This series covers leading-edge research focusing on the environment, including current research data on water and nutrient use efficiency and root distribution of selected horticultural crops; development of green energy-saving mechanisms; sustainable research and technological development on bio-energy; lentic habitats as study models for assessing aquatic contamination; significant change-points of subperiod levels in tree-ring chronologies as indications of climate change; differences in bryophyte diversity between subalpine abies forests and larix plantations; and mosses as biomonitors of atmospheric pollution.
