coevolution
awild | June 26, 2009A few months ago we learned via an unintentionally leaked press release that a team of researchers lead by Nicole Gerardo and Cameron Currie had won a Roche Applied Sciences grant competition. The team will be sequencing the complete genome of 14 players from the ant/fungus/microbe co-evolutionary system, including three attine ants from different genera.
The announcement is now official.

Brood parasites are birds, fish or insects that deceive unrelated animals of the same species or different species to care for their offspring. By doing so, the parasitic parent is relieved of the energetic demands of constructing a nest and raising its young to independence…

A neotropical black ant, Cephalotes atratus,
infected with the newly described parasitic nematode,Myrmeconema neotropicum.
The ant's infected and swollen abdomen does not actually take on a red pigment.
It becomes a translucent amber. With the yellowish parasite eggs inside and a touch
of sunlight, it appears bright red.
