Variation in the local population dynamics of the shortâlived Opuntia macrorhiza (Cactaceae)
Spatiotemporal variation in demographic rates can have profound effects for population persistence, especially for dispersalâlimited species living in fragmented landscapes. Longâterm studies of plants in such habitats help with understanding the impacts of fragmentation on population persistence but such studies are rare. In this work, we reanalyzed demographic data from seven years of the shortâlived cactus Opuntia macrorhiza var. macrorhiza at five plots in Boulder, Colorado.
