Hydrobiological parameters, population density and distribution pattern in the gastropod Nerita (dostia) crepidularia Lamarck, 1822, from mangroves of Vellar estuary, Southeast India
In the present study, the seasonal variation in physic-chemical parameters, population density and distribution pattern of Nerita crepidularia in the mangroves of Vellar estuary, Tamil Nadu was studied for a period of one year (January to December). The physico-chemical parameters such as temperature (atmospheric and water), pH, salinity, dissolved oxygen and rainfall were estimated. The atmospheric...

Role of auxin on adventitious root formation and subsequent growth of cutting raised plantlets of Ginkgo biloba L.
Role of some auxins, indol-3-butyric acid (IBA) and α-naphthalene acetic acid (NAA) has been examined for their stimulatory effects on adventitious root formation in stem cuttings of Ginkgo biloba as well as on subsequent growth and survival of these cutting raised plantlets. Lower concentration of IBA (10.0 µM) was found to be the most effective treatment as it not only...

Plant composition and growth of wild Coffea arabica: Implications for management and conservation of natural forest resources
The montane rainforests of Ethiopia are the only places of origin and genetic diversity for Coffea arabica species. These natural forest areas with the occurrence of wild coffee gene pools are however under constant threats, largely due to anthropogenic activities. The study aims to determine the variability in plant compositions and growth of wild Coffea arabica trees in the natural...
