Phylogeography also gives an important historical perspective on community composition.

Changes in community composition are therefore also an expected product of climate change.

"Then we were able to go back and sample those rivers and examine how community composition had changed over time."

As mentioned previously, interspecific competition has great impact on community composition and structure.

Surveys of fruiting bodies are commonly used to assess community composition and richness in many studies.

These periodic shifts in life history properties produce observable changes in community composition.

In this sense, succession theory implicitly recognized priority effects; the prior arrival of certain species had important impacts on future community composition.

Such priority effects could have dramatic impacts on community composition and food web structure.

In order to connect community composition and function in metagenomes, sequences must be binned.

The model then uses birth, death, immigration, extinction and speciation to modify community composition over time.
