-
what is the nutrients like in lakes and ponds?
seasonal variation, variation by zone
-
Compare the water depth of lakes and ponds
lake varies but generally deep compared to ponds
-
light availablility in lakes and ponds?
only in photic zone
-
What isthe water movement in lake and ponds?
- Process: seasonal turnover
- factors: wind, temperature
-
What are the different kinds of wetlands?
- bog vegetation: specialized;
- marsh: non-woody
- swamp: shrubs and trees
-
Describe the nutrients in the wetlands.
- low nutrient and low oxgen in bogs and it is acidic
- nutrient and oxgyen rich in marshes and swamps
-
water depth in wetlands?
little standing water in bog; shallow in marsh and swamps
-
light availibility in wetlands?
N/A for bogs, penetrates to bottom for marshes, pentrates to bottom where canopy is permitted for swamps
-
what is the water movement like for the wetlands?
bogs are stagnant, no movement; slow moving and unidirectional for marshes; slow moving for swamps
-
what is the nutrients like in estuaries?
high nutrients, high oxgen
-
what is the water depth like in estuaries?
generally shallow but varies with flow
-
light availiability in estuaries, streams and rivers?
penetrates to bottom
-
what is the water movement of estuaries:
moves in two directions, tidal changes, river/stream flow
-
what are the nutrient level like in streams and rivers?
depends on flow rate, fast moving: low nutrients, low oxgyen; slow moving: high nutrients, high oxgyen
-
what is the water depth of streams and rivers?
shallow
-
what is the water movement of streams and rivers?
varies, unidirectional, change in elevation, temperature gradient from start to finish.
-
nutrient level in oceans
varies depending on zone
-
water depth and light availability in ocean
deep, only in photic zone
-
water movement in ocean
depends on location, tidal upwelling, temperature, water currents, air currents
-
What is the AT and TV for tropical wet forests?
high average temp, very low variation
-
average precipitation and precipiation variation in wet forests?
very high, high
-
diveristy in wet forests?
very diverse, exploit many different niches
-
desert?
- avg temp high, moderate vartiation
- avg p, very low, low variation
-
acitivity in desert?
30 north and south, a lot of vartaion in acitivty, trigger is precipitation, takes advantage of temporal nature. intense response to rain
-
Temperate grasslands?
- Avg temp: moderate, moderate temp variation
- low p, moderate p variation
-
Can trees be successful in grasslands? why?
too dry for trees to be successful; trees can't be estabished, becuse carbon needs to be stored below graound, trees dont' do that in time of fire
-
temperate forests?
moderate avg temp and temp variation, modeate avg p and low p variation
-
productivity of temperate forests?
shift of grass to trees of lower productivity than tropical forests
-
boreal forests?
low avg temp, very high temp varation; low avg p and p variation
-
acitvty of boreal forests? location?
subartic lands south of artic circle; low productivity, slow and steady process of growth, consistent level of acitivity
-
Tundra?
very low temp, high temp variarion, very low p, low p variation
-
tundra acitivty?
not covered with ice, trees not in this biome, low line taking advantage of the microclimate as you get lower to the gorund, average very low temperatures
