文献中很少讨论地方性地区的概念，尽管最近使用的确定方法有所增加。我们介绍了一个基于网格的协议划定AoE使用替代标准的认可AoE的经验测试与收割机物种分布在大西洋雨林。我们的数据，包括778记录的123种，进行了分析，使用简约分析的特有性和特有性分析四个不同的网格（两个细胞大小和两个细胞的位置）。此外，我们采用了六个定性的综合标准来划分AoE，并将其应用于新协议中的数值分析结果，以客观地划分AoE。划定了12个AoE（迄今为止对大西洋雨林最详细的划界），部分证实了文献中先前建立的主要划分。基于网格的方法获得的结果是矛盾的，并受到人为因素的困扰，可能是由于在一个单元中存在不同的特有模式，或由于地理障碍设置倾斜的纬度和经度轴，例如。因此，不应该单独考虑它们发现的一致模式;物种和分支分布的质量特征以及非生物因素应该一起评估。山坡地是特有种的主要分布区，大河流域是主要分布区。避难所，海侵和构造活动似乎在大西洋雨林的演变中发挥了重要作用。(C)2015年的Willi Hennig Society。
The concept of areas of endemism (AoEs) has rarely been discussed in the literature, even though the use of methods to ascertain them has recently increased. We introduce a grid-based protocol for delimiting AoEs using alternative criteria for the recognition of AoEs that are empirically tested with harvestmen species distributions in the Atlantic Rain Forest. Our data, comprising 778 records of 123 species, were analysed using parsimony analysis of endemicity and endemicity analysis on four different grids (two cell sizes and two cell placements). Additionally, we employed six qualitative combined criteria for the delimitation of AoEs and applied them to the results of the numerical analyses in a new protocol to objectively delimit AoEs. Twelve AoEs (the most detailed delimitation of the Atlantic Rain Forest so far) were delimited, partially corroborating the main divisions previously established in the literature. The results obtained with the grid-based methods were contradictory and were plagued by artefacts, probably due to the existence of different endemism patterns in one cell or to a biogeographical barrier set obliquely to latitudinal and longitudinal axes, for example. Consequently, the congruence patterns found by them should not be considered alone; qualitative characteristics of species and clade distributions and abiotic factors should be evaluated together. Mountain slopes are the main regions of endemism, and large river valleys are the main divisions. Refuges, marine transgressions and tectonic activity seem to have played an important role in the evolution of the Atlantic Rain Forest. (C) The Willi Hennig Society 2015.
