• Permanent 'phase shifts' or reversible declines in coral cover? Lack of recovery of two coral reefs in St. John, US Virgin Islands (2006, background): “Although high macroalgal abundance is sometimes associated with high nutrient input, Szmant (2002) concluded that increases in nutrients are seldom the cause of major increases in algae on coral reefs (see also McCook 1999).”
• Effects of herbivores, nutrient enrichment, and their interactions on macroalgal proliferation and coral growth (2009, background): “However, evidence to date indicates that its influence on tropical coral reefs is limited compared to the effects of overharvesting herbivores (Hughes et al. 1999; Szmant 2002; Burkepile”
• Differential competitive abilities between Caribbean coral species and a brown alga: a year of experiments and a long-term perspective (2006, background): “…over the relative importance of increased nutrients and reduced herbivory in controlling algal communities (Hughes et al. 1999, Lapointe 1999, 2004, Szmant 2002, McClanahan et al. 2004), both factors have been reported to enhance the growth and cover of algae, satisfying both views (e.g. Lapointe…”
• Nutritional status and metabolism of the coral Stylophora subseriata along a eutrophication gradient in Spermonde Archipelago (Indonesia) (2011, background): “Over the last few years, there has been an intense debate about the varying effects of nutrification on corals ( Szmant 2002; Loya and Kramarsky-Winter 2003; Rinkevich et al. 2003).”
• Ratcheting Down the Coral Reefs (2004, background): “There is no evidence that the rate of reef degradation has begun to decrease (Patterson et al. 2002, Szmant 2002, Wilkinson 2002, Buddemeier and Ware 2003, Gardner et al. 2003, Garrison et al. 2003, Lang 2003).”
• Alternative states on coral reefs: beyond coral–macroalgal phase shifts (2009, background): “The loss of key herbivores has been suggested to be the strongest driver, and although nutrient overloads can contribute to reef degradation, they are unlikely to lead to phase shifts unless herbivory is unusually or artificially low (see reviews by McCook 1999, Szmant 2002).”
• Algal contact as a trigger for coral disease (2004, background): “Declining levels of herbivory, increasing supply of nutrients and coral mortality have been suggested as the main factors promoting macroalgal abundance (McCook 1999; Aronson & Pretch 2001; Szmant 2002).”
• Revisiting the catastrophic die-off of the urchin Diadema antillarum on Caribbean coral reefs: Fresh insights on resilience from a simulation model (2006, background): “Such similarities in interaction are not surprising given that nutrification reduces the efficacy of grazing on macroalgal cover and is therefore functionally equivalent to depleting grazer biomass (see Szmant, 2002).”
• Temporal changes in benthic assemblages on Florida Keys reefs 11 years after the 1997/1998 El Niño (2013, background): “The concern that many of the world’s reefs are being overtaken by macroalgae has led resource managers to focus primarily on conserving herbivores and improving water quality (Szmant 2002, Bellwood et al. 2004, Aronson & Precht 2006, Hughes et al. 2007, Bruno et al. 2009).”
• Nutrient enrichment enhances black band disease progression in corals (2006, background): “These short-term reductions in coral growth are likely linked to increased competition for CO2 between calcification and photosynthesis as zooxanthellae densities increase (Szmant 2002).”
• Crustose coralline algae can suppress macroalgal growth and recruitment on Hawaiian coral reefs (2011, unknown): “However, the abundance of algae on reefs (or lack thereof) cannot always be explained by these factors alone (McCook 1999, Szmant 2002, Vroom et al. 2006, Vermeij et al. 2009a, 2010).”
• Nutrient enrichment can increase the severity of coral diseases (2003, background): “The global nitrogen cycle has been dramatically altered over the last 100 years (Vitousek 1994; Nixon 1995).”
