Reductionist
method of understanding ecological patterns and processces using mechanisms and causal processes. Ie. cat. grow faster on N rich leaves
Holistic
determine boundaries of the system needed to understand the outcome of ecological interactions in the real world.
zoom lens ecology
focus in for mech, zoom out for context.
ecological forecasting
acknowledge uncertainty and context dependency.
tools for dealing with ecological variablity:
1-replicates
2-controls
3-stats
Replicates
separate, indpt units of study that are treated identically by ecologists, in order to assess variablity that arises from factors not manipulated.
controls
provide baseline for comparison
Macan's Filter
a species can be excluded from a certain habitat by:
1-dispersal (not arrived, cant't persist)
2-Behavior (avoids habitat, can't persist)
3-abiotic factors
4-biotic interactions
propagule
dispersing unit capable of establishing a new population
Condition
abiotic environmental factor that varies in space and time and affects the performance of the organism.
Resource
all things consumed by organisms
Adiabatic Cooling
rising air expands in volume, losing temp. If it cools below dew point, air will precipitate.
Dew Point
temp at which air is saturated, any lower and there will be precipitation.
Global Climate Patterns
wet tropics at equator
deserts at 30 N &S
Temperate rainforests @ 60 N&S
antarctic and arctic deserts
Coriolis Effect
equator is traveling faster than the rest of the earth, as you go N>>obj veers right and south>>>obj veers left
Eutrophic
river, lake, estuary. nutrient rich>>can produce toxic algal blooms
Mesotrophic
intermediate nutrient concentrations
Oligotrophic
low quantity of nutrient concentrations. very clear water, good for people.
parts of river
1-headwater
2-meandering middle reaches
3-lowland flood plains
Headwater
woody debris, forest cover
Meandering Middle reaches
clean gravel beds, hyporheic habitat, undercut rooted bank veg, off river hab,
Lowland floodplain river
marshes or forests, off channel water bodies
hyporheic
The area below the streambed where water percolates through spaces between the rocks and cobbles (Interstitial Space).
estuary
where rivers empty into oceans
tidal prism
wedge of fresh water overlies denser salt water
eurysaline
wide tolerance to salt
osmoregulation
ability to regulate salinity
plankton
passive drifters
nekton
active swimmers
neritic
nearshore subtidal
benthic
life on the substrate of sea, river lake.
Pelagic
offshore, beyond continental shelf
