Abstract

 

Studies were conducted between (September, 2017 to October, 2018) to investigate the variation in the compositional distribution of macrophyte communities in relation to the nutrient contents in the water and sediments of Mairuwa and Gwaigwaye reservoirs, Funtua located in the Northern vegetation of Nigeria.  All the nutrients from sediments were analyzed using Standard procedures using  Spectrophotometer, flame photometer and titration methods. Nitrogen, Phosphorus and Calcium were higher in Mairuwa reservoir than in Gwaigwaye; while Potassium on the other hand, was higher in Gwaigwaye than in Mairuwa reservoir. Magnesium was not detected in either of the two reservoirs. The modified method of flora collection was used with a random sampling technique. The correlation analysis indicated that the distribution and abundance of aquatic macrophyte composition were significantly (P
