Animals often need to make decisions about whether to confront risks, and climate change is making these decisions even more critical by increasing environmental stress. Biogenic amines are crucial for modulating behavior in all animals and may contribute to behavioral adaptations to changing environments through supporting decision-making involving risk. Our review focuses on the neuromodulator dopamine in insects because of its role in risk-related behavioral choices, particularly in the context of ant foraging activity. In ants, individual decisions contribute to the collective regulation of foraging activity. We consider the role of dopamine in the regulation of collective foraging activity to manage water loss in the desert red harvester ant, , in the southwest US that is undergoing severe drought. We discuss dopaminergic circuitry and its involvement in decisions about foraging risk, drawing from both the vertebrate and invertebrate literature, to outline areas of future research in the role of dopamine in collective decision-making in response to changing environmental conditions.
动物常常需要决定是否要面对风险，而气候变化通过增加环境压力，使这些决策变得更加关键。生物胺对于调节所有动物的行为至关重要，并且可能通过支持涉及风险的决策，促成对不断变化的环境的行为适应。由于神经调质多巴胺在与风险相关的行为选择中所起的作用，尤其是在蚂蚁觅食活动的背景下，我们的综述聚焦于昆虫体内的多巴胺。在蚂蚁群体中，个体决策有助于觅食活动的集体调节。我们探讨多巴胺在美国西南部正遭受严重干旱的沙漠收获蚁觅食活动中对水分流失的管理所起的调节作用。我们借鉴脊椎动物和无脊椎动物文献，讨论多巴胺能神经回路及其在觅食风险决策中的作用，以勾勒出未来关于多巴胺在应对不断变化的环境条件时在集体决策中作用的研究领域。
