Table 5.
Proportions of epiphytes with crassulacean acid metabolism (CAM) and C3 growing on the Annona glabra trees along the shoreline of Barro Colorado Island (BCI), Panama. About 50 % of the trees growing around BCI form the basis for a long-term study that encompasses three censuses: 1994, 2002 and 2015. Included here is a subset of 145 trees that were studied before and after a very strong El Niño event (Einzmann et al., 2022b)
