Tree Species Composition and Forest Stratification along the Gradients in the Dry Deciduous Forests of Godavari Valley, Telangana, India

It is important to understand the tree species composition, abundance, species diversity and stratification in tropical dry deciduous forests that are under threat. A quadrat study was attempted in the dry deciduous forests along the ecological gradients in the Godavari Valley of northern Telangana, India. The study records the presence of 110 flowering plant taxa belonging to 82 genera and 37 families in 120 sampled plots, and there was enumeration of 15,192 individuals of ≥10 cm girth at breast height. Tectona grandis (teak) is the principal forest cover component in the region, which often formed pure stands in Adilabad and, to some extent, in Nizamabad districts. Further down to the Warangal district, teak was gradually replaced by Terminalia alata. Twenty tree species were found dominant at one place to the other, and the top 10 dominant taxa have shared nearly 41% of the total density of the forest cover. The tree relative density ranged from 0.007% to 20.84%. The values of Importance Value Index were between 0.245 (12 spp. including some exotics) and 32.6 (teak). These baseline data help to know the change detection along the gradients in the tropical forest ecosystem of a major river valley in the region and the drivers of change

Ethnomedicine for dysentery and diarrhoea from Khammam district of Andhra Pradesh

443-447Dysentery and diarrhoea are common and age-old problems among the humans and cattle in the tropics. As a lead for new drug discovery, the ethnomedicine for dysentery and diarrhoea that is in practice among the tribes Konda Reddi, Koyas, etc. in Khammam district of Andhra Pradesh, is presented. Thirty seven plant species used for gastroenteric problems belonging to 28 families,representing 34 genera of Magnoliophyta have been reported. These include 34 dicots and 3 monocots; 28 native and 9 exotic species; 21 trees, 6 shrubs, 1 climber and 9 herbs; and 23 unknown and 14 known remedies

<i>In vitro </i>antimicrobial study of root extract of <i>Chlorophytum arundinaceum </i>Baker

503-506 The tubers of Chlorophytum arundinaceum Baker of Liliaceae family is a traditionally used medicinal plant with ethnic and/or folk claims like immunomodulatory, antidiabetic, anti-arthritic, aphrodisiac, etc. The in vitro antimicrobial activity of its root extract was evaluated against six bacterial species (Bacillus subtilis, Escherichia coli, Proteus vulgaris, Pseudomonas aeruginosa, Shigella sonnei and Staphylococcus aureus) and four fungal species (Aspergillus fumigatus, A. niger, Candida albicans and Trichophyton rubrum). The root extracts in solvents like petroleum ether/benzene, ethyl acetate, hydro-alcohol, methanol and chloroform showed moderate microbial activity whereas the aqueous root extract evinced no antimicrobial activity. None of the solvent extracts tested showed any activity against B. subtilis. The methanolic extract has shown maximum antibacterial as well as antifungal activity of the five solvent systems tried except A. fumigatus. </smarttagtype

Thermomucor abortosporangium sp. nov. (Fungi: Mucorales)

Thermomucor abortosporangium A. Swathi Sri & A. Subrahm., sp. nov. is described as the second species of Thermomucor. It differs from the type species of T. indicae-seudaticae in the branching pattern of sporangiophores, size and shape of sporangiospores and production of abortosporangia. Zygospores are reddish brown, globose, psilate, isogamic and formed at low (37°C) temperature whilst the higher temperatures are prohibitive. The fungus grows well at 50°C on PDA, SMA and MEA
