Crash Course
FACTORS AFFECTING BIOMES
▸ Temperature and precipitation- why?
▸ Boundaries vary- ecotone
▸ Vegetation type used as an indicator
TROPICAL RAINFOREST▸ High precipitation;
always warm
▸ Equatorial
▸ Most biodiversity
▸ Human impacts?
SAVANNA (TROPICAL GRASSLANDS)▸ Seasonal (dry and
wet); always warm
▸ Equatorial
▸ Fire-adapted plants; drought tolerant; many herbivores
▸ Human impacts?
DESERT▸ Very little precipitation
▸ Variable temperatures; cold at night (why?)
▸ Sparse vegetation; drought tolerant
▸ Animal adaptations
TEMPERATE GRASSLAND▸ Seasonal precipitation
(dry/wet)
▸ Seasonal temperatures (cold/hot)
▸ Fire-adapted grasses; herbivores; fertile soil
▸ Human impacts?
TEMPERATE DECIDUOUS FOREST▸ Summer rain and winter
snow
▸ Seasonal; moderate warm/cold
▸ Many mammals; fertile soil
▸ Deciduous?
CONIFEROUS FOREST/TAIGA/BOREAL▸ High latitude
▸ Adequate to try precipitation
▸ Cool year round
▸ Conifers
TUNDRA▸ Highest latitudes
▸ Dry; cold
▸ Permafrost
▸ Adaptations
▸ Human Impact
CHAPPARAL (MEDITERRANEAN)▸ Mild winters
▸ Hot, dry summers
▸ Shrub land
▸ Human impact
