Dietary analysis of the marine Amphipoda (Crustacea: Peracarida) from the Iberian Peninsula (2014, background): “Duffy and Hay (2000), based on mesocosm experiments, reported that grazing amphipods, which are ubiquitous in marine vegetation but poorly understood ecologically, may have strong impacts and play important roles in the organization of benthic communities, particularly where predation pressure is…”
Seaweed-herbivore interactions at a small scale: direct tests of feeding deterrence by filamentous algae (2006, background): “Unlike large herbivores that can remove a filamentous individual in a single bite, small herbivores make feeding choices at a fine scale and can be present at high densities (Brawley & Adey 1981, Duffy & Hay 2000).”
Cascading effects of predator diversity and omnivory in a marine food web (2005, background): “Amphipod and isopod herbivores prefer brown and filamentous green algae such as Enteromorpha and in general do not consume Hypnea and Codium ( Duffy & Hay 2000 ) (Table S5), which dominated the no predator treatment (Fig. 3b).”
Habitat choice and predator avoidance by Antarctic amphipods: the roles of algal chemistry and morphology (2010, background): “Amphipods can be as important as herbivorous fishes in structuring benthic communities (Brawley & Adey 1981, Duffy & Hay 2000) and are likely to be responsible, via herbivory, for the near-total lack of filamentous macroalgal epiphytes in the Antarctic subtidal ecosystem (Amsler et al. 2009a).”
Species-specific impacts of grazing amphipods in an eelgrass-bed community (2001, background): “…permitted without written consent of the publisher Mar Ecol Prog Ser 223: 201–211, 2001 1974, Klumpp et al. 1989, Edgar & Shaw 1995, Taylor 1998), and in structuring the assemblages of plants on which they feed (Orth & van Montfrans 1984, Jernakoff et al. 1996, Duffy & Hay 2000, Duffy et al. 2001).”
NUTRIENT ENHANCEMENT INCREASES PERFORMANCE OF A MARINE HERBIVORE VIA QUALITY OF ITS FOOD ALGA (2002, background): “Recent studies on the regulation of marine algal assemblages have found that mesograzers may strongly modify the benthic community structure by selective grazing and by suppressing macroalgal blooms (Duffy and Hay 2000, Lotze et al. 2000, Worm et al. 2000).”
Natural densities of mesograzers fail to limit growth of macroalgae or their epiphytes in a temperate algal bed (2009, background): “…conducted over a longer duration, although previous mesocosm experiments have detected effects on algal assemblages within 1 (Duffy 1990), 2 (Ruesink 2000), 3 (Bruno & O’Connor 2005; O’Connor & Bruno 2007) or 4 weeks (Duffy & Hay 2000) – all periods much shorter than our 10-week experiment.”
Relative effects of grazers and nutrients on seagrasses: a meta-analysis approach (2004, background): “…differences in the diets of small invertebrate grazers can underlie significant variation in epiphyte biomass and community composition, and have important implications for seagrass communities (Zimmerman et al. 1979, Kitting 1984, Duffy & Hay 2000, Duffy & Harvilicz 2001, Duffy et al. 2001).”
Species richness in macroalgae and macrofauna assemblages on Fucus serratus L. (Phaeophyceae) and Zostera marina L. (Angiospermae) in Skagerrak, Norway (2005, background): “…mobile grazers (and also higher trophic levels) and these interactions have been found to be of importance for primary and secondary production, diversity, and the persistence (stability) of these systems (Jernakoff et al. 1996; Duffy & Hay 2000; Duffy & Harvilicz 2001; Duffy et al. 2001, 2003).”
GRAZER DIVERSITY, FUNCTIONAL REDUNDANCY, AND PRODUCTIVITY IN SEAGRASS BEDS: AN EXPERIMENTAL TEST (2001, background): “Using mesocosm experiments in a seaweed-dominated hard-substratum community, Duffy and Hay (2000) found that algal abundance and community structure differed markedly between treatments with and without amphipods, despite similar abundances of gastropods, isopods, and total mesograzers.”
Ultraviolet radiation shapes seaweed communities (2006, background): “Alga-herbivore interactions The consumption of plant biomass represents the most fundamental plant-animal interaction, affecting biomass accrual and community composition of photoautotrophs (Sousa and Connell 1992; Duffy and Hay 2000).”
Density-dependent sea urchin grazing: differential removal of species, changes in community composition and alternative community states (2005, background): “Although temperate brown algae off North Carolina that are unpalatable to grazing fish are dominant where these fish are common (Miller & Hay 1996, Duffy & Hay 2000), this is the first description of a community-structuring role for differential grazing by temperate sea urchins linked to algal…”
