Because food and habitat are closely linked for small herbivores that live on plants, food choice in the field may be constrained by the need to choose plants that provide safe living sites. We investigated the importance of food value and refuge value in determining the plant utilization patterns of the herbivorous marine amphipod Ampithoe longimana. When offered a choice of five common seaweeds, this amphipod fed most readily on Dictyota and Hypnea and less readily on Sargassum, Chondria, and… Expand

Habitat and food selection by herbivorous amphipods associated with macroalgal beds on the southeast coast of Brazil
TLDR
The different results for C. filosa suggest that the pattern of feeding and habitat selection can be affected by external characteristics of the algae, and probably, refuge from predation is an important selective force acting on the use of algae by these animals. Expand
Predation constrains host choice for a marine mesograzer
TLDR
It is suggested that seaweed refuge quality, not nutritional quality, drives A. typica host preference and distribution in this system. Expand
Restricted host use by the herbivorous amphipod Peramphithoe tea is motivated by food quality and abiotic refuge
TLDR
Egregia’s value as good quality food and refuge from abiotic stress together explain the restricted host use of P. tea, suggesting the possibility that the host preferences of local populations may respond evolutionarily to geographic shifts in seaweed communities. Expand
Testing the importance of predation refuge vs. food quality in determining the use of macroalgal hosts by a generalist marine mesograzer
TLDR
The distribution of Cymadusa was explained by a balance between food and refuge values of hosts, with higher abundances being observed in the high-quality food alga that provides refuge against predators (e.g. Padina), while fewer individuals occurred in other high- quality food that was less suitable as refuge (eg. Sargassum). Expand
Feeding preferences and performance of an aquatic lepidopteran on macrophytes: plant hosts as food and habitat
TLDR
The results suggest that relative growth rates, chemical cues, and previous feeding experience are important factors determining feeding preference in the semi-aquatic lepidopteran Munroessa gyralis and that host use may be restricted due to life-stage-specific developmental constraints that are not apparent from the results of growth or preference assays. Expand
Host-plant specialization by a non-herbivorous amphipod: advantages for the amphipod and costs for the seaweed
TLDR
It is demonstrated that habitat specialists can negatively impact hosts without consuming them and that specialization on a plant can occur due to its habitat value alone (as opposed to its value as a food). Expand
Feeding preferences of the sandhopper Orchestoidea tuberculata: the importance of algal traits
TLDR
The results imply that the composition of the macroalgae arriving on the beach can significantly affect the performance and subsequent life history traits of O. tuberculata and by extension other amphipod species. Expand
Comparing macroalgal food and habitat choice in sympatric, tube-building amphipods, Ampithoe lacertosa and Peramphithoe humeralis
TLDR
Feeding and habitat preferences of the two species were not clearly linked to nitrogen content of the algae, C:N ratio, or toughness of the algal tissue, and results suggest that the nutritional requirements of these sympatric mesograzers differ considerably and even closely related species can exhibit divergent behavioral strategies. Expand
Strong consequences of diet choice in a talitrid amphipod consuming seagrass and algal wrack
TLDR
It is suggested that feeding by Notorchestia will result in the rapid loss of Sargassum in the wrack, and that other consumers or microbial degradation may be more important in the decomposition of seagrass. Expand
Feeding preferences and performance of a marine isopod on seaweed hosts: cost of habitat specialization
TLDR
It is shown that feeding preferences and habitat choice behavior evolve together; habitat structure, in terms of predation avoidance, and the spatiotemporal stability of the host algae are more important factors selecting for feeding preferences in mesoherbivores than the chemical composition of algae.

Food choice, feeding rates, and the turnover of macrophyte biomass by a surf-zone inhabiting amphipod
TLDR
Estimates of the significance of the Allorchestes compressa population in the turnover of Ecklonia radiata biomass in the surf-zone showed that amphipods could turnover E. radiATA biomass twice per month in summer and once every 1 to 2 months during spring and autumn. Expand
Chemical Defense Against Different Marine Herbivores: Are Amphipods Insect Equivalents?
TLDR
The ability of amphipods to circumvent the chemical defenses of Dictyota, and the fact that the two species of algae most readily consumed by amphipODs were the twospecies least readily consumedBy fish, suggest that predation and herbivory by fishes may be major factors selecting for amphipod that can live on, and eat, seaweeds that are unpalatable to fishes.

Feeding capabilities and limitation of herbivorous molluscs: A functional group approach
TLDR
Algae are subdivided into seven functional groups based on the size and toughness of the plant relative to the feeding ability of the mollusc, and this functional group approach suggests various hypotheses concerning algal community structure, plant/herbivore and herbivore/herBivore interactions, the relative importance of structural defenses in algae, and the evolution of specialized grazers.

Chemical defense in the seaweed Dictyopteris delicatula: differential effects against reef fishes and amphipods
TLDR
It is hypothesized that mesograzers living on plants chemically defended from fishes will experience less predation than those living on Plants preferred by fishes. Expand
HABITAT ARCHITECTURE AND THE ABUNDANCE AND BODY-SIZE-DEPENDENT HABITAT SELECTION OF A PHYTAL AMPHIPOD'
TLDR
It appears, through the use of algal mimics, that the spatial component (space between fronds) is an important factor in determining amphipod demographic patterns in algae. Expand
Does algal morphology affect amphipod susceptibility to fish predation
TLDR
This study evaluated the hypothesis that phytal amphipods are less susceptible to predation by fishes when on highly branched, morphologically complex algal hosts than when on seaweeds with a simple bladed morphology and found that this conclusion is correct. Expand
Host‐Plant Specialization Decreases Predation on a Marine Amphipod: An Herbivore in Plant's Clothing
TLDR
The hypothesis that predator escape and deterrence are primary factors selecting for host specialization by Pseudamphithoides incurvaria is consistent and conclusions can be drawn for the limited number of other marine herbivores that are relatively specialized. Expand
Marine Plant-Herbivore Interactions: The Ecology of Chemical Defense
TLDR
Although numerous seaweed characteristics can deter some herbivores, the effects of morphology and chemistry have been studied most thoroughly and these types of seaweeds may be considered herbivore tolerant. Expand
Factors involved in herbivore food preference
TLDR
In conclusion, Idotea's mobility, possible susceptibility to fish predation, and preference for moderate wave exposures may select for a primary response to algae as habitat rather than as food source. Expand
Refuges from Fish Predation: Experiments with Phytal Meiofauna from the New Zealand Rocky Intertidal
TLDR
The results and those from the literature suggest that fish predation on benthic invertebrates may not be linearly related to decreasing substrate complexity, and there appears to be a complexity threshold below which removal rate is not significantly affected by structure and above which removal rates are significantly reduced.
