Food Web Isotope Study at North Temperate Lakes LTER 2004 - 2010

Stable isotope ratios (d13C and d15N) were measured in archived scale samples of seven fish species captured in Sparkling Lake over the period 1981 through 2009. Stable isotopes of benthic and pelagic food web end members (macroinvertebrates and zooplankton, respectively) were also measured. Zooplankton were from samples taken in Sparkling Lake, Allequash Lake, and Big Muskellunge Lake. Zoobenthos were from samples taken in Sparkling Lake. Isotope Study abstract paragraph 2 Number of sites: 3本数据集针对1981—2009年采自闪光湖（Sparkling Lake）的7种鱼类存档鳞片样本，测定了其稳定同位素比值（d13C和d15N）。研究同时测定了底栖与浮游食物网的端元稳定同位素，其中底栖食物网端元为大型底栖无脊椎动物，浮游食物网端元为浮游动物。浮游动物样本采自闪光湖、阿勒夸什湖（Allequash Lake）及大马斯卡隆日湖（Big Muskellunge Lake）；底栖动物样本仅采自闪光湖。同位素研究摘要第2段：采样点数量：3个。
