The Styrian government - A13 has contracted us to study the distribution and densities of the Otter in Styria, in co-operation with Steven Weiß (University Graz, Institute for Biology).
The multiple martial arts world champion introduced us into various protection techniques. It lead to interesting experiences and black and blue markings...Körper Kampf Kunst Austria
In 2013 and 2014, the agricultural experimental station in Wies (DI Doris Lengauer) conducted experiments with flower strips in plastic tunnel greenhouses.
The main goal of the study was the development of tailored flower strips at the tunnel margins to facilitate populations of beneficial arthropods as antagonists against aphids, whiteflies, thrips and spider mites. We studied True Bugs, Hymenoptera, Robber Flies, Hover Flies und Beetles, in co-operation with Esther Ockermüller and Erwin Holzer. The results are very interesting: The biodiversity increases, both beneficial arthropods and suporters of pest species (e.g. ants) profit from flower strips.
Positive effects prevail, flower strips enhance biodiversity and the presence of beneficial arthropods.
We monitor the Otter population in Styria in co-operation with the University of Graz (Prof. Steven Weiss) by a spraint survey under 650 bridges (same as studied by Andreas Kranz in 2011) and by estimating otter densities with molecular methods within selected study areas.
The main goal of the project is a good estimation of the distribution and population size of the otter in Styria.
We studied this question in 2016/2017 by sampling Invertebrates on six meadows and collected more than 147.000 specimens.
The results of this study are summarized hiere:DOWNLOAD
Half of the Gesäuse National Park is covered by forests. In co-operation with Erwin Holzer and Carsten Morkel, we studied saproxylic beetle and Aradidae bug species in the National Park and identified the most important forests sites for biodiversity conservation issues.
Using window traps on 30 sites, we collected 1553 beetles from 231 species (Ø 15-30 species/site). Decidous forests north of the Enns river showed the highest species diversity. We also found eight aradid bugs and a very rare, saproxylic planthopper. Their presence is dependant upon higher amounts of deadwood.
To further enhance biodiversity, we recommend to leave any dead wood (also after catastrophic events) untouched.
