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.
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.
