Introduction: Social-Ecological Resilience And Law, Ahjond S. Garmestani, Craig R. Allen, Craig Anthony Arnold, Lance H. Gunderson Jan 2014

Introduction: Social-Ecological Resilience And Law, Ahjond S. Garmestani, Craig R. Allen, Craig Anthony Arnold, Lance H. Gunderson

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Environmental law is intimately connected to ecological concepts and understanding. The legal instruments, institutions, and administration of law in the United States are predicated on assumptions that nature is globally stable and that the inherent variability in ecological systems is bounded. This current legal framework is based upon an understanding of ecological systems operating near an equilibrium, or if disturbed, moving back toward an equilibrium. Such assumptions make much current environmental law ill-suited for many pressing environmental issues (Ruhl 1999; Garmestani et al. 2009; Craig 2010; Verchick 2010; Benson and Garmestani 2011). Emerging environmental challenges, such as cross-boundary water governance …


Self-Confidence Of Anglers In Identification Of Freshwater Sport Fish, Christopher J . Chizinski, D. R. Martin, K. L. Pope Jan 2014

Self-Confidence Of Anglers In Identification Of Freshwater Sport Fish, Christopher J . Chizinski, D. R. Martin, K. L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Although several studies have focused on how well anglers identify species using replicas and pictures, there has been no study assessing the confidence that can be placed in angler’s ability to identify recreationally important fish. Understanding factors associated with low self-confidence will be useful in tailoring education programmes to improve self-confidence in identifying common species. The purposes of this assessment were to quantify the confidence of recreational anglers to identify 13 commonly encountered warm water fish species and to relate self-confidence to species availability and angler experience. Significant variation was observed in anglers selfconfidence among species and levels of self-declared …


Toxicity Of Copper Sulfate And Rotenone To Chinese Mystery Snail (Bellamya Chinensis), Danielle M. Haak, Bruce J. Stephen, Robert A. Kill, Nicholas A. Smeenk, Craig R. Allen, Kevin L. Pope Jan 2014

Toxicity Of Copper Sulfate And Rotenone To Chinese Mystery Snail (Bellamya Chinensis), Danielle M. Haak, Bruce J. Stephen, Robert A. Kill, Nicholas A. Smeenk, Craig R. Allen, Kevin L. Pope

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The Chinese mystery snail (Bellamya chinensis) is a freshwater snail native to Southeast Asia, Japan, and Russia and is currently classified as an invasive species in at least 27 states in the USA. The species tolerates a wide range of environmental conditions, making management of established populations difficult. We tested the efficacy of two traditional chemical treatments, rotenone and copper sulfate, on the elimination of adult Chinese mystery snails in laboratory experiments. All snails (N=50) survived 72-hour exposure to rotenone-treated lake water, and 96% (N=25) survived 72-hour exposure to pre-determined rotenone concentrations of 0.25, 2.5, and 25.0 mg/L. …


Transdisciplinary Application Of Cross-Scale Resilience, Shana M. Sundstrom, David G. Angeler, Ahjond S. Garmestani, Jorge-H. Garcia, Craig R. Allen Jan 2014

Transdisciplinary Application Of Cross-Scale Resilience, Shana M. Sundstrom, David G. Angeler, Ahjond S. Garmestani, Jorge-H. Garcia, Craig R. Allen

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The cross-scale resilience model was developed in ecology to explain the emergence of resilience from the distribution of ecological functions within and across scales, and as a tool to assess resilience. We propose that the model and the underlying discontinuity hypothesis are relevant to other complex adaptive systems, and can be used to identify and track changes in system parameters related to resilience. We explain the theory behind the cross-scale resilience model, review the cases where it has been applied to non-ecological systems, and discuss some examples of social-ecological, archaeological/ anthropological, and economic systems where a cross-scale resilience analysis could …


Status Of Native Stream Fishes Within Selected Protected Areas Of The Niobrara River In Western Nebraska, Jonathan J. Spurgeon, Richard H. Stasiak, George R. Cunningham, Kevin L. Pope, Mark A. Pegg Jan 2014

Status Of Native Stream Fishes Within Selected Protected Areas Of The Niobrara River In Western Nebraska, Jonathan J. Spurgeon, Richard H. Stasiak, George R. Cunningham, Kevin L. Pope, Mark A. Pegg

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Lotic systems within the Great Plains are characterized by highly fl uctuating conditions through both space and time. Fishes inhabiting these systems have adopted specifi c life- history strategies to survive in such environments; however, anthropogenic disturbance to prairie streams has resulted in declines and extirpation of many native stream fi shes. Terrestrial protected areas (i.e., parks and reserves) are designated to support native fl ora and fauna and, it is assumed, to provide protection to native fi shes. We assessed the presence and relative abundance of stream fi sh populations within protected areas along the Niobrara River in western …


Habitat Structure And Body Size Distributions: Cross-Ecosystem Comparison For Taxa With Determinate And Indeterminate Growth, Kirsty L. Nash, Craig R. Allen, Chris Barichievy, Magnus Nyström, Nicholas A. J. Graham Jan 2014

Habitat Structure And Body Size Distributions: Cross-Ecosystem Comparison For Taxa With Determinate And Indeterminate Growth, Kirsty L. Nash, Craig R. Allen, Chris Barichievy, Magnus Nyström, Nicholas A. J. Graham

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Habitat structure across multiple spatial and temporal scales has been proposed as a key driver of body size distributions for associated communities. Thus, understanding the relationship between habitat and body size is fundamental to developing predictions regarding the infl uence of habitat change on animal communities. Much of the work assessing the relationship between habitat structure and body size distributions has focused on terrestrial taxa with determinate growth, and has primarily analysed discontinuities (gaps) in the distribution of species mean sizes (species size relationships or SSRs). The suitability of this approach for taxa with indeterminate growth has yet to be …


Consuming Fire Ants Reduces Northern Bobwhite Survival And Weight Gain, P. Evans Myers, Craig R. Allen, Hannah E. Birge Jan 2014

Consuming Fire Ants Reduces Northern Bobwhite Survival And Weight Gain, P. Evans Myers, Craig R. Allen, Hannah E. Birge

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Northern bobwhite quail, Colinus virginianus (L.) (Galliformes: Odontophoridae), population declines are well documented, but pinpointing the reasons for these decreases has proven elusive. Bobwhite population declines are attributed primarily to loss of habitat and land use changes. This, however, does not entirely explain population declines in areas intensively managed for bobwhites. Although previous research demonstrates the negative impact of red imported fire ant (Solenopsis invicta Buren) (Hymenoptera: Formicidae) on northern bobwhites, the mechanisms underlying this effect are largely unknown. To meet the protein demands of early growth and development, bobwhite chicks predominantly consume small insects, of which ants are …


Quantifying Spatial Scaling Patterns And Their Local And Regional Correlates In Headwater Streams: Implications For Resilience, Emma Göthe, Leonard Sandin, Craig R. Allen, David G. Angeler Jan 2014

Quantifying Spatial Scaling Patterns And Their Local And Regional Correlates In Headwater Streams: Implications For Resilience, Emma Göthe, Leonard Sandin, Craig R. Allen, David G. Angeler

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The distribution of functional traits within and across spatiotemporal scales has been used to quantify and infer the relative resilience across ecosystems. We use explicit spatial modeling to evaluate within- and cross-scale redundancy in headwater streams, an ecosystem type with a hierarchical and dendritic network structure. We assessed the cross-scale distribution of functional feeding groups of benthic invertebrates in Swedish headwater streams during two seasons. We evaluated functional metrics, i.e., Shannon diversity, richness, and evenness, and the degree of redundancy within and across modeled spatial scales for individual feeding groups. We also estimated the correlates of environmental versus spatial factors …

Development And Application Of A Gis-Based Long Island Sound Eelgrass Habitat Suitability Index Model, Jamie M.P. Vaudrey, Justin Eddings, Christopher Pickerell, Lorne Brousseau, Charles Yarish

Department of Marine Sciences

The primary objectives of the Eelgrass Habitat Suitability Index Model (EHSI Model) are to assist in the evaluation of sites being considered for eelgrass restoration efforts in the Long Island Sound (LIS) area and to identify areas where water quality issues reduce or eliminate the potential for natural eelgrass colonization. To achieve this goal, geospatial processing of data available from the Long Island Sound area was conducted using ArcGIS v10.0 including the 3D Analyst and Spatial Analyst extensions. The result is a series of maps presented in this report and a GIS-based model available for users to interact with the …

Global Fossil Energy Markets And Climate Change Mitigation: An Analysis With Remind, Nico Bauer, Ioanna Mouratiadou, Gunnar Luderer, Lavinia Baumstark, Robert J. Brecha, Ottmar Edenhofer, Elmar Kriegler Oct 2013

Global Fossil Energy Markets And Climate Change Mitigation: An Analysis With Remind, Nico Bauer, Ioanna Mouratiadou, Gunnar Luderer, Lavinia Baumstark, Robert J. Brecha, Ottmar Edenhofer, Elmar Kriegler

Physics Faculty Publications

We analyze the dynamics of global fossil resource markets under different assumptions for the supply of fossil fuel resources, development pathways for energy demand, and climate policy settings. Resource markets, in particular the oil market, are characterized by a large discrepancy between costs of resource extraction and commodity prices on international markets. We explain this observation in terms of (a) the intertemporal scarcity rent, (b) regional price differentials arising from trade and transport costs, (c) heterogeneity and inertia in the extraction sector. These effects are captured by the REMIND model. We use the model to explore economic effects of changes …


Mongolian National Parks: Competing Interests And Institutional Viability In A Still Emerging Protected Areas System, Kieryn Wurts Oct 2013

Mongolian National Parks: Competing Interests And Institutional Viability In A Still Emerging Protected Areas System, Kieryn Wurts

Independent Study Project (ISP) Collection

In Mongolia, 17% of the total landmass is designated as one of four kinds of “protected areas”—Strictly protected areas, national parks, nature reserves, and natural historical monuments. This study focuses primarily on national parks as a civil institution, through on the ground interviewing of ten individuals employed in the protected areas system, field-notes and observations, and community surveying totaling 38 respondents at two research locations, Hustai-Nuruu National Park and Lake Khovsgol National Park. Protected areas are constructed civil spaces, and as a result are sites of competing societal interests--the interests of scientists and conservationists, of tourism and business interests, and …


Vulnerability, Environmental Security, And Adaptation Awareness In Samoa, Katie Williams Oct 2013

Vulnerability, Environmental Security, And Adaptation Awareness In Samoa, Katie Williams

Independent Study Project (ISP) Collection

Climate change remains a prevalent problem for today’s international community, particularly for Pacific Island countries. This study examines the current influence of climate change on Samoa by looking at the three tenets of vulnerability: exposure, sensitivity, and adaptive capacity. These aspects of climatic change correlate and build off one another, ultimately elucidating the basic vulnerability of any given region. It also analyzes how environmentally secure Samoa is and will be, using Thomas Homer- Dixon’s theory on climate change and conflict. Finally, this paper seeks to outline the current system of adaptation awareness that exists between government, community and foreign aid …
