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.

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.

The Mesosoma of Protanilla (Leptanillinae) and the Groundplan of the Formicidae (Hymenoptera). [PDF]

J Morphol
Phenomic investigation of the mesosoma of Protanilla lini reveals groundplan features of the ants and raises new homology questions for future investigation, both within Formicidae and across Aculeata. Special highlights include refined definition of the pronotum, complex discoveries of the promesothoracic articulation, and a new perspective on and ...

Diet composition of an escaped captive-born southern tamandua (Tamandua tetradactyla) in a nonnative habitat in Asia. [PDF]

Ecol Evol, 2022
Captive‐born lesser anteater can survive in nonnative habitat by expanding their food acceptance. The escaped lesser anteater fed on both sympatric and nonsympatric ant and termite taxa in Taiwan and survived for 3 months. Abstract Studies on the role of natural predatory instincts in captive‐born mammalian myrmecophagy are rare.

Allergy to stings and bites from rare or locally important arthropods: Worldwide distribution, available diagnostics and treatment

Allergy, Volume 78, Issue 8, Page 2089-2108, August 2023., 2023
Abstract Insect venom allergy is the most frequent cause of anaphylaxis in Europe and possibly worldwide. The majority of systemic allergic reactions after insect stings are caused by Hymenoptera, and among these, vespid genera induce most of the systemic sting reactions (SSR). Honey bees are the second leading cause of SSR.

Using computer vision to understand the global biogeography of ant color

Ecography, Volume 2023, Issue 3, March 2023., 2023
Organisms use color to serve a variety of biological functions, including camouflage, mate attraction and thermoregulation. The potential adaptive role of color is often investigated by examining patterns of variation across geographic, habitat and life‐history gradients.

A new putative species in the Ectatomma ruidum complex (Formicidae: Ectatomminae) produces a species-specific distress call [PDF]

Bioacoustics, 2021
Social insects communicate by using chemical, visual, tactile, and acoustic signals, including stridulations. Ectatomma ruidum is a mainly Neotropical ant species complex that has faced strong divergence at the genetic level; the species have a highly variable blend of cuticular hydrocarbons and a relatively conserved morphology.

Global biogeography of ant social parasites: Exploring patterns and mechanisms of an inverse latitudinal diversity gradient

Journal of Biogeography, Volume 50, Issue 2, Page 316-329, February 2023., 2023
Abstract Aim One of the most consistent global biogeographic patterns is the latitudinal diversity gradient where species richness peaks within the equatorial tropics and decreases towards the poles. Here, we explore the global biogeography of socially parasitic ant species, which comprises the most diverse group of social parasites in the Hymenoptera.

The ant abdomen: The skeletomuscular and soft tissue anatomy of Amblyopone australis workers (Hymenoptera: Formicidae)

Journal of Morphology, Volume 283, Issue 6, Page 693-770, June 2022., 2022
The ant abdomen is critically understudied, despite its functional, evolutionary, and systematic importance. Using physical dissection, scanning electron microscope, histology, and microcomputed tomography, we provide the first complete treatment of the skeletomusculature, exocrine glands, and other major organs of the abdomen.
