The cumulative increase in the number of plant and animal studies using matrix population models highlights the current and future potential of these databases to address global ecological and evolutionary questions. The world map above shows the number of matrix population models and GPS coordinates of the study populations (when available) for the species in COMPADRE and COMADRE. Species data are added and released periodically, and in progress data can be found here. Plants, algae, and fungi are available in COMPADRE, and animals, bacteria, and viruses are available in COMADRE.
