Importance of waterborne seed dispersal for conservation of alder-dominated riparian woodlands

Black alder, Alnus glutinosa Gaertn, is the most abundant native tree in Scottish riparian woodlands where it plays a key ecological role. Despite its importance in riparian ecosystem function, the reproduction and dispersal dynamics of the species has been little studied. Seeds are small and equipped with air-filled wings that enable them to float. Long-distance water dispersal of seeds for several km is therefore believed to be driven by flowing water. This project proposes to investigate the relationship between river flow dynamics and and river margin colonisation by alder via waterborne seed dispersal in a river catchment using a landscape genetics approach. Field activities will be based in Scotland; in the river Tay catchment which contains large areas of undisturbed alder dominated floodplain habitat of high nature conservation value. Laboratory activities will involve genotyping of microsatellite markers to detect patterns of seed-mediated gene dispersal. The project will offer scope to develop a geographically-explicit model integrating ecological and genetics data in order to investigate how landscape characteristics, such as fragmentation by dams and flood embankments, affects dispersal distance and connectivity of alder-dominated riparian woodlands and thus inform their conservation management.

The project will require a combination of field work, molecular biology, data analysis and modeling. Individuals with an interest in ecological genetics are encouraged to apply. The successful candidate will join the restoration genetics group in the School of Biological and Environmental Sciences at the University of Stirling.
