Long-term temporal trends in gastrointestinal parasite infection in wild Soay sheep

Data associated with "Long-term temporal trends in gastrointestinal parasite infection in wild Soay sheep", published in the journal Parasitology. Data consist of samples collected from individuals in the Augusts of 1988-2018 and the prevalence and abundance of different parasites: fec (strongyles), foc (coccidia), nematodirus, trichuris, capillaria, and moniezia. The suffic "-prev" indicates that this is a variable indicating the presence or absence of a given parasite. The "anthelmintic" variable is a binary variable stating whether or not an animal had been treated with an anthelmintic in the 12 months prior to sample collection.

SOAY SHEEP PROJECT DATA REUSE:
The attached file(s) contain data derived from the long term field project monitoring individual Soay sheep on St Kilda and their environment. This is a request to please let us know if you use them. Several people have spent the best part of their careers collecting the data. If you plan to analyse the data, there are a number of reasons why it would be very helpful if you could contact Dan Nussey ([e-mail]) before doing so.

[NB. If you are interested in analysing the detailed project data in any depth you may find it helpful to have our full relational database rather than the file(s) available here. If so, then we have a simple process for bringing you onto the project as a collaborator.]

1) The data can be subject to change due to updates in the pedigree, merging of records, occasional errors and so on.
2) The data are complex and workers who do not know the study system may benefit from advice when interpreting it.
3) At any one time a number of people within the existing project collaboration are analysing data from this project. Someone else may already be conducting the analysis you have in mind and it is desirable to prevent duplication of effort.
4) In order to maintain funding for the project(s), every few years we have to write proposals for original analyses to funding agencies. It is therefore very helpful for those running the project to know what data analyses are in progress.
5) Individual identifiers may vary relative to other data archives from papers using the individual-level data.

本数据集关联发表于《Parasitology》期刊的学术论文《野生索艾羊胃肠道寄生虫感染的长期时间趋势》。数据集涵盖1988年至2018年各8月采集的个体样本，以及各类寄生虫的感染率与感染负荷：fec（圆线虫类，strongyles）、foc（球虫类，coccidia）、nematodirus（毛圆线虫属）、trichuris（鞭虫属）、capillaria（毛细线虫属）以及moniezia（莫尼茨绦虫属）。变量后缀'-prev'用于指示该变量对应寄生虫的感染状态（阳性或阴性）。'anthelmintic'（驱虫药物）变量为二分类变量，用于指示样本采集前12个月内受试个体是否接受过驱虫治疗。

索艾羊项目数据复用须知：
附件中的数据集源自针对圣基尔达岛（St Kilda）野生索艾羊个体及其生存环境的长期野外监测项目。恳请使用者在使用本数据时告知项目团队——数十年来，诸多科研工作者耗费了职业生涯的大部分时光采集这些原始数据。
若您计划对本数据集开展分析工作，建议您在启动分析前联系Dan Nussey（邮箱：[e-mail]），此举将为项目团队提供极大便利。

【备注】若您希望深入分析项目的完整细节数据，建议获取我们的全量关系型数据库，而非此处提供的文件。若有此需求，我们可通过简便流程邀请您以合作者身份加入本项目。

1. 由于谱系更新、记录合并及偶发数据错误等因素，本数据集可能发生变更。
2. 本数据集结构复杂，不熟悉本研究系统的研究者在解读数据时，可咨询项目团队以获取专业指导。
3. 当前项目合作团队内已有多名研究者正在开展本项目相关数据的分析工作，您计划开展的分析可能已有他人在进行，为避免重复劳动，建议提前与项目团队沟通。
4. 为维持项目的资助支持，我们每隔数年需向资助机构提交原创性数据分析提案。因此，若能提前告知项目团队您正在进行的数据分析内容，将有助于项目的持续运营与发展。
5. 本数据集的个体标识符与其他使用个体水平数据的论文数据存档可能存在差异，请注意区分使用。
