Week 16, November 21-November 25, 2011
Unit 7: Speciation and Population Biology
Concept 4: Biological Evolution
Understand the scientific principles and processes involved in biological evolution.
S4-C4-PO2. Explain how genotypic and phenotypic variation can result in adaptations that influence
an organism’s success in an environment.
S4-C4-PO3. Describe how the continuing operation of natural selection underlies a population’s
ability to adapt to changes in the environment and leads to biodiversity and the origin of new species.
Topics
Population growth and dynamics
Limiting factors
Carrying capacity
Process of speciation

Standards: S4-C4-PO2, S4-C4-PO3
Today’s vocabulary:
Weather: the condition of the Earth’s atmosphere at a particular place and time.
Climate: average year after year conditions of temperature in an area.
Greenhouse effect: heat retained in atmosphere due to CO2, methane, water vapor and other gases.
Polar zone: cold climate where the sun’s rays strike earth at a very low angle.
Temperate zone: moderate climate zone between polar zone and tropics.
Tropical zone: warm climate zone that receives direct or nearly direct sunlight year round.
Biotic factor: biological factor that affects organisms in an ecosystem.
Abiotic factor: a non-biological factor that affects organisms in an ecosystem.
Habitat: area where an organism lives, includes biotic and abiotic factors.
Niche: a term describing the relational position of an organism's species.
Resource: is a source or supply from which benefit is produced.
Competitive exclusion principle: two species competing for the same resources cannot coexist if other
ecological factors are constant.
Predation: the relationship between two groups of animals in which one species hunts, kills, and eats the
other.
Symbiosis: a close association of animals or plants of different species that is often, but not always, of mutual
benefit.
Mutualism: a relationship between two organisms of different species that benefits both and harms neither.
Commensualism: the relationship between organisms of two different species in which one derives food or
other benefits from the association while the other remains unharmed and unaffected.
Parasitism: A form of symbiosis in which one organism (called parasite) benefits at the expense of another
organism usually of different species (called host). The association may also lead to the injury of the host.
Ecological succession: A gradual process incurred by the change in the number of individuals of each species
of a community and by establishment of new species populations that may gradually replace the original
inhabitants.
Primary succession: the development of plant and animal life in an area without topsoil; the development of
biotic communities in a previously uninhabited and barren habitat with little or no soil.
Pioneer species: A pioneer species is a species that is first to establish itself in an area where nothing is
growing-or in an area that has been devastated by fire, flood, plowing etc.
Secondary succession: succession following a disturbance that destroys a community without destroying the
soil.

November 22
Standards: Standards: S4-C4-PO2, S4-C4-PO3
Today’s vocabulary:
Biome: climatically and geographically defined as similar climatic conditions on the Earth, such as communities of plants,
animals, and soil organisms,[1] and are often referred to as ecosystems.
Microclimate: a local atmospheric zone where the climate differs from the surrounding area.
Canopy: dense covering formed by leafy tops of tall raintrees.
Understory: layer in rain forest formed by shorter trees and vines.
Deciduous: term used to refer to a tree that sheds its leaves during a particular season each year.
Coniferous: trees that produce seed bearing cones and needle-like leaves.
Humus: material formed from decaying leaves and other organic matter.
Taiga: another name for the boreal forest.
Permafrost: layer of permanently frozen subsoil in the tundra.
