Lake survey 13C benthos

Lakes were sampled using an Eckman grab or from shore to collect invertebrates for 13C analysis. Animals were live sorted from samples, held overnight in filtered lake water, then dried for stable isotope analyses. Analyses were performed and UC Santa Cruz laboratory.

为收集用于13C同位素分析的无脊椎动物，研究人员采用埃克曼采泥器（Eckman grab）或沿岸采样的方式对湖泊开展采样。从采集的样本中活体分选得到动物个体后，将其置于过滤后的湖水中暂养过夜，随后进行干燥处理以开展稳定同位素分析。所有分析工作均在加利福尼亚大学圣克鲁兹分校（UC Santa Cruz）实验室完成。
