Aluminium doped zinc oxide (Zn1-xAlxO) thin films were deposited by sol-gel spin coating technique onto a glass substrate (x=0-5wt%). The films were characterized by UV-Visible spectroscopy, SEM and were subjected to photoconductivity, temperature dependant conductivity and photo response measurements. The film with Al-1.5wt% showed the maximum absorption in UV and had a good optical transmission (~75%) in the visible regions respectively. The SEM images showed crack free films with little grain boundaries with decrease in grain size at higher aluminium concentration. The photoconductivity measurements reveal that there is a phenomenal increase in the photocurrent upon doping compared to undoped ZnO. The photocurrent reaches its maximum value (25μA) at 10V which is nearly 50 times more than the dark current (0.44μA) for Al-1.5wt% doped ZnO. The photocurrent then decreases for further increase in Al concentration. The photoresponse study gives the measure of rise and decay time. The rise time was found to be shorter for Al-1.5wt% among the doped film but longer than undoped ZnO. The temperature dependant conductivity shows that the thermal activation energy for the film decreases at Al-1.5wt% aluminium concentration and then increases for other concentrations in the temperature range 300-400K. The optimum conditions for maximum photoconductivity and photoresponse have been studied for photoconductive applications and the results presented.Keywords

Blackbuck are the only endemic antelope of India and occur patchily across the subcontinent. In Vallanadu they are confined to a small hillock over grown with dense thorny scrub which is not conducive for them. In this study we attempt to identify factors that would facilitate persistence of the species in the sanctuary and in the surrounding landscape. We did a spatial mapping of herbivores, carnivores, water resources, and presence of exotic plant species across two seasons. Blackbuck was largely found along the eastern boundary of the sanctuary and in the grassland habitats outside the reserve. No major predators of blackbuck were found but free ranging dogs were common and were noticed predating on smaller animals. Feral livestock outnumber all herbivores and are a major competitor with wild herbivores for forage and water in the sanctuary. There are no perennial water sources inside the sanctuary and Blackbuck depend on water available outside the reserve.Keywords

The Vallanadu Blackbuck Sanctuary (VBS), Tamil Nadu, India is a small protected area (PA) designated to conserve blackbuck. We did a study on habitat use and suitability in the PA that has come under various management interventions. The occupancy of blackbuck was positively correlated with areas lying within the PA, but the encounter rate of blackbuck was significantly higher in areas outside the PA. Being small in size, VBS may not hold a large population of blackbucks, but may help in saving the species which once widely occurred in the southernmost parts of India.Keywords

Despite decades of concerted global conservation efforts, biodiversity loss continues unabated, making it important to assess the effectiveness of conservation approaches. Using forest cover as a proxy for conservation effectiveness, we analysed land-use and land-cover changes across a community and a state forest of Jaintia Hills, Meghalaya, India. Forest losses in the community lands (77.94 sq. km) were higher compared to the state forest (11.48 sq. km) between 1994 and 2014, and were driven by mining, industry, plantations and agriculture. We examined the role of policies and institutional arrangements as larger drivers of forest change within the context of conservation effectiveness.Keywords

The Wayanad district of Kerala, India, is an important conservation and cultural landscape located in the Western Ghats biodiversity hotspot. It is a slightly east-sloping plateau with a unique geographical feature of small rolling hills interspersed with low-lying swamps and meandering streams. Extensive deforestation that occurred in the last century has severely fragmented and degraded the forest of Wayanad, leaving it as a mosaic of forests, wetlands, croplands and towns. The remaining forests in Wayanad are part of the Brahmagiri–Nilgiri–Eastern Ghats Elephant Landscape (NEG), which holds the single largest contiguous population of Asian elephants globally. The NEG is prone to seasonal fluctuation in resource availability, where a large tract of dry forest reduces its carrying capacity for elephants during summer. The Wayanad forests are a critical microhabitat for elephants in the NEG due to availability of fodder and perennial water sources during summer. Despite the importance of this region for elephants, the forest is ‘degrading’ drastically that will have a far-reaching impact on the long-term conservation of elephants in the NEG. Similarly, human–elephant conflict is on the rise and it is one of the biggest threats to the conservation of elephants and the well-being of rural communities in Wayanad. In this article we identify the current conservation issues and recommend future management of Asian elephants and their habitat in Wayanad.Keywords

Wintering ecology of many migrant bird species, especially migrant raptors is poorly studied. The semi-arid regions of southern Tamil Nadu (TN), India are a major wintering area and the southern limit for many migrant species. Historically there has been a loss of several grassland species from the area and currently, the natural grasslands are completely transformed. There are no studies on grassland birds in the region, especially on migrant harriers, which are grassland species and show a declining trend in most parts of the country. The present study is an effort to identify harrier roosts and record their numbers at the roost sites, during four winters from 2015 to 2019 in the districts of Tirunelveli and Thoothukudi in TN. Three species of harriers were recorded from 16 roost sites and roost counts at these sites varied from 75 to 2. The total number of harriers declined over the survey period and this was consistent across sites. Majority of the roosts were on private land and loss of roost sites to various land-use transformations is a major driver of harrier numbers in the area. Innovative approaches to protect and conserve grasslands are the need of the hour for the future of grassland species in the region.Keywords
