How dogs don't ape
04-26-2007 · EurekAlert!New research by Friederike Range and Ludwig Huber, of the University of Vienna, and Zsofia Viranyi, of the Eötvös University in Budapest, reveals striking similarities between humans and dogs in the way they imitate the actions of others. The phenomenon under investigation is known as "selective imitation" and implies that dogs -- like human infants -- do not simply copy an action they observe, but adjust the extent to which they imitate to the circumstances of the action.

- At the root of nutrient limitation, ecosystems are not as different as they seem
11-08-2007 · EurekAlert!
Anyone who has thrown a backyard barbecue knows that hot dogs are inexplicably packaged in different numbers than buns -- eight hot dogs per pack versus 10 hot dog buns. Put in ecological terms, this means that weenie roasts are 'hot-dog limited' -- the extra buns are worthless without hot dogs to fill them. Such limiting factors are a cornerstone of natural ecology, where phosphorus or nitrogen limits plant production in most ecosystems.
