One of the most important shifts in evolutionary biology in the past 50 years is an increased
recognition of sluggish evolution and failures to adapt, which seem paradoxical in view of …

Bryophytes include about 20,000 species characterized by their poikilohydric condition, high
long-distance dispersal capacities, and cold tolerance. Despite these specific life-history …

A number of methods have been developed to infer differential rates of species
diversification through time and among clades using time-calibrated phylogenetic trees …

The R package 'diversitree'contains a number of classical and contemporary comparative
phylogenetic methods. Key included methods are BiSSE (binary state speciation and …

Geographic characters—traits describing the spatial distribution of a species—may both
affect and be affected by processes associated with lineage birth and death. This is …

Replicate radiations provide powerful comparative systems to address questions about the
interplay between opportunity and innovation in driving episodes of diversification and the …

Comparative biologists often attempt to draw inferences about tempo and mode in evolution
by comparing the fit of evolutionary models to phylogenetic comparative data consisting of a …

Evolution is happening all around us. In many cases–lately, due to technological advances
in molecular biology–scientists can now describe the evolutionary process in exquisite …

Phylogenetic comparative methods are extremely commonly used in evolutionary biology. In
this paper, I highlight some of the problems that are frequently encountered in comparative …

Recent innovations in phylogenetic comparative methods (PCMs) have spurred a
renaissance of research into the causes and consequences of large‐scale patterns of …
