Regeneration of plantlets from leaf disc and internode explants of
Phyllanthus amarus Schum. & Thonn.

Abstract :

The species diversity (H’) of birds in the study area was related to the insects’ abundance by comparing the yielding capacity of crop lands in natural and enclosed plots. Scan sampling (Altmann 1974) method was adopted to record birds and the method of Pradhan (1991) was followed to estimate insects’ abundance. The study indicated the occurrence of 64 species of birds comprising omnivores, insectivores, carnivores, granivores, and frugivores. The species diversity (H’) of birds ranged from 0.683 to 1.789 and the variations in the abundance of insects indicated no significant difference among seasons (P>0.05). The mean yielding capacity increased from 15.25 to 24.50% in the enclosed plots. A comparison of yield in natural and enclosed plots revealed an increase in yield ranging from 8.33 to 40.00%.
