Corn Hybrids: Deer Taste The Difference, Joshua A. Delger, Kevin L. Monteith, Jonathan A. Jenks Dec 2010

Corn Hybrids: Deer Taste The Difference, Joshua A. Delger, Kevin L. Monteith, Jonathan A. Jenks

Natural Resource Management Faculty Publications

As daylight begins to illuminate the countryside, a cold wind rustles through the leaves of the weedy rows of corn that you barely had time to get in the ground this past spring. The corn plants are stunted, the few small ears of corn that did grow are not even enticing to passing blackbirds, and that stud buck captured on your trail-camera months earlier is nowhere to be seen. Meanwhile, a couple hundred yards across the fence to the south, you hear the unmistakable sound of deer running through corn. Your heart rate involuntarily increases. As the sun continues to …


Late Summer Movements By Giant Canada Geese In Relation To A September Hunting Season, Charles D. Dieter, Bobby J. Anderson, Jeffrey S. Gleason, Paul W. Mammenga, Spencer Vaa Oct 2010

Late Summer Movements By Giant Canada Geese In Relation To A September Hunting Season, Charles D. Dieter, Bobby J. Anderson, Jeffrey S. Gleason, Paul W. Mammenga, Spencer Vaa

Natural Resource Management Faculty Publications

The population of giant Canada geese (Branta canadensis maxima) breeding in eastern South Dakota has increased dramatically since reintroduction efforts began in the 1960s. May breeding population levels of giant Canada geese exceeded population management goals set by the South Dakota Department of Game, Fish and Parks (SDGFP) by the mid-1990s, and the population has continued to increase into the 2000s. This population increase was accompanied by an increase in goose-related conflicts such as crop depredation. In 1996, a September hunting season was implemented in select counties in eastern South Dakota in an effort to reduce the giant …


Dispersal Movements Of Subadult Cougars From The Black Hills: The Notions Of Range Expansion And Recolonization, D. J. Thompson, J. A. Jenks Oct 2010

Dispersal Movements Of Subadult Cougars From The Black Hills: The Notions Of Range Expansion And Recolonization, D. J. Thompson, J. A. Jenks

Natural Resource Management Faculty Publications

Dispersal plays a vital role in cougar (Puma concolor) population ecology, creating genetic viability and maintaining gene flow between populations. The naturally recolonized cougar population in the Black Hills is at the edge of the species’ range in North America and completely surrounded by the grasslands of the Northern Great Plains. Our objective was to document dispersal movements and possible range expansion of subadult cougars captured within the Black Hills ecosystem of southwestern South Dakota and eastern Wyoming. Twenty-four (n ¼ 14 males, n ¼ 10 females) subadult cougars were captured in the Black Hills. Independence of cougars from females …


Survival And Harvest Characteristics Of Giant Canada Geese In Eastern South Dakota, 2000–2004, Charles D. Dieter, Jeffrey S. Gleason, Bobby J. Anderson, Spencer Vaa, Paul W. Mammenga Oct 2010

Survival And Harvest Characteristics Of Giant Canada Geese In Eastern South Dakota, 2000–2004, Charles D. Dieter, Jeffrey S. Gleason, Bobby J. Anderson, Spencer Vaa, Paul W. Mammenga

The population of giant Canada geese (Branta canadensis maxima) in eastern South Dakota has increased substantially since reintroduction efforts began in the 1960s. Breeding population estimates of Canada geese exceeded the population management objective of the South Dakota Game, Fish and Parks by the mid-1990s and has continued to increase at an estimated rate of 3 to 5% per year. Goose-related crop damage complaints have also increased. In 1996, a September hunting season (September 1 to 15) was implemented in 10 counties in eastern South Dakota and was expanded in 2000 to include most of eastern South Dakota. …


Antipredatory Defense Of Neonatal Pronghorn (Antilocapra Americana) By Yearling Male Pronghorn In Southwestern South Dakota, Christopher N. Jacques, Jonathan A. Jenks Jan 2010

Antipredatory Defense Of Neonatal Pronghorn (Antilocapra Americana) By Yearling Male Pronghorn In Southwestern South Dakota, Christopher N. Jacques, Jonathan A. Jenks

Natural Resource Management Faculty Publications

Antipredatory defense of pronghorn (Antilocapra americana) neonates (≤1 month old) by adult females (>18 months old) is well documented throughout the geographic range of this species. However, reports of male pronghorn defending neonates against predators are limited to a single study in northwestern Wyoming where occurrences were documented of adult males assisting female pronghorn in defending neonates against coyotes (Canis latrans). To our knowledge, defense of neonatal pronghorn by yearling males (12–18 months old) has not been reported previously for this species. We report occurrences of antipredatory defense of neonatal pronghorn by yearling males in southwestern South Dakota
