自19世纪以来，北美哺乳动物的两个区域已经被确认，在墨西哥重叠。新北区对应于北方区，新热带区对应于南方区。根据特有性的标准，这些地区最近没有区域化。在本研究中，我们整合了两种方法来区域化北美，使用哺乳动物的物种分布模型：特有性分析（EA）和特有性的简约性分析（PAE）。EA被用来获得地方特有的领域和PAE被用来分级。我们发现76个共识区从329套分类在146个分支图，和严格的共识分支图显示了一个基础的多分支与14个地区和16个分支。最后的区域划分承认两个区域（新北区和新热带区）和一个过渡区（墨西哥过渡区），六个次区域（加拿大，阿勒格尼，加利福尼亚-落基山脉，太平洋中美洲，墨西哥湾-中美洲和中美洲），两个地区（加利福尼亚和落基山脉）和23个省。我们的分析表明，北美可能比以前假设的更复杂。(c)2013年，伦敦林奈学会，林奈学会生物学杂志，2013年，110，485-499。
Since the 19th Century, two regions have been recognized for North American mammals, which overlap in Mexico. The Nearctic region corresponds to the northern areas and the Neotropical region corresponds to the southern ones. There are no recent regionalizations for these regions under the criterion of endemism. In the present study, we integrate two methods to regionalize North America, using species distribution models of mammals: endemicity analysis (EA) and parsimony analysis of endemicity (PAE). EA was used to obtain areas of endemism and PAE was used to hierarchize them. We found 76 consensus areas from 329 sets classified in 146 cladograms, and the strict consensus cladogram shows a basal polytomy with 14 areas and 16 clades. The final regionalization recognizes two regions (Nearctic and Neotropical) and a transition zone (Mexican Transition Zone), six subregions (Canadian, Alleghanian, Californian-Rocky Mountain, Pacific Central America, Mexican Gulf-Central America, and Central America), two dominions (Californian and Rocky Mountain), and 23 provinces. Our analysis show that North America is probably more complex than previously assumed.(c) 2013 The Linnean Society of London, Biological Journal of the Linnean Society, 2013, 110, 485-499.
