Elaine Chung AP Bio September 9, 2009 Unit Eight: Ecology Chapter 46: An Introduction to Ecology: Distribution and Adaptations of Organisms I. Ecology: the scientific study of the interactions between organisms and their environments A. Environment includes: 1. Abiotic factors i. Temperature, light, water, nutrients 2. Biotic factors i. All the other organisms that are part of any individual's environment. a. Competition, adaptation, interaction, etc. II. Basic Ecology Provides a scientific context for evaluating environmental issues. A. Problems with the environment 1. Acid precipitation, famine, overpopulation, land misuse, endangered species, toxic waste, etc. 2. Works that spread awareness i. Rachel Carson's Silent Spring ii. Photographs taken by Apollo astronauts III. Ecological research ranges from the adaptations of organisms to the dynamics of ecosystems. A. Four increasingly comprehensive levels of study 1. Organism ecology- concerned with the behavioral, physiological, and morphological ways in which individual organisms meet the challenges posed by their abiotic environment. 2. Population- a group of individuals in a particular geographic area that belong to the same species. Population ecology concentrates mainly on factors that affect population size and composition.

3. Community- all the organisms that inhabit a particular area; populations of different species 4. Ecosystem- all the abiotic factors in addition to the community of species that exists in a certain area. B. Ecology, an Experimental Science 1. Experiments are constantly being conducted to discover more information about ecology. 2. Mathematical models, computer programs, simulations used. 3. As more information is discovered, more complex questions and problems arise. i. Discussing the importance of forests, and how much can be sufficient. C. Ecology and Evolution 1. Field of ecology and evolutionary biology are tightly linked to each other. 2. Research provided by ecologists inspired Charles Darwin to come up with his theory. 3. Ecological time- effects over the longer scale of evolutionary time. 4. Evolutionary Theme: i. The present distribution and abundance of organisms are products of both long- term evolutionary changes and ongoing interactions with the environment. IV. Climate and other abiotic factors are important determinants of the biosphere's distribution of organisms. A. Biosphere- entire portion of Earth that is inhabited by life; the sum of all the planet's communities and ecosystems. B. Biomes- the major types of communities and ecosystems that are typical of broad geographic regions 1. Coniferous forests, deserts, and grasslands. C. Sunlight is crucial for organisms to survive; they derive their energy from it. D. Global, regional, season Variations in climate
