Studied by 13 peopleEcological Diversity
The variety of ecosystems found in an area or on the earth.
Biological Diversity
Variety in the earths species.
Biological Diversity
Variety in the earths species
Functional Diversity
Variety of processes within an ecosystem
Genetic Diversity
Variety of genes in a population
Species Diversity
Number and variety of species
Ecological Diversity
The variety of ecosystems found in an area or on the earth
Biological evolution
How life changes over time and it can be seen through the differences in genetic characteristics
Natural selection
Individuals with certain traits are more likely to survive and reproduce under a certain set of environmental conditions
Fossils
Physical evidence of old organisms
Fossil Record
Entire body of fossil evidence
Mutations
Random changes in DNA molecules
Natural selection
Acts on individual
Genetic Resistance
Ability of one or more members of a population to resist a chemical designed to kill it
Adaptation
An organism becomes better suited to its habitat (where it lives) from a genetic trait
Differential Reproduction
A phenomenon in which people who possess adaptable genetic qualities have more viable offspring than people who have not
Speciation
One species splits into two or more species
Geographic Isolation
Physical isolation of populations for a long period
Reproductive Isolation
This leads to an inability to produce proper offspring when two individuals from separate species mate
Extinction
Process in which an entire species ceases to exist
Endemic Species
Found only in one area, particularly vulnerable to extinction
Background Extinction
Typical low rate of extinction
Mass Extinction
Significant rise above background level
Species Diversity
The number of different species present in an ecosystem and the relative abundance of each of those species
Species Richness
The number of different species in a given area
Species Evenness
Comparative number of individuals of each species present
Ecological Niche
Everything that affects survival and reproduction
Generalist Species
Wide range of tolerance, broad species
Specialist Species
Narrow range of tolerance, narrow niche
Indicator Species
Provides us with early warnings of environmental damage
Native Species
Normally live in an ecosystem
Nonnative Species
Not native
Keystone Species
Have a large effect on the types and abundances of other species
Foundation Species
Species that create habitats and cause a positive effect on diversity
Functional Diversity
Variety of processes within an ecosystem
Genetic Diversity
Variety of genes in a population
