Faculty Publications from the Harold W. Manter Laboratory of Parasitology

Parasites are agents of disease in humans, livestock, crops, and wildlife and are powerful representations of the ecological and historical context of the diseases they cause. Recognizing a nexus of professional opportunities and global public need, we gathered at the Cedar Point Biological Station of the University of Nebraska in September 2012 to formulate a cooperative and broad platform for providing essential information about the evolution, ecology, and epidemiology of parasites across host groups, parasite groups, geographical regions, and ecosystem types. A general protocol, documentation–assessment–monitoring–action (DAMA), suggests an integrated proposal to build a proactive capacity to understand ...


Studies On The Ecology Of The Endangered Camaenid Land Snail Thersites Mitchellae (Cox, 1864), Jonathan Leslie Parkyn Jan 2014

Studies On The Ecology Of The Endangered Camaenid Land Snail Thersites Mitchellae (Cox, 1864), Jonathan Leslie Parkyn

Theses

Many Australian land snail species are assumed to have declined in distribution and abundance, but there are few quantitative data available to assess their conservation status. Thersites mitchellae (Cox, 1864) (Camaenidae) is listed as endangered (category ENC2a) on the IUCN 1997 Red List of Threatened Species. Population parameters such as abundance, probability of survival, and probability of site occupancy were estimated. The methods take detection probability into account and allow for the inclusion of sampling, habitat, and individual animal covariates. These models and techniques offer considerable scope for application to land snail conservation particularly for species at risk of extinction.

Enhancing Coastal Resilience: Perspectives On Valuing Ri Coastal Lands, Kyle Nyskohus Apr 2013

Enhancing Coastal Resilience: Perspectives On Valuing Ri Coastal Lands, Kyle Nyskohus

Honors Projects in Science and Technology

This paper discusses coastal resilience as an organizing framework for future policymaking, coastal planning, and insurance decisions, and explores the different perspectives of the value of ecosystems held by various stakeholders in Rhode Island’s coastal communities. A grounded theory approach was used in an effort to abstract general insights from the substantive but isolated areas of coastal management and economics. Special attention is given to the perspectives of municipal decision makers, the National Flood Insurance Program, natural economists, and real estate developers. We have (1) conducted a statistical analysis of environmental spending of RI towns, (2) identified key models ...


A Reexamination Of The Eastern Collared Lizard (Crotaphytus Collaris Collaris) In Arkansas, Ashley A. Grimsley Aug 2012

A Reexamination Of The Eastern Collared Lizard (Crotaphytus Collaris Collaris) In Arkansas, Ashley A. Grimsley

Theses and Dissertations

Loss of suitable habitat is a threat to species worldwide. Habitat destruction, including loss, change, and fragmentation of habitat, is the leading cause of species extinction. Eastern collared lizards (Crotaphytus collaris collaris) are habitat specialists on glades. Both C. c. collaris and glade habitats are rare and of special concern in the state of Arkansas. Many glade populations have already been extirpated in the Ozarks of Arkansas and Missouri. Increasing knowledge of the distribution, habitat structure, and population dynamics of C. c. collaris is important to ensure the survival of this species in Arkansas.

A literature review of the C ...


Investigating Three Decades Of Vegetation Change In A Mojave Desert Mountain Range, Chris Lee Roberts May 2012

Investigating Three Decades Of Vegetation Change In A Mojave Desert Mountain Range, Chris Lee Roberts

UNLV Theses, Dissertations, Professional Papers, and Capstones

This project is a vegetation change study spanning 29 years in the Newberry Mountains of Southern Nevada. Long term monitoring data are crucial for understanding the effects of climate change on vegetation dynamics. Successful management intervention in vegetation change will require identification of early indicator plant species and their responses to climatic cues. This project is one of the oldest comparisons of resurveyed Mojave vegetation community plots with repeatable methodology and the longest survey interval reported for the southeastern Mojave Desert. 103 plots were relocated and resurveyed based on data methods in Jim Holland's thesis titled "A Vegetative Analysis ...

Ecology And Behaviour Of The Black-Billed Capercaillie (Tetrao Urogalloides Stegmanni) In The Khentej Mountains, Mongolia, Siegfried Klaus, Karl-Heniz Schindlatz, Alexander V. Andreev, Hans-Heiner Bergmann Jan 2012

Ecology And Behaviour Of The Black-Billed Capercaillie (Tetrao Urogalloides Stegmanni) In The Khentej Mountains, Mongolia, Siegfried Klaus, Karl-Heniz Schindlatz, Alexander V. Andreev, Hans-Heiner Bergmann

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Introduction

A common inhabitant of East Siberian larch forests, the Siberian or black-billed capercaillie (Tetrao urogalloides) ranges south to the limits of the boreal forests in the northern Mongolian mountains and east to the very coast of the Asian continent (KLAUS et al. 1989). Tetrao urogalloides MIDDENDORF (1851) has priority over T. parvirostris BONAPARTE (1856). Therefore, we prefer the T. urogalloides.

The subspecies T.u. stegmanni was first described on the basis of morphological differences by POTAPOV (1985) using specimens collected during Russian expeditions by KOZLOVA (1930). This description was based on 18 males in the collection at the Zoological ...

Biogeochemical Couplings Among Earth’S Ecosystems: A Focus On Old-Growth Tropical Rainforest, Philip Graham Taylor Jan 2012

Biogeochemical Couplings Among Earth’S Ecosystems: A Focus On Old-Growth Tropical Rainforest, Philip Graham Taylor

Ecology & Evolutionary Biology Graduate Theses & Dissertations

This dissertation explores how physical and biological processes organize the interaction of carbon and nutrient cycles, which underpin life on Earth. In Chapter 2, I establish that ecosystem nitrate accrual exhibits consistent and negative nonlinear correlations with organic carbon availability along a hydrologic continuum from soils, through fresh- water systems and coastal margins, to the open ocean. Across this diversity of environments, we find evidence that resource stoichiometry strongly influences nitrate accumulation by regulating a suite of microbial processes that couple dissolved organic carbon and nitrate cycling.

In Chapter 3, I address the climate sensitivity of carbon cycling in old-growth ...


The Management Of Feral Pig Socio-Ecological Systems In Far North Queensland, Australia, Gabriela Shuster Jan 2012

The Management Of Feral Pig Socio-Ecological Systems In Far North Queensland, Australia, Gabriela Shuster

Dissertations & Theses

The development of management programs for socio-ecological systems that include multiple stakeholders is a complex process and requires careful evaluation and planning. This is particularly a challenge in the presence of intractable conflict. The feral pig (Sus scrofa) in Australia is part of one such socio-ecological system. There is a large and heterogeneous group of stakeholders interested in pig management. Pigs have diverse effects on wildlife and plant ecology, economic, health, and social sectors. This study used the feral pig management system as a vehicle to examine intractable conflict in socio-ecological systems. The purpose of the study was to evaluate ...


Sharing A Vision For Biodiversity Conservation And Agriculture, John E. Quinn Jan 2012

Sharing A Vision For Biodiversity Conservation And Agriculture, John E. Quinn

Papers in Natural Resources

Conservation biology and agriculture share a common landscape and a future that demands novel research and practice. Inevitably, limited resources create conflict in the absence of a shared vision forward. Therefore, given the similarities in proximate and even ultimate goals, we must envision a joint path toward renewable and resilient agroecosystems. In this commentary, I highlight the root of past conflicts and share a vision of progress forward that encompasses mutually beneficial outcomes. I include six areas of anticipatory research and inquiry at the intersection of conservation biology and agriculture to better identify shared goals and facilitate more frequent communication ...


Climate And Vegetation Change In The Newberry Mountains, Southern Clark County, Nevada, Ross Joseph Guida Aug 2011

Climate And Vegetation Change In The Newberry Mountains, Southern Clark County, Nevada, Ross Joseph Guida

UNLV Theses, Dissertations, Professional Papers, and Capstones

Ecological studies have shown worldwide that vegetation is being affected by climate change. Species are shifting to new elevations and physiographic positions to adapt to changes in their environment. More specifically, paleoecology studies in the Mojave Desert have shown shifting vegetation patterns in response to past warming and precipitation changes. Recent studies have shown mortality among desert plants related to extended drought and warming. However, few studies have shown how the geographic distribution of Mojave Desert species has changed during this most recent period of warming. This study addresses this gap in the literature by focusing on several plant species ...


The Distribution And Life Cycle Of Alliaria Petiolata In Lincoln, Nebraska, Caleb Pharris Jul 2011

The Distribution And Life Cycle Of Alliaria Petiolata In Lincoln, Nebraska, Caleb Pharris

Environmental Studies Undergraduate Student Theses

Alliaria petiolata (Garlic Mustard) is a biennial alien invasive plant species of the Brassicacea family. It is responsible for displacing native plant species throughout North America and its management has proven to be extremely difficult. Recently several populations of Alliaria petiolata have been discovered in southwestern Lincoln, Nebraska. The spread of Alliaria petiolata is a concern for natural resource managers and the general public. Due to the difficulty of its control, Alliaria petiolata is capable of creating monocultures which diminish the aesthetic value of an ecosystem. While most commonly found in the understory of hardwood forests, it is capable of ...


Old Father Hudson: The Three Stages Of Environmental Activism In The Hudson River Valley, Gregory P. Cannillo Jun 2011

Old Father Hudson: The Three Stages Of Environmental Activism In The Hudson River Valley, Gregory P. Cannillo

Honors Theses

Consequences of development have threatened the health of the Hudson River for decades. These have included the prospect of destroying scenic value of the Hudson River Valley with the a hydroelectric power plant on Storm King Mountain, as well as the pollution of the river itself by a variety of industrial sources. Since the 1960s, a long lineage of environmental activism in the Hudson River Valley has emerged to address those issues. The example of the Hudson River supplies an excellent case study of how environmental issues began to be addressed in the later half of the 20th century. I ...

Development And Testing Of An Unmanned Aircraft System For Environmental Science, Jerald James Brady Jan 2011

Development And Testing Of An Unmanned Aircraft System For Environmental Science, Jerald James Brady

Open Access Theses & Dissertations

For some environmental science applications, Unmanned Aircraft Systems (UASs) are increasingly recognized for their capacity to collect remotely sensed data in a safer, more efficient and effective manner than is permitted with manned aircraft and satellite remote sensing platforms. To date, however, technological, human, and other challenges have constrained adoption of UASs in the environmental sciences. This study developed and tested a new UAS for an archetypical environmental science research group (stakeholder) composed of non-UAS experts. Specifically, this thesis: 1) Assessed the research and operational needs of the stakeholder to determine the optimum UAS platform; 2) Developed an Unmanned Aerial ...


Seasonal Variation In Terrestrial Insect Subsidies To Tropical Streams And Implications For The Diet Of Rivulus Hartii, David C. Owens May 2010

Seasonal Variation In Terrestrial Insect Subsidies To Tropical Streams And Implications For The Diet Of Rivulus Hartii, David C. Owens

Dissertations & Theses in Natural Resources

Terrestrial invertebrates subsidize fish diets in lotic ecosystems. Seasonality strongly influences terrestrial invertebrate abundance in temperate regions and alters their delivery to streams. Seasonal changes in the tropics are characterized by distinct wet and dry periods, with marked variation in invertebrate abundance. However, little is known about how these seasonal changes affect invertebrate subsidies and their ecological consequences for tropical streams. We measured the effect of rainfall and canopy density on terrestrial invertebrate falling input, as well as seasonal variation in falling input, benthic and drifting invertebrate, and Rivulus hartii (Hart’s Rivulus) diet composition during both the wet and ...

The Natural History, Conservation Status And Ecology Of The Eastern Pygmy-Possum (Cercartetus Nanus), Jamie Mark Harris Jan 2010

The Natural History, Conservation Status And Ecology Of The Eastern Pygmy-Possum (Cercartetus Nanus), Jamie Mark Harris

Theses

Many populations of Australian wildlife appear to be diminishing as human activities rapidly encroach on natural areas. Modern conservation efforts seek to provide management solutions, focussing particularly on those species that are officially classed as threatened. However, knowledge of the true status of most species is glaringly incomplete, with fundamental information about distribution and abundance yet to be properly assembled. Hence, there is an increasing need for applied research, particularly on the under-studied species, to assist efforts to conserve wildlife. The eastern pygmy-possum (Cercartetus nanus) provides a good example of a species that requires further study, particularly because it is ...


Differential Response Of Amp Activated Protein Kinase (Ampk) And Hsp70 To Temperature Stress In The Gastropod, Nucella Lapillus, Emily Zimmermann Apr 2009

Differential Response Of Amp Activated Protein Kinase (Ampk) And Hsp70 To Temperature Stress In The Gastropod, Nucella Lapillus, Emily Zimmermann

All Theses And Dissertations

Populations of the gastropod Nucella lapillus are polymorphic for shell color, with light-colored shells predominating on warmer, wave-protected shores and dark-colored shells limited primarily to cooler, wave-exposed shores. During thermal stress, darker shells attain higher body temperatures than lighter shells. These results suggest that heat stress may determine field distribution patterns. However, there is currently little evidence of physiological consequences of thermal stress in these organisms. Following the guiding hypothesis that heat stress leads to cellular energy depletion, we explored whether the central energy regulator AMP-activated Protein Kinase (AMPK) is activated by heat stress. We compared this response in both ...


Conservation Implications Of A Marbled Salamander, Ambystoma Opacum, Metapopulation Model, Ethan B. Plunkett Jan 2009

Conservation Implications Of A Marbled Salamander, Ambystoma Opacum, Metapopulation Model, Ethan B. Plunkett

Masters Theses 1911 - February 2014

Amphibians are in decline globally and a significantly greater percentage of ambystomatid salamander species are in decline relative to other species; habitat loss contributes significantly to this decline. The goals of this thesis is to better understand extinction risk in a marbled salamander (ambystoma opacum) population and how forestry effects extinction risk. To achieve this goal we first estimated an important life history parameter (Chapter 1) then used a metapopulation model to estimate population viability and determine what aspects of their life history put them most at risk (Chapter 2) and finally predicted extinction risk in response to hypothetical forestry ...

Terrestrial Arthropod Community And Indicators Of Biotic Integrity For Iowa Tallgrass Prairie, Jessica Marie Orlofske Jan 2008

Terrestrial Arthropod Community And Indicators Of Biotic Integrity For Iowa Tallgrass Prairie, Jessica Marie Orlofske

Retrospective Theses and Dissertations

The tallgrass prairie has become one of the most endangered ecosystems in North America. Thus, there have been attempts to restore and reconstruct native tallgrass prairie. Arthropods, the most diverse taxonomic group on the prairie, have not received adequate attention. A comprehensive arthropod survey in Iowa prairies has not been attempted since the 1930's, and therefore lacks information regarding recent prairie restoration efforts. Arthropods can also provide valuable information related to ecosystem function or biotic integrity when used as bioindicators. However, effective, reliable arthropod bioindicators have not been clearly identified. A survey of arthropods using sweep net transects was ...

Importance Of Early Successional Forest For Wildlife In Southern New England, Amy Wynia May 2007

Importance Of Early Successional Forest For Wildlife In Southern New England, Amy Wynia

Senior Honors Projects

Many bird species that require early successional forest are declining in the Northeast U.S. because such habitat is relatively rare and when they inhabit the more common mature forests or suburban areas they are less successful. Early successional forest is maintained by regular disturbance (wind, fire, clear-cutting, and flooding) which has been happening less frequently during the past 50 years. Bird species that have declined during this time and which inhabit early successional forest include ruffed grouse (Bonasa umbellus), blue jay (Cyanocitta cristata), chestnut-sided warbler (Dendroica pensylvanica), gray catbird (Dumetella carolinensis), field sparrow (Spizella pusilla), golden-winged warbler (Vermivora chrysoptera ...
