  <dc:description>&lt;p&gt;1. Blood samples were collected from mallard ducks after 6, 12, and 18 weeks of dietary exposure to mash containing 0.015%, 0.150%, and 1.500% crude oil.&lt;/p&gt;&lt;p&gt;2. Plasma corticosterone concentrations in ducks fed mash containing 0.150% or 1.500% Alaskan Prudhoe Bay crude oil were uniformly depressed when compared to values in untreated control birds.&lt;/p&gt;&lt;p&gt;3. Plasma thyroxine concentration was not altered in ducks chronically exposed to crude oil.&lt;/p&gt;&lt;p&gt;4. The observed alteration in corticosterone concentration could reduce tolerance to temperature and dietary fluctuations in the environment.&lt;/p&gt;</dc:description>
