Diversity Dynamics in Nymphalidae Butterflies: Effect of Phylogenetic Uncertainty on Diversification Rate Shift Estimates
The species rich butterfly family Nymphalidae has been used to study evolutionary interactions between plants and insects. Theories of insect-hostplant dynamics predict accelerated diversification due to key innovations. In evolutionary biology, analysis of maximum credibility trees in the software MEDUSA (modelling evolutionary diversity using stepwise AIC) is a popular method for estimation o...
متن کاملA parametric method for assessing diversification-rate variation in phylogenetic trees.
Phylogenetic hypotheses are frequently used to examine variation in rates of diversification across the history of a group. Patterns of diversification-rate variation can be used to infer underlying ecological and evolutionary processes responsible for patterns of cladogenesis. Most existing methods examine rate variation through time. Methods for examining differences in diversification among ...
متن کاملGlobal variation in the diversification rate of passerine birds.
Net diversification rates were estimated for samples of primarily tribe-to-family-level clades of passerine birds, taking into account extinction as well as speciation. Two samples were used. The first consisted of 37 clades of primarily temperate North American and primarily tropical South American passerines; the second comprised a global set of 90 clades, each distributed within one or more ...
متن کاملAmong-site rate variation and its impact on phylogenetic analyses.
Although several decades of study have revealed the ubiquity of variation of evolutionary rates among sites, reliable methods for studying rate variation were not developed until very recently. Early methods fit theoretical distributions to the numbers of changes at sites inferred by parsimony and substantially underestimate the rate variation. Recent analyses show that failure to account for r...
متن کاملProlonged decay of molecular rate estimates for metazoan mitochondrial DNA
Evolutionary timescales can be estimated from genetic data using the molecular clock, often calibrated by fossil or geological evidence. However, estimates of molecular rates in mitochondrial DNA appear to scale negatively with the age of the clock calibration. Although such a pattern has been observed in a limited range of data sets, it has not been studied on a large scale in metazoans. In ad...
