Blue-green orchid bees zip through increasingly scarce patches of tropical forest pollinating rare flowers. For the first time, researchers at the Smithsonian Tropical Research Institute track unique signals from tiny transmitters glued to individual orchid bees, yielding new insight into the role of bees in tropical forest ecosystems. "When people disturb and destroy tropical forest they disrupt pollination systems," said David Roubik, senior staff scientist at STRI. "Now we can track orchid...

A new study reveals the reason why orchids use sexual trickery to lure insect pollinators. The study, published in the January issue of The American Naturalist, finds that sexual deception in orchids leads to a more efficient pollinating system. While most flowering plants reward pollinators with tasty nectar, many orchid species turn to trickery. Some use what's called food deception. They produce flowers that look or smell like they offer food, but offer no edible reward. Other orchids use...

Harvard University scientists have determined some bees brace themselves against wind and turbulence by extending their hind legs while flying. Wind is a universal part of life for all flying animals, Assistant Professor Stacey Combes said. Yet we know remarkably little about how animals navigate windy conditions and unpredictable airflows, since most studies of animal flight have taken place in simplified environments, such as in still air or perfect laminar flows. Combes and Robert Dudley...

Turbulence hampers flight for various bee species, and possibly other insects New research shows some bees brace themselves against wind and turbulence by extending their sturdy hind legs while flying. But this approach comes at a steep cost, increasing aerodynamic drag and the power required for flight by roughly 30 percent, and cutting into the bees' flight performance. The findings are detailed in the Proceedings of the National Academy of Sciences. "Wind is a universal part of life for...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
