Abstract

Nitrogen and phosphorus retranslocation efficiencies were measured in three evergreen tree species planted on mine spoil and the efficiencies were compared with same aged plants of same species planted on normal soil. The N and P retranslocation efficiencies were found greater in plants planted on mine spoil in all three tree species compared to those planted on soil. The two non-leguminous species Eucalyptus hybrid and Grevillea pteridifolia had shown a higher efficiency for N retranslocation and lower efficiency for P retranslocation, while contrary to this the only legume L. leucocephala had shown a higher efficiency for P retranslocation and a lower efficiency for N retranslocation.

Abstract

The effect of structural characteristics of mine spoil was studied on biomass production of two tropical herbaceous legumes Stylosanthes hamata and Stylosanthes humilis. The structural variation had marked influence on biomass production. The ischolar_main, shoot and total biomass production was greater at less rocky spoil site than more rocky spoil site in both the leguminous species. However, the ischolar_main/shoot ratio was greater at more rocky spoil site than less rocky spoil site in both the species.

Abstract

The impact of fertiliser amendment was studied on biomass production of grass Bothriochloa pertusa sown on a coal mine spoil. Two different doses of NPK fertiliser amendments were used along with control. The response to fertilisation was comparatively greater for shoot biomass than ischolar_main biomass. The shoot biomass, ischolar_main biomass and total biomass was significantly greater in fertilised plots compared to control plots. The ischolar_main/shoot ratio was significantly greater in control than fertiliser amended plots.

Abstract

Plantation of Dendrocalamus strictus was raised on coal mine spoil at Jayant project, NCL, Singrauli in June 1993. Half and full dose of NPK fertilizer was applied. Full dose of NPK fertilizer was nitrogen as urea (60 kg ha^-1), phosphorus as single superphosphate (30 kg ha^-1) and potash as muriate of potash (40 kg ha^-1). Half dose of NPK treatment increased the height growth more whereas full dose of NPK treatment enhanced markedly the number of culms/clump and diameter growth of D. strictus.

Abstract

The feasibility of direct seeding of tree species as a means of revegetating the flat (l.5 ha) and slopy areas (8 ha) of coal mine spoils was tested at Jayant Project, Northern Coal Fields Ltd., Singrauli. Direct seeding of tree species for 3-4 years with seeding of grasses and leguminous forbs is a potentially suitable technique for quick stabilization of flat and slopy areas of coal mine spoils. This technique is also beneficial in increasing the rate of recruitment of naturally colonizing plant species on mine spoils, which will ultimately restore the biodiversity and soil fertility of mine spoils, and will check the soil erosion from mine spoils.

Abstract

Pennisetum pedicellatum and Heteropogon contortus grasses were seeded in tree plantation plots on coal mine spoils at Jayant Project, NCL, Singrauli. After three year of raising of plantations the tree canopies affected the growth of seeded grasses. The dense canopy of D. strictus, P. pinnata and L. leucocephala completely eliminated the seeded grasses H. contortus and P. pedicellatum. Under the dense canopy for G. arborea only H. contortus grows well whereas P. pedicellatum was eliminated. Thus to increase the herbaceous plant biodiversity and for the establishment of stable plant communities thinning of plantation plots after 3-4 years is essential, and H. contortus should be preferred in ground seeding compared to P. pedicellatum.

Abstract

Phytoplankton are key components in primary production and their growth is determined mainly by the availability of nitrogen-nutrients in the ocean. The paradigm that phytoplankton prefer ammonium over nitrate when both substrates are present has been tested using ¹⁵N-labelled tracers on cultured diatoms and dinoflagellates isolated from two widespread geographical areas - the Baltic Sea and the Arabian Sea. We found contrary to the paradigm that both taxa preferred nitrate over ammonium and a significant within-species variation in N assimilation. Carbon uptake rates in the same experiments were estimated using ¹³C-labelled tracer.

Keywords

Abstract

MATLAB^TM is a powerful, easy to use, software package suitable for many mathematical operations, which finds plenty of scientific applications. One such application is the fitting of trend lines for a given data set so as to interpret the relationship of the variance of the parameters involved. We provide here a code in MATLAB^TM that performs the weighted linear regression with (correlated or uncorrelated) errors in bivariate data which can handle 'force-fit' regression as well.

Keywords

Weighted Linear Regression, Correlated Errors, Force Fit, Trend Line, Bivariate Regression.

Abstract

The first International Indian Ocean Expedition (IIOE; conducted in the early 1960s) was one of the greatest international, interdisciplinary oceanographic research efforts. It involved 46 research vessels (under 14 different flags) that carried out an unprecedented number of hydrographic surveys (and repeat surveys) of the entire Indian Ocean (IO) basin from 1960 to 1965. One key to the successful qualitative and quantitative assessment of plankton organisms across the IO was the unification of zooplankton collections using the IO Standard Net.
