Master of Science in ecology/limnology at the University of Innsbruck in 1998, on ecological evaluation of running waters in Luxemburg with application of geographical information systems (GIS). Ph.D. thesis at UIBK-IZL since 1999 on GIS, remote sensing and image analysis in limnology. Expertise in assessment of habitat and anthropogenic impact on running waters and lakes, environmental information systems (remote sensing, photogrametry and environmental classification).

Diploma at the University of Padova (Italy), on photosynthetic bacteria of a meromictic mountain
lake in the Eastern Italian Alps. Ph.D at the University of Innsbruck in 2000, on general
limnology, phytoplankton and littoral diatoms of high mountain lakes in the Eastern Italian Alps.
Expertise in phytoplankton and diatom analyses of high mountain lakes and in enclosure
experiments. Participation in national and EC research projects concerning lowland river margins
and glacial streams (ERMAS 1995-1997, AASER 1996-1998). |
Tasks:
UIBK-IZL convenes the work package on "evaluation:
environmental status of lakes" (WP 8)
and with UIBK-IMG co-ordinates the
hydrological studies within EMERGE. UIBK-IZL runs the Experimental
site at Gossenkollesee in the Austrian Tyrol, including the
installation and operation of large, automatic sediment traps in
collaboration with EAWAG; and the
ana--lyses of diatoms from these traps. UIBK-IZL is responsible
for all field sampling at the Classification and Validation lakes
in the Tyrol Lake District and will organise the GIS mapping
programme for the this region. In the RILA Mountains UIBK-IZL
co-ordinates the survey of catchment data (vegetation, soil cover,
geology) and analyses diatoms in the sediment cores and interpret
the geochemical changes in the lake sediment, in co-operation with
IZ-BAS. Along an altitudinal
gradient of 5 lakes catchment parameters are surveyed and analysis
of long term trends in limnochemistry in relation to climate,
weathering, soil development and vegetation are carried out to
statistically evaluate the driving factors for limnochemical
changes in these lakes. UIBK-IZL participates in fish sampling in
Austria, Bulgaria, Norway and Spain for biochemical analyses and
trains local staff if more than one sampling is
scheduled. Oxidative stress and biochemical parameters in the
liver of all fish (GSH, GSSG, vitamin C, riboflavin, tocopherol,
carotenoids, enzymes linked to detoxification) are analysed in
Innsbruck; and pollutant fluxes and impact within the food chains
are assessed in collaboration with CSIC (POPs), NIVA (stable isotopes and metals), CNRIII (pigments and carotenoids in
sediment). In two Bulgarian lakes UIBK-IZL supervises the complete
fish sampling programme including test fishing, sampling of blood
(blood ions) and gills (scanning electron microscopy), in
co-operation with IZ-BAS.
