After reading this article you will learn about:- 1. Definition of Community 2. Concept of Community 3. Structure 4. Dynamics. Definition of Community: By definition, community represents the population of all species living and interacting in an area at a particular time. Population can, within limits, adapt to changes in environmental conditions. The major driving force of adaptation to environmental [...]
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 [...]
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' [...]
