Evolutionary biology is multivariate, and advances in phylogenetic comparative methods for
multivariate phenotypes have surged to accommodate this fact. Evolutionary trends in …

The characiform fishes of the Neotropics and Africa radiated remarkably in ecomorphology,
but the macroevolutionary processes responsible for their biodiversity remain unexplored …

Abstract The IUCN Red List (RL) provides high-quality conservation assessments for
individual species, yet the rate and scale of environmental deterioration globally challenges …

Background Darwin and others proposed that a species' geographic range size positively
influences speciation likelihood, with the relationship potentially dependent on the mode of …

Understanding the phylogeographic history of a group and identifying the factors
contributing to speciation is an important challenge in evolutionary biology. The Goodeinae …

Vitellogenin (Vtg), a yolk nutrient protein that is synthesized in the livers of female animals,
and subsequently carried into the ovary, contributes to vitellogenesis in oviparous animals …

Parasitism is often invoked as a factor explaining the variation in diversification rates across
the tree of life, while also representing up to half of Earth's diversity. Yet, patterns and …

Nitrate-nitrogen (NO3-N) pollution related to anthropogenic activities is increasing in
freshwater ecosystems. Knowledge about NO3-N sensitivity in freshwater wild fish is needed …

We analysed phylogenetic relationships within a major clade of Cyprinodontiformes
(Teleostei) that includes five families of North American killifishes. We used DNA sequences …

The mechanism via which the mothers of viviparous animals regulate the internal
environment of pregnancy-associated organs for maintaining offspring growth is poorly …
