Ecology considers how organisms of the same species interact with each other, how organisms of different species in the same space interact, and how multiple communities interact to make up an ecosystem, information crucial in understanding how biodiversity affects ecological function. In over 120 articles, Principles of Ecology addresses topics including:
- Human Ecology
- Social Ecology
Ecology and evolutionary biology are considered the "sister disciplines" of the life science because of their focus on natural selection, adaptation, populations, and inheritance, all of which inform the way in which an "evolutionary tree" is drawn, and explains why the taxonomy developed by Linnaeus is still evolving today.
