Environmental and Biotic Drivers of Seaweed–Bacterial Interactions: Insights into the Seaweed Holobiont
Seaweeds are host to a wide variety of microbes with which they form chemically mediated relationships, operating as a unified holobiont - an integrated functional unit. Host fitness is reliant on this symbiosis, with interactions from epiphytic bacteria necessary for the correct physiological …

Floating seaweed as ephemeral neustonic habitat
… demonstrate that the habitat formed by floating seaweeds is very complex. Although the presence of floating seaweeds in the neuston can, to a certain degree, be seasonally predicted (storms, seasonal release of fertile structures), the habitat that they form is still very patchy and unstable. …

Some South African red seaweed polysaccharides
… cellulose in land plants. Laminarin from brown seaweeds and Floridean starch from certain red algae are reserve polysaccharides while algihates (from brown seaweeds) and carrageenin and agar (from red seaweeds) are structural polyrsaccharides. The most common encountered algal polycysaccharides, …

Scotland’s blue carbon: the contribution from seaweed detritus
The ecological and biological importance as well as economic, and cultural value of macroalgae is becoming more prominent. Introduction of the term ‘blue carbon’ (BC) has drawn attention to natural coastal habitats and their capacity to fix CO2. The overall aim of this thesis was to place the …

Seaweed : a Web application for designing economic games
Seaweed is a web application for experimental economists with no programming background to design two-player symmetric games in a visual-oriented interface. Games are automatically published to the web where players can play against each other remotely and game play is logged so that the game's …

The future social implications of seaweed cultivation for bioenergy production
Macroalgae or seaweed cultivation is a promising growing industry in Northern Europe due to the large range of products that can be derived from the seaweed biomass. One of these uses is the production of bioenergy, which could provide many advantages in the current context of decarbonisation. …

The biogeography and biodiversity of the Namibian intertidal seaweed flora
… out on the Namibian coast. With respect to seaweeds in particular there have been a number of species lists and shore descriptions, but very little research into the biogeography, diversity or ecology. One of the reasons for the lack of research is probably that much of the 1500 km coast is …

PHOTOADAPTIVE RESPONSES IN THE TROPICAL BROWN SEAWEED, LOBOPHORA VARIEGATA (LAMOUR) WOMERS
… relationships of the tropical brown seaweed, Lobophora variegata. Pigment analyses were performed on samples collected from a series of depths between 9 and 49m. Chlorophyll a, chlorophyll c, and fucoxanthin were constant on a thallus weight basis, but showed small decreases when …

Ecophysiological studies of three South African Ulva species from integrated seaweed
In South Africa, Ulva cultivation is of paramount importance to the marine aquaculture industry. Three local Ulva species (Ulva lactuca Linnaeus, Ulva rigida C. Agardh and Ulva capensis Areschoug) were selected for this research. The first two are currently cultivated on abalone farms for abalone …

Seaweed diversity in Saldanha Bay and the effects of human activities
Several accounts have been produced on the seaweeds of the west coast including the Saldanha and Langebaan System, but none has looked at how human activities may have affected the seaweed diversity of Saldanha Bay. The major human activities in the Bay include shipping and mariculture. The major …

Seaweed as a value-added product for the food and drink sector
… enhanced nutritional and therapeutic benefits. Seaweeds are a product that could help meet these needs. Seaweeds grow naturally without the need for freshwater and fertilisers and do not compete for traditional agricultural land. The environmental impacts of harvesting wild seaweeds or growing …

Shallow subtidal seaweed communities of the Agulhas Marine Province of South Africa
Several aspects of seaweed ecology are poorly studied and documented in South Africa, especially the subtidal algal communities along the south coast. This study aims to investigate these communities where few other studies have been conducted. Sampling of shallow subtidal seaweed communities was …
