Tropical Africa is home to an astonishing biodiversity occurring in a variety of ecosystems.
Past climatic change and geological events have impacted the evolution and diversification …

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 …

Understanding the origins of species richness patterns is a fundamental goal in ecology and
evolutionary biology. Much research has focused on explaining two kinds of species …

Rates of species formation vary widely across the tree of life and contribute to massive
disparities in species richness among clades. This variation can emerge from differences in …

A fascinating pattern in nature is the uneven distribution of biodiversity among clades, some
with low species richness and phenotypic variation in contrast to others with remarkable …

Conspicuous colors (eg, red, yellow, blue) have evolved numerous times across animals.
But the function of this coloration can differ radically among species. Many species use this …

Color polymorphism—two or more heritable color phenotypes maintained within a single
breeding population—is an extreme type of intraspecific diversity widespread across the tree …

Abstract Machine learning (ML) newly enables tests for higher inter-species diversity in
visible phenotype (disparity) among males versus females, predictions made from …

Examining the role of color in mate choice without testing what colors the study animal is
capable of seeing can lead to ill-posed hypotheses and erroneous conclusions. Here, we …

Secondary sympatry amongst sister lineages is strongly associated with genetic and
ecological divergence. This pattern suggests that for closely related species to coexist in …
