Novel Worker-Like Behavior Observed in Gynes of the Social Parasite <i>Tetramorium microgyna</i>. [PDF]
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.

Landscape configuration and soil properties shape ant-mediated seed dispersal in tropical dry forest agricultural landscapes. [PDF]
We show that ant‐mediated seed dispersal components respond differently to local soil conditions and landscape structure in Caatinga agricultural mosaics. Low‐intensity rainfed croplands maintained or enhanced seed removal compared to natural remnants, highlighting how small‐scale agriculture can sustain key ecological processes in human‐modified dry ...

Recognition and Aggression of conspecific and heterospecific worker in Acromyrmex subterraneus subterraneus (Forel) (Hymenoptera: Formicidae) [PDF]
Aggressive behavior is important for social insects because it makes possible for the colony to defend itself and the offspring from the action of invasive species.

Spiroplasma Display an Intricate Continuum of Infection Heterogeneity and Persistence in Myrmica Ants. [PDF]
ABSTRACT Many bacterial taxa evolved facultative symbiotic associations with insects and spread through host populations by horizontal and maternal transmission. Co‐infection at the individual host level may facilitate or constrain the spread of facultative symbionts.

Leafcutter Ant Farmers Prevent Loss of Edible Symbiotic Structures by Maintaining Allelic Diversity in Their Multinucleate Fungal Crop. [PDF]
ABSTRACT Leafcutter ants farm the domesticated fungal cultivar Leucoagaricus gongylophorus in subterranean nests containing up to hundreds of discrete garden chambers. The fungal cultivar produces edible symbiotic structures called gongylidia (nutritious swollen hyphal cells consumed by the ants) and expresses a form of polyploidy (multiple ...

The effect of homeopathic preparations on the activity level of Acromyrmex leaf-cutting ants=Atividade de formigas cortadeiras Acromyrmex spp. submetidas a preparações homeopáticas [PDF]
The effect of homeopathic preparations on the activities of the leaf-cutting ants Acromyrmex spp. was studied. A field experiment involving ant nests in six experimental areas was performed using a randomised complete block design.

A single Streptomyces symbiont makes multiple antifungals to support the fungus farming ant Acromyrmex octospinosus [PDF]
Attine ants are dependent on a cultivated fungus for food and use antibiotics produced by symbiotic Actinobacteria as weedkillers in their fungus gardens. Actinobacterial species belonging to the genera Pseudonocardia, Streptomyces and Amycolatopsis have

Many fungus-growing ants engage in a defensive symbiosis with antibiotic-producing ectosymbiotic bacteria in the genus Pseudonocardia, which help protect the ants’ fungal mutualist from a specialized mycoparasite, Escovopsis.
