The north eastern part of Anantapur district is in the state of Andhra Pradesh, India, is significant as it is covered by varied geological formations and has different land use and irrigation practices. Though ground water is the major drinking water source, deterioration in its quality is going unchecked. In such agro-economy based rural areas, the nitrate contamination is rampant and much atten ...
... Intercropping system of cereals with legume is common in semi-arid tropics of India. However, little attention has been paid to assessing nutrient competition in the system. Seasonal changes in relative dry matter yield (RDY), relative nitrogen yield (RNY), relative phosphorus yield (RPY) and relative potassium yield (RKY) are useful indices to estimate the N, P and K status in intercropping syste ...
... We assessed the potential of fluoride (F) contamination in drinking groundwater of an intensively cultivated district in India as a function of its lithology and agricultural activities. Three hundred and eight groundwater samples were collected at different depths from various types of wells and analyzed for pH, EC, NO₃-N load and F content. A typical litholog was constructed and database on fert ...

Abstract:
... The seasonal effects of untreated and treated municipal sewage on the nutrients--nitrate (NO₃), phosphate (PO₄), sulphate (SO₄), and the biochemical oxygen demand (BOD), chemical oxygen demand (COD) and dissolved oxygen (DO) of the receiving urban canal, the Buckingham canal at Kalpakkam (Tamil Nadu, India) was monitored monthly during pre- monsoon--2005 to post-monsoon--2006. The NO₃, PO₄ and SO₄ ...

Abstract:
... To develop total DNA extraction protocol from saline soil for further metagenomic applications. The protocols combine the application of mechanical (Beads and Sonicator) and Soft Lysis (SDS and enzymes) method for the isolation of total DNA from saline soil of coastal Gujarat followed by its quantification and purity assessment. The quality and purity of metagenomic DNA was quite consistent and re ...
... Increased consciousness about agricultural sustainability and health risks associated with agrochemicals has lead organic farming to be a globally emerging alternative farm practice. We report the effect of atmospheric deposition on soil quality and heavy metal contamination of agricultural produce under an organic farming system using wheat and corn as test crops. Data obtained in the open field ...
... To assess levels and seasonal trends of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in a high-altitude mountain region, a 2.1m snowpack sample was collected from the East Rongbuk Glacier at 6572ma.s.l. on Mt. Everest in September 2005. This snowpack covered a full year period from the fall of 2004 to the summer of 2005 and reflected the major meteorology of the monsoon an ...

Abstract:
... Understanding local attitudes towards human-wildlife conflict (HWC) is key to developing successful conflict mitigation strategies. In this paper, in-depth interview and questionnaire data about resolution of HWC in Uttarakhand, India are examined from both qualitative and quantitative approaches (n = 70). Responses are differentiated between and within three subgroups: gender, literacy status, an ...

Abstract:
... The major objective of the investigation was to evaluate the road traffic noise and its likely impacts on the local community of Asansol city (West Bengal, India) by monitoring and modeling. The attitudinal response of local population due to existing vehicular noise is presented in the paper. Noise and Attitudinal Survey was conducted at 25 locations. A total of 869 individuals were surveyed. The ...
... Spruceanthus thozetianus , known to be distributed only in Australia so far, is recorded here for India from the southern Western Ghats. A detailed description with information on capsule and spores for the first time is provided here with an illustration and a distribution map. ...
Mimetidae; fauna; invertebrates; new species; phylogeny; predators; webs; Australia; India; New Zealand
Abstract:
... Pirate spiders (Mimetidae) are well known for their specialised feeding ecology. They are vagrant araneophagic predators, enter the webs of their prey spiders and exhibit patterns of aggressive mimicry to overcome the web owner. The mimetid fauna of Australia and New Zealand currently consists of 26 species in the following three genera: Australomimetus Heimer, 1986 (18 species), Mimetus Hentz, 18 ...

Abstract:
... Mutations in the BRCA1 and BRCA2 genes profoundly increase the risk of developing breast and/or ovarian cancer among women. To explore the contribution of BRCA1 and BRCA2 mutations in the development of hereditary breast cancer among Indian women, we carried out mutation analysis of the BRCA1 and BRCA2 genes in 61 breast or ovarian cancer patients from south India with a positive family history of ...
