Physical factors such as light, temperature and water.
1 of 23
Albedo
A measure of the reflectivity of a surface. More reflective surfaces have higher albedos.
2 of 23
Antarctic Treaty (1959)
An international agreement to protect and manage Antarctica.
3 of 23
Biodiversity
A measure of the variety and abundance of wildlife species.
4 of 23
Biomass
The total mass of living or recently living material in an area.
5 of 23
Biotic factors
Biological factors such as food and disease.
6 of 23
British Antarctic Survey (BAS)
UK research organisation that operates in Antarctica.
7 of 23
Carbon sequestration
Any process that is used to remove carbon dioxide from the atmosphere, such as afforestation or underground storage.
8 of 23
CITES
The Convention on International Trade in Endangered Species (of wild fauna and flora).
9 of 23
Ecotourism
Tourism intended to have low environmental impact, usually involving seeing wildlife.
10 of 23
Gene pool
The total variety of different genes in all the members of a population.
11 of 23
LEDCs
Less Economically Developed Countries.
12 of 23
Microclimate
A small area with a climate that is different from the surrounding area.
13 of 23
Niche
The niche of a species is the role it plays in its habitat, which includes how it makes use of resources and responds to the other species in its habitat.
14 of 23
No-Take Zone
An area where the catching or removal of species is banned, e.g. areas where fishing is not allowed.
15 of 23
Nutrient
Any chemical that is essential to an organism for growth or for metabolic processes.
16 of 23
Plankton
Organisms that drift in the surface layers of the sea or other water bodies.
17 of 23
Slash and burn farming
Farming in a forest where a clearing is created by burning and is farmed for a few years until nutrient depletion and weed growth cause it to be abandoned, as a new clearing is created elsewhere.
18 of 23
Species
A group of organisms that resemble each other more than other organisms and naturally interbreed to produce fertile offspring.
19 of 23
Symbiosis
A relationship between organisms of different species that live together. One benefits while the other species may benefit, be unaffected or suffer.
20 of 23
Transpiration
The loss of water by evaporation from the stomata of leaves.
21 of 23
Upwelling
An upwelling is where deep ocean water comes to the surface, often carrying nutrients and causing rich algal blooms.
22 of 23
UV light
UV is short wavelength radiation emitted by the sun. Its energy can cause chemical reactions to take place, such as in the ozone layer or sunburn and DNA damage.
