Lecture 2 - Classification And Biodiversity Flashcards
What are Species
When two things mate together or join together to make something else
What is Phylogeny
The emulation between things
Who is Carl Linnaeus
He started the modern system of putting species of organism into certain classes and groups
Each species is given a Latin name so it can be used all over the world
How to remember the classification names
Did

Soup
What his the binomial system
Each name has two parts
Genus and species
Humans belong to genus and species is sapiens
Who is Carl woese

Eukarya
What is biodiversity
The variety of living organisms in an area
Why is biodiversity is important
Needed for medicine
In Amazon rainforest there is potentially a plant that can cure cancer
Food
Maintain interdependence
What causes reduction in biodiversity
Monoculture
Climate change / global warming
Deforestation
Human pollution
Land use
How to protect biodiversity
Breeding programmes for endangered species
Recycling resources
Reduction of deforestation
Two habitats you find high number of species
Rainforest and coral reef
Equation for measuring biodiversity
D =N(N-1)/E n(n-1)
N =total number of organisms of all species
n= total number of organisms of one species
E= ‘sum of’ (add together )
What does measuring biodiversity do
Measures the richness of the number of different species in a community
