Data for an unusually dense population of Sphodros rufipes (Latreille 1829) (Mygalomorphae, Atypidae) at the edge of its range on Tuckernuck Island, Massachusetts
<p>Data submitted in fulfillment of a 2008 Nantucket Biodiversity Initiative grant.</p> <p>Paper Abstract: We counted and measured <em>Sphodros rufipes</em> (Latreille 1829) pursewebs in two survey plots on Tuckernuck Island, Massachusetts. Tuckernuck is 50 Km south of Cape Cod, Massachusetts, and is entirely owned by private landowners or conservation organizations; biological research activities are supported and encouraged by residents on a limited basis. Our objectives were to quantify web density and determine the main components of the <em>S. rufipes</em> diet. We counted 479 webs in the two plots and report web densities between 0.058 and 0.18 webs/m<sup>2</sup>; denser than previously reported populations. Contrary to most previously published literature on <em>S. rufipes,</em> we noted the predominance of the grass-like sedge, <em>Carex pensylvanica,</em> rather than trees, as a web support. However, we also offer the first report of <em>S. rufipes </em>using a conifer (<em>Pinus rigida</em>) as a web support. Coleopterans and isopods made up 79 percent of the prey parts collected from 56 pursewebs. We suggest that the Tuckernuck population offers an opportunity to collect important long-term demographic data.</p> <p>Datasets:<br> sphodrosWebLocations.csv - data from two specific areas<br> sphodrosSpiderMeasurements.csv - measurements of live spiders borrowed from their webs<br> sphodrosRandomWebLocations.csv - data for webs found by happenstance<br> sphodrosDiet.csv - diet data from body parts collected from Sphodros webs<br> sphodrosDataDictionary.csv</p>

Data from: Genetic and environmental canalization are not correlated among altitudinally varying populations of Drosophila melanogaster
<p>Organisms are exposed to environmental and mutational effects influencing both mean and variance of phenotypes. Potentially deleterious effects arising from this variation can be reduced by the evolution of buffering (canalizing) mechanisms, ultimately reducing phenotypic variability. There has been interest regarding the conditions enabling the evolution of canalization. Under some models, the circumstances under which genetic canalization evolves is limited, despite apparent empirical evidence for it. It has been argued that genetic canalization evolves as a correlated response to environmental canalization (congruence model). Yet, empirical evidence has not consistently supported predictions of a correlation between genetic and environmental canalization. In a recent study, a population of <em>Drosophila </em>adapted to high altitude showed evidence of genetic decanalization relative to those from low altitudes. Using strains derived from these populations, we tested if they varied for multiple aspects of environmental canalization We observed the expected differences in wing size, shape, cell (trichome) density and mutational defects between high- and low-altitude populations. However, we observed little evidence for a relationship between measures of environmental canalization with population or with defect frequency. Our results do not support the predicted association between genetic and environmental canalization.</p>
Geographic patterns in morphometric and genetic variation for coyote populations with emphasis on southeastern coyotes
Prior to 1900, coyotes (Canis latrans) were restricted to the western and central regions of North America, but by the early 2000s coyotes became ubiquitous throughout the eastern United States. Information regarding morphological and genetic structure of coyote populations in the southeastern United States is limited, and where data exist, they are rarely compared to those from other regions of North America. We assessed geographic patterns in morphology and genetics of coyotes with special consideration of coyotes in the southeastern United States. Mean body mass of coyote populations increased along a west-to-east gradient, with southeastern coyotes being intermediate to western and northeastern coyotes. Similarly, principal component analysis of body mass and linear body measurements suggested that southeastern coyotes were intermediate to western and northeastern coyotes in body size but exhibited shorter tails and ears from other populations. Genetic analyses indicated that southeastern coyotes represented a distinct genetic cluster that differentiated strongly from western and northeastern coyotes. We postulate that southeastern coyotes experienced lower immigration from western populations than did northeastern coyotes, and over time, genetically diverged from both western and northeastern populations. Coyotes colonizing eastern North America experienced different selective pressures than did stable populations in the core range and we offer that the larger body size of eastern coyotes reflect an adaptation that improved dispersal capabilities of individuals in the expanding range.
