Proceedings Of The Eleventh North American Crane Workshop: Preface And Contents

Proceedings of the North American Crane Workshop

The North American Crane Working Group (NACWG) is an organization of professional biologists, aviculturists, land managers, and other interested individuals dedicated to the conservation of cranes and their habitats in North America. Our group meets approximately every 3 years to exchange new information on research and conservation of sandhill and whooping cranes and occasionally reports from abroad. Our meeting in Wisconsin Dells, Wisconsin, 23-27 September 2008, was no exception. The workshop was ably organized by Tom Hoffman, the scientific program was well-constructed by Jane Austin, and George Archibald and Richard Urbanek helped to bring together a memorable field day in …

Wintering Sandhill Crane Distribution And Habitat Use Patterns At Bosque Del Apache National Wildlife Refuge, New Mexico, Tandi L. Perkins, Leigh H. Fredrickson

Proceedings of the North American Crane Workshop

The single most important factor regulating sandhill crane (Grus canadensis) populations is their ability to carry out annual life cycle events while responding to changing habitat availability and distribution across local, regional, and continental landscapes. Wetland and cropland resource availability and distribution across the landscape have become increasingly unpredictable. Recent changes in farming practices, urbanization, and prevailing drought conditions in New Mexico have transformed and reduced dynamic, heterogeneous landscapes into scattered fragments of the original setting. Concerns are increasing for the cumulative influence of these often irreversible actions in providing the type of resources needed by cranes at …

A Taxonomic Revision Of Orthotrichaceae (Musci) With Contributions To The Biosystematics Of Macromitrium Brid. In Malaysia., Yong Kien Thai

Student Works (2010-2019)

Macromitrium (Orthotrichaceae) is a large genus variously divided into infrageneric groups by different authors, resulting in a complex classification which has not included many Malaysian species. This study reviews the taxonomy of Malaysian taxa and extent of morphological variation in relation to the type group. A molecular phylogenetic study was carried out to determine if Malaysian Macromitrium species represented a homogeneous taxonomic grouping. A cladistic analysis of morphological characteristics was attempted for identifying well-defined groups and their key character states. Molecular studies included Maximum Parsimony and Bayesian Inference analyses of two chloroplast DNA regions (rps4 gene and trnL-trnF interspecific region) …

Adsorption Of Lead (Ii) By A Non-Living Algal Biomass., Mudher A Hussein

Student Works (2010-2019)

Conventional techniques for removing dissolved heavy metals are only practical and cost-effective when applied to high strength wastes with heavy metal ion concentrations greater than 100 ppm. The possibility of using a non-living algal biomass to solve this problem was studied. Lead(II) was used in this study because it has been reported to cause several disorders in human. The non-living algal biomass was obtained from the filamentous green alga Spirogyra neglecta. The effects of initial concentration and contact time, pH, and temperature on the adsorption of lead(II) by the non-living algal biomass were studied. The equilibrium isotherms and kinetics were …

Background

The domestic cat has offered enormous genomic potential in the veterinary description of over 250 hereditary disease models as well as the occurrence of several deadly feline viruses (feline leukemia virus -- FeLV, feline coronavirus -- FECV, feline immunodeficiency virus - FIV) that are homologues to human scourges (cancer, SARS, and AIDS respectively). However, to realize this bio-medical potential, a high density single nucleotide polymorphism (SNP) map is required in order to accomplish disease and phenotype association discovery.

Description

To remedy this, we generated 3,178,297 paired fosmid-end Sanger sequence reads from seven cats, and combined these data with the …

Building The Genomic Base-Layer Of The Oral “Omic” World, Forsyth Metagenomic Support Consortium, Jacques Izard

Department of Food Science and Technology: Faculty Publications

With the shift of molecular technologies directed toward the understanding of greater biological complexity of the oral cavity, a knowledge gap was created by the lack of genomic data from the diverse oral microorganisms. To facilitate and enable the interpretation of metagenomic, transcriptomic, and proteomic data generated or soon to be generated from oral biofilms, we are providing reference genomic information from phylogenetically diverse oral bacterial isolates. This work, initiated by the National Institute of Dental and Craniofacial Research as an isolated effort, is now part of the Human Microbiome Project. The goal of this effort is the public release …

Migration Of Northern Yellowstone Elk: Implications Of Spatial Structuring, P. J. White, Kelly M. Proffitt, L. David Mech, Shaney B. Evans, Julie A. Cunningham, Kenneth L. Hamlin

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Migration can enhance survival and recruitment of mammals by increasing access to higher-quality forage or reducing predation risk, or both. We used telemetry locations collected from 140 adult female elk during 2000– 2003 and 2007–2008 to identify factors influencing the migration of northern Yellowstone elk. Elk wintered in 2 semidistinct herd segments and migrated 10–140 km to at least 12 summer areas in Yellowstone National Park (YNP) and nearby areas of Montana. Spring migrations were delayed after winters with increased snow pack, with earlier migration in years with earlier vegetation green-up. Elk wintering at lower elevations outside YNP migrated an …

The Market For Treaties, Natasha Affolder

All Faculty Publications

Corporations are consumers of treaty law. In this article, I empirically examine three biodiversity treaty regimes - the Convention on Biological Diversity, Ramsar Convention, and World Heritage Convention - to demonstrate that corporations implement or internalize treaty norms in a variety of ways that are not captured by the dominant model of treaty implementation – national implementation. As an exegetical model, I explore how corporations use biodiversity treaties as a source of private environmental standards. I focus on the interactions between mining and oil and gas companies and biodiversity treaties, as revealed through transactional documents, corporate reports, security law filings, …

Butterfly Response To Floral Resources At A Heterogeneous Prairie Biofuel Production Site, Benjamin J. Hoksch, Mark C. Myers

Undergraduate Student Work

In the Midwestern USA, current biofuel production systems rely on high input monoculture crops that do little to support biodiversity or protect soil and water resources. The University of Northern Iowa’s Tallgrass Prairie Center is investigating the feasibility of cultivating and harvesting diverse mixes of native prairie vegetation as a sustainable biofuel. In 2009, we established 48 research plots seeded with one of four treatments: 1) switchgrass monoculture, 2) warm-season grass mix (5 species), 3) biomass mix (16 species of grasses and forbs), or 4) prairie mix (32 species of grasses and forbs). We hypothesized that more diverse plant communities …

New Species In The Genus Monoecocesuts (Cestoda: Anoplocephalidae) From Neotropical Rodents (Caviidae And Sigmodontidae), Terry R. Haverkost, Scott Lyell Gardner

Scott L. Gardner Publications

Anoplocephalid cestodes have a worldwide distribution, but relatively few species are known from South American rodents. By examining the collections of the Harold W. Manter Laboratory of Parasitology and the United States National Parasite Collection, 6 new species of Monoecocestus Beddard, 1914, are described, along with a redescription of Monoecocestus mackiewiczi Schmidt and Martin, 1978, based on the type specimens. The discussion includes commentary about uterine development, an important taxonomic character of the family, the vaginal dilation in immature segments (a character of potential taxonomic importance), and the implication of host usage to the evolutionary history and biogeography of species …

Proportion Of Calves And Adult Muskoxen, Ovibos Moschatus Killed By Gray Wolves, Canis Lupus, In July On Ellesmere Island, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Generally Gray Wolves (Canis lupus L., 1758) tend to focus predation on young-of-the-year ungulates during summer, and I hypothesized that wolves preying on Muskoxen (Ovibos moschatus Zimmerman, 1780) in summer would follow that trend. Over 23 July periods observing wolves on Ellesmere Island, Nunavut, Canada, I found that packs of 2-12 adult wolves killed seven calves, one yearling, and five adult muskoxen at distances of 2.9 to 32 km from their current dens and pups. Given a possible bias against finding calves because of their fewer remains, these results do not necessarily refute the hypothesis, but they do …

Prolonged Intensive Dominance Behavior Between Gray Wolves, Canis Lupus, L. David Mech, H. Dean Cluff

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Dominance is one of the most pervasive and important behaviors among wolves in a pack, yet its significance in free-ranging packs has been little studied. Insights into a behavior can often be gained by examining unusual examples of it. In the High Arctic near Eureka, Nunavut, Canada, we videotaped and described an unusually prolonged and intensive behavioral bout between an adult male Gray Wolf (Canis lupus) and a male member of his pack, thought to be a maturing son.With tail raised, the adult approached a male pack mate about 50 m from us and pinned and straddled this …

How Birds Combat Ectoparasites, Dale H. Clayton, Jennifer A. H. Koop, Christopher W. Harbison, Brett R. Moyer, Sarah E. Bush

Harold W. Manter Laboratory of Parasitology: Library Materials

Birds are plagued by an impressive diversity of ectoparasites, ranging from feather-feeding lice, to feather-degrading bacteria. Many of these ectoparasites have severe negative effects on host fitness. It is therefore not surprising that selection on birds has favored a variety of possible adaptations for dealing with ectoparasites. The functional significance of some of these defenses has been well documented. Others have barely been studied, much less tested rigorously. In this article we review the evidence--or lack thereof--for many of the purported mechanisms birds have for dealing with ectoparasites. We concentrate on features of the plumage and its components, as well …

Systematics Of The Genus Ptychadena Boulenger, 1917 (Anura: Ptychadenidae) From Democratic Republic Of The Congo, Katrina Marie Weber

Open Access Theses & Dissertations

This thesis increases the scope of previous phylogenetic analyses that revealed high levels of genetic differentiation within the anuran genus Ptychadena. Herein, I increase sampling of Central African populations of Ptychadena by over six times to examine their relationships to other African populations and to search for cryptic species. This study represents the most comprehensive molecular phylogeny of Ptychadena to date. A total of three mitochondrial (12S, 16S, and cyt b) and two nuclear (RAG1 and rhodopsin) genes were sequenced for 67 specimens of Ptychadena. Maximum parsimony, maximum likelihood, and Bayesian analyses were conducted. These analyses revealed …

Saving Saba Bank: Policy Implications Of Biodiversity Studies, Paul C. Hoetjes, Kent E. Carpenter

Biological Sciences Faculty Publications

Saba Bank has always been an area of special importance to the neighboring island of Saba in the Netherlands Antilles. Sabans traditionally fished on the Bank as far back as 1907, but increasing foreign fishing pressures on the Bank in the 1970s and 1980s forced many Saban fishermen out. Concerns were compounded by the suspicion that shipping was also damaging the benthic habitat of the bank. Fishery legislation, enacted in 1996, brought an end to unlicensed fishing and established Coast Guard enforcement on the Bank, but also led to protests from neighboring countries that previously fished on the Bank.Research was …

Biodiversity Assessment Of The Fishes Of Saba Bank Atoll, Netherlands Antilles, Jeffrey T. Williams, Kent E. Carpenter, James L. Van Tassell, Paul Hoetjes, Wes Toller, Peter Etnoyer, Michael Smith

Biological Sciences Faculty Publications

Biodiversity surveys were conducted on Saba Bank, Netherlands Antilles, to assess ichthyofaunal richness and to compare with published surveys of other Caribbean localities. The primary objective was to estimate the total species richness of the Saba Bank ichthyofauna. A variety of sampling techniques was utilized to survey the fish species of both the visually accessible megafauna and the camouflaged and small-sized species comprising the cryptic ichthyofauna. Based on results presented herein, the number of species known on Saba Bank is increased from 42 previously known species to 270 species. Expected species-accumulation curves demonstrate that the current estimate of species richness …

Increased Weed Diversity, Density And Above-Ground Biomass In Long-Term Organic Crop Rotations, Samuel E. Wortman, John L. Lindquist, Milton J. Haar, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

While weed management is consistently a top priority among farmers, there is also growing concern for the conservation of biodiversity. Maintaining diverse weed communities below bioeconomic thresholds may provide ecosystem services for the crop and the surrounding ecosystem. This study was conducted to determine if weed diversity, density and biomass differ within and among organic and conventional crop rotations. In 2007 and 2008, we sampled weed communities in four long-term crop rotations near Mead, Nebraska, United States using seedbank analyses (elutriation and greenhouse emergence) and above-ground biomass sampling. Two conventional crop rotations consisted of a corn (Zea mays) …
