1999

Growth of seagrass Halophila ovalis at dugong trails compared to existing within-patch variation in a Thailand intertidal flat.
Mar. Ecol. Progr. Ser. 184: 97-103. 2 tabs. 4 figs. July 28, 1999.
—Reports induction of adaptive morphological plasticity (e.g., in rhizome branching frequency and internode length) of Halophila in dugong feeding trails within 7-10 days. Growth and productivity did not show an increase on this short a time scale; but production rate was nonetheless great enough (7.5 g dry weight per square meter per day) to revegetate trails in less than 10 days, and much greater than a dugong's estimated daily consumption rate (ca. 0.06 g dry weight per square meter per day).
