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 …

The Paper Trail: Paper Use And Disposal At The University Of Rhode Island, Katherine Modzelewski

Senior Honors Projects

The University of Rhode Island has a well-established recycling program, however, the university community does not make full and proper use of the services and facilities provided. This project will specifically look at the use and disposal of paper products that are used for business and educational purposes at the University of Rhode Island and the effects these practices have both up- and down-stream. This analysis will be accomplished by examining the source and disposal of these university-used paper products through interviews with knowledgeable individuals, including those with oversight on the ordering, management, and disposal of professional paper products, a …

School of Natural Resources: Faculty Publications

This paper examines long-term eddy covariance data from 18 European and 17 North American and Asian forest, wetland, tundra, grassland, and cropland sites under nonwater- stressed conditions with an empirical rectangular hyperbolic light response model and a single layer two light-class carboxylase-based model. Relationships according to ecosystem functional type are demonstrated between empirical and physiological parameters, suggesting linkages between easily estimated parameters and those with greater potential for process interpretation. Relatively sparse documentation of leaf area index dynamics at flux tower sites is found to be a major difficulty in model inversion and flux interpretation. Therefore, a simplification of the …

Muir Center Newsletters (1981-2015)

The John Muir University of the Pacific, Stocktoi, CA BER2/3 Sprint; Summer 2< John Muir's World Tour (part V) Lex Chalmers, University of Waikato, Hamilton, New Zealand Preface by W. R. Swagerty, Director, John Muir Center This past spring, I had the good fortune to travel to New Zealand and Australia through sponsorship of the J. William Fulbright Program of the U.S. State Department. At University of Waikato in Hamilton, New Zealand on the North Island, Dean Daniel Zirker introduced me to Professor Lex Chalmers, a distinguished geographer and researcher on his faculty. It turns out that Professor Chalmers had plans to travel to the United States on family business. After learning my interest in following John Muir's trail from his 1904 visit to New Zealand, Lex agreed to help with this project. In May, Chalmers visited us in Stockton and spent time in the John Muir Papers, clarifying the route and obtaining pertinent transcripts and details from the manuscripts. The document that resulted is his excellent work, not mine. I am indebted to Chalmers and the University of Waikato for the time spent helping the world better understand Muir's unpublished travels in New Zealand from the difficult-to-read notebooks that he kept while traveling abroad, and from Linnie Marsh Wolfe's transcriptions from the 1940s or 1950s. We are planning a more extensive academic publication from this preliminary work and share with you the fifth of six segments in the piece that follows. WRS John Muir's remarkable 'World Tour' began on May 29, 1903 with his departure from New York, and ended almost exactly a year later when he arrived back in San Francisco on May 27,1904. For most of this time Muir maintained a detailed daily journal, commenting on the botany, geomorphology and the patterns of human occupance that he encountered. These journals, closely written in pencil and often illustrated, are held in the Holt-Atherton Collection at the University of the Pacific in Stockton, Ca. The collection also holds some of Muir's correspondence written during his travels, and part of the Library collection he established. The journals have attracted scholarly attention, most notably in the transcription work undertaken by Linnie Marsh Wolfe to support her commentaries and 1946 biography of John Muir (Son of the Wilderness: The Life of John Muir). Wolfe's biography, not without its critics, place her at the forefront of commentators on John Muir's contribution to conservation, and her work was recognised by the award of the Pulitzer Prize for biography. Her typescript records of John Muir's journals are an important contribution and they provide the best research source for (Continued on page 6) page 1

Everglades National Park – Surveying The Southernmost Cave In The Continental United States, Lee J. Florea, Amber J. Yuellig

Earth, Environmental, and Atmospheric Sciences Faculty Publications

Everglades National Park encompasses 1.5 million acres of grassland glades, tree islands, cypress strands, and mangrove marshes and is world renowned for natural vistas and wonders at the surface. The cave and karst resources in this park, however, are little known even though much of the park is underlain by limestone. In a recent communication to the authors, Alan Cressler (U.S. Geological Survey, written communication, 2006) described his visit to Palma Vista Cave in Everglades National Park last November that he originally explored and described over 13 years ago (Cressler, 1993).

Extensions Of Local Domains With Trivial Generic Fiber, William Heinzer, Christel Rotthaus, Sylvia Wiegand

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

We consider injective local maps from a local domain R to a local domain S such that the generic fiber of the inclusion map R -> S is trivial, that is P R (0) for every nonzero prime ideal P of S. We present several examples of injective local maps involving power series that have or fail to have this property. For an extension R -> S having this property, we give some results on the dimension of S; in some cases we show dim S = 2 and in some cases dim S = 1.

Ecosystem-Based Fishery Management In South Australia And Victoria, Rebecca Devries

Independent Study Project (ISP) Collection

The detrimental impact from fishing on various species as well as on the overall ecosystem has increased so much over the years that the Australian fishing industry is currently in jeapordy. Scientists, fishery managers, government agencies, industry, and environmental organizations have therefore been actively developing and researching management strategies focused on finding a balance between fisheries and the ecosystem. A new holistic and promising approach, ecosystem-based fishery management, invested in ecological sustainability and the recognition of the critical interdependence between human well-being and ecological health, is currently proposed as the best solution for fishery management.

This paper will consequently investigate …

The Role Of Industrial And Traditional Fishing In Sustainable Resource Management, Aime Schwartz

Independent Study Project (ISP) Collection

For decades, the notion of ‘sustainable development’ has been a source of international contention and debate. While the meanings and implications of sustainable development are widely disputed, it is interpreted by many as an ideal that encompasses social, environmental and economic spheres while promoting the value of human rights in development. Theoretically, this approach allows for the quality of life of current and future generations to be considered in environmental decision-making and formally recognized by national and international standards, dictated primarily by wealthy industrialized governments (Adebowale et al 138). Policy-makers in developing nations continuously face the struggle to balance the …

In order to achieve this aim, and encourage the appreciation and conservation of fish, a number of management strategies have been identified which restrict recreational and commercial fishing. The FHPA is approximately 420 metres long and approximately 130 metres wide at the southern end and 140 metres wide at the northern end.

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

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 …

Fisheries Research Report No.159 - A 12-Month Survey Of Recreational Estuarine Fishing In The South Coast Bioregion Of Western Australia During 2002/03, C.B. Smallwood, N. R. Sumner

Fisheries Research Reports

The Recreational Fisheries Program of the Department of Fisheries, Western Australia, has a strategic plan to conduct comprehensive creel surveys of recreational fishing in each of the state’s marine bioregions (Penn et al., 2003). These bioregions are the West Coast, Gascoyne, Pilbara/ Kimberley and South Coast (Figure 1). To record and monitor changes in recreational catch and fishing effort, an integrated approach where all bioregions are to be surveyed on a regular basis was proposed. Until this study, the South Coast was the only bioregion in which a survey of recreational fishing had not been undertaken. Although originally intended to …

Dental Wash: A Problematic Method For Extracting Microfossils From Teeth (Galley Proofs), Célia H. C. Boyadjian, Sabine Eggers, Karl J. Reinhard

School of Natural Resources: Faculty Publications

A variety of microfossils, originating from plant foods, become trapped in the dental calculus matrix. Processing of dental calculus allows extraction of these microfossils. The resulting data can be used to reconstruct diet at the individual and population levels as the identification of microfossils like starch grains and phytoliths to the generic level, and sometimes to the species level, is possible. However, in some archaeological sites, dental calculus deposits do not preserve well enough to be processed. To prevent the loss of information in such cases, we present a technique, called ‘‘dental wash’’. It permits extracting microfossils from cryptic dental …

Comment On Reinterpreting The Pollen Data From Dos Cabezas, Karl J. Reinhard, Vaughn M. Bryant, Sheila Dorsey Vinton

School of Natural Resources: Faculty Publications

The published pollen analysis of the Dos Cabezas giants, Geyer et al. ([2003]), lists a variety of purported dietary pollen types. The paper also hypothesizes that the giants were poisoned with plant toxins. We have severe reservations about the pollen evidence of diet and poisoning. We suggest that the analysts made several errors in their interpretation. Firstly, some of the discovered pollen types are not prehistoric endemics to the Dos Cabezas region of coastal Peru. These include the pollen of fava beans (cultivated in the Old World), and specified species of agave and sage. We believe that some or all …
