[email protected] Native bees contribute with a considerable portion of pollination services for endemic as well as economically important plant species. Their decline has been attributed to several human-derived influences including global warming as well as the reduction, alteration and loss of bees’ habitat. Moreover, together with human expansion comes along the introduction of exotic plant species with negative impacts over native ecosystems. Anthropic effects may have even a deeper impact on communities adapted to extreme environments, such as high elevation habitats, where abiotic stressors alone are a natural limitation to biodiversity. In these, human-borne alterations, such as the introduction of exotic plants and urbanization, may have a greater influence on native communities.
