In this Feb. 19, 2019 photo, the bones of an animal lie on a rock during a scientific mission to study how temperatures and plant life are changing in the Andean ecosystem known as the paramos _ a mist-covered mountain grassland that lies between the top of the treeline and the bottom of the Humboldt glacier, in Merida, Venezuela. A team of scientists in Venezuela is trying to weather the political and economic crisis engulfing their country to record what happens as Venezuela's last glacier vanishes.
