Chittagong Hill Tracts (CHT) is situated in the Southeast of Bangladesh covering about 10 per cent of the total land. It is the native hoe of 13 tribal communities and these communities have their own traditional knowledge for natural resource managements. This paper provides 8 traditional knowledge namely, folk classification of landform, land use zoning, community reserve for common resource ...

India’s forest cover was estimated to be about 67.701 million hectares or 22.8 percent of the country’s land area and other wooded lands comprise of 4.11 million ha (UNEP Report, 2000). The dense forests in almost all the major states has been reduced and forest degradation is a matter of serious concern now. Principal plantation species such as Acacia spp., Eucalyptus spp. and Tectona grandis ...

The short-term effect of prolactin on the skin of the adult tree frog Hyla arborea japonica was investigated using current-fluctuation analysis. Basolateral application of ovine prolactin (10 microg ml(-1)) (1) increased the amiloride-blockable short-circuit current (SCC) across the skin 2.6+/-0.4-fold and (2) increased the open-channel density (M) of the epithelial Na(+) channel 6.1+/-1.2-fold...

Lignin, an amorphous biopolymer is one of the major components wood. In this study, lignin was extracted from Gmelina arborea wood using Soda and Kraft pulping processes. The characterized Fourier Transformed Infrared Spectrometer (FTIR), UV/visible spectrometer, electrospray ionization mass spectrometer scanning electron microscope (SEM). Results revealed that G. lignins contained several chem...

We report a case of anisocoria in a 6-year old child who felt out of an inflatable swimming pool in the garden. After instillation of pilocarpine 1% the dilated pupil constricted, which is an important clinical sign associated with intracranial trauma. There was evidence of exposure to angel's trumpet (Brugmansia arborea), a plant known to contain anticholinergic substances. As the results of f...

We investigated sex-specific recombination rates in Hyla arborea, a species with nascent sex chromosomes and male heterogamety. Twenty microsatellites were clustered into six linkage groups, all showing suppressed or very low recombination in males. Seven markers were sex linked, none of them showing any sign of recombination in males (r=0.00 versus 0.43 on average in females). This opposes cla...
