For us humans, being lost isn’t all that much fun, often leading us to walk around in circles as we try to find our way. Apparently, some animals follow similar patterns.... http://www.redorbit.com/news/science/1112729597/sugar-ants-lost-111212/
OLDER MALE ANS SINGLE OUT YOUNGER RIVALS FOR DEATH SQUAD
The dominant wingless (ergatoid) male is able to identify potential rivals before they emerge from their pupae. Constant patrolling of the nest ensures that this male is able to bite or chemically tag rivals as soon as they emerge from their pupae. Chemically tagged ants are quickly destroyed by workers....
ANTS GIVES NEW EVIDENCE FOR SELF-DIRECTED INTERACTING NETWORKS
University of Arizona researchers have uncovered evidence in ant colonies that suggests that social networks may function differently than previously assumed. Be it through the Internet, Facebook, the local grapevine or the spread of disease, interaction networks influence nearly every part of our lives....
NATIVE ANTS USE CHEMICAL WEAPON TO TURN BACK INVADING ARGENTINE ANTS
Argentine ants are taking over the world ““ or at least the nice temperate parts. They’ve spread into Mediterranean and subtropical climates across the globe in sugar shipments from Argentina, and no native ant species has been known to withstand their onslaught ““ until now. A group of Stanford University undergraduate students working on a class project have discovered that a native species, the plucky winter ant, has been using chemical warfare to combat the Argentine tide.
ANT COLONIES: BEHAVIORAL VARIABILITY WINS Ant colonies with more behavioral variety are more successful / New findings in ant behavioral research
They attack other colonies, plunder and rob, kill other colonies’ inhabitants or keep them as slaves: Ants are usually regarded as prototypes of social beings that are prepared to sacrifice their lives for their community, but they can also display extremely aggressive behavior towards other nests....
PLOTTING AND TREACHERY ON ANT ROYAL FAMILIES
New research suggests that ant queens are also prepared to compromise the welfare of the entire colony in order to retain the throne. Often, an ant colony has more than one queen. Multiple queens can produce a larger initial workforce in incipient colonies, increasing the chance the colony will survive the hazardous first year. But queens do not happily cohabit forever; soon after the young workers hatch, they begin to slaughter surplus queens until only one remains.
