Subaerial cyanobacteria on the monuments and exterior surface of building facades of Odisha state, India Subaerial cyanobacteria on exterior surface of monuments and building facades have great importance under extreme conditions to enhance their colonization and diversity. Work was undertaken to assess the cyanobacteria diversity of Western Odisha especially concerning to monuments and building facades, and their comparative analysis. In total fifty subaerial cyanobacterial taxa belonging to 21 different genera of five orders were documented. Out of these 19 taxa were documented as new distributional records from the subaerial habitats of Odisha. Morphologically, 50% of taxa were filamentous heterocystous forms, followed by 26% colonial forms and 24% filamentous non-heterocystous forms. Diversity analysis revealed that cyanobacteria diversity was relatively higher in building facades rather than the monuments which may be resulted due to variation in substrate composition and exposure to climatic factors. A comparative distributional analysis of so far documented cyanobacteria from various subaerial habitats of Odisha revealed a habitat specificity is observed among the cyanobacteria from the monuments which represent biofilms with less common taxa.

在印度奥里萨邦的纪念碑及建筑立面外表面上的浮游蓝藻，这类浮游蓝藻在极端条件下对纪念碑及建筑立面的栖息地扩展和多样性具有极其重要的意义。本研究旨在评估奥里萨邦西部地区的蓝藻多样性，特别是针对纪念碑及建筑立面，并进行了比较分析。共记录了50种浮游蓝藻分类群，隶属于五个目中的21个属。其中，19种分类群被记录为奥里萨邦地表栖息地的新分布记录。形态学分析表明，50%的分类群为丝状异形胞型，其次是26%的群体型，以及24%的丝状非异形胞型。多样性分析揭示了蓝藻的多样性在建筑立面上相对较高，而纪念碑上较低，这可能是由于基质的组成和气候因素的暴露差异所致。对迄今为止已记录的奥里萨邦各种地表栖息地蓝藻的比较分布分析表明，纪念碑上的蓝藻呈现出较强的生境特异性，这些蓝藻构成的生物膜包含较少见的分类群。
