North Temperate Lakes LTER Bythotrephes longimanus spiny water flea population monitoring in Wisconsin and Minnesota 2009 - 2014

Three data tables are included describing population dynamics for Bythotrephes longimanus, spiny water flea, in Southern Wisconsin during invasion. General monitor took place in Lake Mendota, Lake Monona, Lake Waubesa, Lake Kegonsa, Stormy Lake, Gile Flowage, Lake Gogebic. Accompanying Bythotrephes morphological measurements from Lake Mendota monitoring efforts in 2011 and 2012. Included are individual measurements of body morphology and reproductive status for ~2,500 Bythotrephes collected from Lake Mendota in 2011 and 2012. Sediment cores from Lake Mendota were analyzed for spiny water flea evidence with age of sediment estimated.本数据集包含三张数据表，用于描述南威斯康星州入侵期间多刺水蚤（Bythotrephes longimanus，英文俗名刺水蚤（spiny water flea））的种群动态。常规监测覆盖门多塔湖（Lake Mendota）、莫诺纳湖（Lake Monona）、瓦贝萨湖（Lake Waubesa）、凯贡萨湖（Lake Kegonsa）、斯托米湖（Stormy Lake）、吉尔滞洪水库（Gile Flowage）以及戈吉比克湖（Lake Gogebic）。数据集附带2011至2012年门多塔湖监测项目中获取的该物种形态学测量数据，其中包含同期从该湖采集的约2500只多刺水蚤的个体形态参数与繁殖状态测量结果。此外，研究人员对门多塔湖的沉积物岩芯开展了分析以检测刺水蚤的遗存证据，并同步估算了沉积物的沉积年代。
