In order to achieve a good correlation between toxicology and Artemia salina lethality test, several chemical pollutants were examined in A. salina test with the purpose to use the latter as convenient preliminary protocol for toxic activity. During the test, the effect of a particular lethal dose or only a knockdown in the arthropod of HgCl2, KCN, K2Cr 2O7, C6H6 and C6H 6Cl6 was observed. The 24 h LC50 of these five chemical pollutants to A. salina was 0.12±0.09, 0.06±0.12, 0.72±0.21, 1.57±0.58 and 0.44±0.10 mg/L respectively. The results of the A. salina lethality test for the chemical substances are essentially in agreement with those described in literature for toxic activity. Although the A. salina assay is rather inadequate regarding the elucidation of the mechanism of action, it actually has proven to be a convenient system for monitoring the relative toxic potential of the chemical pollutants.

In present study, an efficient protocol was developed for induction of callus derived from corms of Gloriosa superba Linn. MS medium with various concentrations and combinations of growth regulators or other supplements was used. The best growth of callus was obtained in MS mediumcontaining 2.5mg/l BAP + 1mg/l IAA+.5mg/lKN+ 15%CW. © 2012 Trade Science Inc. - INDIA.

Background: The central Indian state Madhya Pradesh is often called as 'heart of India' and has always been an important region functioning as a trinexus belt for three major language families (Indo-European, Dravidian and Austroasiatic). There are less detailed genetic studies on the populations inhabited in this region. Therefore, this study is an attempt for extensive characterization of genetic ancestries of three tribal populations, namely; Bharia, Bhil and Sahariya, inhabiting this region using haploid and diploid DNA markers. Methodology/Principal Findings: Mitochondrial DNA analysis showed high diversity, including some of the older sublineages of M haplogroup and prominent R lineages in all the three tribes. Y-chromosomal biallelic markers revealed high frequency of Austroasiatic-specific M95-O2a haplogroup in Bharia and Sahariya, M82-H1a in Bhil and M17-R1a in Bhil and Sahariya. The results obtained by haploid as well as diploid genetic markers revealed strong genetic affinity of Bharia (a Dravidian speaking tribe) with the Austroasiatic (Munda) group. The gene flow from Austroasiatic group is further confirmed by their Y-STRs haplotype sharing analysis, where we determined their founder haplotype from the North Munda speaking tribe, while, autosomal analysis was largely in concordant with the haploid DNA results. Conclusions/Significance: Bhil exhibited largely Indo-European specific ancestry, while Sahariya and Bharia showed admixed genetic package of Indo-European and Austroasiatic populations. Hence, in a landscape like India, linguistic label doesn't unequivocally follow the genetic footprints. © 2012 Sharma et al.

Wetlands are one of the most productive ecosystems on this earth exhibiting a large diversity. The importance of wetlands are indicated by the Ramsar Convention. This study deals with the status of two wetlands i.e. Sasthamcottah Lake of Kollam, Kerala and Upper Lake of Bhopal, M.P. which are 'Ramsar Sites'. The paper helps in understanding the use of Remote Sensing and Geographic Information System (GIS) tools in mapping of surface water bodies and wetlands and also assessing the lake capacity. The major elements of this methodology involves the use of IRS LISS III sensors for delineating major geomorphological classes of wetlands. The change in the lake area was detected to be 82.67 Ha in the Sasthamcottah Lake and the capacity was deduced as 32,806.322 M.cu.m. Similarly the lake area change was 453.76 Ha in the Upper Lake of Bhopal with the current capacity to be around 79000.49 M.cu.m. © Research India Publications.

Bleachable grade of pulp is produced by sulphate chemical process because reduced pitch troubles with resinuous wood. The stream pollution and air pollution can be minimised by using anthraquinone. In sulphate pulping, the yield and properties of pulp produced are dependent on two sets of variables, with the fibrous raw material and with the pulping operation. The permagnate number and pulp yield are determined by analysis. On addition of anthraquinone in sulphate process, there is no adverse effect but it is helpful in reducing the cost of pulp.

The Rivers including river Yamuna and Ganges in upper reaches of Himalayan Mountains are yet some rivers and rivulets which are unpolluted and pristine. The analysis of physico-chemical Parameters of natural water of tributaries of River Beas in Palampur area of outer Himalayas was done by Following the Standard Methods for Examination of Water & Waste Water for analysis. Range of all the physico - chemical parameters was found within acceptable limits. As a result, water of all three tributaries viz. site I (Poon), Site II (Awa) & Site III (Mole) was found suitable for drinking purpose and will be helpful to solve the problem of drinking water in metropolitan cities. This can be supplied as drinking water after primary treatment at national level and opens up a new scope for starting a bottled water Industry by private organizations, thus will also help in providing employment to the local people of Tribal area where the scope of employment is very limited.

Preserving biodiversity means to protect small things even when we may never see them. This is the case with many of our inconspicuous, non-game fishes. They form the majority of our provincial fish diversity; so they are worthy of protection for this reason alone. However, they also perform a critical role in maintaining the health and well-being of our more "charismatic" fish species. The small but often abundant species are critical components of aquatic ecosystems and the fundamental building blocks of food webs that support the large, predatory game fishes. In "Lake City Bhopal" large number of lakes & reservoirs are present in and around the city; most of which are polluted due to multiple anthropogenic factors. Today it is well known fact that the environmental threats have caused damage to biodiversity including plants & animals. The environmental threats could be manmade, natural or in combination with cascading & interlinked impact and are responsible for decline in biodiversity present in these reservoirs. In the present paper, an attempt has been made to assess the water quality and fish diversity of two important wetlands of Bhopal; they are Motia pond and Jawahar bal udhyan pond from April 2010 to March 2011. The present paper deals with the study of water quality monitoring including important physical, chemical, biological parameters and fish fauna. On the basis of limnological parameters, it was observed that Motia pond is highly eutrophic wetland and only 9 fish species, 13 phytoplankton and 19 zooplankton genera were recorded and in Jawahar bal udhyan pond, which is also a eutrophic wetland, 13 fish species, 25 phytoplankton and 19 zooplanktonic genera have been recorded. On the basis of present study, it is seen that both wetlands are under great environmental stress and due to multiple anthropogenic factors specially joining of untreated raw sewage, water quality is deteriorated day by day and negative impacts on fish fauna have been observed.
