Cnh: Fine-Scale Dynamics Of Human Adaptation In Coupled Natural And Social Systems: An Integrated Computational Approach Applied To Three Fisheries, James A. Wilson, James Acheson, Robert Steneck, Yong Chen, Teresa R. Johnson

University of Maine Office of Research Administration: Grant Reports

The purpose of this project is to gain a better understanding of the way competition between individual fishermen lead to the emergence of private incentives and informal social arrangements that are (or are not) consistent with conservation of the resource. These informal arrangements and incentives are important because they help us understand the extent to which private interests might strengthen or weaken on-going resource management and, consequently, the sustainability of coupled human and natural systems. The broad hypothesis driving the study is that the informal social structure that emerges from competitive interactions among fishermen reflects the particular circumstances of the …

Habitat Use Of The Key Largo Woodrat (Neotoma Floridana Smalli), Lauren J. Barth Nov 2014

Habitat Use Of The Key Largo Woodrat (Neotoma Floridana Smalli), Lauren J. Barth

FIU Electronic Theses and Dissertations

Key Largo woodrats are an endangered subspecies with an extremely limited habitat. This study sought to understand woodrat habitat preferences in order to guide management. Woodrats build stick nests from natural and artificial materials, so nest distribution and nest occupancy were used as indicators of preference. Distribution was determined by nest surveys, and remote cameras were used to assess occupancy. Forest structure, human disturbance, nest, and animal presence metrics were also collected. More nests were found along abandoned roads than along forest transects and more artificial nests were occupied than natural nests. These findings indicate that woodrats prefer areas with …

Planning For Adaptation To Climate Change: Lessons From The Us National Wildlife Refuge System, Robert L. Fischman, Vicky J. Meretsky, Alexei Babko, Michael Kennedy, Lei Liu, Michelle Robinson Nov 2014

Planning For Adaptation To Climate Change: Lessons From The Us National Wildlife Refuge System, Robert L. Fischman, Vicky J. Meretsky, Alexei Babko, Michael Kennedy, Lei Liu, Michelle Robinson

Articles by Maurer Faculty

US national wildlife refuges have recent, detailed management plans illustrating the state of planning for climate-change adaptation in protected areas. Discussion of and prescriptions for addressing climate change increased in refuge plans between 2005 and 2010 but decreased in 2011. The plans respond to some climate-change impacts on biodiversity and call for monitoring but with little clarity regarding how to act on monitoring results and scant attention to future changes in phenology and community composition. The threats posed by sea-level rise generated the best-developed plan prescriptions. Examples of excellent prescriptions provide models for future planning. Some decision-support tools, such as …

Ecology And Conservation Of Endangered Species In Sumatra: Smaller Cats And The Sumatran Rhinoceros (Dicerorhinus Sumatrensis) As Case Studies, Wulan Pusparini Aug 2014

Ecology And Conservation Of Endangered Species In Sumatra: Smaller Cats And The Sumatran Rhinoceros (Dicerorhinus Sumatrensis) As Case Studies, Wulan Pusparini

Masters Theses

While we should celebrate the bicentennial of naming the Sumatran rhinoceros (SR), the only extant population on earth might be on the island of Sumatra. Since Strien's 1986 study in Mamas Valley, Leuser, very little more has been learned about how this species distributed and what factors are influencing its extirpation. This study is the first conducted in Sumatra at an Island-wide scale. Using hierarchical models, I estimate the occurrence rates (%) and indices of abundance of SR on three remaining population areas: Leuser Landscape (LL) in 2007 (2.77%, 26 (CI 12-61)), Way Kambas (WK) in 2008 (33.58%, 27 (CI …

Historic Distribution And Ecology Of Tall-Grass Prairie In Western Canada, Darcy C. Henderson, Nicola Koper Aug 2014

Historic Distribution And Ecology Of Tall-Grass Prairie In Western Canada, Darcy C. Henderson, Nicola Koper

The Prairie Naturalist

Rapid settlement and agricultural development of western Canada in the late 1800s and early 1900s nearly eliminated the tall-grass prairie, and pre-empted a detailed description by ecologists. A combination of literature review and historical ecological analysis of soils, climate, and composition data are applied to estimate the historic distribution, and area occupied by tall-grass prairie in southern Manitoba and southeastern Saskatchewan, Canada. The resulting area estimate of 20,830 km2 is more than three times any previously reported value. Some confusion of terms from the first half of the 1900s, and the impact of invasive species on vegetation patterns observed …

Development Of A Public Education Website: Building Bridges Over Water, Angelina Mckee Jul 2014

Development Of A Public Education Website: Building Bridges Over Water, Angelina Mckee

Agricultural Education and Communication

Website created by Angelina McKee to educate the public about water resource issues. Water is the basic unit of life, water resources are the basis for what societies and ecosystems are founded upon. Water shortages and droughts are more prevalent in our ever-changing world. It is no shock that there are discrepancies between various stockholders on either sides of the dry riverbed. This senior project resulted in the development of a website that addresses global water resources, water use in California, water conservation, and water allocation. The website informs the public on water resources and related issues and will hopefully …

Understanding The Role Of Trust In Cooperation With Natural Resources Institutions, Joseph A. Hamm May 2014

Understanding The Role Of Trust In Cooperation With Natural Resources Institutions, Joseph A. Hamm

Department of Psychology: Dissertations, Theses, and Student Research

This dissertation investigates the role of trust in predicting cooperation with a natural resources management institution. It begins with an exploration of the legal landscape against which the relationship between land owners and natural resources management institutions is contextualized, presents a review of the often ostensibly disparate trust literature and a framework for its integration, and proposes and tests a model of trust and cooperation in the natural resources context. The results provide mixed support for the model as proposed but confirm the importance of trust in this context and suggest implications for policy, especially the potential importance of increasing …

Late Pleistocene And Holocene Bison Of Grand Canyon And Colorado Plateau: Implications From The Use Of Paleobiology For Natural Resource Management Policy, Jeffrey M. Martin May 2014

Late Pleistocene And Holocene Bison Of Grand Canyon And Colorado Plateau: Implications From The Use Of Paleobiology For Natural Resource Management Policy, Jeffrey M. Martin

Electronic Theses and Dissertations

Bison spp. (bison) fossils are scarce on the Colorado Plateau, especially within the greater Grand Canyon region. Because of the poor fossil record for bison on the plateau and in Grand Canyon National Park, various resource managers have surreptitiously designated bison a nonnative and human-introduced species. The lack of evidence for bison seems to be the result of collection bias rather than a true lack of bison remains. Today, Grand Canyon National Park has a neighboring herd of 350 bison that have meandered unwantedly onto National Park lands from neighboring Forest Service and State of Arizona lands. This study spatiotemporally …

School of Natural Resources: Faculty Publications

Abstract The pygmy hippopotamus Choeropsis liberiensis is an Endangered species found only in the Upper Guinea rainforests of West Africa. Using a two-phase approach, with initial semi-structured interviews followed by more extensive questionnaires, we examined local residents’ awareness of and attitudes towards the pygmy hippopotamus along the Moa River near Tiwai Island Wildlife Sanctuary in Sierra Leone. The interviews and questionnaires addressed human–hippopotamus interactions, local knowledge and awareness of pygmy hippopotamus ecology and behaviour, and public attitudes towards hippopotamus conservation. Overall, 22% of questionnaire respondents acknowledged benefits related to hippopotamus conservation; factors affecting the perception of benefits included age, livestock …

Water projects designed to extract fresh water for local urban, industrial and agricultural use throughout rivers and estuaries worldwide have contributed to the fragmentation and degradation of suitable habitat for native fishes. The number of water diversions located throughout the Sacramento–San Joaquin watershed in California’s Central Valley exceeds 3300, and the majority of these are unscreened. Many anadromous fish species are susceptible to entrainment into these diversions, potentially impacting population numbers. In the laboratory, juvenile green sturgeon (Acipenser medirostris) have been shown to have high entrainment rates into unscreened diversions compared with those of other native California fish …

Conservation Without Nature: The Trouble With In Situ Versus Ex Situ Conservation, Irus Braverman Jan 2014

Conservation Without Nature: The Trouble With In Situ Versus Ex Situ Conservation, Irus Braverman

Journal Articles

Although understudied in academia and mostly unheard of by the general public, the in situ/ex situ dichotomy has shaped — and still very much shapes — the development of the nature conservation movement and its institutional alliances in the last few decades. Latin for “in” and “out” of place, the in/ex situ dichotomy often stands for the seemingly less scientific dichotomy between wild nature and captivity. Drawing on ethnographic engagements with zoo professionals and wildlife managers, this article explores the evolution of the in situ/ex situ dyad in nature conservation, which traverses the worlds of dead and live matter, artificilia …

Biological Sciences Faculty Publications

Marine habitats are in decline worldwide, precipitating a strong interest in marine conservation. The use of biogeographic data to designate ecoregions has had significant impacts on terrestrial conservation efforts. However, classification of marine environments into ecoregions has only become available in the last several years, based on biogeographic data supplemented by geomorphology, ocean currents, and water temperatures. Here we use a comparative phylogeographic approach to test for concordant phylogeographic patterns in three closely related species of Tridacna giant clams across the Coral Triangle, the most biodiverse marine region in the world and one of the most threatened. Data from a …
