Spermatophyta Molecular Clock: Time Drift and Recent Acceleration. [PDF]
Plant Environ InteractExponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

Comparative Analysis of Diversification Rates in Clonal and Non-Clonal Flowering Plants. [PDF]
Ecol LettUsing data from 16,465 angiosperm species across 2,997 genera, we classified genera as clonal, mixed, or non‐clonal and estimated diversification using genus‐level phylogeny with DR, MoM, and BAMM. Clonal genera consistently showed lower diversification rates than mixed and non‐clonal genera across all methods.

Herbivory Dominates the Spring Diet of American Black Bears (<i>Ursus americanus</i>) in a Wood Bison (<i>Bison bison athabascae</i>) Neonatal Range, Suggesting Minimal Bison Consumption. [PDF]
Ecol EvolIn this study, we used scat analysis and DNA metabarcoding to analyze the spring diet of black bears in the neonatal range of a small, threatened wood bison herd in northeast Alberta to assess predation risk of neonate bison. Our results suggest that consumption rates of bison are low and that predation risk to neonate wood bison, during the RLBH's ...
