• BIODIVERSITY RESEARCH: Fidelity to foraging sites, consistency of migration routes and habitat modulation of home range by sea turtles (2010, background): “Both male and female sea turtles spend extended periods of time at foraging sites which increases their vulnerability to fisheries bycatch (Lewison et al., 2004; Casale et al., 2008).”
• Individual responses of seabirds to commercial fisheries revealed using GPS tracking, stable isotopes and vessel monitoring systems (2010, background): “Yet despite the evidence that both bycatch and fishery waste can alter the population dynamics and community structure of large marine predators (Lewison et al. 2004; Votier et al. 2004b; c), surprisingly little is known about the ecology of scavenging.”
• Modeling habitat and bycatch risk for dugongs in Sabah, Malaysia (2014, neutral): “Even with these substantial knowledge gaps, interaction with fisheries is considered the single greatest threat to marine megafaunal populations (see Lewison et al. 2004, Read 2008, Grech et al. 2011, Reeves et al. 2013).”
• Behavioural drivers of the ecological roles and importance of marine mammals (2015, background): “…megafauna is becoming increasingly crucial in light of both historical and ongoing anthropogenic changes to both their populations and those of their prey and predators (e.g. Lewison et al. 2004, Estes 2006, Read et al. 2006, Heithaus et al. 2008, 2010, Ferretti et al. 2010, Roman et al. 2014).”
• The global extent and character of marine mammal consumption by humans: 1970-2009 (2011, background): “In contrast, capture of smaller marine mammals in fishing gear has increased in many coastal regions and is now regarded as perhaps the greatest threat to whales, dolphins, and porpoises (Lewison et al., 2004; Read, 2008).”
• Biodiversity and extinction (2007, neutral): “The first are long-distance migrants breeding in temperate regions (Terborgh, 1989; Holmes and Sherry, 2001; Faaborg, 2002; Lloyd-Evans and Atwood, 2004; Sanderson et al., 2006; G.H. Thomas et al., 2006).”
• Environmental DNA (eDNA) as a tool for assessing fish biomass: A review of approaches and future considerations for resource surveys (2021, background): “In addition to concerns over the future sustainability of the world's harvested stocks are the impacts to populations of bycatch species, particularly endangered, threatened, and protected (ETP) species (Gray & Kennelly, 2018; Lewison et al., 2004).”
• Thermal niche, large‐scale movements and implications of climate change for a critically endangered marine vertebrate (2006, background): “For example, leatherback turtle by-catch in a range of fisheries poses a significant threat to population growth and persistence (Lewison et al., 2004a, b) but can be limited by taking into account the habitat preferences of the turtles and by fishing in colder waters, i.e. o20 1C or better still…”
• Plastic and marine turtles: a review and call for research (2016, background): “Additionally, plastic ingestion may impact health and weaken the turtle’s physical condition which could impair the ability to avoid predators and survive anthropogenic threats, such as ship strikes and incidental capture by fisheries, issues which already threaten many marine turtle populations (Le”
• Leatherback, Dermochelys coriacea, Nesting Along the Atlantic Coast of Africa (2007, background): “Conservation efforts have primarily focused on reducing this threat; however, impacts at sea from incidental take in various fisheries remain largely unquantified and may be linked to the decline of certain sea turtle populations (Lewison et al. 2004).”
• New paradigms for supporting the resilience of marine ecosystems. (2005, background): “In its narrowest sense, ecosystembased management extends the focus of resource management beyond target species to include the impacts of fishing on non-target species (caught as bycatch) or the effects of fishing gear on benthic habitats [29, 30 ].”
• Impacts of fisheries bycatch on marine turtle populations worldwide: toward conservation and research priorities (2013, background): “…acute bycatch problems (e.g., Peckham et al. 2007, Alfaro-Shigueto et al. 2011), the relative magnitude of bycatch at broad scales (e.g., Lewison et al. 2004a, b, 2005, Read et al. 2006, Casale 2010, Wallace et al. 2010a), and the need for development and implementation of bycatch…”
• Marine megafauna interactions with small-scale fisheries in the southwestern Indian Ocean: a review of status and challenges for research and management (2018, background): “Fisheries are widely considered the greatest threat to vulnerable marine megafauna (Dulvy et al. 2014; Lewison et al. 2004; Read et al. 2006; Wallace et al. 2010).”
