Glaciation in the humid tropical Andes is a sensitive indicator of mean annual temperature. Here, we present sedimentological data from lakes beyond the glacial limit in the tropical Andes indicating that deglaciation from the Last Glacial Maximum led substantial warming at high northern latitudes. Deglaciation from glacial maximum positions at Lake Titicaca, Peru/Bolivia (16 degrees S), and La...

Itylos titicaca (Weyner 1890) has been reported to have a narrow distribution range associated with Andean wetlands called “bofedales” in Peru, Bolivia, northeast Chile and northwest Argentina.
