Abstract Lake Titicaca, in the High Andes of Perú and Bolivia, harbours world’s third most speciose ancient-lake amphipod radiation on record. A minimum nineteen species Hyalella derived from at least five independent colonization episodes concentrate this high altitude water body, although actual number present has not yet been established could be much higher. Herein, we take advantage descri...

An efficient one-way airflow system is essential for bird flight. Extracting more oxygen per breath than mammals, birds can meet the costly fuel demands of flight. However, despite the gains achieved by maximising the amount of oxygen passing through their lungs, the metabolic cost of breathing for birds could be high. Birds were thought to have to work against the weight of their flight muscle...

Located within the Altiplano at 3,686 m above sea level, Lake Poopó is remarkably shallow and very sensitive to hydrologic recharge. Progressive drying has been observed in the entire Titicaca-Poopó-Desaguadero-Salar de Coipasa (TPDS) system during the last decade, causing dramatic changes to Lake Poopó’s surface and its regional water supplies. Our research aims to improve understanding of Lak...

The data presented in this paper provide direct microbotanical evidence concerning the early use of potato (Solanum tuberosum) within its botanical locus of origin in the high south-central Andes. The data derive from Jiskairumoko, an early village site in the western Titicaca Basin dating to the Late Archaic to Early Formative periods (∼3,400 cal y BC to 1,600 cal y BC). Because the site refle...

Raised field agriculture is a pre-Hispanic intensive crop production system used in the Andean region of highland Peru and Bolivia around the Lake Titicaca Basin (Figure 6.1). The system combines the use of large raised earthen planting platforms with complex networks of intervening canals and ditches. These features are evidence of massive earthmoving and landscape modification covering an are...
