Satellite tracking highlights the need for international cooperation in marine turtle management (2006, background): “…abundant marine turtles undoubtedly played a major role in Caribbean marine ecosystems, acting as grazers and consumers (Bjorndal & Jackson 2003, Moran & Bjorndal 2005) and it is therefore presumed that their loss had a drastic impact on the balance of such ecosystems (McClenachan et al. 2006).”
Diversity in trophic interactions of green sea turtles Chelonia mydas on a relatively pristine coastal foraging ground (2011, unknown): “…herbivores, including green sea turtles Chelonia mydas and sirenians, can structure seagrass communities by changing species composition and biomass or short-circuiting detrital cycles (e.g. Thayer & Engel 1982, Bjorndal 1997, Aragones & Marsh 2000, Moran & Bjorndal 2005, Aragones et al. 2006).”
Encouraging outlook for recovery of a once severely exploited marine megaherbivore (2008, methodology): “…the green turtle for maintenance of seagrass and algal ecosystems (including detrital pathways and nutrient recycling) has been well documented using ecosystem mass-balance simulation models (Thayer et al ., 1982; Polovina, 1984) and by manipulative field experiments (Moran & Bjorndal, 2005, 2007).”
The ecological importance of intact top-predator populations: a synthesis of 15 years of research in a seagrass ecosystem (2012, background): “Green turtles may have similar impacts (e.g. Aragones 2000; Aragones andMarsh 2000; Moran and Bjorndal 2005; Lal et al. 2010).”
Marine megaherbivore grazing may increase seagrass tolerance to high nutrient loads (2012, background): “However, the simulated leaf grazing did not decrease seagrass nutrient content compared to ungrazed seagrass, which is in contrast to other studies that described less intense grazing (Moran & Bjorndal 2005, 2007; Aragones et al. 2006; Heck et al. 2006; Fourqurean, Muth & Boyer 2010).”
Herbivory on freshwater and marine macrophytes: A review and perspective (2016, background): “The effects of marine herbivores may include stimulated production of seagrass (Valentine et al., 1997; Moran and Bjorndal, 2005; Vonk et al., 2008b; Christianen et al., 2012), changes in seagrass meadow structure (Lal et al., 2010), and the reduction of the flux of organic matter and nutrients to…”
Past, current and future thermal profiles of green turtle nesting grounds: Implications from climate change (2010, background): “…by climate change is extremely important as green turtles have important ecological roles (e.g. maintenance of seagrass and algal ecosystems) (Moran and Bjorndal, 2005, 2007), social importance to indigenous people (Johannes and Macfarlane, 1991), and value to the tourism industry (Wilson…”
Management strategies to mitigate the impacts of climate change on sea turtle’s terrestrial reproductive phase (2011, unknown): “Sea turtles (Cheloniidae) have important ecological roles (e.g., maintenance of seagrass and algal ecosystems (Thayer et al. 1982; Moran and Bjorndal 2005)), are highly valuable to tourism industries (Clem and Clevo 2001; Wilson and Tisdell 2001), and have great spiritual and social importance to…”
Simulated green turtle grazing affects nutrient composition of the seagrass Thalassia testudinum (2007, background): “Simulated grazing reduced the structural complexity, but not the productivity, of T. testudinum plots ( Moran and Bjorndal 2005 ).”
Hawksbill sea turtles in seagrass pastures: success in a peripheral habitat (2010, background): “Grazing has substantial effects on the structure and nutrient content of T. testudinum pastures ( Moran and Bjorndal 2005, 2007 ).”
Delayed ontogenic dietary shift and high levels of omnivory in green turtles (Chelonia mydas) from the NW coast of Africa (2009, background): “Consumption of animal prey has been considered to increase carrying capacity over that derived from seagrass productivity and turtle intake ( Moran and Bjorndal 2005 ), but the opposite might be true if the availability of highquality animal prey required to match the nutritional requirements of gre”
Extensive direct measurements of Posidonia oceanica defoliation confirm the importance of herbivory in temperate seagrass meadows (2007, background): “Although sea turtles, sirenians and waterfowls are recognized as important seagrass consumers (Preen 1995, Ganter 2000, Moran & Bjorndal 2005), in their absence, herbivory has usually been considered a marginal process in seagrass ecosystems.”
