Opis:
Arenicola marina (Linnaeus, 1758), a marine polychaete worm of the phylum Annelida is rarely seen but its coiled castings are a familiar sight on a beach at low tide of both northern and southern hemisphere. The genus Arenicola enjoys a wide distribution and in the tropical and sub-tropical regions A. cristata is the dominant species. Apart from a few records on the beaches of Indian Ocean and Arabian Sea the genus has not been known so far from any other part of India. In a study on the sandy as well as mudflats of Bay of Bengal at Chandipur in Odisha, India, we observed quite a big numbers of castings of Arenicola during the end of December, 2015 and accidentally found a full grown individual at the sandy beach. From that point of view it is the first report of its kind from this part of the globe, especially from Bay of Bengal, India.

Opis:
The current study was intended to evaluate abortifacient and antioxidant activity of Avicennia marina leaves extracts. Abortifacient activity was evaluated in rats, compared with standard drug (Mifepristone) and antioxidant activity was evaluated by using three free radicals (Superoxide, Hydroxyl and DPPH) compared with Ascorbic acid. The extracts were showed pre implantation loss, post implantation loss of implantations and decreased the survival ration of foetuses. Among all extracts hydroalcoholic extract showed better activity. The selected plant extracts showed concentration dependent percentage inhibition of free radicals. Among three extracts hydroalcoholic extract showed better activity with IC50 values on superoxide, hydroxyl and DPPH radicals were 203μg, 237μg and 143μg. From the results obtained during the study it the hydroalcoholic extract was used for the isolation of pure compounds, and isolated the different compounds (β-sitosterol, Lupeol and Betulinic acid).

Opis:
This study aims to determine what is the influence of the density of mangroves on the rate of coastal sediment transport and abrasion that occurred in the Sikakap Coastal area of Mentawai Island district. The research method used is the quadratic transect method and the sediment trap method. The type of mangrove vegetation that dominates in the Sikakap Coastal area of Mentawai Island district is Avicennia marina. Tree level mangrove density at Station I is 1,450 stands / ha and categorized as good, while the tree level mangrove density at Station II is 900 stands / ha and categorized as heavily damaged mangrove forests. The relationship between mangrove density and transport sediment rate in Sikakap Coastal, Mentawai Island district shows a negative correlation with the value -1, meaning that when mangrove density is high, the transport sediment rate will be low, and vice versa, when mangrove density is low, the transport sediment rate will be high.
