The Anatomical Record, Volume 308, Issue 11, Page 3053-3062, November 2025.Abstract Most carnivorans and all modern felids have ossified bacula; however, no machairodont baculum has ever been identified. This is true despite the many fairly complete skeletons found around the world of several sabertooth taxa. Although the bacula of modern felids are much smaller than those of canoids (even the least weasel's baculum is longer

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.

The Metamorphosis of Amphibian Toxicogenomics [PDF]
, 2012 Amphibians are important vertebrates in toxicology often representing both aquatic and terrestrial forms within the life history of the same species. Of the thousands of species, only two have substantial genomics resources: the recently published genome

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 ...

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 ...
