The species-specific responses to climate change can result in discordant range shifts, leading to changes in associations among species. In this study, we tested whether climate change can affect the spatial association between the plant Mimosa scabrella and the stingless bees Melipona quadrifasciata anthidioides and M. quadrifasciata quadrifasciata. Ecological niche models were used to predict current and future species distributions using intermediate (RCP 4.5) and high (RCP 8.5) greenhouse gas emission scenarios. Our models projected a pronounced reduction in climatically suitable habitats available for the studied species and identified a species-specific response to climate change. As a result, the models estimated a drastic reduction in the spatial association among species of up to 94% in the coming years, revealing that climate change may affect species interactions.

气候变化会影响巴西大西洋森林中无刺蜜蜂和含羞草之间的空间关联

物种对气候变化的特定反应可能导致不协调的范围变化，从而导致物种之间的关联发生变化。在这项研究中，我们测试了气候变化是否会影响植物含羞草与无刺蜜蜂 Melipona quadrifasciata anthidioides 和 M. quadrifasciata quadrifasciata 之间的空间关联。生态位模型用于使用中等 (RCP 4.5) 和高 (RCP 8.5) 温室气体排放情景预测当前和未来的物种分布。我们的模型预测，可供研究物种使用的气候适宜栖息地将显着减少，并确定了物种对气候变化的特定反应。因此，模型估计未来几年物种之间的空间关联将急剧减少多达 94%，
