Shift in seagrass food web structure over decades is linked to overfishing (2012, background): “Experiments have demonstrated that enhanced nutrient loading alone has little negative effect on seagrass growth when natural populations of mesoherbivores are present (Duffy & Hay 2000, Hughes et al. 2004, Valentine & Duffy 2006).”
Biodiversity and the functioning of seagrass ecosystems (2006, background): “Similarly, the identity of herbivore taxa is important to ecosystem processes; fishes and sea urchins often injure seagrasses by feeding on them, whereas most gastropods and crustaceans facilitate seagrasses by grazing their competitors (Hughes et al. 2004, Valentine & Duffy 2005).”
Trophic interactions in Zostera marina beds along the Swedish coast (2008, background): “Eutrophication is considered to be one of the main reasons for loss of seagrass (see reviews by Hauxwell et al. 2003, Hughes et al. 2004), because an increased nutrient supply enhances phytoplankton production and turbidity and also promotes the annual rapid growth of filamentous algae and…”
Natural densities of mesograzers fail to limit growth of macroalgae or their epiphytes in a temperate algal bed (2009, background): “Effects of grazing may be evident only during periods of low productivity (Nicotri 1977) and further experiments are required to assess whether grazing rates are affected by nutrient supply to the macroalgae (as is common in algal and seagrass beds worldwide; Hughes et al. 2004).”
The emerging role of genetic diversity for ecosystem functioning: Estuarine macrophytes as models (2006, background): “Epiphytic algae can have strong effects on seagrasses (Hughes et al. 2004) and other macrophytes, yet it is unknown how the species or genetic diversity of epiphytes interacts with the genetic diversity of the host species.”
Marine megaherbivore grazing may increase seagrass tolerance to high nutrient loads (2012, background): “Although other studies have addressed the interactive effects of nutrient availability and herbivory on marine primary producers (reviewed in Hughes et al. 2004; Tewfik, Rasmussen & McCann 2005; Burkepile & Hay 2006; Heck&Valentine 2007), these did not involvemegaherbivores.”
Shift in fish assemblage structure due to loss of seagrass Zostera marina habitats in Sweden (2006, unknown): “Turbidity and surplus algal growth may derive from physical disturbances on land or in the water, and from eutrophication combined with trophic cascades (e.g. effects of over-fishing) in the coastal ecosystem (Howarth et al., 2000; Jackson et al., 2001; Hughes et al., 2004).”
The ecological role of Holothuria scabra (Echinodermata: Holothuroidea) within subtropical seagrass beds (2009, background): “A recent meta-analysis found that sediment nutrients are the key limiting factors to seagrass growth and biomass rather than light (Hughes et al., 2004).”
The ecological role of bivalve shellfish aquaculture in the estuarine environment: A review with application to oyster and clam culture in West Coast (USA) estuaries (2009, background): “In general an increase in sediment porewater ammonium toward optimal levels (~100 μM) should enhance plant biomass and growth (Dennison et al., 1987; Hughes et al., 2004), although high levels of biodeposits could lead to toxic sulfide concentrations especially in already eutrophic areas (Sorokin…”
