了解气候介导的生物相互作用如何塑造热生态位宽度在全球变化的时代至关重要。然而，大多数以前的工作热生态位忽略了详细的机械信息之间的关系，温度和生物体的性能，这可以描述的热性能曲线。在这里，我们开发了一个模型，预测的热性能曲线的宽度将在种间竞争对手的存在下，导致一个物种的最佳繁殖温度偏离的竞争对手。我们测试这一预测在亚洲埋葬甲虫Nicrophorus尼泊尔，确认分歧的实际和最佳的繁殖温度是与绿头苍蝇竞争的结果。然而，我们进一步表明，种内合作，使甲虫通过恢复他们的最佳繁殖温度，以胜过绿头苍蝇。最终，将生态位宽度的直接（非生物因素）和间接影响（生物相互作用）联系起来对于理解物种对气候变化的反应至关重要。
Understanding how climate-mediated biotic interactions shape thermal niche width is critical in an era of global change. Yet, most previous work on thermal niches has ignored detailed mechanistic information about the relationship between temperature and organismal performance, which can be described by a thermal performance curve. Here, we develop a model that predicts the width of thermal performance curves will be narrower in the presence of interspecific competitors, causing a species’ optimal breeding temperature to diverge from that of a competitor. We test this prediction in the Asian burying beetle Nicrophorus nepalensis, confirming that the divergence in actual and optimal breeding temperatures is the result of competition with blowflies. However, we further show that intraspecific cooperation enables beetles to outcompete blowflies by recovering their optimal breeding temperature. Ultimately, linking direct (abiotic factors) and indirect effects (biotic interactions) on niche width will be critical for understanding species-specific responses to climate change.
