Biodiversity

Question 1

Interspecific variation

Answer 1

The differences between species

Question 2

Intraspecific variation

Answer 2

Variation between members of the same species

Question 3

Continuous variation

Answer 3

Variation where there are two extremes and a full range of values in between

Question 4

Discontinuous Variation

Answer 4

Where there are distinct categories and nothing in between

Question 5

SID

Answer 5

n = Number of organisms of the species
N = Total number of organisms

Question 6

Comparing stability of SID in contrasting areas

Answer 6

Higher SID = more stable

Question 7

Suggest measures that could be put in place to protect the biodiversity of moorland habitats

Answer 7

Give area protected / Red listed status

In Situ:
- Education
- ref. restoration
-limit access/ no hunting

Ex Situ:
- remove seeds from endangered plants and store in seed banks
- Captive species programmes / species reintroduction

Question 8

Mark - Recapture

Answer 8

C1 = Captured individuals
C2 = Recaptured
C3 = Already marked

Total population size estimate = (C1 x C2) / C3

Question 9

Different types of sampling methods

Answer 9

Opportunistic = decisions prior
Stratified = dividing habitat into areas that appear different
Random = Random coordinates
Systematic = samples taken at fixed intervals
