Demography of the red alga
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.
