Novel Worker-Like Behavior Observed in Gynes of the Social Parasite <i>Tetramorium microgyna</i>. [PDF]

open access: yesEcol Evol
Our article reports, to our knowledge, the first observations of inquiline gynes performing worker tasks for their host colony. We dissected these gynes to establish that they were all unmated. We hypothesize that nest excavation by social parasites represents an artifact of a non‐parasitic past.

Ant Diversity and Stratification in an Amazonian Rainforest. [PDF]

open access: yesEcol Evol
We examined the three strata of an Amazonian rainforest (e.g., the ground and leaf litter, understory and canopy) using only two sampling techniques and analyzed their functional traits. We identified 494 ant species from 10 subfamilies and 77 genera over ≈3.0 ha, showing that they are species rich and abundant, particularly at ground level.

The self-organising clock pattern ofMessor pergandei (Formicidae, Myrmicinae) [PDF]

open access: greenInsectes Sociaux, 1989
A simple model is described wherein ant foragers choose a foraging sector as a function of the pheromone concentration associated with each sector. The choice is autocatalytic, as foragers that find food in a sector add to its pheromone. As a sector's food runs out, the foragers spontaneously switch to the adjacent sector.

Distribution Pattern of Ants in Huanglianshan National Nature Reserve From Yunnan, China. [PDF]

open access: yesEcol Evol
This study found that ant diversity in the Huanglian Mountain National Nature Reserve exhibits a non‐linear distribution pattern along the altitudinal gradient, encompassing 209 species across 9 subfamilies and 66 genera. Elevation significantly structured ant communities in the reserve.

Characterization of polymorphic microsatellite loci in the neotropical plant-ant Allomerus decemarticulatus (Formicidae: Myrmicinae) and multiplexing with other microsatellites from the ant subfamily Myrmicinae

open access: yesEuropean Journal of Entomology, 2010
Five polymorphic microsatellite loci of the arboreal ant Allomerus decemarticulatus (Myrmicinae) were isolated and characterized. The amplification and polymorphism of seven additional microsatellite loci, previously developed for the ant species A ...

Phylogenetic relationships among social parasites and their hosts in the ant tribe Tetramoriini (Hymenoptera: Formicidae)

open access: yesEuropean Journal of Entomology, 2000
The phylogenetic relationships among Palaearctic species of the ant genus Tetramorium and its social parasites of the genera Strongylognathtus, Anergates and Teletomyrmex, were investigated electrophoretically at 21 presumptive enzyme loci.

Multicoloniality in the highly polygynous ant Crematogaster pygmaea (Formicidae: Myrmicinae)

open access: yesEuropean Journal of Entomology, 2012
In social insects, the high variability in the number of queens per colony raises fundamental questions about the evolution of altruism. It is hypothesized, for instance, that nestmate recognition should be less efficient in polygynous than in monogynous

Identification and Functional Characterization of a Novel Insecticidal Decapeptide from the Myrmicine Ant Manica rubida

open access: yesToxins, 2019
Ant venoms contain many small, linear peptides, an untapped source of bioactive peptide toxins. The control of agricultural insect pests currently depends primarily on chemical insecticides, but their intensive use damages the environment and human ...
