Investigating the role of non-helpers in group living thrips (2024)
Journal Article
Gilbert, J. (in press). Investigating the role of non-helpers in group living thrips. The journal of animal ecology,

1. Behavioural variation among individuals is a hallmark of cooperative societies, which commonly contain breeders and non-breeders, helpers and non-helpers. In some cases labour is divided, with non-breeders “helping”. Conversely, in some societies... Read More about Investigating the role of non-helpers in group living thrips.
