How is eDNA (environmental DNA) technology used in species conservation?

eDNA (environmental DNA) technology has revolutionised the field of conservation. It allows the analysis of DNA traces left behind by different species in the environment. With eDNA technology, researchers can identify and monitor species in the environment, even if they are not visible or difficult to observe.

The basis of eDNA technology is that living organisms leave DNA traces in the environment. Collecting eDNA samples is a simple and non-invasive method that does not require direct contact with living organisms. Researchers usually collect water or soil samples and then isolate and analyse the eDNA in these samples.

eDNA technology has many advantages for species conservation. First, it allows a more accurate assessment of the presence and distribution of species. Through eDNA analysis, researchers can identify species in the environment, even if they are not visible or difficult to observe. This can provide more accurate data on species distribution and populations.

Secondly, eDNA technology allows the identification of endangered and rare species. By analysing eDNA samples, researchers can identify species whose presence is low or unknown. This can help protect such species and take appropriate measures to help populations grow.

Thirdly, eDNA technology also allows researchers to study the effects of environmental changes. eDNA analysis can be used to track changes in species populations and their responses to environmental changes. In this way, eDNA technology can contribute to a better understanding of the effects of environmental change and to taking appropriate measures to conserve species.

eDNA technology has therefore revolutionised the field of species conservation. It allows species to be identified and monitored by analysing DNA traces in the environment. The benefits of eDNA technology include a more accurate assessment of the presence and distribution of species, the identification of endangered and rare species, and the assessment of the effects of environmental changes. eDNA technology is a promising tool for species conservation that can help protect species and conserve biodiversity.
