Data from: Evolutionary dynamics of a rapidly receding southern range boundary in the threatened California Red-Legged Frog (Rana draytonii)
Populations forming the edge of a species range are often imperiled by isolation and low genetic diversity, with proximity to human population centers being a major determinant of edge stability in modern landscapes. Since the 1960s, the California red-legged frog (Rana draytonii) has undergone extensive declines in heavily urbanized southern California, where the range edge has rapidly contracted northward while shifting its cardinal orientation to an east-west trending axis. We studied the genetic structure and diversity of these frontline populations, tested for signatures of contemporary disturbance, specifically fire, and attempted to disentangle these signals from demographic events extending deeper into the past. Consistent with the genetic expectations of the 'abundant-center' model, we found that diversity, admixture, and opportunity for random mating increases in populations sampled successively further away from the range boundary. Demographic simulations indicate that bottlenecks in peripheral isolates are associated with processes extending tens to a few hundred generations in the past, despite the demographic collapse of some due to recent fire-flood events. While the effects of recent disturbance have left little genetic imprint on these populations, they likely contribute to an extinction debt that will lead to continued range contraction unless management intervenes to stall or reverse the process.
Distribution. Historically ranged through the Atlantic Forest in the states of Bahia, Espirito Santo, Minas Gerais, and Rio de Janeiro, excluding only lowland forests in the extreme S of Bahia and N Espirito Santo, the N limit of the distribution was probably the Rio Jequirica or the right bank of the Rio Paraguacu, and the S limit is still poorly defined but is probably the Serra da Mantiqueira in S Minas Gerais, near the state boundaries with Rio de Janeiro and Sao Paulo where it meets the distribution of the Southern Muriqui (B. arachnoides). in Atelidae

Data from: Spatial variation in bioclimatic relationships for a snow-adapted species along a discontinuous southern range boundary
<p>Documenting variation in the relationship between climate variables and species occurence at range boundaries can help reveal how species will respond to global climate change. We collected snowshoe hare (Lepus americanus) presence-absence data from snow-track surveys conducted in the U.S. states of Michigan and Wisconsin in winters from 2012-2014 at their southern range boundary in the region. A series of 125m transects were walked at each site within a week of fresh snowfall, and the presence or absence of snowshoe hare tracks on each transect was recorded. Data set also includes the variables mean 5-year snow cover duration, mean 5-year maximum temperature, and percentage forest cover at each site. Each variable was used in data analysis for the related paper to relate snowshoe hare occurrence to climate and land cover variables at the southern edge of their distribution. Snowshoe hares in the region occur in areas with longer snow cover duration and lower maximum temperatures but these relationships vary across the study area such that maximum temperature was positively correlated with snowshoe hare occurrence in the northern portion of the study area (Upper Peninsula of Michigan).</p>
