Modelling fish spatial dynamics and local density-dependence relationships: detection of patterns at a global scale
TL;DR: In this article, a model is used to explore whether local density-dependent recruitment relationships can be observed when considering a larger scale, where a virtual population of spawners is tracked within an artificial environment composed of cells.

TL;DR: This work considers modelling and other applications, including the role of nearest neighbourhood in experimental design, the representation of connectivity in maps, and a new method for performing field surveys using hexagonal grids, which was demonstrated on montane heath vegetation.

TL;DR: This work presents the individual-based model Piscator, which describes a multi-species fish community and demonstrates techniques to deal with the inherent complexity of such a model, and proposes a novel procedure for calibration and analysis, in which the complexity of the model is increased step-by-step.

TL;DR: Two individual-based models for the movement of elvers in the French river ‘Adour’ are built and a set of stochastic differential equations and a partial differential equation for the elvers’ density are rigorously obtained.

TL;DR: If the migration rate is large enough and has density dependence of the correct form, then the steady state can be destabilised and the population size on each patch remains constant over time, hence the change might more properly be described as a decrease in homogeneity rather than in stability.

TL;DR: A dynamic model of a multiple species fishery that incorporates a community level phenomenon — community predation — indicates that predictable order, the basis of management control of these kinds of multiple species systems, may be found at the system rather than at the individual population level.

TL;DR: An individual-based model is presented which allows individuals to move several times per generation and hence allow them to reproduce at a site far removed from their position at the start of the generation, and it is shown that the behaviour of the model is largely unaffected by reducing the synchrony between migration events.

TL;DR: This work has unearthed interesting new phenomena which have been proposed as explanations for many long-standing ecological problems involving spatial movement and heterogeneity of species.
Abstract: With few exceptions, spatial heterogeneity in ecological models has been largely ignored until relatively recently. The current upsurge in interest is partly due to cross-fertilization with other disciplines, particularly mathematics. Models of species interaction in which the species disperse by diffusion are mathematically similar to those that arise in chemical reaction-diffusion systems which have been proposed as a basis for morphogenesis. Reaction/species interaction-diffusion systems have been increasingly studied mathematically in the last 15 years; this work has unearthed interesting new phenomena which have been proposed as explanations for many long-standing ecological problems involving spatial movement and heterogeneity of species. This is a very brief introduction to some of the basic results and how they impinge on ecology.
