Selective advantages depend on the success of organisms in their survival, reproduction and competition. And these processes are studied in population ecology. Evolutionary ecology is one of the major topics in population biology. Systems ecology is a relatively new ecological discipline which studies interaction of human population with environment. One of the major concepts are optimization of ecosystem exploitation and sustainable ecosystem management.
Landscape ecology is also a relatively new area in ecology.
Population dynamics can be studied at the landscape level, and this is the link between landscape- and population ecology. In genetics a population is a group of interbreeding individuals of the same species, which is isolated from other groups. In population ecology a population is a group of individuals of the same species inhabiting the same area. Interbreeding is seldom considered in ecological studies of populations. The exceptions are studies in population genetics and evolutionary ecology.
