  <dc:description>&lt;div id="Abs1-section" class="c-article-section c-article-content-visibility"&gt;&lt;div id="Abs1-content" class="c-article-section__content"&gt;&lt;p&gt;Invasive species introductions in high latitudes are accelerating and elevating the need to address questions of their effects on Subarctic and Arctic ecosystems. As a driver of ecosystem function, submerged aquatic vegetation is one of the most deleterious biological invasions to aquatic food webs. The aquatic plant&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Elodea&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;spp. has potential to be a widespread invader to Arctic and Subarctic ecosystems and is already established in 19 waterbodies in Alaska, USA.&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Elodea&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;spp. has been found to alter ecosystem processes through multiple pathways; yet little is known about the impact of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Elodea&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;spp. on fish life history. A primary concern is the effect of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Elodea&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;spp. on juvenile Pacific salmon (&lt;i&gt;Oncorhynchus&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;spp.), because this invading plant can form dense stands in littoral zones, potentially impacting important freshwater rearing habitats used by juvenile fish for foraging and refuge from predators. We used a field experiment to test the effect of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Elodea&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;spp. on juvenile coho salmon (&lt;i&gt;O. kisutch&lt;/i&gt;) growth in an infested lake near Cordova, Alaska, USA. We found that&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Elodea&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;spp. stands result in reduced growth and a lower trophic position for juvenile coho salmon over the summer compared to habitats dominated by a native assemblage of aquatic plants. While infested sites were not associated with significant changes in water condition or primary productivity compared to sites dominated by native vegetation, zooplankton densities were reduced, and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Elodea&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;spp. height and vegetation richness increased macroinvertebrate densities. Combined, these results indicate that&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Elodea&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;spp. may alter the flow of energy to juvenile salmon by restructuring space and affecting prey resources for rearing fish. Furthermore, these results suggest that widespread establishment of&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Elodea&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;spp. may alter the quality of habitat for juvenile salmon and, by affecting juvenile fish growth, could lead to population-level impacts on salmon returns.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;</dc:description>
