Seagrass distribution and seasonal biomass changes in relation to dugong grazing in the Moluccas, East Indonesia.
Aquatic Botany 50(1): 1-19. 2 tabs. 14 figs.
–Studies of a seagrass bed at Ambon dominated by Halodule uninervis, and of biomass removal and recovery in natural and artificial dugong feeding tracks, indicated that the dugongs seemed to be maximizing their intake of rhizomes with high levels of total organic carbon, and therefore maximizing their net rate of energy intake.

Aerial survey of the dugong (Dugong dugon Müller, 1776) in coastal waters of the Lease Islands, East Indonesia.

–Surveys in 1990 and 1992, totaling 3.5 hours of observation, sighted 5-11 dugongs per survey hour and resulted in a minimum population estimate of 22-37 animals, presumably part of a larger regional population.

Observations on the behaviour of the dugong (Dugong dugon Müller, 1776) from waters of the Lease Islands, eastern Indonesia.
Contributions to Zoology (Amsterdam) 67(1): 71-77. 2 tabs. 2 figs.
–French summ. Describes feeding behavior (including ?cultivation grazing of Halophila ovalis, foraging in rough water, making multiple feeding tracks per dive, and possibly eating lingulid brachiopods and Sipunculus sp.); diving times and behavior, including longer dives in deeper water (up to 10 m); and responses to boats and divers.
