Forest Cover and Geographic Distance Shape Ant Assemblages in the Southwestern Brazilian Amazon. [PDF]

Ecol Evol
We investigated how forest cover, precipitation, and spatial distance influence ant species richness and composition in the southwestern Brazilian Amazon. We found that forest cover increases species richness, especially of forest specialists, while spatial distance is the main driver of variation in species composition.

Strumigenys perplexa (Smith, 1876) (Formicidae, Myrmicinae) a new exotic ant to Europe with establishment in Guernsey, Channel Islands [PDF]

Journal of Hymenoptera Research, 2021
Ants are continually introduced into regions outside of their natural biogeographic ranges via global trade. The genus Strumigenys Smith 1860 (Formicidae: Myrmicinae) are minute predators with a growing history of global introductions, although tropical ...

Mammalian herbivory indirectly shapes savanna arthropod communities but only at very low or high levels. [PDF]

J Anim Ecol
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.

Lectotype designation and redescription of four commonly collected Neotropical species of Strumigenys (Hymenoptera: Formicidae)

European Journal of Taxonomy, 2022
In 1887, Mayr described four species of the ant genus Strumigenys collected in the Brazilian state of Santa Catarina: Strumigenys unidentata, Strumigenys subedentata, Strumigenys denticulata, and Strumigenys crassicornis.

Threatened endemic arthropods and vertebrates partition their diets with non-native ants in an isolated island ecosystem. [PDF]

Ecology
Abstract The success of non‐native species depends on their ability to find food, which may ultimately lead to competition with native species and contribute to biodiversity loss in invaded ecosystems. Understanding which food resources are consumed is therefore crucial for evaluating how non‐native species mechanistically fit into native biological ...

A New Ant Species of Strumigenys Smith, 1860 (Hymenoptera: Formicidae) from the Brazilian Atlantic Forest

Taxonomy, 2023
Strumigenys is one of the largest genera of ants, and one of the few which has received relatively recent global taxonomic treatment at the species level. Despite this, many new species continue to be found in most biogeographic regions.

Foraging by predatory ants: A review. [PDF]

Insect Sci
This review focuses on ecological and behavioral characteristics of foraging in ants showing the wide diversity of cases. Most ants can feed on sugary substances, but some ground‐nesting species are strict predators. Except army ants during the nomadic phase, they are central‐place foragers that can recruit nestmates when necessary. They prey mostly on

Divergent evolution of colony-level metabolic scaling in ants. [PDF]

J Anim Ecol
The study shows for the first time that the metabolic scaling of active ant colonies varies as a function of trophic level and worker polymorphism. Therefore, the ecological divergence of metabolic scaling observed in unitary organisms occurs across levels of biological organization.

Vertical Stratification Increases the Capacity of Morphological Traits to Predict Trophic Position in Neotropical Ants. [PDF]

Ecol Evol
We use data from 73 Neotropical ant species to examine the strength of associations between nine morphological traits and trophic position. No individual morphological trait explained variation in the trophic position of arboreal species, whereas three traits individually correlated with the trophic position of ground species, but only weakly so ...
