Effects of UV-B radiation and simulated herbivory on phlorotannins in the brown alga Ascophyllum nodosum
Models and experiments seelung to explain intraspec~f~c variation in brown algal phlorotannins (polyphenolics) have mainly focused on the effect of 2 factors, herbivory and resource availabilityExpand
Spatial and temporal variation in settlement and recruitment of the intertidal barnacle Semibalanus balanoides (L.) (Crustacea: Cirripedia) over a European scale
Variation in the level of settlement and recruitment in the intertidal barnacle Semibalanus balanoides was studied using a hierarchical sampling programme. The effect of three spatial scales, 10s ofExpand
Small-scale disturbance in a stable canopy dominated community: implications for macroalgal recruitment and growth
The long-living species Ascophyllum nodosum dominates the mid-shore of sheltered rocky sites in NW Europe, forming near-monospecific stands. We aimed to determine the effects of small-scaleExpand
Novel chemical weapon of an exotic macroalga inhibits recruitment of native competitors in the invaded range
Summary 1. Allelopathy is an important non-resource interaction in terrestrial plant communities that may affect invasions by non-indigenous plants. The ‘novel weapons hypothesis’ (NWH) predicts thatExpand
Effects of small-scale disturbances of canopy and grazing on intertidal assemblages on the Swedish west coast
The effects of small-scale disturbances (80×30-cm plots) of canopy and grazers on intertidal assemblages were investigated in this 4-year experiment on sheltered rocky shores on the Swedish westExpand
Seaweed defence against bacteria: a poly-brominated 2-heptanone from the red alga Bonnemaisonia hamifera inhibits bacterial colonisation
It has previously been shown that the red alga Bonnemaisonia hamifera is less fouled by bacteria relative to co-occurring seaweeds and that surface extracts of B. hamifera inhibit bacterial growth atExpand
The interactive effects of adult canopy, germling density and grazing on germling survival of the rockweed Ascophyllum nodosum
Mortality soon after settlement is typically high and spatial distribution of germlings is usually very variable in seaweeds. This is the case for Ascophyllum nodosum (L.) Le Jol, which is a veryExpand
Predator lipids induce paralytic shellfish toxins in bloom-forming algae
Significance We report the chemical basis for a critical question in ocean science: how do single-celled algae, which are responsible for almost half of Earth's photosynthesis, sense theirExpand
Antifouling compounds from the sub-arctic ascidian Synoicum pulmonaria: synoxazolidinones A and C, pulmonarins A and B, and synthetic analogues.
The current study describes the antifouling properties of four members belonging to the recently discovered synoxazolidinone and pulmonarin families, isolated from the sub-Arctic sessile ascidianExpand
The Bromotyrosine Derivative Ianthelline Isolated from the Arctic Marine Sponge Stryphnus fortis Inhibits Marine Micro- and Macrobiofouling
The inhibition of marine biofouling by the bromotyrosine derivative ianthelline, isolated from the Arctic marine sponge Stryphnus fortis, is described. All major stages of the fouling process areExpand
