Résumé :

Humans are dependent on the animals they raise and breed for food and secondary products. Archaeological and genetic investigations can provide critical insights into the history and development of these breeds and help understand human activities in the past. Furthermore, many well-adapted breeds are endangered and archaeological and genetic data can help inform future breed conservation choices. Utilising ancient DNA data could potentially permit detailed diachronic analyses of the development of animal breeds. Ancient DNA analyses have typically focussed on large-scale biogeographic pattern

Résumé :

Biological management of populations plays an indispensable role in all areas of population biology. In deciding between possible management options, one of the most important pieces of information required by population managers is the likely population status under possible management actions. Population dynamic models are the basic tool used in deriving this information. These models elucidate the complex processes underlying the population dynamics, and address the possible consequences/merits of management actions. These models are needed to guide the population towards desired/chosen man

Résumé :

Animal population densities are thought to be "regulated" by density-dependent processes (Haldane, 1953; Royama, 1977: Berryman, 1991). The perceived importance of these processes to biologists is evident from the vast amount of research dedicated to this idea (Inchausti, 1994). Most of this research addresses the problem(s) of detecting the effect of density-dependent regulatory processes using time series data. However, the question of the relative importance of density-dependent factors upon rates of change of population abundances is rarely addressed. In this thesis, I quantify the importa

Résumé :

Animal breeding theory is based on the assumption that traits are controlled by many genes each having small effect, however, genes with a large effect have been identified in favourable circumstances. Where major genes can be identified, and individual animals genotyped, exploitation of the genetic variation can be optimised. Segregation analysis has been proposed as a suitable method for detecting major genes. It involves maximising and comparing the likelihood of the data under different genetic models to ascertain the most likely genetic structure. To identify a major gene the likelihood o

Captive populations have been established for most of these species, but successful management has proved challenging.

In this study, I examined the captive environment to identify the factors associated with reproduction, mortality, and health of rhinos and tapirs.

Texte intégral

Résumé :

A defining feature of capture-recapture is missing data due to imperfect detection of individuals. The standard approach used to deal with the missing data is to integrate (or sum) over all the possible unknown values. The missing data is completely removed and the resulting likelihood is in terms of the observed data. The problem with this approach is that often biologically unnatural parameters are chosen to make the integration (summation) tractable. A related consequence is that latent variables of interest, such as the population size and the number of births are only available as derived

Résumé :

Habitat fragmentation is a fundamental process that determines trends and patterns of distribution and density of organisms. These patterns and trends have been the focus of numerous terrestrial and marine studies and have led to the development of several explanatory hypotheses. Systems and organisms are dynamic and no single hypothesis has adequately accounted for these observed trends. It is therefore important to understand the interaction of these processes and patterns to explain the mechanisms controlling population dynamics. The main aim of this thesis was to test the effect of patch s

Staphylococcus aureus is a major opportunistic pathogen causing a wide range of infections in humans and animals.

All this changed in 2005 with the isolation of a specific MRSA clone, assigned to Clonal Complex (CC)398, from pigs and pig farmers in the Netherlands. These findings triggered worldwide investigation, showing the presence of this livestock-associated (LA)-MRSA clone in a variety

The herd-level incidence of Mycobacterium bovis has been increasing in the United Kingdom (UK) and Republic or Ireland (RoI) for the past thirty years, resulting in substantial economic and animal welfare issues. Failure to control this pathogen in cattle is in part due to European badgers (Meles meles), a wildlife reservoir that are responsible for a proportion of transmission of M. bovis to cattle.
