The dataset contains the recorded locations of amphibians collected in Southeast Alaska from 1867 to 2002. The records were compiled from 15 university and museum collections in the US and Canada. The data contain records for the following species: Northwestern Salamander, Long-toed Salamander, Roughskin Newt, Western Toad, Pacific Chorus Frog, Columbia Spotted Frog, Wood Frog, and the Red-legged Frog.
Landscape features such as mountains, rivers, and ecological gradients may strongly affect patterns of dispersal and gene flow among populations and thereby shape population dynamics and evolutionary trajectories. The landscape may have a particularly strong effect on patterns of dispersal and gene flow in amphibians because amphibians are thought to have poor dispersal abilities. We examined genetic variation at six microsatellite loci in Columbia spotted frogs (Rana luteiventris) from 28 breeding ponds in western Montana and Idaho, USA, in order to investigate the effects of landscape structure on patterns of gene flow. We were particularly interested in addressing three questions: (i) do ridges act as barriers...

We investigated population dynamics in boreal toads relative to abiotic (fall temperatures and snowpack -the covariates provided here) and biotic (the abundance of another anuran host,data provide here) characteristics of the local environment at 6 sites in Wyoming, USA. We used capture-recapture data (i.e., 1 or 0, provided here) and a robust design multi-state model framework that incorporates disease state uncertainty to assess our a priori hypotheses about interactions among covariates (temperature, snowpack and presence of spotted frogs) and boreal toad survival. Files include: br_bd.csv, disease data; br_cmr.csv, capture-mark recapture data (1,0); br_cov.csv, soil and snow information detailed in this file;...
