Abstract:
I studied aspects of the ecology of the Murray River turtle, Emydura macquarii, to determine the impact of the introduced red fox, Vulpes vulpes. The fox is one of Australia's worst vertebrate pests through its predation on livestock and native mammals, but their impact on reptilian communities is not known. I conducted a large-scale mark-recapture study to evaluate population growth of E. macquarii in the Albury region of the upper Murray River by determining growth, reproduction and survival. The study was conducted downstream of the first, and largest, impoundment on the Murray River, La

Abstract:
Traditionally, differential-equation models for population dynamics have considered organisms as "fixed" entities in terms of their behaviour and characteristics. However, there have been many observations of adaptivity in organisms, both at the level of behaviour and as an evolutionary change of traits, in response to the environmental conditions. Taking such adaptiveness into account alters the qualitative dynamics of traditional models and is an important factor to be included, for example, when developing reliable model predictions under changing environmental conditions.

Ecosystems consist of complex dynamic interactions among species and the environment, the understanding of which has implications for predicting the environmental response to changes in climate and biodiversity.

We address the problem of the consistency between discrete and continuous models for density-dependent size-structured populations. Some earlier works have discussed the consistency of density independent age and size-structured models. Although the issue of consistency between these models has raised interest in recent years, it has not been discussed in depth, perhaps because of the non-linear nature of the equations involved. We construct a numerical scheme of the continuous model and show that the transition matrix of this scheme has the form of the standard discrete model. The constructio

The Raso lark is a Critically Endangered bird endemic to the islet of Raso, Cape Verde.

Matrix models are formulated to study the dynamics of the structured populations. We consider closed populations, that is, without migration, and populations with migration. The effects of specific patterns of migration, whether with constant or time-dependent terms, are explored within the context of how they manifest in model output, such as population size. Time functions, commonly known as relative sensitivities, are employed to rank the parameters of the models from most to least influential in the population size or abundance of individuals per group

Abstract:
Mathematical modeling of population dynamics can provide novel insight to the growth and dispersal patterns for a variety of species populations, and has become vital to the preservation of biodiversity on a global-scale. These growth and dispersal stages can be modeled using integrodifference equations that are discrete in time and continuous in space. Previous studies have identified metrics that can determine whether a given species will persist or go extinct under certain model parameters. However, a need for computational tools to compute these metrics has limited the scope and analysis w

Efficient management of epidemics is one of the primary motivations for computational modelling of disease dynamics.

In such situations the question is how should resources for disease control be deployed to ensure the efficient management of the epidemic.

Abstract:
This master thesis consists of integrating an advanced model for avascular tumour growth into a multiscale computational framework for cell-population dynamics. In order to demonstrate this framework, the authors of the framework developed a simple model for avascular tumour growth, governed by the Laplace equation and a set of rules relating to the oxygen concentration, that they integrated with the framework. The realisation of this model closely followed previously established growth patterns of tumour cells up until the last phase, where predictions by some authors say the volume of the tu

Abstract:
Predator-prey relationships are among the most common species interactions in nature. By consuming prey, predators influence the composition, structure and dynamics of populations, communities and ecosystems. Moreover, the effect of predators on prey extends beyond that of direct consumption. When prey detect the risk of predation, via predator kairomones, prey alarms cues or elevated encounter rates, they can induce an array of plastic traits aimed at decreasing predation mortality, but that also result in changes in reproductive output. Defence strategies also often include simultaneous chan
