The role of bamboo (Dendrocalamus strictus) in causing spatial patterns in ecosystem structure and function has been studied in East Mirzapur Forest Division. The Bamboo savanna is characterized by spatial heterogeneity in form of concentric zones around the bamboo clumps showing greater productivity and soil fertility. The bamboo influence zone (about 1.25 m around the clump), having considerable input of bamboo litter and fine ischolar_mains, is characterized by greater accumulation of organic carbon and nutrients relative to the intervening herb covered zone. Compared to the herb zone, the increase in 0-30 cm soil content in the bamboo zone ranged: organic carbon 15-17 per cent, total nitrogen 7-11 per cent, available phosphorus 25-29 per cent, exchangeable potassium 20- 35 per cent. Because only <20% of the land area is strongly modified by bamboo with respect to soil fertility, it is suggested that a reduction in clump spacing may enhance the productivity of bamboo through its greater regulation of the nutrient relations as well as higher clump densities in the bamboo savanna ecosystem. The presently used clump density, therefore, needs a reappraisal.

Changes in ecosystems are highly complex, heterogeneous and are extremely difficult to measure through single scale. Fractal geometry has been used to quantitatively estimate the extent of irregularity in ecosystem changes. However, in some cases it has been overly used giving misleading results. To avoid this, other metrics are also being used in studying changes in forest ecosystems. In this article, we review use of fractal geometry in measuring ecosystem components in a range of ecological conditions. Further, case studies from forest fragmentation and soil aggregates stability in different Indian tropical ecosystems with respect to management practices and environmental change have been described using fractal dimension. We have tried to point out some instances where fractals can more appropriately be used in assessing ecosystems properties and where it could not be successfully used. Characterization of ecological situations where fractals can effectively be used in general remains an important issue.Keywords

Nutritional problems among children are common in India and one of the reasons is poor feeding practices among the young children. The best way of ensuring child survival is to initiate steps to improve nutritional status of children. Nutrition and hearth of child is the product of dietary intake and morbidities suffered by the child. Several studies have demonstrated that during major diseases viz., diarrhoea and acute respiratory infection, feeding practices are jeopardized.- Gregarious Flowering of a Geriatric Semelparous Bamboo – Bambusa tulda Roxb. in Mizoram, India
