Correlations of polyploidy, apomixis and alpine environmental gradients

Correlations of polyploidy, apomixis and alpine environmental gradients

In a recent article published in AoB PLANTS, Schinkel et al. present a study on geographical parthenogenesis, an enigmatic and much disputed phenomenon that involves closely related sexual and apomictic (asexually reproducing) taxa displaying largely divergent distribution patterns. Based on a large sampling of natural populations of Ranunculus kuepferi, their study is the first quantitative,…

New on 500px : Blooming in the Alps by monisiri by monisiri It was late spring and the Gardetta Plateau in the Alps Cozie was in full bloom. That evening the weather was very cloudy, but a crack in the clouds illuminated quickly the splendid flowering of buttercups (ranunculus kuepferi). from 500px For download Click Here

Can a cold snap put a stop to sex? Full paper: http://j.mp/2tiFiQz (Open Access) The common name for R. kuepferi is Kuepfer’s buttercup. Its leaves could be mistaken for stalks of grass. It’s flowers are white with a golden centre and sit between 5cm (a couple of inches) to over 30cm (over a foot) above the ground. You’d find it in wet grasslands in the Alps, and that’s the root of a big problem for it. R. kuepferi is used to sitting under a blanket of snow. As the seasons turn the ice thaws, but the weather in the Alps can be changeable. There’s always the possibility of an overnight frost. This is a particular danger to the reproductive parts of a plant, which do not welcome being exposed to a freezing chill.
