Observation of fruit production by the seagrass Halodule wrightii in the northeastern Gulf of Mexico

摘要

Halodule wrightii is a highly clonal, dioecious seagrass with a wide geographic range. Though sexual reproduction has been observed in other areas of its range, we report here the first documented case of fruit production in the northeastern Gulf of Mexico. We also report on seasonal patterns of growth and biomass allocation in this region and discuss the implications of even occasional sexual reproduction for the population dynamics of this species.
