A Remarkable New Dimorphic Species of Solenopsis from Argentina [PDF]

Sociobiology, 2015
Solenopsis Westwood (Myrmicinae: Solenopsidini) is an ant genus that represents a taxonomical challenge including about 117 species in the New World, most of them Neotropical.

A revision of the Neotropical Solenopsidini ant genus Oxyepoecus Santschi, 1926 (Hymenoptera: Formicidae: Myrmicinae): 2. Final. Key for species and revision of the Rastratus species-group [PDF]

Papéis Avulsos de Zoologia, 2009
In the first paper of this series (Albuquerque & Brandão, 2004) we revised the Vezenyii species group of the exclusively Neotropical solenopsidine (Myrmicinae) ant genus Oxyepoecus. In this closing paper we update distribution information on the Vezenyii

Effect of Time-Since-Fire on Ant Communities in a Semi-Arid Landscape. [PDF]

Ecol Evol
We sampled ants from five sites with varying fire histories (3, 5, 9, 26, and 34 years since the last fire). A total of 16,360 ants were collected, and 59 species across 20 genera were identified. Our results indicate that total ant abundance was higher in recently burnt sites and decreased with increasing time‐since‐fire, while ant species richness ...

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

Ecol 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.

Beyond Species Diversity: Functional Approaches Reveal Consistent Fauna Community Responses to Exotic Grass Invasion in Arid Lands. [PDF]

Ecol Evol
To assess whether the impacts of exotic plant invasion can be generalised across taxa, we developed a conceptual framework predicting faunal responses to grass invasion in open, arid ecosystems and tested our predictions using data on birds, reptiles and ants from sites invaded by buffel grass (Cenchrus ciliaris) and paired uninvaded sites.

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

Ecol 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.

Expansion of the geographic range of Cyatta abscondita Sosa-Calvo et al., 2013 (Hymenoptera: Formicidae) [PDF]

, 2016
The presence of the recently described fungus-farming ant genus and species Cyatta abscondita is reported in the northwestern region of Misiones Province in Argentina. A single worker of C.

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

European 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 ...

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

Toxins, 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 ...

The complete mitochondrial genome of Aphaenogaster famelica (Smith, 1874) (Hymenoptera: Formicidae)

Mitochondrial DNA. Part B. Resources, 2020
Aphaenogaster famelica (Smith, 1874) is a slender ant found in Korea. We have completed the mitochondrial genome of A. famelica of which length is 19,464 bp, the third longest ant mitogenome so far.
