Data from: Infection dynamics in coexisting sexual and asexual populations: support the Red Queen hypothesis

Long-term field data from Vergara et al: Infection dynamics in coexisting sexual and asexual populations: support the Red Queen hypothesis. Column headings: "year" gives year of sample; "site" gives the location of the study site at Lake Alexandrina, New Zealand; "gender" gives male or female; "Microphallus" gives infection status: 1 = infected with Microphallus, 2 = not infected with Microphallus; "ploidy" gives reproductive strategy: sexual = diploid; asexual = triploid.Vergara等人的长期野外数据集：聚焦共存有性与无性种群的感染动态研究——支持红皇后假说（Red Queen hypothesis）。该数据集的列字段含义如下："year"表示样本采集年份；"site"表示新西兰亚历山德里纳湖研究样地的具体位置；"gender"标注个体性别为雄性或雌性；"Microphallus（微茎吸虫属）"表示感染状态：取值1为感染微茎吸虫属寄生虫，取值2为未感染该寄生虫；"ploidy（倍性）"对应繁殖策略：有性繁殖对应二倍体，无性繁殖对应三倍体。
