Gut content and food web analyses

IMG 9468 res

Metabarcoding of the DNA samples obtained from the stomach is now a common tool to reconstruct food webs of species. The advantages of this approach are that it can be applied even to a partially digested material, that no longer cannot be identified by morphology and that multiple prey species, including rare ones, can be identified either from animal gut samples. Our analytical protocols only require a small subsample from guts or droppings to detect even traces of prey species an animal.

We offer targeted DNA assays to scan for the presence of specific species across a multitude of potential predator species, e.g. to identify which species feed on the invasive round goby Neogobius melanostomus. These assays can then be complemented with food web analysis based on DNA metabarcoding revealing the community present in a gut sample, e.g. to identify the species consumed by the invasive round goby Neogobius melanostomus.

In the Publications section, you find an updated list of Reports as well as Academic publications showing how our gut contents assays can be used for food web analysis.
