Lecture 34: Adaptation to Climate Change

Question 1

What are the main effects of climate change?

Answer 1

• increased temperature
• increased frequency of extreme weather (flooding, drought, wildfires, monsoons)

Question 2

What is assisted migration?

Answer 2

Facilitating the migration of a species to a novel range through anthropocentric action

Question 3

What are the issues with assisted migration?

Answer 3

• Northern communities have nowhere else to go
• High altitude communities cannot be moved to low altitude areas
• Causing invasions

Question 4

T or F: assisted migration is the only way for species to move north.

Answer 4

False!
Some species are already naturally migrating north

Question 5

What are the two strategies for selectively breeding wild species to adapt to increasing temperatures?

Answer 5

1. convectional breeding
2. genetic engineering

Question 6

How does crispr work?

Answer 6

Modifying traits in offspring to ensure 100% that a specific trait will be passed on (rather than 50% chance)

Question 7

T or F: species found in elevated regions of extreme climate cannot tolerate these extremes?

Answer 7

False!
Some individuals are lost in extreme weathering events but the population eventually recovers (except when the frequency increases so much so that the populations cannot recover)

Question 8

T or F: certain aquatic plants can protect against extreme weathering?

Answer 8

True!
Some plants can protect shorelines from extreme wave events

Question 9

What was the “rising of Chicago”?

Answer 9

Raising buildings and streets by regrading land to prevent flooding and water-born disease outbreaks.
