| vector-borne pathogens in arctic foxes, vulpes lagopus, from canada. | because of the relatively low biodiversity within arctic ecosystems, arctic foxes, vulpes lagopus, could serve as sentinels for the study of changes in the ecology of vector-borne zoonotic pathogens. the objective of this study was to determine the molecular prevalence of 5 different genera of vector borne pathogens (anaplasma, babesia, bartonella, ehrlichia, and hemotropic mycoplasma spp.) using blood collected from 28 live-trapped arctic foxes from the region of karrak lake, nunavut, canada. b ... | 2015 | 25596149 |
| estimating toxoplasma gondii exposure in arctic foxes (vulpes lagopus) while navigating the imperfect world of wildlife serology. | although the protozoan parasite toxoplasma gondii is ubiquitous in birds and mammals worldwide, the full suite of hosts and transmission routes is not completely understood, especially in the arctic. toxoplasma gondii occurrence in humans and wildlife can be high in arctic regions, despite apparently limited opportunities for transmission of oocysts shed by felid definitive hosts. arctic foxes (vulpes lagopus) are under increasing anthropogenic and ecologic pressure, leading to population declin ... | 2016 | 26745833 |
| benefiting from a migratory prey: spatio-temporal patterns in allochthonous subsidization of an arctic predator. | 1. flows of nutrients and energy across ecosystem boundaries have the potential to subsidize consumer populations and modify the dynamics of food webs, but how spatio-temporal variations in autochthonous and allochthonous resources affect consumers' subsidization remains largely unexplored. 2. we studied spatio-temporal patterns in the allochthonous subsidization of a predator living in a relatively simple ecosystem. we worked on bylot island (nunavut, canada), where arctic foxes (vulpes lagopus ... | 2012 | 22268371 |
