Social Learning For Resolving Community Conflict Over Land-Use Change To Plantation Forestry, Andrea Jane Leys 2010 Southern Cross University

Social Learning For Resolving Community Conflict Over Land-Use Change To Plantation Forestry, Andrea Jane Leys

Theses

This thesis examines social, economic, political and environmental challenges resulting from the conversion of agricultural land to hardwood forestry plantations for a sub-tropical region of Australia, notably the Upper Clarence catchment in north-eastern NSW. The conversion of agricultural land in the catchment to hardwood forestry plantations was an example of land-use change. This change has implications for natural resource management as a whole, as new operational and management practices impact differently on local ecosystems and communities. One of the aims of this study was to quantify these impacts and examine alternative management scenarios for increasing sustainability outcomes at the landscape ...


Analysis Of Eurycea Hybrid Zone In Eastern Missouri, Bonnie Jean Beasley 2010 Missouri University of Science and Technology

Analysis Of Eurycea Hybrid Zone In Eastern Missouri, Bonnie Jean Beasley

Masters Theses

"Evolutionary mechanisms are often difficult to observe in action because evolution generally works slowly over time. Hybrid zones provide a unique opportunity to observe many evolutionary processes, such as reinforcement, because of the rapid changes that tend to occur in these zones. Salamanders provide an ideal model for examining the rapid changes in populations that result from hybridization because many closely-related species lack reproductive barriers. In Missouri, a well-documented hybridization zone exists among the two subspecies Eurycea longicauda longicauda (long-tailed salamander) and E. L. melanopleura (dark-sided salamander). These salamanders inhabit caves, limestone creek beds, and abandoned mine shafts. A closely ...


Zinc Oxide Nanoparticle Disruption Of Store-Operated Calcium Entry In A Muscarinic Receptor Signaling Pathway, Hsiu-Jen Wang 2010 Missouri University of Science and Technology

Zinc Oxide Nanoparticle Disruption Of Store-Operated Calcium Entry In A Muscarinic Receptor Signaling Pathway, Hsiu-Jen Wang

Masters Theses

"The influences of ZnO nanoparticles on cellular responses to activation of muscarinic receptors were studied in Chinese hamster ovary cells expressing the human M3 muscarinic acetylcholine receptor. ZnO particles (20 nm) induced cytotoxicity in a time and concentration-dependent manner: following a 24 h exposure, toxicity was minimal at concentrations below 20 µg/ml but virtually complete at concentrations above 28 µg/ml. ZnO particles did not affect antagonist binding to M3 receptors or allosteric ligand effects, but increased agonist binding affinity while eliminating guanine nucleotide sensitivity. At a noncytotoxic concentration (10 µg/ml), ZnO increased resting [Ca²⁺]i from 40 ...


Laryngeal Apparatus And Call Structure In North American Hylids, Barbara Ann Catherine Fears 2010 Missouri University of Science and Technology

Laryngeal Apparatus And Call Structure In North American Hylids, Barbara Ann Catherine Fears

Masters Theses

"Although the ecological implications and structure of frog calls have been the subject of much study, little is known about the association between the laryngeal apparatus morphology and call structure in North American hylids. In this study linear measurements of the laryngeal apparatus were captured and compared to the call structures of thirteen species of North American hylids. Species examined included: Pseudacris crucifer, P. triseriata, P. ocularis, Acris crepitans blanchardi, Hyla avivoca, H. cinerea, H. gratiosa, H. chrysoscelis, H. versicolor, H. squirella, H. femoralis, H. arenicolor, and H. eximia. Six homologous landmark points were identified, and the lengths between them ...


Ecological And Evolutionary Connectivity Of Reef Corals In Subtropical Eastern Australia : Implications For The Persistence Of High-Latitude Coral Populations, Annika ME Noreen 2010 Southern Cross University

Ecological And Evolutionary Connectivity Of Reef Corals In Subtropical Eastern Australia : Implications For The Persistence Of High-Latitude Coral Populations, Annika Me Noreen

Theses

Coral reefs worldwide are threatened by a variety of pressures, and climate change models predict increasing levels of chronic stress as well as acute disturbances for most reefs. In addition to these global threats, populations on remote reefs are also predicted to be vulnerable due to their isolation from potential source reefs, usually low population size and associated increased extinction risk. Critical for the future of these reefs is dispersal and gene flow between populations (connectivity). This study investigated connectivity, population subdivision, and genetic diversity for three scleractinian reef coral species in discontinuous high-latitude nearshore coral communities and offshore reefs ...

Montane Meadow Change During Drought Varies With Background Hydrologic Regime And Plant Functional Group, Diane M. Debinski, Hadley Alexander Wickham, Kelly Kindscher, Jennet C. Caruthers, Matthew Germino

Ecology, Evolution and Organismal Biology Publications

Climate change models for many ecosystems predict more extreme climatic events in the future, including exacerbated drought conditions. Here we assess the effects of drought by quantifying temporal variation in community composition of a complex montane meadow landscape characterized by a hydrological gradient. The meadows occur in two regions of the Greater Yellowstone Ecosystem (Gallatin and Teton) and were classified into six categories (M1–M6, designating hydric to xeric) based upon Satellite pour l’Observation de la Terre (SPOT) satellite imagery. Both regions have similar plant communities, but patch sizes of meadows are much smaller in the Gallatin region. We ...

The plan is required by the Oceans Act of 2008 to, among other things, be adaptive to evolving knowledge and understanding of the ocean environment. The plan’s Science Framework establishes a blueprint for future research and data acquisition and ensuring that the plan evolves and its management measures adapt to this new and enhanced information. As stated in Chapter 5 of the draft plan, an important part of the science framework is the development ...


Fire Disturbance, Forest Structure, And Stand Dynamics In Montane Forests Of The Southern Cascades, Thousand Lakes Wilderness, California, Usa, Matthew F. Bekker, Alan H. Taylor 2010 Brigham Young University

Fire Disturbance, Forest Structure, And Stand Dynamics In Montane Forests Of The Southern Cascades, Thousand Lakes Wilderness, California, Usa, Matthew F. Bekker, Alan H. Taylor

Wasatch Dendroclimatology Research

We examined tree diameter, age structure, and successional trends in 100 montane forest plots to identify the effects of variation in the return interval, severity, and extent of fires on forest structure and dynamics in the southern Cascade Range, California. We classified 100 forest plots into 8 groups based on stand structural characteristics. Median point fire return intervals were shortest in lower montane mixed conifer and Jeffrey pine–white fir stands (13-25 y) and upper montane red fir–white fir stands (14.5-19.5 y), intermediate in lodgepole pine stands (50-76.5 y), and longest in high-elevation red fir–mountain ...


Age Related Productivity And Consistency Of Nest Initiation Timing Of Wild Mallards In Eastern North Dakota, Timothy Charles Kimmel 2010 Louisiana State University and Agricultural and Mechanical College

Age Related Productivity And Consistency Of Nest Initiation Timing Of Wild Mallards In Eastern North Dakota, Timothy Charles Kimmel

LSU Master's Theses

Mallards Anas platyrhnchos are arguably the most researched waterfowl species in North America. They exhibit great flexibility in certain breeding metrics such as timing of nest initiation and clutch size. A study on captive female Mallards (Batt and Prince 1979) fed ad libitum, held in identical breeding compartments, and paired with the same mate in each year of the study exhibited substantial variation in the timing of nest initiation within a given year, yet some individual females demonstrated consistency in initiation date among years. My objective was to examine breeding metrics such as timing of nest initiation and clutch size ...


The Index Of Biological Integrity And The Bootstrap: Can Random Sampling Error Affect Stream Impairment Decisions?, Christine L. Dolph, Aleksey Y. Sheshukov, Christopher J. Chizinski, Bruce Vondracek, Bruce N. Wilson 2010 University of Minnesota

The Index Of Biological Integrity And The Bootstrap: Can Random Sampling Error Affect Stream Impairment Decisions?, Christine L. Dolph, Aleksey Y. Sheshukov, Christopher J. Chizinski, Bruce Vondracek, Bruce N. Wilson

Nebraska Cooperative Fish & Wildlife Research Unit -- Staff Publications

Multimetric indices, such as the Index of Biological Integrity (IBI), are increasingly used bymanagement agencies to determine whether surface water quality is impaired. However, important questions about the variability of these indices have not been thoroughly addressed in the scientific literature. In this study, we used a bootstrap approach to quantify variability associated with fish IBIs developed for streams in two Minnesota river basins. We further placed this variability into a management context by comparing it to impairment thresholds currently used in water quality determinations for Minnesota streams. We found that 95% confidence intervals ranged as high as 40 points ...

Multi-Decadal Surface Temperature Trends In East Antarctica Inferred From Borehole Firn Temperature Measurements And Geophysical Inverse Methods, Atsuhiro Muto 2010 University of Colorado at Boulder

Multi-Decadal Surface Temperature Trends In East Antarctica Inferred From Borehole Firn Temperature Measurements And Geophysical Inverse Methods, Atsuhiro Muto

Geography Graduate Theses & Dissertations

The climate trend of the Antarctic interior remains unclear relative to the rest of the globe because of a lack of long-term weather records. Recent studies by other authors utilizing sparse available records, satellite data, and models have estimated a significant warming trend in the near-surface air temperature in West Antarctica and weak and poorly constrained warming trend in East Antarctica for the past 50 years. In this dissertation, firn thermal profiling was used to detect multi-decadal surface temperature trends in the interior of East Antarctica where few previous records of any kind exist. The surface temperature inversion from firn ...


Assessing Supraglacial Water Volume And The Changing Dynamics Of The Surface Topography Near The Jakobshavn Glacier, Greenland, John Adler 2010 University of Colorado at Boulder

Assessing Supraglacial Water Volume And The Changing Dynamics Of The Surface Topography Near The Jakobshavn Glacier, Greenland, John Adler

Geography Graduate Theses & Dissertations

On the Greenland Ice Sheet (GIS), the effect of the melt season’s changing supraglacial lakes on outlet glacier discharge is not well understood. It is known that many supraglacial lakes drain rapidly during each melt season. While there are conflicting theories of the significance of supraglacial lake drainages towards enhancing ice sheet flow, it is highly important to quantify the actual water volume of supraglacial lakes since their drainage via crevasses or moulins enables the injection of melt water directly into the GIS. The 2008 Arctic MUltiSensor Cryospheric Observation eXperiment (Arctic MUSCOX) was the first scientific Unmanned Aircraft System ...


Data For Modelers--Helping Understand The Climate System, Mark A. Parsons 2010 University of Colorado at Boulder

Data For Modelers--Helping Understand The Climate System, Mark A. Parsons

Geography Graduate Theses & Dissertations

The Arctic is changing rapidly with dramatic local and global effect. To understand that change requires understanding the Arctic as a system. Models of different processes and at various scales are necessary tools for analyzing and understanding the Arctic system. Models are extremely diverse, yet they all require quality data. Through a series of case studies, augmented with ethnographic observation around the International Polar Year, this thesis examines how modelers assess, acquire, and prepare data for their models. By comparing specific case studies, common themes emerge that can be compared against broader observation. These themes, in turn, suggest data management ...


Climatological And Elevational Controls On Organic And Inorganic Nutrients In Stream Waters, Boulder Creek Watershed, Colorado Front Range, Jordan N. Parman 2010 University of Colorado at Boulder

Climatological And Elevational Controls On Organic And Inorganic Nutrients In Stream Waters, Boulder Creek Watershed, Colorado Front Range, Jordan N. Parman

Geography Graduate Theses & Dissertations

Due to short growing seasons, sparse vegetation, thin soils, and a harsh climate, the biota of high elevation ecosystems throughout the Colorado Front Range are sensitive to disturbance. These ecosystems are subject to two major drivers of environmental change: directional changes in climate and increasing inorganic nitrogen (N) deposition in wetfall. By analyzing long term climate records and water chemistry data, we investigate the role of climate and N deposition in determining nitrate export from Green Lakes Valley in the Colorado Front Range. We found that streamwater nitrate concentrations observed at the Green Lakes 4 (GL4) outlet have significantly increased ...
