This article throws light upon the seven main structures to be determined in plant community. The structures are: 1. Population Density 2. Cover and Dominance 3. Height of Plants 4. Weight of Plants 5. Volume Occupied by Plants 6. Frequency 7. Importance Value Index. Structure # 1. Population Density: The density of a species is the numerical representation of its [...]
The below mentioned article provides notes on circadian rhythm with its suitable diagram. Organisms often exhibits rhythmic behaviour in association with daily alterations of light and darkness. Interestingly, many of the rhythmic responses to day and night continue even when organisms are kept under artificially made constant light (LL) or continuous dark (DD) environment. While in some organisms these rhythmic [...]
After reading this article you will learn about the modelling of populations and their interaction in a community. The effects of different types of interaction amongst the community's component populations may be modelled in terms of their consequences for population growth and dynamics. The models used to describe the dynamics of such population fall in effect into two distinct 'families' [...]
