Richardson's Ground Squirrel occurrence in Saskatchewan
<p>Richardson's ground squirrel (<i>Urocitellus richardsonii,</i> Sabine 1822) is a widespread burrowing mammal on the Northern Great Plains. This species is a key prey item for a variety of predators, and its burrows provide important habitat for other wildlife; however, Richardson's ground squirrel is also considered an economically damaging agricultural pest. Despite the ecological importance of Richardson's ground squirrels and their status as pests, there are gaps in our knowledge about large-scale habitat associations for this species. In 2011 and 2012, we conducted 1840 road-side surveys in a 130,000-km<sup>2 </sup>area of southern Saskatchewan, Canada to understand which habitat features are associated with Richardson's Ground Squirrel occurrence. Ground squirrels were observed during only 8% of the surveys. Probability of ground squirrel occurrence was highest in areas with moderate amounts of grassland (approximately 30%), areas that were developed by humans (>30%), and had a high proportion of clay loam soils, presumably for burrowing. Our study highlights the importance of heterogeneous landscapes and that areas disturbed by humans may provide suitable vegetation structure for ground squirrels. This information can help to identify important habitat for species that rely on Richardson's ground squirrels and identify areas where they could come into conflict with agriculture.</p>

Fig. 1.—Map of the Freeman Gulch study area in the west-central portion of the geographic range of the Mohave ground squirrel (MGS) in the Mojave Desert, California. The study area is approximately indicated by a minimum convex polygon drawn around all MGS radiotelemetry locations collected in 2003–2004. The Coso Range, in which MGS studies were conducted in the 1990s, is located in the northern portion of the MGS range. The top inset map shows juvenile and adult MGS locations within the Freeman Gulch study area. The cluster of locations in the extreme northeast of the inset was from a single individual that made a long-distance movement as a juvenile in 2003 and established a home range as an adult the following year. The bottom inset map shows the location of the MGS range in southern California.

Data from: Ectoparasites and fitness of female Columbian ground squirrels
Parasites play an important role in the evolution of host traits via natural selection, coevolution and sexually selected ornaments used in mate choice. These evolutionary scenarios assume fitness costs for hosts. To test this assumption, we conducted an ectoparasite removal experiment in free-living Columbian ground squirrels (Urocittelus columbianus) in four populations over three years. Adult females were randomly chosen to be either experimentally treated with anti-parasite treatments (spot-on solution and flea powder, N = 61) or a sham treatment (control, N = 44). We expected that experimental females would show better body condition, increased reproductive success and enhanced survival. Contrary to our expectations, body mass was not significantly different between treatments at mating, birth of litter or weaning of young. Further, neither number nor size of young at weaning differed significantly between the two treatments. Survival to the next spring for adult females and juveniles was not significantly different between experimental and control treatments. Finally, annual fitness was not affected by the treatments. We concluded that females and their offspring were able compensate for the presence of ectoparasites, suggesting little or no fitness costs of parasites for females in the different colonies and during the years of our experiments.
Genetic characterization of potential venom resistance proteins in California ground squirrels (Otospermophilus beecheyi) using transcriptome analyses
<p>Understanding the molecular basis of adaptations in coevolving species requires identifying the genes that underlie reciprocally selected phenotypes, such as those involved in venom in snakes and resistance to venom in their prey. In this regard, California ground squirrels (CGS; Otospermophilus beecheyi) are eaten by northern Pacific rattlesnakes (Crotalus oreganus oreganus), but individual squirrels may still show substantial resistance to venom and survive bites. A recent study using proteomics identified venom interactive proteins (VIPs) in the blood serum of CGS. These VIPs represent possible resistance proteins, but the sequences of genes encoding them are unknown despite the value of such data to molecular studies of coevolution. To address this issue, we analyzed a de novo assembled transcriptome from CGS liver tissue—where many plasma proteins are synthesized—and other tissues from this species. We then examined VIP sequences in terms of three characteristics that identify them as possible resistance proteins: evidence for positive selection, high liver expression, and nonsynonymous variation across CGS populations. Based on these characteristics, we identified five VIPs (i.e., alpha-2-macroglobulin, alpha-1-antitrypsin-like protein GS55-LT, apolipoprotein A-II, hibernation-associated plasma protein HP-20, and hibernation-associated plasma protein HP-27) as the most likely candidates for resistance proteins among VIPs identified to date. Four of these proteins have been previously implicated in conferring resistance to venom in mammals, validating our approach. When combined with the detailed information available for rattlesnake venom proteins, these results set the stage for future work focused on understanding coevolutionary interactions at the molecular level between these species.</p>
