Johannes Iversen
Appearance
Johannes Iversen (Danish pronunciation: palaeoecologist and plant ecologist.[1]
Biography
He was born in
late glacial flora. Iversen conducted a practical experiment with stone axe clear-cutting and slash-and-burn agriculture in a primeval forest to study the forest regeneration.[2][3]
In 1931, Iversen was first appointed assistant at the
