| dc.description.abstract | This thesis aims to validate the properties of Betula nana leaf cuticles, to use this specie as palaeo-proxy. The effect of micro-habitats on the stomatal characteristics of B. nana from Abisko, Sweden, will be examined with undulation index (UI), growing degree days (GDD5) and stomatal index (SI). Furthermore the effect of the increasing amount of atmospheric CO2 on the stomatal properties of B. nana will be examined, to test and validate the CO2 responsiveness via stomatal frequency (PL, SD and SI). Also the consequences of CO2 adaptation for the hydrology of the birch species via stomatal conductance (gsmax) will be determined. Conclusion is that the leaces of B. nana can be used as palaeo-proxy, the stomatal characteristics are nog influenced by micro-habitat, and they are in line with other species. | |
