TL;DR: A phylogenetic tree shows that crown clade Placentalia and placental orders originated after the K-Pg boundary, but phenomic signals overturn molecular signals to show Sundatheria (Dermoptera + Scandentia) as the sister taxon of Primates, a close link between Proboscidea and Sirenia (sea cows), and the monophyly of echolocating Chiroptera (bats).
Journal ArticleDOI
Trophic structure in a large assemblage of phyllostomid bats in Panama
TL;DR: It is shown that the trophic structure of the local contemporary assemblage of phyllostomids is largely conservative with respect to traceable ancestral habits, strongly suggesting that overall trophics structure was likely determined historically.
Journal ArticleDOI
Bat Systematics in the Light of Unconstrained Analyses of a Comprehensive Molecular Supermatrix
Lucila Inés Amador,R. Leticia Moyers Arévalo,Francisca C. Almeida,Santiago A. Catalano,Santiago A. Catalano,Norberto P. Giannini,Norberto P. Giannini,Norberto P. Giannini +7 more
TL;DR: A large-scale phylogeny of bats based on unconstrained searches for a data matrix of 804 non-chimeric, taxonomically updated bat terminals yielded a highly resolved, variously supported phylogeny that recovered the majority of currently recognized clades at all levels of the chiropteran tree.
Journal ArticleDOI
Paleogene equatorial penguins challenge the proposed relationship between biogeography, diversity, and Cenozoic climate change
Julia A. Clarke,Daniel T. Ksepka,Marcelo Stucchi,Mario Urbina,Norberto P. Giannini,Norberto P. Giannini,Sara Bertelli,Sara Bertelli,Yanina Narváez,Clint A. Boyd +9 more
TL;DR: The most comprehensive phylogenetic analysis of Sphenisciformes to date, combining morphological and molecular data, places the new species outside the extant penguin radiation (crown clade: Speniscidae) and supports two separate dispersals to equatorial regions during greenhouse earth conditions.
Journal ArticleDOI
Phylogenetic morphometrics (I): the use of landmark data in a phylogenetic framework
TL;DR: A method for the direct use of aligned landmark data (2D or 3D coordinates of comparable points) in phylogenetic analysis is described, based on finding, for each of the landmark points, the ancestral positions that minimize the distance between the ancestor/descendant points along the tree.
