Excited to share that our special issue "Ecological epigenetics at the intersection of behaviour and life history variation in non-model animals", will be coming out in about a week. It's been great to co-edit it with @markravinet.bsky.social @keesvanoers.bsky.social &J.Martínez-Padilla. Stay tuned!
