Abstract

ROSSI, Christian et al. First study of the coleopterans richness of Polylepis tomentella from Chaviña district (Ayacucho, Perú). Ecol. austral [online]. 2018, vol.28, n.1, suppl.1, pp.229-234. ISSN 1667-782X.

Polylepis woodlands are vulnerable ecosystems that are under strong anthropogenic pressure. These woodlands are fragmented, forming patches on the slopes of high andean and rocky mountains, where we find Polylepis tomentella. They are distributed in the departments of Ayacucho, Apurimac and Arequipa. In 2010, we evaluated the community structure of the order Coleoptera in a representative patch of the Chaviña district. Two surveys (wet and dry season) were carried out. Ten sampling stations were established and pitfall traps, bait traps, chromotropic traps, active collection and Malaise traps were used. Forty-five species were identified and distributed in 18 families, being Curculionidae and Carabidae the most representative. Estimated richness was between 43 and 47 species. The best richness estimator was ACE. These data can be useful for subsequent diversity studies and also to estimate the degree of disturbance of these woodlands.
