...Matthew Mo Surveys of the impact of stem-boring insects were carried out across 14 Flooded Gum Eucalyptus grandis plantations in the New South Wales North Coast bioregion. This paper reports on novel observations made during this work of the Bleating Tree Frog Litoria dentata seeking refuge...

... faecal pellets are a source of nutrients and carbon during flooding in the Macquarie Marshes, an inland floodplain wetland, in south-eastern Australia. The faecal pellets of kangaroos, most likely of Red Kangaroo (M. rufus) , were found on the dry floodplain adjacent to Bora Channel (~30.6433°S...

...S. V. Briggs; S. A. Thornton This study investigated relationships between durations of inundation in River Red Gum wetlands and waterbird breeding, in particular the durations of flooding under nest trees that waterbirds need to breed successfully; and developed guidelines for managing water...

... it to colonise some, but not all, rice-growing areas. One such area, the Coleambally Irrigation Area, presently contains a large proportion of the remaining known locations of the species in New South Wales. Within this area this frog is widespread and locally abundant, and it uses flooded rice fields...

...Monique Webb; Claire Reymond; Ashley Miskelly; Maria Byrne ABSTRACT Echinoderms are highly sensitive to decreased salinity and are vulnerable to mass stranding caused by flood-driven freshwater runoff and high wave conditions from storms. The coast of New South Wales is prone to east coast low (ECL...

... variations in climatic conditions, and the effects of extreme events such as wildfire and flood. The non-endemic yabbie Cherax destructor expanded its distribution since it was initially detected at one site in 2006 and now occurs in the upper laterals of two catchments, having moved above waterfalls...

... in flooded areas of Terara Swamp and Brundee Swamp, while outside the breeding season more frogs were seen in the catchment of Rotten Creek, the largest tributary of Brundee Swamp. Ten of the systematic sites were ponds constructed for the species as offsets for various developments. Breeding activity...

... recaptured a total of 922 times, giving a recovery rate of 19.4%. Residency, migration, irregularity of visits and the influence that rainfall and flooding played on these were examined. Birds banded elsewhere in the Riverina are recorded and the incidence of breeding is reported. The need for long term...

... tadpoles in streams subsequent to flooding – ( M. balbus and M. fleayi ), and mode 18 (terrestrial eggs above water, exotrophic hatchlings move to water ( M. carbinensis , M. coggeri, M. fasciolatus, M. iteratus and M. schevilli ). Mixophyes fasciolatus was the only species to use both lentic as well...

... trenches, 7125 (97%) were found alive and released. Of the 224 dead animals, 29 (13 %) were of two threatened mammal species, most of which drowned in low flooded sections of trenches following rainfall. Nine threatened species were found in trenches, and an additional 5 threatened species were found along...

... within the catchment. Agricultural clearing and urban development have also affected aquatic ecosystems. The pre-European environment was apparently characterized by creek and river systems subjected to periodic floods, but with clear water, low nutrient levels, and clean sandly or rocky substrates...

...L. C. Llewellyn G. rostratus the Murray Jollytail bred in earthen ponds at the Inland Fisheries Research Station, Narrandera, NSW, when surface and bottom water temperatures were above 10.5oC during August and September. Flooding was unnecessary but there was water flow through the pond. Eggs were...

... of small birds, which may have been indicative of the presence of a dense understorey and shrub layer in conjunction with a distinct tree canopy. Overall waterbird abundance and diversity was low due to flood conditions and local rainfall providing ample feeding and nesting areas, thus spreading...

... completely restricted to water bodies that are still, relatively unshaded, and low in salinity (i.e., <7.3 ppt). All of its known breeding sites are highly disturbed,mostly through human activities but also through flooding and other natural processes. It generally breeds in small (i.e., <1000 sq m...

... and three at Urbenville). We found that M. norfolkensis roosted in tree hollows in a range of tree species, including Grey Box Eucalyptus moluccana and Spotted Gum Corymbia maculata in the Hunter Valley and Flooded Gum E. grandis and red gum E. amplifolia / tereticornis in Urbenville. Additionally...

... the clearing of native vegetation, the introduction of farming and grazing, and hydrological alteration. The hydrology of the floodplain wetlands was altered initially by manually-constructed shallow drains but later, and more drastically, by a flood mitigation scheme that involved the construction of deep...

..., flooding, breeding, fish stocking and angler pressure account for different growth rates. Growth curve von Bertalanffy growth curve Macquaria ambigua growth curves Anderson, J.R. 1988. Freshwater Fish. Australian Society for Fish Biology Proceedings No. 8:97. Freshwater Fish Australian...

..., but apparently also for dealing with unpredictable events such as droughts and perhaps fires and floods. As torpor substantially reduces energy requirements its use will in turn reduce the need for foraging and consequently exposure to predators. Predator avoidance by employing torpor and minimising foraging may...

...Jennifer O'Meara; Kerry Darcovich Narawang Wetland, a precinct of Sydney Olympic Park, was constructed to provide habitat for the Green and Golden Bell Frog Litoria aurea . The Plague Minnow Gambusia holbrooki invaded Narawang following flooding soon after the wetland's completion in 2000. Narawang...
