Aquatic Stream Ecology 2

Winkler Titration
Measuring the amount of dissolved oxygen
Upwelling Zones
When water comes up onto the coast and brings nutrients
Tolerance Curves
Organisms perform best when a condition is in its optimal range (pH, dissolved oxygen, temperature)
thylakoid
Located inside the chloroplast
Thermocline
Point where water temperature changes rapidly
Succession
The changing of an ecosystem over time
Stroma
The empty space inside the chloroplast
Secchi Disk
Can determine the penetration of light and the wavelength
Sea WiFs
Sea viewing wide field of view sensor
RUBISCO & PEPck
Enzyme that fixes carbon in light independent reaction
Residence Time of Ions
Total Mass/Rate of Supply
Refractometer
Measures refraction of light
Picoplankton
Plankton measuring between .2-2 micro meters. Microplankton are 100x larger Nanoplankton are 10x larger
Phycobilin
A pigment in red algae and cyanobacteria
Pelagic
Floating
