ABSTRACT: Atmospheric concentration of sulphur oxides and nitrogen oxides suspended particulate matter (SPM) are on the rise, causing serious air pollution. Emission from stationary sources (fossil fuel combustion gases) and mobile sources (tail pipe) emissions contain pollutants such as SOx, NOx and particulate matter. SOx and NOx when inhaled causes respiratory disease. Very fine particulate matter is suspended in the air and hence called suspended particulate matter. It is considered to cause respiratory diseases and climatic changes. This article describes the role of monitoring of ambient air quality and pollutants emission sources in solving air pollution problems and effects of air pollution on animal health, primarily through monitoring activities.

ABSTRACT: Plant Secondary Metabolites (PSM) vary in their constituents and are known to perform diverse ecological functions notably in defence against herbivores, pathogens and abiotic stresses and in interactions with competitors and mutualists. Constitutive metabolites such as terpenoids, sulphur and nitrogen containing secondary metabolites can act as repellents, deterrents, growth inhibitors or poisons causing mortality in cases of antiherbivore function. However, other metabolites such as indole alkaloids and phenolics can be used by plants to choose adequate partners in order to alter the cost: benefit ratio of mutualism to their advantage. Also plants can /do adapt to extreme stress situations through their constitutive or induced metabolites such as; the UV-B protective function of flavonoids, pesticidal defense of coumarins, reactive oxygen species protection of isoflavonoids and other phenolic compounds. This review on the recent developments on this field provides a synthesis of the Function, Ecology and Evolution of plant secondary metabolites and also increasing the awareness of their integrative role in connecting natural systems. It emphasizes the multiple roles of secondary metabolites in mediating the interactions between plants and other organisms and with their environment at a range of scales of ecological organization.

ABSTRACT: A study was undertaken to explore the ornamental floristic wealth of the vast and verdant main campus of Banaras Hindu University, India, spreading over 1,300 acres of land area. A total of 390 ornamental plant species were recorded mostly dominated by the Angiosperms. The Angiospermic group of plants were represented by 231 genera and distributed among 71 families. The Fabaceae, Euphorbiaceae and Asparagaceae are the dominant families of the ornamental flora of Banaras Hindu University main campus. The exotic ornamental flora dominates over the native ornamental flora. The study also indicated the dominance of perennial ornamental plant species over the annual and biennial ornamental plant species.
