Lake Mendota, Wisconsin, USA, Zebra Mussel Body Size and Biomass Biometrics 2018

We sampled 98 individuals of the zebra mussel (Dreissena polymorpha) population of Lake Mendota from many littoral zone sites in 2018 to create biometric relationships between several metrics of body size and several metrics of biomass, including length, width, height, living weight, wet weight, dry weight, shell weight, shell-free dry weight, and ash-free dry weight. We selected individuals to span a wide range of body sizes and found strong relationships between most combinations of body size and biomass metrics.

2018年，我们从门多塔湖（Lake Mendota）的多个湖滨带（littoral zone）采样位点采集了98尾斑马贻贝（Dreissena polymorpha）种群个体，旨在构建多种体型指标与多种生物量指标间的生物计量关系，涉及的指标包括体长（length）、体宽（width）、体高（height）、活体重量（living weight）、湿重（wet weight）、干重（dry weight）、壳重（shell weight）、去壳干重（shell-free dry weight）及无灰干重（ash-free dry weight）。本研究选取了覆盖广泛体型范围的个体，最终发现多数体型指标与生物量指标的组合之间存在显著的相关关系。
