Impact of mining on tree diversity of the silica mining forest area at Shankargarh, Allahabad, India

Journal of Forestry Research 2011年第4期22卷 527-532页

作者： Kumud dubey K. p. dubey Centre for Social Forestry and Eco-Rehabilitation 3/1 Lajpat Rai Road Allahabad-211002 U.P. India. Conservator of Forest O/O Chief Conservator of Forest (Southern Zone) Office Allahabad-211001. U.P. India.

The Shankargarh forest area is rich in silica, a major mineral used in glass industry. Extensive open cast silica mining has severely damaged the forest as well as productivity of the region. An understand- ing of the impact of mining on the environment particularly on vegetation characteristics is a prerequisite for further management of these mining sites, especially in the selection of species for reclamation works. The present paper deals with the study of the tree composition of silica mining area of Shgankargarh forest, at both disturbed and undisturbed sites. Tree vegetation study was conducted at undisturbed and disturbed sites of Shankargarh forests using standard quadrate method. Density, abundance and frequency values of tree species were calculated. Species were categorized into different classes according to their frequency. The importance value index （IVI） for each species was determined. Species diversity, Concentration of dominance, Species richness and Evenness index were calculated for the undisturbed and disturbed siteS. The distribution pattern of the species was studied by using Whifford＇s index. Similarity index between tree composition of disturbed and undisturbed sites was determined by using Jaccard＇s and Sorenson＇s index of similar- ity. Tree species showed a drastic reduction in their numbers in disturbed sites compared to that of the undisturbed sites. The phytosociological indices also illustrated the impact of mining on the tree composition of the area. The present study led to the conclusion that resultant tree vegetation analysis can be used as important tool for predicting the suitability of particular species for revegetating the mined areas.

Neosporosis: An Overview of Its Molecular Epidemiology and pathogenesis

引用

Engineering 2020年第1期6卷 10-19页

作者： Asis Khan Jahangheer S.Shaik patricia Sikorski Jitender p.dubey Michael E.Grigg Molecular parasitology Section Laboratory of Parasitic DiseasesNational Institute of Allergy and Infectious DiseasesNational Institutes of HealthBethesdaMD 20892USA Animal parasitic Disease Laboratory Beltsville Agricultural Research CenterAgricultural Research ServiceUS Department of AgricultureBeltsvilleMD 20705USA

Neospora caninum (N. caninum), a cyst-forming protozoan parasite, is a major cause of bovine abortions and neonatal mortality worldwide. N. caninum has a broad intermediate host range, and its sexual cycle occurs exclusively in canids. Another species of Neospora, Neospora hughesi (N. hughesi), has been identified and causes myeloencephalitis in horses. Although molecular epidemiology studies are in their infancy, the 18S ribosomal RNA (rRNA) and ITS1 regions within the small subunit ribosomal RNA (ssuRNA) and an N. caninum species-specific DNA probe (pNc5) have been used extensively to differentiate Neospora from other closely related apicomplexan parasites. While these repetitive regions have higher sensitivity and specificity than housekeeping or antigen genes, they suffer from low discriminatory power and fail to capture intra-species diversity. Similarly, although multiple minisatellite or microsatellite marker studies have shown clear geographic substructures within Neospora, strains are often misclassified due to a convergence in the size of different alleles at microsatellite loci, known as homoplasy. Only one strain, N. caninum Liverpool (Nc-Liv), has been genome sequenced and compared with its closest relative, Toxoplasma gondii (T. gondii). Hence, detailed population genomics studies based on whole-genome sequences from multiple strains worldwide are needed in order to better understand the current population genetic structure of Neospora, and ultimately to determine more effective vaccine candidates against bovine neosporosis. The aim of this review is to outline our current understanding of the molecular epidemiology and genomics of Neospora in juxtaposition with the closely related apicomplexan parasites Hammondia hammondi and T. gondii.

Journal of Geographical Sciences 1997年第4期7卷 87-94页

作者： Dr. O. p. dubey "Guru" Department of Geography Dr. H. S. Gour Vishwavidyalaya Sagar 470003 (M. p.), INDIA

In the present study an attempt has been made to present a systematic and interpretative analyses of per capita foodstuffs consumption and nutritional level in the rural areas of Sagar division (M. p.). The Central thrust of this study has a bearing on the important aspect partaning to the vital relationship between food intake and health, following Gopalan et. al. (1993), per day per capita foodstuffs consumption is converted into their respective nutritive values. Our survey has revealed that the existing food habits in the villages under study lead to an imbalance of food intake, both quantity-wise and quality-wise, resulting to the nutritional deficiency is closely associated with the food production, diet habits and purchasing power of the individuals.

山羊住肉孢子虫的感染与免疫试验

动物医学进展 1986年第2期 36-40页

作者： dubey.J.p. 翁玉麟

狗能传播住肉孢子虫,并引起牛、绵羊、猪、山羊及骡鹿等产生急性致死性住肉孢子虫病(Fayerand Johoson,1973;Manday ef al.,1975;Roller ef al.,1977;Erber et a.,1978;Fischer,1979;dubey et al.,1981,1982),在山羊是否引起急性住肉孢子虫病与接种剂量有关,用低剂量接种的结果,产生无临床症状的感染,若接种100000个或更多的孢子囊就产生临床症状。在山羊能产生持久的免疫力以抵抗重新感染的文献报告只有一篇(dubey,1981),在这篇文献中山羊接种1000个孢子囊后无症状产生,于二个月后攻毒具有保护力。本文继续研究山羊住肉孢子虫病获得持久免疫保护力的试验。
