"When you find the frogs, when you work for them, when you realize you are doing something good for them, you feel good," he said.To encourage thoughtful and respectful conversations, first and last names will appear with each submission to CBC/Radio-Canada's online communities (except in children and youth-oriented communities). Reproduction is dioecious. Unlike many other poison dart frogs, this one contains histrionicotoxin, a deadly cardiotoxin only found in the harlequin poison dart frog.The symptoms include heart palpitations, physical weakness, and blurred vision, and in some cases cardiac paralysis leading to death. "I completely believe that in order to conserve this species you have to have the participation of the people living there," he said.Columbian universities are now providing funding for local people to develop ecotourism as an alternative source of income that discourages illegal trafficking, he added.There are also efforts to encourage the government to purchase land where there is important frog habitat.As a specialist in genetics, Posso-Terranova brings his knowledge and experience back to Saskatchewan to share with students in Saskatoon.He is an instructor and lab co-ordinator at the University of Saskatchewan, where his desk is surrounded by toy frogs and frog paintings drawn by school children he has presented to.Posso-Terranova said hiking the Colombian jungles for the vulnerable creatures can be draining — until he finds them.
