A preliminary study of carbon dioxide and methane emissions from patchy tropical seagrass meadows in Thailand [PDF]

PeerJ
Background Seagrass meadows are a significant blue carbon sink due to their ability to store large amounts of carbon within sediment. However, the knowledge of global greenhouse gas (GHG) emissions from seagrass meadows is limited, especially from ...

Functionally Rich Fish Assemblages Support Greater Rates of Multiple Ecological Functions in Seagrass Meadows [PDF]

Ecology and Evolution
Animals move between ecosystems, facilitating important ecosystem functions. The context, connectivity, and complexity of habitats alter faunal assemblages and associated ecological functions that regulate ecosystem structure, functioning, and resilience.

Seagrass meadows mixed with calcareous algae have higher plant productivity and sedimentary blue carbon storage [PDF]

Ecology and Evolution, 2022
Seagrass meadows capture and store large amounts of carbon in the sediment beneath, thereby serving as efficient sinks of atmospheric CO2. Carbon sequestration levels may however differ greatly among meadows depending on, among other factors, the plant ...

Seagrass Meadows: Prospective Candidates for Bioactive Molecules [PDF]

Molecules
Seagrass meadows consist of angiosperms that thrive fully submerged in marine environments and form distinct ecosystems. They provide essential support for many organisms, acting as nursery grounds for species of economic importance. Beyond their ecological roles, seagrasses and their associated microbiomes are rich sources of bioactive compounds with ...

Impacts of dredging and restoration on sedimentary carbon stocks in seagrass meadows of Pari Island, Indonesia [PDF]

Scientific Reports
The effects of dredging and restoration on carbon sequestration in seagrass sediments is not well understood. Our knowledge is derived from few studies conducted in areas affected by dredging or restoration, the majority of which are from temperate ...

Dugong dugon feeding in tropical Australian seagrass meadows: implications for conservation planning [PDF]

PeerJ, 2016
Dugongs (Dugong dugon) are listed as vulnerable to extinction due to rapid population reductions caused in part by loss of seagrass feeding meadows. Understanding dugong feeding behaviour in tropical Australia, where the majority of dugongs live, will ...

Seagrass restoration trials in tropical seagrass meadows of Kenya

Western Indian Ocean Journal of Marine Science, 2022
The degradation of seagrasses is becoming prevalent in the Western Indian Ocean (WIO) region due to anchor damage, sea urchin herbivory, extreme events such as cyclones and floods and anthropogenic factors such as pollution and sediment inflows. Consequently, there have been numerous efforts to advance the restoration of degraded seagrass beds in ...

The global distribution of seagrass meadows [PDF]

Environmental Research Letters, 2020
Abstract Seagrass meadows globally are under pressure with worldwide loss and degradation, but there is a growing recognition of the global importance of seagrass ecosystem services, particularly as a major carbon sink and as fisheries habitat.

Mapping of Subtidal and Intertidal Seagrass Meadows via Application of the Feature Pyramid Network to Unmanned Aerial Vehicle Orthophotos

Remote Sensing, 2021
Seagrass meadows are one of the blue carbon ecosystems that continue to decline worldwide. Frequent mapping is essential to monitor seagrass meadows for understanding change processes including seasonal variations and influences of meteorological and ...
