Individual shark trajectory patterns and movement speeds were highly variable. Results indicate that Epaulette sharks may be more mobile during diurnal low tides than previously thought. The approach presented here allows the movements and behaviours of marine vertebrates to be analysed at resolutions not previously possible without complex and expensive acoustic arrays. This method would be useful to assess the habitat use and behaviours of sharks and rays in shallow water environments, where they are most likely to interact with humans.]]> Tue 03 Sep 2019 17:58:05 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52631 4). After lipid extraction, significant increases in δ15N values (0.5‰–1.4‰) were found in shark muscle and liver tissues. For pinniped skin samples, δ15N values were not significantly lower after lipid extraction (−0.4‰ to –0.1‰). Conclusions: Lipid extraction did not have a strong impact on δ34S values of shark muscle and pinniped skin (≤1‰). However, our results suggest it is essential to consider the effects of lipid extraction when interpreting results from δ34S values of shark liver tissue, as they significantly depleted values relative to bulk tissue (~5‰). This may reflect selective removal of sulfolipids and glutathione present in higher concentrations in the liver than in muscle and skin and requires further investigation.]]> Thu 19 Oct 2023 15:12:53 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44452 Thu 13 Oct 2022 15:05:26 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40445 Sphyrna mokarran). Both methods indicated similar geographic ranges and suggested that S. mokarran recorded in south-eastern Australia are likely to be from more northern Australian waters. These approaches could be replicated in other areas where coastlines span predictable geographic gradients in isotope values and be used to determine the core population geography of highly mobile species to inform management decisions.]]> Fri 22 Jul 2022 14:37:03 AEST ]]>
