Species
Taxonomy defintion
The theory and practice of biological classification
Phylogenetic classification order
Domain, kingdom, phylum, class, order, family, genus, species
Biodiversity definition
Number and variety of living organisms in a particular area
Species diversity
The number of different species and the number of individuals within each species within any one community
Genetic diversity defintion
The variety of genes possessed by the individuals that make up a population of a species
Ecosystem diversity
The range of different habitats from a small local one to the whole world
Ecosystem defintion
A biological community of interacting organisms in their physical environment
Species richness defintion
Is the number of different species in a particular area at a given time
What does simpson’s diversity index measure
Measures the number and evenness of species
What does a high D value represent
Stable and ancient site
What does a low D value represent
Pollution, recent colonisation, agricultural management
6 points on eutrophication
The nutrient pollutes the water leading to nutrient enrichment, leads to algal bloom, algae then die, algae are decomposed aerobically by bacteria and use up O2 in water, water becomes anoxic so fish and invertebrates die, species diversity decreases
