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

open access: yesFunctional 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 ...

Frog community responses to recent American bullfrog invasions

open access: yesCurrent Zoology, 2011
Native species may decline quickly when confronted with an exotic species to which they are not adapted. The extent of decline may depend on the abundance of an invader and the length of time since it first arrived in the community (residence time), and ...

Frog‐biting midges and mosquitoes: Comparative insights from the Oriental and Sino‐Japanese regions

open access: yesEntomological Science, Volume 29, Issue 1, March 2026.
This review synthetizes current knowledge of frog‐biting mosquitoes and midges in the Oriental region and Japan, revealing strong geographic biases in research despite shared amphibian lineages. We highlight key knowledge gaps to guide future studies. Abstract Frog‐biting mosquitoes (Culicidae) and midges (Corethrellidae) are old hematophagous lineages
