In the department of Puno, deforestation in the provinces of Sandia, Carabaya, and San Antonio de Putina is increasing, affecting vulnerable species like the Andean bear (Tremarctos ornatus). To determine the areas and habitats used by this bear in Ollachea (Carabaya) and identify the human activities influencing its presence, an assessment was conducted in October 2014, involving a survey of 17.80 km of trails and interviews. Thirty-eight GPS points with species records were identified, ranging from 2009 to 4086 masl, in transitional zones of montane forest-puna (50.00%), montane forest (21.00%), puna (15.80%), and intervened areas (13.20%). These points were located up to 0.72 km from water sources and 1.87 km from the forest. A preference for Eryngium weberbaueri as food was observed. In Ollachea, the Andean bear faces significant pressures due to various human activities. The Interoc...

El oso andino (Tremarctos ornatus) se distribuye en una gran variedad de hábitats y en un amplio rango altitudinal en los Andes de América del Sur, lo cual se encuentra relacionado a la disponibilidad de alimento. En el Perú consume una gran variedad de componentes, principalmente de especies botánicas (98.3%), siendo las más frecuentes las familias: Bromeliaceae, Arecaceae, Cyclanthaceae y Poaceae. Por otro lado, el efecto de las infecciones parasitarias sobre el oso andino podría afectar también la dinámica de sus poblaciones. En el análisis de las heces colectadas en dos áreas, se identificaron tres protozoos: Blastocystis sp., Cryptosporidium sp. y Giardia sp., y tres nemátodos: Strongyloides sp., una especie indeterminada de Ascarididae (Baylisascaris sp. o Toxocara sp.), y una especie indeterminada de Ancylostomatidae (Ancylostoma sp. o Uncinaria sp.). Otros factores que...
