  <dc:description>&lt;p&gt;&lt;i&gt;Hemimysis anomala&lt;/i&gt;&lt;span&gt;&amp;nbsp;is one of the latest macroinvertebrates to invade the Laurentian Great Lakes. Since first reported in 2006,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Hemimysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;have been confirmed in several locations within the Great Lakes basin. However, little is known about the seasonal and spatial variation&amp;nbsp;in demographics and dynamics of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Hemimysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;populations. We used a standardised pier-based methodology to describe the distribution of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Hemimysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;at 29 locations around the shoreline of Lake Ontario in 2009. Samples were collected in spring, summer, and fall at most locations, and bi-weekly at one site (Bronte Creek) over a 12-month period in 2009. For each site, we estimated abundance by sex and size. The more temporally intensive sampling at Bronte Creek enabled us to estimate production.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Hemimysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;were found at 83% of the sites visited, with densities generally highest in the northwest and lower at the other sites. Production estimates (2.67–14.09&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span&gt;mg dry weight·m&lt;/span&gt;&lt;sup&gt;−&amp;nbsp;2&lt;/sup&gt;&lt;span&gt;·d&lt;/span&gt;&lt;sup&gt;−&amp;nbsp;1&lt;/sup&gt;&lt;span&gt;) were higher than that of other common zooplankton species in the Great Lakes. We provide important life history parameters that will help ecologists better understand the potential impacts of&amp;nbsp;&lt;/span&gt;&lt;i&gt;Hemimysis&lt;/i&gt;&lt;span&gt;&amp;nbsp;on Great Lakes ecosystems.&lt;/span&gt;&lt;/p&gt;</dc:description>
