Amphibians.
Wake DB and Koo MS. Curr Biol 2018. PMID 30399342 Free article.
Since the dawn of history, amphibians have been a part of human culture. Western Europeans built fires for cooking and warmth, adding large logs as needed. ...In general, amphibians are seen as benign and harmless, even helpful as creatures that devour harmful insects and serve as an alternative food source. ...

Clinical pathology of amphibians: a review.
Forzán MJ, et al. Vet Clin Pathol 2017 - Review. PMID 28195641
Health evaluation of amphibians, free-living or captive, can benefit from employing the tools of clinical pathology, something that is commonly used in veterinary medicine of other vertebrates. ...

Biological Scaling Problems and Solutions in Amphibians.
Levy DL and Heald R. Cold Spring Harb Perspect Biol 2015 - Review. PMID 26261280 Free PMC article.
Amphibians populate some of the extremes in biological size and have provided insight into scaling mechanisms, upper and lower size limits, and their physiological significance. Body size variation is a widespread evolutionary tactic among amphibians, with miniaturization frequently correlating with direct development that occurs without a tadpole stage. ...

Fetal adaptations for viviparity in amphibians.
Wake MH. J Morphol 2015. PMID 24643944
Live-bearing has evolved in all three orders of amphibians--frogs, salamanders, and caecilians. Developing young may be either yolk dependent, or maternal nutrients may be supplied after yolk is resorbed, depending on the species. ...

Spatial Biodiversity Patterns of Madagascar's Amphibians and Reptiles.
Brown JL, et al. PLoS One 2016. PMID 26735688 Free PMC article.
A high proportion of clades and subclades of both amphibians and reptiles have a peak of local endemism in the topographically and bioclimatically diverse northern geographic regions. ...Range filling, i.e., the amount of suitable habitat occupied by a species, is less expressed in amphibians than in reptiles, possibly reflecting their lower dispersal capacity. ...

Ageing in amphibians.
Kara TC. Gerontology 1994 - Review. PMID 7926854
Increase in cross-linking of collagen, accumulation of age pigments (lipofuscin and melanin), decrease in metabolism and loss of immunocompetence are ageing phenomena common to both amphibians and mammals. On the other hand, persistence of neurogenesis and myogenesis, continuance of oogenesis beyond adult life and polyphyodonty are some of the features peculiar to ageing in amphibians. ...

Caecilians
Wilkinson M. Curr Biol 2012. PMID 22974987 Free article.
Cell cycles during early steps of amphibian embryogenesis: A review
Desnitskiy AG. Biosystems 2018 - Review. PMID 30240720
However, many amphibians (including the basal species) are characterized by large, yolky, and slowly cleaving eggs with very short series of synchronous divisions. ...

Amphibian immunity-stress, disease, and climate change
Rollins-Smith LA. Dev Comp Immunol 2017 - Review. PMID 27387153
Amphibians are facing historically unprecedented environmental stress due to climate change that will involve unpredictable temperature and rainfall regimes and possible nutritional deficits due to extremes of temperature and drought. At the same time, amphibians in all parts of the world are experiencing unprecedented declines due to the emerging diseases, chytridiomycosis (caused by Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans) and ranavirus diseases due to viruses of the genus Ranavirus in the family Iridoviridae. ...
