Population Ecology Notes
POPULATION DENSITY, DISTRIBUTION & GROWTH.  Density is a measure of how closely packed organisms are in a population  Calculated by … DENSITY # of individuals.
IV. Limiting Factors A. What are they? 1. There are two rules of population ecology a. All populations are capable of exponential growth b. None do 2.
Populations How they grow and what affects them. Characteristics of a Population Population Density ◦ How many organisms in a specific area Geographic.
Chapter 8 Understanding Populations
 Population - an interbreeding group of individuals of a single species that occupy the same general area.  Community- interacting populations that.
Do now 1.Describe the ecosystem of Easter Island. 2.What are some factors that limited how many people can live on Easter Island?
UNDERSTANDING POPULATIONS.  Members of the same species (reproduce with one another)  Live in the same place (Geographic location)  Live at the same.
4 CHARACTERISTICS OF A POPULATION 1.Geographic Distribution/ Range- How much area does the population cover? 2.Density- How many members of the population.
POPULATIONS. 1. S curve = Logistic growth Resource availability will cause the population to level off over time When we look at how populations grow,
ECOLOGISTS STUDY ENVIRONMENTS AT DIFFERENT LEVELS OF ORGANIZATION. Population Ecology Organism  Population  Community  Ecosystem  Biome.

What makes up an ecosystem?  Biotic factors  Plants  Animals  Bacteria  Etc.  Abiotic factors  Water  Light  Temperature  Soil.

Presentation transcript:

Reproduction- making babies Reproduction- making babies. Maintains the population and continues your species

Exponential growth- growth in which the “rate of growth” rapidly increases over time. U L A T I N Time

Limiting Factors- things in nature that control the size of a population. Predators- animals that eat them Food supply Water supply Space Disease Weather Natural Disasters Humans

density dependent factors- factors relating to number of organisms in the area predation- one organism feeding on another parasitism- something hurting another disease- increases in greater population competition - for food, space

Density independent factors- doesn't relate to population size Natural disasters Temperature Oxygen content Human Interference

Carrying Capacity- the total size of a population that can be maintained in an area over a period of time. S Curve

Biotic Potential the maximum amount of population growth possible under ideal conditions in an ecosystem
