From oligotrophy to dystrophy: the ontogeny of a humic lake in an extrazonal boreal taiga in Central Europe
ABSTRACT While humic lakes are common in northern Europe, in central Europe they are rare and our understanding of their ontogeny is insufficient. Here, we present the reconstruction of the development of a humic lake in the Tatra Mountains (Slovakia) over the last 8000 years using chironomids along...
