Mammalian preimplantation embryo development is a complex sequence of events. This period of development is sensitive to oxygen (O2) levels that can affect various cellular processes. We compared the influence of O2 tension by culturing emb...

Both species were collected with colonies of Acropyga ants (Hymenoptera: Formicidae) but only R. peripotaro was found to be trophobiotic; C. advena was ignored by the ants and is considered to be free-living. A guide to aid in identification is provided for each species.

Fungus-farming ants (Myrmicinae: Attini: Attina) form mutualistic associations with Agaricales fungi. The group is divided in lower and higher attine ants.

Caterpillars live on plants surrounded by ants throughout their entire ontogeny. Facultative symbiosis was observed in all instars with seven ant species in four genera. Myrmecophily is potentiated by honeydew-producing hemipterans and attractive sap of leaf lesions.

This is the case with the fungus Escovopsis (Ascomycota: Hypocreales), which attacks the fungus garden of attine ants (Formicidae: Attina) such as the leaf cutters.

Data from three and half years' nightly light-trap catches of 25 Afrotropical ant species were examined by Fourier analysis. Between 8 and 72 % of the seven-day-moving-average logarithmically transformed catches were accounted for by two to...

In temperate forests, ants did not prefer a particular nutrient in either stratum, likely due to extensive foraging across strata.

However, the significance of walking ants perceiving the relative motion of a landmark to themselves during learning is still not fully understood. Here, Japanese carpenter ants were observed on a treadmill device where they could walk in place on the treadmill....In the Y-maze test, a significantly greater number of ants in the moving training condition associated the landmark with food (82% of the ants) than in the fixed training condition (56% of the ants).

Strumigenys ants are characterized by an extraordinary developed exocrine system with 10 glands exclusively found in this genus. Making a survey of 18 species, we discovered two additional glands in workers and queens that are located underneath the anterior third of the 6th and 7th sternites....Whereas sternal glands in other ants often produce trail pheromones, this role can be excluded in Strumigenys as trail following does not occur in this genus.
