Jan Paschal, former President of AFDW
, reached out to her old friends in the northeast to get some help with contentious mid-term elections in Arkansas.
During the experimental phase, for the control periphyton, we detected the predominance of the organic fraction (AFDW
) over the inorganic (AW).
Measurements of total energy via PDWO generally correlate tightly with AFDW
measurements when the two methods are compared (Jaeckle.
After obtaining a dry weight and an ash weight, the ash-free dry weight (AFDW
), which represents the amount of organic material (biomass) present, was calculated as follows:
Biomass is expressed as g of Ash Free Dry Weight (AFDW
7) indicate that in deeper water, Calliergon underwent shoot etiolation; thus, lower chl-a and AFDW
contents were found there than in annual bands of similar lengths at shallower depths.

The biomass (5), secondary production (P) and turnover rates (P/B) calculated for Tellina lineata (B = 1.391 AFDW
g x [m.sup.-2], P = 2.293 AFDW
g x [m.sup.-2] x [y.sup.-1], P/B = 1.65 [y.sup.-1]) were higher than for Tellina versicolor (B = 0.577 AFDW
g x [m.sup.-2], P = 0.786 AFDW
g x [m.sup.-2] x [y.sup.-1], P/B = 1.36 [y.sup.-1]).
capitatus was 158.03 g [m.sup.-2] (SE = 11.53 g [m.sup.-2]) and AFDW
54.47 g [m.sup.-2] (SE = 5.78 g [m.sup.-2]).
In combination with measures of egg ash-free dry weight (AFDW
), these data yielded estimates of AFDW-specific energy density that were mostly lower than the average weight-specific energy density of carbohydrates.
Shoots, roots, and rhizomes were dried to constant weight at 80[degrees]C, then ashed at 500[degrees]C for 8 hours to determine ash free dry weight (AFDW
Plant material was processed at 60 C to obtain plant dry weight (DW) and ashed at 525 C to obtain ash-free dry weight (AFDW
