“…For example, the identification of organisms contained in stomach extracts allows the elucidation of wild animal diets, especially when behavioural studies are not feasible (e.g. Krill diets, Passmore et al, 2006; affirmation of polyphagy of the moth Homona mermerodes, Hulcr et al, 2007; Xenoturbella bocki diet, Bourlat et al, 2008). DNA barcoding could also become an efficient tool to clarify host-parasite and symbiotic relationships (Besansky et al, 2003) and in turn give new insights on host spectra, as well as on the geographical distributions of species (host, parasites and/or endangered species).…”

“…In addition, experiments are needed on the extent to which digestion of the target DNA in predator guts reduces detection rates. Given the extreme sensitivity of these methods, stringent efforts are also needed to control cross-contamination during field sampling (Symondson 2002, Passmore et al 2006. In previous papers we described the development of a TaqMan probe for plaice DNA, demonstrated its specificity and described the effects of digestion by crustacean and teleost predators on detection efficiency (Albaina et al 2010, Hunter et al 2012).…”

Mortality during the egg and larval stages is thought to play a major role in de termining year-class strength of many marine fish. Predation of eggs and larvae is normally considered to be a major factor but the full suite of predators responsible has rarely been identified. Potential predators on a patch of plaice Pleuronectes platessa eggs located in the eastern Irish Sea were mapped using acoustics and sampled by trawl and a plankton multi-net. Gut contents of 3373 fish, crustacea and cephalopods sampled in the area were screened using a plaice-specific TaqMan DNA probe. Herring Clupea harengus and sprat Sprattus sprattus dominated trawl catches and showed high positive TaqMan responses (77 and 75% of individuals tested respectively). Locations of clupeid schools also broadly corresponded with the distribution of fish eggs in the plankton. Whiting Merlangius merlangus were also reasonably abundant in trawl hauls and 86% of their stomachs tested positive for plaice DNA. Species showing lower levels of positive TaqMan response included mackerel Scomber scombrus, poor cod Trisopterus minutus, squid Loligo spp., dogfish Scyliorhinus canicula and weever Trachinus vipera. Nonre activity of all negative controls precluded the occurrence of cross-contamination, and positive reactions from demersal species, such as dogfish and weever, may have resulted from secondary predation. No benthic macro-crustaceans tested positive. Samples of planktonic organisms yielded 13% positive TaqMan reactions, mainly from clupeoid or sandeel (Ammodytidae) larvae, but also included some Malacostraca and Amphipoda. Use of the molecular approach allowed rapid screening of a large number of potential predators of plaice eggs, and the results provide a more holistic description of the predator community than has previously been achieved.

“…It may also be used for biodiversity assessment in groups where taxonomic information is incomplete or difficult to use (Blaxter et al 2005;Passmore et al 2006;Frezal & Leblois 2008) or for large inventories (Telfer et al 2015). …”

D N A L i b r a r y o f L i f e , r e s e a r c h a r t i c l eurn:lsid:zoobank.org:pub:41D67A95-553F-4A8E-BC50-33BAA1FA5B0A Abstract. The characters used in taxonomy to describe new species cannot always be used to identify species in population surveys involving large samples. We used DNA barcoding to validate the taxonomic status of the morphospecies used in an ecological study involving 11 000 individual African drosophilids which had been determined without dissection. Some taxonomic information had been lost by not discriminating between rare species or by mistakenly splitting a morphologically variable species into two groups. However, the original ecological dataset provided a reliable picture of species diversity and the conclusions based on the original dataset are still supported by the molecular data.
