DISCUSSION
Wetlands in urban landscapes are often neglected for biodiversity exploration and conservation priorities, even though they are biodiversity rich habitats. Current study reports Nitzschia taylorii and N. williamsii abundantly inhabiting Begur and Thalghattapura wetlands respectively. These wetlands are with moderate to high trophic conditions and thus these two taxa can be considered as indicator of high levels of trophic status. Further taxa such as Nitzschia palea (Kützing 1844: 63) Smith (1856: 89), N. intermedia Hantzsch ex Cleve & Grunow (1880: 95), N. dissipata (Kützing 1844: 64) Grunow (1862: 561) and N. acicularis (Kützing 1844: 63) Smith (1853: 43) are widely recognized as pollution tolerant taxa and often considered as key species in water quality indices (Prygiel et al., 1999, Saros and Fritz, 2000, Lavoie et al., 2009, Wang et al., 2005, Mayama et al., 2011). Studies on pollution tolerant genera such as Nitzschia will aid further in autecological and biogeographical studies apart from developing diatom based water quality indices for wetlands of Peninsular India.
