Research

Currently, I am involved in the following project(s):

Anthropogenic fragmentation has particularly strong effects in dendritic networks, like river-scapes, where there is only one connecting route between two locations. Man-made obstacles, such as dams and weirs, often form absolute barriers for upstream migration, with many negative effects on fish communities. Restoring connectivity by removing barriers is thus important for improving the functioning of stream-lake networks, but may have unwanted side-effects by facilitating the spread of invasive species. The project is named ODYSSEUS in reference to the dilemma faced by Odysseus when navigating between Scylla (a six-headed monster) and Charybdis (a whirlpool) in the narrow strait of Messina. Within ODYSSEUS I am mainly involved in modelling the joint effects of longitudinal connectivity and future global on the native an non-native fishes of River Ebro.

 

Previously, I was involved in the following projects:

Developing an Integrated Model to Predict Abiotic Habitat Conditions and Biota of Rivers Application in Climate Change Research and Water Management. IMPACT couples abiotic (hydrologic, hydraulic, hydrodynamic) and biotic models (dispersal and habitat suitability) on different spatial scales (from catchment to river reaches). My main task comprise of fish dispersal and fish habitat modelling. As one of my main outcomes of IMPACT, a Free and Open Source GIS module for modelling fish dispersal FIDIMO was developed.

Project duration: 2010-2013
Funding: Commission of the European Communities (RTD programme “IWRMNET”); German Federal Ministry for Education and Research, BMBF (grant number 02WM1134)

  • FISHCON

Biodiversity scenarios for fragmented landscapes; freshwater connectivity 
and the future of fish diversity. Within FISHCON, the fish dispersal model FIDIMO will be further developed and applied to various European catchments of different size.

Project duration: 2013-2016
Funding: Biodiversa project; funded by the German Federal Ministry for Education and Research, BMBF (grant number 01LC1205)
