  <dc:description>&lt;p&gt;&lt;i&gt;Melilotus albus&lt;/i&gt;&lt;span&gt;&amp;nbsp;(white sweetclover) has invaded Alaskan glacial river floodplains. We measured cover and density of plant species and environmental variables along transects perpendicular to the Nenana, Matanuska, and Stikine Rivers to study interactions between&amp;nbsp;&lt;/span&gt;&lt;i&gt;M. albus&lt;/i&gt;&lt;span&gt;&amp;nbsp;and other plant species and to characterize the environment where it establishes.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Melilotus albus&lt;/i&gt;&lt;span&gt;&amp;nbsp;was a pioneer species on recently disturbed sites and did not persist into closed canopy forests. The relationships between&amp;nbsp;&lt;/span&gt;&lt;i&gt;M. albus&lt;/i&gt;&lt;span&gt;&amp;nbsp;cover and density and other species were site-specific.&lt;/span&gt;&lt;i&gt;Melilotus albus&lt;/i&gt;&lt;span&gt;&amp;nbsp;was negatively correlated with native species&amp;nbsp;&lt;/span&gt;&lt;i&gt;Elaeagnus commutata&lt;/i&gt;&lt;span&gt;&amp;nbsp;at the Nenana River, but not at the Matanuska River.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Melilotus albus&lt;/i&gt;&lt;span&gt;&amp;nbsp;was positively correlated with the exotic species&amp;nbsp;&lt;/span&gt;&lt;i&gt;Crepis tectorum&lt;/i&gt;&lt;span&gt;and&amp;nbsp;&lt;/span&gt;&lt;i&gt;Taraxacum officinale&lt;/i&gt;&lt;span&gt;&amp;nbsp;at the Matanuska River and&amp;nbsp;&lt;/span&gt;&lt;i&gt;T. officinale&lt;/i&gt;&lt;span&gt;&amp;nbsp;on the upper Stikine River. However, the high density of&amp;nbsp;&lt;/span&gt;&lt;i&gt;M. albus&lt;/i&gt;&lt;span&gt;&amp;nbsp;at a lower Stikine River site was negatively correlated with&amp;nbsp;&lt;/span&gt;&lt;i&gt;T. officinale&lt;/i&gt;&lt;span&gt;&amp;nbsp;and several native species including&amp;nbsp;&lt;/span&gt;&lt;i&gt;Lathyrus japonicus&lt;/i&gt;&lt;span&gt;&amp;nbsp;var.&amp;nbsp;&lt;/span&gt;&lt;i&gt;maritimus&lt;/i&gt;&lt;span&gt;&amp;nbsp;and&amp;nbsp;&lt;/span&gt;&lt;i&gt;Salix alaxensis&lt;/i&gt;&lt;span&gt;. Glacial river floodplains in Alaska are highly disturbed and are corridors for exotic plant species movement.&amp;nbsp;&lt;/span&gt;&lt;i&gt;Melilotus albus&lt;/i&gt;&lt;span&gt;&amp;nbsp;at moderate to low densities may facilitate establishment of exotic species, but at high densities can reduce the cover and density of both exotic and native species.&lt;/span&gt;&lt;/p&gt;</dc:description>
