DNA usually degrades relatively quickly in the open water. However, DNA submerged in sediments of ponds, rivers or seabeds can remain stable for much longer periods. Thus, marine and freshwater sediments can preserve records of past biological communities and indicate the presence of departed species and thereby provide essential insights for conservation and reintroduction efforts.
We offer sampling and analysis of sediment cores in both marine and freshwater ecosystems to reconstruct target species distribution and abundance as well as community composition through time.
In the Publications section, you find an updated list of Reports as well as Academic publications showing how our services can be used for sediment core analysis and historical inference of species abundance.
