|
replicates
|
separate (independent) units of study that are treated identicaly by ecologists, in order to assess variability that arises from factors we didn't manipulate
|
|
|
controls
|
units that did not experience the focal manipulation. they provide a baseline for comparison, an understanding of how organisms or systems will change over time or space, independent of experimental treatments
|
|
|
statistsics
|
tools that help us distinguish signal from noise, eg. test whether differeneces betweeen treaments (eg. control vs. experimental) are greater than differeneces within treatments
|
|
|
reductionist approach
|
seeking mechanisms, causal process (eg. catipillars feed and grow faster on nitrogen rich leaves)
|
|
|
holistic approach
|
determining boundaries of the system (all that must be included) necessary for understanding and predicting outcomes of ecological interactions in the real world
|
|
|
zoom lens ecology
|
focus in for mechanism, zoom out for context and consequences
|
|
|
Deductions
|
predicting specific outcomes from general models
|
|
|
Induction
|
generalizing from specific observations to more general models
|
|
|
adiabatic cooling
|
rising air experiences lower atmospheric pressure, expands in volumes, losing temperature. If it cools below dew point, air will lose its moisture (as clouds, or precipitation)
|
|
|
dew point
|
temperature to which the air would have cool (at constant pressure and constant water vapor content) in order to reach saturation, at which the air is holding the maximum possiblem amount of water vapor possible at the existing temperature and pressure
|
|
|
thermocline
|
stratum of rapid temperature change. Can separate oxygenated from hypoxic habitat.
|
|
|
eutrophic
|
nutrient rich, likely to produce noxious or harmful algal blooms (cyanobacteria, toxic dinoflagellates)
|
|
|
mesotrophic
|
intermediate nutrient concentrations
|
|
|
oligotrophic
|
low nutrient concentrations, very clear water (good water quality for humans and fish)
|
|
|
estuary
|
where the rivers empty into oceans, fresh water meets salt water: tidal prisms with heavier salty water underneath
|
