Abstract Global seaweed carbon sequestration estimates are currently taken as the fraction of net primary production (NPP) exported to deep ocean. However, this perspective does not account for CO2 from consumption external subsidies. Here, we clarify: (i) role export relative ecosystem (NEP) a closed system and one more likely open subsidies; (ii) importance subsidies by compiling published NEP seaweed-dominated ecosystems; (iii) discuss their impact on global balance other constraints...
Habitat forming 'ecosystem engineers' such as kelp species create complex habitats that support biodiverse and productive communities. Studies of the resilience stability ecosystem engineers have typically focussed on role external factors disturbance. However, their population dynamics are also likely to be influenced by internal processes, environmental modifications caused engineer feedback affect own demography (e.g. recruitment, survivorship). In numerous regions globally, forests...
Abstract The biodiversity benefits of kelp aquaculture and afforestation are increasingly acclaimed as the industry continues to grow develop globally, however, whether farmed can provide this ecosystem service remains unclear. Using peer-reviewed literature, we evaluated farms benefits, identified only 23 studies that discussed effects on biodiversity, half which were broad reviews assessed concept ‘biodiversity’ peripherally (e.g. did not focus specific responses or taxa). There is also a...
Abstract Tasmania is an island state in south-eastern Australia that has a long and rich history of seaweed use, research, development. It cool-temperate system with 750 macroalgal species currently described. Tasmanian Aboriginal peoples have lived on this land for at least 40,000 years utilising as food, shelter, water carriers medicine, well ceremonial reasons. Modern taxonomic investigations began French naturalist Jacques-Julien Houtou de La Billardière 1791, there are 184 type...
Abstract There is increasing interest in mitigating the loss of kelp forests through restoration, but this has received scant attention relative to other coastal habitats. We evaluate current knowledge centered on key restoration principles provide guidelines for best practice restoration. The cause and scale degradation fundamental determining if can be restored methods required promote reestablishment. Removal stressors may adequate achieve goals where not too widespread or acute....
Abstract Kelp forests around the world are under increasing pressure from anthropogenic stressors. A widespread consequence is that in many places, complex and highly productive kelp habitats have been replaced by structurally simple less turf algae habitats. Turf resist re‐establishment of via recruitment inhibition; however, little known about specific mechanisms involved. One potential factor chemical environment within into which propagules settle develop. Using laboratory trials, we...
Ecosystem engineers are species that influence the abiotic and biotic environment around them may assist restoration of associated species, including other habitat‐forming species. We deployed an array 28 artificial reefs with transplanted Ecklonia radiata , dominant canopy‐forming kelp across southern Australia, to investigate how patch size density E. influenced establishment communities plants animals. Many were rapidly colonized by Ostrea angasi a critically depleted reef‐forming oyster....
Habitat‐forming ecosystem engineers are the foundation of many marine ecosystems where they support diverse and productive food‐webs. A reduction in their patch size or density may affect productivity, biodiversity stability these ecosystems. We determined effects different densities sizes Ecklonia radiata (the dominant kelp southern Australia) on secondary species richness, diversity community structure understory epifaunal invertebrates how associated environmental covariates modified by...
Kelp forests in many regions are experiencing disturbance from anthropogenic sources such as ocean warming, pollution, and overgrazing. Unlike natural disturbances storms, often manifest press perturbations that cause persistent alterations to the environment. One consequence is some kelp becoming increasingly sparse fragmented. We manipulated patch size of Ecklonia radiata over 24 mo simulate habitat fragmentation assessed how this influenced demography macro- microscopic juvenile within...
The kelp, Ecklonia radiata, is an abundant subtidal ecosystem engineer in southern Australia. Density-dependent changes the abiotic environment engineered by may feedback to affect reproduction and subsequent recruitment. Here, we examined: 1) how reproductive capacity of individuals field (zoospores released · mm
The ability to successfully transplant adult kelp has applications not only for ecological experiments, but also habitat conservation and restoration projects. However, approaches the long‐term transplanting of (especially stalked or ‘stipitate’ species), communication these methods, been relatively haphazard, often due poor results excessive mortality. Here, we provide a brief describe method effectively stipitate Ecklonia radiata —the most widespread abundant in Australasia—and which...

Abstract Marine imagery is a comparatively cost-effective way to collect data on seafloor organisms, biodiversity and habitat morphology. However, annotating these images extract detailed biological information time-consuming expensive, reference libraries of consistently annotated are rarely publicly available. Here, we present the Antarctic Seafloor Annotated Imagery Database (AS-AID), result multinational collaboration collate annotate regional datasets from 19 research cruises between...

Abstract The comment qualitatively suggests that seaweed ecosystems are global carbon sinks. This was in contradiction to the article showed on average measurably sources within canopy. Furthermore, this amplified by remineralization of a large fraction exported production, as estimated from published parameters. It appeared comments’ conclusion mistaken two standpoints.

Abstract Ecosystem engineers often exert strong effects on the recruitment of other species through modification local abiotic and biotic environment. In 2015, artificial reefs in eastern Tasmania (− 42.64693, 148.01481) spanning seven different patch sizes (0.12–7.68 m 2 ) supporting four densities transplanted kelp ( Ecklonia radiata at 0, 4.1, 8.2 16.4 −2 were used to determine how size density this ecosystem engineer influenced microphytobenthic (MPB) algae, a secondary engineer, mussel...
Abstract The patch dynamics of foundation species profoundly affects community assembly and thus has important implications for ecosystem restoration. However, it is unclear how restored kelp patches that vary in size density will influence the establishment mid‐trophic level (MTL) macroinvertebrates, a key functional group coastal ecosystems. Artificial reefs with transplants canopy‐forming kelp, Ecklonia radiata , were used to quantify effect on densities MTL macroinvertebrates (primarily...
