Agency in human–shark encounter

Agency in human–shark encounter

Agency in human–shark encounter Leah Gibbs ABSTRACT: Shark bite is exceptionally rare. And yet, representations of human–shark interactions are most often framed as inherently dangerous. The ‘shark attack’ trope has been widely critiqued as sensationalist and misleading. This image creates two further limitations: it offers a one-dimensional representation of sharks and overlooks crucial factors shaping

Diet Composition and Nutritional Niche Breadth Variability in Juvenile White Sharks

Diet Composition and Nutritional Niche Breadth Variability in Juvenile White Sharks (Carcharodon carcharias) Richard Grainger, Victor M. Peddemors, David Raubenheimer, Gabriel E. Machovsky-Capuska ABSTRACT: Establishing diets and dietary generalism in marine top predators is critical for understanding their ecological roles and responses to environmental fluctuations. Nutrition plays a key mediatory role in species-environment interactions, yet
