Abstract
The burrow density of sympatric murids in relation to various abiotic factors
viz· maximum and minimum atmospheric temperatures, relative humidity, soil temperature
and soil moisture was studied in the agro-ecosystem of village Kakrod-Jind (Haryana)
Analysis of monthly recorded data on burrow density revealed a biomodal pattern i. e. a
peak each during the months of September and March· Of these abiotic factors, soil
moisture revealed significant positive correlation with the burrow density whereas relative
humidity exhibited invariably the least interaction· However, path co-efficient analysis
depicted the direct effects of soil temperature and soil moisture and indirect effect of
maximum and minimum atmospheric temperature through soil temperature on the burrow
density· The use of path co-efficient analysis in such studies has been suggested·
