Kingery-Page / The primary reasons for the existence of contemporary zoological parks are presented as conservation and conservation education. But in reality, human entertainment is the primary function of traditional zoos. There is a moral dilemma behind the practice of removing wild animals from their native habitats and holding them captive, primarily for the purpose of human entertainment and education. Exhibits designed with these human desires in mind never completely meet the needs of the animal. An exhibit designed with conservation in mind can fully address animal needs. The moral dilemma of keeping wild animals captive can be reconciled if the purpose of conservation shifts to the forefront of exhibit design. The term conservation, in this setting, refers to a habitat where a healthy, captive population can be sustained. Conservation means acquiring an in-depth understanding of an animal species and combining it with thoughtful, insightful design that responds to the species’ needs first. Secondary design considerations include facilitating the work of the animal keeper and visitor education and recreation. The keeper plays an important role in the health and well-being of the animal; a functional workplace is essential to the keeper’s job. The visitor plays an essential role in maintaining the funding that supports the zoo. In order for zoos to maintain adequate funding, they need visitors. To make this experience mutually worthwhile, exhibit design must create an experience that visitors want to be a part of, and the exhibit should impart an educational message to these visitors. This conservation-minded approach results in an exhibit that will serve primarily as a conservation facility. The exhibit is better suited to the animal by encouraging natural behavior and more accurately recreating natural habitat. A conservation exhibit can also fulfill the secondary purpose of human education by providing the visitor with a much richer depiction of the animal in its natural state, as well as showing visitors the need for species conservation.

Empirical measurements of the use of space of an enclosure are important indicators of the enclosure’s appropriateness for the exhibited animal. By studying the animal’s use of space zoological parks are able to provide a more species-adequate environment. In this study the utilization of space by the Siberian tigers held at Kolmården Djurpark was analyzed. Data were collected using the scan sample method for a total of 120 observation hours during 15 days. The tigers showed a marked difference in the utilization of different parts of the enclosure with the number of observations ranging from 1252 for the most popular zone to only 172 for the least popular one. The tigers showed a consistent preference for two of the 15 zones across all days of observation. Further analyses showed that these zones were preferred both during mornings and afternoons as well as during feeding days and non-feeding days. This study demonstrates that the tigers might display a preference for certain environmental features as a result of their behavioral needs that are no different from tigers in the wild.

This creative project investigated, planned and developed a master plan for the new National Zoological Botanical Park of Costa Rica. Based on an appraisal of the appropriate vegetation type for introduction onto a proposed study site, the flora and fauna from similar sites elsewhere in Costa Rica were identified. Placing the flora in the appropriate areas on the proposed study site allowed the fauna that has direct association with specific flora to be located. Based on slope analysis, contour formations, flora and fauna habitats, visitor and staff requirements, a master plan for the new National Zoological and Botanical Park of Costa Rica was developed. / Department of Landscape Architecture

Le virus Schmallenberg (SBV) appartient au genre Orthobunyavirus, au sein de la famille des Bunyaviridae. Ce nouveau virus, découvert en 2011 au nord-ouest de l’Europe, affecte les ruminants domestiques. Il est responsable de signes cliniques discrets chez les adultes et de malformations congénitales chez les nouveau-nés. Ces travaux de thèse s’inscrivent dans les projets d’étude de la pathogenèse de l’infection à SBV et de l’épidémiologie de la maladie, dans le cadre d’un programme de recherche européen sur le virus. Ce manuscrit inclut de nouvelles données, telles les cinétiques de la virémie et de la séroconversion chez les ovins et caprins, après infection expérimentale par SBV. La possibilité d’infection par SBV par voie vaginale est démontrée expérimentalement chez la chèvre. Après infection expérimentale de chèvres gestantes entre 28 et 42 jours de gestation, une mortalité fœtale ou des lésions du système nerveux central des fœtus peuvent survenir. Enfin, la sensibilité de plusieurs espèces de ruminants sauvages et exotiques de parcs zoologiques vis-à-vis de SBV est démontrée pour la première fois. / Schmallenberg virus (SBV) belongs to the genus Orthobunyavirus in the family Bunyaviridae. This new virus was discovered in 2011 in Northwestern Europe in domestic ruminants. Infection by SBV is associated with mild clinical signs in adult and congenital malformations in the progeny. In the scope of the European research program on SBV in the pathogenesis and epidemiology areas, the works included in this thesis provide new data about SBV infection in livestock and wild and exotic ruminants. The kinetics of viremia and seroconversion after experimental SBV infection are described in sheep and goats. This manuscript includes evidence of SBV infection via vaginal route in goats. Experimental SBV infection in pregnant goats between 28 and 42 days of gestation can lead to death or central nervous system lesions in fetuses. Evidence of susceptibility to SBV in several species of wild and exotic ruminants kept in zoos is described for the first time.
