INTRODUCTION
Seagrasses are recognized as important habitat-
modifying or facilitator species because they create
spatially complex structure, enhance supply and reten-
tion of propagules, and increase resource supply for a
variety of associated species (Bruno & Bertness 2001,
Williams & Heck 2001). Their facilitator status is tem-
pered, however, by the fact that seagrass meadows
have suffered dramatic declines worldwide during the
past 25 years through a combination of natural and
anthropogenic deterioration (Short & Wyllie-Echever-
ria 1996, Hemminga & Duarte 2000, Green & Short
2003). Effective management of threatened seagrass
populations requires population genetic information
with regard to dispersal, genetic neighborhood size
and diversity (Reusch 2001a).
All seagrass species reproduce sexually through
