• Trophic structure and food resources of epipelagic and mesopelagic fishes in the North Pacific Subtropical Gyre ecosystem inferred from nitrogen isotopic compositions (2015, background): “scale reductions in the abundance of large, high trophiclevel fishes such as marlins, sharks, and tunas, have been accompanied by increases in nontarget mesopelagic fish species such as gempylids and alepisaurids (Polovina et al. 2009; Polovina and Woodworth-Jefcoats 2013).”
• Movements and habitat use of satellite-tagged false killer whales around the main Hawaiian Islands (2010, background): “…odontocetes in Hawaiian waters (e.g. spinner dolphins Stenella longirostris and common bot- 115 Endang Species Res 10: 107–121 tlenose dolphins Tursiops truncatus; Norris et al. 1994, Baird et al. 2009), tagged individuals were an average of almost 12 km offshore in 575 m of water (Table 4).”
• Does selective fishing conserve community biodiversity? Predictions from a length-based multispecies model (2011, background): “For example, changes in food webs have followed the depletion of apex predators (Polovina et al. 2009), intermediate consumers (Bundy et al. 2009), whales (Springer et al. 2003) and forage fish (Hjermann et al. 2004).”
• Tracking seabirds to identify potential Marine Protected Areas in the tropical western Indian Ocean (2012, background): “Therefore, because fisheries-induced mortality of top predatory fish may lead to a release of epipelagic fauna (see for instance Polovina et al., 2009), it might be expected that industrial fishing would benefit seabirds.”
• The importance of research and public opinion to conservation management of sharks and rays: a synthesis (2011, unknown): “…exerts top-down effects on CSIRO 2011 10.1071/MF11086 1323-1650/11/060518 ecosystems (Carlson 2007), and their loss or decline may have important direct and indirect effects on populations (Heithaus et al. 2008; Polovina et al. 2009) that can cascade through marine ecosystems (Baum and Worm 2009).”
• Diets of five important predatory mesopelagic fishes of the central North Pacific (2013, background): “…longline fisheries operating in offshore waters of the North Pacific Subtropical Gyre (NPSG) regularly harvest several species of tunas and billfishes, along with numerous non-target species of large pelagic fishes such as gempylids and alepisaurids (Boggs & Ito 1993, Polovina et al. 2009).”
