Column | Name | Description |
---|---|---|
RA | Relative Abundance | number of cells (density of cells per square centimeter) in a sample / total abundance of all taxa |
RB | Relative Biovolume | Volume of a taxon’s cells in a sample / volume of all algae cells in a sample |
Oxy | van Dam Oxygen tolerance | 1=100% DO saturation, 2=>75% DO saturation, 3=>50% DO saturation, 4=>30% DO saturation, 5=<30% DO saturation |
Sap | van Dam Saprobic value | Saprobic values relate to the amount of organic pollution, biological oxygen demand, and DO concentrations. Values range from 1 (intolerant of organic pollution) to 5 (highly tolerant of organic pollution) |
Sal | van Dam Salinity value | 1=freshwater (<100 mg/L chloride) , 2=fresh-brackish (<500 mg/L), 3=brackish-freshwater (500-1000 mg/L), 4=brackish (1000-5000 mg/L) |
Tr | van Dam Trophic value | 1=oligotraphentic, 2=oligo-mesotraphentic, 3=mesotraphentic, 4=meso-eutraphentic, 5=eutraphentic, 6=hypereutraphentic, 7=indifferent to trophic state |
Mot | Motility of Diatoms | Motility (capability of movement in water or on substrates) based on genus (Wang et al. 2005): N= not motile, M = motile , H = highly motile, V=variable within genus |
GF | Growth Forms | E= erect, P=prostrate, S=stalked, U=unattached, V=variable (based on communication with R. Jan Stevenson) |
Tol | Tolerance value | Tolerance to a combination of watershed disturbance, conductivity, and nutrient enrichment (based on Maine data). Value range from 1=most senstive to 100=most tolerant. |
TN | TN value | Preference for total nitrogen (TN) based on Maine data. Values range from 1=low TN concentrations to 100=high TN concentrations. |
TP | TP value | Preference for total phosphorus (TP) based on Maine data. Values range from 1=low TP concentrations to 100=high TP concentrations. |
