Biodiversity!
2
How many species are there in the world?
3
About 1.4 million species have been found and described by humans May be as many as 10 million species New species being discovered all the time
4
What is Biodiversity? Biodiversity is the variety of life on Earth – Can be species diversity – Genetic diversity – Ecosystem diversity We’ll focus on species diversity – the number of species in a specific area
5
What groups do you think have the most species? Plants, Mammals, Birds, Amphibians, Insects, Bacteria, Fish?
6
Diversity by Groups
7
In what habitats do you think biodiversity is highest? Lowest?
8
Global Amphibian Diversity
9
Mammal Diversity
10
In what habitats do you think biodiversity is highest? Lowest? Highest diversity is found in tropical regions near the Equator We live in a biodiversity hotspot – the California Floristic Province – Many unique plants and animals found here – Also an area that is very threatened
11
How do you measure biodiversity? Look for, identify, and count number of species Can also trap species Might be interested in: – Endemic species: species that only occur in that area – Native species: species that are originally from that specific area – Non-native species: species that have been moved around by humans
12
Emerson Bioblitz! We’re going to measure biodiversity at Emerson How many animal species are at EMS? What are the most diverse groups?
13
Emerson Bioblitz! Split into groups of 5 Count number of animal species Use field guide to identify species Record data
14
Emerson Bioblitz! Find plant-animal interaction What kinds of interactions? Draw a picture of the plant, answer questions about the plant We’ll try to identify the plant tomorrow Tomorrow: make posters showcasing the biodiversity of Emerson Middle School
