Ecological species groups The purpose of classification of species into relative ly homogeneous groups is to help people communi cate and make generalizations. In the study of TRF such a classification is particularly necessary be cause many species are represented by only a few in
Ecological Succession Definition. Ecological succession is a term developed by botanists to describe the change in structure of a community of different species, or ecosystem. The concept of ecological succession arose from a desire to understand how large and complex ecosystems like forests can exist in places known to be recently formed, such as volcanic islands.

Ecological Pyramid Definition. An ecological pyramid is a graphical representation of the relationship between different organisms in an ecosystem. Each of the bars that make up the pyramid represents a different trophic level, and their order, which is based on who eats whom, represents the flow of energy.
The ecological species concept claims that species are groups or populations that share the exact same ecological niche. The definition gets a little tricky with organisms that change niches over their development. For examples, some organisms live in the water as larvae, and on land as adults. It's sometimes expanded to include a set of niches.
The ecological species concept defines a species as a group of interrelated organisms that occupy or adapt to a single niche. For example, if a population of birds exploits two different food sources, it represents two distinct species.
A simple division of tree species into two groups or guilds is proposed pioneer and nonpioneer (or climax), based on seed germination and seedling establishment. Within each guild there is continuous variation; arbitrary subdivision by height at maturity is recommended. This classification is thought to be applicable to all tropical rain forests.
