Occurrences Of Small Mammal Species In A Mixedgrass Prairie In Northwestern North Dakota,, Robert K. Murphy, Richard A. Sweitzer, John D. Albertson

The Prairie Naturalist

Documentation is limited for many species of vertebrates in the northern Great Plains, particularly northwestern North Dakota (Bailey 1926, Hall 1981). Here we report relative abundances of small « 450 g) species of mammals that were captured incidental to surveys of amphibians and reptiles at Lostwood National Wildlife Refuge (LNWR) in northwestern North Dakota from 1985 to 1987 and 1999 to 2000. Our records include a modest range extension for one species. We also comment on relationships of small mammals on the refuge to vegetation changes associated with fire and grazing disturbances.

First Record Of Corisella Inscripta (Uhler) (Heteroptera: Corixidae) From North Dakota, Bruce A. Hanson, David M. Mushet, Ned A. Euliss Jr., Stephen Chordas Iii

The Prairie Naturalist

Corisella inscripta is a water boatman species that was reported in H. B. Hungerford's (1948) seminal monograph as occurring throughout Mexico and nine western states of the United States. Subsequently, additional records of C. inscripta have been reported for British Columbia in Canada (Maw et al. 2000) and for Montana (Roemhild 1976), Arkansas (Cochran and Harp 1990), Missouri (Polhemus et al. 1988), Ohio (Chordas and Armitage 1998), and Michigan (Chordas et al. 2002) in the United States. There have been no published records of C. inscripta from North Dakota (Fig. I). We collected one male C. inscripta at the Cottonwood …

Review Of Some Scarce Birds Of The Upper Midwest By Dana Gardner And Nancy Overcott, Stephen J. Dinsmore

The Prairie Naturalist

Fifty Uncommon Birds of the Upper Midwest. Watercolors by Dana Gardner; text by Nancy Overcott. 2007. University of Iowa Press, Iowa City, Iowa. 112 pages. $34.95 (cloth).

Nancy Overcott has written series of short essays of birds found in the Upper Midwest and assembled them in an easy-to-read book. As an ornithologist and avid birder in this region, I'll admit that I didn't know what to expect when I opened the cover-would the focus be on rarities, would there be an identification component, are there tips for finding each species, and at what audience was the book aimed? Ultimately, I …

Atamasco Lily, Zephyranthes Atamasca, W. John Hayden

Biology Faculty Publications

Simple and pure, Atamasco lilies were among the first of many beautiful wildflowers to be noticed by the Jamestown colonists as they explored the tidewater region of southeastern Virginia. A perennial herb that grows from a subterranean bulb, the leaves are glossy green, linear, flat to somewhat concave, up to one half inch wide and approximately one foot in length. The species name, atamasca, is attributed to Tapehanek words meaning under grass, in reference to the location of the bulb under grass-like leaves. Overall the plant is rather grass-like. Flowers are erect to slightly inclined. As in many lilies, …

The Development Of A Gc/Ms Protocol For The Analysis Of Polysaccharides In Echinacea Purpurea, Michaela Knapp

Undergraduate Theses and Capstone Projects

Echinacea purpurea is an herbal supplement used to reduce symptoms of common colds and flu-like illnesses. As of right now, it is not well understood what chemical components in the plant are immunologically active. The four main potentially immunologically active chemical components in E. purpurea are caffeic acid derivatives, alkamides, polyacetylenes, and polysaccharides. In this investigation, a protocol was developed in an attempt to identify polysaccharides present in Puritan’s Pride E. purpurea (aerial) “non-irradiated” herbal supplement First, an estimate of the crude total polysaccharide content in Puritan’s Pride and in a ChromaDex certified botanical standard (E. purpurea -powdered root) was …

Zephyr Lilies: Simple Beauty Belies Complex Biology, W. John Hayden

Biology Faculty Publications

It is often thus, the best in art appears effortless; the most compelling science, once understood, seems obvious. But talk at length with any artist or scientist and you will learn that what appears simple is actually the culmination of a great deal of work. Zephyr, or Jamestown, lilies are like that, too. These seemingly simple flowers are merely the elegant end product of some very complex underlying biology, the details of which are imperfectly understood.

Vegetative Characteristics Of Pronghorn Bed Sites In Wind Cave National Park, South Dakota, Christopher N. Jacques, Jonathan A. Jenks, Jaret D. Sievers, Daniel E. Roddy

The Prairie Naturalist

Much of the previous literature on pronghorn (Antilocapra americana) fawns has focused on fawn mortality (Beale 1978, Barrett 1984, Gregg et al. 2001) and social behavior (Kitchen 1974, Autenrieth and Fichter 1975, Bromley 1977). Selection of bed sites by pronghorn fawns is a major factor affecting fawn survival (Bromley 1978, Barrett 1981, O'Gara et al. 1986, VanSchmus 1990) because adequate cover is a crucial component of fawn bed site selection (Autenrieth 1984). Alldredge et al. (1991) reported that fawns selected dense shrub cover but avoided the most-dense cover in sagebrush-steppe communities in southcentral Wyoming while Tucker and Gamer …

Intraspecific And Interspecific Territoriality In Microtus Ochrogaster And M. Pennsylvanicus, David J. Tazik, Lowell L. Getz

The Prairie Naturalist

Adult female Microtus ochrogaster and M. pennsylvanicus displayed interspecific territorial behavior in a bluegrass site in Illinois. We concluded that within a site, interspecific territorial behavior might be a factor in non-synchronous population fluctuations characteristic of the two species.

Woodland Bird Use Of In-Channel Islands In The Central Platte River, Nebraska, William C. Scharf

The Prairie Naturalist

Recapture data showed woodland obligate birds from riparian habitats made substantial use of thinly vegetated, adjacent small islands in the Platte River. During the bird nesting and spring migration seasons of 200 I through 2004, there were 4,360 individuals of 90 species captured on both mainland and in: hannel island sites. Island locafion captures totaled 595 individuals of 47 species )etween 2002 and 2004. Islands formerly were considered inconsequential for coraging and nesting of passerines. My study substantiated passerine use of Islands and provided a rationale for additional consideration of islands for migration and nesting management. Assemblages of bird species …

Mallard Brood Movements In The Canadian Prairie Parklands, Garnet H. Raven, Todd W. Arnold, David W. Howerter, Llwellyn M. Armstrong

The Prairie Naturalist

We radiotracked 308 mallard (Anas platyrhynchos) broods from hatching until 30 days of age Oij 15 study areas located throughout the Canadian Prairie Parklands to examine patterns of variation in movement frequency and distance. Broods moved an average of 350 m from nests to first wetlands (SO = 390), with 94% of broods moving less than I km. After leaving the nest, broods had a 23% probability of moving to a new wetland each day, but movement probability was a complex function of study area, hatch date, and ducking age, with younger and earlier-hatched broods exhibiting greater movement …

Partial Characterization Of Two Moderately Halophilic Bacteria From A Kansas Salt Marsh, Aileen M. Johnson, Lance R. Thurlow, Sam R. Zwenger, Eric T. Gillock

The Prairie Naturalist

Two bacterial species were isolated from a salt marsh located on privately owned land in Russell County, Kansas. Water samples from the saIt marsh were streaked for isolation on tryptic soy agar supplemented with 12 % NaCI. Visual scanning of the plates revealed two prominent colony types. The two colony types were subcultured repeatedly until axenic cultures were obtained. 80th of these organisms were shown to be moderately halophilic. The organisms were characterized partially by fatty acid methyl ester analysis, 16S rRNA sequencing, and scanning electron microscopy. These studies revealed that the bacteria previously were unreported members of genera Marinococcus …

Ips Pini (Curculionidae: Scolytinae) Is A Vector Of The Fungal Pathogen, Sphaeropsis Sapinea (Coelomycetes), To Austrian Pines, Pinus Nigra (Pinaceae), Justin G.A. Whitehall, Jeffery S. Lehman, Pierluigi Bonello

Biology and Earth Science Faculty Scholarship

Sphaeropsis sapinea (Fr.:Fr.) Dyko and Sutton, is among the most common and widely distributed pathogens of conifers worldwide. S. sapinea is disseminated over short distances by rain splash and moist wind, but significant knowledge gaps regarding long-range dispersal remain. Our objective was to determine whether or not the pine engraver beetle, Ips pini Say, is a vector of the pathogen onto Austrian pines (Pinus nigra Arnold). In 2004 and 2005, individuals of I. pini were collected with pheromone traps at two locations in central Ohio (197 and 1,017 individuals for 2004 and 2005, respectively) and screened for the presence of …

Water In Beaver Dam Wash And Lytle Preserve, Stanley L. Welsh

Books by Faculty of the Monte L. Bean Life Science Museum

This short work is derived from a manuscript prepared for presentation in a water adjudication hearing, following a proposal to pipe water from wells in Beaver Dam Wash for transfer across state lines to be used for culinary and other purposes in Mesquite, Nevada. The Wash is estimated to yield 2000 acre feet of water annually, mostly as subsurface flow, at the Arizona line. About a third of that amount is already appropriated by users along the Wash in Utah, but there are applications pending for more than 100,000 acre feet in Utah. Thus, the Wash is already oversubscribed by …

Conservation Of B Class Gene Expression In The Second Whorl Of A Basal Grass And Outgroups Links The Origin Of Lodicules And Petals, Clinton Whipple, Michael Zanis, Elizabeth Kellogg, Robert Schmidt

Biology Department Faculty Works

Studies of flower development in core eudicot species have established a central role for B class MADS-box genes in specifying petal and stamen identities. Similarly in maize and rice, B class genes are essential for lodicule and stamen specification, suggesting homology of petals and lodicules and conservation of B class gene activity across angiosperms. However, lodicules are grass-specific organs with a morphology distinct from petals, thus their true homology to eudicot and nongrass monocot floral organs has been a topic of debate. To understand the relationship of lodicules to the sterile floral organs of nongrass monocots we have isolated and …

In Silico Analysis Of Terpene Synthase Genes In Arabidopsis Thaliana, Sam Zwenger, Chhandak Basu

Biological Sciences Faculty Publications

Terpenes are defense chemicals found in wide groups of plants. Terpenoids play a large role in plant development and stress response. The terpene synthase family comprises a diverse set of genes, all which contribute to production of terpenoids. We have used tools of bioinformatics and performed an in silico analysis of developmental and tissue specific terpene synthase gene expression in Arabidopsis thaliana, as well as those expressed due to biotic and abiotic environmental stimuli. Using software tools from Genevestigator, a powerful microarray analyzer, we used multiple tool sets to better understand terpene synthase expression in Arabidopsis, which will hopefully open …

Performance Of Dionaea Muscipula As Influenced By Developing Vegetation, James O. Luken

Biology

Demography, growth, and flowering of Dionaea muscipula (Venus' fly trap) were studied during three years (2003–2005) following prescribed fire. Data were collected in permanent quadrats where the developing vegetation was either repeatedly clipped or allowed to grow. Clipping increased light availability at the soil surface. Over the study period, seedling establishment and flowering declined with increasing time since the last prescribed burn. Seedling densities did not differ between clipped and control quadrats, although greater numbers of seedlings grew to adult size in control quadrats and this significantly influenced population size-class structure. Clipping had no effect on leaf number or senescence, …

Additions To The Flora Of Connecticut, Gordon C. Tucker

Faculty Research & Creative Activity

Since the publication of the Connecticut checklist by Dowhan (1979), new state records have continued to appear. These were summarized by Mehrhoff (1995), including some made by Tucker ( 1987, 1991 ). Although geographically distant, the flora of Connecticut has continued to hold my attention since the publication of a flora of the southeastern part of the state (Tucker 1995). Over the past decade, I have made several collections that are new records for the state flora. These new records are reported in this paper, as well as a 1970 collection of Coronilla scorpio ides that was never added to …
