A. A. Shabanalian naidid fauna consists mostly of cosmopolitan species, although there are indications of greater endemicity than currently recognised. While some naidids are widespread in Australia, others have a northern or a southern bias to their distribution, but few have been recorded in Tasmania. Many new

From 1998 to 2000, 18 adult lake trout (mean fork length 553 mm) implanted with acoustic transmitters (battery life 2 years) were manually tracked. For evening fall locations within the erosive zone of the lake (determined using an existing se

The Finite-Element Method,s the finite-element method has been widely used in the dynamic analysis of large-scale structural systems. The finite-element method is a numerical approach that can be used to obtain approximate solutions to a large class of engineering problems. In particular, the finite-element method is well suited for problems with complex geometries.
