Rattlesnake predation on desert rodents: microhabitat and species-specific effects on risk
Article Abstract:
Four species of desert rodents were tested for risk of Great Basin rattlesnake (Crotalus viridis lutosus) predation. These are the two bipedal rodent species, Dipodomys merriami and Microdipodops megacephalus and the two quadrupedal rodent species, Perognathus parvus and Peromyscus maniculatus. D. merriami and P. maniculatus are good in avoiding rattlesnakes, but M. megacephalus and P. parvus are often caught. Locomotion type has no significant effect on risk of snake predation. A general lack of rattlesnake predation in the Great Basin has led to relaxation of anti-snake behavior in rodent species restricted to this area.

Hunting associations between badgers (Taxidea taxus) and coyotes (Canis latrans)
Article Abstract:
Badger-coyote (Taxidea taxus-Canis latrans) hunting associations have greater successes in hunting for Uinta ground squirrels (Spermophilus armatus). Coyotes, hunting alone, are impeded by brushes. Badgers drive squirrels out of their burrows. Coyotes and badgers have complementary morphological adaptations and predatory strategies, social behaviors and interspecific tolerance for combined pursuit of ground-dwelling squirrels, and the association benefits both species. The short-term mutualistic behaviors of both species are geared toward individual prey capture.

Scent-marking by coyotes, Canis latrans: the influence of social and ecological factors
Article Abstract:
Scent-marking in coyotes, Canis latrans, seems to serve to supply internal information to members of a resident pack and to boost demarcation of territorial boundaries. Research undertaken among 49 coyotes in the Lamar River Valley, Yellowstone National Park, WY, established that the factors determining the rate of scent-marking through urination are influenced by social class, social organization and the time of year. The research seems to indicate that the coyote social system is quite flexible.
