global demographic database project

Comparisons of population dynamics are a powerful approach to answering big questions in ecology, and are facilitated by the COMPADRE and COMADRE databases.

Work in our lab has shown that invasive species have higher projected population growth rates and greater vegetative reproduction than noninvasive relatives (Burns 2008). Also, differences in fecundity contribute more to invasiveness than differences in survival or growth (Burns et al. 2013).

Jean H. Burns is a member of the core committee for the COMPADRE & COMADRE database project to create an open-access database of matrix population models for both animals and plants from all over the world to facilitate its usage for scientific and teaching purposes.

These databases are a repository of demographic data from (mostly) published literature. As the number of published matrix population models (MPMs) grows, so do the opportunities to ask exciting questions about plant and animal demography, ecology, and evolution at a global and cross-taxonomic scale. The underlying motivation behind COMPADRE and COMADRE is to facilitate this research by collecting, digitizing, and archiving MPMs at a central repository in a standardized format.
