Master and PhD-theses


PhD position - BOKU Doctoral Program HR21

Within the frame of the BOKU Doctoral Program HR21 (Human River Systems in the 21st century) we offer a PhD position (30 hours per week) for the duration of three years. You will work in an interdisciplinary team at the Institute of Hydrobiology and Aquatic Ecosystem Management and contribute to ongoing projects.

Master Thesis - Glyphosate

Bioaccumulation of Glyphosate and its degradation products in aquatic snails -Effects on growth, survival, activity and metabolism *Experimental flume approach *

Master thesis 2018/2019

The role of macrophytes in the nutrient cycling of Austrian lowland rivers.
How is the distribution and abundance of macrophytes linked to nutrients, sediments and hydrology and what are the implications?

Master thesis 2018/2019

The effect of Glyphosate on benthic algae, macroinvertebrates and how this influences the trophic cascade (05.02.2018)

Master thesis 2018/2019

The effect of dead wood on the colonization pattern of periphyton (05.02.2018)

Master thesis 2018/2019

The use of benthic algae as indicators for hydrological stress (hydropeaking) (05.02.2018)

PhD Thesis

Organic carbon cycling in streams: Effects of agricultural land use
The aim of the project is 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 at different global warming scenarios. (10.01.2017)

Master Thesis

Impact of hydropeaking on benthic invertebrates
Assess & observe drift activities of different benthic invertebrate species following abruptly increased flow conditions (hydropeaking). We will test a gradient of different up-ramping speeds as well as different peak flows. (10.01.2017)
