142Scott Petrie, Nelson Belzile & Yuwei Chen 4Food chain transfer and effects of selenium in w<strong>at</strong>erfowlA grant of $20,000Une subvention de 20 000 $Research Networks – <strong>Subventions</strong> de réseaux de rechercheThe combined continental popul<strong>at</strong>ion of Lesser (Aythya affinis) and Gre<strong>at</strong>erScaup (Aythya marila; hereafter scaup) declined by 50 % between themid-1980s and the l<strong>at</strong>e 1990s (Austin et al. 2000). One hypothesis for thedecline is th<strong>at</strong> birds are acquiring unhealthy contaminant burdens on thelower Gre<strong>at</strong> Lakes (LGL). This project has three inter-rel<strong>at</strong>ed parts:1. to determine levels of contaminant (particularly selenium) acquired byscaup (and other diving <strong>du</strong>cks) staging and wintering on the LGL;2. to evalu<strong>at</strong>e the contribution of Se contamin<strong>at</strong>ion from food as well assurrounding w<strong>at</strong>er and sediments; and3. to determine contaminant levels in Gre<strong>at</strong>er Scaup breeding on the Yukon-Kuskokwim Delta (YKD), Alaska.4 The names of the researchers from <strong>Laurentian</strong> <strong>University</strong> are shown in italics. This is a project within the “Metalsin The Holistic Environment” research network./Les noms des chercheurs de l’Université Laurentienne sont en italiques.Un project qui se situe a l’intérieur <strong>du</strong> réseau « Metals in The Holistic Environment ».
