Biomes & Such

Also called Arctic Tundra. Cold, boggy plains existing in the extreme northern latitudes. Long, harsh winters and short summers. Layer of permafrost, permanently frozen ground.

Taiga. Dominated by conifers, a huge evergreen forest biome that stretches across northern portions of north america and eurasia. Worlds largest biome, with wolves, bears, moose, and caribou.

Coniferous temperate rain forest is one of the richest wood produces in the world and supplies us with lumber. Also rich in epiphytic vegetation, such as mosses, lichens, and ferns.

Summers are hot, winters are cold. Broadleaf evergreens, saplings, and shrubs. Hardwoods, such as oak, hickory, etc. (high school biome?)

Moist temperate grasslands, also known as tallgrass prairies, occur in Iowa, Nebraska, and other midwestern states. Few trees grow, except near rivers and strems.

Thicket of evergreen shrubs and small trees. Mediterranean climates, with soils that are thin and relatively infertile. Native plants are adapted to the fires since they are so frequent.

Deserts are dry areas in temperate (cold deserts) and subtropical or tropical regions (warm deserts). Desert soils are low in organic material but often high in mineral content, such as salts sodium chloride and calcium carbonate.

Tropical grassland with scattered trees. Savannas are found in warm, tropical areas of relatively low rainfall or seasonal rainfall with prolonged dry periods.

India, Brazil, Thailand, and Mexico. Occurs in regions with a wet season and a dry season. During the dry season, many tropical trees shed their leaves and become dormant. Integrate with Savanna on dry edges, and Tropical Rain Forest on wet edges.

When the temperature is warm throughout the year and precipitation occurs almost daily. Found near the equator in Central and South America, Africa, and Southeast Asia. Most trees are evergreen flowering plants. Usually not dense at ground level, except near riverbanks.

Carbon Dioxide (CO2) and certain other trace gases, including methane (CH4), surface ozone (O3), nitrous oxide (N2O), and chlorofluorocarbons (CFCs), are accumulating in the atmosphere as a result of human activities.

The current warming trend in Earth's climate

An enzyme that cuts double-stranded or single stranded DNA at specific recognition nucleotide sequences known as restriction sites.

VECTOR: Must be present to transfer DNA from one organism into another organism (plasmids or viruses)

LYGASE: the glue needed to glue cut-sequences into vector

• An organism whose genetic material has been altered using genetic engineering techniques. Generally known as recombinant DNA technology, uses DNA molecules from different sources, which are combined into one molecule to create a new set of genes. DNA is then transferred into an organism.
• Resistance to pests so plants don't need pesticides.
• Resistance to drought, viruses, etc.

The interacting system that encompasses a community and it's nonliving physical environment.

Living and Nonliving things

A subfield in ecology dealing with the relationship of organisms with one another and with their environmenton a global scale.
