Pacific white sharks stick to familiar waters
STANFORD (US)—The white shark may be the ultimate loner of the ocean, cruising thousands of miles in a solitary trek, but a team of researchers has discovered that white sharks in the northeastern Pacific Ocean have separated themselves into a population genetically distinct from sharks elsewhere in the world.

Wind energy that’s for the birds
“Conducting this research will help the wind industry make informed, science-based decisions about where future wind energy projects can be built and how they can be operated to minimize the impact on migrating wildlife, while still providing much-needed alternative energy,” explains John Fitzpatrick, director of the Cornell Lab of Ornithology.

Pairing radar, acoustics to track birds near wind farms
This animation illustrates the use of a network of surveillance weather radar to record nocturnal migrating birds, bats, and insects in the continental U.S. from sunset to sunrise Oct. 1, 2008. The blocky green, yellow, and red patterns, especially visible on the east coast, represent precipitation; but within an hour after sunset, radar picks up biological activity, as seen in the widening blue and green circles spreading from the east across the country. The birds, bats, and insects take off, fly past, and get sampled by the radar beam. Note, the black areas on the map do not represent places without birds, necessarily, but rather places where radar does not sample.
