Feeding in the platypus Ornithorhynchus anatinus was investigated by identifying material found in the cheek pouches of animals trapped in nets in a study area on the upper Shoalhaven River, N.S.W. Benthic samples were taken in the rapids and pools of the river and the relative abundance of food items available was related to the food found in the platypus cheek pouches. The main food organisms found were insect larvae, notably Trichoptera, Diptera, Coleoptera, Ephemeroptera and Odonata… Expand
The productivity of the macroinvertebrate prey of the platypus in the upper Shoalhaven River, New South Wales
In the upper Shoalhaven River, New South Wales, macroinvertebrate production was estimated from benthic samples and recorded platypus diet (2009 only) and Rank correlation indicated that the most productive taxa were those most likely to occur in the cheek pouches. Expand
Trophic relationships of the platypus: insights from stable isotope and cheek pouch dietary analyses
It is found that platypuses were feeding on a wide range of benthic invertebrates, particularly insect larvae, and the potential for contribution of the soft-bodied organisms such as larval dipterans is suggested by stable isotope analysis, indicating that the use of both techniques will be important in future ecological investigations.

Effect of food availability and habitat on the distribution of platypus (Ornithorhynchus anatinus) foraging activity
This radio-tracking study aimed to determine whether the spatial distribution of platypus foraging activity varied in relation to habitat attributes and/or the amount of food present along a southern Victorian stream. Expand
Diet of the Australian bass, Macquaria novemaculeata (Perciformes : Percichthyidae), in the Sydney Basin
Season and habitat type had significant effects on composition of the diet of Australian bass, and Insects were the most important food type, followed by fish and large crustaceans, which is a euryphagic carnivore. Expand
Diet and dietary selectivity of the platypus in relation to season, sex and macroinvertebrate assemblages
The diet of platypus Ornithorhynchus anatinus was studied by examination of material collected from the cheek pouches of animals captured while foraging in streams in Kangaroo Valley, NSW, Australia, suggesting that some dietary selectivity is seasonal. Expand
Seasonal changes in food selection and nutrition of captive platypuses (Ornithorhynchus anatinus)
It is concluded that the platypus diet is influenced by nutrition and seasonal factors as well as by prey behaviour, which will contribute to improving the husbandry and management of platypuses, which are widely recognised as difficult to maintain in captivity. Expand
The diving behaviour of the platypus (Ornithorhynchus anatinus) in waters with different trophic status
In the foraging areas with greatest nutrient content and food availability platypus covered longer distances during dives and on the surface, and no substantial effect of depth on TUW. Expand
Effect of flow on platypus (Ornithorhynchus anatinus) reproduction and related population processes in the upper Shoalhaven River
The relationships identified in the study between flow and reproduction also appear to apply to platypus populations occupying urban streams in Victoria, suggesting that they may be widely relevant to this species. Expand
Habitat use by platypus (Ornithorhynchus anatinus) in a modified Australian Wet Tropics catchment, north-eastern Queensland
The habitat affiliations of platypus were investigated in the upper Barron River and its tributaries, a modified Wet Tropics catchment in north-eastern Queensland, Australia, in what is believed to be the first investigation of the influence of human-induced habitat modification on Platypus affiliations in an Australian Wet Tropic river system.

Distribution and characteristics of the platypus (Ornithorhynchus anatinus) in the Murrumbidgee catchment
A baseline that provides a starting point from which the impacts of environmental disturbances or diseases occurring over time can be measured and investigated is established. Expand


The Ecology of the Eastern Water Rat Hydromys Chrysogaster at Griffith, N.s.w.: Food and Feeding Habits.
The eastern water rat, Hydromys chrysogaster, lives in inland waters, estuaries, sea beaches and islands from Queensland to South Australia and Tasmania. It is adapted to semiaquatic life and changesExpand
The biology of a landlocked form of the normally catadromous salmoniform fish Galaxias maculatus (Jenyns). V. Composition of the diet
This landlocked galaxiid was found to share most of the available food resources with the other four fish species found in the lake, and can be broadly classified as a euryphagic carnivore. Expand
The work on which this paper is based began as a study of the food of fresh-water stickleback, but it also became possible to study thefood of roach from the stream in which most of the sticklebacks were collected, and so to examine theFood of an entire community of fishes. Expand
Temperature Regulation in the Platypus, Ornithorhynchus anatinus: Maintenance of Body Temperature in Air and Water
Although platypus spend short periods feeding in captivity, they do spend up to several hours at a time foraging for food in the wild, so temperatures being lower than those recorded in captive animals, especially in winter are thought to account for this. Expand
Waterfowl in an inland swamp in New South Wales. 2. Food.
The food of nine species of waterfowl has been studied in a drought refuge during a period of moderately severe drought, finding that the black swan had certain food plants in common with most other species, particularly during periods of drought, and the grey teal had nearly identical food requirements.

Energy requirements of the dasyurid marsupial mouse Antechinus swainsonii (Waterhouse).
The requirements of the marsupial "mouse" Antechinus swainsonii for energy and water have been investigated using five individuals and it is found that among eutherian mammals,Antechinus most closely resembles the short-tailed shrew Blarina brevicauda. Expand
The organization of the sensory and motor areas of cerebral cortex in the platypus (Ornithorhynchus anatinus)
The organization of sensory and motor regions of the cerebral cortex has been studied in the platypus and a large single area of somatosensory representation in the posterior region of the hemisphere was found. Expand
