“…Moreover, overall group productivity was positively associated with r, as predicted by tug-of-war models. This association, which has previously been reported in some other social insects 20 , is expected from the lower investments in reproductive competition in groups where individuals are more related because of kin benefits. Finally, we also found that the tendency of females to join another female was significantly influenced by their relatedness: in the high-relatedness treatment, where females could readily associate with related individuals, the bees founded 33 multi-female and 30 single-female nests, versus 5 multifemale and 52 single-female nests in the low-relatedness treatment (two-sided Fisher's exact test, P , 0.0001).…”

One of the main transitions in evolution is the shift from solitary organisms to societies with reproductive division of labour. Understanding social evolution requires us to determine how ecological, social and genetic factors jointly influence group stability and partitioning of reproduction between group members. Here we test the role of the three key factors predicted to influence social evolution by experimentally manipulating them in a social allodapine bee. We show that increased relatedness between nestmates results in more even reproduction among group members and a greater productivity per individual. By contrast, the degree of reproductive skew is not influenced by the opportunity for solitary breeding or by the potential benefits of cooperation. Relatedness also has a positive effect on group stability and overall productivity. These findings are in line with predictions of the tug-of-war models, in which the degree of reproductive division of labour is determined primarily by selfish competition between group members. The alternative view, where the degree of reproductive skew is the outcome of a social contract between potential breeders, was not supported by the data.

“…Our results contrast with findings from other social insects, which show variable queen turnover rates. The serial polygynous wasp, Ropalidia marginata , showed frequent queen replacements, up to 10, throughout the year without a clear relation with the colony cycle (Gadagkar et al, 1993). Among Polistes wasps, dominance behavior is commonplace, where a single queen dominates the reproduction of the colony.…”

Invasive social insects rank among the most damaging of terrestrial species. They are responsible for extensive damage and severely threaten the biodiversity of environments where they are introduced. Variation in colony social form commonly occurs in introduced populations of yellowjacket wasps (genus Vespula). In particular, invasive colonies may contain multiple queens (i.e., polygyne) and persist several years, while in the native range, the colonies are usually annual and harbor a single queen (i.e., monogyne). In this study, we used genome-wide loci obtained by double digest restriction site-associated DNA sequencing (RADseq) to investigate the genetic structure and queen turnover in colonies of the western yellowjacket, Vespula pensylvanica, in their introduced range in Hawaii. Of the 27 colonies monitored over four months (October-January), 19 were polygyne and already contained multiple queens on the first day of sampling. Contrary to previous speculation, this finding suggests that polygyny often arises early in the annual colony cycle, before the production of new queens in the fall. Furthermore, polygyne colonies exhibited a prolonged average lifespan relative to those headed by a single queen. As a result, there is no clear window during which colony eradication efforts would be more effective than upon first discovery. The relatedness among nestmate queens was slightly above zero, indicating that these colonies are generally composed of nonrelatives. The queen turnover within each colony was low, and we detected some full-sibling workers sampled up to four months apart.Finally, we did not detect any population structure among colonies, suggesting that queens disperse up to several kilometers. Taken together, our results provide the first insights into the requeening dynamics in this invasive and incipiently polygyne population and illuminate the early establishment of multiple long-lasting queens in these damaging colonies.

“…This indirect communication in a self-organizing emergent system, where its individual parts communicate with one another by modifying their local environment, is called stigmergy (Abraham, Grosan & Ramos, 2006;Grassé, 1959). The most familiar examples of stigmergy, in natural systems, are observed in ants, bees, wasps, fish school, bird flocks, animal herds, and so on (Brothers, 1999;Gadagkar, 1993). It is this coordination mechanism used by these insects and other social animals that has inspired researchers to develop plenty of metaheuristic computing algorithms.…”

Biological studies highlighting the collective behavior of ants in fulfilling various tasks by using their complex indirect communication process have constituted the starting point for many physical systems and various ant colony algorithms. Each ant colony is considered as a superorganism which operates as a unified entity made up of simple agents. These agents (ants) interact locally with one another and with their environment, particularly in finding the shortest path from the nest to food sources without any centralized control dictating the behavior of individual agents. It is this coordination mechanism that has inspired researchers to develop plenty of metaheuristic algorithms in order to find good solutions for NP-hard combinatorial optimization problems. In this article, the authors give a biological description of these fascinating insects and their complex indirect communication process. From this rich source of inspiration for researchers, the authors show how, through the real ant, artificial ant is modeled and applied in combinatorial optimization, data clustering, collective robotics, and image processing.
