COMPADRE and COMADRE demographic databases
In collaboration with Rob Salguero-Gómez (University of Oxford) and Owen Jones (University of Southern Denmark), I am compiling and digitizing all available projection matrix models on plant and animal species. This includes demographic data from journal articles, white papers, and dissertation theses for over 850 plant species and over 1000 animal species. The completed databases will allow large-scale comparative demographic studies, such as examining whether extinction risk may be predicted based on species traits. In 2018, we received an NSF Advances in Biological Informatics grant to further develop the database infrastructure and improve our outreach and education efforts.
The first version of the COMPADRE Plant Matrix Database went online in November 2014, and the first version of the COMADRE Animal Matrix Database was released in October 2015. Please check it out!

Frasera speciosa & data requirements for demographic studies
Frasera speciosa (Gentianaceae) is a long-lived, monocarpic plant with mast seeding, a type of plant whose demography is rarely studied. I analyzed a 35-year dataset to describe its population dynamics using matrix projection models. The unusual length of the dataset also allowed me to examine how many years of data are needed to obtain consistent estimates of the long-term population growth rate and other population parameters.
Matrix data from this study have been archived in the Ecological Society of America's Data Registry and are available upon request.
