Research themes and projects:

 

At the University of Groningen I have developed several research themes since 1976 that are interconnected. They range from ecohydrological approaches on the landscape scale to very detailed research on the habitat scale using micro-electrodes. Via restoration ecology I continued to work on ecohydrological relationships on the landscape scale again, but now in more or less natural mires in various countries and continents.

 

1976-1985: Effects of changes in hydrological conditions in wetlands.

Key words: vegetation science, groundwater regime, nitrogen mineralization, groundwater composition, groundwater abstraction, drainage.

Most of this work was carried out with master students. In 1985 I concluded this research with a thesis “Changes of groundwater regime in wet meadows”. Promotor was Prof Jan Barkman.

1980-1990: Development of eco-hydrological survey methods and prediction models on the landscape scale.

Keywords: vegetation mapping, prediction models, indicator values.

Together with people working in private ecological firms I developed an efficient method to map vegetation types and distribution pattern of wetland species in order to indicate qualitative aspects of local and regional hydrological systems. In 1991 two dissertations were published on vegetation development of river valley systems (Everts & de Vries 1991). These methods are still used in 4 private ecological firms. We also developed a computer model to predict changes in hydrological conditions due to groundwater abstraction.

1988-2002: Ecohydrological research in reference areas

Keywords: Hydrological modelling, analyses of natural isotope tracers, positive-feedback switches, semi-stable states, Radial Oxygen Loss (ROL), denitrification, mesocosms, micro-electrodes.

I started this eco-hydrological research in a rather descriptive way in the Netherlands and Belgium (thesis A.J.M. Jansen) and in the former German Democratic Republic where less disturbed lowland river valleys were still present (thesis Van Diggelen 1998). We established firm contacts with Prof Succow, who created the national Park and Nature reserves in Eastern Germany. Later we moved to Poland and the Dutch Wadden Sea islands. The research on the Wadden Sea islands was on eco-hydrological relations on the landscape scale, on acidification (thesis F.P. Sival 1997) and on nutrient limitation (thesis E.J.Lammerts 1998). In a later stage we started experimental and theoretical research on alternative stable states and impact of microbial mats and Radial Oxygen Loss on succession rates (thesis E.B. Adema 2003).

1991-2004: Restoration of acidified and desiccated wetlands.

Keywords: hydrological modelling, long term monitoring, seed bank analyses, nutrient availability, nutrient limitation, buffering capacity.       

Since 1990 I have participated in a national programme (OBN = Survival Plan of Dutch Nature) aimed at restoring acidified nature reserves due to high atmospheric nitrogen deposition and drainage in surrounding agricultural areas. In co-operation with managers we carried out restoration projects aimed at rewetting and reducing nutrient availability in acidified wetlands. Vegetation changes and environmental factors have been monitored in 13 areas for 6-16 years. Some results were published in PhD theses (Lammerts 1999, Van Duren 2000, Jansen 2000, Strijkstra 2000). A new PhD project will continue to relate observed vegetation and hydrological changes with climate change in dune areas (Dullo).

2002-2011: Water flow in natural bog ecosystems.

Keywords: buoyancy driven water flow, temperature regime, CO2-limitation, competition in hallow and hummocks,

In natural bog ecosystems we discovered that temperature driven water flow in the living Sphagnum layer could possible speed up the transport of nutrients, CO2 and oxygen from deeper layers to the top and vice-versa (PNAS 2003). This buoyancy driven water flow occurs in small convection cells of 4-8 cm in diameter. This phenomenon usually occurred during the night. Based on temperature differences and hydrological conductivity Adema (who worked in Groningen as a post-doc) was able to predict the exact time of occurrence of buoyancy driven water flow in Tierra del Fuego, where large differences occur during day and night in spring and autumn. In cooperation with Prof Elzinga (Groningen) a PhD project has started in 2006 (W. Patberg) on the physiological mechanisms of solute transport in Sphagnum plants and how this is influenced by buoyancy driven water flow. In cooperation with prof J. Roelofs (Nijmegen, NL) and prof. H. Joosten (Greifswald, DE) a new PhD project in Tierra del Fuego started in 2007 (C. Fritz) on competition between Sphagnum species and cushion plants (Astelia pumila) in coastal peatlands (C. Fritz).

2003-2013: Introducing eco-hydrological techniques and approaches to Eastern Europe and South Africa.

Keywords:, Hydrological modelling ,travertine formation, nutrient limitation, seed bank analyses, rewetting, stake holders, peat abstraction, biofuel.

Since 2003 I have coordinated two large eco-hydrological projects aimed at training NGO’s in eco-hydrology and restoration of wetlands. In Slovakia we worked with three counterparts on the restoration of calcareous mires and in Poland we worked with 7 counterparts on restoration of groundwater fed river valleys. The projects were funded by the Dutch government (Pin/Matra Program of the Ministries of Agriculture and Foreign Affairs) and carried out be a team of Dutch Scientists and Nature managers to educate counterparts in restoration and landscape analyses. One counterpart (Klimkowska) received a grant from the Groningen University to finish her PhD. In South Africa and Lesotho we have started cooperation with South African counterparts (J.P. & A. Grundling) and the University of Waterloo (J.Price, Canada). Future cooperation will include activities with Prof. Ellery (Rhodes University).

 

A focus point for the future will be on developing new strategies for a more natural and dynamic coastal development, in particular in the Dutch Wadden Sea islands.  This research includes population genetic studies on rare dune slack species since 2009 (R.Shahrudin) in cooperation with the University of Amsterdam (\Dr. Kooijman and dr. Oostermeijer).  I was also involved in developing eco-hydrological guidelines for dune habitats in England for English Nature in cooperation with the University of East Anglia. Since 2006 I am vice-president of a knowledge network of dune researchers and dune managers (OBN) aimed at developing restoration projects in the coastal area of the Netherlands.  I am responsible for developing a scientific program needed to increase the knowledge base of the network

 

Education and management skills: 

 

I have coordinated courses on: vegetation science, soil science, landscape ecology, eco-hydrology, science and society and restoration ecology. I have also much experience in problem driven education techniques. I regularly present lectures on eco-hydrology for nature managers, employees of water boards and civil servants as well as on Dutch universities.

Between 1978 and 1982 I was a member of the board of the sub-faculty Biology and also of the faculty Mathematics and Natural Sciences. In 1981 I was part of the reorganisation team of the sub-faculty Biology. Since then I have participated only in faculty commissions dealing with education. I was member of the faculty council (FWN) of the University of Groningen between 2010-2013. Between 1976 and 2013 I have coached ca 110 research projects of master students.
