New paper out – Diterpenoid fingerprints in pine foliage across an environmental and chemotypic matrix: Isoabienol content is a key trait differentiating chemotypes

Text by Lauri Laanisto Intraspecific variability in functional traits has emerged in recent years as a quite important phenomenon. At least in plant ecology. Traditional view in life sciences has promoted between-species differences as much more significant drivers of ecological … Continue reading
