• High biodiversity - Many plants and animals in an area.

• Low biodiversity - Low amount of plants and animals in an area​

​

​Some text here about the topic of discussion.

Biodiversity

​High - Many variations in DNA between members of the same species

Low - Few variations in DNA between members of the same species​

Genetic Diversity

​High - Many type of different species in the same area

Low - Few types of different species in the same area ​

Species Diversity

High - Many types of habitats for organisms to live

Low - Few types of habitats for organisms to live​

Ecosystem Diversity

What can genetic diversity protect against?

Genetic Diversity

The more variation in DNA between members in a species, the more protections they have from changes to their environment. ​

​

​In this picture, the brown fish and the green fish has the highest genetic diversity. If water oxygen changes, they have the best chance at surviving.

​Different DNA means some organisms have the ability to fight disease better.

Disease

​As environments change, some organisms will be able to adapt to their new environment easier

Climate Change​

​

​Different DNA means some organisms will be able to survive their predators better.

Predator Survivability

Before the industrial revolution, most moths were white and speckled black. Only some were black

1848

This white and black speckles gave them camoflauge on trees

​​1848

As the Britshed burned coal, their buildings and trees turned black and so did the moths.

​​1900

Why did the white ones start to disappear?

​​1900

​Black Peppered Moth

​Because some of the moths had different DNA variations, their population was able to survive as their environment changed.

Genetic Diversity

• Only lives in Mt. Charleston

• Is "trapped" there by the desert

• Has a limited breeding pool

• Is endangered because of climate change​

• Low genetic diversity​

Does low genetic diversity mean it is unimportant?

• A healthy ecosystem relies on all of its species to make it successful.

• The loss of one organism can breakdown the structure of our food webs. ​
