A Paleoecologic Perspective On Past Plant Invasions In Yellowstone, Cathy Whitlock, Sarah H. Millspaugh

Western North American Naturalist

The role of climate and natural disturbance in the past provides a context for understanding present and future changes in biota. The vegetation history of the Yellowstone region, like that of North America as a whole, is largely one of plant invasions and extinctions in response to changes in climate and environment. When Holocene plant migrations are examined on multiple spatial and temporal scales, several generalities are apparent. First, at a continental and regional scale, plant migration patterns followed the direction of climate change, whereas at local scales plant colonization was governed by site-specific conditions and possibly by biotic interactions. …

What Is Natural? Philosophical Analysis And Yellowstone Practice, Paul Schullery

Western North American Naturalist

The following remarks were Paul Schullerys introduction to a roundtable discussion presented during the 5th Biennial Scientific Conference on the Greater Yellowstone Ecosystem, held 11–13 October 1999 in Yellowstone National Park. His remarks serve a second purpose in this issue of the WESTERN NORTH AMERICAN NATURALIST, as they set the stage for and introduce the remaining articles, all of which are papers, presentations, or addresses from that conference. The 1999 Yellowstone Biennial Conference was entitled "Exotic Organisms in Greater Yellowstone: Native Biodiversity Under Siege." Mr. Schullery is a resource naturalist with the National Park Service in Yellowstone.

Natural And Unnatural; Wild And Cultural, Holmes Rolston Iii

Western North American Naturalist

Yellowstone National Parks mission and policy can be clarified by analysis of the natural and the unnatural. Nature is a comprehensive word, in some uses excluding nothing; more useful is a contrast distinguishing nature and culture. Specifying "wild nature" denotes spontaneous nature absent human influence. Critics claim that the meaning of wild nature, especially of wilderness, is a foil of culture. Pristine nature, often romanticized, is contrasted with a technological and industrial culture. By this account, wilderness is a social construction.

Nevertheless, wild nature successfully denotes, outside culture, an evolutionary and ecological natural history, which remains present on the Yellowstone …

Effects Of Exotic Species On Yellowstone's Grizzly Bears, Daniel P. Reinhart, Mark A. Haroldson, David J. Mattson, Kerry A. Gunther

Western North American Naturalist

Humans have affected grizzly bears (Ursus arctos horribilis) by direct mortality, competition for space and resources, and introduction of exotic species. Exotic organisms that have affected grizzly bears in the Greater Yellowstone Area include common dandelion (Taraxacum officinale), nonnative clovers (Trifolium spp.), domesticated livestock, bovine brucellosis (Brucella abortus), lake trout (Salvelinus namaycush), and white pine blister rust (Cronartium ribicola). Some bears consume substantial amounts of dandelion and clover. However, these exotic foods provide little digested energy compared to higher-quality bear foods. Domestic livestock are of greater energetic value, but …

Mountain Goats In The Greater Yellowstone Ecosytem: A Prehistoric And Historical Context, Paul Schullery, Lee Whittlesey

Western North American Naturalist

Because the relatively recent colonization of portions of Yellowstone National Park by introduced mountain goats (Oreamnos americanus) from public game lands in Montana raises important policy and management questions for the park, it is necessary to understand the prehistoric and early historical record of mountain goats in the Greater Yellowstone Ecosystem. We reviewed previous paleontological, archeological, and historical studies of goat presence and examined a large body of historical material for evidence of goats. Native mountain goat range most closely approached the Greater Yellowstone Ecosystem to the west, but no modern authority claims goats were resident in the …

Biological Invasions—How Are They Affecting Us, And What Can We Do About Them?, Daniel Simberloff

Western North American Naturalist

Nonindigenous species affect native ecosystems, communities, and populations in myriad ways, from plants (and a few animals) that overgrow entire communities, to plants and animals that hybridize individual native species to a sort of genetic extinction. Further, nonindigenous species sometimes interact to worsen each others impact. These impacts are commonly seen in national parks throughout the United States. The key policy change required to alleviate this threat is a shift from blacklists of prohibited species and a presumption of harmlessness to combinations of white and blacklists and a presumption that any species may be damaging. This new guiding philosophy must …

Managing A Complex Exotic Vegetation Program In Yellowstone National Park, Tom Olliff, Roy Renkin, Craig Mcclure, Paul Miller, Dave Price, Dan Reinhart, Jennifer Whipple

Western North American Naturalist

The number of documented exotic plants in Yellowstone National Park has increased from 85 known in 1986 to over 185 today. Exotic plants are substantially impacting the parks natural and cultural resources and are a high management priority. We have adopted an integrated weed management approach with regard to exotic vegetation, emphasizing prevention, education, early detection and eradication, control, and, to a lesser degree, monitoring. The program involves over 140 staff with program expenditures averaging approximately $190,000 annually. Prevention actions include requiring approved gravel on construction projects; banning hay in the backcountry and allowing transport of only certified weed-seed-free hay …

Determination Of 4,4′-Dinitrocarbanilide (Dnc), The Active Component Of The Antifertility Agent Nicarbazin, In Chicken, Duck, And Goose Plasma, Thomas M. Primus, Dennis J. Kohler, Margaret A. Goodall, Christi Yoder, Doreen Griffin, Lowell A. Miller, John J. Johnston

United States Department of Agriculture Wildlife Services: Staff Publications

4,4′-Dinitrocarbanilide (DNC) was extracted from chicken, duck, and goose plasma and isolated by reversed-phase high-performance liquid chromatography. DNC was detected by ultraviolet absorbance at 347 nm and quantified by comparison to a calibration standard. Recovery data were determined by analyzing DNC-fortified control plasma. The mean recovery of DNC in fortified chicken plasma samples was 99.7 ± 1.9% for 0.18 and 9.1 ppm DNC, and in fortified duck and goose plasma samples was 99.5 ± 4.9% and 101.4 ± 4.5%, respectively, for 0.18, 9.1, and 18 ppm DNC.

Diets Of Wild Versus Released, And Pen-Raised White-Tailed Deer In Southeastern Louisiana, Richard James Meyers

LSU Historical Dissertations and Theses

Twenty pen-raised white-tailed deer (Odocoileus virginianus) were released into mixed pine-hardwood forest habitat in southeastern Louisiana to compare their seasonal diets to the diets of the wild white-tailed deer population. Microhistological analysis was used to estimate the botanical composition of fecal pellet samples collected from both populations of deer over four consecutive seasons. Wild and pen-raised deer diets were found to be an average of 75.18% similar during the entire year of the study, and were significantly associated during all seasons (P < 0.001), indicating that all deer foraged on similar plant taxa in similar proportions regardless of season. Both populations of deer were found to be predominantly browsers during all seasons, with browse and fruit accounting for a yearly average of >55% of deer diets. Results from this study indicate that rehabilitated or translocated deer released into new environments …

Univercity News (2001-07-23)

UniverCity News, 1998-2001

VCU Today, the University’s first official administrative organ, began as a somewhat irregular monthly publication but moved to a bi-weekly newspaper format in the 1980s. The newspaper changed its name to VCU Voice in 1988 and ten years later it appeared under the title UniverCity News. As it neared the end of its run as a physical newspaper, the publication became simply VCU News. These four publications were essentially the same periodical published under different titles by the Office of University Relations. VCU News appeared online for the first time in 2002.
