Distance-Based Analysis of Soil Mycofloral Communities of Hot Arid Region of India

Manish Mathur, Alkesh Tak, Praveen Gehlot

Abstract


Ecological dynamics of soil fungal communities have been explored from different hot arid regions of the world with different scientific approaches along with bi or multi-directional cause and effect relationships. In general, such studies documented large heterogeneity in soil fungal population which were linked with various bottom-up (vegetation, climatic features, land use and anthropogenic) and top down factors (soil physical-chemical properties) and hence at large geographical level, generalization about their population dynamics cannot be figure out. Thus, a method is required which not only can provide a cumulative ecological grouping of fungal species cultivated from different zones and land use but can also reduce the non-normality of original data set. With such approach, a researcher can provide a confident threshold population list and grouping for a large geographic region. Population dynamics of 69 soil fungal species (4 zone) were evaluated pertain to three land-use types with their abundance and modified functional dispersion (FDM) values. Our modified algorithmic based approach is a pioneer one for fungal population and provides an integrated weighted ecological grouping. Such grouping inherently accommodates spatial and land-use attributes. Our FDM also significantly relate with species specific spatial pattern.
