| risk factors associated with prevalence of antibodies to leptospira interrogans in a metapopulation of black-tailed prairie dogs in mexico. | interest in the study of infectious diseases of wildlife has grown in recent decades and now focuses on understanding host-parasite dynamics and factors involved in disease occurrence. the black-tailed prairie dog (cynomys ludovicianus) is a useful species for this type of investigation because it lives in heterogeneous landscapes where human activities take place, and its populations are structured as a metapopulation. our goal was to determine if colony area, density, and proximity to human se ... | 2015 | 25380365 |
| rapid response of a grassland ecosystem to an experimental manipulation of a keystone rodent and domestic livestock. | megaherbivores and small burrowing mammals commonly coexist and play important functional roles in grassland ecosystems worldwide. the interactive effects of these two functional groups of herbivores in shaping the structure and function of grassland ecosystems are poorly understood. in north america's central grasslands, domestic cattle (bos taurus) have supplanted bison (bison bison), and now coexist with prairie dogs (cynomys spp.), a keystone burrowing rodent. understanding the ecological re ... | 2010 | 21141180 |
