Matrix Population Models for Population Management and Conservation

24-27 mars 2014
Centre d'Ecologie Fonctionnelle et Evolutive - Montpellier (France)

Population dynamics studies aim to understand variation in the size and structure of populations. This field forms a major component of both fundamental population biology, e.g. the evolution of demographic strategies, and applied population biology, e.g. understanding and predicting the impact of global change on populations. Population dynamics focuses on process rather than pattern. Individual performance, which is a function of variables such as age and breeding status, translates to population processes such as birth, death and dispersal. Demographic models map these processes, and their variation, through time, often with counter-intuitive results. This workshop will review the construction and analysis of matrix models. Matrix models describe population processes on a discrete time scale and for discrete classes of individuals, e.g. age classes, sites, or developmental stages. We will discuss deterministic models and their generalization to include environmental stochasticity, demographic stochasticity, uncertainty, density-dependence, and spatial structure. We will also explore the practical application of matrix models using parameter estimates obtained from field data. We will emphasize a bottom-up approach that views models as tools to answer questions and modeling as an “art of simplification”. The focus will be on the use of models to explore the conservation and management of both plant and animal populations.
