BERGMANN'S RULE IN NONAVIAN REPTILES: TURTLES FOLLOW IT, LIZARDS AND SNAKES REVERSE IT
TLDR
This is the first study to document the converse to Bergmann's rule in any major animal group as well as the first to show Bergmann’s rule in a major group of ectotherms.
The complete mitochondrial genome of the enigmatic bigheaded turtle (Platysternon): description of unusual genomic features and the reconciliation of phylogenetic hypotheses based on mitochondrial
TLDR
This study robustly determines the phylogenetic placement of Platysternon and provides a well-resolved outline of major turtle lineages, while demonstrating the significantly greater resolving power of comparing large amounts of mt sequence over that of short fragments.
Comparative phylogeography of woodland reptiles in California: repeated patterns of cladogenesis and population expansion
TLDR
This work focuses on a group of squamate reptiles that share similar ecological requirements and generally occupy the same communities in the western USA, and finds significant congruence between the phylogeographies of E. multicarinata and L. zonata suggests that the succession of vicariance and dispersal events in these species progressed in concert.
New Chinese turtles: endangered or invalid? A reassessment of two species using mitochondrial DNA, allozyme electrophoresis and known‐locality specimens
TLDR
The phylogenetic and taxonomic validity of two new species of geoemydid turtles from China are tested and the available evidence is consistent with the hypothesis that the specimens represent polyphyletic, intergeneric hybrids.
Molecular phylogenetics of emydine turtles: taxonomic revision and the evolution of shell kinesis.
TLDR
Parsimony, paleontological evidence, and the multiple origins of shell kinesis in related turtle lineages (especially geoemydines) support the independent origin of plastral kinesIS.
Constraint shapes convergence in tetrodotoxin-resistant sodium channels of snakes
TLDR
It is demonstrated that constraints resulting from functional tradeoffs between ion channel function and toxin resistance led to predictable patterns of evolutionary convergence at the molecular level, suggesting that natural selection may be frequently constrained to produce similar genetic outcomes even when operating on independent lineages.
The evolutionary origins of beneficial alleles during the repeated adaptation of garter snakes to deadly prey
TLDR
The results demonstrate that adaptive evolution has occurred independently multiple times in garter snakes via the de novo acquisition of beneficial mutations.
Parallel Arms Races between Garter Snakes and Newts Involving Tetrodotoxin as the Phenotypic Interface of Coevolution
TLDR
The existence of apparent parallel arms races between species pairs of garter snakes and their toxic newt prey that indicate independent evolutionary origins of a key phenotype in the interface are reported.
