Some believe that provision of private property rights in wildlife on private land can provide a powerful economic incentive for nature conservation because it enables property owners to market such wildlife or its attributes. If such marketing is profitable, private landholders will conserve the wildlife concerned and its required habitat. But land is not always most profitably used for exploitation of wildlife, and many economic values of wildlife (such as non-use economic values) cannot be marketed. The mobility of some wildlife (their fugitive nature) adds to the limitations of the private property approach. While some species may be conserved by this approach, it is suboptimal as a single policy approach to nature conservation. Nevertheless, it... |

ABSTRACT: Ticks are known worldwide for parasitizing a number of wild hosts. However, few studies have been conducted on ticks in zoos in Brazil. The objective of the present study was to collect, identify, and report the parasitic tick fauna found on wild Amazon animals received and attended at the Santarém Zoological Park from September 2004 to September 2013. In all, 56 animals, including 26 mammals and 30 reptiles, were sampled, from which 1172 ticks were collected and identified, comprising 862 adults, 284 nymphs, and 26 larvae. Nymphs of Amblyomma geayi on three-toed sloth (Bradypus tridactylus), adults of Amblyomma longirostre on black dwarf porcupine (Coendou nycthemera), and nymphs of Amblyomma naponense on southern tamandua (Tamandua... |

Valuing objects is a distinctive human trait. It is necessary for rational behaviour. Factors that are likely to influence valuations, the difficulties of getting agreements about valuations and the limited perspective of economics as a basis for valuation are discussed generally in this article. Attributes of Otago Peninsula that seem to be valuable and worth conserving are listed and discussed, taking into account possible conflicts in getting maximum value from these attributes. Particular attention is given to the economic value of conserving wildlife species on the Otago Peninsula. As a result of the presence of these species and their use for tourism, expenditure of over $100 million NZ is generated annually in the Dunedin regional economy (directly... |
