Male pregnancy: The dark side
SUMMARY: New research shows evidence for cryptic mate choice in Gulf pipefish. This is supported by two observations. First, males that mate with larger ("more desirable") females raise broods that have a higher survivorship. Second, embryo success in consecutive broods is negatively correlated. These observations show that males preferentially invest their limited resources into raising broods produced by "more desirable" females.
PS, Thanks Melissa for these links!

Go to Yale and learn Game Theory
Part of a series of lectures by Steven Stearns at Yale University. Yale University launched a program called Open Yale- where lecturers save all their course materials (including audio and video) and publish them freely online. Take a quick course in....
1. Freshman Organic Chemistry
2. Principles of Ecology and Evolutionary Biology and Behavior
3. Civil War and Reconstruction Era
4. Game Theory
....and much much more.
I haven't sat down and gone through the whole EEB course yet. I'll let you know what I think in a few days. In the meantime, you've got something to learn!!

"Pied piper" for bees?
How does a bee colony "decide" when to swarm? Apparently a small number of individuals perform a behavior called "piping" that triggers the group to follow them.

E.O. Wilson on saving life on Earth
"If all mankind were to disappear, the world would regenerate back to the rich state of equilibrium that existed ten thousand years ago. If insects were to vanish, the environment would collapse into chaos."E.O. Wilson on saving life on Earth | Video on TED.com
