Gray Fox And Coyote Abundance And Diet Responses After A Wildfire In Central Arizona, Stan C. Cunningham, Laribeth Kirkendall, Warren Ballard May 2006

Gray Fox And Coyote Abundance And Diet Responses After A Wildfire In Central Arizona, Stan C. Cunningham, Laribeth Kirkendall, Warren Ballard

Western North American Naturalist

There is a paucity of information on the effects of wildfire on carnivores. We studied the effects of a 237-km2 catastrophic wildfire in the Mazatzal Mountains, Arizona, on gray foxes (Urocyon cinereoargenteus) and coyotes (Canis latrans). We indexed relative abundance 3 times each year from 1996 to 1998 using scat transects in burned and unburned areas. We collected scats to estimate diet and measured small mammal abundance and mast availability in 1997 and 1998. We also measured vegetation cover in burned and unburned sites. Gray fox indices declined 3 months postfire, but after 30 months, …

Plant Species Richness At Different Scales In Native And Exotic Grasslands In Southeastern Arizona, Steven P. Mclaughlin, Janice E. Bowers May 2006

Plant Species Richness At Different Scales In Native And Exotic Grasslands In Southeastern Arizona, Steven P. Mclaughlin, Janice E. Bowers

Western North American Naturalist

Species richness in Madrean mixed-grass prairies dominated by native or exotic species in southeastern Arizona was characterized at the community and point scales using ten 1-m2 quadrats nested within each of eight 1000-m2 plots. In the 1000-m2 plots average richness was significantly higher in oak savanna (OS, 121.0 species) than in exotic grassland on mesa tops (EMT, 52.0 species), whereas native grassland on mesa slopes (NMS, 92.5 species) and native grassland on mesa tops (NMT, 77.0 species) did not differ significantly in richness from OS or EMT. When richness was partitioned by life form, EMT was notably …

The Effect Of Livestock Grazing On The Rainbow Grasshopper: Population Differences And Ecological Correlates, Sandra J. Debano May 2006

The Effect Of Livestock Grazing On The Rainbow Grasshopper: Population Differences And Ecological Correlates, Sandra J. Debano

Western North American Naturalist

This study examined the effect of livestock grazing on a common herbivore in semiarid grasslands of the Southwest: the rainbow grasshopper, Dactylotum variegatum. Population attributes and key environmental variables were compared between sites on active cattle ranches and sites on a 3160-ha ungrazed sanctuary. Although density of D. variegatum nymphs did not differ significantly between grazed and ungrazed sites, adult density was significantly lower on grazed sites, and sex ratios differed between grazed and ungrazed sites over time. Grazed sites had higher percentages of bare ground and fewer Baccharis pteronioides, a common shrub. However, only bare ground was …

Growth Rate And Thermal Tolerance Of Two Endangered Snake River Snails, Steven Lysne, Peter Koetsier May 2006

Growth Rate And Thermal Tolerance Of Two Endangered Snake River Snails, Steven Lysne, Peter Koetsier

Western North American Naturalist

We investigated the temperature tolerance and growth of 2 federally protected freshwater gastropods from southern Idaho: Valvata utahensis and Pyrgulopsis idahoensis. Snails were collected in the Snake River and transported to the laboratory where they were kept under highly controlled conditions. In varying-temperature, short-duration experiments, the temperatures tolerated by both species were between 7°C and 34°C. In constant-temperature, long-duration experiments, growth rates were between 0.004 mm · d−1 and 0.016 mm · d−1, and we created growth curves for both species that were previously lacking. Our results are among the first to report temperature tolerances and …

Successful Nesting By A Bald Eagle Pair In Prairie Grasslands Of The Texas Panhandle, Clint W. Boal, Matthew D. Giovanni, Blake N. Beall May 2006

Successful Nesting By A Bald Eagle Pair In Prairie Grasslands Of The Texas Panhandle, Clint W. Boal, Matthew D. Giovanni, Blake N. Beall

Western North American Naturalist

We observed a breeding Bald Eagle (Haliaeetus leucocephalus) pair nesting in a short-grass prairie and agricultural community on the southern Great Plains of the Texas Panhandle in 2004 and 2005. The nesting eagles produced 1 fledgling in 2004 and 2 fledglings in 2005. Our assessment of landcover types within a 5-km radius of the nest indicated that grasslands accounted for most of the area (90%), followed by agricultural lands (8%). Black-tailed prairie dog (Cynomys ludovicianus) colonies occupied 2.5% of the area, and single human residences with associated structures (i.e., barns) occupied <1%. The nearest source of permanent surface water >2.5 ha in surface area …

The World Bank And The Ideology Of Reform In International Development Discourse, Joel M. Ngugi May 2006

The World Bank And The Ideology Of Reform In International Development Discourse, Joel M. Ngugi

ExpressO

Does the current development reform agenda, especially the one operationalized by the World Bank, is Ideological? If so, does it matter? These are the two questions that animate this article. In answering both questions in the affirmative, the article first demonstrates how the current development reform agenda is Ideological. It then discusses why and how it matters that the development reform agenda is Ideological. First, the article argues that Ideological rendering of the development reform agenda effectively weakens the ability of Third World countries to articulate their economic and foreign policies in ways that would benefit their citizenry the most. …

A Qualitative Approach To Understanding The Everyday Difference Between Acquaintanceship And Friendship: How Western Organizational Members Discriminate These Concepts Through Communicative Interaction, Bobby A. Hines May 2006

A Qualitative Approach To Understanding The Everyday Difference Between Acquaintanceship And Friendship: How Western Organizational Members Discriminate These Concepts Through Communicative Interaction, Bobby A. Hines

Communication

Stewart & Bennett posited the term 'friend, ' used by members of U.S. American culture, 'may refer to anyone from a passing acquaintance to a lifetime intimate' (p. 100-101). Although American use of the term illustrates broad applicability as acceptable, Americans describe the label as having different meanings depending on those to whom they apply it. This qualitative research study utilizes narrative inquiry to gain a better understanding of the everyday lived experience of U.S. American organizational members' friendships and acquaintanceships within the organizational setting and how they perceive the way they discern between friends and acquaintances inside an organization …

"Let Us Die Trying": A Post-Colonial Reading Of Velma Wallis, Seth G. Myers May 2006

"Let Us Die Trying": A Post-Colonial Reading Of Velma Wallis, Seth G. Myers

English

This essay explores the work of Velma Wallis from the perspective of post-colonial theory. Her works, Two Old Women and Bird Girl and the Man who Followed the Sun are read within this theoretical framework as volatile and resistant texts, in opposition to readings that might limit their meaning as ethnographic or otherwise. I outline the generalities of my theoretical framework with reference to Edward Said and Homi K. Bhabha, before I approach a discussion of Native American literature and Velma Wallis specifically. Within this theoretical framework, I find that Wallis resists, not only generic definition, but the larger structures …

What, If Any, Are The Ethical Obligations Of The U.S. Patent Office? A Closer Look At The Biological Sampling Of Indigenous Groups, Marina L. Whelan May 2006

What, If Any, Are The Ethical Obligations Of The U.S. Patent Office? A Closer Look At The Biological Sampling Of Indigenous Groups, Marina L. Whelan

Duke Law & Technology Review

The patenting of biological resources collected from indigenous groups has become a controversial trend. Two U.S. patents in particular, one claiming a cell-line from a 26-year old Guayami woman and one claiming a leukemia virus from a Hagahai man in Papua New Guinea, demonstrate just how volatile this issue has become. This iBrief examines how, in light of such "ethically questionable" patents, the U.S. Patent Office has failed to implement any procedures to identify or curb patent applications involving indigenous peoples.

Snowshoe Hare Densities In Post-Fire Vegetation, Hans Mathias Eriksson May 2006

Snowshoe Hare Densities In Post-Fire Vegetation, Hans Mathias Eriksson

Biological Sciences

The objective of this study was to investigate if patterns of snowshoe hare (Lepus americanus) densities in interior Alaska are influenced by post-fire successional stage. Stages of succession were classified using the proxy Time Since Last Fire (TSLF). I estimated snowshoe hare densities during the summers of 2003 and 2004 in 5 young (10-20 yrs) and 5 old (44-46 yrs) burns, each with an adjacent unburned control, using indirect distance sampling methods. Because indirect distance sampling has not previously been applied for snowshoe hares, I compared these results with a traditional mark-recapture analysis. Hare density estimates from both methods were …

Temporal And Spatial Distribution Of Interior Alaska White-Fronted Geese (Anser Albifrons Frontalis), Deborah Dawn Webb May 2006

Temporal And Spatial Distribution Of Interior Alaska White-Fronted Geese (Anser Albifrons Frontalis), Deborah Dawn Webb

Biological Sciences

To address the question if white-fronted geese molting in Interior Alaska could be temporally and spatially delineated from the rest of the mid-continent white-fronted goose population, I (1) determined interannual variation in temporal and spatial distribution of geese from Interior Alaska during fall and winter, (2) contrasted temporal and spatial distribution of Interior Alaska geese with Arctic Slope (Alaska) geese, and (3) contrasted migration timing of Interior Alaska geese with Canadian Arctic geese on fall staging areas in prairie Canada. Migration of Interior Alaska geese occurred synchronously and earlier than migration of Arctic Slope geese between Alaska and fall staging …

An Essential Role For Endocytosis Of Rhodopsin Through Interaction Of Visual Arrestin With The Ap-2 Adaptor, Nicholas R. Orem, Luxi Xia, Patrick J. Dolph May 2006

An Essential Role For Endocytosis Of Rhodopsin Through Interaction Of Visual Arrestin With The Ap-2 Adaptor, Nicholas R. Orem, Luxi Xia, Patrick J. Dolph

Dartmouth Scholarship

Previously, we have identified a class of retinal degeneration mutants in Drosophila in which the normally transient interaction between arrestin2 (Arr2) and rhodopsin is stabilized and the complexes are rapidly internalized into the cell body by receptor-mediated endocytosis. The accumulation of protein complexes in the cytoplasm eventually results in photoreceptor cell death. We now show that the endocytic adapter protein AP-2 is essential for rhodopsin endocytosis through an Arr2-AP-2beta interaction, and mutations in Arr2 that disrupt its interaction with the beta subunit of AP-2 prevent endocytosis-induced retinal degeneration. We further demonstrate that if the interaction between Arr2 and AP-2 is …

Understanding Eating Boundaries: A Study Of Vegetarian Identities, Susan Kremmel May 2006

Understanding Eating Boundaries: A Study Of Vegetarian Identities, Susan Kremmel

USF Tampa Graduate Theses and Dissertations

My research uses participants' understandings to look at how people define and use the identities and categories of "vegetarian" and "meat-eater." My research examines what it means to be vegetarian, how ideals and moral hierarchies are understood, and how issues of identity importance, social support, and boundary work are components of vegetarian identity construction processes. My research highlights the unmarked character of the meat-eating identity and investigates the variations and complexities of eating behaviors and identities. Learning more about how both vegetarians and meat-eaters construct vegetarian identities contributes to our understanding of identities and how, despite ambiguities, people experience identities. …

A Structural Analysis And Assessment Of The Bjorklunden Forest, Andrew Allan Link May 2006

A Structural Analysis And Assessment Of The Bjorklunden Forest, Andrew Allan Link

Lawrence University Honors Projects

A common assumption in ecology is that stability within an ecosystem is reached through equilibrium. In actuality, the mechanisms that help maintain a healthy ecosystem are based upon heterogeneity and scale multiplicity. This study assessed the vegetation organization at Bjorklunden as a function of time and space. Comparisons were made to previous research that demonstrated both similarities and differences in the vegetational components of the forest. Certain areas of the forest that were previously believed to be in a permanent steady-state were proved otherwise. While other areas that were thought to mature and climax, did not. The forest at Bjorklunden …

Humpback Whale (Megaptera Novaeangliae) Entanglement In Fishing Gear In Northern Southeastern Alaska, Janet L. Neilson May 2006

Humpback Whale (Megaptera Novaeangliae) Entanglement In Fishing Gear In Northern Southeastern Alaska, Janet L. Neilson

Marine Biology

The prevalence of non-lethal entanglements of humpback whales (Megaptera novaeangliae) in fishing gear in northern southeastern Alaska (SEAK) was quantified using a scar-based method. The percentage of whales assessed to have been entangled ranged from 52% (minimal estimate) to 71% (conditional estimate) to 78% (maximal estimate). The conditional estimate is recommended because it is based solely on unambiguous scars. Eight percent of the whales in Glacier Bay/Icy Strait acquired new entanglement scars between years, although the sample size was small. Calves were less likely to have entanglement scars than older whales and males may be at higher risk than females. …

Multiple B-Class Ephrins And Eph Receptors Regulate Midline Axon Guidance In The Developing Mouse Forebrain, Shannon Wayne Allen John Mendes May 2006

Multiple B-Class Ephrins And Eph Receptors Regulate Midline Axon Guidance In The Developing Mouse Forebrain, Shannon Wayne Allen John Mendes

Open Access Dissertations

Ephrins and Eph receptors have been implicated in a number of developmental processes including axon growth and guidance. One important guidepost is the central nervous system midline, where ephrins and Eph receptors have been implicated. At the embryonic midline, axons either cross into the contralateral central nervous system (CNS) targeting appropriate partners on the opposite side or remain ipsilateral extending either rostrally or caudally. In these studies, we examine a major forebrain commissure called the corpus callosum (CC). Agenesis of the CC is a rare birth defect that occurs in isolated conditions and in combination with other developmental cerebral abnormalities. …

Changes In Co-Survivorship Of Adult Children And Parents: Ju/'Hoansi Of Botswana In 1968 And 1988, Patricia Draper, Nancy Howell May 2006

Changes In Co-Survivorship Of Adult Children And Parents: Ju/'Hoansi Of Botswana In 1968 And 1988, Patricia Draper, Nancy Howell

Department of Anthropology: Faculty Publications

Our study addresses these issues in a sociological microcosm that makes questions about population aging particularly interesting. The group on whom we report are the Ju|'hoansi (!Kung) of western Ngamiland, part of the Kalahari Desert of Botswana. They constitute a noteworthy case for several reasons. Discussion of modernization and its impact on the lives of elderly in traditional society has focused most often on agricultural and peasant societies, rather than on economically simpler groups such as hunter gatherers1). Ju|'hoansi, though now living in permanent settlements, have a recent past of mobile hunting and gathering. Over the past sixty years, Ju|'hoansi …
