|
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
|
|
|
taigo
|
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
|
|
|
littoral
|
shoreline to depth of light penetration
|
|
|
binetic
|
open water that recieves light
|
|
|
profundal
|
portion wher light doesn't reach bottom
|
|
|
benthic
|
interface of water and substrate
|
|
|
Division of water by temp.
|
epilimon and hypoimnion and thermodine
|
|
|
epilimon
|
top portion, mixed by wind and surface action
|
|
|
hypolimnion
|
no moving water occurs apart from internal convective currents
|
|
|
thermodine
|
dinstincee line that separated Epi and Hypo, dramatic change in temp, light and oxygen
|
|
|
types of wetlands
|
swamp, marsh, fen, bog
|
|
|
swamp
|
presence of trees ans slowly moving water
|
|
|
marsh
|
absence of trees but also has slowly moving water
|
|
|
fen
|
canhave trees but is characterized by stagnate water from runoff
|
|
|
bog
|
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
|
|
|
remediation
|
cleaning up site by removing or cleaning contaminants
|
|
|
re-creation
|
attempt to construct a new habitat type
|
