Effect of migration in a diffusion model for template coexistence in protocells [PDF]
, 2014 The compartmentalization of distinct templates in protocells and the exchange of templates between them (migration) are key elements of a modern scenario for prebiotic evolution.

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone
Insect Science, EarlyView.We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Origin and evolution of eusociality: a perspective from studying primitively eusocial wasps [PDF]
Journal of Genetics, 1990 Eusocial insects are those that show overlap of generations, cooperative brood care and reproductive caste differentiation. Of these, primitively eusocial insects show no morphological differences between reproductive and worker castes and exhibit considerable flexibility in the social roles that adult females may adopt.

Function and evolution of microRNAs in eusocial Hymenoptera
Frontiers in Genetics, 2015 The emergence of eusociality (true sociality) in several insect lineages represents one of the most successful evolutionary adaptations in the animal kingdom in terms of species richness and global biomass.

Allometry of individual reproduction and defense in eusocial colonies: A comparative approach to trade-offs in social sponge-dwelling Synalpheus shrimps. [PDF]
PLoS ONE, 2018 Eusociality, one of the most complex forms of social organization, is thought to have evolved in several animal clades in response to competition for resources and reproductive opportunities.

Insects, 2023 Termites are eusocial insects that live in organized colonies consisting of reproductives, workers, and soldiers. Soldiers are specialized for defense but are expensive to maintain, as they are incapable of husbandry and must be fed and groomed by ...

Should Evolution Necessarily be Egolution?
, 2017 In the article I study the evolutionary adaptivity of two simple population models, based on either altruistic or egoistic law of energy exchange. The computational experiments show the convincing advantage of the altruists, which brings us to a small ...

Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior
Integrative Zoology, EarlyView.Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.

Eusociality and cooperation. [PDF]
, 2001 The evolution of eusociality, here defined as the emergence of societies with reproductive division of labour and cooperative brood care, was first seen as a challenge to Darwin's theory of evolution by natural selection. Why should individuals permanently forgo direct reproduction to help other individuals to reproduce?

The weird eusociality of polyembryonic parasites [PDF]
Biology Letters, 2021 Some parasitoid wasps possess soldier castes during their parasitic larval stage, but are often neglected from our evolutionary theories explaining caste systems in animal societies. This is primarily due to the polyembryonic origin of their societies. However, recent discoveries of polyembryonic trematodes (i.e.
