One of my favorite studies from my dissertation work with Alison Bell at the University of Illinois is out! In this study, we assessed how stickleback offspring integrate cues about predation risk from their fathers, their personal experience, and when both cues were in agreement. While we expected to find evidence of additivity in phenotypes, we were surprised to find remarkable concordance among phenotypes at molecular, morphological, and behavioral levels. These findings have fascinating implications for the evolution of developmental pathways that integrate information in organisms and how plasticity may play a role in evolutionary patterns.
"Personal and transgenerational cues are nonadditive at the phenotypic and molecular level" can be found here.

Remarkable concordance among differentially expressed genes shared among developmental plasticity, transgenerational plasticity, and both.
