Each can be characterized by its abundance and diversity (number of kinds) in a given ecosystem or study plot. Humans, through principles 1-8, are currently changing the climate, re-arranging its chemistry, decreasing populations of food, moving around its species, and decreasing its diversity. Each pair of species in an ecosystem can be characterized by the kind and strength of these interactions, measured as their contribution to dN/dt. Well, it can not get much simpler than this, because everything in the environment is in constant interaction. The distributions of organisms and their interactions depend on contingencies Principles of Ecology will take you through the fundamentals of ecological science from individuals to ecosystems, giving you examples from terrestrial and marine systems alongside a grounding in ecological experimental design and statistical analysis. Ecology, as a science, takes on a holistic approach to nature and problem-solving that happens in our ecosystem. Holistic means that it tries to encompass and think about as many possible factors that we know about. System behaviors must first be arrayed into different levels of organization.

Humans, and our ecosystem management abilities are highly risky, and we are not only leaving our fellow humans without energy, but we are also doing it to thousands of different plant and animal species. If things happen cyclically, that means that all problems that occur within our ecosystem always cause numerous issues. I realize every ecologist is different, and that this lays bare my own intellectual DNA on the subject.
