Orchid bee fauna responds to habitat complexity on a savanna area (Cerrado) in Brazil.
Sociobiology, 2016 Habitat structure and complexity may broadly affect the diversity and composition of a variety of fauna in terrestrial systems. Here we investigated responses of orchid bee assemblages to habitat complexity, with the aim of assessing complexity as a ...

Experimental investigation of the effect of spatial aggregation on reproductive success in a rewardless orchid [PDF]
, 2006 Plant reproductive success within a patch may depend on plant aggregation through pollinator attraction. For rewardless plants that lack rewards for pollinators, reproductive success may rely strongly on the learning abilities of pollinators.

Investigating Eusociality in Bees while Trusting the Uncertainty
Sociobiology, 2014 Phylogenetic hypotheses and estimates of divergence times have already been used to investigate the evolution of social behavior in all lineages of bees. The interpretation of the number of origins of eusocial behavior and the timing these events depends
