An Introduction To Ecology

Ecology – study of interactions between organisms and environment. Consists of abiotic (nonliving; i.e. temperature, light, etc) and biotic (living) factors.

http://www.apsnet.org/education/illustratedglossary/PhotosE-H/forestdecline.htm

Population – group of individuals of same species living in an area. Community – all organisms of all species that live in an area. Ecosystem – above plus abiotic factors. Biosphere – sum of all ecosystems.

Distribution affected by temperature, water, sunlight, wind, and rocks and soil. Type of each will determine what can live there.

Temperature and water are biggest factors. Biomes – major types of ecosystems. Determined by proximity to equator, closeness to ocean, mountains, etc.

http://z.about.com/d/geography/1/0/V/A/equator.jpg

Aquatic biomes 2 types – marine and freshwater. Stratified vertically – photic zone (light) and aphotic zone (little light). Bottom of aquatic is benthos – food is detritus that falls from above.

Freshwater – close to shore – littoral zone. Open water – limnetic zone. ALakes classified by nutrients – 1 - eutrophic – shallow and nutrient-rich; 2oligotrophic – deeper and nutrient-poor.

Eutrophic lake http://www.spatial.maine.edu/~snoox/images/eutrophic_lake.jpg

* BWetlands – area covered with water; supports plants. CEstuaries – area where freshwater meets ocean. Intertidal zone – land meets water. DCoral reefs – dominated by coral.

Wetlands http://www.usbr.gov/dataweb/assets/images/Wetlands.jpg

Estuary http://www.cop.noaa.gov/images/estuaries.jpg

Coral Reef http://212.84.179.117/i/Coral%20Reef.jpg

EOceanic pelagic biome – away from shore. Abyssal zone – lowest part of benthos; deep-sea hydrothermal vents help chemoautotrophic organisms.

Abyssal zone http://206.110.20.50/web/schuh/students/jonathan/Monsters/MonstersofthDeep/seaslug.JPG

Terrestrial biomes Defined vertically from the canopy at top to the permafrost at the bottom. ATropical forest – little light reaches ground because of deep canopy. Rainfall determines life in area.

BSavanna – scattered trees and grasses. Fire helps increase diversity. Has rainy season. CTemperate grassland – seasonal drought, fires prevent tree growth. Most used for farming.

Savanna http://www.plantzafrica.com/vegetation/vegimages/savanna3.jpg

Grasslands http://earthobservatory.nasa.gov/Laboratory/Biome/Images/picgrassland.jpg

DDeserts – sparse rain, some are cold. Plants have structures to allow survival (i.e. water storage, alternative forms of photosynthesis) EChaparral – evergreen shrub; long, hot, dry summers with fires.

Desert http://pangea.stanford.edu/~hsiao/desert.jpg

Chaparral http://www.cpluhna.nau.edu/images/semiaridgrasslands92rw.jpg

FTemperate deciduous forest – small mammals, leaves fall during autumn. GConiferous forest – cone-bearing trees, trees have needles. HTundra – permafrost covers ground, low diversity.
