Transcript of Temperate Deciduous Forest Biome

Temperate Deciduous Forests The temperate deciduous forest biome is characterized by its distinctive seasons (including mild temperatures and trees which lose leaves) and relative diversity of life. Abiotic Factors Additional Information Eastern Cottontail Duck-billed Platypus Location, Location, Location Temperatures and Rainfall Rocks and Soils Yearly Changes Overall Diversity Fauna Flora Biotic Factors Trees: oaks, maples, beeches, sycamores, birches, etc.

Flowers and more: carpet moss, sassafras, redbud, Dutchman's breeches, oxlip, common lime, bluebells, painted trillium, etc. Animal life: fat dormouse, American toad, racoon, squirrel, box turtle, duck-billed platypus, American black bear, long salamander, opossum, black rat snake, magnolia warbler, brown thrasher, cedar waxwing, chipmunks, deer, moose, etc.

N.B. Very few large predators live in this biome, so smaller mammals thrive. This biome, which is generally located in latitudes between 23 degrees north to 38 degrees, goes through four distinct seasons throughout the year: winter, spring, summer, and fall. This cycle lends itself to a multitude of tree species losing their leaves in autumn and growing them again in spring. The summers of the temperate deciduous forests are warmer, averaging out at 70 degrees Farenheit.

Winters are cooler, with temperatures averaging out at a bit below freezing.

Rainfall tends to average 30-60inches yearly. This biome is located primarily in the eastern US, western Europe, and far east Asia. It is noteworthy that the biome is almost always near an ocean or other large body of water within the middle latitudes. Interestingly enough, the more humans live in a temperate deciduous forest biome than any other biome. Much of all temperate deciduous forest biomes have been destroyed to allow for human settlement, agriculture, mining, or logging. Sylvilagus floridanus
This is one of the most common rabbit species in America. They are largely herbivores, but also eat insects from time to time. They can run up to 18 mph, and easily find places to hide. Because of their ubiquitous nature, they are listed as "least concern" by the International Union for the Conservation of Nature. Ornithorhynchus anatinus

This creature lives in the deciduous forest biome of Australia. It is nocturnal and scavenges for food such as shrimp and insects. Its bill isn't like that of a ducks--it's actually an extended muzzle covered in leathery skin. It can swim underwater for a minute and a half! A Virtual Field Trip by Katie Quinn and Olivia Till
AP Environmental Science, A1, 2013 Biodiversity Conditions:
1. Moderate/Abundant precipitation
2. Sunlight
3. Warmth
4. Nutrient Rich Soil
5. Long Growing Season

This biome has a moderate amount of diversity--the abiotic factors allow for relatively average biodiversity. The biome usually possesses several dozen tree species and an array of reptiles and amphibians, but lacks in large mammal species and arboreal species. Its diversity is dwarfed in comparison to Tropical Rainforests which are home to 50% of the Earth’s plants and animals and consist of an estimated 5 to 50 million species. Soil Types:
Alfisols: Dark brown soil, humus based (humus is made up of decayed leaves and organic matter), have two distinct layers--top soil and subsoil, northern US
Ultisols: Brown with red streaks, clay based, more weathered and acidic, poorly aerated, southern US
Rocky soils: Dry and infertile, found in rocks and hills, contributes to quick water drainage, few trees can grow here
Sandy soils: Retain little water, pine trees grow well here, common in northeastern US Human Impact Bibliography
