The predatory behavior of ants: an impressive panoply of morphological adaptations. [PDF]

Insect Sci
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Role of fetal head-circumference-to-maternal-height ratio in predicting Cesarean section for labor dystocia: prospective multicenter study. [PDF]

Ultrasound Obstet Gynecol, 2023
ABSTRACT Objective To evaluate the relationship between the fetal head‐circumference‐to‐maternal‐height (HC/MH) ratio measured shortly before delivery and the occurrence of Cesarean section (CS) for labor dystocia. Methods This was a multicenter prospective cohort study involving four tertiary maternity hospitals.

Cyatta abscondita: taxonomy, evolution, and natural history of a new fungus-farming ant genus from Brazil. [PDF]

PLoS ONE, 2013
Cyatta abscondita, a new genus and species of fungus-farming ant from Brazil, is described based on morphological study of more than 20 workers, two dealate gynes, one male, and two larvae. Ecological field data are summarized, including natural history,

Exposure of Workers of Ectatomma brunneum Smith (Hymenoptera: Formicidae: Ectatomminae) to ant Baits Containing Different Active Ingredients under Laboratory Conditions

EntomoBrasilis, 2015
This work evaluated the short-range mortality of workers of Ectatomma brunneum Smith when exposed to ant baits in laboratory, in order to verify if the attractiveness of this non-target species by ant baits intended to be used in the control of leaf ...

Mutualistic interactions between ants and fungi: A review

Ecology and Evolution, Volume 13, Issue 8, August 2023., 2023
We review the mutualistic interactions between ants and fungi. Neotropical myrmicine Attina cultivate Basidiomycota for food, the same being true for certain “plant‐ants” associated with myrmecophytes that also feed on Ascomycota fungi. Otherwise, these Ascomycota have antibacterial properties.

Microbial communities of the ant Formica exsecta and its nest material

European Journal of Soil Science, Volume 74, Issue 3, May–June 2023., 2023
This study compares the bacterial and fungal microbiomes of worker ants of Formica exsecta, and the nest material associated with the ants. We found that the ants maintain a microbiome, distinct from the surrounding nest material, and that this microbiome is consistent across colonies and time.

An Old World leaf‐cutting, fungus‐growing ant: A case of convergent evolution

Ecology and Evolution, Volume 13, Issue 3, March 2023., 2023
Crematogaster clariventris, a myrmicine ant from the African subgenus Atopogyne, is a defoliator that uses vegetal material to grow fungi as do higher New World leaf‐cutting Attina, illustrating a case of convergent evolution. However, C. clariventris grows fungal mycelia to reinforce the carton of the nests rather than cultivating it for food ...
