Are there patterns behind allocation to clonal offspring?

Curtis Lubbe, Institute of Botany of the Czech Academy of Sciences, discusses their article: Trade-offs and bet-hedging in clonal offspring allocation What about clones? Most angiosperms reproduce clonally in addition to the production of seeds. That is, they form new units of their bodies (rooting units, or ramets): vegetative clonal reproduction, using rhizomes (horizontal belowground stems)…

Cover stories (112:12): Selection favours high spread & asymmetry of flower opening dates within plant individuals

Johan Ehrlén tell us the story behind the cover image for our December issue: This photo, taken in southern Sweden early May, shows inflorescences of Lathyrus vernus. Flowers at the bottom of the inflorescences have already started to wilt and changed colour from purple to light blue, while the uppermost flowers have just opened. This…

Cover stories (112:10): Using machine learning to link climate, phylogeny & leaf area

Cover stories (111:04): The shape of autumn

The cover image for our April issue shows dried, freshly senesced leaves and foliated twigs of different gymnosperm and angiosperm species, demonstrating the size and shape of leaf litter particles.
