| Description
| - Waterfowl management on breeding grounds focuses on improving nest success, but few studies have compared waterfowl nest success and factors affecting nest survival along a wetland gradient and simultaneously identified nest predators. We monitored nests (n = 195) of common pochards (Aythya ferina) in Trebon Basin Biosphere Reserve, Czech Republic, during 1999-2002. Daily nest survival rates (DSRs, logistic-exposure) declined from island (0.985, 95% confidence interval, 0.978-0.991) to overwater (0.962, 0.950-0.971) and terrestrial (0.844, 0.759-0.904) nests. The most parsimonious model for DSRs included habitat class (DSRs: island > overwater > terrestrial) and nest visibility. Nest survival was improved by reduced nest visibility, increased water depth, and increased distance from the nest to habitat edge in littoral habitats. On islands, nest success increased with advancing date and increased distance to open water. A model of constant nest survival best explained the data for terrestrial ne

- Management kachen se zaměřuje na zlepšování hnízdní úspěšnosti, ale dosud málo studií srovnávalo hnízdní úspěšnost a současně zjišťovalo hnízdní predátory podél celého mokřadního gradientu. Monitorování přirozených hnízd poláka velkého na Třeboňsku odhalilo pokles hnízdní úspěšnosti od ostrůvků, přes litorál, směrem k terestrickému prostředí. Pokus s umělými hnízdy odhalil stejný trend v celkovém přežívání hnízd a současný nárust významu savčích predátorů směrem k terestrickému prostředí. Výsledky dokládají význam rybníčních ostrůvků a širokého pásu litorální vegetace pro bezpečné hnízdění kachen. (cs)
