...., 2004 ; Raguso, 2004 ; Thom et al., 2004 ). Insects such as social insects (ants, bees and termites) monitor CO 2 in their hives and control its concentration ( Stange and Stowe, 1999 ; Weidenmüller et al., 2002 ). Some specialized ORs are dedicated to sensing toxic odors. For instance, Or56a...

...Paul Graham; Michael Mangan ABSTRACT Visual navigation is a critical behaviour for many animals, and it has been particularly well studied in ants. Decades of ant navigation research have uncovered many ways in which efficient navigation can be implemented in small brains. For example, ants show us...

...Antoine Wystrach; Michael Mangan; Andrew Philippides; Paul Graham SUMMARY Ants can use visual information to guide long idiosyncratic routes and accurately pinpoint locations in complex natural environments. It has often been assumed that the world knowledge of these foragers consists of multiple...

... distance estimate. This is in striking agreement with findings in desert ants ( Ronacher et al., 2006 ; Sommer and Wehner, 2005 ). As strictly individual foragers, these animals may not exhibit a community odometer. The personal odometer, however, feeds into distance estimation, and thus path integration...

We developed an algorithm to accurately extract the positions of individuals moving in two dimensions. Our method...

...Yael Provecho; Roxana Josens SUMMARY Camponotus mus ants can associate sucrose and odour at the source during successive foraging cycles and use this memory to locate the nectar in the absence of other cues. These ants perform conspicuous trophallactic behaviour during recruitment while foraging...

...Roxana Josens; Claire Eschbach; Martin Giurfa SUMMARY Individual Camponotus fellah ants perceive and learn odours in a Y-maze in which one odour is paired with sugar (CS+) while a different odour(CS–) is paired with quinine (differential conditioning). We studied olfactory retention in C. fellah...
