Limitations of Climatic Data for Inferring Species Boundaries: Insights from Speckled Rattlesnakes
Phenotypes, DNA, and measures of ecological differences are widely used in species delimitation. Although rarely defined in such studies, ecological divergence is almost always approximated using multivariate climatic data associated with sets of specimens (i.e., the "climatic niche"); the justification for this approach is that species-specific climatic envelopes act as surrogates for physiolo...
متن کاملInferring species-level phylogenies and taxonomic distinctiveness using multilocus data in Sistrurus rattlesnakes.
Phylogenetic relationships and taxonomic distinctiveness of closely related species and subspecies are most accurately inferred from data derived from multiple independent loci. Here, we apply several approaches for understanding species-level relationships using data from 18 nuclear DNA loci and 1 mitochondrial DNA locus within currently described species and subspecies of Sistrurus rattlesnak...
متن کاملBody Size Evolution in Insular Speckled Rattlesnakes (Viperidae: Crotalus mitchellii)
BACKGROUND Speckled rattlesnakes (Crotalus mitchellii) inhabit multiple islands off the coast of Baja California, Mexico. Two of the 14 known insular populations have been recognized as subspecies based primarily on body size divergence from putative mainland ancestral populations; however, a survey of body size variation from other islands occupied by these snakes has not been previously repor...
متن کاملInferring Ecological Networks From Species Abundance Data
Network reconstruction methods are commonly used in molecular biology to construct regulatory networks from information about the expression values of genes in a cell. In ecology, we are presented with a similar problem when trying to reconstruct species interaction networks based on species abundance data. The aim of this project was to see if the methods that proved successful in molecular bi...
متن کاملInferring species interactions from co-occurrence data with Markov networks.
Inferring species interactions from co-occurrence data is one of the most controversial tasks in community ecology. One difficulty is that a single pairwise interaction can ripple through an ecological network and produce surprising indirect consequences. For example, the negative correlation between two competing species can be reversed in the presence of a third species that outcompetes both ...
