How to maintain biodiversity

In the context of global change and loss of biotic diversity, understanding relationships between diversity and ecosystem functioning has become mandatory. Therefore, it is necessary to investigate underlying mechanisms that generate and maintain diversity patterns across spatial scales. Theresa Lumpi wrote her master’s thesis about this topic and finished successfully in September.


In this study we examined the effects of ecological connectivity along with important environmental parameters on freshwater microbial communities. Experimental communities were established in 40 mesocosms (300 L) inoculated with water from three lakes in Lower Austria.



From algae to fish

In September started the new FWF-project „GROW“, a cooperation between working group leader Martin Kainz and Ariana Chiapella (USA), who will work at WasserCluster for one year. In this project we will investigate dietary trajectories from various food sources to fish in established mesocosm settings.


The delineation of trophic pathways in aquatic food webs is necessary for evaluating the structure and flow of energy among organisms. Understanding the importance of each energy pathway is also necessary for studying food webs in the context of anthropogenic stressors.

About WasserCluster Lunz

WasserCluster Lunz  is a nonprofit research center shared to equal amounts by the University of Vienna, the Danube University Krems, and the University of Natural Resources and Life Sciences Vienna (BOKU Vienna). The research center is financially supported by the Provincial Government of Lower Austria and the Municipality of Vienna.


WasserCluster Lunz pursues basic and applied research on aquatic ecosystems. Our researchers work at the highest level on current questions of aquatic ecosystem research, such as questions of climate change, diversity research, water resource management or renaturation of waters.



WasserCluster Lunz pursues university and postgraduate training at an international level and accomplishes education-cooperation-projects and pedagogic outdoor activities on a regional level.
