Abstract
Flexibility in the integration of environmental information by Dinoponera quadriceps Kempf during foraging
Highlights
Social foraging models characterize individuals according to their behavioral decisions
In this study, when it captured a prey the D. quadriceps worker returned to the nest in a roughly linear trajectory, as described by Araújo and Rodrigues (2006) and Azevedo and collaborators (2014)
A decrease in resolution time recorded on the second trip indicates that probably the ants adjust their route
Summary
Social foraging models characterize individuals according to their behavioral decisions. These decisions occur based on economic information about the fitness consequences of alternative actions. Learning is the mechanism involved in obtaining, storing and remembering the economic information (Giraldeau and Caraco, 2000). The evolution of spatial memory processes link to the emergence of the foraging area (Benhamou and Poucet, 1996). An individual becomes familiar with an area by learning landmarks and associating them with navigation information (Collett and Collett, 2000). Local navigation is the process of moving around the immediate environment, where only objects within the range of perception are useful (Trullier et al, 1997). Since experience generally involves a spatial sequence, these systems are not mutually exclusive (Beugnon et al, 1996)
