septicemic listeriosis in wild hares from saskatchewan, canada.the bacterium listeria monocytogenes causes disease in a wide variety of mammals including rabbits and hares. we describe naturally acquired metritis and septicemic listeriosis in wild female hares from saskatchewan, canada. between april 2012 and july 2013, two white-tailed jackrabbits (lepus townsendii) and a snowshoe hare (lepus americanus) were presented to the veterinary medical centre at the western college of veterinary medicine, saskatoon, saskatchewan, canada with nonspecific neurologic ...201525647601
malignant mesenchymal tumors in two white-tailed jack rabbits (lepus townsendii).two white-tailed jack rabbits (lepus townsendii) with proliferative lesions in their internal organs were submitted to the canadian cooperative wildlife health centre (saskatoon, saskatchewan, canada) for necropsy because of concern that dogs that had contact with the hares might have been exposed to an infectious disease. in both hares, the primary diagnosis was neoplasia. one hare had metastatic leiomyosarcoma and uterine fibroma, the other had metastatic mesenchymal tumors involving the liver ...200415650095
hares on ice: phylogeography and historical demographics of lepus arcticus, l. othus, and l. timidus (mammalia: lagomorpha).phylogeographical investigations of arctic organisms provide spatial and temporal frameworks for interpreting the role of climate change on biotic diversity in high-latitude ecosystems. phylogenetic analyses were conducted on 473 base pairs of the mitochondrial control region in 192 arctic hares (lepus arcticus, lepus othus, lepus timidus) and two individual lepus townsendii. the three arctic hare species are closely related. all l. othus individuals form one well-supported clade, l. arcticus in ...200516101770
the hidden history of the snowshoe hare, lepus americanus: extensive mitochondrial dna introgression inferred from multilocus genetic variation.hybridization drives the evolutionary trajectory of many species or local populations, and assessing the geographic extent and genetic impact of interspecific gene flow may provide invaluable clues to understand population divergence or the adaptive relevance of admixture. in north america, hares (lepus spp.) are key species for ecosystem dynamics and their evolutionary history may have been affected by hybridization. here we reconstructed the speciation history of the three most widespread hare ...201425113393
