Sedimentary links and the spatial organization of Atlantic salmon (Salmo salar) spawning habitat in a Canadian Shield river

Auteurs :
DAVEY, C.
LAPOINTE, M.

Description :
First, the AA. propose an extension of the sedimentary link concept for lower relief, old mountain landscapes and test its utility along the Ste Marguerite River (SMR), a salmon river draining the Canadian Shield in the Saguenay region of Québec, in which valley-scale deposits of coarse sediment (mostly of Pleistocene age) are important in initiating links. Then they discuss potential sources of minor, sublink scale grain size variability and their effects on how sedimentary links are defined. Lastly, they demonstrate the usefulness of the link structure to model the distribution of Atlantic salmon spawning habitat (a habitat that depends critically on bed texture).
