Paternal effects on seed germination: a barrier to the genetic assimilation of an endemic plant taxon?

abstract：:Recently, two squirrel species (Spermophilus spp.) were discovered to anoint their bodies with rattlesnake scent as a means of concealing their odour from these chemosensory predators. In this study, we tested multiple species with predator scents (rattlesnake and weasel) to determine the prevalence of scent applicati...
