The susceptibility of an alga to an herbivorous mollusc depends, in part, upon the size and toughness of the plant relative to the feeding ability of the mollusc. In this study, algae are subdivided into seven functional groups based on these and other physiological characteristics. Herbivorous prosobranchs and chitons are subdivided into four functional groups based on the structure of their feeding apparatus. Distinct patterns in the diets of these molluscs are evident when feeding data… Expand

Herbivory and Between‐Habitat Diversity: The Differential Effectiveness of Defenses in a Marine Plant
TLDR
Interactions among the intertidal alga Iridaea cordata and five common herbivores of the Oregon coast emphasize that the variety of consumers can be as important as the magnitude of feeding. Expand
Algal resistance to herbivory on a Caribbean barrier reef
TLDR
Field and laboratory research at Carrie Bow Cay, Belize showed that macroalgae, grouped in functional-form units resisted fish and urchin herbivory in the following order, supporting the hypothesis that crustose, calcareous and thick algae have evolved antipredator defenses and should show the greatest resistance to Herbivory with a gradation of increasing palatability towards filaments and sheets. Expand
Structural resistance of algae to herbivores
TLDR
Thallus form alone is a poor predictor of structural resistance to molluscan feeding; the material properties of the alga, the feeding apparatus of the herbivore, and the mode of feeding all must be considered. Expand
Grazing effect of two Gibbula species (Mollusca, Archaeogastropoda) on the epiphytic community of Posidonia oceanica leaves
TLDR
The temporal and spatial patterns of the molluscs Gibbula ardens and G. umbilicaris, which inhabit beds of Posidonia oceanica, indicated that these species occupy well-differentiated niches. Expand
Susceptibility of macroalgae to herbivorous fishes at Rocas Atoll, Brazil
TLDR
This differential susceptibility of the seaweeds to herbivory associated with different spatial Herbivory pressure may be responsible for the variable distribution and abundance of seaweeds around the Rocas Atoll reef. Expand
Chemical mediation of seaweed-herbivore interactions
Seaweeds produce a variety of secondary metabolites that deter feeding by herbivores. T h e defensive value of a compound is, however, a specific function of the compound's structure and the speciesExpand
Induced resistance in intertidal macroalgae modifies feeding behaviour of herbivorous snails
TLDR
This study is the first to demonstrate that herbivory-induced changes in the tissue chemistry of the brown seaweed Ascophyllum nodosum elicit the same response in the feeding behaviour of the gastropod Littorina obtusata as predicted for herbivorous insects, providing good evidence for the model’s validity across different ecosystems.

Algal Structure Defenses: Form and Calcification in Resistance to Tropical Limpets
Growth form and calcification in marine macrophytes have been suggested to act as structural defenses against grazers. Support for this hypothesis has been largely indirect, consisting of negativeExpand
The functional roles of herbivores in the rocky intertidal systems in Chile : A review of food preferences and consumptive effects
This paper reviews recent knowledge about the functional roles that herbivores have in intertidal communities in Chile. Specifically, I review field and laboratory studies dealing with the foodExpand
Feeding Ecology and Radular Morphology of the Freshwater Limpet Ferrissia fragilis
TLDR
This study provides evidence for resource partitioning of different growth forms of epiphytic algae by gastropod species that occupy the same submerged macrophytes and may imply that vacant niches, containing adnate algal species, are present in those freshwater habitats that lack grazers like Ferrissia.

Grazing Effects of Four Marine Intertidal Herbivores on the Microflora
TLDR
Differences in grazer zonation and use of macroalgae, coupled with increased food availability during reproductive seasons (winter and spring), allow continued coexistence of these very similar herbivores. Expand
A Limpet‐Coralline Alga Association: Adaptations and Defenses Between a Selective Herbivore and its Prey
TLDR
The number of apparently specific adaptations of both organisms, with mutual advantages, suggests evolution toward a coevolved interdependency. Expand
Feeding adaptations of Melagraphia aethiops (Gmelin), an intertidal trochid mollusc
TLDR
The feeding behaviour of the intertidal trochid Melagraphia aethiops (Gmelin) on a sheltered stony shore was investigated and high and low shore inhabiting snails showed little difference in radula rasping rates. Expand
Differential susceptibility to grazers in two phases of an intertidal alga: Advantages of heteromorphic generations
TLDR
“Bet-hedging” is suggested in explanation of the maintenance of two phases in one cycle; the crust is more persistent but susceptible to overgrowth, while the more productive blade is more susceptible to grazing. Expand
Heteromorphic Life Histories of Certain Marine Algae as Adaptations to Variations in Herbivory
TLDR
Experimental removal of herbivores on the coasts of New England and Oregon resulted in the occurrence of the upright morphs in the times of year when they were normally absent, demonstrating that such uprights can survive the summertime physical regime (contrary to earlier speculation). Expand
Herbivore‐Plant Interactions of Individual Limpets Maintaining a Mixed Diet of Intertidal Marine Algae
TLDR
A family of simple graphic models illustrates hypothetical tendencies to select a particular (proportioned) mixture of foods, and predicts how food preferences would differ where relative abundances of the foods differ. Expand
THE EFFECTS OF GRAZING BY SEA URCHINS, STRONGYLOCENTROTUS SPP., ON BENTHIC ALGAL POPULATIONS1
TLDR
Observations of the rate and pattern of algal succession for periods of up to three years showed that following an initial establishment of new species, brown algae began to dominate and the rate of domination is related to the area’s tidal height, with succession most rapid in the lower intertidal areas or subtidally.

The Evolution of Thallus Form and Survival Strategies in Benthic Marine Macroalgae: Field and Laboratory Tests of a Functional Form Model
TLDR
Data on succession, productivity, and toughness indicate that E. menziesii shifts from an opportunistic strategy during its juvenile stages to a highly differentiated complex form able to persist in mature successional stages, thus implicating selection for persistence as opposed to rapid growth in climax communities.

Morphological Form and Photosynthetic Performances of Marine Macroalgae: Tests of a Functional / Form Hypothesis
TLDR
The hypothesis that morphology and photosynthetic performance are related and the adaptive significance of thallus form as it pertains to the productivity ecology of rocky intertidal seaweeds is tested is tested. Expand
Experimental Evaluation of Ecological Dominance in a Rocky Intertidal Algal Community
TLDR
Algal succession in deeper Portage Head tidepools was found to be relatively slow with no clear dominance expressed after 5 yr, and the rate of algal succession following removal of the dominant algal species or of Strongylocentrotus is proportional to the degree of wave exposure. Expand
