WATERSCAPE
The waterscape is defined as the spatially and temporally dynamic water present on and within the uppermost layer of the Earth, which serves as the interface between the lithosphere, atmosphere, hydrosphere, and biosphere—known as the critical zone. The WATERSCAPE project aims to elucidate how waterscapes contribute to the coexistence of aquatic species.
Diatoms will serve as our model organisms, and the high-mountain waterscape—where theoretical expectations can be empirically tested—will be our model system. Specifically, we aim to demonstrate that the spatial and temporal variability of waterscapes facilitates diatom species coexistence by either equalizing relative fitness or promoting niche differentiation. The project will integrate field observations, field experiments, and laboratory experiments to characterize the growth responses of a large number of diatom species (hundreds) to environmental gradients. Ultimately, this approach will allow us to fit parameters of coexistence theory and investigate the role of different spatial and temporal environmental fluctuations in shaping species distribution patterns across the high-mountain waterscape
