Factors affecting fish distribution in coastal habitats of the British Virgin Islands

Gratwicke, Brian January 2004 (has links)
Few studies of tropical fish communities compare fish distributions across the full range of near-shore tropical marine habitats. As a result, our understanding of tropical marine fish communities is often biased towards habitats preferred by researchers. The distribution and habitat preferences of all 136 fish species occurring at 106 stations in three bays off Tortola in the British Virgin Islands were assessed. At a species level, habitat type was often the key factor influencing fish distribution. Of the 44 species occurring at more than 10 stations, 3 were sand specialists, 5 were strongly associated with mangroves, 7 were dependent on seagrass and algal beds and 14 were found only on the forereef. Eleven species were widely distributed both on the forereef and in bays, and 9 of them showed clear evidence of ontogenetic partitioning. The juveniles all preferred bay habitat types and moved onto the forereef as they approached sexual maturity. At a community level, five distinct fish assemblages were found. The assemblage types were classified according to their distribution: 1) forereef, 2) reef flat, 3) non-mangrove associated seagrass, 4) mangrove associated seagrass and 5) eutrophic areas. Forereef stations were the most species-rich with 24 species per station while eutrophic stations had the most depauperate communities with only 4 species per station. Variation in fish species richness at each station was largely explained by a simple habitat complexity index. It accounted for 70% of the variation in fish species richness and 21% of the variation in fish abundance. Rugosity and variety of growth forms were the most important predictors of species richness, but the height of the habitat architecture was the most useful predictor of fish abundance. Artificial reefs were constructed to test the effects of each habitat complexity variable experimentally. Increasing rugosity, variety of growth forms and percentage hard substrate increased the observed number of species but increasing the variety of hole-sizes, and height had no effect. The only complexity variable that had a significant effect on fish abundance was percentage hard substrate. In addition to the static substrate structure, long-spined sea urchins Diadema antillarum affected fish distribution because small fish shelter from predators in their spines. The urchins increase species richness and abundance in low complexity seagrass beds, but on artificial reefs, where shelter was not a limiting factor, the effect was less pronounced. Organic pollution is another factor that negatively affects the fish community by reducing fish species richness and abundance. Poor water quality often alters the natural habitat, confounding observations, but fish species richness was reduced in polluted areas even when artificial reefs were used as habitat controls. The applications of these findings to the management and conservation of fish in the British Virgin Islands are discussed.

Beitrag zum Bösartigen Katarrhalfieber bei Wiederkäuern in zoologischen Gärten / A contribution to malignant catarrhal fever in ruminants in zoological gardens

Matzat, Talena 03 February 2012 (has links) (PDF)
Bösartiges Katarrhalfieber ist eine unheilbare Virusinfektion bei Paarhufern, die wiederholt in zoologischen Gärten auftrat, ohne dass die erkrankten Fehlwirte Kontakt zu Reservoirwirten hatten. Die BKF-auslösenden Gammaherpesviren sind eng miteinander verwandt und werden von verschiedenen klinisch gesunden Reservoirwirten latent beherbergt und ausgeschieden. Einige dieser Reservoirwirte sind seit längerem bekannt, andere wurden erst kürzlich identifiziert und es wird vermutet, dass es noch weitere unerkannte Reservoirwirte für BKF-Viren gibt. Hervorzuheben ist, dass die Viren normalerweise eng an ihre Reservoirwirte gebunden sind. Es traten in letzter Zeit jedoch immer wieder Fälle auf, in denen auch Fehlwirte zwar infiziert waren, aber nicht erkrankten oder das Virus sogar ausschieden. Der Zusammenhang zwischen dem Verhalten der BKF-Viren bei Fehl- und Reservoirwirten und den ungeklärten BKF-Fällen in zoologischen Gärten wurde in der hier vorliegenden Studie näher untersucht. Es sollte herausgefunden werden, ob Wildwiederkäuer, die bisher nicht als Reservoirwirte für BKF-Viren galten, diese Viren ausscheiden und so möglicherweise für die oben erwähnten BKF-Fälle verantwortlich waren. / Malignant catarrhal fever (MCF) is an incurable infectious disease in even-toed ungulates, which occurred repeatedly in zoological gardens in Europe without any contact between known hosts and animals with clinical MCF. The causative agents are closely related viruses of the family gamma-herpesviridae, which are latently carried and shed by different clinically healthy ruminant species. Some of the hosts for MCF viruses have been known for many years, while others have been identified only recently. Yet, there are probably still more host species to be discovered. It has to be pointed out that generally MCF viruses are strictly associated with their hosts. However, it has been reported that known susceptible species were infected with MCF viruses without showing any signs of MCF, some of which even excreted the virus. This present study investigates the relationship between the behaviour of MCF viruses in hosts and susceptible species and the nebulous cases of MCF in zoological gardens. The goal was to determine whether wild ruminants, which are normally not known as hosts for MCF, shed these viruses and are possibly responsible for MCF cases mentioned above.

Elephant impact on the large tree component and its potential effect on selected fauna

Rode, Sieglinde Corny 10 1900 (has links)
The aim of the study was to determine the consequences of elephant (Loxodonta africana) impact on selected nesting sites of avian fauna and other species in the Associated Private Nature Reserves. The study also aimed at answering key questions on how the architecture of trees influence nest site suitability and what landscape features affect nest site location. Furthermore the type of impact that elephants have on specific nesting sites was determined and how this would affect the short term persistence of these trees. The facillitatory role of elephants was examined by looking at the type of impact that produces gum exudants as well as what gum is selected for by primates and whether primary branch breaking may lead to the creation of nesting sites for species such as the southern ground hornbill (Bucorvus leadbeateri). / Environmental Sciences / M.

Sediada na Fundação Parque Zoológico de São Paulo (FPZSP), essa mostra é direcionada para a manutenção e exposição da população de serpentes pertencente à Fundação. Contudo, o seu objetivo não se limita a apresentar ao público espécimes nativos e exóticos em um cenário "bonito" e, sim, construir um ambiente propício ao bem-estar dos animais, bem como a vivências que resultem na educação ambiental e no vínculo positivo do visitante com as serpentes. Dentro desse projeto expositivo abrangente, encontra-se o objeto de estudo: o processo de criação coletivo e multidisciplinar de ambientações realistas, fundadas na representação de um habitat selvagem, e destinadas à manutenção e exposição de um ser vivo. E considerando que a pesquisa está imersa em um contexto de interface entre áreas, abarcando a criação em artes visuais, bem como o universo dos zoológicos, optou-se por abordar e discutir esse mesmo objeto, a partir de um elemento que sempre se manteve como campo propício de englobar a criação, identificado como mediador de ambos os universos e constantes em todo o processo: a paisagem / Abstract: The research presented here seeks to understand, under the point of view of the Visual Arts, the creative process of exhibition venues belonging to the exhibition "O Caminho das Serpentes". Headquartered in the Zoological Park of São Paulo, this show is directed to the maintenance and exposure of the population of snakes belonging to the Foundation. However, its goal is not limited to present to the public native and exotic specimens in a "beautiful "scenario, and yes, build an environment favorable to the welfare of animals, as well as the experiences that result in environmental education and the positive bond of the visitor with snakes. Within this extensive exhibition project, is object of study: the processes of creating collectives and multidisciplinary realistic ambientations, based on the representation of a wildlife habitat and designed to the maintain and exposure of a living being. And considering that research is embedded in a context of interface between areas, encompassing the creation in visual arts as well as the world of zoos, it was decided to address and discuss the same subject, from an element that always kept as favorable field to encompass creation, identified as a mediator of both universes and constant throughout all process: the landscape / Mestrado / Artes Visuais / Mestra em Artes Visuais

La cour et les animaux sous les Bourbons / Animals and the court under the Bourbons

Pieragnoli, Joan 05 December 2015 (has links)
Les animaux eux-mêmes font l’objet du chapitre liminaire. Mais, en en tant que tels, ils intéressent moins la présente étude que la façon dont leur utilisation par l’homme a été associée à l’essor de la vie de cour. La relation homme-animal en milieu de cour est abordée dans la première partie, sous l’angle des formes architecturales, des structures administratives ainsi que du cadre juridique et social au sein desquels elle s’épanouit à la charnière des XVIe et XVIIe siècles (chapitres I à III). Le chapitre IV aborde un dernier aspect de la relation entre l’homme et les animaux en décrivant la finalité alimentaire des seconds. La deuxième partie étudie la participation des animaux à la dynamique de cour, au moment où, à partir du règne de Louis XIII, la curialisation s’accélère. Il s’agit d’abord de préciser le rôle des animaux dans l’élaboration de modèles culturels véhiculés par la propagande et le mécénat princiers (chapitres V et chapitre VI). À l’échelle interne, la façon dont le développement des équipages et la codification des chasses royales participent à la curialisation fait l’objet des chapitres VII et VIII. L’impact de la sédentarisation de la cour sur les populations animales et sur le développement de l’architecture zoologique constitue la matière de la troisième partie. Le chapitre IX est consacré à la Ménagerie de Versailles et le suivant à l’institutionnalisation du mécénat scientifique qui lui a été associé. Les chapitres XI et XII étudient la répartition sélective des animaux en fonction des résidences de la cour et son incidence sur l’organisation de l’espace. / This study does not focus in on animals as much as it questions the way they have been used by men and the part they played in the development of court life. In the first part, I address the relation between man and animal in the court context, from the standpoint of the architectural forms, administrative structures as well as the social and legal framework, in which the relation blossomed during the transition of 16th to the 17th century (chapter I to III). Chapter IV deals with yet another aspect of the man-animal relation, describing the use of the latter for alimentary purposes. The second part questions the animals’ participation in the court dynamics, at a point when, beginning with Louis XIII’s reign, courtization accelerated. My first concern was to give a detailed account of the animal’s role in the conception of the cultural models conveyed by propaganda and sponsorship originating from princes (chapter V and chapter VI). On the internal level, chapter VII and VIII describe the way the development of hunting crews and the codification of royal hunts participate in courtization. In the third part, I examine the impact of the court’s settlement on animal populations and the development of zoological architecture. Chapter IX describes the Ménagerie of Versailles, while the next one addresses the joint process of institutionalization of scientific patronage. Finally, in chapter XI and XII, I argue that the selective distribution of animals depending on the court residencies had an impact on spatial organization.

Panda a panda / Panda & panda

Kocmanová, Michaela January 2020 (has links)
This diploma thesis presents a project documentation for construction of a zoo pavilion with a restaurant. The structure has to be designed in compliance with regulations for buildings with almost zero energy consumption. Its construction site is located within the existing compound of Prague’s zoo on plot no. 1491/1. The pavilion is proposed to house giant pandas. The building has three floors- one underground and two above. It is covered by a flat green roof. In terms of circulation, the structure is composed from two parts. The first one is formed by premises for the pandas, including necessary facilities for their wellbeing and their breeding; and the second part is visitors’ part, including restaurant, gift shop and amenities. The building is enclosed by two exterior expositions for pandas which are connected with the interior exposition premises by two ramps- tunnels. There is a roof terrace adjacent to the restaurant for visitors to enjoy the view of pandas in their exterior grounds. The vertical structure of the pavilion for giant pandas is a combination of load bearing brick walls and cast-in-place concrete walls- the underground floor and the ground floor is formed by the cast-in-place concrete walls and the upper floor is formed by the brick walls made out of autoclaved aerated concrete blocks. The horizontal structures are formed by prestressed concreted floor panels or in the case of the upper floor by cast-in-place reinforced concrete slabs.

Analýza návštěvnosti Zoo Brno / Analysis of ZOO Brno Attendance

Stejskalová, Markéta January 2017 (has links)
The main aim of this diploma thesis is to analyse visitation of the zoological garden in Brno and to make recommendations which could result in higher values of visitation. The major causes of the fluctuation in visitation are found out and the econometric model is created. Due to this model, we can predict the future values of the reference indicator. In order to determine the interdependence between Zoo Brno attendance and the number of guests accommodated in the South Moravian Region, the econometrics model of South Moravia Region visitation was created too. Based on the analysis of external and internal environment, recommendations which could positively influence Zoo Brno attractiveness and number of its visitors are suggested. All used methods of analysis and creating model are presented in the theoretical part of this diploma thesis.

Zoo tady a tam. Výzkum chování návštěvníků v zoologické zahradě v Praze a Reykjavíku. / Zoo here and there: Observation of Visitor Behavior in the Prague and Reykjavík Zoos

Vysopal, Ondřej Věnek January 2013 (has links)
In my diploma thesis I deal with the perception of the modern zoological gardens by observing visitor behavior. The thesis captures the emergence of zoos in Europe in the late 18th and 19th century gardens and their role as a source of knowledge and as a representation of the relationship between man and animal. Based on the observations of visitors I present two European zoological gardens - Prague Zoo and Reykjavík Zoo & Family Park - as spaces reflecting a certain culture. Reykjavík as a place with a simple mission dedicated for the education of small children in several fields, not only in zoology, and Prague as a complex universe, a merge of several different places with different meanings, such as a place for education, relaxation, photographing, standing against the contemporary western critical theories of zoological gardens. Key words: Zoological gardens, visitors, animals, humans, culture, looking at animals, behavior of visitors, Reykjavík, Prague, Iceland
