Ecological and evolutionary consequences of biotic homogenization.
The goal is to initiate future research that investigates the broader conservation implications of homogenization and to promote a proactive style of adaptive management that engages the human component of the anthropogenic blender that is currently mixing the biota on Earth. Expand
Evolution of rattlesnakes (Viperidae; Crotalus) in the warm deserts of western North America shaped by Neogene vicariance and Quaternary climate change
During Pleistocene, the Laurentide ice sheet rearranged and diversified biotic distributions in eastern North America, yet had minimal physical impact in western North America where lineageExpand
Does morphology predict ecology? Hypothesis testing within a freshwater stream fish assemblage
Ecomorphological analyses appear to be a valid assay for structure within fish assemblages only when limited to within-family comparisons (where the effects of history appear less significant) when many different families are involved in the analysis. Expand
Statistical comparison of proximity matrices: applications in animal behaviour
A general method of matrix comparison, called the Mantel test, is described which accounts for interdependencies in association values derived for all pairs of individuals and has wide applicability in studies of animal behaviour. Expand
Origin of Gila seminuda (Teleostei: Cyprinidae) through introgressive hybridization: implications for evolution and conservation.
Results support an origin of the bisexual taxon G. seminuda through introgressive hybridization in fishes from the Virgin River, Arizona-Nevada-Utah. Expand
Small Fish in a Large Landscape: Diversification of Rhinichthys osculus (Cyprinidae) in Western North America
The map of 112 restriction sites in the mitochondrial DNA genome of the Speckled Dace suggested at least three separate ichthyofaunal invasions of California, as well as a Bonneville Basin fragmented by a north-south connection between southeastern Idaho and the Colorado River. Expand
Quantitative Matrix Comparisons in Ecological and Evolutionary Investigations
It is found that differences in color polymorphisms covary significantly with differences in predator densities and in altitudes, suggesting that malecolor polymorphisms track clinally distributed communities of visually hunting predators. Expand
Conservation phylogenetics of helodermatid lizards using multiple molecular markers and a supertree approach.
The conservation phylogenetic approach emphasizes the origin and diversification of this group, yields information on the manner by which past environmental variance may have impacted its populations and, in turn, allows us to disentangle historic from contemporary impacts that might threaten its long-term persistence.
