Loss of diversity in bird communities after regulation of riverine meanders: How strong is the compensatory effect of mature growth on fishpond dams?

Popis výsledku v původním jazyce

Alterations to riverine ecosystems and the establishment of new man-made habitats along rivers have been accompanied by changes in vegetation composition and structure, which affect birds inhabiting riparian stands. We examined differences between bird communities inhabiting relict growth of river meanders and those inhabiting secondary plantations along the Otava and Blanice Rivers, Czech Republic. In addition, the study investigates whether the well-developed oak growth on artificial fishpond dams distributed widely through the studied landscape might compensate for the loss of bird biodiversity after river regulation. Breeding bird community and habitat attributes were studied on 30 fixed-width line transects and analysed using Multivariate Redundancy Analysis. Relict meanders were the most structurally diversified habitat type, with the highest species diversity and the great richness of forest birds.
