“…have a great capacity to absorb CO2. In such cases, seaweed farming is considered as a natural carbon stock (KRAUSE-JENSEN et al, 2016;ARINA et al, 2020). This potential has a clear implication in carbon sequestration and regulation of ocean acidification, generating benefits in climate regulation (CHUNG et al, 2011;CHUNG et al, 2013;CHUNG et al, 2017;HAN et al, 2013;MONGIN et al, 2016).…”

Marine macroalgae provide a variety of ecosystem services in the environmental, social and economic spheres. This study presents a qualitative assessment of the ecosystem services offered by marine macroalgae (cultivated and natural populations). Furthermore, it provides a better understanding of the benefits of macroalgae cultivated in a case study (Gracilaria birdiae) in a tropical area in Brazil. For this, a literature review was carried out using articles available on the internet (Web of Science, Science Direct, Scopus, Scielo and Google Scholar) published between 2009 and 2020, which addressed the ecosystem services associated with macroalgae. A total of 1,428 articles were analyzed, of which 163 reported some type of ecosystem service. The most registered service was regulation (30.1%), followed by provision (28.4%), support (28.0%) and cultural (13.5%). In the case study, 12 services were identified, five of which belonged to support, three to cultural, two to provision and two to regulation. Thus, both cultivated macroalgae and natural populations offer diverse ecosystem services that contribute to environmental improvement and play a positive role in the preservation and conservation of the environment and human well-being. In addition, the ecosystem services provided by macroalgae are fully aligned with several Sustainable Development Goals, especially SDGs 2, 3, 5, 8, 10, 12, 13 and 14, which encompass the three pillars of sustainability (environmental, social and economic).

“…The combined proportion of macroalgal‐ and seagrass‐derived OC is higher (20%–23%) in the Merambong shoal than in Tanjung Adang shoal, approximately 11%–15% (Figure 3), suggesting that autochthonous production is more characteristic of the OC stocks in Merambong shoal. Recent findings indicated seasonal variations of macroalgal inputs to the meadows in the estuary (Arina et al, 2020). It is likely that any autochthonously produced OM, as indicated by this variation in drift macroalgal deposits, is exported to deeper parts of the estuary and is consistent with reports of such a phenomenon (Ortega et al, 2019).…”

“…Since macroalgal growths in the estuary are dominated by epipelic and epilithic forms (Muta Harah et al, 2014), macroalgal‐derived OM would tend to be deposited on sediment surfaces and is subjected to drifting away from the beds or remineralization due to the relative lability of its detritus (Krause‐Jensen & Duarte, 2016). On the other hand, biogenic IC of macroalgal origin, specifically produced by corallines, contributed up to 147 g CaCO 3 m −2 in Tanjung Adang shoal (Arina et al, 2020). Calcifying systems produce CO 2 in the calcification process, and therefore calcifying macroalgae in the meadows may reduce the net OC sink capacity of the mixed‐macrophyte meadow (after Macreadie et al, 2017).…”

Mangroves, seagrasses and macroalgae form inter-connected coastal habitats.They are involved in the direct and indirect sequestration and accumulation of blue carbon and are recognized for their role in climate change mitigation.Macroalgae, though residing within or in close proximity to these ecosystems are, however, not perceived as contributing to blue carbon storage. Such habitat connectivity among the mangrove, seagrass, and macroalgal compartments complicates a straightforward assessment of blue carbon storage. In this study, we assessed the contributions of these macrophytes as endmembers to the bulk organic carbon (OC) stocks in surficial (top 30 cm) and deep (31-100 cm) sediment layers of seagrass beds within the Sungai Pulai estuary (Malaysia).Organic carbon stocks in the seagrass sediments ranged from 14.3 to 21.4 Mg OC ha À1 (surficial depths), and 137.9 ± 23.3 (mean ± SE) Mg OC ha À1 for the deep layer. Mangrove-derived matter contributed a maximum of 65% to the bulk OC pool. The existence of downcore variability indicated that macroalgae contributed up to 16% and were higher than seagrass sources (12%). Our results suggest that macroalgal-derived and mangrove-derived organic matter are important contributors to OC sequestration in the estuary. In view of the heterogeneous OC pool that contributes to bulk OC stocks, placing importance on only one OC source may construe an incomplete profile of habitat-specific capacity for OC storage. This has wider implications for understanding OC subsidies, the effects of which are particularly relevant when one considers the impacts of coastal land use changes on blue carbon storage.

“…同时, 海草床中也有部分植食动物, 在摄食纤维素含量较高且难以消化的海草叶片后, 会将叶片直接排泄出而留下附生藻类 [6,37] . 另外, 大型藻类在三种海草生境中对红树拟蟹守螺的食源贡献比例相近(27%~33%), 这可能是因为大型藻类容易受到潮汐的影响, 使其在海草床内具有较好的漂浮迁移能力 [38,39] , 在三种海草生境中分布较均匀, 导致红树拟蟹守螺取食到大型藻类的概率接近. 另外, 悬浮颗粒有机质(1.4%~6.8%)和沉积物有机质(1.4%~8.9%)在三种海草生境中对螺的食源贡献均相对较小, 可能是因为腹足类动物更多地是通过口齿进行摄食行为, 而较少地进行滤食行为 [40,41] .…”
