European lake shores in danger — concepts for a sustainable development

Klaus Schmieder

Limnologica > 2004 > 34 > 1-2 > 3-14

In Europe, when small (> 0.01 km ² ) lakes are considered, approximately 500,000 natural lakes occur. This considerable number points to the fact that lakeshore habitats and ecosystems are of significant importance to the total biodiversity of European landscapes, not only because of their expanse, but also because they are ecotones between land and water, which attract many kinds of wildlife,...

Managed water levels and the expansion of emergent vegetation along a lakeshore

Hugo Coops, J. Theo Vulink, Egbert H. van Nes

Limnologica > 2004 > 34 > 1-2 > 57-64

Water-level fluctuations may be used to promote the expansion of emergent vegetation along lakeshores. We present the case of the lake Volkerak-Zoommeer in the Netherlands, a fresh-water lake created in 1987 after the enclosure of an estuary. Using an experimental area in which the water level could be manipulated, it was shown that partial summer drawdown of the shoreline created suitable conditions...

Die Auswirkungen der Wasserstände am Bodensee auf das Deschampsietum rhenanae zwischen 1989 und 2003

Irene Strang, Michael Dienst

Limnologica > 2004 > 34 > 1-2 > 22-28

The Deschampsietum rhenanae is an endemic and endangered lakeshore community growing in the upper littoral of Lake Constance, the occurrence of which has been reduced dramatically during the last 100 years. The existence of this community depends on the seasonal water level changes of the unregulated, prealpine Lake Constance. Long-term monitoring indicates that the typical species of the Deschampsietum...

Public participation in monitoring programmes as a tool for lakeshore monitoring: the example of Lake Pyhäjärvi, Karelia, Eastern Finland

Ritta Niinioja, Anna-Liisa Holopainen, Liisa Lepistö, Anita Rämö, more

Limnologica > 2004 > 34 > 1-2 > 154-159

Lake Pyhäjärvi, on the border between Finland and Russia in Karelia, is a very valuable clear-water lake of the Lobelia type. It belongs to the European Union's Natura 2000 programme in Finland, and has been included in regional and national monitoring programmes since the 1960s. The main monitoring station is situated near the outlet of the lake. Deterioration of its water quality was suspected already...

The use of soft shore protection measures in shallow lakes: Research methodology and case study

Selim M. Sayah, Jean-Louis Boillat, Anton Schleiss

Limnologica > 2004 > 34 > 1-2 > 65-74

Shore protection in lakes is an issue of major importance in Switzerland where several big lakes in plains suffer from a pronounced bank erosion. For the moment, in shallow lakes, soft and biotechnical protection measures proved their reliability. Unfortunately, the scientific basis for the design of such techniques does not exist in some cases or not appropriate enough in order to have an optimized...

Lake victoria: The water hyacinth (Eichhornia crassipes [Mart.] Solms), its socio-economic effects, control measures and resurgence in the Winam gulf

George Ogueno Opande, John Charles Onyango, Samuel Otieno Wagai

Limnologica > 2004 > 34 > 1-2 > 105-109

The aquatic weed Eichhornia crassipes [Mart.]Solms was introduced in Lake Victoria from Rwanda via the Kagera River by the activities of man. After originally infesting Lake Victoria (Uganda), it eventually spread into the Winam gulf, where its proliferation was spectacular, resulting in an enormous public outcry. The aim of this study was to find out how a beach/bay covered by a weed carpet affected...

Dynamik der Schilfröhrichte am Bodensee unter dem Einfluss von Wasserstandsvariationen

Michael Dienst, Klaus Schmieder, Wolfgang Ostendorp

Limnologica > 2004 > 34 > 1-2 > 29-36

On the basis of different sets of aerial photos the dynamics of the reed bed areas of Lake Constance were investigated in relation to the dynamics of the water levels. The objectives of the study were to quantify the changes of reed areas due to different flood events in the last decades and their recovery in the time periods between these events. The results should given information of the relevance...

Bruthabitatmodellierung für den Drosselrohrsänger (Acrocephalus arundinaceus L.) als Bestandteil eines integrativen Managementsystems für Seeufer

Annette Woithon, Klaus Schmieder

Limnologica > 2004 > 34 > 1-2 > 132-139

Within the context of the European legislative (e.g. Water Framework Directive, Natura 2000 network) monitoring and assessment of wetland areas are of great significance. This research points out the relevance of spatially explicit habitat models as an essential part of a decision support system for lake shore management. The Great Reed Warbler (Acrocephalus arundinaceus L.) was selected as a key...

Water level variability and trends in Lake Constance in the light of the 1999 centennial flood

Klaus D. Jöhnk, Dietmar Straile, Wolfgang Ostendorp

Limnologica > 2004 > 34 > 1-2 > 15-21

The extreme flood of Lake Constance in 1999 focused attention on the variability of annual lake levels. The year 1999 not only brought one of the highest floods of the last 180 years but also one of the earliest in the season. The 1999 extreme event was caused by heavy rainfall in the alpine and pre-alpine regions. The influence of precipitation in the two distinct regional catchments on lake level...

Planktonic algae and epiphyton of the littoral in lake Peipsi, Estonia

Reet Laugaste, Külli Lessok

Limnologica > 2004 > 34 > 1-2 > 90-97

The littoral plankton of Lake Peipsi (3555 km ² , mean depth 7.1 m) was studied in summer 1980 and 2000–2002, and the epiphyton was studied on two dominating macrophytes, Phragmites australis (Cav.) Trin. ex Steud. and Potamogeton perfoliatus L., in 2000. The purpose of the study was to estimate to what extent the littoral phytoplankton and epiphytic algae (their biomass, chlorophyll a content...

Fish in the littoral zone: ecology, threats and management

Ian J. Winfield

Limnologica > 2004 > 34 > 1-2 > 124-131

The importance of the littoral zone of lakes to a diversity of fish species has been appreciated for many centuries, although the complexity and heterogeneity of this habitat have resulted in a poorer understanding of local fish ecology compared with that achieved for typically much larger but simpler offshore habitats. Lake fish species may occupy the littoral zone permanently or visit it on diel,...

Influence of water level fluctuation on the spatial dynamic of the water chemistry at Lake Fertõ/Neusiedler See

Mária Dinka, Edit Ágoston-Szabó, Árpád Berczik, Gyula Kutrucz

Limnologica > 2004 > 34 > 1-2 > 48-56

Lake Fertõ/Neusiedler See is a steppe lake situated on the Hungarian-Austrian border with a surface area of 309 km ² . It is an extremely shallow lake with regulated outflow. 54% of the whole lake and 85% of the Hungarian part (75 km ² ) is covered by reed. There are numerous reedless areas (inner ponds) of variable size within the reed belt, which is enmeshed with canals connecting...

Density control in Potamogeton perfoliatus L. and Potamogeton pectinatus L.

Susanne R. Wolfer, Dietmar Straile

Limnologica > 2004 > 34 > 1-2 > 98-104

The effect of density on the growth, recruitment of new ramets, biomass allocation, rhizome spacer length and rhizome branching of the submersed macrophyte Potamogeton perfoliatus L. was experimentally evaluated in a mesocosm with three different initial shoot densities. The findings suggest that the number of primary shoots available in the beginning of the season can strongly influence patterns...

Lake Koronia, Greece: Shift from autotrophy to heterotrophy with cultural eutrophication and progressive water-level reduction

Chrysoula Mitraki, Thomas L. Crisman, George Zalidis

Limnologica > 2004 > 34 > 1-2 > 110-116

Lake Koronia, a Ramsar site, is shallow, polymictic, hypertrophic and until recently was aerially the fourth largest lake in Greece. Although exceeding 5 m in the past, lake depth has declined progressively from 3.8 m in 1980 to < 1 m in 1997, reducing surface area and water volume by 50% and 80%, respectively. Specific conductivityincreased from 1300 μS cm ⁻¹ in 1977 to >6000 μS cm...

Characteristics of reeds on Lake Peipsi and the floristic consequences of their expansion

Helle Mäemets, Lilian Freiberg

Limnologica > 2004 > 34 > 1-2 > 83-89

The reeds of Lake Peipsi (surface area 3555 km ² , mean depth 7.1 m, max. depth 15.3 m, not-regulated) have increased through the last 30 years. The most significant increase has taken place in the larger formerly mesotrophic northern part where the mean air-dry biomass of reed shoots has increased from 20 g m ⁻² in 1970 through 789 g m ⁻² in 1989 to 1563 g m ⁻² in...
