Species biodiversity (copy)

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
