Studies on the effects of some physico-chemical parameters on the distribution of Collembola: A case study from Hooghly District, West Bengal
Keywords:Abundance, Seasonality, Soil Moisture, Springtails
The study reflects the distribution pattern of collembolan fauna in four study sites of Hooghly district on fluctuation of soil parameters such as moisture, temperature, and pH. Seasonal impact on species number and composition has also been observed here. The ecological study of the Collembola about some physico-chemical parameters has not been studied so far in the district of Hooghly, West Bengal. The seasonal abundance of the Collembolan population depends on soil moisture, neutral pH and humic soil. We have encountered a total of 25 species under 17 genera from 13 subfamilies of 9 families under 3 orders. The analysis represents that the family Entomobryidae is the most dominant one (32%) followed by Paronellidae (20%) and Isotomidae (12%). The members of the genus Lepidocyrtus Bourlet, 1839 are abundant (46.69%) and species-rich. There is a spike in the number of individuals during the spring and Monsoon season, although few species show evenness throughout the seasons.
