The southern Gulf of Mexico (sGoM) is highly susceptible to receiving environmental impacts due to the recent increase in oil-related activities. In this study, we assessed the changes in the bacterioplankton community structure caused by a simulated oil spill at mesocosms scale. The 16S rRNA gene sequencing analysis indicated that the initial bacterial community was mainly represented by Gamma-proteobacteria, Alpha-proteobacteria, Flavobacteriia, and Cyanobacteria. The hydrocarbon degradation activity, measured as the number of culturable hydrocarbonoclastic bacteria (CHB) and by the copy number of the alkB gene, was relatively low at the beginning of the experiment. However, after four days, the hydrocarbonoclastic activity reached its maximum values and was accompanied by increases in the relative abundance of the well-known hydrocarbonoclastic Alteromonas. At the end of the experiment, the diversity was restored to similar values as those observed in the initial time, although the community structure and composition were clearly different, where Marivita, Pseudohongiella, and Oleibacter were detected to have differential abundances on days eight–14. These changes were related with total nitrogen (p value = 0.030 and r2 = 0.22) and polycyclic aromatic hydrocarbons (p value = 0.048 and r2 = 0.25), according to PERMANOVA. The results of this study contribute to the understanding of the potential response of the bacterioplankton from sGoM to crude oil spills.

Abstract. Dutta S, Hossain MK. 2020. Bringing back the Chakaria Sundarbans mangrove forest of South-east Bangladesh through sustainable management approach. Asian J For 4: 65-75. The oldest mangrove forest of Indian sub-continent namely Chakaria Sundarbans (CS) is currently in a critical situation. Destructive anthropogenic and natural impacts coupled with shrimp farming and excessive grazing has caused severe damage to this oldest mangrove ecosystem. A study was carried out based on the extensive literature survey and tried to explore the overall situation and conservation practices for CS of Bangladesh. This paper analyzed, reviewed, and identified the impacts of natural and man-made effects on CS mangroves. Finally, we recommended the sustainable management approach (SMA) including policy and participation of the local people for bringing back this potential natural mangrove forest resource of CS along with rich forest diversity.

Makrobenthos that live in the mangrove forest can be used to predict the role or contribution of mangrove ecosystems as a source of natural food for the environment. The aims of research to determine the structure, composition, abundance, diversity makrobenthos of the mangrove ecosystem. The study was conducted by comparing the community structure makrobenthos in pond ecosystem with mangrove vegetation constituent . The location of this study include three areas , Mangunharjo (Semarang), Surodadi (Demak) and  Pasarbangi (Rembang). The result can shows makrobentos species composition is dominated by gastropods ( 18 species) , Bivalvia ( 13 species ) , Polychaeta ( 3 types ) , and crustaceans ( 2 types ) . Cerithium and Littorina scabra is a type that has a high density of the mangrove ecosystem . There are differences in the abundance and diversity of plankton and makrobenthos at three study sites. In general Pasarbangi Coast has the highest abundance and diversity . Macrozoobenthos community structure in mangrove ecosystems that exist in the three study sites in a stable state , species diversity and distribution of the number of individuals of each type of uniform . Pasarbangi area with mangrove vegetation polyculture farms , have high primary productivity . This shows the level of primer productivity at the site is also high . Keywords: community structure, macrobenthos, pond ecosystem
