An Overview of the Six Major Terrestrial Biomes

Biome: Large complexes of communities characterized by a distinctive vegetation type and climate.

Deciduous Forest warm summers cool winters yearly precipitation: 75-250cm deciduous trees lose their leaves every year

Inhabitants Deer raccoons bears oaks maples hickories various species of small birds

Location: Europe North-eastern United States Eastern Canada

Coniferous Forests Short growing season cold winters yearly precipitation: 20-60cm primary source of the world’s lumber

Inhabitants: Elk Moose Rabbits Needle-leaves evergreens

Location: Northern Asia Northern North America

Rain Forest climate is hot and wet little temperature variation abundant moisture yearly precipitation: 250cm contains more species than any other biome forests and their species are being destroyed at an alarming rate

Inhabitants: Many tall trees variety of insects jaguars armadillos snakes birds monkeys

Location: Tropical regions of South America Central America Asia Africa Australia

Deserts dry sparse vegetation scattered grasses yearly precipitation: 20cm inhabitants must conserve water

Inhabitants: Kangaroo rats Camels cactus: have spines; deep roots; and a waxy covering to prevent water loss

Location: Parts of Africa Asia Australia North America

Savannas Open widely spaced trees seasonal rainfall yearly precipitation: 90-150cm conversion to agriculture threatens inhabitants

Inhabitants: Lions Rhinoceroses Elephants Giraffes Gazelles Rabbits Grasses

Location: Parts of Africa South America Australia

Tundra Open wind-swept dry ground is always frozen yearly precipitation: 25cm covers one-fifth of the Earth’s land surface

Inhabitants: Caribou Lemmings Wolves Mountain lions Foxes Mosses and lichens

Location: Far Northern Asia Northern North America

Major Terrestrial Biomes Tropical rainforest Temperate rainforest Temperate deciduous forest Taiga (boreal forest) Tundra Desert Temperate grassland Savannah Chaparral/Steppe Urban

Cyanea capillata

Branching Corals Doming Corals

Sea Pen Soft Corals Sea Pansy

Gorgonians (Sea Whips)

Pleurobrachia Beroe

Major Aquatic Biomes Marine Open ocean Antarctic ocean (edge of the ice) Estuary Coral Reef Barrier Island Shallow ocean/bay Mangrove forests Freshwater River Lake Pond Wetlands (Swamps, marshes, etc.)
