Data from: Rapid phenotypic change in a native bird population following conversion of the Colorado Desert to agriculture

Nicholas A. Mason & Philip Unitt
Humans are modifying our planet’s ecosystems with increasing frequency and intensity. Exploring population responses to anthropogenic modifications of natural habitat provides insights into how species persist in the Anthropocene. Here, we leverage natural history collections to document rapid phenotypic change within a native bird population following 80 years of agriculture in the Colorado Desert of southeastern California. By comparing spectrophotometric measurements of Horned Lark (Eremophila alpestris) specimens collected in the Imperial Valley from 1918 to...

Data from: Pleistocene climatic fluctuations drive isolation and secondary contact in the red diamond rattlesnake (Crotalus ruber) in Baja California

Sean M. Harrington, Bradford D. Hollingsworth, Timothy E. Higham & Tod W. Reeder
Aim: Many studies have investigated the phylogeographic history of species on the Baja California Peninsula, and they often show one or more genetic breaks that are spatially concordant among many taxa. These phylogeographic breaks are commonly attributed to vicariance as a result of geological or climatic changes, followed by secondary contact when barriers are no longer present. We use restriction-site associated DNA sequence data and a phylogeographic model selection approach to explicitly test the secondary...
