Size and shape in ontogeny and phylogeny
TLDR
A quantitative method for describing how heterochronic changes in ontogeny relate to phyletic trends is presented, and a greatly simplified and logical scheme of classification is obtained that will be particularly useful in studying the data of paleontology and comparative morphology.
Amphibian Declines: Judging Stability, Persistence, and Susceptibility of Populations to Local and Global Extinctions
TLDR
It is suggested that many amphibian populations may be unable to recolonize areas after local extinction, due to the physiological constraints, relatively low mobility, and site fidelity of amphibians.
Miniaturization of Body Size: Organismal Consequences and Evolutionary Significance
TLDR
Evaluation of causes and consequences of miniaturization should consider obvious feattires of physical size as well as less obvious, but biologically important, features such as genome and cell size.
Morphological homoplasy, life history evolution, and historical biogeography of plethodontid salamanders inferred from complete mitochondrial genomes.
TLDR
The authors' phylogenetic analyses yielded congruent trees that contrast with the traditional morphology-based taxonomy; the monophyly of three of four major groups is rejected and they suggest surprising evolutionary lability in traits previously interpreted to be conservative.
Phylogenomics reveals rapid, simultaneous diversification of three major clades of Gondwanan frogs at the Cretaceous–Paleogene boundary
TLDR
It is found that ∼88% of living frogs originated from three principal lineages that arose at the end of the Mesozoic, coincident with the Cretaceous–Paleogene mass extinction event that decimated nonavian dinosaurs 66 Mya.
Coincident mass extirpation of neotropical amphibians with the emergence of the infectious fungal pathogen Batrachochytrium dendrobatidis
TLDR
A noninvasive PCR sampling technique is described that can be used to screen museum specimens from other amphibian decline sites around the world and finds evidence of a historical “Bd epidemic wave” that began in Mexico and subsequently spread to Central America.
Rapid diversification and dispersal during periods of global warming by plethodontid salamanders
TLDR
Salamanders underwent rapid episodes of diversification and dispersal that coincided with major global warming events during the late Cretaceous and again during the Paleocene–Eocene thermal optimum, contemporaneously with similar phenomena in angiosperms, arthropods, birds, and mammals.
Phylogeographic Lineages and Species Comparisons in Conservation Analyses: A Case Study of California Herpetofauna
TLDR
This work compared spatial patterns of endemism and conservation value for 22 species of Californian amphibians and reptiles with the 75 phylogeographic lineages that they contain to assess the extent to which the genetic component of diversity affects conservation assessments.
