Improve Your Understanding of Water

JonahWater delivers insight into aquatic ecosystems

Our JonahWater services answer questions about species in aquatic ecosystems

We quantify aquatic assemblages by sequencing aquatic environmental DNA .

Using both Quantitative PCR and Next Generation Sequencing, we quantify phytoplankton, macroinvertebrates, fish, and other vertebrates in 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

 

River miles sampled so far

Sequencing of environmental DNA has the potential to transform our understanding of aquatic ecosystems. Using NGS and qPCR gives managers better data cheaper and faster than traditional techniques. All from 250 milliliters of water…

Our NGS Process

1. Collect

Collect water and filter through syringe.

Send to Jonah Ventures Lab.

2. Extract

We extract DNA from sample.

3. Amplify

Specific regions of DNA are amplified into ampliconsusing pairs of primers.

Each primer pair is specific to a broad taxonomic group.

4. Index

Short, unique segments of DNA are attached to each amplicon to index from which sample it originated.

5. Pool

Indexed amplicons from multiple samples are pooled together

6. Sequence

Amplicons are sequenced

7. Bioinformatics

Data from sequencer is bioinformatically processed to identify groups of similar sequences called OTUs.

8. Identify

OTUs are matched against a reference database to identify the species each OTU represents.

Example NGS Data

NGS excels at quantifying the relative abundance of species in an assemblage. Shown here are data on the proportions of different phytoplankton species from the length of the Potomac River. For each sample, approximately 100 mL of water were filtered. After collecting we then sequenced the filtered DNA using primers specific to all phytoplankton.Top four taxa are shown.

The phytoplankton assemblage was dominated by diatoms (Bacillariophyta), but different taxa dominated different regions. We also quantified abundances of cyanobacteria, chlorophytes, and eustigmatophyte. The patterns observed in the Potomac showed clear patterns of the effects of river size and eutrophication.

Whether it is for quantifying changes in assemblages over time, detecting invasive species, or comparing assemblages across sites, we can reconstruct the abundances of aquatic organisms using our JonahWater services.

Our qPCR Process

1. Collect

Collect water and filter through syringe.

Send to Jonah Ventures Lab.

2. Extract

We extract DNA from sample.

3. qPCR

Specific regions of DNA are amplified into amplicons using pairs of primers.

Each primer pair is specific to a taxonomic group. Probes then fluoresce if there are matches to individual species.

4. Cq Value

The amount of fluorescence for each cycle is quantified and the cycles repeated to generate a fluorescence curve.

The Cq value is the number of cycles it takes to detect fluorescence.

5. Calibrate

A calibration curve is used to relate the number of cycles it takes before fluorescence is detected (Cq) and the abundance of specific DNA sequences.

6. Calculate

Together, the Cq values and the calibration curves determine for each sample if the DNA of a species is present in the sample and the number of copies of DNA per mL water.
