  <dc:description>&lt;p&gt;&lt;span&gt;Waterfowl&lt;/span&gt;&lt;span&gt;&amp;nbsp;are among the best studied and most extensively monitored species in the&amp;nbsp;world. Given their global importance for sport and subsistence hunting, viewing and&amp;nbsp;ecosystem functioning, great effort has been devoted since the middle part&amp;nbsp;&lt;/span&gt;&lt;span&gt;of&lt;/span&gt;&lt;span&gt;&amp;nbsp;the&amp;nbsp;20th century&amp;nbsp;&lt;/span&gt;&lt;span&gt;to&lt;/span&gt;&lt;span&gt;&amp;nbsp;understanding both the environmental and demographic mechanisms&amp;nbsp;that influence&amp;nbsp;&lt;/span&gt;&lt;span&gt;waterfowl&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span&gt;population&lt;/span&gt;&lt;span&gt;&amp;nbsp;and community dynamics. Here we use&amp;nbsp;comparative approaches&amp;nbsp;&lt;/span&gt;&lt;span&gt;to&lt;/span&gt;&lt;span&gt;&amp;nbsp;summarise and contrast our understanding&amp;nbsp;&lt;/span&gt;&lt;span&gt;of&lt;/span&gt;&lt;span&gt;waterfowl&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span&gt;population&lt;/span&gt;&lt;span&gt;&amp;nbsp;dynamics across species as short-lived as the&amp;nbsp;&lt;/span&gt;&lt;span&gt;teal&lt;/span&gt;&lt;span&gt;&amp;nbsp;Anas discors and A.crecca&amp;nbsp;&lt;/span&gt;&lt;span&gt;to&lt;/span&gt;&lt;span&gt;&amp;nbsp;those such as the swans Cygnus sp. which have long life-spans. Specifically, we focus&amp;nbsp;on&amp;nbsp;&lt;/span&gt;&lt;span&gt;population&lt;/span&gt;&lt;span&gt;&amp;nbsp;responses&amp;nbsp;&lt;/span&gt;&lt;span&gt;to&lt;/span&gt;&lt;span&gt;&amp;nbsp;vital rate perturbations across life history strategies,&amp;nbsp;discuss bottom-up and top-down responses&amp;nbsp;&lt;/span&gt;&lt;span&gt;of&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span&gt;waterfowl&lt;/span&gt;&lt;span&gt;populations&amp;nbsp;&lt;/span&gt;&lt;span&gt;to&lt;/span&gt;&lt;span&gt;&amp;nbsp;global&amp;nbsp;change, and summarise our current understanding&amp;nbsp;&lt;/span&gt;&lt;span&gt;of&lt;/span&gt;&lt;span&gt;&amp;nbsp;density dependence across&amp;nbsp;&lt;/span&gt;&lt;span&gt;waterfowl&lt;/span&gt;&lt;span&gt;&amp;nbsp;species. We close by identifying research needs and highlight ways&amp;nbsp;&lt;/span&gt;&lt;span&gt;to&lt;/span&gt;&lt;span&gt;&amp;nbsp;overcome the challenges&amp;nbsp;&lt;/span&gt;&lt;span&gt;of&lt;/span&gt;&lt;span&gt;&amp;nbsp;sustainably managing&amp;nbsp;&lt;/span&gt;&lt;span&gt;waterfowl&lt;/span&gt;&lt;span&gt;&amp;nbsp;populations in the 21st&amp;nbsp;century.&lt;/span&gt;&lt;/p&gt;</dc:description>
