Airborne algae are spread in the environment by various local air movements. The post-monsoon season (i.e., the months of October, followed by November, September, December, and August) was the most favorable climate for the occurrence of airborne algal species from the Chlorophyta domain and was having a higher growth rate. Currently, biomass feedstock from forestry or crops, or agricul- tural...

The overall accuracy of the classification is between 89.04% to 95.24%. Historical comparison of Land Use Land Cover (LULC) change in- dicates the interaction between the environment and humans in that region, which is very important for natural resources management and sustainable development ( Gillanders et al., 2008 . Remote sensing techniques in LULC classification significantly reduce the cost and...

alligator gars and bull sharks (mainly teleost diet). Elevated levels (45 × higher) of nervonic acid (24:1n9) also placed the trophic ecology of catfish and red drum closer to the base of the marine/estuarine food web of Sabine Lake, as compared to alligator gars and bull sharks. The multivariate correlational analysis of pollutant body-burdens and fatty acid levels showed no...
