TL;DR: It is concluded that morphological plasticity is common in at least six families of northern freshwater fishes, plastic responses can often be induced by conditions related to littoral and pelagic lake environments, and plasticity often represents adaptive responses to conditions in these habitats.

TL;DR: It is shown that specific changes in trophic anatomy have evolved repeatedly in the African rift lakes, and the results suggest that simple morphological alterations that have large ecological consequences are likely to constitute critical components of adaptive radiations in functional morphology.

TL;DR: The results indicate that geometric morphometrics can be a more effective way to analyze and interpret body form, but also that traditional methods can be relied upon to provide statistical evidence of shape differences, although not necessarily accurate information about the nature of variation in shape.

TL;DR: It is suggested that early adaptive evolution in a novel environment can include changes to plastic character states and the genetic assimilation of coordinated plastic responses could result in the further, and possibly rapid, divergence of such populations and could also account for the evolution of genes of major effect that contribute to suites of phenotypic differences between divergent populations.

TL;DR: Insight is provided into the genetic basis of complex and continuous patterns of colour variation in cichlid fishes, which offer a vast diversity of pigmentation patterns that have evolved in response to both natural and sexual selection.
