Elevation and vegetation determine Cryptosporidium oocyst shedding by yellow-bellied marmots (Marmota flaviventris) in the Sierra Nevada Mountains
Wildlife are increasingly recognized as important biological reservoirs of zoonotic species of Cryptosporidium that might contaminate water and cause human exposure to this protozoal parasite. The habitat range of the yellow-bellied marmot (Marmota flaviventris) overlaps extensively with the watershed boundaries of municipal water supplies for California communities along the foothills of the S...
متن کاملEnergetics of hibernating yellow-bellied marmots (Marmota flaviventris).
Yellow-bellied marmots (Rodentia: Sciuridae) typically hibernate for eight months. This study explored energetic costs of hibernation in young and adults at 10 and 6 degrees C. Age significantly affected the percent time torpid, total and mass-specific VO(2), use of energy during torpor, and daily mass loss at 6 degrees C. Thus young had a higher mass-specific VO(2) during a torpor bout, which ...
متن کاملGroup size affects social relationships in yellow-bellied marmots (Marmota flaviventris)
Demographic variation, such as changes in population size, affects group-living conditions and thus creates new opportunities for individuals to interact socially. To understand how this variation in the social environment affects social structure, we used social network analysis to explore affiliative behaviors of nonpup (i.e., 1 year or older), female, yellow-bellied marmots (Marmota flaviven...
متن کاملEarly play may predict later dominance relationships in yellow-bellied marmots (Marmota flaviventris).
Play has been defined as apparently functionless behaviour, yet since play is costly, models of adaptive evolution predict that it should have some beneficial function (or functions) that outweigh its costs. We provide strong evidence for a long-standing, but poorly supported hypothesis: that early social play is practice for later dominance relationships. We calculated the relative dominance r...
متن کاملThe Effect of Molt on Oxygen Consumption of Yellow-bellied Marmots (marmota Flaviventris)
l. Mean specific fro, of five adult female yellow-bellied marmots was significantly lower in postmolt individuals than in premolt animals. 2. Mean body temperature did not differ significantly between premolt and postmolt marmots. 3. Conductance was significantly lower in postmolt than in premolt marmots. 4. &cause body mass was significantly larger and total 00, significantly lower in postmolt...
