Invasive ants territorial when neighbors are not kin

A study led by University of California, San Diego biologists shows that invasive Argentine ants appear to use genetic differences to distinguish friend from foe, a finding that helps to explain why these ants form enormous colonies in California.

   12-17-2007 · EurekAlert!
   The ability of Argentine ants to change from carnivorous insect eaters to plant sap-loving creatures has helped these invasive social insects rapidly spread throughout coastal California, according to a new study, displacing many native insects and creating ant infestations familiar to most coastal residents.

3. Unpeaceful co-existence: How strengths and weaknesses maintain biodiversity in an ant community
   02-08-2007 · EurekAlert!
   Many species of ants scavenge for the same food, but the single most efficient species doesn't drive the others to extinction. Adler et al. modeled this unpeaceful co-existence. Some species are better at finding food while others are better at defending it. Some ants are efficient at both but flee when their own enemies (parasitoid flies) arrive.

4. Some caterpillers just don't want to grow up
   03-16-2007 · EurekAlert!
   An international project explores why it's an evolutionary advantage that only 25 percent of the caterpillars of Maculinea rebeli, a Lycaenid butterfly whose caterpillars live as parasites inside colonies of Myrmica ants, feeding on regurgitations from the nurse ants, complete development within one year. The rest are inactive and mature after two years. Intense competition and years where the ant colony avoids reinfection may be part of the explanation.

   06-27-2007 · EurekAlert!
   Insect queens were thought to have an egg-laying monopoly, but nine wood ant species revealed widespread reproductive activity by worker ants. Genetic analysis showed that as many as one in four eggs were laid by workers. Workers in many insect species can lay unfertilized male eggs, but usually workers in large colonies enforce the exclusive reproduction of the queen.

   The holidays just wouldn't be the same without the decorations. From a single wreath or child's picture of Santa taped to a window, to elaborate displays, the festive season seems to spur the need to express the holiday spirit to our neighbors and kin. But neighborhoods also vary in the vigor of their holiday displays, as anyone who tours the streets of their town or city can attest. And scientists at Binghamton University are using these decorations to measure holiday spirit.
