Abstract
The study reports the diversity and seasonal population dynamics of earthworms at Srinagar based on the data collected from four sites. A total of five earthworm species- Aporrectodea caliginosa trapezoides, Aporrectodea rosea rosea, Eisenia fetida, Octolasion cyaneum and Drawida japonica were recorded. Out of the five species, A. c. trapezoides was present at maximum sites whereas D. japonica and O. cyaneum exhibited restricted distribution. Diversity indices- Margalef species richness and Shannon-Wiener diversity index exhibited maximuim value of 0.31 and 1.05 at site-III respectively. pH and EC exhibited significant variation within the sites (F3= 40.28; 46.94 P < 0.05), temperature among the seasons (F3=137.91, P < 0.05) whereas moisture and organic carbon among the seasons (F3= 7.10; 3.88, P < 0.05) and within the sites (F3= 30.55; 57.09, P < 0.05). pH, organic carbon, organic nitrogen along with moisture favors the diversity of earthworms whereas the temperature affects the overall population dynamics.
