The relative importance of biotic and abiotic factors in shaping the species diversity of temperate organisms has been debated for a long time. Here, we used drepanosiphine aphids as a model group to validate the ‘resource‐dependent hypothesis’ based on the biotic interactions for specialist herbivorous insects, a hypothesis stating that their intricate relationship with host plants for resources might constrain their species diversity from being positively correlated with the species diversity of their hosts, and to assess the role of biotic and abiotic factors in shaping the global species diversity pattern of temperate organisms.

食草性昆虫与其特定寄主之间物种多样性模式的高度相关性

生物和非生物因素在塑造温带生物物种多样性方面的相对重要性已经争论了很长时间。在这里，我们使用drepanosiphine蚜虫作为模型组，基于专业食草昆虫的生物相互作用来验证“依赖资源的假说”，该假说表明它们与宿主植物资源的错综复杂的关系可能会限制其物种多样性的正相关评估其宿主的物种多样性，并评估生物和非生物因素在塑造温带生物全球物种多样性格局中的作用。
