In stomach contents of 530 dingoes (Canis familiaris dingo) in south east Australia, 89.3% of feed, by occurrence, was large and medium-sized marsupials (Wallabia, Macropus, Pseudocheirus and Trichosurus). Of 26 dingoes with sheep or cattle remains in the stomach, 11 had eaten it as carrion, judging from the presence of maggots, and 5 of those had obtained it from carcasses used as bait for the traps. There was 4% of feral pig, 0.3% of horse and 7.8% of rabbit, which are all regarded as pests. There were 26 species of prey altogether. Of the 25 other species caught in the traps, over 20 were protected wildlife.

The foraging niches of seabirds are driven by a variety of factors, including competition for prey that promotes divergence in trophic niches. Bass Strait, south-eastern Australia, is a key region for seabirds, with little penguins Eudyptula minor, short-tailed shearwaters Ardenna tenuirostris, fairy prions Pachyptila turtur and common diving-petrels Pelecanoides urinatrix being particularly abundant in the region. The trophic niches of these species were investigated using isotopic values in whole blood and by identifying prey remains in stomach contents. The four species occupied different isotopic niches that varied among years, seasons and regions. Little penguins consumed mainly fish whereas the three procellariforms primarily consumed coastal krill Nyctiphanes australis. The dietary similarities between the procellariforms suggest that food resources are segregated in other ways, with interspecific differences in isotope niches possibly reflecting differential consumption of key prey, divergent foraging locations and depth, and differences in breeding phenology. Because oceanographic changes predicted to occur due to climate change may result in reduced coastal krill availability, adversely affecting these seabird predators, further information on foraging zones and feeding behaviour of small procellariform species is needed to elucidate more fully the segregation of foraging niches, the capacity of seabirds to adapt to climate change and the potential for interspecific competition in the region.

South Eastern Australia

Dingoes Canis familiaris dingo, dogs C.J: familiaris, and their hybrids were classified on skull morphology as the following percentages in remote, inland Australia: 97.5,O.1 and 2.4; and in settled south-eastern Australia as 55.3, 10.8 and 33.92%. Canonical analyses of 1184 skulls from the former area and 407 from the latter indicate that mixed populations can be expected wherever close human settlement exists and wild canids remain, but that hybrids are rare in remote regions. The skulls were collected variously between 1966 and 1979; 15 equations were used to allow for differential damage to skulls. The levels of hybridization indicated by the skulls were confirmed by coat colours. The accepted colours for dingoes, (ginger, black-and-tan, and all white) were in the following percentages in inland Australia: 88.6, 3.8 and 1.9; in south-eastern Australia they were 45.9, 19.1 and 0.2%. Broken colorations, ginger with white, black or bluish patches, all black, brown or bluish, black and white, and brindle stripes, were also more numerous in the latter region (34 8%) than in the former (5.7%). Many of these variations arose in cross-breeding experiments with ginger dingoes and variously coloured domestic dogs. Historical reports recorded black dingoes but did not mention tan coloration. That may have been an oversight; if not, it may be a further indication of cross-breeding. The incidence of coat colours was not significantly different in classified dingoes, dogs and hybrids in south-eastern Australia, but ginger coats were less common in classified dogs. Those taxa and the various colorations were not more numerous near farmland than elsewhere in the forests there. A new, basic calibrating equation incorporating the length rather than the volume of auditory bulla is presented. The equation corrects also for mis-measurement of one skull variable in some of the calibrating series of dingoes. Corrigenda are presented. They do not change the general conclusions of the earlier Parts I and II of this series, but wild dingoes raised from pups in captivity did not develop foreshortened snouts as indicated earlier. The possibility remains that some may have developed wider maxillae than wild dingoes.

Stomach contents were analysed to investigate the diets of 52 commercial species of fish. Fish were collected from Bass Strait and adjacent Victorian waters, south-eastern Australia; samples effectively covered the whole of the Victorian coast. Particular emphasis was placed on estimating the importance of arrow squid, Nototodarus gouldri in the diets of the species investigated. For most of the species investigated, the major food items (expressed as the proportion of stomach contents by number, weight and volume or through the calculation of the Index of Relative Importance) were fish or crustaceans. Cephalopods were found in the diets of 21 species but provided a major proportion of the stomach contents in only six species. Arrow squid did not appear to be a major item in the diets of any of the species investigated. For those species that eat large amounts of cephalopods, it appears to be octopus, rather than squid, that is of most significance in the diet.

The diet and feeding ecology of the demersal merlucciid M. novaezelandiae from three areas of the upper continental slope (420-550 m) of south-eastern Australia are described. The food consists almost entirely of mesopelagic fauna. The major prey are myctophid fish Lampanyctodes hectoris, other fishes, natant decapods, euphausiids and squid. Energy values of major prey items were determined by bomb calorimetry. Although euphausiids occur frequently in the diet, fish make up 90% of the energy intake. There is little regional variation. M. novaezelandiae undertakes diel vertical migrations that are similar to those of its prey, bringing it within 50 m of the surface at night. There is a seasonal trend towards cannibalism by adults on juveniles.
