“…Solitary founding by mated, wingless queens and budding may be difficult, making nest inheritance a realistic alternative. Nevertheless, as mentioned above, many young queens of C. 'argyrotricha' do not shed their wings after mating [45] and, in accordance with dispersal models (e.g. [51]), may maintain their option for long-distance dispersal.…”

“…[41]). Two lineages-a few species of the Southeast Asian Cardiocondyla 'argentea' group ( preliminary name for a taxon currently being described by B. Seifert) and the large clade of Palaearctic Cardiocondyla-have convergently evolved singlequeening (monogyny) [10,[43][44][45]. Nevertheless, both lineages have retained intranidal mating, which results in the temporary presence of multiple potential reproductives in a single nest.…”

Ants are important components of most terrestrial habitats, and a better knowledge of the diversity of their life histories is essential to understand many aspects of ecosystem functioning. The myrmicine genus Cardiocondyla shows a wide range of colony structures, reproductive behaviours, queen and male lifespans, and habitat use. Reconstructing the evolutionary pathways of individual and social phenotypic traits suggests that the ancestral life history of Cardiocondyla was characterized by the presence of multiple, short-lived queens in small-sized colonies and a male polyphenism with winged dispersers and wingless fighters, which engage in lethal combat over female sexuals within their natal nests. Single queening, queen polyphenism, the loss of winged males and tolerance among wingless males appear to be derived traits that evolved with changes in nesting habits, colony size and the spread from tropical to seasonal environments. The aim of this review is to bring together the information on life-history evolution in Cardiocondyla and to highlight the suitability of this genus for functional genomic studies of adaptation, phenotypic plasticity, senescence, invasiveness and other key life-history traits of ants.

“…The selection of the VEQ destined to become the new reproductive queen remains unknown. Two hypotheses may be proposed: (1) the occurrence of a social hierarchy among ergatoids, with the dominant VEQ developing her ovaries in the absence of the reproductive queen (e.g., Leptothorax sp.A, Heinze and Smith 1990; Diacamma sp., Peeters and Tsuji 1993;Dinoponera quadriceps, Monnin and Peeters 1999) and (2) after the disappearance of the reproductive queen, a new VEQ emerges with developed ovaries and inherits the nest (e.g., Cardiocondyla argyrotricha, Schmidt et al 2017). In contrast to the VEQs, workers of O. robustior do lay eggs in both queenright and in queenless nests, as evidenced by the presence of yellow bodies.…”

Population structure and sociogenetic organisation in a species with ergatoid queens, the desert ant Ocymyrmex robustior

In ants, reproductive division of labour is typically associated with queen-worker dimorphism. In some species with ergatoid queens (wingless worker-like queens), this polymorphism is drastically reduced and virgin queens may integrate the worker force. While ergatoid queens have been described in several species, their colony and population genetic structure remain largely unstudied. Here, we investigated the population structure and sociogenetic organisation of the desert ant Ocymyrmex robustior. All Ocymyrmex species have only ergatoid queens that are worker-sized. Workers, queens, and males from a large population were genotyped at ten polymorphic microsatellite loci. Our results show that the study population is genetically structured, consistent with dependent colony foundation. Genetic analyses revealed that 17.6% of the males were diploid; diploid males are fertile, siring triploid females. Nests were typically headed by a single queen, and queens were strictly monandrous. However, several nests in the population shared matrilines, indicating polygyny, polydomy, dependent colony foundation, serial polygyny, or a combination of these processes. Dissections reveal that workers lay eggs in both queenright and queenless nests, while virgin ergatoid queens lay eggs in queenright nests only. However, our genetic analyses show that male offspring in queenright nests are all queen-produced, suggesting worker policing and/or trophic egg laying.

“…However, the aircraft with a low landing speed may increase the waiting duration of other faster ones which affect the total landing duration. In addition, FCFS limits flexibility to air traffic controllers to act in emergency situations (Vairaktarakis and Aydinliyim 2017;Schmidt et al 2017; NASA Air Traffic Management Demonstration Goes Live in Charlotte 2017). Hence, we propose a use a new approach based on real-time scheduling algorithm, Deadline Monotonic (DM) in our case (Jarrar et al 2017).…”

Complex Adapt Syst Model

Air traffic control system studied in this paper is a complex adaptive socio-technical system that controls the traffic of all aircrafts in the airport's radar range. The complexity of this system arises due to the number of elements and factors intervene in it such as aircrafts, controllers, runways, taxiways, weather, etc. This complexity makes the system unpredictable which require a real time management and adaptation of a dynamic state. The dynamic state means that during system building we cannot know which aircrafts will enter the airport neither their arrival nor departure time. All these facts makes developing air traffic control system a significant and challenging task in the context of air traffic management. We describe this complex adaptive socio-technical system using a model based on a complex network. This kind of complex network is often represented using a graph where nodes represent aircrafts (agents) and edges represent the exchange of data over the network. In a complex network we define strategies describing the behaviour of aircrafts in all situations. These strategies should be carefully defined to maintain the stability of the system and avoid any mistake that could leat to a disaster. This high risk can be avoided by using sophisticated techniques such as formal methods during system design. Formal methods are mathematically based techniques for specifying and verifying systems. Use of those methods can greatly increase our understanding of a system by revealing inconsistencies, ambiguities, and incompleteness that might otherwise go
