Premise Of The Study: Pollen dispersal is a key biological process enabling plant populations to maintain genetic connectivity. Direct estimates of pollen dispersal using paternity assignment or correlated paternity estimates require highly variable genetic markers, of which microsatellites are the markers of choice. •
Methods And Results: Eight species-specific microsatellites have been developed for Ranunculus bulbosus, combining classical enrichment methods with 454 sequencing. These markers have been used in paternity analysis as well as in pollen-pool analyses and proven to be highly polymorphic (seven to 63 alleles in the largest population studied). An excess of homozygotes in six loci indicate the presence of null alleles. •
Conclusions: These markers are the first microsatellites isolated and tested on R. bulbosus and provide a useful tool for population genetic studies in this common grassland herb.

Generative processes have been evaluated in six European buttercup species in order to verify the hypothesis that the reproduction efficiency of clonal species is lower than that of nonclonal ones. The study covered common species (, , , , ) and the endangered . The following properties have been assessed: pollen viability (staining method), pollen grain germination and the pollen-tube elongation in pistil tissues (fluorescence microscopy), seed formation efficiency, seed viability (tetrazolium test) and germination ability by introducing factors interrupting dormancy (low temperature and gibberellin application).

The Ranunculus species are poorly known as medicinal plants. They have potential toxicity given by the ranunculin and its enzymatic degradation compounds: protoanemonin and anemonin. This paper aims to evaluate the anemonin content of four species: R.

Clinical Findings: A buttercup plant, Ranunculus bulbosus L, was abundantly present in all pastures and paddocks on the farm. All horses, especially lactating mares and their foals, had mild to severe weight loss as assessed by body condition.

The requirements of the water transport system of small herbaceous species differ considerably from those of woody species. Despite their ecological importance for many biomes, knowledge regarding herb hydraulics remains very limited. We compared key hydraulic features (vulnerability to drought-induced hydraulic decline, pressure-volume relations, onset of cellular damage, in situ variation of water potential, and stomatal conductance) of three Ranunculus species differing in their soil humidity preferences and ecological amplitude.
