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）的多个沿岸带（littoral zone）采样点采集了98只斑马贻贝（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，其中体型指标涵盖长度、宽度、高度，生物量指标则包括活体重、湿重、干重、壳重、去壳干重及无灰干重。本次选取的样本覆盖了广泛的体型范围，并发现多数体型指标与生物量指标的组合均存在显著相关关系。
