Restoration of abandoned grassland is an important aspect of sustainable resource investment in conservation areas. Success of restoration varies with the degree and duration of former abandonment as well as with environmental conditions. We use permanent plots on grassland associations that differ in just these aspects and follow the annual changes in plant species comopistion. Such we can make assumptions about the time needed to gain a desired compositional condition of the respective grassland communities.

Stomata are tiny pores on the surface of plant leaves and play a central role in global water and carbon cycles. The pores cover less than 5% of the leaf area but facilitate the majority of the exchange of gases between the atmosphere and terrestrial vegetation. The opening of stomata is adjusted to provide CO2 for photosynthesis and to limit water loss. This process exhibits transient responses under fluctuating environmental conditions. The speed at which stomata respond influences productivity and water use efficiency of both crops and natural ecosystems. Although stomatal responses are a target for crop improvement, we lack a clear description of the process, impeding its complete mechanistic understanding. Novel temporal 3D imaging can address the need for a better description of stomatal movements. By complementing fast high-resolution X-ray microcomputed tomography (µCT) with fluorescence microscopy, we will provide in vivo 3D imaging of variations in epidermal cell size and shape and its effects on stomatal movements, scaling from subcellular to whole leaf traits. To fully harness the high volume of data generated by µCT, we will develop novel computational methods to automatically segment images and track single 3D cells over time. This project will answer long-standing questions about stomatal movements and will generate basic knowledge on how to improve stomatal responses under dynamic environments in order to increase net productivity and water-use efficiency.

GBS is a very useful tool for research on plants and animals. The Poland et al. (2012) protocol is well suited for small- and large-genome taxa as the PstI fragments are less frequent (Truong et al. 2012). No size selection of digested fragments is necessary. By applying GBS, we aim at tracing the dispersal of individuals between populations. The proposed GBS method makes it possible to determine the degree of genetic relationship between individuals and populations and thus to understand gene flow (dispersal of seeds and/or plant fragments) between populations. 'Alpenschwemmlinge' are alpine plants growing in lowland river banks. The main research question is: To what extent are seeds (or plant fragments) swept down from the alpine zone?
