这是一个协议,用于对来自可涉水溪流和河流的鱼类和无脊椎动物数据的大小谱(个体质量与种群密度之间的缩放关系)进行建模。方法包括:采集定量鱼类和无脊椎动物样品的田间技术;实验室方法标准化现场数据;和统计数据分析。
大小频谱预测丰度作为单个大小的函数。大小光谱研究表明,来自不同生态系统的相对较小的大型生物的丰度具有很强的相似性。与使用物种级别平均尺寸的传统大小丰度缩放关系不同,大小谱模型是 ataxic,可以解释样本中每个人的大小。
演示该程序将是布兰登·格雷维特,莎拉·海利和吉安卡洛·拉卡内利,现场技术人员。确定研究到达的上游和下游端点后,用可移动标记磁带标记末端。测量沿研究范围长度均匀分布的五到十个横口的湿流通道的宽度,并估计研究的总表面积为平均湿润通道宽度乘以到达的总长度。
