Week 5

Question 1

What is a possible consequence of physiological incompatibility in species due to climate change?

Answer 1

Lack of genetic or phenotypic variation to respond

Species may not be able to adapt to new environmental conditions.

Question 2

What can result from a mismatch in timing of species interactions?

Answer 2

Dependence on other species for food or pollination may be disrupted

This can lead to ecological imbalances and affect survival.

Question 3

What happens when habitat changes occur more rapidly than dispersal?

Answer 3

Species may not be able to relocate or adapt quickly enough

This can lead to population declines or extinction.

Question 4

What is a potential risk for alpine plants in response to climate change?

Answer 4

Mismatch between flowering times and pollinator availability

This can affect reproduction and survival rates of the plants.

Question 5

What may happen to plants that flower too early due to climate change?

Answer 5

They might be caught and killed in late frosts

This can lead to significant losses in plant populations.

Question 6

What was the survival rate of plants under warm and dry conditions?

Answer 6

31-56% survives

This is significantly lower compared to other conditions.

Question 7

What was the survival rate of plants under more favorable conditions?

Answer 7

78-92% survived

Indicates that extreme drought conditions lead to higher mortality.

Question 8

True or False: Extreme drought conditions can lead to population declines in alpine plants.

Answer 8

True

High mortality rates observed under extreme drought conditions.
