Brief description of the main scopes: 

1) Field of research: 

  • Spatial and temporal diversity patterns of fish assemblages: Using binary (presence--absence) and abundance data, we study fish--environment relationships at scales with small ( (100-1 m) and large (102-3 m)resolution. We are especially interested in identification of the most important environmental factors that affect distribution of fishes.
  • Aquatic Conservation:
    Knowing the most important environmental factors that influence fishes allow us 1) to make recommendations for conservation and restoration of riverine habitats, and eco-friendly interventions; 2) to assess ecological status of surface waters in accordance of the EU Water Framework Directive.

2) Activity profile:

  • Field sampling of fishes:
    We usually use electrofishing gears from boat or by wading, and sometimes different kinds of nets to sample fish assemblages. 
  • Ecological data processing:
    Field data are studied and summarized by general statistical methods, multivariate techniques such as ordinations and cluster analyses, and machine learning methods.
