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

Dietary Response Of Sympatric Deer To Fire Using Stable Isotope Analysis Of Liver Tissue, W.D. Walter, T. J. Zimmerman, D. M. Leslie Jr., J. A. Jenks Dec 2009

Dietary Response Of Sympatric Deer To Fire Using Stable Isotope Analysis Of Liver Tissue, W.D. Walter, T. J. Zimmerman, D. M. Leslie Jr., J. A. Jenks

Natural Resource Management Faculty Publications

Carbon (δ13C) and nitrogen (δ15N) isotopes in biological samples from large herbivores identify photosynthetic pathways (C3 vs. C4 ) of plants they consumed and can elucidate potential nutritional characteristics of dietary selection. Because large herbivores consume a diversity of forage types, δ13C and δ15N in their tissue can index ingested and assimilated diets through time. We assessed δ13C and δ15N in metabolically active liver tissue of sympatric mule deer (Odocoileus hemionus) and white-tailed deer (O. virginianus) to identify dietary disparity resulting from use of burned and unburned areas in a largely forested landscape. Interspecific variation in dietary disparity of deer …

Nesting Ecology Of Greater Sage-Grouse Centrocercus Urophasianus At The Eastern Edge Of Their Historic Distribution, Katie M. Herman-Brunson, Kent C. Jensen, Nicholas W. Kaczor, Christopher C. Swanson, Mark A. Rumble, Robert W. Klaver Dec 2009

Nesting Ecology Of Greater Sage-Grouse Centrocercus Urophasianus At The Eastern Edge Of Their Historic Distribution, Katie M. Herman-Brunson, Kent C. Jensen, Nicholas W. Kaczor, Christopher C. Swanson, Mark A. Rumble, Robert W. Klaver

Natural Resource Management Faculty Publications

Greater sage-grouse Centrocercus urophasianus populations in North Dakota declined approximately 67% between 1965 and 2003, and the species is listed as a Priority Level 1 Species of Special Concern by the North Dakota Game and Fish Department. The habitat and ecology of the species at the eastern edge of its historical range is largely unknown. We investigated nest site selection by greater sage-grouse and nest survival in North Dakota during 2005 - 2006. Sage-grouse selected nest sites in sagebrush Artemisia spp. with more total vegetative cover, greater sagebrush density, and greater 1-m visual obstruction from the nest than at random …

Molt Migration By Giant Canada Geese In Eastern South Dakota, Charles D. Dieter, Bobby J. Anderson Oct 2009

Molt Migration By Giant Canada Geese In Eastern South Dakota, Charles D. Dieter, Bobby J. Anderson

Natural Resource Management Faculty Publications

We captured giant Canada geese (Branta canadensis maxima) in 7 counties in eastern South Dakota during the summer molting period, 2000–2003. We attached very high frequency (VHF) transmitters to 150 adult female geese with brood patches, and leg bands to 3,839 geese. We documented molt migrations using VHF telemetry and indirect band recovery at locations north of South Dakota. Telemetry of radio-collared female geese during the breeding season indicated that 56% of nonbreeders, 81% of unsuccessful breeders, and 19% of successful female breeders embarked on a molt migration. Five of 34 geese that underwent molt migrations moved to …

Planted Grasslands And Native Sod Prairie: Equivalent Habitat For Grassland Birds, Kristel K. Bakker, Kenneth F. Higgins Jan 2009

Planted Grasslands And Native Sod Prairie: Equivalent Habitat For Grassland Birds, Kristel K. Bakker, Kenneth F. Higgins

Natural Resource Management Faculty Publications

Little is known about how avian relationships to tracts of native sod prairie compare with avian relationships to single and multiple species of cool- and warm-season grassland plantings. We compared grassland bird species richness and density in 5 grassland cover types (n = 97) in the tallgrass prairie region of eastern South Dakota and western Minnesota, 2001–2004. Grassland bird species richness was significantly higher in native sod prairies than it was in all planted cover types except warm-season mixes. Grasslands dominated by exotic species did not support as many grassland bird species or have species densities as high as grasslands …

Natural Resource Management Faculty Publications

White-tailed deer (Odocoileus virginianus) mortalities (n = 4,433) caused by collisions with automobiles during 2003 were modeled in 35 counties in eastern South Dakota. Seventeen independent variables and 5 independent variable interactions were evaluated to explain deer mortalities. A negative binomial regression model (Ln Y = 1.25 – 0.12 [percentage tree coverage] + 0.0002 [county area] + 5.39 [county hunter success rate] + 0.0023 [vehicle proxy 96–104 km/hr roads], model deviance = 33.43, χ2 = 27.53, df = 27) was chosen using a combination of a priori model selection and AICc. Management options include use of the model to predict …

Seed Predators Of Canada Milk-Vetch And Their Parasitoids, Arvid Boe, Paul J. Johnson Jan 2008

Seed Predators Of Canada Milk-Vetch And Their Parasitoids, Arvid Boe, Paul J. Johnson

Native Plant Focused Publications

Canada milk-vetch (Astragalus canadensis L.), North America’s most widespread species of Astragalus, is important for herbivores and granivores in natural ecosystems but suffers heavy seed losses to bruchids and curculionids. Our objectives were: (1) compile a species inventory and describe life histories of insects associated with seed production in Canada milk-vetch, and (2) determine frequencies of pod predation and primary parasitism in Canada milk-vetch. The seed predators were Acanthoscelides perforatus (Horn) and Tychius liljebladi Blatchley. Frequency of pod predation varied between two plant populations (46 and 70%) and between A. perforatus (37 %) and T. liljebladi (21 %). The primary …

Seed Predation By Acanthoscelides Submuticus And A. Pallidipennis (Coleoptera: Bruchidae) In False Indigo In The Northern Great Plains, Arvid Boe, Paul J. Johnson

Native Plant Focused Publications

False indigo (Amorpha fruticosa L.) is a native North American leguminous shrub frequently found on shores of lakes and banks of rivers and streams in eastern and central United States and is present in 46 of the 48 contiguous states. It is planted for wildlife habitat, streambank erosion control, and ornamental purposes. Over several years, 16 collections of mature pods of false indigo were obtained from shorelines of four lakes and one cultivated planting in the northern Great Plains to determine frequency of pod predation by bruchid beetles. Frequency of pod predation by Acanthoscelides submuticus (Sharp) varied significantly among locations, …

Status, Distribution, And Density Of White-Tailed Jackrabbits And Black-Tailed Jackrabbits In South Dakota, Dustin J. Schaible Jan 2007

Status, Distribution, And Density Of White-Tailed Jackrabbits And Black-Tailed Jackrabbits In South Dakota, Dustin J. Schaible

Electronic Theses and Dissertations

The status of jackrabbit (Lepus spp.) populations throughout the Northern Great Plains has been a cause for concern by wildlife managers in recent years and there has been a paucity of information about the ecology of the white-tailed jackrabbit (Lepus townsendii) and the black-tailed jackrabbit (Lepus californicus) in South Dakota. Since there have been little monitoring efforts for hares, 21 permanent spotlight line transects were established across South Dakota for future surveying efforts. These transects were surveyed to obtain baseline information about jackrabbit density and distribution throughout the state. Jackrabbit density was highest in the northwestern portions of the state …

Diversity And Dominant Species Of Ground Beetle Assemblages (Coleoptera: Carabidae) In Crop Rotation And Chemical Input Systems For The Northern Great Plains, Michael M. Ellsbury, Janine E. Powell, Frank Forcella, W. David Woodson, Sharon A. Clay, Walter E. Riedell

Agronomy, Horticulture and Plant Science Faculty Publications

Dominant carabid species present in crops and crop rotation sequences commonly used in the northern Great Plains were assessed as an initial step toward the management of carabids as natural control agents. Ground beetle populations were determined by pitfall trapping in 4 crop rotation treatments maintained under high, managed, and low levels of chemical fertilizer and pesticide inputs. Diversity and species richness among crops, rotations, and input levels were compared using 3 indices—the Shannon-Weaver Index, relative diversity, and the Hierarchical Richness Index (HRI). Four carabid species, Cyclotrachelus altemans (Casey), Poecilvs lucublandus Say, Harpalns pensylvanicus (DeGeer), and Bembidion quadrimaculatum L., comprising …

Eastern South Dakota Wetlands, Rex R. Johnson, Kenneth F. Higgins, Michael L. Kjellsen, Charles R. Elliot Jan 1997

Eastern South Dakota Wetlands, Rex R. Johnson, Kenneth F. Higgins, Michael L. Kjellsen, Charles R. Elliot

Natural Resource Management Faculty Books

Diverse and extensive wetland resources have always been familiar parts of the landscape to farmers, hunters, and residents of eastern South Dakota. The journals and oral histories of adventurers, trappers, and natives and immigrants reveal how wetlands shaped the wildlife and the people who lived on and modified the land to meet their own needs. The history of South Dakota wetlands parallels the history and interactions of people and wetlands elsewhere in North America and the world. This interaction can best be characterized as constant conflict. Driven primarily by economics, farmers the world over expended tremendous energy to "reclaim" and …

Wetland Resources Of Eastern South Dakota, Rex R. Johnson, Kenneth F. Higgins Jan 1997

Wetland Resources Of Eastern South Dakota, Rex R. Johnson, Kenneth F. Higgins

Natural Resource Management Faculty Books

The mere mention of the word "wetland" in coffee shops and other gathering places on the prairies today brings out emotions and opinions that run the gamut from saving them all to draining them all. To some people, what we do with wetlands has been, and still is, a personal choice, a matter of exercising individual rights on private property. To others, wetlands are community resources that provide values that touch all of society. They contend that what is done to and about wetlands is a community decision regardless of ownership. Herein lies the controversy we have experienced over wetlands …
