..., rock scrambling and/ or swimming through the canyon streams. The sport's popularity is reported to have increased substantially over time, causing concern for the sustainability of these fragile ecosystems. To investigate visitor impacts, benthic macroinvertebrate assemblages and water quality were...

...Danial Stratford; Gordon Grigg; Hamish McCallum; Harry Hines The breeding ecology and phenology of two sympatric stream breeding myobatrachid frogs were studied across a breeding season in a stream at Cunningham's Gap, south-east Queensland. Mixophyes fleayi is listed as endangered and M...

... in first order headwater streams. The main trapping sites were in twenty first order streams, eight second-fourth order headwater streams and one fifth order stream reach. Additional trapping was also undertaken in the South Esk River and farm dams. Sites were trapped during late spring/mid summer...

... breeding behaviours of the southern subspecies, H. a. flavopunctatus , including amplexus and spawning, breeding microhabitat, and associated environmental conditions at a site in East Gippsland. Frogs were observed breeding in an ephemeral second-order stream following heavy rainfall, with oviposition...

...David Hunter; Graeme Gillespie A survey was conducted of the distribution and abundance of stream-breeding frogs within Kosciuszko National Park, with particular emphasis upon locating new populations of the endangered Spotted Tree Frog Litoria spenceri. Twenty-five streams were sampled within...

..., propelled from the foot of the floating female onto a near-vertical or overhanging stream bank (Ovipositional Process 1). In M. balbus and M. fleayi eggs are deposited aquatically in the shallow riffle zones of small streams, either into a rounded nest depression in the substrate (Ovipositional Process 2A...

... of Australia. In contrast to L. aurea most declines affected species occurring at high altitude with relatively restricted ranges. These species typically bred in streams, adults were closely associated with stream habitats, and anthropogenic impacts such as habitat destruction, pollution or introduced...

... pellets. We recorded more pellets: (1) in 30 and 80 year old forest that remained unburned in fires that occurred in 2009, (2) on sites within closed National Parks relative to sites in State Forest, and (3) close to streams. introduced herbivore Mountain ash forest faecal pellet index Modelling...

... River at Sofala New South Wales. Seven stream reaches were sampled within study areas, and the Boorolong Frog was recorded in four of those. Thirty-four Booroolong Frogs were recorded, by direct observation and call play back, usually in habitat typically associated with the species. Seven of these were...

... movement from Hay. M. peelii peelii showed only minor movements (up to 141 km) up and downstream from Narrandera, with only one long distance movement from Balranald to Gundagai. Net downstream stream movement of M. ambigua declined as one moved downstream closer to the mouth of the Murray River...

... in a botanical garden and the other on a beach. The two dogs adapted their behaviours for the habitat and the particular challenges presented. One dog used waves in a beach environment, which aided concealment and increased its momentum when springing at gulls. The other dog followed a dry ephemeral stream...

... along the waterway. These results add to the understanding of negative impacts of bank disturbance which leads to weed infestation of stream banks. 194 December 2005AustralianZoologist volume 33 (2) Introduction In the aquatic environment there are subtle relationships between plants and animals...

..., and their affluent streams, are suppressing platypus numbers. An experiment indicated that the legal drum nets used in the industry are less of a threat to platypuses than the use of gill nets and the illegal nets used by poachers. Banning of gill nets from the industry and stringent law enforcement would largely...
