1. Introduction

nature of course

assignments (simulations, 2 short papers, 1 final paper)

2. Ecophysiology of phytoplankton (the story)

small algae

float around in the water

photosynthesize

take up nutrients

metabolize these and allocate optimally

to support growth and survive

while competing with other species

persist through time in the community

patterns of succession

 

3. Match to the environment

new synthesis

 

4. Importance of Phytoplankton

a. base of open water food chains

b. drive biogeochemical cycles

c. eutrophication can degrade water quality for human uses

d. blooms of toxic algae can have direct effect on humans

e. possible fuel or synthetic stock
