Study Notes

Tropical Rainforest

Warm and wet year-round; thin, nutrient-poor soils.
Biotic features include large-leaved plants and buttress tree roots; animals remain active throughout the year.

Tropical Dry Forest

Consistently warm with alternating wet and dry seasons; rich soils.
Dominated by deciduous plants with waxy leaves; many animals estivate or migrate.

Savanna

Warm climate with seasonal rainfall; compact soils; frequent lightning-induced fires.
Vegetation consists of waxy-leaved plants with seasonal leaf loss; many animals migrate or become dormant during the dry season.

Desert

Characterized by low precipitation, variable temperatures, and soils deficient in organic material.
Small-leaved plants thrive; many animals are nocturnal and obtain moisture from their food.

Temperate Grassland

Features warm summers and cold winters with moderate precipitation; fertile soils; and occasional fires.
Plants adapted to grazing and fires; small animals utilize camouflage and burrowing for protection.

Temperate Woodland and Shrubland

Warm, dry summers and cool, moist winters; soils are nutrient-poor; periodic fires occur.
Vegetation consists of plants adapted to drought and fire; animal species generally act as browsers.

Temperate Forest

Cold winters and warm summers with year-round precipitation; fertile soils are prevalent.
Includes deciduous trees; some animals hibernate while others migrate in winter.

Northwestern Coniferous Forest

Mild temperatures with abundant precipitation in fall, winter, and spring; cool, dry summers; rocky, acidic soil.
Features dense plant growth with tall trees; diverse diets among animal species.

Boreal Forest

Long, cold winters and mild summers with moderate precipitation; acidic, nutrient-poor soil.
Dark-green coniferous trees are common; many animals possess extra insulation or migrate during winter.

Tundra

Strong winds, low precipitation, short soggy summers, and long, cold, dark winters with permafrost.
Small plants grow close to the ground; many animals migrate in winter or have adaptations to conserve heat.
