Introduction to Ecology
- The Organism and Its Environment
- Ecological genetics
- Plant Adaptations
- Animal Adaptations
- Physical Environment
- 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.
- Solar radiation: The
electro-Magnetic Energy
- Albedo, Insolation, PAR,
Shortwave vs Longwave
- Earth's Axis 23.5' Tropic of Cancer (N), Tropic of
Capricorn (S)
- Elevation and Temp
- Humidity
- Latent Heat, Evaporation, Condensation, Vapour pressure, Saturation Vapour Pressure,
Relative Humidity, Dew Point Temp.
- Precipitation
- Snow and Ice
- ITCZ: Near EQ NE trades meet SE trades in a narrow
high precip region.
- After raining in ITCZ ascending air mass cool, splits N&S subtropical high regions cool air
descends= 2 belts of dry climate
- Altitude: Distance Above Earth's Surface
- Elevation: Distance Above Sea Level
- Air Temp in troposphere Decreases w/Elevation
- Atmospheric Air Pressure: Total Air Mass
Above Point. Elevation Increases, Air Mass
Decreases, Air Pressure Drops.
- Decrease in Temp w/Elevation
caused by greater air pressure @
surface, faster air molecules &
warmth of longwave rad declines
with elevation.
- @ certain elevations temp abruptly changes, atmospheric regions
- Troposphere & Stratosphere (Climate), mesosphere, thermosphere
- Adiabetic Cooling
w/Elevation+Adiabetic Lapse
rate
- Atmospheric Circulation
- Coriolis Effect
- Trade winds named after direction they come from, i.e.
Westerlies POor-Ferrel. HAD. LOW EQ. & a SUB-par HIGH
- Ocean Currents: Solar energy, wind and Earth's
rotation create.
- Gyres
- Irregular Climatic Variation
- El nino+Warm water
- El Nina= cold water
- Aquatic Environment
- Water Cycle
- Properties of Water
- High Specific Heat= Moderating effect i.e. Maritime Climate.
- Water @ densest @4'c, any colder and density decreases.
- Temperature
- Tides
- Estuaries
- Terrestrial Environment
- Challenges and Opportunities
- Light and Vegetation
- Soil
- History
- 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
- Growth and processes
influenced by
conditions, conditions
influence access to
resources, protect from
hazards
