Demography of the red alga Chondrus crispus

Abstract: The red alga Chondrus crispus is commonly distributed along the North Atlantic coast. Due to its commercial interest it has been widely studied, however mainly on tidal coasts. Several studies have shown that the haploid stage (gametophyte) is more abundant than the diploid stage (tetrasporophyte). Skewed ratios of life cycle stages are due to differences between stages in adult, juvenile and/or spore survival but so far no thorough demographical study have been performed. The aim of this project is to estimate the vital rates of different stages of Chondrus crispus and model the demography using matrix population models. Furthermore, the effect of factors, such as grazing, on the survival of spores and juvenile stages will be studied by field and laboratory experiments.
