Does physiological integration enable Elymus athericus to colonize an unsuitable habitat?
The grass Elymus athericus is spreading in Wadden Sea salt marshes and outcompetes species-rich communities. We would like to investigate whether Elymus is able to invade apparently unsuitable habitats, because the mother plant is supporting daughter ramets via physiological integration through the rhizome. This will be done in a greenhouse experiment at the University of Hamburg. Plants from the island Schiermonnikoog were provided by co-supervisor Dr. Chris Smit (RUG).
Installing the experiment in the greenhouse (see Fig.), recording morphological and physiological plant parameters, 15N-labelling, measuring 15N-signature in plant material (mass-spectrometer).
