Do life history traits influence patterns of maternal immune elements in New World blackbirds (Icteridae) data release

This metadata record represents passive immunity components of six songbird species (Passeriformes) in a single taxonomic family, the New World blackbirds (Icteridae). Six immune elements were compared among blackbird eggs collected in North Dakota, South Dakota, and Puerto Rico, including immunoglobulins (Ig) in both yolk and albumen, lipopolysaccharide-specific immunoglobulins in both yolk and albumen, and ovotransferrin and lysozyme in albumen. The data were summarized and used in the analysis for a peer-reviewed journal publication entitled: "Do life history traits influence patterns of maternal immune elements in New World blackbirds (Icteridae)?" The data consist of two data sets. The first data set includes day, year, and location (county or municipality, U.S. State or Territory) of egg collection, a species code, a ratio between positive and negative values of immunoglobulin in egg yolk, and a ratio between positive and negative values of lipopolysaccharide-specific immunoglobulins in egg yolk. The second data set includes day, year, and location (county or municipality, U.S. State or Territory) of egg collection, a species code, a ratio between positive and negative values of immunoglobulin in egg albumen, a ratio between positive and negative values of lipopolysaccharide-specific immunoglobulins in egg albumen, concentration of lysozyme (an antimicrobial enzymen) in egg albumen, and concentration of ovotransferrin (an antimicrobial enzymen) in egg albumen. Both data sets also include information on parasitism rates in the northern Great Plains between 1990 to 2015 (L.D. Igl, unpublished data) and average incubation periods for blackbird species from the literature.

本元数据记录涵盖单一分类科——拟鹂科（Icteridae）下6种鸣禽（雀形目，Passeriformes）的被动免疫成分。研究对采自北美达科他州、南达科他州及波多黎各的黑鹂卵中的6种免疫成分开展了比较分析，包括卵黄与卵清中的免疫球蛋白（immunoglobulins, Ig）、卵黄与卵清中的脂多糖（lipopolysaccharide）特异性免疫球蛋白，以及卵清中的卵转铁蛋白（ovotransferrin）与溶菌酶（lysozyme）。本数据集经整理后，用于一篇题为"Do life history traits influence patterns of maternal immune elements in New World blackbirds (Icteridae)?"的同行评议期刊论文的分析工作。本数据集由两个数据集构成：第一个数据集包含卵采集的日期、年份与地点（美国州或领地内的县或自治市）、物种代码、卵黄免疫球蛋白正负值比值，以及卵黄脂多糖特异性免疫球蛋白正负值比值；第二个数据集包含卵采集的日期、年份与地点（美国州或领地内的县或自治市）、物种代码、卵清免疫球蛋白正负值比值、卵清脂多糖特异性免疫球蛋白正负值比值、卵清溶菌酶（一种抗菌酶）浓度，以及卵清卵转铁蛋白（一种抗菌酶）浓度。两个数据集均收录了1990年至2015年大平原北部的寄生率数据（L.D. Igl，未发表数据），以及来自文献的黑鹂物种平均孵化期信息。
