New-generation individual based models for infectious diseases transmission
… and international scale. In this context, Individual-Based simulation Models (IBM) have become one of the much relevant approaches. The crucial point of this thesis project is to override some of the limit of the current generation of IBM. Specifically, highly detailed models of the …

Predicting Northern Goshawk Dynamics Using an Individual-based Spatial Model
… population size, and population viability. An individual-based spatial model was created for the Black Hills goshawk population. This project focused on evaluating our current understanding of goshawk dynamics, and making individual- and population-level predictions as appropriate following …

Modelling the evolution of warning signals and mimicry with individual-based simulations
Individual-based evolutionary simulation models are used alongside mathematical approaches as tools for investigating the selective pressures responsible for the origin and maintenance of animal warning displays and mimicry. The early chapters of the thesis review the literature on evolution and …

A first approach to individual-based modeling of the bacterial conjugation dynamics
This work presents a spatially explicit individual-based model of bacterial conjugation using use a discrete representation of time and space. The space is defined by a discrete grid where agents are place and evolve through their local interactions. Each agent is described by a state vector …

Individual-based modeling of white-tailed deer (Odocoileus virginianus) movements and epizootiology
… and predicting effects on host populations. Individual-based modeling (IBM) has become more commonplace in ecology as a tool to link individual behavior to population dynamics and community interactions, especially for gauging the effects of management actions. Spatially explicit IBMs are …

Examining Movement Dynamics of the Gulf Menhaden Fishery Using an Individual-based Model
… These analyses were used to inform an individual-based model (IBM). The IBM was run under several different spatial restriction regimes, including (1) current regulations in Texas, Louisiana, Mississippi, and Alabama; (2) additional restrictions off the coast of Jackson County, MS; (3) …

Issue of scale in individual-based models: applications in fungal and plant systems
… theoretical approach, in the form o f an individual-based (cellular automaton) model, is presented. Experimental results derived from small-scale systems are used to quantify parameters of the model; results from large-scale experimental systems serve to test the model. The theoretical …

An Individual-Based Model of Fish Habitat Selection for Network-Scale Watershed Assessment
The results of this research show that process-based interdisciplinary models can be developed for understanding large-scale ecological dynamics in river networks. The explicit inclusion of species' biological functions allows the model to explain the arrangement and response of stream communities. …

Ecological variability in coastal oceans : simulating biological-physical interactions with Lagrangian Individual-based models
In dieser Dissertation wird der Effekt biologisch-physikalischer Interaktionen auf zwei fundamentale Prozesse in küstennahen Ökosystemen mit Hilfe Individuenbasierter Modelle untersucht. Die Dynamik der Phytoplankton Frühjahrsblüte wurde in zwei aufeinanderfolgenden Jahren auf einem …

Linking individual-based models and dynamic energy budget theory : lessons for ecology and ecotoxicology
… of ecological risk assessment of chemicals, individual-based population models hold great potential to increase the ecological realism of current regulatory risk assessment procedures. However, developing and parameterizing such models is time-consuming and often ad hoc. Using standardized, …

Predicting the effect of environmental change on wading birds: insights from individual-based models.
… changes. This thesis looks into how we can use individual-based models (IBM) to make accurate predictions of how wading birds are affected by environmental change. Starting with previously validated models I show the importance of measuring size of invertebrates though an IBM investigation into …

Modelling animal movement in heterogeneous environments: from statistical inferential models to individual-based models
… state, motion, and navigation capacities of the individual and the external factors). I investigated the influences of environmental factors on movement by categorising them into two general classes: environmental stimuli perceived and responded to by animals, and environmental forces such as …

An individual-based GPU simulation framework for collective bacterial dynamics in swarms and biofilms
… rich experimental data sets, we develop minimal individual-based models to uncover the governing forces driving the dynamics in microbial systems. Our model incorporates the biophysical processes of cell growth and division, viscous drag, bacteria self-propulsion, and mechanical cell-surface and …

Conservation by simulation: an individual-based spatially explicit model to simulate population dynamics in fragmented habitat
… a model combining a population simulator based on individual behaviour, with a spatially explicit representation of a landscape. To investigate the robustness of the technique, representatives of three major taxa were modelled: the nuthatch (Sitta europaea L.), the white-footed mouse …

A comparison of individual-based and matrix projection models to applied to fish population and community dynamics
Matrix projection models and individual-based models (IBM) are commonly used for the analysis and management of fish populations. Matrix models break down the population into age or stage classes, while IBMs track individuals. I perform a series of quantitative comparisons between the predictions …

An individual-based modelling approach to examine life history strategies of sardine Sardinops sagax in the southern Benguela ecosystem
… southern Benguela ecosystem are tested using an individual-based Lagrangian particle tracking model linked with a 3-D hydrodynamic model of the region. Experiments focus on the dispersion of eggs and larvae among possible spawning and nursery areas. The two main areas of interest were the west …
