Abstract

Increasingly our awareness of seagrass conservation issues requires an understanding of population dynamics and knowledge of the ability of different species to recover from disturbance. Seagrass populations may recover vegetatively or through the establishment of sexually derived seedlings. Some understanding of the processes of population formation and maintenance can be obtained through population genetic surveys. With the advent of molecular genetic markers even genetically depauperate populations can be studied. Patterns of genetic variation can vary over the range of seagrass populations and with the type of marker used. A case study is presented which demonstrates the importance of surveying a significant range of species to better understand the patterns of genetic diversity present. Seagrass phylogeny needs to be improved before reliable taxonomic interpretations can be made in many seagrass groups. Uncommon or rare seagrass species require special attention to ascertain their evolutionary origins and the nature of their extant distributions. Studies of genetic factors may enhance our understanding of how seagrass populations survive over both short and long time scales and can provide considerable insight to the seagrass conservation strategist.
