Description
SECTION I: WHAT IS ECOLOGY AND HOW DO WE STUDY IT? Studies: observation, hypothesis, prediction, collect data, experiment, Methods of collecting data: 1. Haphazard/ convenience sampling: from convenient locations 2. Random sampling: equal chance for all individuals 3. Systematic sampling: regular intervals. SECTION II: EFFECT OF THE ABIOTIC ENVIRONMENT ON THE DISTRIBUTION OF ORGANISMS 1. Climate and biome distributions Climate: Sun rays affect the equator more than north and south poles (temperature, precipitation). Seasonal variation of temperature/rainfall is due to earth’s axis. Ocean currents/mountain currents 2. The physical environment and species distributions 1. Biomes are determined by mean precipitation and temperature b.c they determine the relationship between actual and PET. 2. Air saturation (dry/moist) related to rain and temp. More moisture needed to saturate warm air. (ie. High temp/low rain = desert). Plants moderate water flow by air saturation. 3. PET (potential evapotranspiration): 2X the temperature at a given point. IF rainfall > PET ; actual = PET. Rainfall < PET; actual
