A survey of orchid bees in the Brazilian Amazon state of Rond nia, carried out in the 1990s, is shedding new light the impact of deforestation on the scent-collecting pollinators, which some view as bellwethers of biodiversity in the neotropics.
A survey of orchid bees in the Brazilian Amazon state of Rondônia, carried out in the 1990s, is shedding new light the impact of deforestation on the scent-collecting pollinators, which some view as bellwethers of biodiversity in the neotropics."This study on orchid bees was an add-on to previous research on stingless bees.
Brown conducted all the fieldwork in 1996 based on a methodology developed with Marcio Oliveira, currently of the National Institute for Amazonian Research in Manaus, who was a fellow graduate student at the time. "Reviewers acknowledged the age of our data but commended the diversity of species we discovered and our unique methodology," Brown said."While conventional studies involve yearlong collection efforts in a handful of forest fragments, we sampled the bee population in 130 locations across the state in just an hour at each location. This unconventional approach revealed a wealth of bee diversity previously undocumented by others.
Brown said protecting orchid bee habitat and rainforests in general could largely be a matter of internal Brazilian politics and economics, but there were ways to boost their conservation. Pollination by insects is essential for the production of many food crops. The presence of pollinators, such as bees, depends on the availability of nesting sites and sufficient food. If these ...
