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... |

ABSTRACT Aiming to provide cardiovascular morphophysiology information on the Cuniculus paca, an important neotropical rodent, eight healthy adult females of this species were evaluated three times by echocardiography under general anesthesia with isoflurane every 15 days. The exams were performed by a single experienced evaluator with the animals positioned in right and left decubitus. Posteriorly, two expert evaluators measured the cardiac chambers, walls and flow patterns, by B-mode, M-mode, and Doppler ultrasonography. The resulting values were compared among evaluators and periods by the Bland-Altman agreement test and several descriptive statistics were presented for each parameter. Echocardiographic images were obtained between the second and fifth... |

Cholangiocarcinomas are neoplasms that originate from the bile duct epithelium. The present case described a cholangiocarcinoma in an adult female American Rhea (Rhea Americana araneipes) by means of gross, histopathology and immunohistochemistry. Irregular, firm, multifocal, yellow-white masses, measuring from 0.4 to 6cm in diameter were observed in both liver lobes. At the cut surface, multiple firm nodules filled with connective tissue were present. Microscopically, the neoplasia was composed of small, irregular, gland-like structures of neoplastic cells surrounded by connective tissue. The cells resembled epithelial cells of the hepatic biliary ducts. Neoplastic cells were positive for cytokeratin and negative for vimentin. This is the first report of... |

The aim of the current study was to evaluate the infection rate by Brucella spp. in wild and in captive animals. Serum samples from 121 animals (94 free-ranging and 27 captive) of different mammal species were evaluated. Sera were submitted to rose Bengal test (RBT) for screening and serum agglutination tests (SAT) and 2-mercaptoethanol test (2-ME) for confirmatory results. Nine animals (five free-ranging and four captive) tested positive in RBT, but negative in the confirmatory tests. Several domestic animal diseases that have control programs are not focused on wild reservoirs, such as brucellosis in Brazil. The study of new reservoirs in wildlife is essential to prevent emerging diseases. |

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. |

ABSTRACTMycobacterium avium subsp. paratuberculosis (Map) is the etiological agent of paratuberculosis. In Chile, information about Map isolation from both domestic ruminant and wildlife species has been accumulating, but it has to be extended to other species. The present study focuses specifically on one wild grazing species, the pudu (Pudu puda), one of the less known South American deer considered an endangered species that shares pastures with cattle in southern Chile, where the greatest part of the country's dairy cattle population is located. Convenient samples from 3 pudus were collected from one dairy farm where Map infection had previously been confirmed in cattle. All three pudus shed the bacterium in feces and the isolates are the same type of... |

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... |

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... |

Descreve-se o primeiro caso de paratuberculose em veado pudu-do-sul (Pudu pudu). O animal foi encontrado na cidade de Concepción, centro sul do Chile, em péssimas condições e com sinais claros de diarréia. Internamente apresentava séria atrofia de gordura no coração, lesões histológicas nos pulmões, fígado, baço e rins, e injúrias intestinais. Diferentes amostras foram preparadas com Ziehl-Neelsen, e os linfonodos mesentéricos presentes no íleo foram fortemente positivos para a bactéria resistente ao ácido. |

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... |

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... |

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... |
