What is convergent evolution?
When similar selective forces create similar adaptations in different areas.
How are biomes classified?
Dominant plants. Average temp and precipitation
What classifies a Tundra?
Dwarf, wood shrubs. Few trees Soil is frozen year round. < 0˚ C Low precipitation Low diversity.
What Classifies a boreal forest?
< 5˚ C Low moderate precipitation Low diversity. Huge evergreen forests. Low fertility
What Classifies a temperate rainforest?
4˚-12˚C High percipitation Moderate diversity Evergreens, medium fertility
What Classifies a temperate seasonal forest.
Deciduous trees, no pines. Mildly acidic, fertile. 0˚-20˚C Medium precipitation Moderate diversity
What Classifies a woodland/shrubland?
Grasses & evergreen shrubs Mild fertile Fires Hot dry Low precipitation Moderate diversity.
What Classifies a temperate grassland/cold desert
Nonwood, flowering plant, shrubs. Fertile in grasslands. Fires Cold winters and hot&dry summers Precipitation varies. Low diversity.
What Classifies a tropical rainforest
Canopy of trees. Small trees, shrubs. Soil cycles nutrients quickly, not fertile Warm with little variation High precipitation. Very high diversity
What Classifies a tropical forest/ savanna
Grasses= savanna, Deciduous= trees. Not fertile, cycles quickly Warm with little variation Moderate percipitation High diversity
What Classifies a Subtropical desert
Shrubs cacti, small trees Shallow fertile soil. Hot Low precipitation Moderate diversity
What classifies aquatic biomes
Surface water Flow, depth and salinity
What Classifies a streams and rivers?
Flowing water Riparian zone Allochthonous Autochthonous
What is a riparian zone?
Vegetation surrounding the rivers.
What is allochthonous?
Resources from a different origin
What is an autochthonous
Nutrients from the source of the river.
What Classifies a Ponds and lakes
Non flowing deep Depht zones.
What is the littoral zone?
Edge of lake Emergent vegetation.
What is the limnetic zone?
Has enough sunlight to do photosynthesis.
What is the profundal zone?
Deep whithout enough light to do photosynthesis?
What is the benthic zone
Soil layer.
What is stratification?
Layering in the water.
What is turnover in a lake?
When the layers of stratification change.
What Classifies a Freshwater wetlands?
Non-flowering, emergent vegetation Non-woody
