SYNOPSIS
Slower growth and increased mortality are common metabolic costs affiliated with reproduction. In many cases the cost of reproduction in marine algae has been calculated solely based on increased allocation to reproductive tissue and reduced allocation to vegetative tissue. In addition, however, it may be necessary to address whether or not allocation patterns influence a population’s demography by affecting life history traits. Changes in growth patterns could have major effects on the reproductive strategies of an organism, which in turn would significantly impact the demographics of a population.

 

Members of the family Gracilariaceae are some of the most highly cultivated and harvested seaweeds world-wide, providing a valuable economy in at least 19 countries. These algae have very complex life-histories with a suite of methods for propagation, including release of spores, sexual fertilization and vegetative fragmentation. The purpose of my study is to investigate the allocation of resources between growth and reproduction within Gracilariopsis sp. and to measure the effect on the persistence of physically disturbed populations.
