Abstract

Animal monitoring is the key tool in the hands of park managers to effectively manage the forests and wildlife. Advances in the field of Wildlife science provide scope in this regard. Elusive Melanistic leopards or Black Panthers are more commonly found in the Dandeli-Anshi Tiger Reserve (Now renamed as Kali Tiger Reserve) as compared to other protected areas of Karnataka. Camera trap survey was conducted in the forest ranges of Kulgi, Phansoli, Gund and Anshi during January to June 2015. In this study an effort has been made to estimate the percentage of melanistic individuals in total leopard population. 94 pairs of Camera traps were placed covering 763 Km² area for 49 days in two blocks. Based on the image data the percentage of Melanistic animals in total leopard population has been derived.

Abstract

Here, the Double Exposure Holographic Interferometry (DEHI) technique is used to study the surface deformation on stainless steel substrate, when CdS is deposited on it. In the electrodeposition method at different concentrations, CdSO₄ is used as cadmium source, while Na₂S₂O₃ is used as a sulphur source and ethylene diamine tetra acetic acid (EDTA) is used as a complexing agent. The electro deposition of CdS thin films is carried out by varying the time of deposition. The deposition potential of the compound was studied by cyclic voltammetry. The structural, surface morphological and optical properties of the deposited films have been studied using X-ray diffraction (XRD), scanning electron microscope (SEM) and optical absorption technique respectively. The DEHI technique is used to determine, thickness of thin film and stress to substrate of electrodeposited CdS thin films for various deposition time and at various concentrations.
