Restoring and valuing global kelp forest ecosystems
Kelp forests cover ~30% of the world’s coastline and are the largest biogenic marine habitat on earth. Across their distribution, kelp forests are essential for the healthy functioning of marine ecosystems and consequently underpin many of the benefits coastal societies receive from the ocean. …

A glade in the kelp forest: socio-spatial opportunities for multi-trophic aquaculture Hout Bay, South Africa
… area), with a specific focus on implementing a kelp aquaculture framework. Kelp is an ecosystem driver, filter feeder and a versatile product. In South Africa, kelp forests are present along the West Coast due to the upwelling of the Benguela system in which cold, nutrient-rich waters from the …

Mapping and assessing ecosystem threat status of South African kelp forests
At a global scale, kelp forests play a significant ecological, social and economic role through their provision of ecosystem services. South African kelp forests are no exception and recent studies have established their value. To maintain these benefits, informed management is needed. An …

Changes in food web structure and energy flow in kelp forest ecosystems on the south-west coast of South Africa following the invasion of Jasus lalandii
… state dominated by lobsters, sessile species, kelp and understory foliose algae. Using the trophic modelling software Ecopath with Ecosim, baseline models of the pre- and Post-invasion systems were created to better understand trophic pathways between the two different states and assess how …

Stable isotope ecology of South African kelp forests
Kelp forests are some of the most productive coastal ecosystems in the world and provide numerous ecosystem goods and services. Where they occur, they play a key role in coastal ecology and local fisheries. In South Africa, Ecklonia maxima and Laminaria pallida form kelp forests which support …

A study on the behaviour and reproduction of the weedsucker, Eckloniaichthys scylliorhiniceps (Smith, 1943)
… lay between 120 and 150 eggs on the fronds of kelp. Reproduction is thought to take place year round. Further work needs to be conducted on predators of weedsuckers, tentatively suggested here to be diving birds (such as Phalacrocorax capensis) and mid-level benthic predators (such as Poroderma …

Benthic habitats in a tide-swept channel of the Pentland Firth and their potential responses to a tidal energy development
… tide-swept channels with a<br/>fringe of dense kelp forest along the shallow, sheltered waters of the channel, followed by a ’tran-sition zone’ dominated by foliose red algae in the mid-depth ranges and animal turf assemblages in the deeper, very tide-swept waters. Multivariate analyses …

Marine parasites in island-like disturbed habitats
… and both well connected and undisturbed (kelp forest). Overall, parasite diversity within host species was not significantly lower at vents, but the vent community had many fewer parasite species because there are fewvertebrate predator species (fish). Parasites with indirect (multi-host) …

Hydrodynamic and transport phenomena at the interface between flow and aquatic vegetation : from the forest to the blade scale
… scale, interactions between fluid motion and kelp produce a wide array of hydrodynamic and scalar transport phenomena. At the kilometer scale of the kelp forest, coastal currents transport nutrients, microorganisms and spores. But, kelp forests exert a drag force on currents, causing the flow …

Scotland’s blue carbon: the contribution from seaweed detritus

Physiological effects of climate change and estimations of carbon standing stock of southern Salish Sea kelps
Kelp forests are among the most diverse and productive ecosystems in the world, providing critical habitat for numerous ecologically and economically important species. However, kelps are at risk from climate change, particularly along the North American West Coast, demonstrating the need to …
