Seaweeds provide food and shelter for countless species of invertebrates. Many studies show how particular species of seaweed facilitate particular invertebrates, but few examine the simultaneous effects of multiple seaweeds, despite the fact that algal composition and diversity are known to vary considerably. We conducted laboratory experiments to determine how algal species richness affected the consumption and growth of 2 common rocky shore herbivores: the turban snail Chlorostoma funebralis… 

Figures and Tables from this paper

Plant-animal diversity relationships in a rocky intertidal system depend on invertebrate body size and algal cover.

It is found that diverse algal communities hosted more species of both large and small invertebrates than the average algal monoculture but that the mechanisms underlying this pattern differed substantially for organisms of different size.

What and when to eat? Investigating the feeding habits of an intertidal herbivorous starfish

Investigation of the feeding habits of the intertidal herbivorous starfish Parvulastra exigua showed that this starfish forages on a narrow range of algal food resources, with an apparent selection for microalgae.

What and when to eat? Investigating the feeding habits of an intertidal herbivorous starfish

Although the ecology of molluscan grazers on intertidal rocky shores is very well documented, there are other abundant grazers, such as herbivorous starfish, that can modify the structure of benthic

Diet of the Wavy Turban Snail, Megastraea undosa (Gastropoda: Turbinidae), in Subtropical Rocky Reefs 1

The wavy turban snail, Megastraea undosa (W. Wood), is an important fishery resource along the Mexican Pacific coast and a keystone species in subtropical rocky reefs, which was reflected in its variable trophic niche width.

Assessing Feeding Preferences of a Consumer Guild: Partitioning Variation Among versus Within Species

Examining feeding preference through repeated laboratory choice feeding assays of 444 wild-caught individuals of eight invertebrate grazer species on rocky reefs in northern California finds diet variation between and within individuals can contribute to the dietary niche width of species and guilds, which may be overlooked by focusing solely on species’ mean resource use patterns.

Trait-mediated indirect interactions among residents of rocky shore tidepools

It is demonstrated that TMIIs could occur in natural tidepools and showed how predator and algal identity, predator and prey size, water flow and prey hunger level may influence these TMII.

Nutrition of marine mesograzers: integrating feeding behavior, nutrient intake and performance of an herbivorous amphipod

It is concluded that an integrative approach that considers the intake of multiple nutrients potentially yields insights into feeding behavior and its performance consequences and carbon and nitrogen seem to emerge as the nutrient components that are more strongly regulated by A. valida.

Resource-dependent foraging behaviour of grazers enhances effects of nutrient enrichment on algal biomass.

Both the quantity and nutritional quality of food resources can strongly influence the foraging movements of herbivores, which in turn determine the strength of top-down control on primary producer

Shifts in seawater chemistry disrupt trophic links within a simple shoreline food web

Results demonstrate direct negative effects of low pH on anti-predator behavior of snails, but also weakened indirect interactions, driven by increased snail consumption of macroalgae even as sea stars ate more snails.



Plant Species Diversity in a Marine Intertidal Community: Importance of Herbivore Food Preference and Algal Competitive Abilities

Predators or herbivores do not simply increase or decrease species diversity of their food, but can potentially do both and the results may apply to most generalized consumers and provide a framework within which previously confusing results can be understood.

Seaweed richness and herbivory increase rate of community recovery from disturbance.

Herbivory and species richness should jointly accelerate recovery wherever palatable species inhibit late-successional, herbivore-resistant species and recruitment and survival of new colonists is promoted by local species richness.

Diet composition influences the fitness of the herbivorous crab Grapsus albolineatus

The fitness of G. albolineatus appears to be limited by the amount of extra nutrients obtained from animal matter, which could be a key factor in the reproductive success of this crab.

The effects of diet mixing on consumer fitness: macroalgae, epiphytes, and animal matter as food for marine amphipods

Diet mixing may benefit more mobile consumers like Gammarus that are better able to search for different foods, and may be less important for more sedentary herbivores like Ampithoe and Cymadusa that consume, and live in close association with, individual host plants.

Selectivity and Growth of the Generalist Herbivore Dolabella Auricularia Feeding Upon Complementary Resources

The results suggest that Dolabella actively maintains a mixed diet because it is nutritionally superior to any single diet, and consumer foraging will tend to destabilize the resource community, because rarer resources will be disproportionately consumed.

Food preference, food quality and diets of three herbivorous gastropods (Trochidae: Tegula) in a temperate kelp forest habitat

Despite their strong preference for Macrocystis, the 3 species of herbivorous kelp forest gastropods (Tegula) had significantly greater growth and/or reproductive development on a mixed-algae diet than on either brown or red algae alone.

Nutritional quality of macrophytes eaten and not eaten by two temperatezone herbivorous fishes: A multivariate comparison

The mean annual chemical compositions of 23 species of macrophytes from a rocky intertidal habitat on the central California coast were determined to test the hypothesis that the 13 red and green seaweeds eaten by the two principal herbivorous fishes at the site are higher in nutritional quality than the 9 red and brown seaweeds and the seagrass not consumed by these fishes.

Differences in herbivore feeding preferences across a vertical rocky intertidal gradient

The results suggest that the intensity of herbivory may change with tidal elevation in more complex ways than previously suspected, and that studies of macroalgal palatability and anti- herbivore defenses in these systems will need to examine the relative impacts of a range of herbi- vores on algal community structure.

Dietary mixing in three generalist herbivores: nutrient complementation or toxin dilution?

It is argued that there is no easy way to distinguish between the two hypotheses on the basis of consumption and performance measurements, as has previously been proposed, and where in the sequence from ingestion to growth single diets caused differences from mixed diets.
