Ecological radiation with limited morphological diversification in salamanders.
A major goal of evolutionary biology is to explain morphological diversity among species. Many studies suggest that much morphological variation is explained by adaptation to different microhabitats. Here, we test whether morphology and microhabitat use are related in plethodontid salamanders, which contain the majority of salamander species, and have radiated into a striking diversity of micro...
متن کاملAccelerated rates of climatic-niche evolution underlie rapid species diversification.
A major goal of ecology is to explain differences in species richness between regions and among clades. The diversification rate of clades is a key parameter for understanding both patterns. Here, we combine phylogenetic and climatic data for 250 species of plethodontid salamanders and show for the first time that rapid species diversification is associated with accelerated climatic-niche evolu...
متن کاملPhylogenetic analysis of ecomorphological divergence, community structure, and diversification rates in dusky salamanders (Plethodontidae: Desmognathus).
An important dimension of adaptive radiation is the degree to which diversification rates fluctuate or remain constant through time. Focusing on plethodontid salamanders of the genus Desmognathus, we present a novel synthetic analysis of phylogeographic history, rates of ecomorphological evolution and species accumulation, and community assembly in an adaptive radiation. Dusky salamanders are h...
متن کاملThe Evolution of Courtship Behavior in Plethodontid Salamanders, Contrasting Patterns of Stasis and Diversification
An examination of courtship in salamanders helps resolve the puzzling problem of long-term evolutionary stasis in behavior. To address the companion issues of stasis and diversification, we summarize and synthesize courtship observations in Rhyacotriton and 13 genera of plethodontids. We use a modular analysis of courtship to identify conservative, as well as variable behavioral elements and se...
متن کاملRapid diversification and dispersal during periods of global warming by plethodontid salamanders.
A phylogeny and timescale derived from analyses of multilocus nuclear DNA sequences for Holarctic genera of plethodontid salamanders reveal them to be an old radiation whose common ancestor diverged from sister taxa in the late Jurassic and underwent rapid diversification during the late Cretaceous. A North American origin of plethodontids was followed by a continental-wide diversification, not...
