Ecologic study of soil oribatid mite, Scheloribates rectus (Acari) in high altitude Botanical Garden of Darjeeling Himalayas, India

Original Article


The results of some aspects of the ecology of Scheloribates rectus Hammer, 1958 in the soils of a high altitude Botanical Garden in Darjeeling Himalayas, India are presented. Soil samples were collected from two plots (‘X’ and ‘Y’) at monthly intervals for a period of three successive years (January 1999 to December 2001). Attempts have been made to determine the extent to which habitat complexity and local microclimatic variables influenced the population size of this mite. The total population of S. rectus exhibited an irregular trend of fluctuation during the period of investigation with a maximum in winter and minimum in monsoon months. There was a considerable post monsoon / winter increase in population size. Among the four edaphic variables (temperature, moisture, pH and organic matter), only the organic matter content exhibited a positive and significant correlation with the mite population, while the temperature, moisture and pH showed a significant but negative correlation. It was appealing to note that the studied plots being close to each other were more or less similar in edaphic and climatic conditions with a little variation in altitude and vegetation cover. However, the number of mite specimens varied from one plot to another. The reasons of seasonal abundance and numerical variation in the plots are discussed.
