Dynamical behavior of a stage structured prey-predator model
In this paper, a new stage structured prey-predator model with linear functional response is proposed and studied. The stages for prey have been considered. The proposed mathematical model consists of three nonlinear ordinary differential equations to describe the interaction among juvenile prey, adult prey and predator populations. The model is analyzed by using linear stability analysis to ob...
متن کاملSpatially-explicit matrix models. A mathematical analysis of stage-structured integrodifference equations.
This paper is concerned with mathematical analysis of the 'critical domain-size' problem for structured populations. Space is introduced explicitly into matrix models for stage-structured populations. Movement of individuals is described by means of a dispersal kernel. The mathematical analysis investigates conditions for existence, stability and uniqueness of equilibrium solutions as well as s...
متن کاملOn Parallelization of a Spatially-Explicit Structured Ecological Model for Integrated Ecosystem Simulation
Spatially explicit landscape population models are widely used to analyze the dynamics of an ecological species over a realistic landscape. These models may be data intensive applications when they include the age and size structure of the species in conjunction with spatial information coming from a geographic information system (GIS). We report on parallelization of a spatially explicit lands...
متن کاملA length-structured spatially explicit model for estimating hake growth and migration rates
Despite an abundant literature, hake growth and migration remain poorly understood. A recent tagging campaign and an analysis of the growth increments on juvenile hake otoliths demonstrate that the growth rate has probably been largely underestimated. Migration rates have been studied through qualitative analysis of catch rate, but have not been confirmed by a more-quantitative analysis. Those ...
متن کاملSpatially Explicit Model of Deforestation in Bolivia
A GIS compiled by the Departmental Government of Santa Cruz, Bolivia offers data that may help to resolve some competing theories of tropical deforestation. The GIS contains many attributes relating to land use at two points in time, 1989 and 1994, and allow us to address questions like: • What has been the impact of past road construction on deforestation and land use? • What impacts might be ...
