Foraging by predatory ants: A review
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

ABSTRACT Social insects form complex societies with division of labour between different female castes. In most species, a single queen heads the colony; in others, several queens share the task of reproduction. These different social organisations are often associated with distinct queen morphologies and life‐history strategies and occur in different ...

Social Organization Is Associated With Relaxed Selection on Worker Genes in Highly Polygyne Ants
ABSTRACT Ants display a diversity of social structures reflected by differences in caste, nest, and colony organization. Previous research has shown that highly eusocial insects (Hymenoptera) exhibit genome‐wide signatures of relaxed selection due to their smaller effective population sizes.

São poucos os taxonomistas que atuam na identificação de formigas cortadeiras. Os métodos morfométricos utilizados nem sempre permitem uma identificação confiável, em função do acentuado polimorfismo dentro do mesmo formigueiro.

This paper describes the morphology and chemical contents of the pre‐pharyngeal and pharyngeal glands in two different ants. The results provide new insights about the morphology and compounds of the exocrine glands in ants. ABSTRACT Ants occur in a remarkable diversity of species, many of which fulfill essential ecological roles and exhibit complex ...
