Spatially Explicit Population Models

چکیده
During the last decade, ecologists and particularly mathematical ecologists have focused on different approaches to the problem of spatial distribution of species. When the spatial distribution is not considered explicitly, the mathematical models are called spatially implicit. They consider the proportion of territory occupied by given species, but there is no information on which particular sites this occupation takes place (Caswell & Cohen, 1991; Barradas & Cohen, 1994; Barradas et al., 1996; Barradas & Canziani, 1997; Hanski, 1999; Federico & Canziani, 2000). When the spatial distribution of the species is specified, the models are called spatially explicit (Turner et all., 1995; Marquet & Velasco-Hernández, 1997; Hanski, 1999; Neubert & Caswell, 2000; Ruiz-Moreno et al., 2001).

Spatially Explicit Population Models: Current Forms and Future Uses
Spatially explicit population models are becoming increasingly useful tools for population ecologists, conservation biologists, and land managers. Models are spatially explicit when they combine a population simulator with a landscape map that describes the spatial distribution of landscape features. With this map, the locations of habitat patches, individuals, and other items of interest are e...
متن کاملUsefulness of Spatially Explicit Population Models in Land Management
Land managers need new tools, such as spatial models, to aid them in their decision-making processes because managing for biodiversity, water quality, or natural disturbance is challenging, and landscapes are complex and dynamic. Spatially explicit population models are helpful to managers because these models consider both specieshabitat relationships and the arrangement of habitats in space a...
متن کاملSpatially explicit Bayesian clustering models in population genetics.
This article reviews recent developments in Bayesian algorithms that explicitly include geographical information in the inference of population structure. Current models substantially differ in their prior distributions and background assumptions, falling into two broad categories: models with or without admixture. To aid users of this new generation of spatially explicit programs, we clarify t...

متن کاملChange Allocation in Spatially-Explicitly Models for Aedes Aegypti Population Dynamics
This work proposes a new approach to couple Aedes aegypti population dynamic models with local scale spatially-explicit computational models for the Geographical Space. A geographic database was developed for a neighborhood in Rio de Janeiro, RJ, and used to estimate the spatial pattern of mosquito infestation to estimate areas of epidemic risk.
متن کاملSpatially explicit maximum likelihood methods for capture-recapture studies.
Live-trapping capture-recapture studies of animal populations with fixed trap locations inevitably have a spatial component: animals close to traps are more likely to be caught than those far away. This is not addressed in conventional closed-population estimates of abundance and without the spatial component, rigorous estimates of density cannot be obtained. We propose new, flexible capture-re...
