Avicennia marina (Forsk.) Vierh has a typical diurnal pattern of salt gland activity, with high secretion rate during the day, a peak at noon, declining after sunset, and remaining low throughout the night. The main factor affecting the daily secretion rhythm was radiation, with a 2-hr time lag between the radiation level and the corresponding secretion. This lag might be a result of a salt acc...

Mangrove leaves contain abundant bioactive compounds that can optimize the growth of shrimp. This research examined effect adding Avicennia marina to feed on and FCR Whiteleg shrimp determined optimal dose. seeds PL-20 were used in experiments employed RAL method with 4 treatments 3 replications. Different doses leaf extract used: (A) 125 ppm/500 g feed, (B) 175 (C) 225 (D). The amounted 3% tot...

Mangroves play an important role in carbon sequestration. However, mangroves can be sources of greenhouse gas (GHG) emissions. In this study, methane (CH4) emissions and related soil properties were determined multiple Taiwan, including Kandelia obovata Avicennia marina mangroves. K. possess prop roots, whereas pneumatophores are found A. marina. Our results showed that mangrove soils significa...

It is necessary to monitor and identify mangroves types and spatial extent near coastal areas because it plays an important role in coastal ecosystem and environmental protection. This research aims at identifying and mapping mangroves types along Karachi coast ranging from 24.79 to 24.85 in latitude and 66.91 to 66.97 in longitude using hyperspectral remote sensing data and techniques. Image a...

avicennia marina (avicenniaceae) is a species of mangrove tree used for treatment of small pox lesions in persian folk medicine. the antiviral activity of methanol, ethanol, water, chloroform and n-hexane extracts was evaluated against hiv-1 and hsv. methanol extract had the highest antiviral activity and the most polar fraction of this extract (fraction d) inhibited hsv with ti and si values o...

The part of central west coast (Maharashtra and Goa) of India has been classified and quantified for coastal wetlands using LANDSAT data of 1985-86. The classification accuracy of the maps and area estimates achieved was 84% at 90% confidence level and the planimetric accuracy at 1:2.50.000 scale was 0.3 mm. The total coastal wetland areas in Maharashtra and Goa. have been estimated to be 1567 ...

This paper attempts to integrate satellite imagery such as Cartosat-1 with high spatial resolution and IRS P6 LISS IV with high spectral resolution using digital image fusion algorithms. This integration and mixing of hispectral and higher spatial data with complementary spectral and spatial characteristics, has proved to be promising to obtain images with high spatial and spectral resolution s...

Endophytic Sporosarcina aquimarina SjAM16103 was isolated from the inner tissues of pneumatophores of mangrove plant Avicennia marina along with Bacillus sp. and Enterobacter sp. Endophytic S. aquimarina SjAM16103 was Gram variable, and motile bacterium measured 0.6-0.9 μm wide by 1.7-2.0 μm long and light orange-brown coloured in 3-day cultures on tryptone broth at 26°C. Nucleotide sequence of...
