Biodiversity, species interactions and ecological networks in a fragmented world
Biology and Immature Stages of the Bee Tribe Tetrapediini (Hymenoptera: Apidae)
The immatures of Coelioxoides and Tetrapedia are quite distinct from those of other known apids and by this study are quite different from one another based on features of the eggs, first instars, and pupae.

Comparing different methods for including interspecific interactions in distribution models for bees, their brood parasites, and the plants they pollinate shows that biotic interactions can be important in structuring species distributions at regional scales.

The understanding of bee communities and their association with particular habitats can prove to be a very useful tool in identifying the vulnerability of these organisms to landscape changes and is…
Nesting Biologies and Immature Stages of the Tapinotaspidine Bee Genera Monoeca and Lanthanomelissa and of Their Osirine Cleptoparasites Protosiris and Parepeolus (Hymenoptera: Apidae: Apinae)
Abstract The nesting biologies of Monoeca haemorrhoidalis (Smith) and Lanthanomelissa betinae Urban (Tapinotaspidini) are described from southeastern Brazil. Both are ground nesting; the nests of the…
[The use of different methods to sample the bee fauna (Hymenoptera: Apoidea), a study in the mixed temperate rainforest in Santa Catarina State].
A survey of the bee fauna of Araucaria Forest was performed in the border of a fragment in the district of Porto União, in Santa Catarina State, showing evidences of a seasonal pattern of activity of the bees and the importance of the use of complementary methods to survey the fauna.
Trap-nesting bees and wasps on the university campus in Sao Paulo, southeastern Brazil (Hymenoptera: Aculeata).

This paper reports the species of solitary bees and wasps nesting in wooden trap-nests on the campus of the University of Sao Paulo (23°33'S, 46°43'W), in southeastern Brazil, during three years…
Interactions at large spatial scale: The case of Centris bees and floral oil producing plants in South America
Bees, birds and yellow flowers: pollinator-dependent convergent evolution of UV patterns.
The hypothesis that flower colours and the visual capabilities of their efficient pollinators are adapted to each other is supported, and the appearance of UV patterns within flowers is the main difference in spectral reflectance between yellow bee- and bird-pollinated Flowers.
