Article
Full-text available
The effects of small-scale disturbances, such as monsoon, are understudied in tropical regions. The storms associated with monsoon events not only modify the local macroalgal community structure, but also reveal the continuation of short-term recolonisation. Thus, this study aims to determine the variation in species, assemblage and cover of macroa...
Article
The Asia-Pacific blue carbon ecosystems named mangroves, seagrass meadows and salt marsh plays an important role in climate change mitigation and adaptation. However, still data gaps exist in this region to understand the blue carbon dynamic process and how future climate change will impact it. The special feature aims to fill the gaps and contribu...
Article
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 contributin...
Article
Seagrasses have the ability to contribute towards climate change mitigation, through large organic carbon (Corg) sinks within their ecosystems. Although the importance of blue carbon within these ecosystems has been addressed in some countries of Southeast Asia, the regional and national inventories with the application of nature-based solutions ar...

Seagrasses have the ability to contribute towards climate change mitigation, through large organic carbon (Corg) sinks within their ecosystems. Although the importance of blue carbon within these ecosystems has been ad dressed in some countries of Southeast Asia, the regional and national inventories with the application of nature-based solutions a...
Article
Ostracods and foraminifera are excellent indicators of environmental change and can act as proxies for the presence of seagrass meadows. These proxies have been under-utilized in vulnerable coastal ecosystems in South-east Asia, and the fundamental habitat and environmental parameters required for such application in environmental monitoring have n...
Article
Coralline macroalgae are globally distributed rhodopyhtes that remove carbon from their immediate environment and transform it into carbonate sediments through the senescence of their calcified tissues. In this study, the calcium carbonate (CaCO3) stocks in the tissue of Jania adhaerens and sediments in Tanjung Adang Shoal, Johor were quantified fo...
Article
The effects of cyclical disturbances towards macroalgal community structure could reveal the progression of short-term colonisation but are understudied in tropical settings, especially in Malaysia. The storms associated with monsoon events modify the local macroalgal community structure, and this study aims to determine the variation in species, a...
Article
The high organic carbon (OC) stores in seagrass meadows have led to their recognition as significant Blue Carbon sinks, though the diagenetic conditions that enable OC retention in seagrass soils remain poorly understood. In this study, seagrass soils were sampled from a Posidonia australis meadow in Oyster Harbour (Albany; south-western Australia)...
Article
Full-text available
This paper presents data on nitrogen characteristics in a tropical seagrass meadow located in Sungai Pulai estuary (Johor, Malaysia) and is related to the article "Nitrogen dynamics in tropical seagrass meadows under heavy anthropogenic influence" [1]. Field sampling conducted from August 2015 to May 2016 aimed to collect sediments and seagrass tis...
Article
Nitrogen is essential for seagrass productivity but excesses in nitrogen exposure contribute to declines in meadow health. This study reports baseline data of bulk nitrogen loadings and contents in surficial sediments and seagrass tissues to determine the extent of nitrogen inputs in meadows of Sungai Pulai estuary (Johor, Malaysia). The sediment c...
Article
Full-text available
Policies aiming to preserve vegetated coastal ecosystems (VCE; tidal marshes, mangroves and seagrasses) to mitigate greenhouse gas emissions require national assessments of blue carbon resources. Here, we present organic carbon (C) storage in VCE across Australian climate regions and estimate potential annual CO2 emission benefits of VCE conservati...
Article
In this paper, we report the occurrence of Halophila decipiens Ostenfeld found growing in an intertidal environment. At the study site of Sungai Bahan estuary located along the Straits of Johor (Malaysia), the seagrass grew sparsely in the lower littoral zone of the mangrove coastline. Forming discontinuous patches, the seagrass was fully exposed o...
Article
The chlorophyte genus Halimeda is common in tropical waters but gaps still exist in the understanding of the biogeographical distributions of its species in Southeast Asia, particularly in Malaysia. During a study into the ecological functioning of reefs in a marine park (the Sembilang–Seri Buat group of islands, Pahang, Malaysia) along the eastern...
Article
Full-text available
Seagrass ecosystems are considered as major blue carbon sinks, thus contributing directly to the mitigation of climate change by storing carbon in their habitats. However, empirical data for carbon stocks in Malaysia seagrass meadow sediment remain unreported in a standardised format. This paper presents data on organic (OC) and inorganic carbon (I...
Chapter
Kajian ini dijalankan bertujuan untuk mengumpulkan rekod terdahulu dan mengenal pasti kawasan yang masih diliputi oleh rumput laut dan kawasan rumput laut yang belum direkodkan di Malaysia. Beberapa kawasan rumput di Malaysia laut telah dipilih untuk ditinjau. Selain itu, hasil kajian dapat dimanfaatkan oleh pihak-pihak berkaitan dalam menjaga dan...
Article
Full-text available
Seagrass ecosystems contain globally significant organic carbon (C) stocks. However, climate change and increasing frequency of extreme events threaten their preservation. Shark Bay, Western Australia, has the largest C stock reported for a seagrass ecosystem, containing up to 1.3% of the total C stored within the top metre of seagrass sediments wo...
Article
Full-text available
Biotic and abiotic factors influence the accumulation of organic carbon (Corg) in seagrass ecosystems. We surveyed Posidonia sinuosa meadows growing in different water depths to assess the variability in the sources, stocks and accumulation rates of Corg. We show that over the last 500 years, P. sinuosa meadows closer to the upper limit of distribu...
Article
Coastal vegetated ecosystems play an important role in carbon cycling and bacterial communities inhabiting coastal sediments are responsible for the remineralization and processing of organic carbon (OC). We collected 1 m-long sediment cores in Posidonia seagrass meadows from coastal and estuarine sites in Australia that differed in their sedimenta...
Article
The actual estimates of carbon stocks beneath seagrass meadows worldwide are derived from few data, resulting in a tendency to generalize global carbon stocks from a very limited number of seagrass habitats. We surveyed Posidonia oceanica and Posidonia sinuosa meadows along depth-induced gradients of light availability to assess the variability in...
Article
Full-text available
The recent focus on carbon trading has intensified interest in 'Blue Carbon'-carbon sequestered by coastal vegetated ecosystems, particularly seagrasses. Most information on seagrass carbon storage is derived from studies of a single species, Posidonia oceanica, from the Mediterranean Sea. We surveyed 17 Australian seagrass habitats to assess the v...
Article
Full-text available
A laboratory based experiment was performed on leaves of the seagrass Halophila ovalis to elucidate its photosynthesis versus irradiance (P-I) relationships. Plant samples were sourced from a low water level seabed off the Teluk Kemang coast (2 ° 30′N, 101 ° 45′E) in Negeri Sembilan, Malaysia. Plants growing naturally from this area as well as thos...
