Opis:: The aim of this study was to conduct the first comprehensive evaluation of carbon stock in the sediments of Avicennia marina (black mangrove) and Rhizophora mucronata (red mangrove) along the coastline of an arid region (Farasan Islands, Saudi Arabia). Such information is necessary for the development of any management plan for the mangrove ecosystems along the Saudi Red Sea islands and provide a rationale for the restoration of mangrove forests in Saudi Arabia. A. marina and R. mucronata locations showed significant (P < 0.001) differences in sediment bulk density (SBD) and sediment organic carbon (SOC) concentration with higher mean values for both in the sediments of A. marina. Considering the whole depth of sediment sampled (0–50 cm), the highest value of SOC stock (12.3 kg C m−2) was recorded at A. marina locations and the lowest (10.8 kg C m−2) at R. mucronata locations. Thus, the SOC stock of A. marina was greater than that of R. mucronata by 114.3%. Consequently, considering the rate of carbon sequestration and the area of mangrove forests (216.4 ha), the total carbon sequestration potential of mangroves in the Farasan Islands ranged between 10.3 Mg C yr−1 and 11.8 Mg C yr−1 for R. mucronata and A. marina locations, respectively. Thus, it is necessary to protect and restore these ecosystems for the sequestration of carbon and for their other valuable ecosystem services.

Opis:: The mangrove ecological services as carbon sinks and storage are very useful in the efforts to mitigate global warming and climate change. In this study, the above and below-ground biomass, carbon stock, as well as carbon sequestration by the mangroves in Demta Bay, Papua Province, Indonesia were estimated. Allometric equations were used to determine the mangrove biomass in 36 observation plots. The biomass value was used to determine carbon stock and estimate carbon sequestration. Nine mangrove species were found in Demta Bay, with the contribution of mangrove species to biomass (AGB and BGB) in the following order: Rhizophora apiculata > Rhizophora mucronata > Bruguiera gymnorhiza > Bruguiera cylindrica > Heritiera Littoralis > Xylocarpus molucensis > Rhizophora stylosa > Avicennia marina > Sonneratia caseolaris. The average mangrove biomass was estimated at 174.20 ± 68.14 t/ha (AGB = 117.62 ± 45.68 t/ha and BGB = 56.58 ± 22.49 t/ha). The carbon stocks in mangroves at the Ambora site were higher than the Tarfia and Yougapsa sites, averaging 123.57 ± 30.49 t C/ha, 81.64 ± 25.29 t C/ha, and 56.09 ± 39.03 t C/ha, respectively. The average carbon stock in the mangrove ecosystem of Demta Bay is estimated at 87.10 ± 34.07 t C/ha or equivalent to 319.37 ± 124.92 t CO2 e/ha. The results of this study indicate that the mangrove ecosystem in Demta Bay stores quite high carbon stocks, so it is necessary to maintain it with sustainable management. Therefore, climate change mitigation is not only done by reducing the carbon emission levels but also needs to be balanced by maintaining the mangrove ecosystem services as carbon sinks and sequestration.

Tytuł:: Phytopythium leanoi sp. nov. and Phytopythium dogmae sp. nov., Phytopythium species associated with mangrove leaf litter from the Philippines

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:: The heavy metal pollution in seawater and sediment can damage mangrove ecosystems and accumulate in mudskipper (Periophthalmus spp.) that lives in mangrove forests. The accumulation of heavy metal in mudskipper can affect the structure of its gill tissue, liver, and muscles. This research aims at (1) analyzing the levels of lead, cadmium and cuprum heavy metals in mudskipper, sediment, and seawater and (2) analyzing the damage to the gill, liver, and muscle tissue of mudskipper due to the exposure to heavy metals. The mudskipper samples were collected from the mangrove forests of Poka, Waai, and Rutong from May to June in 2019. The heavy metal analysis was conducted using the AAS method, while the gill, liver and muscle tissue staining was carried out with the HE (Hematoxylin Eosin) staining method with 40x magnification. The data were analyzed using descriptive analysis and correlational analysis. The results of the analysis showed that based on the mangrove locations, the order of Pb and Cu accumulation in mudskipper was Rutong> Poka> Waai; while the order of the Cd accumulation was Rutong> Waai> Poka. The changes in the gill tissue structure due to the exposure to heavy metals were in the form of teleangiectasia, secondary lamellar edema, hyperplasia, epithelial desquamation, clubbing, and primary lamellar edema. The changes in the liver tissue structure due to the exposure to heavy metals involved hemorrhage and fat degeneration. The changes in the muscle tissue structure due to the exposure to heavy metals include changes in muscle fibers, edema, and necrosis. The highest accumulation of Pb and Cd was found in gills and muscles from seawater, while low level of heavy metal Cu was found in the liver.
