Scenario analysis with a simulation model of the effect of waterbirds on phosphorus dynamics of a shallow freshwater ecosystem

open access: yesEnvironmental Challenges, 2022
Many freshwater systems throughout the world support a high number of waterbird congregations. Previous works suggest waterbirds have the potential to deposit a considerable amount of nutrients into the waterbody that may cause eutrophication.
