  1. Ecosystems of the World

  2. Climax Vegetation- the natural vegetation in the last possible stage of vegetation development. • Climax vegetation is in balance with the climatic conditions. • It should change very little if left undisturbed.

  3. Climax vegetation in boreal (coniferous) forest: • * Evergreen trees • * Needle like leaves • * Thick bark • * Conical shape • * Drooping branches Climate is temperate cold winter – these trees are hardy enough to endure long winters with limited water. * needle leaves reduce surface area meaning less water loss. * thick bark reduces water loss. * drooping branches and conical shape allow heavy snow to fall off relieving the pressure.

  4. Complete # 19 on pages 102 – 103. • Boreal Forest & Tundra are wide spread in high latitudes. • Tropical Rain Forests occur in low latitudes. • Tropical Rain Forest is most predominant in South America. • South America, Africa, Australia and Antarctica do not have tundra. • Boreal Forest is our ecosystem.

  5. Elevation and Latitude Affect Ecosystems • The changes in ecosystems from the equator to the poles is very similar to the changes in ecosystems from the base of a tropical mountain to the summit.

  9. Ecosystems and Climatic Regions Ecosystems of the world are largely defined by their climax vegetation. Example: tropical rain forest, grasslands, boreal forests, cacti, etc. Climax vegetation is determined by climate. Therefore, ecosystems parallel climate zones.

  10. Ecosystems and Climatic Regions Temperate cold winter gives Boreal Forest Temp. mild winter gives Temp. deciduous Forest Semi-Arid gives Grassland Arid gives Desert Tropical Wet gives Tropical Rain Forest
