Endangered Species Testing

Environmental DNA (eDNA) refers to the genetic material shed by organisms into their environment. The analysis of eDNA can provide valuable information about the presence or absence of endangered or threatened species in their natural habitats. One of the most widely used methods for eDNA quantification is quantitative polymerase chain reaction (qPCR), which allows for the accurate and precise detection and quantification of specific DNA sequences.

There are several benefits to using eDNA quantification via qPCR for endangered or threatened species. Firstly, it is a non-invasive and cost-effective technique, which means that it can be used to monitor species without harming or disturbing them. This is particularly important for species that are difficult to capture or observe directly. Additionally, eDNA analysis can be conducted in a relatively short amount of time, which makes it a practical tool for monitoring programs that require frequent sampling.

Secondly, eDNA quantification via qPCR is highly sensitive and specific. It can detect very small amounts of DNA, even in samples with low DNA concentration or degraded DNA. This means that it is possible to detect species that are present in very low numbers or that are difficult to detect using traditional survey methods. Furthermore, qPCR can distinguish between different species based on their DNA sequences, which allows for the identification of multiple species in a single sample.

Finally, eDNA analysis via qPCR can provide information about the distribution and abundance of endangered or threatened species in their natural habitats. By analyzing eDNA from different locations, it is possible to map the distribution of a species and identify areas where it is more abundant or less common. This information can be used to inform conservation management strategies and to identify areas that require further protection.
