Abstract:

Dogs have a long but neglected history as companion species in Egypt history. From the most valued companion in ancient Egypt the relationship between dogs and humans has changed over time. However, in the present day the Egyptian baladi dog has been abused, neglected, unwanted for centuries. In this thesis, I investigate the nature and relationships between humans and dogs in Egypt in the past and present drawing on archeological, historical and genetic information. I will dig deeper into dog genetics to better understand the distinction between the baladi dog in relation to other breeds. Usi

Abstract:

Raccoon dogs (Nyctereutes procyonoides viverrinus Temminck) were used as a model species to study wildlife management and conservation issues in the countryside of Japan. Radio-tracking data were used to analyse habitat use, movements, home range configuration and stability, social aspects, and factors influencing raccoon dog behaviour. Comparisons were drawn with European badgers (Meles meles Linnaeus) in the UK in order to highlight aspects of movements and habitat use of omnivorous Carnivores. Two key issues concerning the conservation of raccoon dogs in Japan were investigated: road-kills

Abstract:

In the Great Plains, sylvatic plague (Yersinia pestis), poisoning, and habitat conversion continue to reduce and fragment black-tailed prairie dog (Cynomys ludovicianus) habitat in which burrowing owls (Athene cunicularia) seek shelter and nest sites. Consequently, burrowing owls are experiencing population declines at the periphery of their range. The objective of this research was to evaluate habitat factors affecting a population of burrowing owls at the eastern extent of their range. I modeled hypothesized relationships between nest density (Chapter 2) and colony productivity (Chapter 3) a

Abstract:

Bumblebees have undergone dramatic declines both in Britain and further afield during the last century. Bumblebees provide a crucial pollination service to both crops and wild flowers. For these reasons, they have received a great deal of research attention over the years. However, the ecology of wild bumblebee nests and the interactions between nests and other species, particularly vertebrates has been somewhat understudied. This is largely due to the difficulty in finding sufficient nests for well replicated study and a lack of appropriate methods of observation. Here, methods for locating b

Abstract:

Invasive plant species are an increasing global threat to native biodiversity. Effective management depends on accurate predictions of their spread. However, modelling the geographic distribution of invasive species, particularly with methods like correlative species distribution models (SDMs), is challenging. SDMs operate under the assumption that species are in equilibrium with their environment (i.e., they occur in all suitable environments); this assumption is more likely to be violated for a species that is still in the process of colonizing suitable environments. SDMs also assume that en

Gonarezhou National Park (GNP) and Savè Valley Conservancy (SVC) that hold part of the few remaining viable populations report that wild dog populations continue to decline due to high rates of habitat loss and fragmentation. This leads to low pup survival rates due to predators and reduced formation of new packs as the wild dogs have become reluctant to leave the safety of their original packs in pursuit of mating partners in fragmented habitats

Abstract:

Livestock guardian dogs – or “LGDs” – are commonly used by domestic sheep ranchers and reduce the need for killing wild carnivores to protect livestock. LGDs are mostly used in the United States to reduce the number of livestock killed by coyotes, but whether they can prevent killing by larger carnivores like wolves and grizzly bears is unclear. It is important to identify which behavioral traits and LGD breeds work best for guarding livestock so that ranchers can protect their stock and environmentalists can enjoy a greater number of wild animals on the landscape.

Shamwari Game Reserve was the first enclosed conservation area in the Eastern Cape Province of South Africa to reintroduce free ranging lions, cheetahs, leopards and wild dogs back into their historic range. At that time (2000 – 2001), little information was available on the ecology and behaviour of these predators in the habitats of the Eastern Cape, and management decisions were based on assumptions and unfounded comparisons with extant populations but from quite different habitats. The aim of this study was therefore to obtain a better understanding of the feeding ecology and space use of t

During the past few decades, examinations of social, biological, and communication networks have taken on increased attention.

Habitat loss and fragmentation and human-wildlife conflicts, often resulting in retaliatory killing in response to livestock predation, are one of the main threats to wild felids worldwide, including pumas (Puma concolor).

<p>The climate change is expected to affect especially alpine areas negatively, replacing the alpine flora with subalpine forest. The understanding of how vegetation influences total organic carbon (TOC) in soil, streams and lakes in alpine and subalpine areas will lead to a better understanding of the effects of climate change, and will also increase the knowledge of the ecotone as a whole. In this study plant-soil relations were examined in a subalpine and an alpine catchment in the north of Sweden, by comparing dissolved organic carbon (DOC) concentrations, 13C-DOC, 13 compared with lake an

Abstract:

Dogs are one of the most widespread carnivore and the third most invasive mammal, after cats and rodents. Stray dogs affect wildlife negatively by predation, disturbance, disease spreading, competition and hybridization with other wild canids. Even in urban environments stray dogs cause problems such as disturbance, pollution, traffic accidents, bites and risk of disease spreading. Serbia is one of many countries in the Balkan region that has a problem with overpopulation of stray dogs. The aim of this study is to investigate the population dynamics of stray dogs in Bor, Serbia and discuss dif

Abstract:

Juvenile trout were found predominantly in the tributaries while older trout and juvenile salmon were found predominantly in the main river. Localised reductions in juvenile salmonid abundance in relation to the degradation of the stream habitat were demonstrated. HABSCORE habitat evaluation models appeared to be reasonably accurate in predicting juvenile salmonid numbers. The recruitment of juvenile trout from a tributary into the main river during spring was assessed by trapping. Predictive models based on environmental parameters accounted for 64% and 78% of the variation in the timing of m

Abstract:

This research combines observation, experimentation, and modeling to evaluate the influence of lakes on dissolved organic matter (DOM) quantity, quality and export in subalpine watersheds of the Sawtooth Mountain Lake District, central Idaho. First, I conducted an empirical study of the hydrologic and biogeochemical controls on DOM dynamics in stream-lake fluvial networks. I hypothesized that lakes would decrease temporal variability (i.e., buffer) and alter the characteristics of DOM from inflow to outflow. I tested these hypotheses by evaluating DOM temporal patterns and measuring annual

Abstract:

O reservatório da Usina Hidroelétrica de Furnas - MG é um sistema com grande heterogeneidade e ecologicamente instável. Ele vem sofrendo com a degradação ambiental devido às ações antrópicas ao seu entorno, que lançam grandes volumes de matéria orgânica e inorgânica sob a forma dissolvida ou particulada. Nos últimos anos, o reservatório está com baixo volume útil o que associado as ações antrópicas pode afetar os processos ecológicos e alterar a comunidade zooplanctônica deste ecossistema.
