Ecology

Ecology

the study of the interactions of organisms with their environment

7 Levels of Ecological Organization

1. organism

2. population

3. community

4. ecosystem

5. landscape

6. biome

7. biosphere

Population

all individuals of the same species in a given area

Community

all individuals of all species in an area

Ecosystem

all individuals of all species in a given area plus abiotic factors

Landscape

multiple adjacent ecosystems that may interact

Biome

all ecosystems of the same type in the world

Biosphere

all ecosystems on the planet

Dichotomous key

an identification guide to the species in a particular taxonomic group for a particular region

List the 7 ecosystems of SoCal

1. Coastal Strand

2. Coastal Salt Marsh

3. Oak Savannah

4. Riparian Woodland

5. Southern Live Oak Woodland

6. Coastal Sage Scrub

7. Chaparral

Coastal Strand location

sandy areas by the sea

Coastal Salt Marsh location

low-lying areas near the ocean; usually where freshwater meets the ocean

Oak Savannah location

usually next to large prairies near rolling hills

Riparian Woodland location

usually in a narrow band immediately adjacent to a freshwater source

Southern Live Oak Woodland location

in canyons such as Topanga and Malibu Canyons

Coastal Sage Scrub location

hillsides at lower elevations and near the ocean

Chaparral location

inland and higher elevation hillsides and ridges throughout our area

Coastal Strand abiotic conditions

high levels of salt, little shade, lots of sun

Coastal Strand plant adaptations

large vacuole in each plant cell; allows storage of extra salt

Coastal Salt Marsh abiotic conditions

high levels of salt, varying levels of water

Coastal Salt Marsh plant adaptations

large vacuole in each plant cell; allow storage of extra salt

Oak Savannah abiotic conditions

low precipitation, poor soil, frequent wildfires

Oak Savannah plant adaptations

pubescent leaves; retain moisture

Riparian Woodland abiotic conditions

dominated by trees; little sun exposure

Riparian Woodland plant adaptations

relatively large leaves; maximize sun absorption flexible/compound leaves; allows contact of sunlight from many directions

Southern Live Oak Woodland abiotic conditions

shaded by surrounding hills; limited sunlight increased moisture from rainfall that runs down nearby hills and collects in low-lying areas

Southern Live Oak Woodland plant adaptations

tall trees to catch sunlight from low elevation

Coastal Sage Scrub abiotic conditions

moisture from periodic rain/coastal fogs relatively dry excessive evaporation and sun exposure

Coastal Sage Scrub plant adaptations

pubescent leaves; retain moisture

Chaparral abiotic conditions

hot/dry summers, little rain, frequent fire

Chaparral plant adaptations

small/wavy/nearly vertically attached leaves; reduce sun exposure light in color; reflect sunlight tough/thick/folded/pubescent leaves; reduce evaporation by wind

List the 5 plants with compound leaves

1. Bladderpod

2. California walnut

3. Poison oak

4. Deerweed

5. Elderberry
