Supervision ecological study (WUR, 2013) Due to prolonged drought periods and periodical decrease of groundwater levels the polder nature areas with fen ecosystems on floating mats (remnants of large fen mires) receive river water with an increased salinity compared to ambient levels. This affects the competitive abilities of fresh water fen systems and may cause decline of fen biodiversity and vegetation shift towards a species poor community. Study of effects of marginally increased salinity on the fitness of fen mire plants – an experimental study with various salinity levels and multiple plant species in the aqua-culture. Effects on biomass, root-shoot allocation, plant species growth response and traits.
Supervision and contribution in PhD study at WUR (Sija Stofberg), 2011-2014.
