Trophic relationships in a deep Mediterranean cold-water coral bank (Santa Maria di Leuca, Ionian Sea) (2009, background): “Some authors found no significant effect (Sarakinos et al. 2002), whereas other studies evidenced significant δ15N shifts (Bosley & Wainright 1999, Edwards et al. 2002).”
Using stable isotopes and quantitative community characteristics to determine a local hydrothermal vent food web (2007, background): “In fish tissues, Edwards et al. (2002) found a systematic decrease in δ13C (ca. 1.1‰) and an increase in δ15N (ca. 0.5‰) due to formalin preservation, but similar consistent trends were not apparent here.”
Stable isotopes and trace elements as indicators of diet and habitat use in cetaceans: predicting errors related to preservation, lipid extraction, and lipid normalization (2010, background): “…based on studies on long-term preservation in ethanol or formalin, we suspect changes in isotope ratios after 1 yr storage to be insignificant (Edwards et al. 2002, Sarakinos et al. 2002, Syväranta et al. 2008, Carabel et al. 2009) and correction curves presented here to be valid beyond 1 yr…”
Stable isotope addition reveals dietary importance of phytoplankton and microphytobenthos to saltmarsh infauna (2008, background): “Edwards et al. (2002) and Levin et al. (2006) both reported that short-term fixation in formalin has little effect on δ15N and δ13C values.”
Using stable isotope biogeochemistry to study marine mammal ecology (2010, background): “…of this alteration varied widely among methods, but for some, such as ethanol or formalin, the effects appear to be consistent and correctable (Edwards et al. 2002) and previous studies (Todd et al. 1997) have shown that careful preparation using either sonication or Soxhelet extraction can…”
