Calicina 属收获者有 25 种短程特有物种，分布于内华达山脉西部、加利福尼亚州横向和海岸山脉。我们的主要目的是重建该蜘蛛纲动物谱系的时间和空间生物地理历史。我们使用多基因和基于多位点聚结的方法，推断出 25 个描述的 Calicina 物种中的 21 个的时间校准物种树。该物种树被用作算法生物地理学和分歧时间分析的框架，并使用系统发育典型相关分析（CCA）来检查形态进化和环境变量之间的关系。物种树和生物地理学分析表明，高海拔山脉类群在卡利奇纳早期分化，随后生物地理“纵横交错”的谱系从内华达山脉到海岸山脉，回到内华达山脉，然后回到海岸山脉。在内华达山脉和海岸山脉，远亲亲缘血统基本上不会出现在同族中。 CCA 揭示，在海岸山脉和内华达山脉，遥远的系统发育亲属进化出了趋同的形态。我们的证据表明，卡利奇纳的扩散显然受到限制，其古老的生物地理历史为了解加州自古近纪中期以来复杂的地质演化提供了独特的见解。 (C) 2016 Elsevier Inc. 保留所有权利。
The harvestmen genus Calicina is represented by 25 short-range endemic species occurring in the western Sierra Nevada, Transverse and Coast Ranges of California. Our principal aim was to reconstruct the temporal and spatial biogeographic history of this arachnid lineage. We inferred a time-calibrated species tree for 21 of 25 described Calicina species using multiple genes and multilocus coalescent-based methods. This species tree was used as a framework for algorithmic biogeographic and divergence time analyses, and a phylogenetic canonical correlation analysis (CCA) was used to examine the relationship between morphological evolution and environmental variables. Species tree and biogeographic analyses indicate that high-elevation Sierran taxa are early-diverging in Calicina, with subsequent biogeographic "criss-crossing" of lineages from the Sierra Nevada to the Coast Ranges, back to the Sierra Nevada, then back to Coast Ranges. In both the Sierra Nevada and Coast Ranges, distantly-related parapatric lineages essentially never occur in sympatry. CCA reveals that in both the Coast Ranges and the Sierra Nevada, distant phylogenetic relatives evolve convergent morphologies. Our evidence shows that Calicina is clearly dispersal-limited, with an ancient biogeographic history that provides unique insight into the complex geologic evolution of California since the mid-Paleogene.
