Difference of lacustrine and marine
lacustrine = lake, unconsolidated bottom, rock bottom. Stagnant water, fresh water, fringe, animals and plants.
marine = salinity, waves, tidal, reef, rock, shore, plants and animals
hydroperiod of fen vs riverine
fen = groundwater = gradual so not much movement
riverine = fluctuate gets most water from surface water
bog or fen more acidic
bog = surface water and ombotrophic - more acidic
fen = ground water, minerotrophic
what characterizes a swamp
trees
what regime influenced by oceanic tides and saline
estuarian/marine
water not tidal, or if tidal not saline
lacustrine, palustrine, riverine
difference between ct def. and govern. def of wetland
ct's is based on soil characteristics. govern. is soil, hydrophytic vegetation and hydrology. if we used govern. half of our wetlands wouldnt be considered wetlands. (currently 17%)
major causes of wetland loss
urban, agriculture, silviculture, rural
wetland plant adaptations
shallow roots, adventitious roots, pressurized gas flow, decreased water uptake, timing of seed production, buoyant seeds, resistant roots and seeds, excrete salt, dont take up salt
freshwater wetland plants
phragmites, typha, juncus, cyperus, bulrush
anoxia
adaptations of animals for more nutrients and gas exchange
adaptations of plants to take up different nutrients also
wetland animal adaptations
organs or gas exchange, improving oxygen conditions, better circulation, behavioral changes, secrete salts, exoskeletons
turgor
absorb water until pressure of cell is balanced by resistance of cell membranes and walls
shallow marsh/fen
soil waterlogged during growing season; often covered with 15cm or more of water
deep marsh/fen
soil covered with 15cm to 1m of water
shrub swamp
soil waterlogged; often covered with 15cm or more of water
wooded swamp
soil waterlogged; often covered with 30cm of water; along sluggish streams, flat uplands, shallow lake basins
evapotranspiration
evaporation from surface water but also from the soil and plants
ground water flow
in hydrologic cycle show the direction of flow either in or out or both
subtidal
always flooded
intertidal
exposed and flooded at high tide
pem
palustrian emergent
pfo
palustrian forested
pss
palustrian scrub-shrub
ab
aquatic bed
ow
open water
ub
unconsolidated bottom
us
unconsolidated shore
fac plants
facultative plants - similar chance in wetland and upland (33%-66%) ex. locust, smilax
facu plants
facultative upland plants - sometimes in wetlands (33%), more often in uplands (greater than 67%) ex. red oak
water sources
precipitation, tides, ground water, evapotranspiration, surface water,
hydrogeomorphic classifications of wetlands
depressional, fringe (tidal or lacustrine), slope, rivine, flats (peatlands or fresh)
bogs water source
precipitation, about 25% could be ground water
fens water source
ground water, about 25% could be surface flow
riverine water source
surface flow and about 25% could be precipitation
water movement 3 choices of directions
verticle, unidirectional, bidirectional
what to think about when designing a habitat
other wetlands in proximity, keep diversity, the type, size, length of shoreline, islands, water source, variety of food sources,
marsh vs swamp
swamp - trees, shrubs, organic or mineral sediments, oxygen and minerals abundant, productivity high
marsh - emergent vegetation (cattails), grasses, mineral soil substrate
bog vs fen
bog - peatland with high water table, mosses, w/ or w/o trees, acidic, ombotrophic, some raised
fen - peatland with high water table, grasses, sedge's, shrubs, reeds, few trees, minerotrophic (not acidic)
three things required for wetland
hydroponic plants, hydrophilic plants, soil of certain kind
what happens if you add water to nitrogen cycle
ammonification
