Data from: Body size evolution in otters distinguished from terrestrial mustelids
<p>Some taxa of mammals live in water, all of which evolved from land-dwelling ancestors. In the family Mustelidae (Mammalia: Carnivora), most species live on land, while otters, comprising the subfamily Lutrinae, inhabit aquatic environments, which include the almost exclusively aquatic sea otters (<em>Enhydra lutris</em>). Thus, the transition from a terrestrial to an aquatic lifestyle has occurred within this family. Despite potentially different selection pressures on body size in aquatic and terrestrial habitats, no divergence in the evolutionary pattern of body size between otters and other mustelids has previously been shown using models of trait evolution on a phylogeny. We applied models that explicitly incorporated lineage-specific directional selection to the evolution of body mass in living mustelids. Using a simulation-based likelihood and approximate Bayesian computation approach, we demonstrated lineage-specific directional selection for larger body mass in otters, which is distinct from other mustelids. There was no evidence of a difference between sea otters and other otters in the strength of directional selection for larger body mass. Additionally, our analyses supported no difference in the rate at which body mass evolves in both directions between otters and other mustelids. These findings suggest that the evolution of body mass in otters is associated with selective advantages of larger size rather than the relaxation of constraints on body size in aquatic habitats, like other aquatic mammals such as sirenians, cetaceans, and pinnipeds.</p>
Data from: The little fishes that could: smaller fishes demonstrate slow body size evolution but faster speciation in the family Percidae
<p>Body size impacts numerous aspects of organismal biology and many factors have been invoked to explain body size distributions in a macroecological and macroevolutionary context. Body size in the freshwater fish family Percidae is strongly right-skewed (i.e, dominated by small sizes), with small body size potentially being associated with fast water habitats. We constructed a new species-level, multi-locus, time-calibrated phylogeny of Percidae, and used it to test for changes in the rate and pattern of maximum body size evolution. We also tested whether speciation rates varied as a function of body size. We found that Etheostomatinae evolved towards a smaller adaptive optimum in body size compared to the other subfamilies of Percidae, and that this shift was associated with a reduction in the rate of body size evolution. Speciation rates were associated with body size across percids, showing a peak around small to medium body size. Small body size appears to partially, but not fully, explain the diversity of small percids, as many darters fall well below the "optimum" body size. Reinforcement of selection for small body size via selection for novel morphologies or via sexual selection may help to fully explain the remarkable diversity of the darter radiation.</p>
