“…In addition, the positions of mangrove trees and canopy gaps as well as light penetration are also likely related to the abundance and distribution of the macroalgal assemblage. The mangrove trees were sparse at Station 1 but were dense at Stations 2 and 3 (Kaleem et al 2015). This pattern could be of paramount importance by affecting the shading of the forest floor by preventing light penetration and eventually promoting the homogenous distributions of red algae (Karsten et al 1994).…”

Abstrak: Bakau menyokong himpunan kepelbagaian "epibiont" macroalgal atas akar dan batang terapung pokok bakau. Makroalga membekalkan nutrien kepada pengguna utama dalam rantaian makanan akuatik dan telah dilaporkan menjadi penyumbang besar kepada ekosistem marin. Kepelbagaian spesies, biomass, dan ciri-ciri habitat makroalga bakau telah dikaji di tiga stesen bakau di muara Sibuti, Sarawak, Malaysia, dari bulan November 2012 hingga Oktober 2013. Tiga kumpulan makroalga direkodkan dan telah didapati tumbuh pada akar terapung pokok bakau, iaitu Rhodophyta (Caloglossa ogasawaraensis, Caloglossa adhaerens, Caloglossa stipitata, Bostrychia anomala, dan Hypnea sp.), Chlorophyta (Chaetomorpha minima dan Chaetomorpha sp.), dan Phaeophyta (Dictyota sp.). Biomass makroalga tidak dipengaruhi (p>0.05) mengikut musim di habitat hutan bakau. Spesies makroalga iaitu Hypnea sp. menyumbang biomass yang paling tinggi di kedua-dua Stesen 1 (210.56 mg/cm 2 ) dan Stesen 2 (141.72 mg/cm 2 ), manakala biomass tertinggi disumbangkan oleh B. anomala (185.89 mg/cm2) di Stesen 3. Kajian ini menunjukkan bahawa taburan dan himpunan spesies daripada makroalga bakau dipengaruhi oleh parameter alam sekitar seperti nutrien dari air, pepejal terlarut, dan kemasinan di habitat muara bakau Sibuti, Sarawak.Kata kunci: Makroalga, Bostrychia anomala, Biomass, Bakau, Sarawak Abstract: Mangroves support diverse macroalgal assemblages as epibionts on their roots and tree trunks. These algae provide nutrients to the primary consumers in the aquatic food web and have been reported to be substantial contributors to marine ecosystems. The species diversity, biomass, and habitat characteristics of mangrove macroalgae were investigated at three stations in the Sibuti mangrove estuary, Sarawak, Malaysia, from November 2012 to October 2013. Three groups of macroalgae were recorded and were found to be growing on mangrove prop roots, namely Rhodophyta (Caloglossa * 2 ) at Station 3. This study shows that the species distribution and assemblages of mangrove macroalgae were influenced by environmental parameters such as water nutrients, dissolved solids, and salinity in the estuarine mangrove habitats of Sibuti, Sarawak.

“…Hence, the forest can be classified under class 3 according to Watson (1928). The estuary is semi-diurnal, and the tidal range varies between 0.2 to 2.0 m during neap and spring tide, respectively (Hoque et al 2015b;Kaleem et al 2015). …”

“…Conversely, the lowest density was found X. granatum (44 ind/ha) ( Table 3). Shah et al (2016); Dimalen and Rojo (2018) revealed that X. granatum had a low density. The low density is due to highly exploited.…”

Abstract. Imamsyah A, Arthana IW, Astarini IA. 2020. The influence of physicochemical environment on the distribution and abundance of mangrove gastropods in Ngurah Rai Forest Park Bali, Indonesia. Biodiversitas 21: 3178-3188. Ngurah Rai Forest Park is the widest mangrove ecosystem in Bali that close to the business center and tourism area. The strategic location of the Ngurah Rai Forest Park is estimated to produce anthropogenic waste that can disrupt the gastropod population and stability of the mangrove ecosystems. This study aims to analyze the mangrove density, distribution, and abundance of gastropods based on the quality of the biophysical environment. Mangrove data collection was carried out using a plot transect of 10 m x 10 m, 5 m x 5 m, and 1 m x 1 m. Meanwhile, samples gastropods were collected on a plot transect of 0.5 m x 0.5 m in plot transect of 5 m x 5 m. A total of 11 gastropods species and 6 mangrove species were recorded in this study. The dominant gastropods species found were Assiminea brevicula (28 ind/m2). Species mangrove of Sonneratia alba and Rhizophora apiculata found were in all study sites with tree density values of 1000 ind/ha. Subsequently, the ecological index calculation results show that the diversity index (H’) (2.89-3.2), evenness index (E) (0.87-0.93), and dominance index (C) (0.12-0.17). Based on the Principal Component Analysis (PCA) found was Assiminea brevicula spread on sand and silt substrates and adaptive to the temperature condition, salinity, pH, and dissolved oxygen. Furthermore, other analysis results showed that Cerithidea cingulata, Cerithidea quadrata, Littoraria articulata, and Littoraria scabra were found on clay substrate with high C-organic content. In conclusion, gastropods are evenly distributed and no species dominate the ecosystems.

“…Sampling was conducted to estimate stem density (number of stems/0.01 ha) and basal area (m 2 /0.01 ha) as parameters. In this study, a minimum distance of 10 m x 10 m was chosen to developed sampling plots according to a study by Shah, Mustafa Kamal, Rosli, Hakeem, & Hoque (2016). The measurement included diameter at breast height (DBH), seedling counting, rubbish observation and the distance (m) between the plots and the walkway and to the sea.…”

Mangroves critically require conservation activity due to human encroachment and environmental unsustainability. The forests must be conserving through monitoring activities with an application of remote sensing satellites. Recent high-resolution multispectral satellite was used to produce Normalized Difference Vegetation Index (NDVI) and Tasselled Cap transformation (TC) indices mapping for the area. Satellite Pour l’Observation de la Terre (SPOT) SPOT-6 was employed for ground truthing. The area was only a part of mangrove forest area of Tanjung Piai which estimated about 106 ha. Although, the relationship between the spectral indices and dendrometry parameters was weak, we found a very significant between NDVI (mean) and stem density (y=10.529x + 12.773) with R2=0.1579. The sites with NDVI calculated varied from 0.10 to 0.26 (P1 and P2), under the environmental stress due to sand deposition found was regard as unhealthy vegetation areas. Whereas, site P5 with NDVI (mean) 0.67 is due to far distance from risk wave’s zone, therefore having young/growing trees with large lush green cover was regard as healthy vegetation area. High greenness indicated in TC means, the bands respond to a combination of high absorption of chlorophyll in the visible bands and the high reflectance of leaf structures in the near-infrared band, which is characteristic of healthy green vegetation. Overall, our study showed our tested WV-2 image combined with ground data provided valuable information of mangrove health assessment for Tanjung Piai, Johor, Malay Peninsula.
