Interaction of snail species in the agroecosystem
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2017, Vol 10, Issue 1
Abstract
This study has been carried out to understand the interspecific interaction of different snail species, time and host crop. The sampling was carried out in various agricultural fields of 24 villages of Faisalabad i.e. ditches, vegetables wheat, Sugarcane, fodder, for 6 months from March, 2011 through August, 2011.There is greater than 90 percent similarity among the wheat, sugarcane, vegetables and fodder however ditches are different from previously described crops i.e 35.58% in terms of species composition. In the months of March, June and August there is more than 90% similarity while the months of April and July form the second cluster which is nearly 90% similar. However, the species of snails in the month of May is highly different with least similarity i.e. 43.89% with the cluster 1 and 2. The presence absence data for fifteen species during six months (March-August) has been used in the agro ecosystem of Faisalabad. The variance ratio test, chi squares and association indices have been determined showing an overall positive association. As W=10.7767 and falls within the range of 7.261-25 so we accept the null hypothesis of no association during different months. However, we reject the null hypothesis of no association in different habitats as W=29.28572 and doesnot fall within the range of 7.261-25. The analysis of variance shows the association between the two variables of species accession number and time is highly significant, the association between species with the host crop is found highly significant showing synergetic effect of different factors on snail composition.
