Measuring biodiversity Flashcards
(8 cards)
At what levels can biodiversity be studied at?
Habitat biodiversity, species biodiversity, genetic biodiversity
What is habitat biodiversity?
Num of different habitats found within an area
Each habitat supports a number of of different species, so greater the habitat biodiversity, greater the species biodiversity within the area
What do UK habitats include?
Meadow, woodland, streams, sand dunes
What does Antarctica’s habitat include?
Covered by an ice sheet
What is species richness? (Species biodiversity)
Number of different types of species
What is species evenness? (Species biodiversity)
How many of that species are living within an area
What does a stable habitat include?
A blance between all of the different species present
An area can differ in species biodiversity even if it has the same number of species
What is genetic biodiversity?
Variation of genes that make up a species
More genetic biodiversity within a species = Better adaptation to changing environment, more likely to survive
