1. How do we study ecology? Observation: What lives here? How many individuals of each species are there? How do they interact w/each other? Experiments: These are used to test a hypothesis. Experiments may be artificial or real world. Modeling: Models of natural phenomena help ecologist understand the natural environment on a smaller scale.

3. Indirect Methods Satellites: Remote sensing allows ecologists to study large scale environments using precision instruments.Satellites Photography: Using remote cameras allows biologists to study animals in their natural habitat without disruption. Weather Stations: Allow scientists to study the climate and weather of each ecosystem. Radio collars: Allow biologist to track the movements and migratory patterns of different animal species.

5. Indirect Methods GIS: Geographic Information Systems - GIS is a system of hardware and software used for storage, retrieval, mapping, and analysis of geographic data. Spatial features are stored in a coordinate system (latitude/longitude, state plane, UTM, etc.), which references a particular place on the earth.

6. Indirect Methods Remote Sensing: A means of acquiring information using airborne equipment and techniques to determine the characteristics of an area. Aerial photographs from aircraft and satellite are a common form of remote sensing.
