通过操纵资源或分散的机会，母亲可以迫使后代留在巢中帮助抚养兄弟姐妹，创造劳动分工。在次社会蜂Ceratina calcarata中，母亲操纵提供给第一个雌性后代的花粉的数量和质量，产生一个身材矮小的长女，身体较小，行为从属。这个女儿为她的兄弟姐妹觅食，放弃了自己的繁殖。为了了解母亲对花粉的操纵如何影响其后代的生理和行为，我们操纵了提供给后代的花粉量，并测量了花粉量对后代发育、成年体型和行为的影响。我们发现，通过实验操纵花粉量，我们可以重新创建矮长女表型，证明营养缺乏如何单独导致一个工人般的女儿的发展。具体来说，通过减少花粉和营养的后代，我们显着减少成年人的身体大小和脂质储存，创造显着减少侵略性，从属个人。工蜂在其他方面的独居行为开始解释母性对资源的操纵如何导致社会组织和生殖等级的发展，这是向高度社会行为过渡的重要一步。
By manipulating resources or dispersal opportunities, mothers can force offspring to remain at the nest to help raise siblings, creating a division of labor. In the subsocial bee Ceratina calcarata, mothers manipulate the quantity and quality of pollen provided to the first female offspring, producing a dwarf eldest daughter that is physically smaller and behaviorally subordinate. This daughter forages for her siblings and forgoes her own reproduction. To understand how the mother's manipulation of pollen affects the physiology and behavior of her offspring, we manipulated the amount of pollen provided to offspring and measured the effects of pollen quantity on offspring development, adult body size and behavior. We found that by experimentally manipulating pollen quantities we could recreate the dwarf eldest daughter phenotype, demonstrating how nutrient deficiency alone can lead to the development of a worker-like daughter. Specifically, by reducing the pollen and nutrition to offspring, we significantly reduced adult body size and lipid stores, creating significantly less aggressive, subordinate individuals. Worker behavior in an otherwise solitary bee begins to explain how maternal manipulation of resources could lead to the development of social organization and reproductive hierarchies, a major step in the transition to highly social behaviors.
