Hohokam-Area Faunal Troika Data
收藏资源简介：
This data file includes summary data for an analysis of zooarchaeological abundance at archaeological sites in the Hohokam culture area of the US Southwest. Columns Site: Name of the archaeological site (note that assemblages from different phases or periods within a single site are listed on separate lines). ConsolidatedPeriodCode: Time period of the assemblage, as grouped for the analysis (A=Middle/Late Archaic, B=Early Ceramic/Pioneer/Colonial, C=Sedentary, D=Classic). SiteNum: State of Arizona archaeological site identification number. Lagomorpha: The proportion of lagomorphs out of lagomorphs, artiodactyls, and rodents. Artiodactyla: The proportion of artiodactyls out of lagomorphs, artiodactyls, and rodents. Rodentia: The proportion of artiodactyls out of lagomorphs, artiodactyls, and rodents. TotalNISP: The total number of specimens identified at any taxonomic level, including those outside the classes Lagomorpha, Artiodactyla, and Rodentia. Richness: The count of taxa at the genus level (or higher where no genera are identified within a family or class). Evenness: The inverse of Simpson's Index (Simpson 1949; Hill 1973) for proportions of specimens in the classes Lagomorpha, Artiodactyla, and Rodentia. References Hill, M.O., 1973. Diversity and evenness: a unifying notation and its consequences. Ecology 54:427–432. Simpson, E.H., 1949. Measurement of Diversity. Nature 163:688.
本数据集收录美国西南部霍霍坎文化（Hohokam culture）区域内考古遗址的动物考古丰度分析汇总数据。各字段说明如下： Site：考古遗址名称（注：同一遗址内不同阶段或时期的遗存将单独成行列出）。 ConsolidatedPeriodCode：本次分析分组的遗存所属时期代码（A=中/晚阿恰特期，B=早期陶期/拓殖期/殖民期，C=定居期，D=经典期）。 SiteNum：亚利桑那州官方考古遗址编号。 兔形目（Lagomorpha）：兔形目在兔形目、偶蹄目（Artiodactyla）与啮齿目（Rodentia）类群中的占比。 偶蹄目（Artiodactyla）：偶蹄目在兔形目、偶蹄目与啮齿目类群中的占比。 啮齿目（Rodentia）：偶蹄目在兔形目、偶蹄目与啮齿目类群中的占比。 TotalNISP（总鉴定标本数）：任意分类阶元下的鉴定标本总数，涵盖兔形目、偶蹄目与啮齿目之外的类群标本。 Richness（分类丰富度）：属级分类单元的计数结果；若科或纲下未鉴定到属，则按更高分类阶元统计。 Evenness（均匀度）：针对兔形目、偶蹄目与啮齿目类群的标本占比，采用辛普森多样性指数（Simpson's Index）的倒数形式（Simpson 1949; Hill 1973）。 参考文献： Hill, M.O., 1973. 多样性与均匀度：统一符号及其推论. *Ecology* 54:427–432。 Simpson, E.H., 1949. 多样性的测量. *Nature* 163:688。
