Prenatal Infection of Bighorn Sheep with Protostrongylid Lungworms
Nature, 1964PROTOSTRONGYLID lung nematodes are world-wide in distribution1, and have been found to influence seriously the health and productivity of domestic animals2 and may effectively control populations of wild animals3,4. Although it is felt that protostrongylids require land snails as intermediate hosts5,6, all aspects of infection of the final host by ...

Founder effect in an island population of bighorn sheep
Molecular Ecology, 2001AbstractThe Tiburon Island population of desert bighorn sheep has increased in size from 20 founders in 1975 to approximately 650 in 1999. This population is now the only population being used as the source stock for transplantations throughout northern Mexico. To evaluate the genetic variation in this population, we examined 10 microsatellite loci and

Pasteurellaceae from Colorado Bighorn Sheep Herds
Journal of Wildlife Diseases, 2011We compared phenotypic and genotypic characterizations of 88 Pasteurellaceae isolates from bighorn sheep (Ovis canadensis) in the course of exploring epizootiologic relationships. Based on our observations, adopting contemporary taxonomic conventions and using molecular methods to detect and compare Pasteurellaceae may help improve understanding of ...

Foraging behaviour and sexual segregation in bighorn sheep
Animal Behaviour, 1998Like many sexually dimorphic ungulates, bighorn sheep, Ovis canadensis, form sexually segregated groups. Nursery groups include females, lambs and subadult males, while adult males form bachelor groups. Previous hypotheses to account for sexual segregation in ungulates have suggested sexual differences in energy requirements, predation risk and social ...
