Agriculture and aquatic ecosystems

Agriculture is the dominant land use form in Lower Austria, covering more than 46 % of the total area. Agriculture delivers significant amounts of dissolved organic matter (DOM) to streams, thereby changing basic processes at the water-sediment interface and affecting the ecological state of the stream ecosystem. In January 2017 WasserCluster Lunz started the project “organic carbon cycling in streams” with project leader Gabriele Weigelhofer. The aim of the project is, thus, to investigate the influence of agricultural land use on the quantity and quality of DOM inputs to streams and to clarify the effects of this DOM on the aquatic carbon cycling in stream ecosystems.

Abstract

Effect of thermopeaking

Veronca Kasper wrote her master thesis under supervision of Thomas Hein about Microphytobenthos (MPB), small algae attached to a substrate. It plays a major role in lotic ecosystems and is often affected by multiple stressors. Thermopeaking (TP) combines stress of sudden flow velocity increase (Hydropeaking) and abrupt water temperature alteration. Although this effect is prevalent in alpine regions, studies concerning its influence on MPB are a critical knowledge gap. Therefore the aim of this project was to provide knowledge about the impact of TP on MPB, considering as well successional and habitat aspects.

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.

Research

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.

 

Education

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