"1. Seed dispersal is of high applied relevance as it governs colonization processes in rare species and during plant invasions," researchers in Berlin, Germany report.
"Seed tracking is a powerful approach to analysing dispersal processes and usually requires seed tagging. Marking diaspores with fluorescent colours is a promising tagging method, but comes with several technical limitations. 2. We analysed the durability of different colours, associated changes in weight gain and lift-off velocity, visibility under ultraviolet (UV) light and recapture rates for different diaspore types (samaras, plumed diaspores and small, round diaspores). 3. Weight gain ranged ...
