Chapter 56- Ecology of Individuals and Populations Flashcards
1
Q
Population
A
-groups of individuals of the same species in one place
2
Q
3 characteristics of Pop. ecology
A
- Pop. range, area throughout which a pop occurs
- patter of spacing/density of individuals
- how pop. changes in size throughout time
3
Q
Random spacing
A
-individuals do not interact strongly with one another, not common
4
Q
Uniform spacing
A
- behavioral interactions, resource competition
- not too common
5
Q
Clumped spacing
A
uneven distribution of resources, very common
6
Q
Natality rate
A
-birth rate
7
Q
r=(b-d)+(i-e)
A
- applies to populations with no growth limits
- r=rates of pop increase
- b=birth rate
- d=death rate
- i=immigration
- e=emigration
8
Q
Biotic potential
A
maximum growth rate of pop under ideal conditions (theoretical, doesnt happen)
9
Q
Carrying capacity
A
-number of individuals an environment can support
