DISTRIBUTION PATTERN OF LEPIDOPTERA (BUTTERFLIES) OF HAZARIBAG SANCTUARY, JHARKHANDJ.P. Sanyal
In the sanctuary insects have great role in the nutrient cycling and they play significant role in the niche of bird community. This paper deals with distribution pattern of Lepidopteran population. A comprehensive distribution pattern of butterflies has been studied. In the sanctuary area five study sites were selected considering habitat differences, present investigation was made only in the months of October 2002. Only ninteen species have been observed. Inter - specific association was calculated from two components (1) the statistical tests of significance (using a chisquare test statistic) and (2) indices Centroid Strategy index). the variance ratio test of schluter was used to assess the presence and absence of association. During the present investigation nine pairs of negative association. Negative interaction may be due to different resource requirement and positive interaction may be due to common response so a supply of unlimited reasons. Establishing the existence or absence of an association tells us nothing about the possible causes.
