Structure of bee-flower system in the coastal sand dune of Abaeté, northeastern Brazil Rev. Bras. entomol.
Viana,Blandina F.; Kleinert,Astrid M. P..
For twelve months (from January to December of 1996) we investigated bee-flower interactions in a sea coastal ecosystem in Bahia, Brazil. Samples were taken three times each month. 3983 individuals belonging to 49 bee species, grouped in 13 morph-functional categories, visited 66 plant species belonging to 39 botanic families. It was observed 310 interactions between bees and plants at species level. The use of floral resources by bees was not homogeneous; most of the plant species received a low number of visitors. No restricted plant-bee species relationship in resource use concerning the subset of analyzed interactions was detected. In Abaeté the generalist relationships predominated.

Positive relationship between soil fertility, plant diversity, and gall richness Biological Sciences
Melo Júnior, João Carlos Ferreira; Boeger, Maria Regina Torres; Isaias, Rosy Mary dos Santos; Arriola, Igor Abba; Lorenzi, Luciano; Mouga, Denise Monique Dubet da Silva; Vieira, Celso Voos.
The complexity of nutrient distribution patterns in soils is a determinant environmental component of the structure of plant communities. Numerous insect species that interact with plants are associated with these communities, and some of these interactions result in the formation of unusual structures called galls. In this study, we investigated the relationship of galls, soil fertility and plant communities in three vegetation types, herbaceous restinga (HR), shrub restinga (SR) and shrub-tree restinga (STR), in an area of restinga in southern Brazil. We identified 217 species belonging to 159 genera and 82 families. The plant diversity recorded in the STR was 42.8% higher than the diversity in the other vegetation types. Gall richness increased...
