Antarctic Tourists, Wildlife and the Environment: Attractions and Reactions to Antarctica AgEcon
Tisdell, Clement A.; Wilson, Clevo.
Provides background on the development and nature of Antarctic tourism and associated environmental issues, as well as agreements and regulations affecting environmental management in Antarctica. Following an outline of the survey methodology and provision of information on the socioeconomic profiles of the respondents, results of a survey of Antarctic tourists on the Russian registered ship the ‘Akademik Ioffe’ are reported. The importance of Antarctic wildlife as an attraction for these Antarctic tourists is then given particular attention. The study considers amongst other things how important Antarctic wildlife was in convincing these tourists to undertake their trip to Antarctica, the importance to the tourists of seeing different species of...

Bioeconomic Model of Community Incentives for Wildlife Management Before and After CAMPFIRE AgEcon
Fischer, Carolyn; Muchapondwa, Edwin; Sterner, Thomas.
This paper formulates a bioeconomic model to analyze community incentives for wildlife management under benefit-sharing programs like the Communal Areas Management Programme for Indigenous Resources (CAMPFIRE) in Zimbabwe. Two agents influence the wildlife stock: a parks agency determines hunting quotas, and a local community chooses to either aid or discourage outside poachers. Wildlife generates revenues from hunting licenses and tourism; it also intrudes on local agriculture. We consider two benefit-sharing regimes: shares of wildlife tourism rents and shares of hunting licenses. Resource sharing does not necessarily improve community welfare or incentives for wildlife conservation. Results depend on the exact design of the benefit shares, the size of...

CONTRACTING OVER COMMON PROPERTY: COST-SHARE CONTRACTS FOR PREDATOR CONTROL AgEcon
Yoder, Jonathan K..
Predator control cost-share contracts among livestock producers in North America date back to 1630. A model is developed which provides refutable implications for the structure and distribution of these contracts over time and space. Historical and contemporary state and county level data on sheep producer coyote control generally support the model.

Contribution of the wildlife in ecological restoration projects in Brazil PFB - Pesquisa Florestal Brasileira
Campos, Wanuza Helena; Miranda Neto, Aurino; Peixoto, Helberth José Cardoso; Godinho, Leandro Braga; Silva, Elias.
The success in the process of restoration and maintenance of the dynamics of an ecosystem is highly dependent on the capacity of species to promote interspecific interactions among the various life forms. These interactions create a favorable environment for the ecological restoration of degraded ecosystems. Thus, by review the literature, the objective of this study is to report the contribution and use of different animal groups in carrying out ecological restoration projects in Brazil. The fruit-eating birds and mammals and also other animals such as reptiles, fish and insects have been highlighted as tools to aid environmental ecological restoration projects. Techniques for attracting animals and consequent arrival of seedlings in a degraded ecosystem...

DEPREDATION CLAIM BEHAVIOR AND TOLERANCE OF WILDLIFE IN WYOMING AgEcon
Van Tassell, Larry W.; Yang, Bozheng; Phillips, Clynn.
Wyoming Game and Fish Department depredation payments were established to increase landowner tolerance toward, and this the supply of, certain types of wildlife. This study examined how socio-economic and demographic characteristics of farmers and ranchers in Wyoming relate to tolerance toward wildlife and depredation claim submission. The severity of depredation and landowner satisfaction with the depredation policy were evaluated. The financial stability and economic intent of farmers and ranchers significantly influenced tolerance toward wildlife. Landowners tended to be less tolerant of depredation ensuing from elk. The complexity of the submission process was a deterrent to damage claim submissions.

Dieta e nutricao de crocodilianos. Infoteca-e
SANTOS, S.A..
A familia Crocodylidae inclui tres subfamilias: Crocodylinae, Alligatorinae e Gavialinae (Bellairs, 1987). Nessas, existem 22 especies de crocodilianos reconhecidas, das quais 15 sao usadas comercialmente para manufatura de artigos de luxo. No mundo em geral, os crocodilianos estao sendo aproveitados economicamente de tres formas: (1) "wild harvest" - manejo extensivo na natureza, geralmente seguindo criterios de extracao e monitoramento; (2) "ranching" - os ovos ou filhotes sao apanhados na natureza e criados ate o tamanho de abate e (3) "farming" - criacao englobando todo o ciclo reprodutivo da especie (Campos et al., 1994). O interesse pela criacao de jacares em cativeiro tem aumentado no Brasil e em muitos paises. No entanto, os criadores tem...

Dynamic Processes in Contingent Valuation: A Case Study Involving the Mahogany Glider AgEcon
Tisdell, Clement A.; Wilson, Clevo; Swarna Nantha, Hemanath.
This paper reports the results of an experiment involving a sample of 204 members of the public who were assessed on three occasions about their willingness to pay for the conservation of the mahogany glider. They were asked this question prior to information being provided to them about the glider and other focal wildlife species; after such information was provided, and finally after participants had had an opportunity to see live specimens of this glider. The mean willingness to pay of the relevant samples are compared and found to show significant variations. Theories are considered that help explain the dynamics of these variations. Serious concerns are raised about the capacity of information provision to reveal ‘true’ contingent valuations of public...

Economics of Controlling Vertebrate Wildlife: the Pest-Asset Dichotomy and Environmental Conflict AgEcon
Tisdell, Clement A..
Some wildlife species are agricultural pests (or otherwise a problem) but their populations are often valued by other than agriculturalists or by those not adversely affected by them directly. For non-farmers, the population levels of such wildlife are frequently pure public goods. This is one source of market failure in the economically optimal social control of an (agricultural) pest of this type. Secondly, if the species is geographically mobile, externalities occur between farmers (or other individuals) in the control of the species, and individuals ignore these spillovers in controlling pest species. Simple analysis is used to show that depending on the relative strength of these opposing types of market failure, farmers (or others) may excessively...

Effects of social change on wildlife consumption taboos in northeastern Madagascar Ecology and Society
Golden, Christopher D; Harvard School of Public Health, Department of Environmental Health; Wildlife Conservation Society, Wildlife Health & Health Policy, HEAL (Health & Ecosystems: Analysis of Linkages) Program; golden@hsph.harvard.edu; Comaroff, Jean; Departments of African and African American Studies and Anthropology, Harvard University; jeancomaroff@fas.harvard.edu.
In Madagascar, the constellation of taboos serves as a form of informal regulatory institution and is foundational to Malagasy culture, regardless of class, ethnic group affiliation, and educational background. Many researchers have credited rapid social change as a crucial mechanism for disturbing taboos. Others suggest that taboos are innately historical. However, very little empirical research has assessed the effects of social change on taboos or quantified the stability of taboo systems over time. Here, we use a case study of the ensemble of taboos in northeastern Madagascar, still a critical aspect of social life there, as a lens through which we investigate its degree of stability over time. Our aim was: (1) to describe the food taboos of local...

Environmental and social values of river water: examples from the Menik Ganga, Sri Lanka. AgEcon
Dissanayake, Priyanka; Smakhtin, Vladimir U..
Many decisions on water allocation in river basins are made on economic grounds. Environmental and social benefits of water should also be considered in river basin management, and attempts should be made to value them similarly. This is not a straightforward task and very few studies have directly addressed this issue to date. In this paper, the Menik Ganga (River) in southern Sri Lanka is used as a case study to attempt and evaluate the costs and benefits of environmental water allocations, referred to as ‘environmental flows’ (EF). In this study, a broad definition of EF is used: the components of EF evaluated include the requirements of the religious festival, the requirements of the Yala National Park, the requirements of the Pilinnawa Coastal Wetland...

Long-term ecological research in the forests of the United States: Key lessons for its application in Chile and around the world RChHN
FRANKLIN,JERRY F; SWANSON,MARK E.
Long-term ecological research addresses questions to which short-term research projects cannot effectively respond because of the temporal scales over which many ecosystem processes operate. In North America, this type of research has yielded important information on key processes and organisms in many forest types, from eastern broadleaf forests to the coniferous forests of the west, and from tropical to boreal latitudes. Long-term ecological research (that conducted at the decade scale or longer) in the forests of North America has included watershed studies, silvicultural trials, establishment of permanent plots to assess forest demographics, and the study of disturbance regimes and predator-prey systems. Instituting such research in forest ecosystems...

Setting population targets for mammals using body mass as a predictor of population persistence ArchiMer
Hilbers, Jelle P.; Santini, Luca; Visconti, Piero; Schipper, Aafke M.; Pinto, Cecilia; Rondinini, Carlo; Huijbregts, Mark A. J..
Conservation planning and biodiversity assessments need quantitative targets to optimize planning options and assess the adequacy of current species protection. However, targets aiming at persistence require population-specific data, which limits their use in favor of fixed and non-specific targets, likely leading to unequal distribution of conservation efforts among species. Here we propose a method to derive equitable population targets, which are quantitative targets of population size that ensure equal probabilities of persistence across a set of species, and can be easily inferred from species-specific traits. We applied population dynamics models across a range of life-history traits representative for mammals, and estimated minimum viable population...

Sustainable financing of protected areas in Cambodia: Phnom Aural and Phnom Samkos wildlife sanctuaries AgEcon
Grieg-Gran, Maryanne; de la Harpe, Derek; McGinley, John; MacGregor, James; Bond, Ivan.
In order to increase protected area revenue, and as part of a drive for national economic development, the Cambodian government is starting to issue economic concessions in 'sustainable development zones' of of protected areas. The Phnom Aural and Phnom Samkos wildlife sanctuaries cover nearly 600,000 ha and are important for biodiversity conservation and environmental services. They are home to about 30,000 people who rely on subsistence agriculture, cattle raising, and collection of non-timber forest products for their livelihoods. Under the Cardamom Mountains Wildlife Sanctuaries Project, a joint project of the Cambodian Ministry of Environment and Fauna and Flora International, zoning plans have been developed for both sanctuaries through participatory...

BREYER, F.R. dos S..
O jacare no Pantanal, e uma especie que ha quase uma decada vem sofrendo enorme pressao de caca clandestina, devido ao valor economico de seu couro e ao impedimento de sua utilizacao na forma de individuos adultos. O uso deste recurso natural necessita de legalizacao para tornar-se um complemento economico para as propriedades da regiao, hoje, exclusivamente sustentadas pela pecuaria. Atualmente, o manejo sustentado da especie, em condicoes naturais, e a forma mais viavel para sua explotacao racional. Baseia-se na coleta de ovos, sua incubacao e a manutencao dos filhotes em cativeiro. Um percentual dos filhotes nascidos, apos alcancarem um porte de mais de 60 cm de comprimento total, quando estao menos susceptiveis as predacoes naturais, serao repostos na...

The human health and conservation relevance of food taboos in northeastern Madagascar Ecology and Society
Golden, Christopher D.; Harvard School of Public Health, Department of Environmental Health; Wildlife Conservation Society, Wildlife Health and Health Policy, HEAL (Health & Ecosystems: Analysis of Linkages) Program; golden@hsph.harvard.edu; Comaroff, Jean; Harvard University, Departments of African and African American Studies and Anthropology; jeancomaroff@fas.harvard.edu.
Anthropologists and ecologists investigating the dialectical relationship between human environments and the cultural practices that shape and are shaped by them have been talking past each other for too long: the one looking purely at metaphor and the other purely at function. Our mixed-method data analysis set out to explore whether it was possible to determine empirically the human health and conservation value of the local Malagasy taboo system. This involved qualitative examination of the content of taboo origin stories collected through ethnographic approaches, when the story was remembered. The ethnographic substance of these stories included historicizing events, accounts of symptoms associated with breaching taboos, and incentives for abiding by...

Vertebrate road kill survey on a highway in southern Brazil Biological Sciences
Corrêa, Luiz Liberato Costa; Silva, Darliane Evangelho; Oliveira, Stefan Vilges de; Finger, Júlia Victória Grohmann; Santos, César Rodrigo dos; Petry, Maria Virginia.
 Highways are a major factor acting in the decline of several wildlife populations. Impact occurs due to the continuous flow of motor vehicles over tracks and collision with animals using the same area. This study aimed to list road killed wild vertebrates found in highways in the Pampa Biome, state of Rio Grande do Sul, over an entire year. The taxa found (amphibians, reptiles, birds and mammals) were identified to species level and their frequency of occurrence was seasonally registered. Along 2,160 km, we found 318 road killed individuals, totaling 65 species. This number represents an average of 0.147 road killed specimens by kilometer (that is, 1 individual each 7 km). Of these, seven species are under threat of extinction in the state of Rio Grande...
