What is Natality?
The loss of individuals from a population in an ecosystem as a result of death.
What is Mortality?
The movement (gain) of individuals from a population of an ecosystem.
What is Immigration?
The loss (leaving) of individuals from a population in an ecosystem
What is Emigration?
A population which natality, mortality, immigration, and emigration are all present.
What is an open population?
The rate at which a population size changes.
What is population growth?
Produces a J-Shaped curve and has unlimited resources.
What is exponential growth
The formula for Population Growth...
what is..
pop growth=(natality+immigration)-(mortality+emigration)
A closed population lacks this.
What is Immigration and Emigration?
The formula for percent change in a population
What is...
Birth Rate - Death Rate / 100
Factors that may exist in an ecosystem that prevent the experimental growth of a population.
What is a Limiting Factor?
Provides information about the number of people at different ages.
What are population histograms?
How to calculate new population...
What is...
New Pop = Original Pop + Pop Growth
Factors that are related to living organisms
What is Density Dependent?
Factors that are related to the environment
What is Density Independent?
Max number of offspring per birth
What is Birth Potential?
The max number of offspring that could be produced by a species is when there are unlimited abiotic and biotic resources.
what is Biotic Potential?
The number of offspring that reach a reproductive age themselves
What is capacity for survival?
The max number of individuals of a species that can be supported indefinitely by the ecosystem and depends on the availability of resources
What is carrying capacity?
The number of times a species can reproduce in a year.
What is prcreation?
In January of 2005, the wolf population in a forest ecosystem was 77. For the remainder of the year, the following data was obtained:
Births=44 Deaths=25
Immigration= 13 Emigration=17
Calculate the population of wolves in January 2006.
What is..
The new wolf population in 2006 was 92?
In January of 2005, there was a human population of 780 in Springtown. For the remainder of that year, the following data was obtained:
Births=50 Deaths=500
Immigration= 0 Emigration=0
Calculate the population of humans in January 2006
what is....
The new human population in 2006 is 330
In January 200, the hare population in a forest ecosystem was 60. For the remainder of that year, the following data was obtained:
births=20 deaths=25
immigration=3 emigration=7
Calculate the population of hares in January 2001
what is....
The new population of hares in 2001 is 51.
The age of sexual maturity and the number of years the individual can reproduce.
What is length of reproductive life?
Consists of all the individuals of the same kind, or species, that live in a given area.
What is a population?
