ECOLOGY
1. Ecology is the scientific study of the distribution and abundance of living organisms and how the distribution and abundance are affected by interactions between the organisms and their environment. The environment of an organism includes both physical properties, which can be described as the sum of local abiotic factors such as insolation, climate, and geology, and biotic factors, which are other organisms that share its habitat.
2. Ecology is usually considered a branch of biology, the general science that studies living organisms. Organisms can be studied at many different levels, from proteins and nucleic acids, to cells, to individuals, and finally at the level of populations, communities, and ecosystems, to the biosphere as a whole.
3. Ecology is a multi-disciplinary science. Because of its focus on the higher levels of the organization of life on earth and on the interrelations between organisms and their environment, ecology draws heavily on many other branches of science, especially geology and geography, meteorology, genetics, chemistry, and physics.
As a scientific discipline, ecology does not dictate what is right or wrong. However, ecological knowledge such as the quantification of biodiversity and population dynamics have provided a scientific basis for expressing the aims of environmentalism and evaluating its goals and policies.
4. Consider the ways an ecologist might approach studying the life of honeybees:
· the behavioral relationship between individuals of a species is behavioral ecology – e.g., the study of the queen bee, and how she relates to the worker bees and the drones
· the organized activity of a species is community ecology; e.g., the activity of bees assures the pollination of flowering plants. Bee hives additionally produce honey which is consumed by other species, such as bears
· the relationship between the environment and a species is environmental ecology – e.g., bees may die out due to environmental changes.
