Types of species
this type of species prefers a habitat that remains constant
What is a specialist?
this type of survivorship curve has high survivability early in life followed by a rapid decline later in life?
What is Type 1?
to reach biotic potential, this type of conditions must be present
What is ideal?
this is the equation for population change
What is (birth + immigration) - (death + emigration)?
this stage of demographic transition includes slow growth with both high birth and death rates
What is Stage 1 - Pre-Industrial?
this type of species has a narrow niche
What is a specialist?
this type of survivorship curve is represented by constant loss
What is Type II?
this type of growth occurs when there are no limiting factors
What is exponential growth?
a growing population will have the highest percentage of this age group
What is pre-reproductive?
during the postindustrial stage you could describe the population growth as this
What is declining or leveling off?
this type of species reproduces later in life having only a few offspring
What is K-selected?
this type of survivorship curve has the greatest mortality early in life
What is Type III?
this occurs when a species has gone over carrying capacity
What is overshoot?
these three things impact the total fertility rate of a population
What are cost, education and employment for women, infant mortality rate, age of marriage, access to birth control, and/or religious beliefs?
during the transitional stage of development, this happens to the population growth
What is increases rapidly?
this type of species is exemplified by rodents, bacteria, and algae
What is r-selected?
this type of survivorship curve typically exemplifies an r-selected species?
What is Type III?
this determines carrying capacity
What is the amount of resources or limiting factors?
this is the equation to calculate annual rate of change in a population
What is CBR - CDR/1000 x 100?
during the industrial stage, the birth and death rate slow due to these two factors
What is improved food production and health care?
What is r-selected?
this type of survivorship curve represents humans
What is Type 1?
this happens to the growth rate as the populations nears the carrying capacity
What is decreases?
this theory stats that population growth is exponential while food production is linear
What is the Malthusian Theory?
this is why poorer families in pre-industrial countries have many children
What is to replace a pension and to take care of the parents in their old age?
