    Opis:
    The mangrove adaptations in the environment are the majority essential for the sustainable survival, development and intertidal zones due to special ability of salt tolerance. Mangroves possess a general characteristic to tolerating high salinity of seawater. Notably, they normalize ion homeostasis below brackish stress by salt secretion also ultrafiltration and ion appropriation. The plants have development of complex, physiological and anatomical adaptations allowing survival in their high stress habitat. The mangrove should restrain with aeration effect of sun, storm, osmotic disproportion, high salinity, brackish oxygen lacking and water- logged soils. Although, the reaction of adaptations the majority obvious attribute be succulent vegetation with increase mesophyll area, broad cuticle and wax deposition on the epidermis. The anatomical distinctiveness are the foundation designed for their physiological alteration to soaring salt condition.

    Opis:
    A survey on the cyanobacterial biodiversity of 7 mangrove environments viz. Vallikunnu, Kadalundi, Kallayi, Mangalavanam, Kumbalam, Kumarakom and Mekkara mangroves of Kerala was undertaken during 2014-2016. In total, 31 species of cyanobacteria coming under 10 genera and 4 families were recorded in all mangrove environments. Maximum species (13 species) of cyanobacteria were recorded from Kadalundi, whereas the minimum was recorded from Mangalavanam (2 species). The genus Oscillatoria was observed with maximum distribution (13 species), followed by Nostoc (5 species) and Lyngbya (3 species). The genus Aphanocapsa, Microcoleus and Scytonema (2 species each) and Chroococcus, Aphanothece, Merismopedia, and Phormidium (1 species each) shows equal distribution. As many as three species, namely Oscillatoria salina, Oscillatoria ornata and Oscillatoria vizagapatensis were common in all mangrove environments except Mangalavanam and Mekkara.

    Opis:
    The genus Phytopythium is a monophyletic taxon of the Peronosporaceae with characteristics intermediate between Phytophthora and Pythium. In the Philippines, reports of Phytopythium are scarce, with the mangrove-swamp-inhabiting species Phytopythium kandeliae being the only species recorded to date. It was the aim of the current study to investigate the diversity of Phytopythium in mangrove habitats in more detail. Based on culture characteristics, morphology, and molecular phylogenetic position, two new species of Phytopythium are described from Philippine mangroves, P. leanoi USTCMS 4102 and P. dogmae USTCMS 4101. Phytopythium leanoi is a species morphologically similar to P. kandeliae, but with the ability to develop gametangia in a homothallic fashion. The other new species, P. dogmae, is characterized by having a short discharge tube, semipapillate to papillate sporangia and frequently exhibiting a clustering of two sporangia per sporangiogenic hypha. With the addition of the two species described in this study, the genus Phytopythium has grown from around 10 to beyond 20 recognized species over the past decade, and it seems likely that several more species of this genus await discovery.

    Opis:
    Background. Mangrove forests have long been known as a source of phytochemical compounds producing various secondary metabolites. Despite the ubiquitous diversity of polyisoprenoids in the plant kingdom, few studies have focused on the distribution of polyisoprenoids in mangrove plants. The present study describes the distribution and occurrence of a new class of prenyl derivates – polyprenyl acetone as well as other polyisoprenoids in fourteen species of Indonesian mangroves, with an emphasis on chemotaxonomic importance. Material and methods. The leaves and roots of fourteen North Sumatran mangroves were analyzed using two-dimensional thin layer chromatography and electrospray ionization mass spectrometry. Results. In the leaves, the distribution of several types of polyprenyl acetones, polyprenols, and dolichols was detected and classified into types: type-I, having a predominance of dolichols over polyprenols (more than nine-fold), was observed in Acrostichum aureum (younger leaves), Avicennia alba, Av. lanata, Av. officinalis, Bruguiera parviflora, Ceriops tagal, Nypa fruticans, and Rhizophora mucronata; type-II, having the presence of both polyprenols and dolichols, was observed in Acanthus ilicifolius, Acr. aureum, B. cylindrica, and R. apiculata; type-III having a predominance of polyprenols over dolichols (more than nine-fold), was not observed in any North Sumatran mangroves; type-IV, having the presence of both polyprenyl acetones and dolichols, was observed in Aegiceras corniculatum; type-V, having the presence of polyprenyl acetones, polyprenols, and dolichols, was observed in Sonneratia caseolaris and Xylocarpus granatum. In the roots, type-I distribution was observed in Ae. corniculatum, Av. alba, Av. lanata, Av. officinalis, B. parviflora, C. tagal, N. fruticans, R. apiculata, R. mucronata, S. caseolaris, and X. granatum. Type-II distribution was observed in Ac. ilicifolius, Acr. aureum, and B. cylindrica. Type-III, -IV, and -V distributions were not observed in mangrove roots. Cluster analysis demonstrated that polyisoprenoid patterns in the leaves and roots form distinct separation into appropriate genera and tribe, suggesting that mangrove polyisoprenoids are chemotaxonomically significant. Conclusions. The major polyisoprenoid alcohols in Indonesian mangroves were found to be dolichols rather than polyprenols. The diversity of polyisoprenoids in both leaves and roots of mangroves may provide chemotaxonomic marker. The discovery of a new class of polyprenyl acetone is the first report from mangrove plants.

    Opis:
    Mangroves and the associated shoal forest known as ‘restinga' are ecosystems of great ecological relevance that play a significant role in the protection of the coastline in tropical regions. In Brazil, the coastal region has been severely affected by urban expansion. The Paranaguá Port, located in Paraná State (Brazil), is the fourth most important Brazilian port in throughput, and is located in an estuarine region which features large mangrove forests. An historical assessment of its inner access channel dredging rates was made to assess the impacts that the expansion of the Port in the last 30 years may have caused to the ecosystem. In the following, the historical data concerning the dredged volume in the inner access channel was compared to the mangrove and the shoal forest associated variation, aiming to establish a potential correlation between vegetation and siltation in the inner access channel to show as the preservation or restoration of specific ecosystems has potential to Nature-Based Solutions.

    Opis:
    This research was conducted on November 2018 - January 2019. The method used was the survey method by making direct observations on the stations that have been determined. The results of the research include two types of mangroves found, they are Rhizophora stylosa and Aviciena marina. The highest mangrove density was found at station 1, as many as 2302 ind / ha which dominated by R. stylosa. Gastropods found were Casidulla aurisfelis, Cerithidea sp., C. cingulate, C. alata, C. obtusa, Polinices sp., Puperita sp., Tarebia sp., Telescopium telescopium, and Turricula flammea. The Diversity Index obtained is 0.998 - 2.547, indicating moderate diversity. The uniformity index obtained is 0.10 - 0.27, indicating that there was a dominant community. While the relation between mangrove vegetation density and gastropods was 0.95, this shows that there is a very strong relation between the density of mangroves and gastropods.
