1 ECOLOGY is a study of living organisms in relation to their natural environment
2 The ENVIORMENT is all the surroundings of an organism. Living, and non-living.
3 A HABITAT is a place where an organism lives
4 A POPULATION is a group of single specific organisms living in an area
5 A COMMUNITY is all the population of plants and animals living in a particular habitat.
6 BIODIVERSITY is the range of different species living in an area. Human impact has reduced biodiversity
7 An ECOSYSTEM is the community of living organisms in an area and the ABIOTIC surroundings. It is self supporting
8.1 RANDOM SAMPLING:
8.1.1 Requires a quadrat and an identification key.
220.127.116.11 The quadrat is placed in several places throughout the whole area. Then we identify each plant species and assess the percentage cover.
18.104.22.168.1 REMEMBER - the quadrat must be placed RANDOMLY. To do this, either throw it behind you, or use random coordinates.
8.2 SYSTEMATIC SAMPLING
8.2.1 Using a transect line; for when the CONDITIONS CHANGE OVER THE STUDIED AREA
22.214.171.124 Requires a quadrat, a tape measure and and identification key
126.96.36.199.1 The tape measure is stretched across the area so that all sones are covered, this is a belt transect. The quadrat is placed at one end, and the species are identified and percentage cover is assessed, and the quadrat is moved on until the end of the belt transect.
8.3 COLLECTING ANIMALS
8.3.1 Small, crawling animals
188.8.131.52 A pitfall trap.
184.108.40.206.1 A flat sided beaker buried into the ground with stones holding up the lid.
220.127.116.11.1.1 Lid prevents water getting in - so not to kill the animals.
