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

Diversity, 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.

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

Diversity, 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 ...

Dominance–diversity relationships in ant communities differ with invasion [PDF]

Global Change Biology, 2018
AbstractThe relationship between levels of dominance and species richness is highly contentious, especially in ant communities. The dominance‐impoverishment rule states that high levels of dominance only occur in species‐poor communities, but there appear to be many cases of high levels of dominance in highly diverse communities.

Evolution of cuticular hydrocarbon diversity in ants [PDF]

Journal 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.

Contribution of wet zone coconut plantations and non-agricultural lands to the conservation of ant communities (Hymenoptera: Formicidae) in Sri Lanka [PDF]

Кавказский энтомологический бюллетень, 2020
Agricultural practices are blamed for the reduction of ant diversity on earth. Contribution of four coconut plantations (CP) and four non-agricultural lands (NL) for sustaining diversity and relative abundance of ground-dwelling and ground-foraging ants ...

Global diversity in light of climate change: the case of ants [PDF]

Diversity and Distributions, 2011
AbstractAim  To use a fine‐grained global model of ant diversity to identify the limits of our knowledge of diversity in the context of climate change.Location  Global.Methods  We applied generalized linear modelling to a global database of local ant assemblages to predict the species density of ants globally.

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

Psyche: 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 ...

Synthetic Genes for Artificial Ants. Diversity in Ant Colony Optimization Algorithms

International Journal of Computers Communications & Control, 2010
Inspired from the fact that the real world ants from within a colony are not clones (although they may look alike, they are different from one another), in this paper, the authors are presenting an adapted ant colony optimisation (ACO) algorithm that incorporates methods and ideas from genetic algorithms (GA). Following the first (introductory) section

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

Sociobiology, 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.

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

Advanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.
