Lecture 26: Evolutionary Conservation Biology

Question 1

Components of E.C.B

Answer 1

1. Preserving for evolutionary history/diversity
2. Preventing inbreeding depression
3. Incorporating contemporary (rapid) evolution

Question 2

Preserving for evolutionary history/diversity

Answer 2

EDGE: evolutionary distinct, globally endangered

• ensures there is variation within species
• there are places with high/unique phylogenetic diversity

Question 3

Preventing interbreeding depression

Answer 3

• increase population size
• avoid inbreeding
• genetic rescue (idea that you have small inbred population, you bring outbred individuals to increase allele availability)

Question 4

incorporating contemporary (rapid) evolution

Answer 4

• evolution was thought to be slow by Darwin, but that was not really the case

Question 5

Rapid evolution as a foe

Answer 5

basically a bunch of resistances

- shows that there is genetic variation in everything an it keeps evolving

Question 6

Rapid evolution as a friend

Answer 6

• to adapt to your environment and become more suited

Question 7

How to match phenotype to environment?

Answer 7

1. Move to an appropriate location
2. Stay in place, but alter phenotype by:
   a) plasticity (ability of one genotype to produce more than one phenotype when exposed to different environments. ex. change time of reproduction)
   b) evolution (genetic change that causes a more suited phenotype)
