Última Connectance of Brazilian social bee: food plant networks is influenced by habitat, but not by latitude, altitude or network size Biota Neotropica Biesmeijer,Jacobus C.; Slaa,E. Judith; Castro,Marina Siqueira de; Viana,Blandina Felipe; Kleinert,Astrid de M. P.; Imperatriz-Fonseca,Vera L.. Several recent studies suggest that the level of generalization (measured as percentage connectance) of plant-pollinator networks has several ecological correlates, e.g. latitude and altitude. Here we report on levels of generalization in 27 two-mode networks of social bees and their food plants in various Brazilian habitats and urban environments. Social bees are generalist foragers and are among the most abundant flower visitors in Brazil. They probably account for 30-50% of all plant - flower visitor interactions. Connectance was significantly influenced by habitat. Cerrado forests showed lower connectance than the dry dune habitats, with Atlantic rain forest and urban sites taking intermediate position and arid Caatinga being similar to dunes. This...

Ano: 2005 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1676-06032005000100010 Can climate shape flight activity patterns of Plebeia remota Hymenoptera, Apidae)? Iheringia, Sér. Zool. Hilário,Sergio D.; Ribeiro,Márcia de F.; Imperatriz-Fonseca,Vera L.. Flight activity of foragers of four colonies of Plebeia remota (Holmberg, 1903) was registered from December 1998 to December 1999, using an automated system (photocells and PLC system). The colonies originated from two different regions: Cunha, state of São Paulo, and Prudentópolis, state of Paraná, Brazil. Flight activity was influenced by different climatic factors in each season. In the summer, the intensity of the correlations between flight activity and climatic factors was smaller than in the other seasons. During the autumn and winter, solar radiation was the factor that most influenced flight activity, while in the spring, this activity was influenced mainly by temperature. Except in the summer, the various climatic factors similarly influenced...
