Unit 3 Populations Flashcards
Difference between generalist and specialist species
Specialist species are at advantage if habitat remains constant
Generalist species will have advantage to habitats that are changing.
K species
Large, few offspring, mature over longer period of time, extended youth and parental care
r species
small, many offspring, mature early, short life spans
Biotic potential
maximum reproductive rate of a population in ideal conditions
What type is most likely invasive species
r species
K species typically follow a…
Type 1 or Type II
r selected species typically follow a..
Type III curve
What occurs when a population exceeds its carrying capacity
overshoot occurs
What letter is represented for carrying capacity
K
Major ecological effect of population overshoot is a
dieback from lack of resources leads to famine disease and or conflict
TFR (total fertility rate) is affected by what factors?
Education, family planning, government acts
Rule of 70
70/Growth Rate = Number of years to double
Demographic transition
high to lower birth and death rates (developing occurs)
Developing countries have
high infant mortality rates and more children working
