Jul 28, 2018 · Thalassia, the most abundant seagrass in the area, was the only overlap in the diets of the two species. However, the overlap would presumably have been greater in the same area at a time of seagrass dieback in the 1970s when dugongs consumed relatively more Enhalus (see Nietschmann 1984).

Abstract. Dugongs (Dugong dugon) are listed as vulnerable to extinction due to rapid population reductions caused in part by loss of seagrass feeding meadows.Understanding dugong feeding behaviour in tropical Australia, where the majority of dugongs live, will assist conservation strategies.
Dugongs use two major feeding techniques, viz. cropping ... Enhalus sp.29, Thalassia hemprichii, Syringodium isoetifolium11 and Cymodocea serrulata11,28. -and .
May 21, 2007 · The hypothesis that male dugongs use their tusks in extracting rhizomes from the bottom was tested by examining mouth or stomach samples from dugongs that had been feeding on Thalassia. Johnstone and Hudson reported analyses of such mouth samples from Daru, southern Papua New Guinea. These samples are now stored at James Cook University of ...
This chapter explores the relationship between dugongs and their seagrass habitats in Australian waters. Australia is the dugong’s stronghold (Marsh et al. 2002, 2011) and the dugong’s winter range extends across the northern half of the continent from Shark Bay in the west to Moreton Bay in the east and down to Newcastle in summer (Fig. 19.1).
