Generalisations on the combined effects of consumers and resources on autotrophs in aquatic food webs largely rely on freshwater studies. In this study, we tested these general concepts with marine benthic microalgae, which are important components of coastal food webs. We manipu- lated nitrogen availability and herbivore presence in a factorial field experiment in the Western Baltic Sea. Moreover, we investigated how herbivore control varied among 3 sites and 2 seasons and tested for trophic…

There was no complete propagation of bottom-up effects through the community, and strong internal feedback mechanisms within the periphyton mediated the effects of macroconsumers and nutrient enrichment.

Herbivore-mediated increase in the photosynthetic capacity of marine biofilms: indirect effects of changing microalgal assemblage composition

The results indicate that the phys- ical disturbance caused by littorinid grazing changes the composition of microalgal assemblages to one dominated by more productive taxa.

Endemic grazers control benthic microalgal growth in a eutrophic tropical brackish ecosystem

The results suggest that grazing is the primary driver of epilithon composition and biomass across these nutrient-enriched systems, microphytobenthic communities in these systems are not N or P limited irrespective of co-varying salinity and background nutrients and selective feeding by endemic grazers mitigates potential bottom-up forces from salinity or increased nutrient- enriched groundwater influence on autotrophy in epilithson communities.

Effects of nutrients, herbivory, and depth on the macroalgal community in the rocky sublittoral.

It is concluded that grazers are able to reduce macroalgae over a large range of nutrient availabilities, up to 12-fold nutrient enrichment in the current experiment, and that the sublittoral depth gradient generates variation in the algal community control exerted by both herbivory and nutrient availability.

A novel interaction between nutrients and grazers alters relative dominance of marine habitats

A novel interaction between nutrients (bottom-up control) and grazing pressure (top-down control) is demonstrated, which are funda- mental to predictions about management of human activities that continue to reduce densities of herbivores and increase nutrient availability on temperate coasts.

Response of microphytobenthic biomass to experimental nutrient enrichment and grazer exclusion at different land-derived nitrogen loads

Effects of eutrophication on the relative importance of nutrients and macroherbivores as controls of microphytobenthic standing crop were examined in estuaries with different nitrogen load- ing

Nutrient and herbivore alterations cause uncoupled changes in producer diversity, biomass and ecosystem function, but not in overall multifunctionality

It is revealed that anthropogenic pressures can induce decoupled effects between community structure and specific ecosystem functions, and the need to address several ecosystem functions simultaneously for better ecosystem characterization and management is highlighted.

Gastropod grazers and nutrients, but not light, interact in determining periphytic algal diversity

This study shows that nutrient addition substantially reduced the negative effects of grazing on periphytic algal diversity, whereas light did not interact with grazing or nutrient enrichment in determining peripHYticAlgal diversity.

Diverse Dietary Responses by Saltmarsh Consumers to Chronic Nutrient Enrichment

The abundance and frequency of occurrence of O. grillus on creek-wall habitats increased with chronic nutrient enrichment suggesting amphipods contribute to top–down control on benthic algae and slow algal growth as nutrient enrichment occurs.

Effect of grazing and nutrient supply on periphyton biomass and nutrient stoichiometry in habitats of different productivity

The impact of grazing and nutrient supply on epilithic periphyton was investigated in factorial field experiments in four seasons at three Swedish sites of different productivity and herbivore



Coastal food web structure, carbon storage, and nitrogen retention regulated by consumer pressure and nutrient loading

The results emphasize the important role of grazers in buffering moderate eutrophication effects and illustrate how food web interactions and shifts in species composition are tightly linked to coastal ecosystem function.

Interactive Effects of Nutrient Reduction and Herbivory on Biomass, Taxonomic Structure, and P Uptake in Lotic Periphyton Communities

Periphyton biomass was significantly greater in streams without snails than in those with them, but water supply had no overall significant effect on biomass, even though inorganic P and N concentrations were significantly lower in recirculated than in once-through streams.


Fish can augment this effect by negatively affecting snail life history traits and by reducing grazing activity by changing nutrient concentrations and possibly altering competitive outcomes among taxa and growth forms.

Top‐Down and Bottom‐Up Control of Stream Periphyton: Effects of Nutrients and Herbivores

Nutrient addition positively affected snail growth in both experiments, indicating tight coupling between herbivore and algal growth (top-down ef? fects) and that bottom-up factors that directly affected plant growth could also indirectly affect consumers belonging to higher trophic levels.

The impact of herbivore type and grazing pressure on benthic microalgal diversity

Benthic microalgae and the herbivores Idothea chelipes and Littorina littorea were used as an experimental model system to study the effect of herbivore type on primary producer diversity.

Effects of Nutrient Enrichment on Microalgal Community Composition in a Coastal Shallow-water Sediment System: An Experimental Study

The effect of increased concentrations of inorganic nitrogen and phosphorus on microalgal community composition and the question has been raised whether an increasing eutrophication in the marine environment, implying changed ratios of nutrient supply, is currently changing the basis for the pelagic food web.

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.

Marine diversity shift linked to interactions among grazers, nutrients and propagule banks

A large-scale field survey and factorial field experiments indicated that grazers maintain the fucoid community through selective consumption of annual algae, implying a novel role of propagule banks for community regulation and ecosystem response to marine eutrophication.

A habitat matrix conceptual model for stream periphyton

In this paper we suggest a conceptual model for the evaluation of periphyton communities in unshaded temperate streams based on the primary habitat variables of flood disturbance, nutrient resource
