Microhabitat and Climatic Niche Change Explain Patterns of Diversification among Frog Families.
A major goal of ecology and evolutionary biology is to explain patterns of species richness among clades. Differences in rates of net diversification (speciation minus extinction over time) may often explain these patterns, but the factors that drive variation in diversification rates remain uncertain. Three important candidates are climatic niche position (e.g., whether clades are primarily te...
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 کاملIs diversification rate related to climatic niche width?
Methods We characterized climatic niches for 5784 amphibian species using databases for species distributions and climate. We estimated the niche width of each family using the range of values for climatic variables across all sampled species, and using the mean of species niche widths. We estimated diversification rates for families given their total number of described species and a timecalib...
متن کاملRates of projected climate change dramatically exceed past rates of climatic niche evolution among vertebrate species.
A key question in predicting responses to anthropogenic climate change is: how quickly can species adapt to different climatic conditions? Here, we take a phylogenetic approach to this question. We use 17 time-calibrated phylogenies representing the major tetrapod clades (amphibians, birds, crocodilians, mammals, squamates, turtles) and climatic data from distributions of > 500 extant species. ...
متن کاملFaster diversification on land than sea helps explain global biodiversity patterns among habitats and animal phyla.
Terrestrial environments occupy ~ 30% of the Earth's surface yet contain ~ 80% of all species. The causes of this dramatic biodiversity gradient have remained relatively unstudied. Here, I test the fundamental prediction that predominantly non-marine clades have more rapid rates of diversification than marine clades, using a time-calibrated phylogeny of animal phyla. The results strongly suppor...
