THE AMPHIBIAN TREE OF LIFE
TLDR
A new taxonomy of living amphibians is proposed to correct the deficiencies of the old one, based on the largest phylogenetic analysis of living Amphibia so far accomplished, and many subsidiary taxa are demonstrated to be nonmonophyletic. Expand
SYSTEMATIC REVIEW OF THE FROG FAMILY HYLIDAE, WITH SPECIAL REFERENCE TO HYLINAE: PHYLOGENETIC ANALYSIS AND TAXONOMIC REVISION
TLDR
The present analysis indicates that Hemiphractinae are not related to the other three hylid subfamilies and are therefore removed from the family and tentatively considered a subfamily of the paraphyletic Leptodactylidae. Expand
PHYLOGENETIC SYSTEMATICS OF DART-POISON FROGS AND THEIR RELATIVES (AMPHIBIA: ATHESPHATANURA: DENDROBATIDAE)
TLDR
A new, monophyletic taxonomy for dendrobatids is proposed, recognizing the inclusive clade as a superfamily (Dendrobatoidea) composed of two families (one of which is new), six subfamilies (three new), and 16 genera (four new). Expand
Molecular systematics of terraranas (Anura: Brachycephaloidea) with an assessment of the effects of alignment and optimality criteria.
TLDR
The optimal tree-alignment indicates that insertions and deletions occurred in twice as many aligned positions as implied by the optimal similarity-Alignment, confirming previous findings that sequence turnover through insertion and deletion events plays a greater role in molecular evolution than indicated by similarity-alignments. Expand
The conservation status of the world's reptiles
TLDR
The results provide the first analysis of the global conservation status and distribution patterns of reptiles and the threats affecting them, highlighting conservation priorities and knowledge gaps which need to be addressed urgently to ensure the continued survival of the world’s reptiles. Expand
Total Evidence, Sequence Alignment, Evolution of Polychrotid Lizards, and a Reclassification of the Iguania (Squamata: Iguania)
TLDR
The Polychrotidae is found not to be monophyletic, containing instead the Corytophanidae as the sister taxon of Anolis plus Polychrus, and the Iguania is reformulated. Expand
A CONSIDERATION OF EPISTEMOLOGY IN SYSTEMATIC BIOLOGY, WITH SPECIAL REFERENCE TO SPECIES
TLDR
In this view, ontology is the result of reconciliation of theoretical expectations and lines of operational evidence that provides a general picture of the world and illuminates the limitations of particular discovery operations. Expand
Phylogenetics of the lizard genus Tropidurus (Squamata: Tropiduridae: Tropidurinae): direct optimization, descriptive efficiency, and sensitivity analysis of congruence between molecular data and
TLDR
A sensitivity analysis demonstrated that equal weighting of indels, transitions, transversions, and morphological change provided the most congruent solution between the molecular and the morphological data partitions. Expand
