SNP data: Population genetic structure in bull sharks (Carcharhinus leucas)
<p><span>The bull shark (<em>Carcharhinus leucas</em>) is a large, mobile, circumglobally distributed high trophic level predator that inhabits a variety of remote islands and continental coastal habitats, including freshwater environments. </span>Here, we hypothesise that the barriers to dispersal created by large oceanic expanses and deep-water trenches result in a heterogeneous distribution of the neutral genetic diversity between island bull shark populations compared to populations sampled in continental locations connected through continuous coastlines of continental shelves. <span>We analysed 1,494 high-quality neutral Single Nucleotide Polymorphism (SNP) markers in 215 individual bull sharks from widespread locations across the Indian and Pacific Oceans (South Africa, Indonesia, Western Australia, Papua New Guinea, eastern Australia, New Caledonia and Fiji). Genomic analyses revealed partitioning between remote insular and continental populations, with the Fiji population being genetically different from all other locations sampled (<i>F</i><sub>ST</sub> 0.034-0.044, <i>P </i>< 0.001), and </span>New Caledonia showing marginal isolation (<i>F</i><sub>ST</sub> 0.016-0.024, <i>P </i>< 0.001; albeit based on a small sample size) from most sampled sites<span>.</span> Discriminant Analysis of Principal Components (DAPC) identified samples from Fiji as a distinct cluster with all other sites as one large cluster. Genetic structure analyses (Admixture, STRUCTURE & AssignPOP) further supported the genetic isolation of bull sharks from Fiji, with the analyses in agreement. The observed differentiation in bull sharks from Fiji makes this site of special interest, as it indicates a lack of migration through dispersal across deep-water trenches and large ocean expanses.</p>
Ontogenetic changes in the tooth morphology of bull sharks (Carcharhinus leucas)
<p>Teeth are an integral component of feeding ecology with a clear link between tooth morphology and diet, as without suitable dentition prey cannot be captured nor broken down for consumption. Bull sharks <em>Carcharhinus leucas</em> undergo an ontogenetic niche shift from freshwater to marine habitats, which raises the question: does tooth morphology change with ontogeny? Tooth shape, surface area and thickness were measured using both traditional morphometrics and an Elliptic Fourier Analysis, to determine if morphology varied with position in the jaw and if there was an ontogenetic change concordant with this niche shift. Significant ontogenetic differences in tooth morphology as a function of position in the jaw and shark total length were found, with upper and lower jaws of bull sharks presenting two different tooth morphologies. Tooth shape and thickness fell into two groupings, anterior and posterior, in both the upper and lower jaws. Tooth surface area, however, indicated three groupings, mesial, intermediate and distal, in both the upper and lower jaws. While tooth morphology changed significantly with size, showing an inflexion at sharks of 135 cm total length, each morphological aspect retained the same tooth groupings throughout. These ontogenetic differences in tooth morphologies reflect tooth strength, prey handling and heterodonty.</p>
