The effect of urbanisation on beta diversity and functional diversity of bird assemblages in Central India
(English)Manuscript (preprint) (Other academic)
Diversity changes can be evaluated at various spatial scales, and the relationship between changes in diversity at the local, landscape and regional scales is not evident. We evaluated overall patterns of functional and beta diversity of bird assemblages along a five-stage urbanisation gradient, censused over the months of January to April in the years 2010-2012, in and around Amravati City, Deccan Plateau, Central India. Along the urbanisation gradient, bird assemblages contained more and more small species, and the share of frugivorous and omnivorous species also increased, while that of zoophagous species decreased. Diversity partitioning indicated that of the overall pattern, local (alpha) diversity accounted for 50% of the total (gamma) diversity, and urbanisation stages another 36%; the contribution of within-stage, local diversity was rather small (2.7%), indicating fairly homogeneous assemblages.
