What is a biome?
area with similar climate, tepography and soil conditions
What was a biome named for?
the dominant vegetation that grows there
what are the qualities of a biome?
rainfall and ranged of temps.
Define desert.
area with extremely low rainfall, falls 30 degrees latitude, temp. fluctuates
define grasslands
prairies and savannas- fixed seasons in terms of temp. and rainfall, very productive soils. Few trees because of moderate rainfall and role of fire and animals
What animals used to be seen often in prairies?
buffalo and passenger pigeons
define tundra.
alpine and artic- alpine and artic located in high altitudes- short growing season and harsh winters. Lots of water but in the form of ice and snow.
Define Alpine
exposed to higher level of UV radiation and less access to water than artic b/c of tepograhpy and runoff
Conifer forest
boreal, taiga, and pacific coasts- sandy soils from glaciers, with little water retention, needles, short growing season, fire play important role, mixed hardwoods
Pacific coast
redwoods, foiund in more mild temp. and abundant rainfall
located at northern edge of conifer range befroe transition in tundra
Tropical moist forests
ample rainfal and uniform temp. biologically rich, thin acidic soil and very nutrient poor, quick turnover time
Auguatic ecosystems-
varied in climate, soil, deals with everything occuring upstream, water clarity and depth affect water penetration, changes in temp.
Habitat stratification
division by light pentration
types of habitat stratification
littoral, binetic, profundal, benthic
shoreline to depth of light penetration
open water that recieves light
portion wher light doesn't reach bottom
interface of water and substrate
Division of water by temp.
epilimon and hypoimnion and thermodine
top portion, mixed by wind and surface action
no moving water occurs apart from internal convective currents
dinstincee line that separated Epi and Hypo, dramatic change in temp, light and oxygen
types of wetlands
swamp, marsh, fen, bog
presence of trees ans slowly moving water
absence of trees but also has slowly moving water
canhave trees but is characterized by stagnate water from runoff
can have trees, but has stagnate water from rainfall
what do wetlands do to land?
detoxify substances and replenish underground aquifiers- great place for birds to migrate
what is restortion ecology?
any science concerned with repair for reconstruction of damaged landscpaes regarless of human or natural causes
what is restoration?
bring back to former state
cleaning up site by removing or cleaning contaminants
attempt to construct a new habitat type
