Biodiversity and the functioning of seagrass ecosystems (2006, background): “…seagrass beds specifically, epiphyte grazers have impacts on seagrasses that are comparable in magnitude, but opposite in sign, to those of the water-column nutrient loading widely recognized as a major threat to seagrass systems (Williams & Ruckelshaus 1993, Heck et al. 2000, Hughes et al. 2004).”
Extinction risk assessment of the world’s seagrass species (2011, background): “Mechanical damage from boats, boat moorings, and docks is a problem in some regions (Burdick and Short, 1999; Kenworthy et al., 2002), as are introduced species (Williams, 2007) that compete for space and resources (Heck et al., 2000).”
Marine megaherbivore grazing may increase seagrass tolerance to high nutrient loads (2012, background): “…of seagrass overgrowth by selective epiphyte grazing, as found for mesoherbivores (Short, Burdick &Kaldy 1995; Gacia, Littler & Littler 1999; Heck et al. 2000; Boyer et al. 2004; Hays 2005), is of minor importance at our study site, as megaherbivores cannot selectively remove epiphytes from…”
NUTRIENT ENHANCEMENT INCREASES PERFORMANCE OF A MARINE HERBIVORE VIA QUALITY OF ITS FOOD ALGA (2002, background): “There exists some evidence that mesograzer densities may be limited by food quantity (Edgar and Aoki 1993), but, on the other hand, several studies (e.g., Van Dolah 1978, Heck et al. 2000) have reported considerable topdown effects of fishes in reducing the numbers of mesograzers.”
Trophic interactions in Zostera marina beds along the Swedish coast (2008, background): “…WORDS: Seagrass · Eelgrass · Zostera · Stable isotopes · Mixing model · Trophic interactions Resale or republication not permitted without written consent of the publisher Mar Ecol Prog Ser 369: 63–76, 2008 rise in epiphyte biomass (Heck et al. 2000, Valentine & Heck 2001).”
Effect of habitat complexity on predation success: re-evaluating the current paradigm in seagrass beds (2009, methodology): “The number of predators and prey used in each seagrass density treatment were designed to closely mimic their natural abundance by consulting previously recorded observations in the Gulf of Mexico (Coen et al. 1981, Gore et al. 1981, Huh 1984, Heck et al. 2000, Spitzer et al. 2000).”
Eutrophication in shallow coastal bays and lagoons: the role of plants in the coastal filter (2007, background): “…sponges, polychaetes, amphipods, gastropods, and small herbivorous fish to buffer the effects of nutrient enrichment (e.g. Alpine & Cloern 1992, Neckles et al. 1993, Williams & Ruckelshaus 1993, Lin et al. 1996, Heck et al. 2000, Hillebrand et al. 2000, Lotze & Worm 2002, Heck & Valentine 2007).”
RELATIVE ROLES OF HERBIVORY AND NUTRIENTS IN THE RECRUITMENT OF CORAL-REEF SEAWEEDS (2003, unknown): “…increases in algal populations than does nutrient enrichment, including studies of mature benthic algae on coral reefs (Miller et al. 1999, Thacker et al. 2001, Jompa and McCook 2002), in seagrass beds (Heck et al. 2000), and in freshwater periphyton communities (Hillebrand and Kahlert 2001).”
Shift in seagrass food web structure over decades is linked to overfishing (2012, background): “…and reduce the abundance of their main food items within the mesograzer group (e.g. small herbivorous amphipods, gastropods and har - pacticoids), causing an easing of grazing pressure and a subsequent increase in nuisance algae (e.g. Heck et al. 2000, Jackson et al. 2001, Burkepile & Hay 2006).”
Opposing organizing forces of deposit-feeding marine communities (2004, background): “…reefs (Ogden et al., 1973; Sammarco, 1982), sea otters in kelp beds (Duggins, 1980; Estes and Palmisano, 1974; Harrold and Reed, 1985), lobsters and urchins in shallow subtidal and low intertidal habitats (Robles et al., 1990; Vadas and Steneck, 1995), and fish in seagrass beds (Heck et al., 2001).”
Relative effects of grazers and nutrients on seagrasses: a meta-analysis approach (2004, background): “Small fishes (e.g. pinfish, Lagodon rhomboides) in seagrass systems consume both epiphytes and invertebrates during different parts of their life cycle (Heck et al. 2000), complicating predictions of the consequences of decreased predation pressure from large fish.”
Effects of herbivores on a Posidonia oceanica seagrass meadow: importance of epiphytes (2005, background): “Moreover, the beneficial effect of grazers on seagrasses, by reducing competition with epiphytes for primary resources and enhancing plant production, also needs to be considered (Orth & van Montfrans 1984, Brönmark 1985, Neckles et al. 1993, Williams & Ruckelshaus 1993, Heck et al. 2000).”
Experimental nutrient enrichment causes complex changes in seagrass, microalgae, and macroalgae community structure in Florida Bay (2005, background): “Grazing can structure temperate and tropical seagrass communities through direct consumption of seagrass (McGlathery 1995; Valentine and Heck 2001), controlling epiphyte growth (Williams and Ruckelshaus 1993; Heck et al. 2000), and regulating benthic microalgal production (Nilsson et al. 1991).”
