Introduction to Ecology
  1. The Organism and Its Environment
    1. Ecological genetics
      1. Plant Adaptations
        1. Animal Adaptations
        2. Physical Environment
          1. Climate: Continental= w/i interior of land masses and temp range is great b/c no large water bodies to regulate temp. Maritime+ Coastal, low range of temp, high precipitation.
            1. Solar radiation: The electro-Magnetic Energy
              1. Albedo, Insolation, PAR, Shortwave vs Longwave
                1. Earth's Axis 23.5' Tropic of Cancer (N), Tropic of Capricorn (S)
                2. Elevation and Temp
                  1. Humidity
                    1. Latent Heat, Evaporation, Condensation, Vapour pressure, Saturation Vapour Pressure, Relative Humidity, Dew Point Temp.
                    2. Precipitation
                      1. Snow and Ice
                        1. ITCZ: Near EQ NE trades meet SE trades in a narrow high precip region.
                          1. After raining in ITCZ ascending air mass cool, splits N&S subtropical high regions cool air descends= 2 belts of dry climate
                        2. Altitude: Distance Above Earth's Surface
                          1. Elevation: Distance Above Sea Level
                            1. Air Temp in troposphere Decreases w/Elevation
                              1. Atmospheric Air Pressure: Total Air Mass Above Point. Elevation Increases, Air Mass Decreases, Air Pressure Drops.
                                1. Decrease in Temp w/Elevation caused by greater air pressure @ surface, faster air molecules & warmth of longwave rad declines with elevation.
                                2. @ certain elevations temp abruptly changes, atmospheric regions
                                  1. Troposphere & Stratosphere (Climate), mesosphere, thermosphere
                                  2. Adiabetic Cooling w/Elevation+Adiabetic Lapse rate
                                  3. Atmospheric Circulation
                                    1. Coriolis Effect
                                      1. Trade winds named after direction they come from, i.e. Westerlies POor-Ferrel. HAD. LOW EQ. & a SUB-par HIGH
                                      2. Ocean Currents: Solar energy, wind and Earth's rotation create.
                                        1. Gyres
                                        2. Irregular Climatic Variation
                                          1. El nino+Warm water
                                            1. El Nina= cold water
                                          2. Aquatic Environment
                                            1. Water Cycle
                                              1. Properties of Water
                                                1. High Specific Heat= Moderating effect i.e. Maritime Climate.
                                                  1. Water @ densest @4'c, any colder and density decreases.
                                                2. Temperature
                                                  1. Tides
                                                    1. Estuaries
                                                    2. Terrestrial Environment
                                                      1. Challenges and Opportunities
                                                        1. Light and Vegetation
                                                          1. Soil
                                                        2. History
                                                          1. Darwin influenced by Malthus's assessment on pops under limiting conditions, Lyell's theory on the earth's age, evolutionary theory->ecology as formal science
                                                            1. Growth and processes influenced by conditions, conditions influence access to resources, protect from hazards
