Ants are friendly to some trees, but not others Tree-dwelling ants generally live in harmony with their arboreal hosts. But new research suggests that when they run out of space in their trees of choice, the ants can get destructive to neighboring trees. Contact: Kevin Stacey Public Release: 6-Nov-2009
AIBS publishes Darwin articles open access Two articles about Charles Darwin and his development of the theory of evolution by natural selection have been published in the AIBS journal BioScience and have been made open to the public in honor of the 150th anniversary of the publication of "On the Origin of Species." The articles are by Kevin Padian and James T. Costa. Together the articles dispel some common myths about Darwin the man and detail his efforts over many years to develop a theory to explain nature's diversity.

Caught in the act: Butterfly mate preference shows how 1 species can become 2 Breaking up may not be hard to do, say scientists who've found a population of tropical butterflies that may be splitting into two distinct species. The cause of this particular break-up? A shift in wing color and mate preference. In a paper published this week in the journal Science, the researchers describe the relationship between diverging color patterns in Heliconius butterflies and the long-term divergence of populations into new and distinct species.
