A Balaton halállományának jellemzése környezeti DNS mintavételek alapján

Abstract

In ecological studies, a sample that reflects the structure of communities is needed in order to monitor community diversity, properly operate environmental assessment systems, and develop environmental management plans. However, achieving a representative sample is not a simple task, as it is affected by a number of factors. When monitoring freshwater fish communities, the results can depend significantly on the selectivity of the sampling methods used, in addition to abiotic and biotic characteristics of the environment. Assessments based on environmental DNA sampling may be a promising complement or in the future, even an alternative to traditional methods. However, there is still a lack of knowledge on its applicability, for example, its effectiveness in different habitat types and organism groups has not been determined. In our work, we compared the results of traditional and environmental DNA sampling surveys to characterize the fish community structure of Lake Balaton.
