The first cytogenetic data on Strumigenys louisianae Roger, 1863 (Formicidae: Myrmicinae: Dacetini): the lowest chromosome number in the Hymenoptera of the neotropical region. [PDF]

PLoS ONE, 2014
In the present study, the first cytogenetic data was obtained for the ant species Strumigenys louisianae, from a genus possessing no previous cytogenetic data for the Neotropical region.

Mammalian herbivory indirectly shapes savanna arthropod communities but only at very low or high levels

Journal of Animal Ecology, EarlyView.
This study investigates how large mammalian herbivores shape arthropod communities in African savannas, using a broad gradient of herbivory types and intensities to assess these effects under real‐world, non‐experimental conditions. Abstract Savanna ecosystems support unique biodiversity and provide livelihoods for millions of people.

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
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 ...

Habitat Amount Shapes Ant Diversity in the Central Amazon

Biotropica, Volume 58, Issue 1, January 2026.
Ant diversity in fragmented Amazonian forest landscapes is primarily driven by landscape‐scale habitat amount rather than fragment size, supporting the Habitat Amount Hypothesis (HAH) over Island Biogeography Theory (IBT). Consequently, conservation strategies should prioritize maintaining and restoring forest cover across human‐modified landscapes ...

Epigaeic ant (Hymenoptera: Formicidae) communities in urban parks located in Atlantic Forest biome [PDF]

Check List, 2016
Urban parks offer refuge for numerous animal species, and some of these parks represent the remaining fragments of native forests. We evaluate the diversity and composition of epigaeic ant species (Hymenoptera: Formicidae) in urban parks located within ...

The Larva of Acanthognathus (Hymenoptera: Formicidae)

Psyche: A Journal of Entomology, 1969
In 1953 Brown divided the tribe Dacetini into four subtribes: Dacetiti, Orectognathi, Epopostrumiti and Strumigenitio. After studying the larvae of eight dacetine genera (Daceton, Orectognathus, Epopostruma, Mesostruma, Alistruma, Clarkistruma ...

The preference for energetic resources is positively associated with predatory activity in ants

Ecological Entomology, Volume 50, Issue 5, Page 921-932, October 2025.
We found that ants exhibit a stronger preference for foraging for carbohydrates and lipids (energetic nutrients) compared to amino acids. The increase in foraging for energetic nutrients compared to amino acids is positively correlated with foraging in larvae (insect predation). The nutrient preference between foraging for energetic nutrients and amino

Tropical Biome Switching: Ant Communities Transition From Savanna to Rainforest Following Cessation of Burning

Journal of Biogeography, Volume 52, Issue 9, September 2025.
ABSTRACT Savannas and rainforests co‐occur as mosaics across large areas of the tropics. These mosaics are dynamic, with savanna and rainforest switching in relatively short time scales, largely through the effects of fire. Most research to date addresses such biome switching through the lens of vegetation, with little attention given to faunal ...

Notes on Ants of the genus Strumigenys F. Smith, 1860 (Hymenoptera: Formicidae) in the Arabian Peninsula, with a key to species.

Sociobiology, 2014
The ant genus Strumigenys in the Arabian Peninsula is treated. Three species are recognized, S. arnoldi Forel, S. emmae (Emery) and S. membranifera Emery. The invasive species S. membranifera and the Afrotropical species S.
