Model Selection of Shark Attack Case
Size Does Matter: Model Selection of Shark Attack Case Andri Wibowo ABSTRACT: Shark unprovoked attacks consist of fatal and non-fatal cases. Numerous cases have been reported involving shark species from Carcharhinus melanopterus with length of 145.5 cm to half-ton Carcharodon carcharias. Currently there are more (P < 0.05) unprovoked non-fatal cases with the average is

Wound-healing capabilities of whale sharks
Wound-healing capabilities of whale sharks (Rhincodon typus) and implications for conservation management Freya Womersley, James Hancock, Cameron T Perry, David Rowat ABSTRACT: Wound healing is important for marine taxa such as elasmobranchs, which can incur a range of natural and anthropogenic wounds throughout their life history. There is evidence that this group shows a high

Boosted regression tree models predict the diets of juvenile bull sharks
Boosted regression tree models predict the diets of juvenile bull sharks in a subtropical estuary Emy Cottrant, Philip Matich, Mark R. Fisher ABSTRACT: Understanding diet flexibility is important for resource management as climate change alters ecological communities. However, food web complexity often limits our ability to predict how changes in prey communities may alter predator
