Adaptive social immunity in leaf-cutting ants
Social insects have evolved a suite of sophisticated defences against parasites. In addition to the individual physiological immune response, social insects also express 'social immunity' consisting of group-level defences and behaviours that include allogrooming. Here we investigate whether the social immune response of the leaf-cutting ant Acromyrmex echinatior reacts adaptively to the virule...
متن کاملLeaf-cutting ants may be optimal foragers.
Kacelnikl proposes a puzzle for optimal foraging theorists, arising from experiments of Races and Nutiez2, who found that leaf-cutting ant (Acromyrmex lundi) workers changed their behavior in response to foragmg-quality information that was only known to scouts. The workers cut and transferred smaller pieces of parafilm when the scouts had been exposed to a 10% sugar solution than when they wer...
متن کاملMortality rates and division of labor in the leaf-cutting ant, Atta colombica
Division of labor in social groups is affected by the relative costs and benefits of conducting different tasks. However, most studies have examined the dynamics of division of labor, rather than the costs and benefits that presumably underlie the evolution of such systems. In social insects, division of labor may be simplistically described as a source-sink system, with external tasks, such as...
متن کاملGenetic polymorphism in leaf-cutting ants is phenotypically plastic.
Advanced societies owe their success to an efficient division of labour that, in some social insects, is based on specialized worker phenotypes. The system of caste determination in such species is therefore critical. Here, we examine in a leaf-cutting ant (Acromyrmex echinatior) how a recently discovered genetic influence on caste determination interacts with the social environment. By removin...
متن کاملContact rate modulates foraging efficiency in leaf cutting ants
Lane segregation is rarely observed in animals that move in bidirectional flows. Consequently, these animals generally experience a high rate of head-on collisions during their journeys. Although these collisions have a cost (each collision induces a delay resulting in a decrease of individual speed), they could also have a benefit by promoting information transfer between individuals. Here we ...
