Enlist any two Quantitative analytical community characters.
Answers
Generally, analysis of community characters is being done for two specific purposes:
(i) To record variation within and between communities and
(ii) For naming and classifying communities.
Analytical characteristics are those features of community which can be observed or measured directly in each aspect. It involves measurements of various characters in sample plots, commonly known as quadrats. Measurements made in sample plots (quadrats) are scientifically processed to reflect the characteristics of the entire community.
Two sets of characters, viz.:
(i) Analytical, and
(ii) Synthetic are studied in a community at the same time.
1. Analytic Characters:
They are directly observed or measured in sample plots. They include kinds and number of species, distribution of individuals, number of individuals, height of plants, etc.
2. Synthetic Characters:
They are derived from the measurements of analytic characters and utilise data obtained in the analysis of a number of stands.
Analytical characters are of two types:
(i) Qualitative:
They are based on non-quantitative observations, e.g., species composition and stratification of vegetation. They are expressed only in qualitative way.
(ii) Quantitative:
They are expressed in quantitative terms. They are measured. The major quantitative characters include frequency, diversity, cover, biomass, leaf size, abundance, dominance, etc.
