Bioturbation enhances the aerobic respiration of lake sediments in warming lakes

Baranov, Viktor; Lewandowski, Jörg; Krause, Stefan

While lakes occupy less than 2% of the total surface of the Earth, they play a substantial role in global biogeochemical cycles. For instance, shallow lakes are important sites of carbon metabolism. Aerobic respiration is ...

Effects of bioirrigation of non-biting midges (Diptera: Chironomidae) on lake sediment respiration

Baranov, Viktor; Lewandowski, Jörg; Romeijn, Paul; Singer, Gabriel; Krause, Stefan

Bioirrigation or the transport of fluids into the sediment matrix due to the activities of organisms such as bloodworms (larvae of Diptera, Chironomidae), has substantial impacts on sediment respiration in lakes. However, ...

Eutrophication problems and their potential solutions in the artificial shallow lake Altmühlsee (Germany)

Schrenk-Bergt, Christiane; Krause, Dieter; Prawitt, Olaf; Lewandowski, Jörg; Steinberg, Christian E.W.

Lake Altmühlsee in Middle Franconia, Germany, was constructed as part of a water transportation system and flooded in 1986 by River Altmühl. Supply of nutrient rich water resulted in a hypertrophic state characterized by ...

Groundwater−Surface Water Interactions: Recent Advances and Interdisciplinary Challenges

Lewandowski, Jörg; Meinikmann, Karin; Krause, Stefan

The interactions of groundwater with surface waters such as streams, lakes, wetlands, or oceans are relevant for a wide range of reasons—for example, drinking water resources may rely on hydrologic fluxes between groundwater ...

Integral Flow Modelling Approach for Surface Water-Groundwater Interactions along a Rippled Streambed

Broecker, Tabea; Teuber, Katharina; Sobhi Gollo, Vahid; Nützmann, Gunnar; Lewandowski, Jörg; Hinkelmann, Reinhard

Exchange processes of surface and groundwater are important for the management of water quantity and quality as well as for the ecological functioning. In contrast to most numerical simulations using coupled models to ...

Is the Hyporheic Zone Relevant beyond the Scientific Community?

Lewandowski, Jörg; Arnon, Shai; Banks, Eddie; Batelaan, Okke; Betterle, Andrea; Broecker, Tabea; Coll, Claudia; Drummond, Jennifer; Gaona, Jaime; Galloway, Jason; Gomez-Velez, Jesus; Grabowski, Robert; Herzog, Skuyler; Hinkelmann, Reinhard; Höhne, Anja; Hollender, Juliane; Horn, Marcus; Jaeger, Anna; Krause, Stefan; Löchner Prats, Adrian; Magliozzi, Chiara; Meinikmann, Karin; Mojarrad, Brian Babak Morteza; Mueller, Birgit; Peralta-Maraver, Ignacio; Popp, Andrea; Posselt, Malte; Putschew, Anke; Radke, Michael; Raza, Muhammad; Riml, Joakim; Robertson, Anne; Rutere, Cyrus; Schaper, Jonas; Schirmer, Mario; Schulz, Hanna; Shanafield, Margaret; Singh, Tanu; Ward, Adam; Wolke, Philipp; Wörman, Anders; Wu, Liwen

Rivers are important ecosystems under continuous anthropogenic stresses. The hyporheic zone is a ubiquitous, reactive interface between the main channel and its surrounding sediments along the river network. We elaborate ...

Untersuchungen zum Einfluss seeinterner Verfahren auf die Phosphor-Diagenese in Sedimenten

Lewandowski, Jörg

Viele seeinterne Maßnahmen zielen darauf, die Phytoplanktonentwicklung über die Verfügbarkeit von Phosphor (P) im Wasserkörper zu steuern. Die meisten Restaurierungsverfahren sollen über eine Erhöhung der P-Bruttosedimentation ...
