Stability

Question 1

What are issues with diversity?

Answer 1

Lots of rare species

Number of species increases non-linear with sampling

Question 2

What is productivity?

Answer 2

A rate of plant biomass production per area

OR

NPP = C/ha/year

Question 3

What does productivity-diversity use as a metric of biodiversity?

Answer 3

Richness

Mostly focusses on plants

Question 4

What are the possible relationships between biodiversity and productivity?

Answer 4

U-shaped

Negative

None

Positive

Hump-shaped

Question 5

When is an ecological system stable?

Answer 5

If it is capable of returning to an equilibrium state after perturbation (resillience) or does not experience unexpected large changes in its characteristics across time (resistance)

Also measured by variability - do populations cycle a lot or not

Question 6

What are the prblems with the defintion of resillience?

Answer 6

IPCC define it as something different
