Task partitioning in insect societies. I. Effect of colony size on queueing delay and colony ergonomic efficiency [PDF]

, 1999
The collection and handling of colony resources such as food, water, and nest construction material is often divided into subtasks in which the material is passed from one worker to another. This is known as task partitioning.

Protecting an Ecosystem Service: Approaches to Understanding and Mitigating Threats to Wild Insect Pollinators [PDF]

, 2016
Insect pollination constitutes an ecosystem service of global importance, providing significant economic and aesthetic benefits as well as cultural value to human society, alongside vital ecological processes in terrestrial ecosystems.

Insights into the dynamics of hind leg development in honey bee (Apis mellifera L.) queen and worker larvae - A morphology/differential gene expression analysis

Genetics and Molecular Biology, 2015
Phenotypic plasticity is a hallmark of the caste systems of social insects, expressed in their life history and morphological traits. These are best studied in bees.

Sanitizing the fortress: protection of ant brood and nest material by worker antibiotics [PDF]

, 2013
Social groups are at particular risk for parasite infection, which is heightened in eusocial insects by the low genetic diversity of individuals within a colony. To combat this, adult ants have evolved a suite of defenses to protect each other, including

Temnothorax caryaluteus sp. nov. (Hymenoptera: Formicidae): a new ant species from the eastern United States

European Journal of Taxonomy
Although the ant genus Temnothorax is broadly distributed, extremely diverse, and contains multitudes of undescribed species, discovering new Temnothorax species in the eastern United States is rare due to the high concentration of taxonomic effort on ...

A Potential Role for Phenotypic Plasticity in Invasions and Declines of Social Insects

Frontiers in Ecology and Evolution, 2019
Eusociality, a form of animal social organization involving sterile and reproductive castes, is a rare, but highly ecologically successful form of life.

Starvation resistance and tissue-specific gene expression of stress-related genes in a naturally inbred ant population [PDF]

Royal Society Open Science, 2016
Starvation is one of the most common and severe stressors in nature. Not only does it lead to death if not alleviated, it also forces the starved individual to allocate resources only to the most essential processes.

Variation in Chemical Composition of Cuticular and Nonpolar Compounds of Venom of Apoica pallens and Polistes versicolor

Sociobiology, 2019
Although cuticular hydrocarbons and venom are important to the evolutionary success of social behavior, studies that investigated these compounds in tropical social wasps are rare.

How Can Termites Achieve Their Unparalleled Postembryonic Developmental Plasticity? A Test for the Role of Intermolt-Specific High Juvenile Hormone Titers

Frontiers in Ecology and Evolution, 2021
Termites are “social cockroaches” and amongst the most phenotypically plastic insects. The different castes (i.e., two types of reproductives, workers, and soldiers) within termite societies are all encoded by a single genome and present the result of ...

Trade-offs between personal immunity and reproduction in the burying beetle, N. vespilloides [PDF]

, 2014
We know that parental investment and immune investment are costly processes, but it is unclear which trait will be prioritised when both may be required.
