Doctoral thesis successfully defended!

Thanks to all my colleagues!

Thanks to all my colleagues!

On November 19th, 2014, I successfully defended my doctoral thesis entitled: “Modelling fish dispersal in catchments affected by multiple anthropogenic pressures”.

This thesis was conducted as part of the IWRM-Net Project IMPACT (, BMBF grant number 02WM1134) and is a cumulative work based on three research papers:

  1. Radinger, J. and Wolter, C. (2014). Patterns and predictors of fish dispersal in rivers. Fish and Fisheries, 15:456–473. DOI: 10.1111/faf.12028
  2. Radinger, J., Kail, J. and Wolter, C. (2013). FIDIMO – A Free and Open Source GIS based dispersal model for riverine fish. Ecological Informatics, 24:238-247. DOI: 10.1016/j.ecoinf.2013.06.002
  3. Radinger, J. and Wolter, C. (2014). Disentangling the effects of habitat suitability, dispersal and fragmentation on the distribution of river fishes. Ecological Applications. in press. DOI: 10.1890/14-0422.1

The major findings of the thesis are:

  • Fish dispersal is typically leptokurtic consisting of stationary and mobile components
  • We calculated quantitative dispersal parameters based on fish length, swimming performance, stream size and time
  • FIDIMO allows predicting and simulating spatio-temporal patterns of fish dispersal (e.g. time lags in fish response, minimum size of founder populations)
  • Besides restoring essential habitats their accessibility (spatial arrangement of source populations, position relative to barriers, the fish’s dispersal ability) is highly decisive

For all those who could not make it to my presentation of the results and who are still interested in the findings of my thesis here you can find my presentation on slideshare:
