Effects of Water Salinity on Growth and Survival of Common Eider (Somateria Mollissima) Ducklings
Abstract The need for fresh water may affect growth and survival of young waterfowl, including ducklings of sea ducks that are routinely raised in coastal marine habitats. We studied the influence of water salinity on growth and survival of Common Eider (Somateria mollissima) ducklings collected fro...
