Pollination, essential to much of life on earth, requires the explosive death of the male pollen tube in the female ovule. In new research, Brown University scientists describe the genetic and regulatory factors that compel the male’s role in the process. Finding a way to tweak that performance could expand crop cross-breeding possibilities.

In recent years the economic value of pollination-dependent crops has substantially increased around the world. As a team of researchers from the Helmholtz Centre for Environmental Research (UFZ), the Technical University of Dresden and the University of Freiburg headed by the UFZ wrote in an article entitled "Spatial and temporal trends of global pollination benefit" in the open-access journal PLoS ONE the value of ecological pollination services was around 200 billion US dollars in 1993 and rose to around 350 billion US dollars in 2009.

In an irony of nature, invasive species can become essential to the very ecosystems threatened by their presence, according to a recent discovery that could change how scientists and governments approach the restoration of natural spaces.

The honeybee has hogged the pollination spotlight for centuries, but native bees are now getting their fair share of buzz: They are two to three times better pollinators than honeybees, are more plentiful than previously thought and not as prone to the headline-catching colony collapse disorder that has decimated honeybee populations, says Cornell entomology professor Bryan Danforth.
