Geri Winkler
In the 1990s he ascended Popocatepetl in Mexico and Muztagh Ata (7546 m) in China. In the summer of 2001, he climbed Elbrus in Russia, the highest mountain in Europe. In the winter of 2002 and 2003, Winkler climbed Aconcagua in Argentina, the tallest mountain in South America.
Opiliones
Several Opiliones in Argentina appear to be vulnerable, if not endangered. These include "Pachyloidellus fulvigranulatus", which is found only on top of Cerro Uritorco, the highest peak in the Sierras Chicas chain (provincia de Cordoba) and "Pachyloides borellii" is in rainforest patches in northwest Argentina which are in an area being dramatically destroyed by humans. The cave-living "Picunchenops spelaeus" is apparently endangered through human action. So far, no harvestman has been included in any kind of a Red List in Argentina, so they receive no protection.
