Although life histories arise at the intersection of ecological and evolutionary dynamics (Alonzo & Kindsvater, 2008), attempts to link life history to habitat and ecological contexts remain diffuse and lack a comprehensive theory after decades since the synthesis of Stearns (1997). Stearns (1997) Abstract Stingless bees are abundant and generally numerically dominant in bee communities in the tropics. Given that the collective foraging of their colonies is driven by communication systems, the preferential use and sharing of productive and spatio-temporally concentrated floral sources, are probably at the center of the foraging economy of the colonies of these bees. This study analyzed the influence of habitat anthropization on spatial variation in the survival of tropical stingless bee colonies. We investigated how three categories of habitats affect the survival of colonies within communities in a landscape of large fragments of disturbed natural forest and a matrix of rubber agroforestry. Random sampling of replicates of each habitat type for two years located 118 nests of 14 species in the two natural forest habitats and 105 nests of six species in the anthropic habitat. Monitoring revealed significant differences in colony survival between young and old-growth forests and between old-growth forests and anthropic habitats. The highest annual survival rates, ranging from 87% to 93%, were associated with three medium-large sized bee species that were most abundant and exclusive to the two forest habitats: Melipona scutellaris Latreille, 1811, Scaptotrigona xanthotricha Moure, 1950 and Scaptotrigona bipunctata (Lepeletier, 1836). These three species had similar survival rates in the two forest regeneration stages. Another species abundant in the landscape was Tetragonisca angustula (Latreille, 1811), a small habitat generalist with the lowest survival rate among the three habitats in the anthropic (43%). Euclidean distance analysis based on this habitat-generalist placed young forests closest to anthropic habitat and grouped the replicates of old-growth forest together. Considering the observed spatial variation, we infer that the Atlantic Forest favors stingless bees with high colonial longevity. In contrast, habitat-generalists, such as T. angustula, with small body sizes, short colonial longevity and high reproduction rates are favored by deforestation and replacement of forest with anthropogenic habitats.
