In thisessay, we will explore the remarkable world of ants, delving into their intricate social structures, their ingenious engineering feats, and their remarkable adaptations to their environment. At the heart of the ant's success lies their highly organized social structure. Ants live in colonies...
Ant genomes: tools to study biological and social complexity Ants(Hymenoptera, Formicidae; seeGlossary) comprise a dominant component of most terrestrial habitats. The more than 14000 described species (http://www.antweb.org) show an enormous diversity in life-history features, ecological and behavio...
To investigate if the differences in bacterial abundance and composition affect survival, we either placed infected and sterile ants in their colony or kept them in isolation. The mortality after 36 h was much lower for infected ants kept with their nestmates (22%) than for infected ants kep...
Such a mechanism forms a positive feedback and eventually most of the ants, if not all, are able to transport food to their nest in the shortest path. Unlike natural ants, artificial ants exchange information on their quality via ant-decision rules determined by both pheromones and heuristic ...
The main objective of the ants is to find the shortest path between the nest and a food source. Suppose the ant path is defined within a graph G=(V,E). Using this algorithm, one can find the shortest existing path between two arbitrary vertices of graph G. Any edge that connects ...
the task it is performing and its actions are based on local decisions and are usually unpredictable, an ant colony expresses a complex collective behavior providing intelligent solutions to problems such as carrying large items, forming bridges and finding shortest routes from nest to a food source...
Restricted diaspore dispersal centred on long-lived ant mounds may explain the observed spatial structure at the first site whereas other forces appear to have contributed to the erosion of spatial structure at the second site. This multisite spatial study highlights the complexity of the interacting...
Center-of-origin theories, like many others, are often based on the unique features of the area: extensive shallow-water geological complexity, and contacts with two major biogeographic regions. Shallow basins may promote speciation within the region at low sea levels (McManus, 1985; Springer and...
Femur length has also been shown to be invariant or even positively correlated with habitat complexity (Guilherme et al., 2019; Parr et al., 2003). Eye size is also correlated both with habitat and with trophic level; ants living in subterranean or leaf litter habitats exhibit smaller eyes ...
