Glomerular permeability in the bullfrog Rana catesbeiana. [PDF]
The Journal of cell biology, 1978 Filtration studies suggest similar size pores in the glomerular filters of mammals and amphibians. However, the glomerular wall in the bullfrog exhibits several structural features not found in mammals. The subendothelial space of the basement membrane is often greatly enlarged and infiltrated by cellular elements.

Journal of Neuroendocrinology, Volume 37, Issue 9, September 2025.The corticotropin‐releasing factor (CRF) system plays a key role in centrally regulating thyroid hormone (TH) synthesis in non‐mammalian vertebrates, but interactions between THs and the CRF system remain poorly understood in fish. Here, we report that THs directly affect transcription of several CRF system components across different hypophysiotropic ...

Xenopus laevis and Emerging Amphibian Pathogens in Chile [PDF]
, 2016 Amphibians face an extinction crisis with no precedence. Two emerging infectious diseases, ranaviral disease caused by viruses within the genus Ranavirus and chytridiomycosis due to Batrachochytrium dendrobatidis (Bd), have been linked with amphibian ...

Non‐Native Species in Aquaculture: Burgeoning Production and Environmental Sustainability Risks
Reviews in Aquaculture, Volume 17, Issue 3, June 2025.ABSTRACT Rising global food demands and technological advancements have led to unprecedented growth in the aquaculture industry. This rapid expansion has facilitated the translocation of species beyond their native ranges. While farming non‐native species boosts global food supply, it also poses environmental and socio‐economic risks when escapees ...

eDNA‐Based Detection of Invasive Crayfish and Crayfish Plague in Estonia
Environmental DNA, Volume 7, Issue 3, May–June 2025.Our study explored the potential of integrating the eDNA approach into ongoing annual monitoring programs for invasive crayfish species and A. astaci. Crayfish eDNA was detected in 9 out of 14 water bodies where presence was confirmed by trapping, yielding 64% detection efficiency. eDNA from A.
