Macroinvertebrate and algae collection data

This dataset contains the information of the sites and carbon and nitrogen isotope information of macroinvertebrates and algae sampled in the streams of Salt Lake Valley, Utah: Red Butte Creek, Emigration Creek, Mill Creek, Big Cottonwood Creek, Logan River, as well as Diamond Creek which is located in northwestern Arizona. The macroinvertebrates were collected by surfer sampler and the algae collected by hand and the sampling occurred from June - September, 2015. The samples were cleaned and prepared within 48 hours for nitrogen and carbon stable isotope analysis in the mass spectrometer at the stable isotope facility, SIRFER. The purpose of the study was to assess the efficacy of the use of nitrogen stable isotope patterns of macroinvertebrates and algae to observe potential anthropogenic impacts in streams that flow from a montane to urban ecosystem gradient.

本数据集收录了犹他州盐湖山谷各溪流（包括红山溪、移民溪、米勒溪、大棉木溪、洛根河以及位于亚利桑那州西北部的钻石溪）中采集的各类无脊椎动物和藻类的信息，以及其碳和氮同位素比数据。无脊椎动物样本由冲浪式采样器收集，藻类样本则通过手工采集，采样时间跨度为2015年6月至9月。样本在48小时内被清洗并制备，以便在SIRFER稳定同位素设施中的质谱仪上进行氮和碳稳定同位素分析。研究旨在评估利用无脊椎动物和藻类的氮稳定同位素模式来观察从山地至城市生态系统梯度中流经的溪流中潜在的人为影响的效能。
