Captive birds that eat more have higher gastrointestinal throughput rates, and thus likely lower digestive efficiencies. Density-dependent rates of ingestion coupled with decreasing digestive efficiency means that penguins will tend to impact prey stocks more when fish densities are high. This may contribute to the stability of predator/prey relations in marine systems and should be considered in fishing policies as well as in estimates of top predator consumption rates.<o:p></o:p></span></p> <p class=MsoNormal><span lang=EN-GB style='mso-ansi-language:EN-GB'><![if !supportEmptyParas]>&nbsp;<![endif]><o:p></o:p></span></p> <p class=MsoNormal><span lang=EN-GB style='mso-ansi-language:EN-GB'><b>Keywords:</b></span><span lang=EN-GB style='mso-ansi-language:EN-GB'> Magellanic Penguins, <i>Spheniscus magellanicus,</i></span><span lang=EN-GB style='mso-ansi-language:EN-GB'> feeding habits, consumption, digestion</span></p> </div> </body> </html>
