The tropical niche conservatism (TNC) hypothesis is one of the most prominent evolutionary hypotheses that has been supported as an explanation for the diversity gradients of several animal taxa, mainly vertebrates. However, the validity of TNC for less‐known taxa such as disease vectors is not clear. Here, we test predictions of TNC in driving the geographical co‐occurrence among triatomine species, vector insects of Chagas disease. We aim to infer the relative effects of ecological and evolutionary processes in determining triatomine species richness at broad spatial scales.

新世界三角藻物种之间地理共生的系统发生结构，南美锥虫病的载体

热带生态位保守性（TNC）假说是最重要的进化假说之一，已得到支持，可以解释几种动物类群（主要是脊椎动物）的多样性梯度。但是，TNC在鲜为人知的分类单元（例如病媒）上的有效性尚不清楚。在这里，我们测试了TNC在推动南美锥虫病物种，南美锥虫病矢量昆虫之间地理共生的预测。我们的目的是在广泛的空间尺度上推断生态和进化过程在确定三角藻类物种丰富度方面的相对影响。
