从独居到基于种姓的社会性的发展通常被认为是一个主要的进化转变。然而，最近的研究表明，在某些类群中，社会性可能是可塑的，并取决于当地的条件。如果社会性可以由环境驱动，那么问题就出现了，预测的气候变化将如何影响以前被认为具有宏观进化比例的社会组织的特征。根据春季的时间，在此期间，一个foundress可以产生工人的后代，汗蜂Halictus rubicundus是社会或孤独。我们分析了与英国气候变化预测有关的详细觅食数据，以评估何时何地可能会从孤独的生活方式转变为社会生活方式。我们表明，工人人数应增加整个英国预测的气候变化情况下，重要的是，社会性应该出现在北方地区，它以前从未被观察到。由于气候变化，社会组织发生了巨大变化，这将导致更多的劳动力可用于夏季授粉，并可能有助于缓解当前的传粉者危机。汗蜂Halictus rubicundus是社会多态性的，表现为孤独和社会形式，并且是社会可塑性的，能够根据当地的环境条件从孤独过渡到社会形式。在这里，我们分析了与英国气候变化预测相关的详细觅食数据，表明在预测的气候变化情景下，工人数量和社会性都有所增加。特别戏剧性的将是社会H的出现。特别是，如果发现更多的类群是社会塑料，环境驱动的社会组织的变化可能有助于减轻未来的传粉危机，提供更多的个人授粉。本文的在线版本（doi：10.1007/s 00265 -016-2118-y）包含补充材料，可供授权用户使用。
The progression from solitary living to caste-based sociality is commonly regarded as a major evolutionary transition. However, it has recently been shown that in some taxa, sociality may be plastic and dependent on local conditions. If sociality can be environmentally driven, the question arises as to how projected climate change will influence features of social organisation that were previously thought to be of macroevolutionary proportions. Depending on the time available in spring during which a foundress can produce worker offspring, the sweat bee Halictus rubicundus is either social or solitary. We analysed detailed foraging data in relation to climate change predictions for Great Britain to assess when and where switches from a solitary to social lifestyle may be expected. We demonstrate that worker numbers should increase throughout Great Britain under predicted climate change scenarios, and importantly, that sociality should appear in northern areas where it has never before been observed. This dramatic shift in social organisation due to climate change should lead to a bigger workforce being available for summer pollination and may contribute towards mitigating the current pollinator crisis. The sweat bee Halictus rubicundus is socially polymorphic, expressing both solitary and social forms, and is socially plastic, capable of transitioning from solitary to social forms, depending on local environmental conditions. Here, we analyse detailed foraging data in relation to climate change predictions for Great Britain to show that worker numbers and sociality both increase under predicted climate change scenarios. Especially dramatic will be the appearance of social H. rubicundus nests in the north of Britain, where previously only solitary forms are found. Particularly, if more taxa are found to be socially plastic, environmentally driven shifts in social organisation may help to mitigate future pollinator crises by providing more individuals for pollination.
