FOSSIL SALAMANDERS AND SALAMANDER ORIGINS [PDF]

open access: yesAmerican Zoologist, 1965
Recent (mostly unpublished) work indicates that the present classification of salamanders needs modification. The fossil record of salamanders has been markedly improved recently, and tends to support these conclusions, but does not offer any clues to the origin of salamanders or of the Lissamphibia as a whole. The structure of the sirenid salamanders,

Biogeographic history of Palearctic caudates revealed by a critical appraisal of their fossil record quality and spatio-temporal distribution

open access: yesRoyal Society Open Science, 2022
The disjunct geographical range of many lineages of caudates points to a complex evolutionary and biogeographic history that cannot be disentangled by only considering the present-day distribution of salamander biodiversity.

When no color pattern is available: Application of double observer methods to estimate population size of the Alpine salamander

open access: yesArctic, Antarctic, and Alpine Research, 2021
Monitoring wild populations is an essential tool to assess the conservation status and the ecological requirements of a species. Capture–mark–recapture (CMR), based on individual recognition, is the most commonly used and most effective technique ...

Non-tuberculous mycobacterial disease associated with Mycobacterium montefiorense in salamanders

open access: yesFrontiers in Veterinary Science, 2023
IntroductionMycobacterium montefiorense is one of the causes of non-tuberculous mycobacterial infections in moray eels and salamanders. Although M. montefiorense infection could be a threat to salamanders, little information is available regarding this ...

A Triassic stem-salamander from Kyrgyzstan and the origin of salamanders [PDF]

open access: yesProceedings of the National Academy of Sciences, 2020
Significance The origin of modern amphibians remains controversial, and especially the fossil record of salamanders remains poor. Their tiny, feeble skeletons are rarely preserved in rocks of the early Mesozoic era, the time frame in which they are believed to have originated.

A Midsummer Night’s Diet: Snapshot on Trophic Strategy of the Alpine Salamander, Salamandra atra

open access: yesDiversity, 2020
Information on the trophic ecology of the Alpine salamander, Salamandra atra, is scattered and anecdotal. We studied for the first time the trophic niche and prey availability of a population from an area located in Italian Dolomites during the first ...

Palatal morphology predicts the paleobiology of early salamanders

open access: yeseLife, 2022
Ecological preferences and life history strategies have enormous impacts on the evolution and phenotypic diversity of salamanders, but the yet established reliable ecological indicators from bony skeletons hinder investigations into the paleobiology of ...
