  <dc:description>&lt;div id="abstracts" class="Abstracts u-font-serif"&gt;&lt;div id="ab0005" class="abstract author" lang="en"&gt;&lt;div id="as0005"&gt;&lt;p id="sp0050"&gt;&lt;i&gt;Hemimysis anomala&lt;/i&gt;&lt;span&gt;&amp;nbsp;is a recent invader to North American&amp;nbsp;aquatic ecosystems&amp;nbsp;and is spreading rapidly throughout the Great Lakes region. This is the first&amp;nbsp;littoral&amp;nbsp;mysid in the North American Great Lakes; and, as such, the ecosystem effects are unknown and could be substantial. These effects depend on the role of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Hemimysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;in the food web and, therefore, on its diet. We examined the stomach contents of two life stages of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Hemimysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;from two sites in Lake Ontario during the growing season (May–November 2010). We also report the relationship between zooplankton hard parts and size for a number of potential prey species to allow the back-calculation of prey lengths from stomach contents. Both juvenile (2–5&amp;nbsp;mm) and adult&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Hemimysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(5–11&amp;nbsp;&lt;span&gt;mm) were omnivorous, consuming&amp;nbsp;phytoplankton, zooplankton, and&amp;nbsp;benthos&amp;nbsp;when available. However, adults appeared slightly more carnivorous and incorporated larger prey in their diets.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Hemimysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;were able to consume zooplankton prey up to 30% of their own length, including&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Bythotrephes longimanus&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Cercopagis pengoi&lt;/i&gt;.&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Daphnia&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Bosmina&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;were selected over other prey by both juvenile and adult&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Hemimysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and were most common in stomachs during July and September when their abundances in the zooplankton were highest. Measurements of δ&lt;sup&gt;13&lt;/sup&gt;C and δ&lt;sup&gt;15&lt;/sup&gt;&lt;span&gt;N corroborated stomach content materials, indicating an omnivorous diet which included benthic and pelagic sources.&amp;nbsp;Omnivory&amp;nbsp;by&amp;nbsp;&lt;/span&gt;&lt;i&gt;Hemimysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;is typical of mysids in general and makes them less sensitive to seasonal dynamics of preferred prey items.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
