In social groups, infections have the potential to spread rapidly and cause disease outbreaks. Here, we show that in a social insect, the ant Lasius neglectus, the negative consequences of fungal infections (Metarhizium brunneum) can be mitigated by

Superorganism Immunity: A Major Transition in Immune System Evolution

Autor: Christopher D. Pull, Dino P. McMahon

Publikováno v: Frontiers in Ecology and Evolution, Vol 8 (2020)

Social insect colonies can express adaptive, organism-like design. In some cases, colonies so resemble a unique, cohesive and integrated “individual” that they are termed superorganisms. The major evolutionary transitions framework explains, via

Infections early in life can have enduring effects on an organism's development and immunity. In this study, we show that this equally applies to developing 'superorganisms'--incipient social insect colonies. When we exposed newly mated Lasius niger

Ecology dictates the value of memory for foraging bees

Autor: Christopher D. Pull, Cecylia Watrobska, Marta Perez Fernandez, Grégoire Pasquier, Ellouise Leadbeater, Irina Petkova

Summary “Ecological intelligence” hypotheses posit that the benefits of cognitive investment vary with foraging ecology, and provide a key framework for understanding the evolution of animal learning and memory1–4. However, although certain eco

Social insect societies are long-standing models for understanding social behaviour and evolution. Unlike other advanced biological societies (such as the multicellular body), the component parts of social insect societies can be easily deconstructed
