Environmental
change
- Changes in the
environment affect the
distribution of organisms
- Animals and plants experience
environmental change
- either caused by non-living
factors such as average rainfall
changing
- or living factors such as a
new predator or
competitor
- either caused by non-living
factors such as average rainfall
changing
- Can be measured using
living indicator species
- lichens measure sulfur
dioxide concentration in the
air so give a good idea of
pollution from for example
car exhausts cleaner air
means more lichens.
- invertebrate animals (E.G mayfly
larvae, rat-tailed maggots and
sludgeworms) can be used as water
pollution indicators for the
concentration of dissolved oxygen
in water. For example the cleaner a
river is the more mayfly larvae
found as it means less bacteria so
less oxygen been used up by
bacteria so more oxygen for other
invertebrates.
- lichens measure sulfur
dioxide concentration in the
air so give a good idea of
pollution from for example
car exhausts cleaner air
means more lichens.
- Can be measured using
non-living indicators
- collecting data about oxygen
levels, temperature and rainfall
allows us to measure
environmental change
- dissolved oxygen meters
are used to measure the
concentration of dissolved
oxygen in water
- satellites measure sea
coverage, snow & ice levels
accurately with a global
coverage
- dissolved oxygen meters
are used to measure the
concentration of dissolved
oxygen in water
- collecting data about oxygen
levels, temperature and rainfall
allows us to measure
environmental change
