Population Diversity in Ant-inspired Optimization Algorithms

open access: yesComputer Science, 2021
Finding a balance between exploration and exploitation is very important in the case of metaheuristics optimization, especially in the systems leveraging population of individuals expressing (as in Evolutionary Algorithms, etc.) or constructing (as in Ant Colony Optimization) solutions.

Evolution of cuticular hydrocarbon diversity in ants. [PDF]

open access: yesJournal of evolutionary biology, 2011
The cuticular hydrocarbons (CHCs) of ants provide important cues for nest-mate and caste recognition. There is enormous diversity in the composition of these CHCs, but the manner in which this diversity has evolved is poorly understood. We gathered data on CHC profiles for 56 ant species, relating this information to their phylogeny.

A tale of scale: plot but not neighbourhood tree diversity increases leaf litter ant diversity.

open access: yesJournal of Animal Ecology, 2019
Diversity of producers (e.g. plants) usually increases the diversity of associated organisms, but the scale (i.e. the spatial area of plant diversity considered) at which plant diversity acts on other taxa has rarely been studied. Most evidence for cross-

Fossil Ants (Hymenoptera: Formicidae) of the Middle Eocene Kishenehn Formation

open access: yesSociobiology, 2015
A broad range of interesting fossil insects have been discovered recently in Kishenehn Formation shale (middle Eocene, ca. 46 myo) in northwestern Montana, among them a diversity of ant species.

Ant diversity patterns across tropical elevation gradients: effects of sampling method and subcommunity

open access: yesEcosphere, 2019
Local diversity may be influenced by niche assembly processes involving competition for limited resources, or by niche conservatism and the length of time clades have had to diversify.

Diversity and Resilience of Seed-Removing Ant Species in Longleaf Sandhill to Frequent Fire

open access: yesDiversity, 2022
Prescribed fire is used globally as a habitat restoration tool and is widely accepted as supporting biotic diversity. However, in fire-prone ecosystems, research has sometimes documented post-fire reduction in ant diversity and accompanying changes in ...

Community Structure of Leaf-Litter Ants in a Neotropical Dry Forest: A Biogeographic Approach to Explain Betadiversity

open access: yesPsyche: A Journal of Entomology, 2012
This paper describes habitat and geographic correlates of ant diversity in Serra da Bodoquena, a poorly surveyed region of central-western Brazil. We discuss leaf-litter ant diversity on a regional scale, with emphasis on the contribution of each of the ...

The Megadiverse Australian Ant Genus Melophorus: Using CO1 Barcoding to Assess Species Richness

open access: yesDiversity, 2016
Melophorus is an exceptionally diverse ant genus from arid Australia that has received little taxonomic attention, such that just a fraction of its remarkable number of species is described.

Ants of Ambon Island – diversity survey and checklist

open access: yesZooKeys, 2015
The present checklist of ants (Hymenoptera: Formicidae) of Ambon is the first comprehensive overview of ant species recorded on the island during the last 150 years. The species list is based on literature and museum collections' records combined with data from our field survey in 2010.

Ant Diversity Is Enhanced by Ecological Infrastructures in Agroecosystems: A Case Study in Irrigated Mediterranean Farmland

open access: yesAgronomy, 2022
We aimed at assessing the role of ecological infrastructures (EI) in promoting ant biodiversity in floodplain Mediterranean agricultural crops. We examined and compared ant communities at the interface between EI (remnant vegetation patches) and ...
