Flashcards in Chapter 53 - Population Ecology Deck (16):
1

Causes of uniform dispersion

territoriality

2

demography

study of the vital statistics of populations and how they change over time

3

3 basic types of survivorship curve

I - low death rate at beginning

II - constant death rate

III - high death rate at beginning

4

Life History Traits

age reproduction begins

how often reproduction occurs

how many offspring each time

5

K-Selected

density-dependent

favored at high densities

competition is stronger and live near carrying capacity

6

r-selected

density-independent

selection for traits that maximizes reproductive success in low densities

maximize r, the per capita rate of increase often found in disturbed habitats

7

Age Structure

number of individuals of each age in a population 

It's graphed by a "pyramid"

8

Demographic transition

moving towards low birth rates and low death rates

9
