Description

This function determines the predominance between the diatoms Asterionella formosa and Cyclotella meneghiniana in lake waters as a function of the concentration of limiting nutrients phosphate (PO4) and silicate (SiO2).

p_min_cyc

minimum amount of phosphate needed for Cyclotella to have a positive rate of growth (mg/L) (default = 0.2)

si_min_ast

minimum amount of silicate needed for Asterionella to have a positive rate of growth (mg/L) (default = 1.9)

si_min_cyc

minimum amount of silicate needed for Cyclotella to have a positive rate of growth (mg/L) (default = 0.6)

min_lake_temp

minimum lake water temperature for diatoms to survive (C) (default = 4)

max_lake_temp

maximum lake water temperature for diatoms to survive (C) (default = 28)

p_concentration

phosphate (PO4) concentration (mg/L)

Value

cyc_predominates, ast_predominates, coexistence, no_survival_conditions
