Molecular detection of algal prey in copepod guts and fecal pellets (2003, methodology): “…and copepods for DNA analysis were immediately frozen at –80°C. Estimation of copepod gut chlorophyll—Copepods reserved for gut pigment analyses were extracted for 12 h in 90% acetone at 4°C and analyzed on a Turner Designs Model 10-AU Fluorometer as previously described (Nejstgaard et al. 1995).”
The diet of deepwater sharks and the benefits of using DNA identification of prey (2010, background): “…widely used in identification studies including fish products (Bartlett and Davidson, 1992; Smith et al., 2008), and allow the identification of poorly preserved and small tissue samples, but are a relatively new approach for fish prey identification (Rosel and Kocher, 2002, Smith et al., 2005).”
Quantitative PCR to estimate copepod feeding (2008, unknown): “bacterivory by heterotrophic Xagellates (ChristoVersen et al. 1997), predation by euphausiids on early life stages of anchovy (Theilacker et al. 1993), and identiWcation of zooplankton prey in the guts of paralarval squid (Venter et al. 1999) and of cod larvae in Wsh stomachs ( Rosel and Kocher 2002”
