  <dc:description>&lt;p&gt;&lt;span id="_mce_caret" data-mce-bogus="1" data-mce-type="format-caret"&gt;&lt;span&gt;Aquatic invasive species (&lt;/span&gt;&lt;abbr title="Aquatic invasive species"&gt;AIS&lt;/abbr&gt;&lt;span&gt;) are amongst the greatest threats to native aquatic biodiversity. These introduced species often thrive in human-altered environments and spread through human-mediated pathways to invade new watersheds.&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span&gt;&lt;span class="tn" data-obkms-id="A16DA7FF-D7FB-4AD3-835F-99B93BA82C75" data-taxon-parsed-name="Corbicula fluminea"&gt;&lt;span class="genus"&gt;Corbicula&lt;/span&gt;&amp;nbsp;&lt;span class="species"&gt;fluminea&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;is a freshwater bivalve native to southeastern Asia first introduced in North America in Seattle, WA, in 1938 and has spread to nearly every major watershed in the southeastern United States. In the present study, we use an information theoretic framework to compare landscape and stream habitat variables associated with&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span&gt;&lt;span class="tn" data-obkms-id="813E4410-4458-4B8D-819C-7AD762E93B4A" data-taxon-parsed-name="Corbicula fluminea"&gt;&lt;span class="genus"&gt;C.&lt;/span&gt;&amp;nbsp;&lt;span class="species"&gt;fluminea&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;presence across five&amp;nbsp;&lt;/span&gt;&lt;abbr title="Hydrologic Unit Code 10"&gt;HUC10&lt;/abbr&gt;&lt;span&gt;&amp;nbsp;watersheds in the upper Savannah River basin of South Carolina and Georgia, USA. Predictive models included landscape-level and site-level habitat variables associated with agricultural, developed, and forested landscapes. Models with variables associated with forested and developed landscapes were the top performing models based on&amp;nbsp;&lt;/span&gt;&lt;abbr title="Akaike’s Information Criterion"&gt;AICc&lt;/abbr&gt;&lt;span&gt;&amp;nbsp;values. In top performing models&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span&gt;&lt;span class="tn" data-obkms-id="45DDD45E-6964-4020-898E-561169E8262A" data-taxon-parsed-name="Corbicula fluminea"&gt;&lt;span class="genus"&gt;C.&lt;/span&gt;&amp;nbsp;&lt;span class="species"&gt;fluminea&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/i&gt;&lt;span&gt;&amp;nbsp;presence was positively correlated with increased stream width, but negatively correlated with substrates dominated by cobble. Lower performing models highlight positive correlations with the presence of upstream reservoirs and increased developed landscape surrounding the site. Identification of habitat and landscape correlates with invasive species presence may lead to more efficient introduction monitoring efforts for conservation managers.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;</dc:description>
