Mathematical and computational approaches to contagion dynamics on networks
… to the temporal setting. Next, we present a meta-population model for the spread of COVID-19 in Ireland which makes use of temporal commuting patters generated from the radiation model. Finally, we analyse a year worth of Irish cattle trade data. We then fit a number of mobility models and …

Allee effects and the persistence of small populations
… in the establishment success of insect pest populations during the early phases of invasion. Secondly, to examine how spatial management at the point of introduction could render populations more vulnerable to the Allee effect and facilitate their eradication. Both aims are important, as …

The Impact of Habitat Alteration on the Population Dynamics of a Declining Woodland Bird in the Mount Lofty Ranges
… declines. This thesis examined an isolated meta-population in the Mount Lofty Ranges (MLR), South Australia, subsisting in heavily degraded grassy woodland dominated by exotic annual grasses. The hypothesis that changes in grass seed phenology associated with invasion by exotic annual …

Behavioral syndromes and their effect on dispersal in Notonecta irrorata
… animal personality as a legitimate factor in population and meta-population dynamics.

IMPACT OF CLIMATE CHANGE ON WILDLAND FIRE THREAT TO THE AMUR TIGER AND ITS HABITAT
… poses a limited threat to the Amur tiger meta-population. The observed peaks in high fire threat conditions are localized in space and time and are likely to impact a small number of individual tigers. Under the wide range of the IPCC climate change scenarios, no considerable change in …

The use of ringing data in the study of climatic influences on common passerines
… wintering grounds, and during migration. In a population of African Reed Warblers Acrocephalus baeticatus (an azonal wetland specialist) a capture-mark-recapture model correlated higher temperature in the breeding grounds with higher adult survival (1998-2010), but - contrary to expectations - …

Mathematical Models of Ebola Virus Disease and Vaccine Preventable Diseases
… of vaccine preventable diseases. A three-patch meta-population model is developed that incorporates spatially explicit migration of individuals. The model is used to evaluate vaccination strategies to mitigate outbreaks. It suggests that rural-urban migration is an important factor in designing …

Understanding spatial structuring and the role of domestication in the development of sustainable harvest techniques of Mopane worms (Gonimbrasia belina).
… indigenous edible insect that periodically has population eruptions in Mopane tree (Colosphermum mopane) dominated vegetation. This insect is a valuable source of food and has become an economic commodity for commercial harvesters. Despite its importance, little is known of the population …

MODELING AND MINING ANTIMICROBIAL RESISTANCE IN HUMAN AND ANIMAL POPULATIONS
… spread of resistant bacteria in human and animal populations. Resistant bacteria and resistance genes spread between individuals through direct and indirect pathways, such that antimicrobial use in one population can result in increased morbidity and mortality from resistant bacteria in another …

Novel Applications of Geospatial Analysis in the Modeling of Infectious Diseases
… demonstrate the usefulness of such data in a meta-population patch model meant to forecast the spread of Ebola in the Democratic Republic of Congo. In Chapter 4, we also demonstrate that mobility data can be used to strengthen outbreak detection via hotspot analysis, and to augment incidence …

Parentage analysis in a free-ranging, closed population of southern white rhinoceros : genetics, pedigrees and management
Small populations of animals are vulnerable to the consequences of breeding within a closed group – inbreeding depression and genetic drift lead to reductions in genetic variability, which in turn can give rise to the amplification of deleterious traits. Traditionally, managers attempt to minimise …
