TLDR
The extraordinary success of social insects is partially based on division of labour, i.e. individuals exclusively or preferentially perform specific tasks as discussed by the authors, and task preference may correlate with morph morphology.Abstract:

A biomechanical model for the relation between bite force and mandibular opening angle in arthropods
TL;DR: In this article , a biomechanical model that characterizes the relationship between bite force and mandibular opening angle was derived from first principles and validated by comparing its geometric predictions with morphological measurements on the muscoloskeletal bite apparatus of Atta cephalotes leaf-cutter ants.

Strong positive allometry of bite force in leaf-cutter ants increases the range of cuttable plant tissues
TL;DR: It is demonstrated that bite forces in leaf-cutter ants need to be exceptionally large compared to body mass to enable them to cut leaves; and that the positive allometry enables colonies to forage on a wider range of plant species without the need for extreme investment into larger workers.

A biomechanical model for the relation between bite force and mandibular opening angle in arthropods
TL;DR: A comprehensive biomechanical model is derived that characterises the relationship between bite force and mandibular opening angle from first principles and suggests a hierarchy of model simplifications and assess the performance of ‘minimum’ models which predict bite force from a reduced set of easily accessible parameters.

The ant abdomen: The skeletomuscular and soft tissue anatomy of Amblyopone australis workers (Hymenoptera: Formicidae)
TL;DR: The abdominal anatomy of Amblyopone australis Erichson is described, using a multimodal approach combining manual dissection, histology, and microcomputed tomography, to provide a first approximation of the complete abdominal skeletomuscular groundplan in Formicidae.
Journal ArticleDOI
The First Reconstruction of the Head Anatomy of a Cretaceous Insect, †Gerontoformica gracilis (Hymenoptera: Formicidae), and the Early Evolution of Ants
TL;DR: The results support the notion of †Gerontoformica as ‘generalized’ above-ground predator missing crucial novelties of crown ants which may have helped the latter survive the end-Cretaceous extinction.

Caste and ecology in the social insects
George Oster,Edward O. Wilson +1 more
TL;DR: Oster and Wilson as discussed by the authors provided the first fully developed theory of caste evolution among the social insects and studied the effects of natural selection in generally increasing the insects' ergonomic efficiency.
