“…In a mangrove from Baja California, Mexico, 21 cyanobacterial species, including Heteroleibleinia sp. and Johannesbaptistia sp., have been found either growing on Avicennia germinans pneumatophores and Rhizophora mangle aerial roots or on epiphytic algae (Pérez-Estrada et al 2012). Potts (1979) detected cyanobacterial growth zonation in Avicennia marina pneumatophores, with Scytonema sp.…”

Mangroves are subject to the effects of tides and fluctuations in environmental conditions, which may reach extreme conditions. These ecosystems are severely threatened by human activities despite their ecological importance. Although mangroves are characterized by a highly specialized but low plant diversity in comparison to most other tropical ecosystems, they support a diverse microbial community. Adapted microorganisms in soil, water, and on plant surfaces perform fundamental roles in nutrient cycling, especially nitrogen and phosphorus. Cyanobacteria contribute to carbon and nitrogen fixation and their cells act as phosphorus storages in ecosystems with extreme or oligotrophic environmental conditions such as those found in mangroves. As the high plant productivity in mangroves is only possible due to interactions with microorganisms, cyanobacteria may contribute to these ecosystems by providing fixed nitrogen, carbon, and herbivory-defense molecules, xenobiotic biosorption and bioremediation, and secreting plant growth-promoting substances. In addition to water, cyanobacterial colonies have been detected on sediments, rocks, decaying wood, underground and aerial roots, trunks, and leaves. Some mangrove cyanobacteria were also found in association to algae or seagrasses. Few studies on mangrove cyanobacteria are available, but together they have reported a substantial number of species in these ecosystems. However, the cyanobacterial diversity in this biome has been traditionally underestimated. Though mangrove communities generally host cyanobacterial taxa commonly found in marine environments, unique microhabitats found in mangroves Communicated by Anurag chaurasia.

“…Researchers have also found higher amounts of mangrove macroalgae during the summer season (Steinke & Naidoo 1990), which was found to be influenced by nutrient availability, temperature, and light intensity. In contrast, studies by Perez-Estrada et al (2012), Nedumaran and Perumal (2009), Liu et al (2001), El-Sharouny et al (2001), and Lin et al (1997 found that mangrove macroalgae grow throughout the year, and seasonal influences on their growth were not noticed. It has been observed that the three stations in the Sibuti mangroves have their own biotic and abiotic factors that influence the species abundance of macroalgae (Broderick & Dawes 1998).…”

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.

Cyanobacteria are one of the most important groups of photoautotrophic organisms, contributing to carbon and nitrogen fixation in mangroves worldwide. They also play an important role in soil retention and stabilisation and contribute to high plant productivity through their secretion of plant growth-promoting substances. However, their diversity and distribution in Malaysian mangrove ecosystems have yet to be studied in detail, despite Malaysia hosting a significant element of remaining mangroves globally. In a floristic survey conducted in Penang, peninsular Malaysia, 33 morphospecies of periphytic cyanobacteria were identified and described for the first time from a mangrove ecosystem in Malaysia. Sixteen genera, comprising Aphanocapsa, Chroococcus, Chroococcidiopsis, Cyanobacterium, Desmonostoc, Geitlerinema, Leptolyngbya, Lyngbya, Microcystis, Myxosarcina, Oscillatoria, Phormidium, Pseudanabaena, Spirulina, Trichocoleus and Xenococcus, were obtained from field material growing on diverse natural and artificial substrata. Oscillatoriales was the dominant order with Phormidium the dominant genus at nine of the 15 sampling sites examined. Three of the morphospecies, Aphanocapsa cf. concharum, Xenococcus cf. pallidus and Oscillatoria pseudocurviceps, are rare and poorly known morphospecies worldwide. Chroococcus minutus, Phormidium uncinatum, P. amphigranulata, and some species of Oscillatoriales are considered as pollution indicator species. This study provides important baseline information for further investigation of the cyanobacterial microflora present in other mangrove areas around Malaysia. A complete checklist will enhance understanding of their ecological role and the potential for benefits arising from useful secondary metabolites or threats via toxin production to the ecosystem.
