Both species are bottom-feeding carnivores that consumed mainly benthic crustaceans, but teleosts were also abundant in the diet of larger L. vanessa. Non-metric multidimensional scaling (nMDS) ordination and analysis of similarity (ANOSIM) of dietary data revealed significant inter-specific dietary differences; i.e. food resource partitioning. Carbon (δ¹³C) and nitrogen (δ¹⁵N) stable isotope values were similar between L. mulhalli and L. vanessa, however, suggesting similar trophic positioning. Ontogenetic changes in diet composition and stable isotope values were evident. As L. vanessa grew, they preyed upon larger individuals, such as teleosts and caridean shrmips, but no such trend was observed in the diets of L. mulhalli. Adults of both species were significantly enriched in ¹⁵N relative to juvenile conspecifics thus supporting these data. Consequently, in this study, both methodologies, i.e. stomach content and stable isotope analyses, provided evidence of inter- and/or intra-specific dietary segregations and trophic niche partitioning between co-occurring L. mulhalli and L. vanessa off Tasmanian waters.]]> Wed 04 Sep 2019 09:56:13 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:44300 Tue 11 Oct 2022 16:05:32 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39471 15N, δ¹³C and δ³⁴S) to stable isotope signatures in juvenile bull sharks (Carcharhinus leucas) up to 6.5 years post parturition. We found that maternal provisioning was detectable for up to 3.5 years after birth in muscle but only detectable in young-of-the-year for liver. Inclusion of sulphur revealed when maternal signatures disappeared from low-turnover tissue, while also identifying the spatial and trophic ecology patterns from fast-turnover tissue. These results reveal the importance of sampling fast turnover tissues to study the trophic ecology of juvenile elasmobranchs, and how the use of only δ¹⁵N and δ¹³C isotopes is likely to make maternal patterns more difficult to detect.]]> Thu 09 Jun 2022 09:43:28 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50608 Mon 31 Jul 2023 12:50:46 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51902 Fri 22 Sep 2023 09:29:56 AEST ]]>
