Lake Corangamite Analysis - confirm
In the next decades few people spared a thought for the abandoned CAC Wirraway aircraft - one of built at Fishermans Bend for air force training - which became submerged until drought exposed it in But Rodney Knights, a salvage diver and aviation enthusiast, says he is now weeks away from pulling the wreck from the lake after a year quest to retrieve it. An Australian-made Wirraway. The eight-metre-long craft is nearly a kilometre offshore and its extraction is a unique challenge for heritage and aviation buffs.

Items recovered from carcasses or from rescued animals that were unlikely to have survived without human intervention included elastic hair-ties, fishing line, a hospital identification wristband, an engine gasket and a plastic ring seal from a food jar; all of these items had cut Corangamkte skin and Lake Corangamite Analysis most cases deeply into underlying tissue.

A high proportion of the items entangling marine wildlife are fabricated from plastic Gall and Thompsonalthough other materials can also be problematic, e.
The harm caused to vertebrates through entanglement in waste plastic and other synthetic materials also extends to freshwater species Ryan The platypus Ornithorhynchus anatinus is an amphibious inhabitant of reliable freshwater systems in Tasmania including King Island and the southeastern and eastern Australian mainland from approximately the western border of Victoria to as far north as Cooktown, Queensland, with a small introduced population on Kangaroo Island Grant Animals feed exclusively in the water on insects and other macroinvertebrates e. McLachlan-Troup et al. Foraging preferentially occurs at a depth of around 1—3 m in lakes and rivers, Lake Corangamite Analysis sometimes to a depth of nearly 9 m Bethge et al.
A platypus will also find food in shallower water bodies by zig-zagging back and forth along riffles and searching beneath undercut or densely vegetated creek banks Serena There are numerous well-documented cases of a platypus becoming entangled in rubbish looped tightly around its neck or torso; although some items appear to be relatively innocuous, others cause serious injuries or death Serena and Williams The platypus presumably finds it problematic to remove entangling litter at least partly due to the Lake Corangamite Analysis structure of its front feet, which terminate in a broad expanse of skin that unfurls in the water to serve as a paddle comprising A platypus therefore grooms using its hind feet, which are unlikely to Analysis Phaedrus Literary able to remove loops by pulling them forward past the head.
Introduction
A platypus study conducted from to near Melbourne found that We report here on findings from a much larger data set derived from platypus live-trapping studies along with ad hoc mortality Croangamite. We also address the following questions. How does urbanisation affect the frequency of platypus entanglement in anthropogenic materials?]
