JonahWater delivers insight into aquatic ecosytems, both freshwater and marine
Our JonahWater services answer questions about species in aquatic ecosystems.
We quantify aquatic assemblages by sequencing aquatic environmental DNA.
Using both quantitative PCR and Metabarcoding, we quantify phytoplankton, macroinvertebrates, fish, and other organisms in the water.
JonahWater gives you the capacity to quantify:
- Phytoplankton such as cyanobacteria, diatoms, and green algae
- Macroinvertebrates such as mayflies, chironomids, and mussels
- Vertebrates such as fish, mammals, reptiles, and amphibians

For quantifying organisms in water, choose from qPCR or metabarcoding
Single or Few Species
To quantify single species or a small number of species (<5), we recommend qPCR. qPCR works best for small numbers of species when you want to quantify the absolute abundance of DNA in water. False negative rates are lowest here. We also use qPCR for source tracking of E. coli in water.
To quantify the relative abundance of species in assemblages, we recommend metabarcoding. Metabarcoding quantifies large numbers of species within a given taxonomic group (phytoplankton, insects, fish, vertebrates, etc.). Metabarcoding is best when relative abundance is desired.
