Allometry refers to the size-related changes of morphological traits and remains an essential
concept for the study of evolution and development. This review is the first systematic …

Genital morphology is informative phylogenetically and strongly selected sexually. We use a
recent species-level phylogeny of nephilid spiders to synthesize phylogenetic patterns in …

Phenotypic plasticity is a developmental process that plays a role as a source of variation for
evolution. Models of adaptive divergence make the prediction that increasing ecological …

Despite only comprising seven species, extant sea turtles (Cheloniidae and
Dermochelyidae) display great ecological diversity, with most species inhabiting a unique …

To understand the effect of metal pollution on the speciation process, we conducted
comparative analyses of six populations of the gastropod Melanoides tuberculata, which …

Morphological diversification does not proceed evenly across the organism. Some body
parts tend to evolve at higher rates than others, and these rate biases are often attributed to …

After near extirpation by nineteenth century whaling, New Zealand's southern right whales
(Eubalaena australis) are recovering strongly, calving almost exclusively at the subantarctic …

The dusky grouper (Epinephelus marginatus) is a vulnerable predatory fish found in the
Atlantic and Indian oceans, and in the Mediterranean Sea. This study investigates the …

Intrapopulation diet specializations may result from the use of different dietary items or
foraging tactics by individuals within a single population. The damselfish, Dascyllus …

Background Quantitative studies of the variation of disparity during ontogeny exhibited by
the radiation of coral reef fishes are lacking. Such studies dealing with the variation of …
