Ecological character displacement, mostly seen as increased differences of size in sympatry
between closely‐related or similar species, is a focal hypothesis assuming that species too …

Adaptive radiation is a response to natural selection and ecological opportunity involving
diversification of species and associated adaptations. Although evolutionary biologists have …

Biologists employ phylogenetic comparative methods to study adaptive evolution. However,
none of the popular methods model selection directly. We explain and develop a method …

Identification of general properties of evolutionary radiations has been hindered by the lack
of a general statistical and phylogenetic approach applicable across diverse taxa. We …

All reef-forming corals depend on the photosynthesis performed by their algal symbiont, and
such corals are therefore restricted to the photic zone. The intensity of light in this zone …

A common problem in molecular phylogenetics is choosing a model of DNA substitution that
does a good job of explaining the DNA sequence alignment without introducing superfluous …

Large islands typically have more species than comparable smaller islands. Ecological
theories, the most influential being the equilibrium theory of island biogeography, explain …

Anolis lizards (anoles) are textbook study organisms in evolution and ecology. Although
several topics in evolutionary biology have been elucidated by the study of anoles, progress …

It is commonly argued that sexual size dimorphism (SSD) in lizards has evolved in response
to two primary, nonexclusive processes:(1) sexual selection for large male size, which …

By their very nature oceanic island ecosystems offer great opportunities for the study of
evolution and have for a long time been recognized as natural laboratories for studying …
