Aquatic snail and macrophyte abundance and richness data for ten lakes in Vilas County, WI, USA, 1987-2020

Data accompanying the paper Szydlowski et al. "Three decades of lake monitoring reveals community recovery after population declines of invasive rusty crayfish (Faxonius rusticus)." Macrophytes and snails were sampled in ten lakes in Vilas County, Wisconsin, USA during summer sampling events in 1987, 2002, 2011, and 2020. Lakes had varying levels of invasion by F. rusticus, which affected measures of macrophytes and snails. Macrophytes were sampled using a point-intercept transect method and snails were sampled using different sampler types which were dependent on substrate. Macrophytes were sampled at 6-14 sites per lake and snails were sampled at 16-31 sites per lake. Overall, this dataset provides abundance and richness data for over 25 species of snails and over 40 species of macrophytes in north temperate lakes.

本数据集配套Szydlowski等人发表的题为"Three decades of lake monitoring reveals community recovery after population declines of invasive rusty crayfish (Faxonius rusticus)"的研究论文。该研究于1987、2002、2011及2020年的夏季采样季，对美国威斯康星州维拉斯县的10个湖泊中的大型水生植物（macrophytes）与螺类（snails）开展了采样工作。上述湖泊受到锈色螯虾（Faxonius rusticus）不同程度的入侵，该入侵物种对大型水生植物和螺类的群落监测指标造成了影响。大型水生植物采用样点截线法（point-intercept transect method）进行采样，螺类则根据底质类型选用适配的采样工具。每个湖泊的大型水生植物采样点数量为6至14个，螺类采样点数量为16至31个。总体而言，本数据集涵盖了北温带湖泊中25种以上螺类与40种以上大型水生植物的丰度及物种丰富度数据。
