Ant diversity and species assemblages along an elevational gradient in the arid area of Central Iran [PDF]

Journal of Insect Biodiversity and Systematics
Ants (Hym., Formicidae) have been recognized as vital components of arid ecosystems. Determining the diversity patterns of ants and the ecological factors behind these patterns is expected to improve our understanding of the functioning of arid ...

Near-Optimum Soft-Output Ant-Colony-Optimization Based Multiuser Detection for the DS-CDMA uplink

, 2008
In this contribution, a novel soft-output Ant Colony Optimization (ACO) based Multi-User Detector (MUD) is proposed for the synchronous Direct-Sequence Code-Division- Multiple-Access (DS-CDMA) uplink.

Ant Colony Optimization Using Common Social Information and Self-Memory

Complexity, 2021
Ant colony optimization (ACO), which is one of the metaheuristics imitating real ant foraging behavior, is an effective method to find a solution for the traveling salesman problem (TSP).

Are Tree Species Diversity and Genotypic Diversity Effects on Insect Herbivores Mediated by Ants?

PLoS ONE, 2015
Plant diversity can influence predators and omnivores and such effects may in turn influence herbivores and plants. However, evidence for these ecological feedbacks is rare. We evaluated if the effects of tree species (SD) and genotypic diversity (GD) on

Conservation implications of divergent global patterns of ant and vertebrate diversity

, 2013
Aim: Global conservation planning is often oriented around vertebrates and plants, yet most organisms are invertebrates. To explore the potential conservation implications of this bias, we assessed how well patterns of diversity for an influential group ...

Learning Multi-Tree Classification Models with Ant Colony Optimization [PDF]

, 2014
Ant Colony Optimization (ACO) is a meta-heuristic for solving combinatorial optimization problems, inspired by the behaviour of biological ant colonies. One of the successful applications of ACO is learning classification models (classifiers).

Mechanisms of species coexistence and functional diversity of ant assemblages in forest and pasture habitats in southwestern Brazilian Amazon

Sociobiology, 2020
In this study, we investigated the mechanisms behind species coexistence and the relationships between functional diversity and species richness in ant assemblages in both forest and pasture habitats in the southwestern Brazilian Amazon. We addressed the

How to coexist with fire ants: The roles of behaviour and cuticular compounds [PDF]

, 2013
tBecause territoriality is energetically costly, territorial animals frequently respond less aggressively toneighbours than to strangers, a reaction known as the “dear enemy phenomenon” (DEP).
