Our lab's PhD student Daniel take on body size biases in tetrapod taxonomy:
nsojournals.onlinelibrary.wiley.com
While species descriptions are rooted in biological diversity, their timing and patterns have also been influenced by historical, socioeconomic, and perceptual biases. Among these, body size has...

Our big squamate origins and early evolution review is now fully published as open access! with M. Tollis and F. Burbrink https://t.co/ljR8vp4G5H
annualreviews.org
Squamates (lizards, including snakes) are the most diverse group of terrestrial vertebrates on Earth today and have an evolutionary history dating back to at least the Middle Triassic (ca. 242 Mya)....

New paper! Lead by Julia de Souza, and in collaboration with our dear colleagues, we have looked back to the anatomy of a long forgotten Dinodontosaurus skull. Result: considering the current diagnosis, we now have D. brevirostris in Brazil! + https://t.co/I3f5lS8c7L

Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod...

We suggest this is inherent to the very distinct nature of these datatypes and the way they are collected, and we provide a conceptual framework from what can be concluded by evolutionary rates studies using each datatype.

Lack of comparability across existing methods makes definite conclusions more limited than what we wanted, but the biggest difference in our comparisons is always across datatypes.

We included discrete (phylogenetic characters) and continuous data (from 2D GMM) from the exact same species and, in most cases, from the exact same specimens. That was a lot of work…

We try to assess whether rates of phenotypic evolution based on multivariate data (discrete and continuous), using popular methods, and which influence how we measure phenotypic change and innovation across lineages provide comparable results. The answer is a very big NO.

Our latest paper, now on how to conciliate apparently discrepant evolutionary rate patterns in squamates, but which may well apply to any study system with @MCZpaleo and former student Arthur Brum #macroevolution

Abstract. Understanding the rate of phenotypic evolution can reveal fundamental aspects of organismal evolutionary trajectories. Hence, several studies hav

New stuff: combine_log now also combines posterior log files from BEAST2 and MCMCTREE; write_partitioned_alignments2 writes partitioned data as separate alignments for any data type; clade_membership designates clade membership for each tip for in the tree used by other functions
