Chemical defence against bacteria in the red alga Asparagopsis armata: linking structure with function
Results indicate that halogenated metabolites of Asparagopsis armata may be important in reducing epiphytic bacterial densities, in a novel ecological test of algal natural products. Expand
The protein content of seaweeds: a universal nitrogen-to-protein conversion factor of five
This article systematically analysed the literature to assess the approaches and methods of protein determination and to provide an evidence-based conversion factor for nitrogen to protein that is specific to seaweeds. Expand
Chemical mediation of bacterial surface colonisation by secondary metabolites from the red alga Delisea pulchra
The ability to swarm was widespread among these surface associated marine bacteria, suggesting that swarming may be ecologically important in these systems, and differential inhibition of different bacterial isolates or phenotypes by furanones should have strong effects on the species composition of the bacterial community on the alga's surface.

A new method for determining surface concentrations of marine natural products on seaweeds
A new technique for determining the concentration of natural products on the surface of marine algae, which suggests that the procedure is more broadly applicable for the quantification of non-polar surface metabolites on seaweeds, and other organisms with resistant surface cells. Expand
Suspended sediment grain size and mineralogy across the continental shelf of the Great Barrier Reef: Impacts on the physiology of a coral reef sponge
Declining water quality associated with increased suspended sediments has been closely linked to the reduced health status of benthic marine ecosystems and their associated organisms, includingExpand
Quorum Sensing Antagonism from Marine Organisms
The secondary metabolites manoalide, manoAlide monoacetate, and secomanoalide isolated from the sponge showed strong QS inhibition of a lasB::gfp(ASV) fusion, demonstrating the potential for further identification of specific QS antagonists from marine organisms. Expand
Total lipid and fatty acid composition of seaweeds for the selection of species for oil‐based biofuel and bioproducts
The results support macroalgae (seaweeds) as a biomass source for oil‐based bioproducts including biodiesel and quantified within species variation of fatty acids across locations and sampling periods supporting either environmental effects on quantitative fatty acids profiles, or genotypes with specific quantitative fatty acid profiles, thereby opening the possibility to optimize the fatty acid content and quality for oil production through specific culture conditions and selective breeding.

Larval settlement of the common Australian sea urchin Heliocidaris erythrogramma in response to bacteria from the surface of coralline algae
It is concluded that the bacterial community on the surface of coralline algae is important as a settlement cue for H. erythrogramma larvae and an example of the emerging integration of molecular microbiology and more traditional marine eukaryote ecology. Expand
Broad spectrum effects of secondary metabolites from the red alga delisea pulchra in antifouling assays
Activity of the D. pulchra metabolites was comparable to that of the heavy metals and biocides currently used in antifouling paints, however, no single compound was most active in all tests and some meta... Expand
