The cost of re-synchronization in a leaf-cutter ant colony [PDF]
Communications BiologyBiological rhythms are essential components of organisms' physiology and behavior. In social insects, biological rhythms can be studied at varying levels of a colony, revealing interesting aspects about how rhythms arise from the individual and collective levels.

The interplay between leaf-cutter ants behaviour and social organization
Journal of Umm Al-Qura University for Applied Sciences, 2023 AbstractLeaf-cutter ants (Atta and Acromyrmex species) exhibit complex social organizations that have fascinated scientists for decades. The leaf-cutter ants belong to a subgroup of fungus-growing ants, which live with fungus inside their nests. The behaviours exhibited by these ants are closely linked to their social organization, which involves ...

Multiple paternity, relatedness and genetic diversity in Acromyrmex leaf–cutter ants [PDF]
Proceedings of the Royal Society B: Biological Sciences, 1999 Multiple queen-mating occurs in many social insects, but high degrees of multiple paternity have only been found in honeybees and some yellowjacket wasps. Here we report the first case of an ant species where multiple mating reduces relatedness among female offspring to values significantly lower than 0.5. Genetic analysis of a Panamanian population of

Presence of Multiparasite Infections Within Individual Colonies of Leaf-Cutter Ants [PDF]
Environmental Entomology, 2010 Host-parasite dynamics can be altered when a host is infected by multiple parasite genotypes. The different strains of parasite are expected to compete for the limited host resources, potentially affecting the survival and reproduction of the host as well as the infecting parasites.

Microbial community structure of leaf-cutter ant fungus gardens and refuse dumps. [PDF]
PLoS ONE, 2010 BACKGROUND: Leaf-cutter ants use fresh plant material to grow a mutualistic fungus that serves as the ants' primary food source. Within fungus gardens, various plant compounds are metabolized and transformed into nutrients suitable for ant consumption ...

Large deformation diffeomorphic mapping of 3D shape variation reveals two distinct mandible and head capsule morphs in Atta vollenweideri leaf‐cutter worker ants [PDF]
Ecology and EvolutionAnts are crucial ecosystem engineers, and their ecological success is facilitated by a division of labour among sterile “workers”. In some ant lineages, workers have undergone further morphological differentiation, resulting in differences in body size ...

A biomechanical model for the relation between bite force and mandibular opening angle in arthropods
Royal Society Open Science, 2023 Bite forces play a key role in animal ecology: they affect mating behaviour, fighting success, and the ability to feed. Although feeding habits of arthropods have a significant ecological and economical impact, we lack fundamental knowledge on how the ...
