The palatable plants investigated in this study gained significant protection from herbivores by associating with abundant competitors that were less susceptible to herbivory. When herbivores were excluded, palatable species associated with unpalatable ones grew at only 14%-19% of the rate of palatable plants separated from unpalatable ones. When herbivores were present, however, palatable species appeared to depend completely on unpalatable competitors to provide microsites of reduced… Expand
Associational resistance and shared doom: effects of epibiosis on herbivory
TLDR
This study evaluated how different associations between host seaweeds and epibiotic plants and animals influenced the movement of an omnivorous sea urchin to the host and subsequent feeding on the host, finding that unpalatable hosts fouled by palatable epibionts became much more attractive to urchins and rose several ranks on the urch Ins' preference hierarchy.

A neighboring plant species creates associational refuge for consumer and host.
TLDR
In salt marshes in the Gulf of Mexico, the marsh periwinkle (Littoraria irrorata) is an abundant and conspicuous member of the community, climbing up the stems of marsh plants to remain out of the water at high tide. Expand
Community Complexity Drives Patterns of Natural Selection on a Chemical Defense of Brassica nigra
TLDR
The results show that the selective value of ecologically important traits depends on the complicated web of interactions present in diverse natural communities and that fluctuations in community composition may maintain genetic variation in such traits. Expand
Crab herbivory regulates plant facilitative and competitive processes in Argentinean marshes.
TLDR
Results show that herbivory can mediate the balance between facilitative and competitive processes in vascular plant communities and that the strength of consumer regulation of interactions can vary seasonally and with patch size. Expand
HABITAT MODIFICATION AND REFUGE FROM SUBLETHAL STRESS DRIVE A MARINE PLANT–HERBIVORE ASSOCIATION
Canopy-forming plants and algae, in addition to their role as food, can positively affect higher trophic levels by providing protection from predation or stressful abiotic conditions. In the lowExpand
Trophic Consequences of a Positive Plant Interaction
TLDR
It is shown that, without plant neighbors, aphid colonization increases on host plants but that negative population growth rates ensure local extinction at all levels of the food chain. Expand
Food Selection by Herbivores and Neighbourhood Effects in the Evolution of Plant Defences
TLDR
This work outlines two basic situations of non-parallel neighbourhood effects and illustrates how they can come about, and reveals that there are several qualitatively distinct mechanisms that promote either evolutionary stability of plant defences or alternatively polymorphism. Expand
Positive and negative effects of a dominant competitor on the settlement, growth, and survival of competing species in an epibenthic community
TLDR
The total effect of Ascidia on the community will depend on species-specific and life stage-specific effects, with likely long-term consequences for the diversity and composition of the community. Expand
Good neighbors make good defenses: associational refuges reduce defense investment in African savanna plants.
TLDR
It is shown experimentally that associational refuges and induced resistance interact to create predictable intraspecific variation in defense phenotype in African savanna plants and that inducible responses enable plants to capitalize on such associations in heterogeneous environments. Expand
Associational resistance protects mangrove leaves from crab herbivory
TLDR
The combined results argue for the need for additional experiments to elucidate mechanisms responsible for defensive plant associations in mangrove ecosystems and to determine whether such associations could be of use inMangrove restoration. Expand

Organization of a Plant-Arthropod Association in Simple and Diverse Habitats: The Fauna of Collards (Brassica Oleracea)
TLDR
The results suggest a new proposition, the resource concentration hypothesis, which states that herbivores are more likely to find and remain on hosts that are growing in dense or nearly pure stands; that the most specialized species frequently attain higher relative densities in simple environments; and that biomass tends to become concentrated in a few species, causing a decrease in the diversity of herbsivores in pure stands.

Plant Defense Guilds
TLDR
A framework of operational mechanisms that begin to clarify some aspects of the recognized influence of species diversity on herbivory are discussed, including diversionary and delaying tactics to the adaptation-counteradaptation view of plant-herbivore coevolution. Expand
Plant Species Diversity in a Marine Intertidal Community: Importance of Herbivore Food Preference and Algal Competitive Abilities
TLDR
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. Expand
An "Indirect Commensalism" between Marine Herbivores and the Importance of Competitive Hierarchies
TLDR
It is shown that the type of competition between prey (i.e., hierarchical vs. symmetrical) strongly affects the nature of the interaction between consumers, and that in systems in which resource taxa compete, the abundance of a consumer specialized on one prey should be positively affected by the presence of a specialized consumer of the other prey.

INSECT HERBIVORE ABUNDANCE IN TROPICAL MONOCULTURES AND POLYCULTURES: AN EXPERIMENTAL TEST OF TWO HYPOTHESES'
TLDR
The study of population dynamics of six beetle pests in monocultures and polycultures of the corn-bean-squash agroecosystem in Costa Rica suggests that the Resource Concentration Hypothesis rather than the Enemieshypothesis can account for differences in beetle abundance. Expand
THE POPULATION DYNAMICS OF SEVERAL HERBIVOROUS BEETLES IN A TROPICAL AGROECOSYSTEM: THE EFFECT OF INTERCROPPING CORN, BEANS AND SQUASH IN COSTA RICA
TLDR
Considering the mechanisms and time at which the beetles typically cause economic damage to the crops, it is possible that decreased beetle abundance contributed to greater yields of the intercrops and the traditional practice of intercropping may therefore be a cultural method of pest control.

Effects of grazing by Diadema antillarum Philippi (Echinodermata: Echinoidea) on algal diversity and community structure
TLDR
Species composition of algae in the benthic community prior to changes in grazing pressure and lack of successful recruitment of a potential dominant were found to have a major influence on the response of the algal community to the treatments. Expand

It is suggested that herbivorous fish grazing profoundly influences benthic species distributions and abundances within some tropical reef habitats and spatial variation in herbivory appears to be of fundamental importance in determining regional patterns of benthics community structure on tropical reefs.
