Homo sapiens
Genetic Diversity - Diversity of genes within a species
Types / Ways
Heterozygousity - % of heterozygous
Genetic Polymorphism - % of difference in DNA Sequence in a population
Nucleotide Diversity - # of substitution in a DNA sequence
Cause and Effect
Genetic Bottleneck - reduction in population size
Virus / Disease outbreak
Habitat destruction
Excessive hunting
Genetic drift
Founder effect
Monoculture
Ecosystem Diversity - Diversity of a habitat in a given region
Types
Terrestial
Aquatic
Ecological niche - role of each species play. What it eats (resources), where it reproduce, relationship with other species (competitor)
Species Diversity - Diversity of different species in a given community
Measurement
Sampling, eg Quadrat sampling
Richness - Total number of different types of species in a community
Count number of different species
Evenness - Variation of abundance in individual per species
Standard deviation
Diversity
Simpson's Diversity Index, a higher (closer to 1) means higher diversity
