Environmental DNA (eDNA) has emerged as a transformative tool in ecological monitoring and biodiversity assessments. By retrieving genetic material from environmental samples such as soil, water, or air, researchers can identify and quantify species present in a given ecosystem without the need for direct observation or invasive sampling methods. In baseline surveys, which establish the current state of biodiversity and ecosystem health, eDNA offers several advantages, including increased sensitivity, efficiency, and the ability to detect elusive or rare species. This article explores the diverse applications of eDNA in baseline surveys, highlighting its benefits for conservation efforts, habitat management, and biodiversity monitoring, while also addressing challenges and future directions in the field.
Environmental DNA (eDNA) techniques are proving to be transformative in conducting ecological baseline surveys, enabling researchers to detect and monitor the presence of various species within ecosystems with high accuracy. Customary survey methods frequently enough require extensive fieldwork and can be limited by species detectability. In contrast, eDNA sampling allows for the collection of genetic material from environmental samples such as soil, water, or sediment, offering a non-invasive method to determine biodiversity. Key advantages of eDNA in ecological surveys include:
