Genetic Diversity And Low Reproductive Success In Isolated Populations Of Utah Juniper (Juniperus Osteosperma, Cupressaceae), Loreen Allphin, Val J. Anderson, Amy F. Hunt

Faculty Publications

Utah juniper (Juniperus osteosperma) has greatly expanded its historical range in the western United States. Management plans for the species have focused on curtailing its encroachment into sagebrush and grassland communities. These plans often include burning or other methods of elimination. These methods may result in subdivision or fragmentation of existing juniper stands. We initiated a study at Dugway Proving Ground, a U.S. Army facility, to examine the effects of fragmentation on the reproductive success of Utah juniper in isolated populations. We used enzyme electrophoresis to quantify genetic variability in isolated populations. We also determined population reproductive success by examining …

Evaluating Diet Composition Of Pronghorn In Wind Cave National Park, South Dakota, Christopher N. Jacques, Jaret D. Sievers, Jonathan A. Jenks, Chad L. Sexton, Daniel E. Roddy

The Prairie Naturalist

The pronghorn (Antilocapra americana) was reintroduced into Wind Cave National Park (WCNP), South Dakota, in 1914, and thus, has inhabited the Park for nearly a century. During the 1990's, a decline in the population raised concern for the continued existence of pronghorn inside WCNP; an investigation into the observed decline was initiated. Primary objectives of our study were to evaluate diet composition and forage selection by pronghorn in WCNP. Microhistological analysis was conducted on 58 fecal samples collected opportunistically from pronghorn during 2002. Blue grama (Bouteloua gracilis), common juniper (Juniperus communis), and northern bedstraw …

Feeding And Managing Sheep In Dry Times, Ian Mcfarland, Mandy Curnow, Mike Hyder, Brian Ashton, Danny Roberts

Bulletins 4000 -

Feeding sheep is a significant cost to any sheep or mixed farm enterprise in southern Australia. The cost is usually managed by annually sourcing feed on-farm. However, this feed source can become scarce when we experience unusual dry spells within seasons (termed a 'dry season', such as a dry winter or spring), a late break to the season, a drought year, or even worse, successive drought years.

Climate change research suggests that southern Australia will experience higher annual temperatures and a decline in mean growing season rainfall (particularly winter and spring) over the coming decades. This will affect the productivity …

Amphibians And Reptiles In A Mixed-Grass Prairie In Northwestern North Dakota, Robert K. Murphy, Robert F. Danley, Patricia K. Moore

The Prairie Naturalist

There have been almost no surveys of herpetofauna at 109 km² Lostwood National Wildlife Refuge (LNWR) or surrounding counties in northwestern North Dakota, an area possibly undergoing significant environmental change from fossil fuel extraction and use. We used 30 m drift fences to survey amphibian and reptile species in prairie-wetland transition zones at LNWR during mid-May to early-July in 1985 to 1987, and again in 1999 and 2000. We captured only four amphibian and two reptilian species and noted one other reptilian species incidental to our survey. Several species expected to occur in the area were not detected.

Development Of Pcr-Based Chloroplast Dna Markers That Characterize Domesticated Cowpea (Vigna Unguiculata Ssp. Unguiculata Var. Unguiculata) And Highlight Its Crop-Weed Complex, Y. Feleke, R. S. Pasquet, P. Gepts

All Peer-Reviewed Publications

In 1992, Vaillancourt and Weeden discovered a very important mutation for studying cowpea evolution and domestication. A loss of a BamHI restriction site in chloroplast DNA characterized all domesticated accessions and a few wild (Vigna unguiculata ssp. unguiculata var. spontanea) accessions. In order to screen a larger number of accessions, primers were designed to check this mutation using PCR RFLP or direct PCR methods. Using these new primers, 54 domesticated cowpea accessions and 130 accessions from the wild progenitor were screened. The absence of haplotype 0 was confirmed within domesticated accessions, including primitive landraces from cultivar-groups Biflora and Textilis, suggesting …

Habitat Characteristics Of Spring Blackbird Roosts In East-Central South Dakota, H. Jeffrey Homan, Richard S. Sawin, George M. Linz, William J. Bleier

The Prairie Naturalist

In the northern Great Plains, blackbirds (Icteridae) roost almost exclusively in emergent-dominated wetlands. The physical characteristics of wetland roosts are not well understood. From March 20 to April 20, 1999, we studied 16 wetlands used as blackbird roosts in east-central South Dakota. Six wetlands had major roosts (range: 102,000-298,000 blackbirds); whereas, 10 wetlands had minor roosts (range: 2,010-34,000 blackbirds). Maximum roost size was correlated directly with emergent vegetation area (P = 0.05) and possibly with wetland basin area (P ≤ 0.10). Water depths were greater at used sites within wetlands of major roosts (median = 44 cm) than …

Combined Control Of Striga Hermonthica And Stemborers By Maize-Desmodium Spp. Intercrops, Zeyaur R. Khan, John A. Pickett, Lester J. Wadhams, Ahmed Hassanali, Charles A.O. Midega

All Peer-Reviewed Publications

The African witchweed (Striga spp.) and lepidopteran stemborers are two major biotic constraints to the efficient production of maize in sub-Saharan Africa. Previous studies had shown the value of intercropping maize with Desmodium uncinatum in the control of both pests. The current study was conducted to assess the potential role of other Desmodium spp., adapted to different agro-ecologies, in combined control of both pests in Kenya. Treatments consisted of intercropped plots of a Striga hermonthica- and stemborer-susceptible maize variety and one Desmodium sp. or cowpea, with a maize monocrop plot included as a control. S. hermonthica counts and stemborer damage …

Artificial Burrows And The Deer Mouse: Do Number Of Entrances Influence Use?, Glennis A. Kaufman, Donald W. Kaufman

The Prairie Naturalist

We examined use of artificial burrows by the deer mouse (Peromyscus maniculatus) in mixed grass prairie in north central Kansas. We predicted differential use of burrows, such that the deer mouse would prefer two entrance burrows in non-winter months when predatory snakes were active, but prefer one entrance burrows in winter when cold, windy conditions existed. We installed 20 pairs of artificial burrows (one single entrance and one double entrance) in summer 1988. We examined these burrows on seven dates from autumn 1988 to autumn 1989. All mice (n = 70) used two entrance burrows at least …

Invasive Species Definition Clarification And Guidance, Invasive Species Advisory Committee

National Invasive Species Council

Summary

Invasive species are those that are not native to the ecosystem under consideration and that cause or are likely to cause economic or environmental harm or harm to human, animal, or plant health. Plant and animal species under domestication or cultivation and under human control are not invasive species. Furthermore for policy purposes, to be considered invasive, the negative impacts caused by a non-native species will be deemed to outweigh the beneficial effects it provides. Finally, a non-native species might be considered invasive in one region but not in another. Whether or not a species is considered an invasive …

Estimates Of Breeding Bird Populations In The Sheyenne National Grassland, North Dakota, Mary Ann Cunningham, Douglas Johnson, Daniel N. Svingen

The Prairie Naturalist

We conducted a two-year survey of breeding birds in the Sheyenne National Grassland, North Dakota, to estimate total populations of breeding birds. The Grassland is of interest because it provides wildlife habitat and recreational birding opportunities. Indicated breeding pairs were counted on 100-m wide belt transects during morning surveys from late May to early July in 2002 and 2003. We surveyed approximately 6 to 7% of the Grassland each year. The most abundant species in both years were grasshopper sparrow (Ammodramus savannarum), red-winged blackbird (Agelaius phoeniceus), claycolored sparrow (Spizella pallida), Savannah sparrow (Passerculus …

Effects Of Predator Removal On Upland Nesting Ducks In North Dakota Grassland Fragments, Kristen D. Chodachek, Michael J. Chamberlain

The Prairie Naturalist

Low nest success rates in the Prairie Pothole Region are attributed mainly to changes in the predator community coupled with reductions in availability of suitable nesting cover. We evaluated effects of removal of mammalian predators on pair density and nest success of ducks nesting on 259 ha sites in northeastern North Dakota during 2001 and 2002. We monitored pair density and duck nests on 10 sites with removal and 10 sites without removal. Overall nest success for both years was greater on trapped (53.4%) than nontrapped sites (28.7%). Pair densities were not affected by predator removal, but did increase across …

Fire History, Passerine Abundance, And Habitat On A North Dakota Drift Plain Prairie, Timothy J. Ludwick, Robert K. Murphy

The Prairie Naturalist

Prescribed fire is among key tools for restoring and managing prairies in the northern Great Plains, yet there are no published reports of its impacts on grassland passerine birds on native prairie in the Drift Plain, a major physiographic subregion. We examined relationships between prescribed fire history and abundance and habitat of breeding passerines in Drift Plain prairie at Des Lacs National Wildlife National Refuge in northwestern North Dakota. In 2003, we used point counts (n = 79 75 m radius plots) to survey bird abundance on 16 management units that had been prescribe-burned one to three times each …

Evolution Of The Nanog Pseudogene Family In The Human And Chimpanzee Genomes, Daniel J. Fairbanks, Peter J. Maughan

Faculty Publications

The NANOG gene is expressed in mammalian embryonic stem cells where it maintains cellular pluripotency. An unusually large family of pseudogenes arose from it with one unprocessed and ten processed pseudogenes in the human genome. This article compares the NANOG gene and its pseudogenes in the human and chimpanzee genomes and derives an evolutionary history of this pseudogene family. Results: The NANOG gene and all pseudogenes except NANOGP8 are present at their expected orthologous chromosomal positions in the chimpanzee genome when compared to the human genome, indicating that their origins predate the human-chimpanzee divergence. Analysis of flanking DNA sequences demonstrates …

Forage Systems For Minimizing Hay And Concentrate Feed Needs, Glen E. Aiken

Forage Symposium at the Kentucky Cattlemen’s Convention

Cattlemen typically simplify their pasture management by relying on one or two forages that are well adapted and persist under their targeted levels of management and production. The 5.5 million acres of Kentucky-31 tall fescue in Kentucky is a strong indication how producers in the state rely on the cool-season perennial grass, sometimes in mixture with red or white clover, to meet their grazing needs. An advantage of this approach is that fertilization and grazing management is based on a single growth distribution and set of fertilizer needs. Disadvantages are that yield, growth distribution, and quality of forage may not …

How Good Is Your Hay?, Tom Keene

Forage Symposium at the Kentucky Cattlemen’s Convention

All hay that is made or produced should have a value placed on it. Because no matter what livestock enterprise that it is earmarked for, there were significant inputs that went into producing that hay. Therefore, it is imperative that we place a value on the hay product(s) that we have produced.

New Developments In Pasture Weed Control, William W. Witt

Forage Symposium at the Kentucky Cattlemen’s Convention

Weeds in pastures continue to offer challenges to the producer for controlling these unwanted plants. The combination of forage grasses grown in pastures and the climate of Kentucky provides an environment that is conducive for having numerous weedy species. Most pastures have a combination of cool season (those that begin growth in fall and mature in spring or early summer) and warm season (those that begin growth in spring and mature in late summer or fall) weeds. Additionally, some weeds such as thistles severely restrict grazing while other weeds do not. The decision to apply a weed management strategy is …

Roundup Ready® Alfalfa, Novel Endophyte Tall Fescue, Red And White Clover, Bermudagrass, And More, S. Ray Smith

Forage Symposium at the Kentucky Cattlemen’s Convention

Finally, Roundup Ready® alfalfa is now available and currently varieties show excellent tolerance to Roundup, good disease res i stance, and good yield potential. Before making plans to plant 100 acres know that the price in most states is over $7.00 per pound and pre-ordering seed is essential if you want to plant the spring of 2006. Roundup tolerance is a very useful trait in alfalfa, but remember that Roundup Ready ® varieties are not superior for other traits. Some current advertisement s promote Roundup Ready® varieties as higher yielding and higher quality. These statements are not untrue, but they …

Using Legumes To Renew Grass Pastures, Garry D. Lacefield

Forage Symposium at the Kentucky Cattlemen’s Convention

Legume content in Kentucky pastures has been reduced dramatically as a result of the drought and high temperatures of 2005 and very muddy conditions this past winter. In addition, late-winter early-spring seedings during 2004 were not as successful as normal due to excessive moisture during the establishment periods. As a result of our reduced amount of legumes in pasture and the many advantages legumes have for improving Kentucky pastures, serious considerations should be given to renovating pastures in 2006.

Terpenes And Carbohydrate Source Influence Rumen Fermentation, Digestibility, Intake, And Preference In Sheep, J. J. Villalba, F. D. Provenza, K. C. Olson

Green Canyon Environmental Research Area, Logan Utah

We hypothesized that toxins and nutrients in foods interact to influence foraging behavior by herbivores. Based on this hypothesis we predicted that 1) terpenes in big sagebrush (Artemisia tridentata) influence intake and preference in sheep for diets varying in sources of nonstructural (barley grain) and structural (sugar beet pulp) carbohydrates, and 2) these effects are due to the differential effects of terpenes on fermentation products and apparent digestibility of each class of carbohydrates. Lambs were fed 2 isoenergetic and isonitrogenous diets with varying proportions of the same ingredients (beet pulp- and barley grain-based diet) or offered a choice between the …

The Vertebrate Fauna Of The Upper Permian Of Niger. Iv. Nigerpeton Ricqlesi (Temnospondyli: Cochleosauridae), And The Edopoid Colonization Of Gondwana, J. Sebastien Steyer, Ross Damiani, Christian A. Sidor, F. Robin O’Keefe, Hans C.E. Larsson, Abdoulaye Maga, Oumarou Ide

Biological Sciences Faculty Research

We describe the edopoid temnospondyl Nigerpeton ricqlesi from the Upper Permian Moradi Formation of northern Niger on the basis of two partial skulls and tentatively associated postcranial material. This crocodile-like taxon displays several edopoid characters states such as a long prenarial region with enlarged premaxillae, elongated vomers, large, posteriorly tapering choanae, and a jugal that broadens anteriorly. Nigerpeton possesses a unique carnivorous dentition. It is autapomorphic in its possession of an extremely elongate snout bearing a maxillary bulge that accommodates three hypertrophied caniniform teeth, inner premaxillary tusks, and anterior paired fenestrae, which pierce the skull roof. In addition, both the …
