotspots of decline across multiple sympatric species for targeted ...

Primeiro relato de Lernaea cyprinacea (Copepoda: Lernaeidae) em girinos e rãs recém-metamorfoseadas em populações selvagens de Lithobates catesbeianus (Anura: Ranidae) na Argentina

Phyllomedusa: Journal of Herpetology, 2016
Lernaea cyprinacea é um copépode ectoparasita que pode causar a morte do hospedeiro devido às hemorragias, ulcerações e infecções secundárias que provoca. Lernaea cyprinacea está amplamente distribuída na Argentina.

Policy Recommendation on the Restriction on Amphibian Trade Toward the Republic of Korea

Frontiers in Environmental Science, 2020
Amphibian diseases and invasive amphibian species are both generally introduced through the wildlife trade, either for human consumption or for the pet trade. However, adequate regulations can prevent such introductions.

Aquatic Biodiversity of the Pampa Biome: Insights From a Scientometric and Systematic Perspective

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT The Pampa biome, in South America, covers parts of Brazil, Uruguay, and Argentina. Its main characteristic is the predominance of grassland areas. The Pampa biome supports high biological diversity and a wide variety of ecosystems. In this study, we provide a comprehensive overview of biodiversity studies focusing on freshwater ecosystems of ...

Changes in morphology over time due to denaturing agents in an ethanol and camphor solution [PDF]

Natural History Collections and Museomics
The ethanol collections of the Africamuseum require an approved denaturing agent, that can be used to top-up containers in which, historically, camphor-denatured ethanol has been used.

Simulated soundscapes and transfer learning boost the performance of acoustic classifiers under data scarcity

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 322-338, February 2026.
Abstract The biodiversity crisis necessitates spatially extensive methods to monitor multiple taxonomic groups for evidence of change in response to evolving environmental conditions. Programs that combine passive acoustic monitoring and machine learning are increasingly used to meet this need. These methods require large, annotated datasets, which are
