Lecture 7

Question 1

What is competition? How does it effect biodiversity? (decreases biodiversity)

Question 2

Chart between competition, predation, and mutualism

Question 3

Define Intraspecific competition. Relate to logistic graphs

Question 4

Define interspecific competition. Relate to lotka volterra

Question 5

Define scramble/exploitative competition. Example of squirrels and birds

Question 6

Define contest/ interference competition. Example of ants

Question 7

What does the lotka volterra model depict? How does it add to logistic graphs?

Question 8

Equations for lotka volterra vs logistic. What does the second breaking term mean?

Question 9

What does the alpha value measure and what is it called? Example?

Question 10

What are the four possible outcomes of the lotka volterra model at equilibrium (when the population is no longer changing)?
-To coexist what does this mean for intra and inter specific comp?

Question 11

Define equilibrium graphically

Question 12

Define stability in terms of equilibrium

Question 13

Define coexistence in terms of equilibrium

Question 14

What is character displacement? Example of darwins finches

Question 15

What is the paradox of the plankton/ rainforest in terms of competitive exclusion?

Question 16

Example of gauses protozoa competition experiment (3 outcomes?)

Question 17

Difference of competion exclusion in nature and in lab

Question 18

Cornell 1961 barnacle experiment. What did this say on comeptition and limits between the chthalamus and balanus species

Question 19

How does competition effect the community composition and species richness/diversity?
