Ectatomma Opaciventre

	Ectatomma Opaciventre ''Ectatomma opaciventre'' is a South American species of ant from the subfamily Ectatomminae. In the Brazilian savannah, nests occur at low density and in specific microhabitats. Basic biology ''E. opaciventre'' is polydomous. Nests are excavated in soil and can be up be up to 68 cm deep, and comprise multiple sub-chambers. Foraging ecology The foraging ecology of ''E. opaciventre'' has been studies in detail. Workers forage diurnally, scavenging and predating live arthropods (primarily leaf cutter ants and termites). Opportunistically consuming dead and alive animal protein is typical of ''Ectatomma''. However, ''E. opaciventre'' has the least diverse diet of studied ants from the genus, and unlike others, does not collect liquid food. They forage individually, and show individual-level spatial fidelity in foraging habits ('path fidelity'). Behavior Temporal polyethism ''E. opaciventre'' exhibits temporal polyethism, with young workers performing more brood care and all ...

picture info	Ectatomma Opaciventre Concolor ''Ectatomma'' is a Neotropical genus of ants in the subfamily Ectatomminae. The genus contains 17 described extant species and one extinct species. Distribution and habitat ''Ectatomma'' is one of the most common genera in the Neotropical region, with most species being South American in their distribution, but others can be found in Central America as well as sparse populations in the Caribbean. ''Ecatomma'' may be found in rainforests, savannas, dry environments and cultivated areas.

	Ectatomminae Ectatomminae is a subfamily of ants in the poneromorph subfamilies group containing four extant and three extinct genera in two tribes. The subfamily was created in 2003 when Barry Bolton divided the Ponerinae subfamily into six subfamilies.

picture info	Tandem Running Tandem running is a pair movement coordination observed in ants and termites. In ants, tandem running is used for social learning, by which one ant leads another native ant from the nest to the food source it has found. Tandem running is also used to find and choose better, new nest sites to which the colony can emigrate. The follower ant maintains contact with the lead ant by frequently touching the leader's legs and abdomen with its antennae. As predators, scavengers, and herbivores, ants have a variety of food sources, for which they may journey as far as 200 meters from their nest, spraying a scent trail as they go. To lead their kin to new food sources, ants demonstrate one of the few examples of interactive teaching outside of the mammalian class. Social learning by teaching requires that the naive observer change its behavior and acquire some skills or knowledge faster than it would have independently and that the teacher incur some cost. In order for the follower ant to le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Pheromone Trail Trail pheromones are semiochemicals secreted from the body of an individual to affect the behavior of another individual receiving it. Trail pheromones often serve as a multi purpose chemical secretion that leads members of its own species towards a food source, while representing a territorial mark in the form of an allomone to organisms outside of their species. Specifically, trail pheromones are often incorporated with secretions of more than one exocrine gland to produce a higher degree of specificity. Considered one of the primary chemical signaling methods in which many social insects depend on, trail pheromone deposition can be considered one of the main facets to explain the success of social insect communication today. Many species of ants, including those in the genus ''Crematogaster'' use trail pheromones. Background In 1962, Harvard professor Edward O. Wilson published one of the first concrete studies constructing the groundwork for the notion of trail pheromones. Clai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
