Effects of UV-B radiation and simulated herbivory on phlorotannins in the brown alga Ascophyllum nodosum
The results imply that phlorotannins can function as inducible screens against harmful UV radiation, supporting the notion that small marine herbivores in general are tolerant to chemical defenses of algae.
Low-crested coastal defence structures as artificial habitats for marine life: Using ecological criteria in design
Spatial and temporal variation in settlement and recruitment of the intertidal barnacle Semibalanus balanoides (L.) (Crustacea: Cirripedia) over a European scale
Habitat and feeding preferences of crustacean mesoherbivores inhabiting the brown seaweed Ascophyllum nodosum (L.) Le Jol. and its epiphytic macroalgae
An ecological perspective on the deployment and design of low-crested and other hard coastal defence structures

The demography of the brown alga Ascophyllum nodosum was analyzed with a matrix popu- lation model and the main result was that growth to larger sizes or remaining in the same class contributed more to X, than repro- duction, which was valid for all levels of XA investigated.
A continental scale evaluation of the role of limpet grazing on rocky shores
A clear trophic control of an ecosystem is shown in that grazing by limpets not only determines macroalgal abundance overall but also modifies ecosystem stability via variability in cover of algae.
Shift in seagrass food web structure over decades is linked to overfishing
Clear evidence is found that a shift in seagrass food web structure has taken place over the last 3 decades, with lack of grazers in concert with eutrophication most likely contributed to the over- growth by filamentous algae and disappearance of the seagRass on the Swedish west coast.
Seed rafting as a dispersal strategy for eelgrass (Zostera marina)
Effects of wave exposure and depth on biomass, density and fertility of the fucoid seaweed Sargassum polyceratium (Phaeophyta, Sargassaceae)
It is concluded that both wave exposure and depth affect population structure and thalli were generally bigger and total biomass higher in the more exposed bay(s) and in shallower water, contradicting the general pattern in macroalgae of reduced size and biomass with increasing wave exposure.
