Reserva Los Cedros, Ecuador
Right now this is serving as a place for info on my dissertation research on the pollination biology of mushroom-mimicking Dracula orchids.
I have been posting some research related stuff on my travel blog.

Graduate student Tobias Policha has long had a dual love affair with plants and the open road. He satisfied both of these passions last spring and winter on a five-month stint in a remote cloud forest reserve in the Ecuadorian Andes, where he studied one of nature’s most fascinating cases of here to read the whole story.
