Vital rate estimates for the common eider Somateria mollissima, a data-rich exemplar of the seaduck tribe

This database contains estimates of the following vital rates (as required
to parameterise matrix population models), for the common eider (Somateria
mollissima): 1st year survival (measured either from hatching, or from
fledging, to 1 year old); 2nd year survival; adult annual survival; first
breeding (both age-specific recruitment probability, and breeding
propensity across potential recruitment ages); breeding propensity of
established female breeders; clutch size; hatching success; and fledging
success. These estimates are drawn from 134 studies, across the scientific
and grey literature – including three previously inaccessible datasets on
clutch size that were contributed in response to a call for data through
the IUCN Species Survival Commission’s Duck Specialist Group (IDs 127, A
and B). This is a relational database, linking estimates and associated
metadata to the relevant study (or unique unpublished combination thereof)
by a unique ID number in the 'MASTER' sheet. For further
information, refer to the associated publication, and/or explanatory notes
on the column headings of each sheet (.xlsx version only, but provided in
the dataset README .txt file).

本数据库包含普通绒鸭（Somateria mollissima）构建矩阵种群模型（matrix population models）所需的以下生命率（vital rates）估算值：1年生存活率（测量时段涵盖从孵化或出飞至1周岁）；2年生存活率；成体年存活率；首次繁殖相关指标（包括年龄特异性补充概率（age-specific recruitment probability），以及潜在补充年龄区间内的繁殖倾向（breeding propensity））；已定居雌性繁殖个体的繁殖倾向；窝卵数（clutch size）；孵化成功率（hatching success）；以及出飞成功率（fledging success）。这些估算值源自科学文献与灰色文献（grey literature）中的134项研究，其中包含3份此前难以获取的窝卵数数据集，这些数据集是通过国际自然保护联盟（IUCN）物种生存委员会鸭类专家组发起的数据征集活动提交的（编号为127、A与B）。本数据库属于关系型数据库（relational database），通过"MASTER"工作表中的唯一标识码，将各项估算值及其关联元数据（metadata）与对应研究（或其未公开的独特组合）进行关联。如需进一步信息，请参阅相关发表文献，以及/或各工作表列标题的说明注释（仅.xlsx版本包含该注释，且相关注释已在数据集的README .txt文件中提供）。
