Salinity Tolerance Data - Gastropods

Salinity tolerance data for oyster drills (gastropods). Each row is an individual animal and each column is a variable. "species" refers to Urosalpinx (Atlantic oyster drill) and Ocenebra (Japanese oyster drill). "salinity" is the exposure salinity in practical salinity units. "duration" is the length of exposure in days. "size" is the shell height in millimeters. "alive" is whether or not the animal survived the salinity exposure. "survival" is a numerical code for "alive" where 1 = alive and 0 = death.

本数据集为牡蛎钻螺（腹足类，gastropods）的耐盐性实验数据。数据集每行对应一只个体动物，每列代表一项观测变量。其中，"species"（物种）字段涵盖大西洋牡蛎钻螺（Urosalpinx）与日本牡蛎钻螺（Ocenebra）两个类群；"salinity"（盐度）为实验暴露时的盐度，单位为实用盐度单位（practical salinity units）；"duration"（暴露时长）为盐度暴露的持续天数；"size"（个体大小）为以毫米为单位的个体壳高；"alive"（存活状态）用于表征该个体是否在盐度暴露实验中存活；"survival"（存活编码）为"alive"的数值化编码规则，其中1代表存活，0代表死亡。
