Our paper with Luis-Miguel Chevin on the partitioning of variance of reaction norm for plastic traits has now been published in @PeerCommunityJournal.

If you wonder what additive genetic variance could mean in the context of a plastic trait in a heterogeneous environment, and how to estimate it, go check it out!
This has been a long time in the work, and we realised quite a few things ourselves doing it!
