Ants like to travel along the trails that have the strongest pheromone scent. In areas where food is scarce, ants need to conserve their resources (i.e., not send too many ants out to look for food).

Behavior is instigated whenever a match between the environment and the context encoded in the structure occurs.
Ant behaviour and brain gene expression of defending hosts depend on the ecological success of the intruding social parasite. A returning worker ant drops the seed at the entrance tunnel to the nest, where it’s transported by another ant deeper into the nest. In this case, fewer ants are sent out to join the hunt. Over time, the individual further strengthens and deepens the action structure as variations of the behavior are performed in different contexts ( Kuhl 1985, 103–7, offers a detailed exposition). *, (2019) Gene expression is more strongly associated with behavioural specialisation than with age or fertility in ant workers.

Need help? Our lab is interested in epigenetic mechanisms that establish, sustain, and modulate caste-based division of behavior, using the evolutionarily divergent ants Our current projects focus on understanding how chromatin factors contribute to critical periods of behavioral plasticity during early adult life, as well as the closing of such critical periods later in life.
"If we can understand how rules emerge from other rules and … More than 10,000 known ant species occur around the world. That explains why you see ants marching in a straight line directly toward your picnic.Red harvester ants feed on seeds that are scattered by the wind instead of collecting in patches, so they forage individually instead of following pheromone trails. Furthermore, we are also interested in studying how caste determination triggered and settled in larval and pupal developmental stages, using multi-omic and single-cell profiling approaches.Using this extremely complex social system, we are trying to identify epigenetic regulators of this advanced caste-based system.9th Floor Smilow Bldg | Room 9-125 Smilow | 3400 Civic Center Blvd | Philadelphia, PA 19104215-746-3106 | bergers@upenn.edu | andes@upenn.edu Three castes of ants perform different roles in the colony:Many ant species communicate using chemical scents called pheromones.
In this book, we will present our latest findings on non-invasive sensing and understanding of human behavior. We are using single-cell transcriptome and epigenome sequencing techniques to dissect the ant brain heterogenety and identify caste and cell-type features regulating caste specification. After the ant finds Pheromones explain this common ant behavior. When food is scarce, the foragers have to travel further, so they return more slowly.
