There is increasing evidence that phenotypic plasticity can promote population divergence
by facilitating phenotypic diversification and, eventually, genetic divergence. When a …

Cichlid fishes are hypothesized to encompass several independent adaptive radiations that
display increased diversification rates and impressive ecological heterogeneity. Here, I …

Most contemporary studies of adaptive radiation focus on relatively recent and
geographically restricted clades. It is less clear whether diversification of ancient clades …

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

Trade-offs are thought to bias evolution and are core features of many anatomical systems.
Therefore, trade-offs may have far-reaching macroevolutionary consequences, including …

Studies of cichlid evolution have highlighted the importance of visual pigment genes in the
spectacular radiation of the African rift lake cichlids. Recent work, however, has also …

Ecomorphology is the study of relationships between organismal morphology and ecology.
As such, it is the only way to determine if morphometric data can be used as an informative …

Innovations can facilitate bursts of diversification by increasing access to novel resources
and the attainment of novel functional designs. Pharyngognathy, exhibited by highly diverse …

Adaptive radiations have been hypothesized to contribute broadly to the diversity of
organisms. Models of adaptive radiation predict that ecological opportunity and ecological …

Despite divergent evolutionary histories, Neotropical cichlids (Cichlidae) and Nearctic
sunfishes (Centrarchidae) appear to have similar functional morphotypes and occupy similar …
