Ownership structure of protected areas influences the patterns of seed removal by mammals

  In Mexico, nature reserves vary greatly in the size of the property, administration, financial budget and measures to protect against land use change and illegal hunting. We compared two private and two public reserves and observed an influence between the ownership structure and the patterns of removal of large and small seeds from the forest floor by medium-sized mammals and rodents. We hypothesized that...

A survey of habitat invetorization and habitat potentiality for sustenance of Gharial in Sone (Gavialis gangeticus) Gharial Sanctuary

  The present study was carried out to find out the diversity of Gharial and potential habitat for its survival. A total of 161 km area in the Sanctuary was studied and data related with population of Gharial, habitat features, river profile, human activities and threats were collected. The Sone River apparently supports a few viable populations of Gharial. The population of Gharial shows 40% reduction...

The influence of sterilizing compounds on the yield of viable explants of Rhododendron L. (Ericaceae)

  Results are presented on the influence of sterilizing compounds upon the yield of viable explants of Rhododendron in sterilized culture. Yield of viable explants is dependent upon type of sterilizing compound, the type of specie the plant belongs and the type of explant. Results show,  that 0.1% solution of silver nitrate is the most effective compound for sterilization of seeds of...
