Health And Fertility Implications Related To Seasonal Changes In Kidney Fat Index Of White-Tailed Jackrabbits In South Dakota, Dustin Schaible, Charles D. Dieter
Great Plains Research: A Journal of Natural and Social Sciences
White-tailed jackrabbit (Lepus townsendii) populations in the Northern Plains have been in a general decline for the past decade or longer. A suggested reason for this population decline was reduced body condition of individual jackrabbits due to habitat changes. In order to evaluate body condition, we determined the kidney fat index of 314 white-tailed jackrabbits harvested in 44 counties throughout South Dakota. We removed and weighed kidneys and all perirenal fat associated with the kidneys from collected jackrabbits. We measured kidney weight to determine times of high metabolic activity as indicated by an increase in mass. Body condition was …

Originally carved out by a receding glacier during the Wisconsin glaciations, for its entire history the lake has gone dry during low precipitation -- a cycle interrupted after the Bureau of Indian Affairs (BIA) commissioned several artesian wells beginning in 1896. As the lake expanded, the U.S. Fish Commission …
