Data from: Transgenerational selection driven by divergent ecological impacts of hybridizing lineages

Ecosystem variables at the end of Phase IAbundance and size of planktonic and benthic prey, and abundance of primary producers, surveyed in 50 mesocosms at the end of Phase I (occupation by adult stickleback from 2 lineages and at 2 densities).Benthic invertebrate stable isotope valuesSI values are for individual invertebrates sampled at the end of Phase I except for Zebra mussels and prosobranch snails, for which each sample is an assay of 3 pooled individuals.Juvenile fish stable isotope valuesStable isotope values for individual juvenile fish sampled at the end of Phase II (muscle tissue).Juvenile fish survival for each mesocosmTotal surviving juveniles of each type (Constance, Geneva, and F1 Hybrids).Juvenile fish condition from mesocosmsBody condition for all mesocosm juveniles, calculated as residuals from a length-weight regression and standardized to weight of a fish of average length.Juvenile fish condition from lab experimentBody condition for all lab experiment juveniles, calculated as residuals from a length-weight regression and standardized to weight of a fish of average length.

第一阶段结束时的生态系统变量：浮游与底栖猎物的丰度、个体大小，以及初级生产者的丰度。该数据采集自第一阶段结束时对50个中型实验生态系（mesocosms）的调查结果，此时实验装置内有两个谱系的成年棘鱼，且设置了两种种群密度。

底栖无脊椎动物稳定同位素值：除斑马贻贝和前鳃类蜗牛外，其余稳定同位素值均来自第一阶段结束时采集的单个无脊椎动物个体；针对斑马贻贝与前鳃类蜗牛，每个样本为3个个体混合后的检测结果。

幼鱼稳定同位素值：幼鱼稳定同位素数据采自第二阶段结束时采集的个体肌肉组织。

各中型实验生态系的幼鱼存活率：统计各类型幼鱼（康斯坦茨品系、日内瓦品系以及F1杂交品系）的存活总数量。

中型实验生态系幼鱼身体状况：针对所有中型实验生态系中的幼鱼，通过体长-体重回归的残差计算其身体状况，并标准化至平均体长个体的体重。

实验室实验幼鱼身体状况：针对所有实验室实验中的幼鱼，同样通过体长-体重回归的残差计算其身体状况，并标准化至平均体长个体的体重。
