What is Biodiversity? Biological diversity - “Variety of life” Three levels of Biodiversity Species diversity Genetic diversity Ecosystem diversity

Species Diversity All the species on earth, including bacteria and protists, plants, animals and fungi Ex) Warblers

Genetic Diversity The genetic variation within species and between individuals. Ex) Individuals who possess slight genetic differences may be better able to adapt to new changes, like a new disease.

Ecosystem Diversity The different biological communities and their abiotic factors (chemical & physical). Ex) A marsh ecosystem, a forest ecosystem

More biodiversity = more stability in an ecosystem What happens if one species disappears?

What happens if one species disappears?

Biodiversity in Canada Canada is home to: 198 species of mammals 440 birds 85 amphibians and reptiles 1,141 fish 100,000 species of insects and other invertebrates. ?? Bacteria and micro-organisms

Biodiversity Hotspots Areas with a high density of biodiversity compared to other regions.
