Adjustments in the time, distance and direction of foraging in dinoponera quadriceps workers

We measured individual decisions regarding the adjustments of time, distance and direction of foraging in Dinoponera quadriceps.We observed two colonies in an area of secondary Atlantic Forest, FLONA-ICMBio, in Northeastern Brazil. The workers were individually marked. We recorded the displacemen...

The workers were individually marked. We recorded the displacement of workers, their returns to the nest with and without food, the time spent searching for food, maximum and total distance, inter-trip latency and direction of trips. The time spent searching for food, maximum distance and transport velocity did not vary with food size. The previous trip success reduced the latency between foraging trips and increased the percentage of success on the next trip.
