Quantifying the role of microphytobenthos in temperate intertidal ecosystems using optical remote sensng
This thesis aimed to quantify the functional and structuring role of MPB on estuarine tidal flats in the estuarine ecosystem. A genetic method was developed to retrieve MPB primary production rates from a combination of remotely sensed information, that allows the assessment of MPB on the estuary scale, ambient temperature measurements, field measurements of photosynthetic parameters and a tide model (Chapter 2), Furthermore, spatio temporal variability in MPB biomass was studie in relation to tidal flat type, salinity and ecotopes using remotely sensed information (Chapter 5). The importance of MPB in the diet of macrofauna was compared to other available food sources and it was investigated how the diet composition of macrofauna may vary spatially, i.e. as function of elevation and estuary. In addtion, the extent to which spatial variation in MPB production in spring may be uses as proxy for macrofaunal grazing in summer/autumn was tested (Chapter 3). The effect of macrofaunal presence on the total biomass and spatial variability of MPB was studied under varying hydrodynamic condition (Chapter 4).
