Emerging Hot Spot Analysis To Indicate Forest Conservation Priorities And Efficacy On Regional To Continental Scales: A Study Of Forest Change In Selva Maya 2000-2020, Nicholas Cuba, Laura A. Sauls, Anthony J. Bebbington, Denise Humphreys Bebbington, Avecita Chicchon, Pilar Delpino Marimón, Oscar Diaz, Susanna Hecht, Susan Kandel, Tracey Osborne, Rebecca Ray, Madelyn Rivera, John Rogan, Viviana Zalles

Geography

Despite the importance of preserving contiguous tropical forest areas to maintain biodiversity and terrestrial carbon stocks, methodological challenges continue to hinder broad-scale analysis of threats to these forests. Emerging Hot Spot Analysis (EHSA) is a spatial-statistical method that conveys complex information about the temporal dynamics of deforestation across a range of moderate to coarse spatial scales. Using Global Forest Change (GFC) data as inputs, EHSA produces spatially comprehensive, gridded outputs that represent a standardized, reproduceable way to instantiate contiguous forest tracts as spatial objects. Doing so allows aggregation of other GFC-derived values and analysis of alternative geographic configurations besides sub-national …

Protecting Biodiversity In British Columbia: Recommendations For Developing Species At Risk Legislation, Alana R. Westwood, Sarah P. Otto, Arne Mooers, Chris Darimont, Karen E. Hodges, Chris Johnson, Brian M. Starzomski, Cole Burton, Kai M. A. Chan, Marco Festa-Bianchet, Shaun Fluker, Sumeet Gulati, Aerin L. Jacob, Dan Kraus, Tara G. Martin, Wendy J. Palen, John D. Reynolds, Jeannette Whitton

Threatened and Endangered Animal Populations Collection

British Columbia has the greatest biological diversity of any province or territory in Canada. Yet increasing numbers of species in British Columbia are threatened with extinction. The current patchwork of provincial laws and regulations has not effectively prevented species declines. Recently, the Provincial Government has committed to enacting an endangered species law. Drawing upon our scientific and legal expertise, we offer recommendations for key features of endangered species legislation that build upon strengths and avoid weaknesses observed elsewhere. We recommend striking an independent Oversight Committee to provide recommendations about listing species, organize Recovery Teams, and monitor the efficacy of actions …

The International Whaling Commission—Beyond Whaling, Andrew J. Wright, Mark P. Simmonds, Barbara Galletti Vernazzani

Wildlife Population Management Collection

Since its establishment in 1946 as the international body intended to manage whaling, the International Whaling Commission (IWC) has expanded its areas of interest to ensure the wider conservation of whales. Several key conservation topics have been taken forward under its auspices including climate change, chemical and noise pollution, marine debris and whale watching. Work on each of these topics at the IWC has grown substantially since the 1990s and remains ongoing. Important developments were the establishment of the Standing Working Group on Environmental Concerns in 1996 and the IWC’s Conservation Committee in 2003. Trying to address this diverse set …

When The Hunt Is Over: Culture And Conservation In Kazakh Eagle Falconry, Nolan R. Ebner

Independent Study Project (ISP) Collection

The last large scale practice of falconry that uses Golden Eagles takes place in Bayan- Ulgii, Mongolia. Recent media exposure allowed for the development of a tourism industry in the region that culminates in two annual festivals celebrating the cultural heritage. Modern eagle falconry practices have been shown to deviate from traditional hunting and training methods. While Golden Eagles are listed with a regional conservation status of Least Concern by the Mongolian Red List, these new practices place the health of Golden Eagle populations in the region at risk, especially as tourism continues to grow. Furthermore, a changing environmental climate …

Grizzly Bear Monitoring By The Heiltsuk People As A Crucible For First Nation Conservation Practice, William G. Housty, Anna Noson, Gerald W. Scoville, John Boulanger, Richard M. Jeo, Chris T. Darimont, Christopher E. Filardi

Wildlife Population Management Collection

Guided by deeply held cultural values, First Nations in Canada are rapidly regaining legal authority to manage natural resources. We present a research collaboration among academics, tribal government, provincial and federal government, resource managers, conservation practitioners, and community leaders supporting First Nation resource authority and stewardship. First, we present results from a molecular genetics study of grizzly bears inhabiting an important conservation area within the territory of the Heiltsuk First Nation in coastal British Columbia. Noninvasive hair sampling occurred between 2006 and 2009 in the Koeye watershed, a stronghold for grizzly bears, salmon, and Heiltsuk people. Molecular demographic analyses revealed …

A Framework To Evaluate Wildlife Feeding In Research, Wildlife Management, Tourism And Recreation, Sara Dubois, David Fraser

Wildlife Population Management Collection

Feeding of wildlife occurs in the context of research, wildlife management, tourism and in opportunistic ways. A review of examples shows that although feeding is often motivated by good intentions, it can lead to problems of public safety and conservation and be detrimental to the welfare of the animals. Examples from British Columbia illustrate the problems (nuisance animal activity, public safety risk) and consequences (culling, translocation) that often arise from uncontrolled feeding. Three features of wildlife feeding can be distinguished: the feasibility of control, the effects on conservation and the effects on animal welfare. An evaluative framework incorporating these three …

Interactions Between Short-Beaked Common Dolphin (Delphinus Delphis) And The Winter Pelagic Pair-Trawl Fishery Ff Southwest England (Uk), Marijke N. De Boer, James T. Saulino, Mardik F. Leopold, Peter J.H. Reijnders, Mark P. Simmonds

Aquaculture Collection

During offshore and onshore studies (2004 to 2009), the interactions between pair-trawls and short-beaked common dolphins (Delphinus delphis) were studied to better understand the impact of bycatch. A ‘hotspot’ area where pair-trawls overlapped with high dolphin abundance was identified. We made comparisons between boat-based data collected in absence and presence of pair-trawlers. The relative abundance and group-size of dolphins was significantly higher in the presence of pair-trawlers. Dolphins were observed associating with towing and hauling procedures. Significantly, more carcasses occurred in areas with hauling-activity than those without. Body-temperatures obtained from carcasses found near operating pair-trawlers indicated that bycatch mostly occurred …

Whaling: Don’T Trade The Moratorium Away, Mark Peter Simmonds, Sue Fisher

Conservation Collection

In their proposal to allocate ‘whale shares’ to both whalers and conservationists as an alternative to the International Whaling Commission (IWC) moratorium on commercial whaling, Christopher Costello and colleagues overlook several factors (Nature 481, 139–140; 2012).

Impacts Of Urbanisation On The Native Avifauna Of Perth, Western Australia, Robert Davis, C Gole, Jd Roberts

Research outputs 2012

Urban development either eliminates, or severely fragments, native vegetation, and therefore alters the distribution and abundance of species that depend on it for habitat. We assessed the impact of urban development on bird communities at 121 sites in and around Perth, Western Australia. Based on data from community surveys, at least 83 % of 65 landbirds were found to be dependent, in some way, on the presence of native vegetation. For three groups of species defined by specific patterns of habitat use (bushland birds), there were sufficient data to show that species occurrences declined as the landscape changed from variegated …

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

Antioch University 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 …

The town center is the hub of the town where the major community buildings are such as the elementary and high schools, town hall, the town library, and most of the public recreation fields. Once the overall greenway …

Microclimate Preferences Of The Grey-Headed Flying Fox (Pteropus Poliocephalus) In The Sydney Region, Stephanie T. Snoyman, Culum Brown

Sentience Collection

The population size of the grey-headed flying fox (Pteropus poliocephalus) has decreased dramatically as a result of a variety of threatening processes. This species spends a great proportion of time in roosting large social aggregations in urban areas, causing conflict between wildlife and humans. Little is known about why these bats choose to roost in some locations in preference to others. Roost selection by cave-dwelling bats can be greatly influenced by microclimatic variables; however, far less is known about microclimate selection in tree-roosting species despite the direct management implications. This study aimed to determine the microclimate characteristics of P. poliocephalus …

Do Zoos And Aquariums Promote Attitude Change In Visitors? A Critical Evaluation Of The American Zoo And Aquarium Study, Lori Marino, Scott O. Lilienfeld, Randy Malamud, Nathan Nobis, Ron Broglio

Zoos and Aquariums Collection

Modern-day zoos and aquariums market themselves as places of education and conservation. A recent study conducted by the American Zoo and Aquarium Association (AZA) (Falk et al., 2007) is being widely heralded as the first direct evidence that visits to zoos and aquariums produce long-term positive effects on people’s attitudes toward other animals. In this paper, we address whether this conclusion is warranted by analyzing the study’s methodological soundness. We conclude that Falk et al. (2007) contains at least six major threats to methodological validity that undermine the authors’ conclusions. There remains no compelling evidence for the claim that zoos …

Participatory Planning For A Promised Land: Citizen-Led, Comprehensive Land Use Planning In New York’S Adirondack Park, Ann Hope Ruzow Holland

Antioch University Dissertations & Theses

New York’s Adirondack Park is internationally recognized for its biological diversity. Greater in size than Yellowstone, Everglades, Glacier, and Grand Canyon National Park combined, the Adirondacks are the largest protected area within the Northern Appalachian/Acadian Eco-Region and within the contiguous United States. Ecologists, residents of the Park, and others are concerned about rapid land use change occurring within the borders of the Park. Almost half of the six million acres encompassed by the Park boundary is privately-owned, where 80% of land use decisions fall within the jurisdiction of local governments. The comprehensive planning process of one such local government, the …

Dwelling, Walking, Serving: Organic Preservation Along The Camino De Santiago Pilgrimage Landscape, Mercedes Chamberlain Quesada-Embid

Antioch University Dissertations & Theses

This study is an exploration of the people and the landscape of the well-known Camino de Santiago pilgrimage route. Although there are many routes that make up the entirety of the pilgrimage, this research is specifically focused on the landscape of the Camino Francés, or French Route, in northern Spain. The path has been written about in many ways and for a myriad of reasons since it became affiliated with the Christian tradition in the early ninth century. This research, however, is different. By way of an environmental history and hermeneutic approach, an investigation of the interrelated and overlapping human …

Population Assessment Of Khulan (Equus Hemionus) In Mongolia, Badamjav Lkhagvasuren

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

The data presented here suggest that 18,411 (± 224) khulan inhabit southern Mongolia with a density of 1.4 individuals per 1,000 km² within the 157,525 km² territory of its actual distribution. The Dornogobi province contains the highest number of khulan with a mere 67%, while 20% are found in the Ömnögobi province, 12% are in Djungarian Gobi and only 1% in the Gobi-Altay and Bayankhongor provinces. According to the proportion of foals and yearlings within each aimag, the Dornogobi, Ömnögobi east and Khovd populations have an average reproduction rate.

Kulan (Equus Hemionus Pallas 1775) In Turkmenistan, Victor S. Lukarevskiy, Yu. K. Gorelov

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

The kulan (Equus hemionus kulan) is the only odd-toed ungulate left in the wild in northern Eurasia. In the 1930s, the kulan survived in southern Turkmenistan only. In the 1940s, kulans were found only in an area named Badkhyz in Turkmenistan. To conserve the last natural population of this subspecies of kulan the Badkhyz Natural Reserve was established in 1941. The historical and contemporary distribution, fluctuation in numbers, conservation and sci research of kulan populations in the Badkhyz Natural reserve are reviewed in this paper.

The Emerging Dziggetai (Equidae: Equus Hemionus Pallas): An Illustrated History Of Taxonomic Concepts For The Identification, Classification, And Distribution Of Hemiones From Central Asia, Arnd Schreiber

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

The history of the discovery and the exploration of the hemione populations (Equus hemionus PALLAS) from Central Asia (Mongolia, northwest China, northeast Tibet, Kazakhstan, and Russian Siberia) from the 13th century to approximately 1950 are compiled with the aim to provide materials for a taxonomic and population genetic revision of the dziggetais. Data on their phenotypic differentiation, historical distribution status, and their husbandry history in European zoological gardens, are reviewed, as is the gradual emergence of concepts of how to identify and to classify these populations. Hemiones were an important historical case in the discussion of how to represent …

Wild Bactrian Camel Conservation, Richard P. Reading, Evan S. Blumer, Henry Mix, Jadamsuren Adiya

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

The wild Bactrian camel (Camelus bactrianus ferus) is critically endangered throughout its range in China and Mongolia. Yet, wild camels remain poorly understood, with knowledge derived primarily from a few short studies and anecdotal information. We initiated a wild camel conservation project to determine the reasons for camel decline and to develop a program to address those problems.

We are employing satellite telemetry to gather data on wild camel movement patterns, home ranges, habitat use, and sources of mortality. We are also collecting feces from camels and wolves to determine important forage plants and to begin to assess …

Agroforestry, Elephants, And Tigers: Balancing Conservation Theory And Practice In Human-Dominated Landscapes Of Southeast Asia, Philip J. Nyhus, R L. Tilson

Faculty Scholarship

Large mammal populations theoretically are best conserved in landscapes where large protected areas are surrounded by buffer zones, connected by corridors, and integrated into a greater ecosystem. Multi-use buffer zones, including those containing complex agroforestry systems, are promoted as one strategy to provide both economic benefits to people and conservation benefits to wildlife. We use the island of Sumatra, Indonesia to explore the benefits and limitations of this strategy. We conclude that conservation benefits are accrued by expanding the habitat available for large mammals but more attention needs to be focused on how to reduce and respond to human–wildlife conflict …

Striving For Common Ground: Humane And Scientific Considerations In Contemporary Wildlife Management, Stephen R. Kellert

Nature Collection

Although there is a diversity of opinion about how to view the relationship between humans and wildlife, recent political pressures from the current administration make it mandatory that these diverse groups coalesce to use their combined leverage to halt the planned incursions into the remaining habitats of wildlife. It is also important to begin to see nature as a complex and interrelated whole, and to respect the integrity of that whole, rather than simply select individual species for affection and protection.

Bureaucracy And Wildlife: A Historical Overview, Edward E. Langenau

Laws and Legislation Collection

This paper provides a framework for understanding the Government's position on many wildlife topics, including humane ethics. The historical role of Government in wildlife conservation is traced in relation to pertinent theories of bureaucracy. It is shown that Government involvement in wildlife conservation increased through successive stages of change because of interest group activity.

These periods of increased Government involvement in wildlife matters are shown to have followed periods of resource exploitation. Recurrent cycles of exploitation, accompanied by economic prosperity, have then been followed by attitudes favorable to conservation and political activism. This, in turn, has produced periods of backlash …

An Overview Of Zoo Goals And Exhibition Principles, Randall L. Eaton

Zoos and Aquariums Collection

It is not uncommon among progressive-minded zoo professionals these days to hear disdain for the function of zoos as recreational. This attitude is understandable in that traditionally, zoos have done little but offer amusement along with parklands or picnic facilities. The progressive zoo person sets his or her goals above the old-fashioned recipe of crowding as many exotic animals as possible into an amusement-oriented menagerie to an authentic theme for exhibition intended to educate the public, offer research possibilities, and preserve and propagate species. Nevertheless, recreation remains a primary function of zoos. Most zoo visitors do not seek education in …
