Status and distribution of dugongs in Western Australia. In: H. Marsh (ed.), The dugong. Proceedings of a seminar/workshop held at James Cook University of North Queensland 8-13 May 1979 (q.v.).
[Townsville (Australia)], James Cook Univ. (vii + 400): 67-87. 3 tabs. 3 figs.
–Reports results of aerial surveys, describes environmental conditions in Shark Bay, and discusses prospects for dugong conservation in Western Australia, where dugongs are still abundant and relatively undisturbed. Shark Bay is considered to have unrivalled potential as a dugong study site.

Dugong in northern waters of Western Australia 1984.
Dept. of Conservation & Land Management Western Australia, Tech. Rept. No. 7: vi + 38. 6 tabs. 13 figs. Mar. 1986.
–Aerial-survey results show that Exmouth Gulf is an important dugong habitat, but the coastline farther north has only a sparse dugong population that probably cannot sustain the present level of Aboriginal hunting. A traditional method of taking dugongs "by hand" is mentioned but not explained. Also describes and illustrates representative seagrass beds of the region.

The distribution and abundance of the dugong in Shark Bay, Western Australia.
Wildl. Res. 21(2): 149-161. 4 tabs. 4 figs.
–Aerial surveys in winter 1989 gave a minimum population estimate of 10,146ñ1,665 (s.e.) dugongs at an overall density of 0.71ñ0.12 (s.e.) dugongs/kmý, the highest density ever recorded on a large-scale survey. The high proportion of calves (19%) suggested an exceptionally high calving rate in 1988. Dugong density was highest in relatively deep water (12-16 m). Surveys in summer 1990 and 1991 confirmed that dugong distribution in Shark Bay varies seasonally with water temperature.

Elemental composition of a tusk of a dugong, Dugong dugon, from Exmouth, Western Australia.
Mar. Biol. 129(2): 203-214. 5 tabs. 5 figs.
–X-ray fluorescence-imaging and analysis of acid-digested material from a tusk of a 55-year-old pregnant female dugong provided a record of fluctuations in barium, calcium, iron, lithium, magnesium, sodium, phosphorus, strontium, and zinc. These fluctuations are attributed to natural environmental changes and/or changes in the dugong's physiology with increasing age; elements usually regarded as pollutants or as affected by anthropogenic changes were not detected.

Distribution and abundance of dugongs, turtles, dolphins and other megafauna in Shark Bay, Ningaloo Reef and Exmouth Gulf, Western Australia.
Wildl. Res. 24(2): 185-208. 5 tabs. 10 figs.
–Aerial surveys in 1989 and 1994 estimated populations of about 10,000 dugongs at Shark Bay and about 1,000 each at Ningaloo Reef and Exmouth Gulf. Extension of the Shark Bay Marine Park to coincide with the marine section of the Shark Bay World Heritage Area is recommended.
