We used mitochondrial cytochrome b and ND4 genes and 9 microsatellite loci to determine genetic diversity, population structure, evolutionary history, and migration patterns within the Reeves’ butterfly lizard Leiolepis reevesii (Agamidae). Considering molecular‐based phylogeographical lineages, we then performed niche equivalency and similarity tests between divergent lineages. Phylogenetic analyses based on mitochondrial DNA (mtDNA) data revealed 2 lineages (A and B) diverging ≈0.84 million years ago and, respectively, restricted to the northern and southern portions of the Wuzhishan and Yinggeling mountain ranges. Lineage B contains individuals from southern Hainan; Lineage A includes individuals from all other localities and can be further divided into 3 clusters according to microsatellite data. The null hypothesis that the 2 lineages shared identical niches was rejected in all niche equivalency tests, indicating niche shifts during genetic divergence. Similarity tests provided evidence of niche conservatism, suggesting that the 2 lineages share more characteristics of their niche spaces than randomly expected. The niche similarity and equivalency tests indicated a complex niche pattern in which both lineages share a main portion of their ecological spaces. The climatic niche of Lineage B represented a marginal and specialized fraction of the entire ecological space of the climatic niche of Lineage A, with warmer conditions. Isolation caused by orogenesis and subsequent niche divergence, together with local adaptation, may have led to genetic differentiation and further lineage sorting in L. reevesii.

Reeves的蝴蝶蜥蜴Leiolepis reevesii（Agamidae）中的血统多样化和小生境进化

我们使用线粒体细胞色素b和ND4基因以及9个微卫星基因座来确定里夫斯蝴蝶蜥蜴Leiolepis reevesii内的遗传多样性，种群结构，进化史和迁移模式（A科）。考虑基于分子的系统谱系，然后我们在不同谱系之间进行了利基当量和相似性测试。根据线粒体DNA（mtDNA）数据进行的系统发育分析显示，约有84万年前，有两个谱系（A和B）相距约84万年前，分别局限于五指山和英格令山脉的北部和南部。血统B包含海南南部的个体；沿袭A包括来自所有其他地方的个体，并且根据微卫星数据可以进一步分为3类。这两个谱系具有相同的生态位的原假设在所有利基当量测试中均被拒绝，这表明遗传差异期间的利基变化。相似性测试提供了利基保守性的证据，提示这两个世系比随机预期的拥有更多的利基空间特征。生态位相似性和等效性测试表明了复杂的生态位模式，其中两个谱系共享其生态空间的主要部分。世袭B的气候生态位代表了世袭A的气候生态位的整个生态空间的边缘化和专门化部分，条件更为温暖。由造山作用和随后的生态位差异引起的分离，再加上局部适应性，可能导致了遗传分化和进一步的沿袭分类。世袭B的气候生态位代表了世袭A的气候生态位的整个生态空间的边缘化和专门化部分，条件更为温暖。由造山作用和随后的生态位差异引起的分离，再加上局部适应性，可能导致了遗传分化和进一步的沿袭分类。世袭B的气候生态位代表了世袭A的气候生态位的整个生态空间的边缘化和专门化部分，条件更为温暖。由造山作用和随后的生态位差异引起的分离，再加上局部适应性，可能导致了遗传分化和进一步的沿袭分类。里氏乳杆菌。
