the tropical dry forest (TDF) and its biodiversity. Epiphytic orchids, more exposed to the
atmosphere than the terrestrial biota, remain dependent on climatic variables, making them
particularly susceptible to climate change. We studied the spatial and temporal changes of a
focal group of 12 orchid species typical of the TDF in Colombia, and the future conservation …
