Transcript of Biomes

Deserts
Temperate Grasslands
Temperate Broadleaf Forests
Tundra
A chaparral is a region of dense, spiny shrubs, with tough evergreen leaves. The coastal areas result in cool ocean currents that produce rainy long winters, and hot long dry summers.
Deserts are the driest of all terrestrial biomes, some deserts can be very hot, with day time soil temperature above 60 degrees! However some can be cold and have temperatures below -30 degrees celcious.
Biomes

Temperate grasslands are mostly treeless, except along rivers and streams: and are usually found around areas with cold winters.

The tundra is characterized by long, bitter-cold winters. The word itself derives from the Russian meaning "marshy plain". The climate here is extremely cold, with little light for long periods of time. The arctic tundra is characterized by permafrost, or continuously frozen soil.
Savannas

What is a biome?
A biome is a large naturally occurring community of flora and fauna occupying a major habitat. Biomes cover large areas of the Earth's surface with animals and plants that have adapted to its environment and climate.
There are two major different types, these are
freshwater and terrestrial biomes
.
Aquatic VS. Terrestrial
Aquatic biomes
can be broken down into two basic regions, freshwater and marine.
Freshwater biomes
include
lakes, ponds, rivers, streams, and wetlands
.
Freshwater biomes are defined by having a low salt concentration- about 1%

Marine

biomes
cover about three-fourths of the Earth’s surface and include
oceans, coral reefs, and estuaries.

Terrestrial biomes
are distinguished primarily by their predominant vegetation, and are mainly determined by temperature, climate and rainfall. There are 8 major types of terrestrial biomes: these include
tropical forests, savannas, deserts, grasslands, temperate forests, coniferous forests, tundras, and chaparrals.

Tropical forests occur in equatorial areas where the temperature is warm and/or humid.

Rainfall
: Quite variable but usually 200-400 com per year.
Tropical Forests
Fauna
: (tree-dwellers) Monkeys, birds, insects, snakes, bats, and frogs.

Flora
- Woody vines known as lianas, and epiphytes (plants that grow on plants).

Savannas are dominated by grasses and scattered trees. They are also warm year round.

Rainfall
: 30-50 cm per year

Fauna
:
Herbivores
- Ants and Termites.
Burrowing animals
- Mice, moles, gophers, snakes, ground squirrels, worms, and numerous arthropods.
some savannas may be home to giraffes, zebras, antelopes, lions, cheetahs, and kangaroos.

These forests grow throughout mid-latitude regions where there is enough moisture for the growth of the large trees. Temperatures range from very cold winters to hot summers (-30 degrees celcious to +30 degrees celcious).
Fauna:

mice, shrews, ground squirrels, birds, bobcats, foxes, black bears, and mountain lions.
Rainfall:
30-60 in. per year
Flora:
Oak, hickory,birch, beech, and maple trees
Coniferous Forests/Taiga

The taiga is characterized by long cold winters and short, wet winters that are sometimes warm.
