Photosynthetic and Stomatal Responses of Two Mangrove Species, Aegiceras corniculatum and Avicennia marina, to Long Term Salinity and Humidity Conditions

Mangrove species, viz., Avicennia officinalis, Avicennia marina var. acutissima, Avicennia marina (dwarf), Rhizophora mucronata, Sonneratia alba, Aegiceras corniculatum, Kandelia candel were chosen for measurement of height of the tree and girth or circumference. The sampling was random and at least 50 records were made. The girth is measured by the tape. The measurement of the height is made with the help of abny level. The Tables 1 to 8 records the values for girth, height and canopy cover as well as for correlation coefficient (r). There correlation between girth and canopy in all the species studied however in case of Avicennia officinalis and Aegiceras corniculatum girth and height show more co-relation than girth and C. cover. The positive co-relation observed between girth and canopy is more or less 0.7 except Avicennia marina (dwarf) Excoecaria agallocha and Aegiceras corniculatum. The co-relation is observed in girth and height is difficult to explain. This case is observed in Avicennia officinalis and Aegiceras corniculatum.

Background: Mangrove plant extracts are used in folkloric medicine as aphrodisiac, sedative, antioxidant, antimicrobial and antimalarial. Screening for antimicrobial, phytochemical and antioxidant activities of fourteen mangroves plant species (Aegiceras corniculatum, Acanthus ilicifolius, Avicennia alba, Avicennia marina, Avicennia officinalis, Bruguiera cylindrica, Bruguiera gymnorhiza, Ceriops tagel, Excoecaria agallocha, Kandelia candel, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, and Sonneratia caseolaris) in various solvents are reported in this work. Methods: The antimicrobial screening was carried out using agar well diffusion method. In this study, nine pathogenic strains were used, including three Gram-positive and six Gram-negative bacteria. Phytochemical screening, total flavonoids, total phenolic and antioxidant activity was tested by DPPH radical scavenging assay. Four phenolic compounds (gallic acid, vanillin, tannic acid and quercetin) were quantified by LC-MS/MS in selected mangrove species. Results: Antimicrobial screening showed Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis and Pseudomonas aeruginosa were most susceptible to ethyl acetate extract as compared to ethanol and methanol extract. Ethyl acetate extract of Avicennia marina and Bruguiera gymnorhiza showed strong antibacterial activity against Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis and Pseudomonas aeruginosa. Phytochemical analysis revealed the presence of saponins, phenolics, flavonoids, alkaloids, tannins, and terpenoids, which was found to be variable as per the solvent used for extraction. In addition, total phenolics and total flavonoids content with different solvents were found in the range of 11.08 to 196.76 mg GAE/g and 12.92 to 110.3 mg QE/g of extract respectively. Moreover, antioxidant capacities expressed in terms of IC50 (mg/mL) showed that methanol extract exhibited higher antioxidant capacity followed by ethanol extract. LC-MS/MS analysis showed gallic acid and tannic acid are present in higher concentration in Aegiceras corniculatum and Sonneratia caseolaris than other species. The vanillin and quercetin were found in the least concentration. Conclusion: Mangroves species are rich source of antioxidant, phenolics and antimicrobial compounds.

Mangrove forests are unique ecosystems that have ecological, biological and socio-economic functions. The function of mangrove forests on the environment is very important especially in the coastal and oceanic regions. Mangrove forests providers of wood, leaves as raw material for medicines, and natural dye. This study aims to inventory the diversity of species of mangrove vegetation in Mendalok Village, Sungai Kunyit Subdistrict, Mempawah Regency. The benefits of this study are to provide the data on mangrove forest vegetation as basic data for local government and related agencies in efforts to protect and preserve mangrove forests in Mendalok Village, Sungai Kunyit Subdistrict, Mempawah Regency.

Abstract. Raganas AFM, Hadsall AS, Pampolina NM, Hotes S, Magcale-Macandog DB. 2020. Regeneration capacity and threats to mangrove areas on the southern coast of Oriental Mindoro, Philippines: Implications to mangrove ecosystem rehabilitation. Biodiversitas 21: 3625-3636. Regeneration capacity is important as it determines the fate of an ecosystem. This study assessed six mangrove areas in the southern coast of Oriental Mindoro, Philippines to evaluate their regeneration capacity status. Four mangrove ecotypes were delineated namely seaward, middle, landward and riverine zones at each mangrove ecosystem, where dominant mangrove species were identified and selected for regeneration capacity study. Three subplots measuring 1 x 1 m2 were laid within the five 10 x 10 m2 survey plots established per zone. The juveniles were counted and categorized according to their height classes, using linear regeneration sampling method; where: RCI (≤40 cm) considered seedlings; RCII (41-150 cm) as saplings; and RCIII (151-≤300 cm) as small trees. Potential threats both anthropogenic and natural were determined through key informant interviews. Seven dominant species were identified across ecotypes in all mangrove sites, namely Avicennia marina, Avicennia rumphiana, Ceriops decandra, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, and Xylocarpus granatum. RCI (seedlings) is the most abundant across mangrove sites irrespective of the dominant species. Fishpond operation within the mangrove stand is considered a major threat to the juveniles and most mangrove ecosystems. Therefore, protection and constant monitoring of these mangrove ecosystems are necessary to ensure regeneration success in the future.
