Data from: Shaped by the past, acting in the present: transgenerational plasticity of anti-predatory traits

Phenotypic expression can be altered by direct perception of environmental cues (within-generation phenotypic plasticity) and by the environmental cues experienced by previous generations (transgenerational plasticity). Few studies, however, have investigated how the characteristics of phenotypic traits affect their propensity to exhibit plasticity within and across generations. We tested whether plasticity differed within and across generations between morphological and behavioral anti-predator traits of Physa acuta, a freshwater snail. We reared 18 maternal lineages of P. acuta...

Data from: Geographic extent of introgression in Sebastes mentella and its effect on genetic population structure

Genetic population structure is often used to identify management units in exploited species, but the extent of genetic differentiation may be inflated by geographic variation in the level of hybridization between species. We identify the genetic population structure of Sebastes mentella and investigate possible introgression within the genus by analyzing 13 microsatellites in 2,562 redfish specimens sampled throughout the North Atlantic. The data support an historical divergence between the “shallow” and “deep” groups, beyond the...
