Abstract
This study focuses on the seasonal distribution of aerospora of Karachi city. Sampling of aeromycospora was performed at five localities within the city and multivariate techniques were employed for data analysis. The climate of Karachi is of subtropical maritime desert with three main seasons, i.e., winter, summer and monsoon. Generally, the temperature and humidity are high providing conducive environment for the growth of fungi. Pollution of various kinds, particularly unattended refuse dumping sites in city also provide favorable sites for fungal growth. A total of 10 fungal species were recorded including Aspergillus candidus, A. flavus, A. fumigatus, A. niger, A. terreus, A. wentii, Alternaria solani, Curvulari aclavata, Drechslera dematioidea and Penicillium notatum. Aerospora was dominated by Aspergillus species. Differences among localities were disclosed by cluster analysis and principal component analysis (PCA).
