Abstract excerpt

Marine predators often function as sentinel species, the first organisms to be impacted when a habitat is disturbed, and directly contribute to ecosystem health by maintaining physical connections between distal habitats. Elasmobranch fishes (sharks and rays) are common predators in most aquatic systems, but over the past 50 years, elasmobranch abundance has dropped >70% from overfishing and climate change....
