affect the young more than the elderly in a population,

thereby affecting recruitment

16
Q

Exponential growth

A

J-shaped curve (only happens when a disturbance

occurs– foreign species, habitat change, removal of predators)

17
Q

Carrying capacity (K)

A

maximum number of individuals a habitat can support

18
Q

Logistic Growth

A

S-curved growth curve, population

growth decreases as density reaches carrying capacity

19
Q

Critical Number

A

minimum number of individuals a

species needs to stay a healthy population

20
Q

r - Strategists

A

spend most of their time in exponential growth, maximize reproductive life, minimum life

21
Q

K - Strategists

A

maximize lifespan, produce less young, live longer

22
Q

Late Loss

A

K-strategists, produce few young & care for
them until they reach reproductive age
also called Type I

23
Q

Constant Loss

A

intermediate reproductive strategies with fairly constant mortality
also called Type II

24
Q

Early Loss

A

r-strategists with many offspring, high infant mortality and high survivorship
also called Type III
