Seasonal Patterns and Cyanobacterial Dominance

1. competition can lead to succession

sequential depletion

light utilization characteristics (Kirk)

CSR framework

 

 

2. Descriptive model of the seasonal pattern

PEG model

includes growth and grazing terms

heuristic value for developing new questions

 

3. CSR and successional trajectories

fig 5.21

 

4. general factors that can contribute to cyanobacterial dominance

List of factors

 

is this cause and effect or interaction of these resources and conditions

determines the study approach

5. shallow lake and stabilizing factors for each basin

multiple factors in shallow eutrophic lakes
