A phylogeny and revised classification of Squamata, including 4161 species of lizards and snakes
TL;DR: A new large-scale phylogeny of squamate reptiles is presented that includes new, resurrected, and modified subfamilies within gymnophthalmid and scincid lizards, and boid, colubrid, and lamprophiid snakes.
Journal ArticleDOI
Phylogenetic analyses reveal unexpected patterns in the evolution of reproductive modes in frogs
TL;DR: This work analyzes the evolution of anuran reproductive modes using comparative methods on a phylogeny and matched life‐history database of 720 species, finding significant associations between terrestrial reproduction and reduced clutch size, larger egg size, reduced adult size, parental care, and occurrence in wetter and warmer regions.
Journal ArticleDOI
Fossil-based comparative analyses reveal ancient marine ancestry erased by extinction in ray-finned fishes
TL;DR: This study highlights the importance of including fossils in comparative analyses, showing that freshwaters have played a role as refuges for ancient fish lineages, a signal erased by extinction in extant-only phylogenies.
Journal ArticleDOI
Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

TL;DR: The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa.
Journal ArticleDOI
Systematics of the blindsnakes (Serpentes: Scolecophidia: Typhlopoidea) based on molecular and morphological evidence.
TL;DR: A new molecular phylogenetic analysis including 95 of the 275 currently recognized, extant typhlopoids, incorporating both nuclear and mitochondrial loci is presented, and a revised classification for Typhlopoidea is generated.
