Migratory marine species: their status, threats and conservation management needs (2014, background): “For example the recent rapid declines of shark populations owing to overexploitation by fisheries have been shown to induce cascading ecosystem changes, such as mesopredator release (Ferretti et al., 2010; Heithaus et al., 2012).”
Extinction risk and conservation of the world’s sharks and rays (2013, background): “DOI: 10.7554/eLife.00590 2 of 34 Research article”
Global catches, exploitation rates, and rebuilding options for sharks (2013, background): “Time series data suggest that wider community rearrangements often follow declines in shark populations [1] and that the removal of largebodied coastal sharks that prey upon other large-bodied taxa are likely to have cascading consequences for highly productive coastal ecosystems that support other ”
Behavioural drivers of the ecological roles and importance of marine mammals (2015, background): “…267–281, 2015 viduals that continue to forage in shallow habitats during periods of high risk avoid foraging over the interior of seagrass meadows (ca. 80% of the total seagrass area) relative to safer bank edges (Heithaus & Dill 2006, Wirsing et al. 2007a, see Heithaus et al. 2012 for a review).”
Apparent Resource Partitioning and Trophic Structure of Large-Bodied Marine Predators in a Relatively Pristine Seagrass Ecosystem (2013, background): “The shark fauna is dominated numerically by tiger sharks Galeocerdo cuvier (Heithaus 2001b, Wirsing et al. 2006), which account for >90% of captures of sharks over 1.5 m total length (Heithaus et al. 2012).”
Overfishing drives over one-third of all sharks and rays toward a global extinction crisis. (2021, unknown): “It has survived at least five mass extinctions in its 420 million year history(14,15) and has radiated throughout the major marine (and some freshwater) habitats, dominating upper trophic levels and imposing predation risk in many food webs.(16,17) Chondrichthyans are one of the first major marine f”
