Daily Bread for 8.29.11

Good morning.

It’s a sunny day ahead in the Whippet City, with a high temperature of eighty-one.

There’s a meeting of the Whitewater CDA today from 4.30 to 7 p.m., a portion of which will be in closed session.  The agenda is available online.

It turns out that not all worker ants are identical in their role within a colony, as previously thought.  Some are more influential than others —

Some worker ants are more equal than others.

As with other social insects, it was once thought that workers were essentially equivalent in ant colony hierarchies. But it appears that a few well-informed individuals shape group decisions by leading nestmates to new homes.

The findings could add a new dimension to ant-derived models of self-organization.

“Although self-organized systems appear very effective under the assumption that all individuals follow the same simple set of rules, the presence of key, well-informed individuals altering their behavior according to their prior experience might generally enhance performance even further,” wrote biologists from the University of Bristol and the University of Toulouse in an Aug. 24 Journal of Experimental Biology paper.
