A BALANCED MODEL OF THE FOOD WEB OF THE ROSS SEA, ANTARCTICA (2010, background): “…both directly from by-catches, and indirectly by altering the species composition and inter-specific relationships within the ecosystem through trophic effects, that is, by one species feeding on another (Myers et al., 2007; Daskalov et al., 2007; Heithaus et al., 2008; Casini et al., 2009).”
Lower trophic levels and detrital biomass control the Bay of Biscay continental shelf food web: Implications for ecosystem management (2011, methodology): “Cephalopods.”
Impacts of climate change on marine organisms and ecosystems. (2009, background): “Polar bears are not only struggling in the face of ice loss, but are also weakened by accumulation of polychlorinated biphenyls [114]; the Black Sea suffered a regime shift after prolonged heavy fishing pressure, a jellyfish invasion and eutrophication [130]; many coral reefs are suffering from risi”
Have jellyfish in the Irish Sea benefited from climate change and overfishing? (2011, background): “, 2005) and in the Black Sea, trophic cascades and outbreaks of jellyfish have been reported to have been triggered by overfishing (Daskalov et al., 2007).”
Recruitment failure of coastal predatory fish in the Baltic Sea coincident with an offshore ecosystem regime shift (2010, background): “Large predatory fish have declined on a global scale, generating cascading ecosystem effects in coastal and pelagic marine communities (Estes et al., 1998; Frank et al., 2005; Halpern et al., 2006; Daskalov et al., 2007).”
Cascading top-down effects of changing oceanic predator abundances. (2009, background): “In the Black Sea, pronounced declines in dolphins and piscivorous fishes by the early 1970s led to increased abundance of planktivorous fishes, reduced zooplankton biomass, and a doubling of phytoplankton (Daskalov 2002; Daskalov et al. 2007).”
The jellyfish joyride: causes, consequences and management responses to a more gelatinous future. (2009, background): “Some jellyfish, especially ctenophores, are robust to ballast water exchange, and have often increased in abundance once translocated to new areas where the dominant planktivorous fish in the system has been removed [ 43 ].”
Resolving the effect of climate change on fish populations (2009, background): “Other studies, however, suggest that the dominance of bottom-up control can switch to top-down control, resulting in trophic cascades initiated by overfishing (Worm and Myers, 2003; Frank et al., 2005; Daskalov et al., 2007; Möllmann et al., 2008).”
Spatial correlation as leading indicator of catastrophic shifts (2010, background): “Such critical transitions have been described, among others, for lakes (Scheffer 1998; Carpenter 2005), for marine and coastal environments (Petraitis and Dudgeon 1999; Daskalov et al. 2007), for terrestrial communities (Handa et al.”
Resilience indicators: prospects and limitations for early warnings of regime shifts (2015, background): “Subsequent studies suggested a similar potential of shifting between alternative states (or ‘regimes’) also in coral reefs [4,5], kelp forests [6,7], macroalgae beds [8], fish populations [9–11], and even whole pelagic and benthic communities [12–16].”
