The status and conservation of dugongs in the Arabian region.
MEPA Coastal & Marine Management Series (Meteorological & Environmental Protection Administration, Saudi Arabia), Rept. No. 10, Vol. 1: xix + 200. 33 tabs. 34 figs. 18 photos. 11 appendices. Jan. 1989.
–Arabic summ. Vol. 2: Preen et al. (1989). Describes the environments of the Arabian Gulf and Red Sea; describes the methods and results of aerial surveys, interview surveys, carcass salvage, radiotracking, and seagrass surveys undertaken on both coasts of Saudi Arabia and adjacent countries; presents measurements of skulls from the Arabian Gulf and compares them with Indian and Australian samples, concluding that the Gulf population may be genetically isolated; discusses the traditional significance, present distribution and abundance, and environmental determinants of status and biology of dugongs in the Arabian region; and outlines human-related threats to dugongs in the region. Dugongs are no longer hunted, but are frequently taken in gill nets and other fishing gear, and are seriously threatened by oil pollution and habitat destruction. The estimated Arabian Gulf population is 7310 ± 1300, making this the most important dugong area known outside Australia. Dugongs occur mainly in the southern and western Gulf, and are probably limited in distribution by low winter temperatures. The estimated Red Sea population is up to 4000 (both coasts), with a patchy distribution. The estimated sustainable mortality may suffice to accommodate the accidental catch in the region, but active conservation is still needed.

Observations of mating behavior in dugongs (Dugong dugon).
Mar. Mamm. Sci. 5(4): 382-387. 1 fig. Oct. 1989.
–Describes behaviors related to mating ("splashing", "following", "fighting", and "mounting") observed in dugong herds in Moreton Bay, Queensland, and compares these observations with other published accounts of dugong and manatee sexual behavior. Concludes that dugongs compete more violently for estrous females than do manatees.

Can dugongs survive in Palau?
Biol. Conserv. 72(1): 85-89. 2 tabs. 2 figs.
–An aerial survey of Palau in 1991 found even fewer dugongs per flight-hour than earlier surveys, while interviews indicated that regular poaching continued along with illegal sale of jewellery made from dugong ribs. The authors believe that dugongs will go extinct in Palau unless poaching is stopped immediately.

Response of dugongs to large-scale loss of seagrass from Hervey Bay, Queensland, Australia.
Wildl. Res. 22: 507-519. 5 tabs. 5 figs.
–Following floods and a cyclone in 1992, a massive seagrass die-off resulted in the emigration and/or starvation of most of the Hervey Bay dugong population. Full recovery of this population may take more than 25 years.

Diet of dugongs: are they omnivores?
Jour. Mamm. 76(1): 163-171. 1 tab. Feb. 23, 1995.
–Summ.: BBC Wildlife 13(7): 23, 1 fig., July 1995. Analysis of dugong feces from Moreton Bay, Queensland, showed they had fed deliberately on ascidians and polychaetes in addition to seagrasses. This is attributed to nutritional stress due to seasonal scarcity of seagrasses at this subtropical site.

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.

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.

Marine protected areas and dugong conservation along Australia's Indian Ocean coast.
Envir. Management 22(2): 173-181. 3 tabs. 2 figs. Mar.-Apr. 1998.
–Concludes that the present system of marine protected areas is inadequate, and should incorporate not only ecological representativeness but also the needs of threatened species. Records in passing that at least 14 dugongs died in the 1991 Arabian Gulf War oil spill, and that the scale of occasional movement by dugongs can be on the order of 200 km (176).
