Background Recent declines in bee populations, along with increasing demand for
pollination services in urban, agricultural, and natural environments, have led to strategies to …

Bee pollinators are currently recorded with many different sampling methods. However, the
relative performances of these methods have not been systematically evaluated and …

Climate conditions tend to differ along an altitudinal gradient, resulting in some species
groups' patterns of lower species richness with increasing altitude. While this pattern is well …

Pollination is an important ecosystem service, especially to self-sterile crops as passion fruit,
which depends on the large solitary bee for fruit set. We estimated the species richness of …

Solitary cavity-nesting bees, especially trap-nesting Megachilidae, have great potential as
commercial pollinators. A few species have been developed for crop pollination, but the …

We studied the community ecology of trap-nesting bees in two forest fragments of the State
of São Paulo, Brazil, during two years, utilizing bamboo canes and tubes made of black …

Cavity-nesting bees and wasps (Hymenoptera: Aculeata) have been showed to be suitable
models to investigate the effects of forest fragmentation and human land use. Those studies …

Worldwide distributed tropical savannas were established only in the Miocene, with climatic
cooling and rise of C4 grasses. However, there is evidence for an earlier presence of …

Cavity-nesting bees are enigmatic because they are difficult to observe in the wild, hence
trap-nests (man-made cavities) provide the means by which these bees may be studied …

We investigated changes in the communities of trap-nesting Hymenoptera in forests in
relation to forest loss on a landscape scale and understory conditions on a local habitat …
