Phylogenetic classification system
Domain, kingdom, phylum, class, order, family, genus, species
How does the phylogenic classifications system arrange groups into their evolutionary origins ?
Arranges species into groups based on their evolutionary origins and relationships.
Smaller groups are placed within larger groups with NO overlap between groups
Species
A group of similar organisms that can breed together to produce fertile offspring
Binomial name
A two-part scientific name - genus, species (eg. Homo sapiens)
Name can be universally identified
Courtship
Mechanism of species recognition necessary to ensure successful mating
Courtship behaviours allow species to…
Recognise members of their own species
Indenting a mate capable of breeding
Synchronise mating
Form a pair bond
biodiversity
The variety of organisms living in a particular area or habitat
Habitat
Place where individual of a species live with a specific set of biotic and abiotic factors
Species richness
Measure of the number 0f different species in a community
Community
Number of organisms of all species that live in the same area
Index of diversity
Used to calculate the biodiversity of a community
Impact of modern farming practises on biodiversity
Ponds, hedgerows, and woodland are removed
Marshes and wetlands are drained
non selective pesticides kill non-target species
