The potential for unmanned aerial vehicles (UAVs) to conduct marine fauna surveys in place of manned aircraft (2018, background): “In many surveys, two sets of observers sit on either side of the aircraft and sight within a predefined transect width (often around 200 m) on each side (Gales et al., 2004; Holley et al., 2006; Hammond et al., 2013).”
On the adaptive benefits of mammal migration (2014, background): “However, there is also suggestive evidence that dugong migratory behavior may be induced by habitat degradation caused by tropical cyclones (Gales et al. 2004).”
Living on the edge: dugongs prefer to forage in microhabitats that allow escape from rather than avoidance of predators (2007, background): “Shark Bay is home to a large population of dugongs (10 000e14 000 individuals; Marsh et al. 1994; Preen et al. 1997; Gales et al. 2004), but their use of our study area fluctuates seasonally (Wirsing et al., in press a).”
A comparison of shark and wolf research reveals similar behavioral responses by prey (2011, background): “In Western Australia’s Shark Bay, where dugongs number between 10 000 and 14 000 (Gales et al. 2004), shallow banks (water depth < 4.”
Aerial surveys and the potential biological removal technique indicate that the Torres Strait dugong fishery is unsustainable (2004, background): “Marsh & Lawler (2001, 2002) and Gales et al. (2004) also explored possible reasons for the temporal differences between population estimates obtained from repeat aerial surveys of the southern Great Barrier Reef and Hervey Bay, the northern Great Barrier Reef and Western Australia, respectively,…”
Long-term movements of tiger sharks satellite-tagged in Shark Bay, Western Australia (2007, background): “The results of the present study do not allow us to test this hypothesis, but we would not expect sharks to move into pelagic waters if they were following dugong movements because dugongs remain largely in coastal waters during their migrations (Gales et al. 2004).”
