Examining biological diversity in an explicitly evolutionary context has been the subject of
research for several decades, yet relatively recent advances in analytical techniques and the …

Aim Whether intraspecific spatial patterns in body size are generalizable across species
remains contentious, as well as the mechanisms underlying these patterns. Here we test …

Increasing body and brain size constitutes a key macro-evolutionary pattern in the hominin
lineage, yet the mechanisms behind these changes remain debated. Hypothesized drivers …

Although Bergmann's rule–stating that among closely related species, the bigger ones will
inhabit the colder climates/higher latitudes–was formulated for inter‐specific comparisons …

Background Bergmann's rule proposes that animals in cold habitats will be larger than those
in warm habitats. This prediction has been tested thoroughly at the intraspecific level, but …

Understanding why some species are more susceptible to extinction than others is critical for
implementing effective conservation strategies. Phylogenetic comparative methods (PCMs) …

Although variation in the color of light in terrestrial diurnal and twilight environments has
been well documented, relatively little work has examined the color of light in nocturnal …

Environmental stress on primate populations can take many forms. Abiotic factors, such as
temperature and precipitation, may directly influence the behavior of primates owing to …

Several factors can influence primate distributions, including evolutionary history,
interspecific competition, climate, and anthropogenic impacts. In Madagascar, several small …

Mammals display considerable geographical variation in life history traits. To understand
how climatic factors might influence this variation, we analysed the relationship between life …
