From: Preservation effects on wet weight, dry weight, and ash-free dry weight biomass estimates of four common estuarine macro-invertebrates: no difference between ethanol and formalin

Fig. 2

The DW of samples preserved in 70% ethanol (open circles) and 4% formalin (filled circles) for 10, 21, or 90 days in percent of DW of unpreserved samples in four macrofauna species. The DW of unpreserved samples (day 0, open triangles). Error bars represent 95% CI. A small offset (±1 day) has been applied between treatments with ethanol and formalin to avoid graphic overlap
