Etterson, M A. AND R S. Bennett. COST VS. QUALITY IN DEMOGRAPHIC MODELLING: WHEN IS A VITAL RATE GOOD ENOUGH? Presented at International Society for Ecological Modeling, Quebec City, Canada, August 22-24, 2004.
Description:
This presentation will focus on the assessment of quality for demographic parameters to be used in population-level risk assessment. Current population models can handle genetic, demographic, and environmental stochasticity, density dependence, and multiple stressors. However, current demographic data are at best, estimates of mean survival and fecundidty rates. For many taxa we lack even a rudimentary knowledge of dispersal that would allow us to predict immigration and emigration rates. The central question of this talk, then will be, "how can we begin to take advantage of sophisticated population models when our data remain rudimentary"?
