Phenotypic_size_trends_final

This file corresponds to the analyses of long-term phenotypic trends in Daphnia pulicaria. Status specifies whether Bythotrephes is present (Invaded) or absent (Uninvaded) from a lake. The time period is either before (Pre-invasion) or after (Post-invasion) invasions. The lake and year in which sampling was performed are also specified. AL = Allequash, BM = Big Muskellunge, CB = Crystal Bog, FI = Fish, ME = Mendota, MO = Monona, TB = Trout Bog. Sampling was performed by the North Temperate Lakes LTER. All data are available at: https://lter.limnology.wisc.edu/.

本数据集针对长刺溞（Daphnia pulicaria）的长期表型趋势开展分析。其中，Status字段用于标识湖泊中是否存在贝氏溞（Bythotrephes）：存在时标记为「已入侵（Invaded）」，不存在时标记为「未入侵（Uninvaded）」。采样时段分为入侵前（Pre-invasion）与入侵后（Post-invasion）两类，数据集同时记录了采样所在湖泊及采样年份。湖泊缩写与全称的对应关系如下：AL=阿勒夸什湖（Allequash）、BM=大北美狗鱼湖（Big Muskellunge）、CB=水晶沼泽湖（Crystal Bog）、FI=菲什湖（Fish）、ME=门多塔湖（Mendota）、MO=莫诺纳湖（Monona）、TB=特劳特沼泽湖（Trout Bog）。本数据集的采样工作由北温带湖泊长期生态研究站（North Temperate Lakes LTER）完成，全部数据可通过以下网址获取：https://lter.limnology.wisc.edu/。
