Abstract
Several species assembly mechanisms have been proposed to structure ecological communities. We assess the biogeography of seaweeds along 2,700 km of South Africa's coastline in relation to a thermal gradient produced by the Agulhas Current, and contrast this with the environmental structure created by the Benguela Current. We subdivided the coastline into `bioregions' to examine the regional patterning. To investigate the assembly mechanisms, we decomposed Sorensen's Beta-diversity into `turnover' (Bsim) and `nestedness-resultant' (Bsne) dissimilarities, and used distance-based redundancy analysis (db-RDA) to relate them to the Euclidian thermal difference, dE, ...
