Ex situ and in situ data for endangered livestock breeds in Spain

Improvements in ex situ storage of genetic and reproductive materials offer an alternative for endangered livestock breed conservation. This is a dataset for current ex situ collections and in situ population for 179 Spanish livestock breeds of seven species, cattle, sheep, pig, chicken, goat, horse and donkey. Ex situ data was obtained via survey administered to 18 functioning gene banks in Spain and relates to the reproductive genetic materials (semen doses) of 211 livestock breeds distributed across the gene banks. In situ data combines CENSUS information with linear regression techniques and relates to the geographic distribution of 179 Spanish autochthonous livestock breeds (2009-2018), and in situ population projections and extinction probabilities (2019-2060). We use a decision variable defining an “acceptable level of risk” that allows decision makers to specify tolerable levels of in situ breed endangerment when taking ex situ collection and storage decisions.

异位（ex situ）保存遗传与繁殖材料的技术进步，为濒危畜禽品种保护提供了新的可行路径。本数据集涵盖7个物种共179个西班牙本土畜禽品种的现有异位保存资源与原位（in situ）种群信息，涉及物种包括牛、绵羊、猪、鸡、山羊、马与驴。异位保存相关数据通过对西班牙18家运营中的基因库（gene bank）开展调研获取，涵盖分布于各基因库的211个畜禽品种的繁殖遗传材料（精液剂量）信息。原位种群数据则结合普查（CENSUS）信息与线性回归技术，涵盖179个西班牙本土畜禽品种2009年至2018年的地理分布情况，以及2019年至2060年的原位种群预测数据与灭绝概率。本研究采用一个定义"可接受风险水平"的决策变量，可帮助决策者在制定异位收集与保存决策时，明确原位品种濒危程度的可容忍阈值。文件说明：Ex_Situ_In_Situ_Data.xlsx：包含完整的原位与异位保存数据；GenerateFigureCensus.m：用于生成原位种群预测数据的Matlab(R)代码；Economic_Survey.docx：针对西班牙基因库开展的经济成本调研问卷。如需获取更多详细信息，请参阅：https://doi.org/10.1016/j.ecolecon.2020.106916
