Gold Coast Canal system.

<p>Map illustrating the location of the Nerang River (natural habitat) and Broadwater (in black) and adjoining canal systems (artificial habitat) (in white). Green and grey section of main map illustrates the approximate delineation of low (grey) and high (green) saline areas and upper (grey) and lower (green) river and canals. Numbers indicate the locations of longline surveys (LL), acoustic receivers (AR- highlighted in yellow) and conductivity temperature and depth meters (CTD). Lined area indicates freshwater separated from the artificial and natural habitats by a weir and lock.</p

Catch per unit effort (CPUE) (± SE) for quarterly longlines surveys for bull sharks in the Gold Coast System.

Total length and ontogenetic stage of bull sharks in the Gold Coast System.

<p>Mean (±SE) total length (TL) and range of <i>C. leucas</i> of different ontogenetic stages (N = neonate, J = juvenile, SA = subadult, A = adult) caught on rod and line (n = 8), longlines (n = 49) and in gillnets (n = 9) in the upper and lower areas of the Nerang River (natural habitat) and the upper and lower canals (man-made habitat) from January 2006 to December 2008. (RU = river upper, CU = canal upper, RL = river lower, CL = canal lower). Note: rod and line fishing done sporadically across the entire system and gillnets were only deployed in the upper reaches of the Nerang River. Note: A^# = a putatively pregnant female 300 cm TL.</p

Total detections at individual acoustic receivers for all neonate and juvenile bull sharks tagged with acoustic tags in the Gold Coast system.

<p>Numbers on the × axis refer to individual stations (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0049796#pone-0049796-g001" target="_blank">Figure 1</a>) for river (A) and canal (B) habitats. River numbers correspond to upper river on the left to lower river on the right. Upper canal (6 and 7) and lower canal (14 and 12) are shown accordingly. Asterisk denotes stations with<15 detections.</p

Summary of overall movements of bull sharks tagged with acoustic tags in the Gold Coast System.

<p>Movements within or between habitats of river (R) and canal (C) by different ontogenetic stages. N = neonate, J = juvenile. Tagging Habitat, RU = river upper, CU = canal upper, RL = river lower, CL = canal lower, M = male, F = female. # refers to bull sharks captured by recreational fishers.</p

Figure S1 from Population structure and connectivity of tiger sharks (<i>Galeocerdo cuvier</i>) across the Indo-Pacific Ocean basin

Allele frequencies by population comparing <i>G. cuvier</i> sampled in Hawaii (HAW) (this study) and the Central Pacific (CP) (Bernard et al. 2016). Two loci (tgr_348 and tgr_891) could not be reliably correlated between the studies and were therefore excluded
