DOIAbstract
Scotobius pilularius Germar 1823 (Tenebrioninae: Scotobiini) is mainly distributed in natural temperate and mesic grasslands of the Pampean biogeographic province. However, it is also found in climatically extreme environments such as cold and dry grasslands within the Patagonian biogeographic province. In these extreme environments, S. pilularius is found outside of natural habitats, in areas associated with human settlements. In the present paper, the role of climatic conditions and human settlements as determinants of the observed spatial distribution of S. pilularius in its natural distribution and outside that area is assessed. Three following hypotheses are tested: species occurrence is determined by i) climate; or ii) human settlemen...
