| the prevalence of serum antibodies to toxoplasma gondii in ontario mammals. | the prevalence of seropositive reactions to toxoplasma gondii was studied in farm animals, companion animals, wild rodents and birds. of the animals tested, 17% of cattle, 65% of sheep, 45% of pigs, 9% of horses, 33% of dogs and 20% of cats were seropositive by the sabin-feldman dye test. in addition 11% of mice (mus musculus), 5% of deer mice (peromyscus), 3% of rats (rattus norvegicus) and less than 2% of sparrows (passer domestcus) were seropositive. all samples from short-tailed field mice ( ... | 1978 | 667705 |
| determinants of population genetic structure in eastern chipmunks (tamias striatus): the role of landscape barriers and sex-biased dispersal. | dispersal and gene flow are important processes affecting the evolutionary potential of wild populations. assessing the importance of such patterns is thus critical, especially in contexts where environmental attributes may enhance or restrict the movements of individuals across patchy habitats. a landscape genetics approach is effective in that respect as it combines spatial and genetic data to identify landscape features that play a role in shaping genetic structure. the primary objective of o ... | 2010 | 20219886 |
