Mountain regions are unusually biodiverse, with rich aggregations of small-ranged species
that form centers of endemism. Mountains play an array of roles for Earth's biodiversity and …

The Amazon hosts one of the largest and richest rainforests in the world, but its origins
remain debated. Growing evidence suggests that geodiversity and geological history played …

Large-scale, time-calibrated phylogenies from supermatrix studies have become crucial for
evolutionary and ecological studies in many groups of organisms. However, in frogs (anuran …

Identifying and protecting hotspots of endemism and species richness is crucial for
mitigating the global biodiversity crisis. However, our understanding of spatial diversity …

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 …

Glassfrogs (family: Centrolenidae) represent a fantastic radiation (~ 150 described species)
of Neotropical anurans that originated in South America and dispersed into Central America …

Understanding the factors that cause heterogeneity among gene trees can increase the
accuracy of species trees. Discordant signals across the genome are commonly produced …

Estimating time-dependent rates of speciation and extinction from dated phylogenetic trees
of extant species (timetrees), and determining how and why they vary, is key to …

Estimates of diversification rates are invaluable for many macroevolutionary studies.
Recently, an approach called BAMM (Bayesian Analysis of Macro-evolutionary Mixtures) …
