  <dc:description>&lt;ul class="plain-list"&gt;&lt;li&gt;&lt;p&gt;A common response of plants to elevated atmospheric CO&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;concentration (CO&lt;sub&gt;2&lt;/sub&gt;) is decreased leaf conductance. Consequently, leaf temperature is predicted to increase under elevated CO&lt;sub&gt;2&lt;/sub&gt;.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;Diurnal patterns of leaf conductance and temperature were measured for three desert perennials, the C&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;shrub&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Larrea tridentata&lt;/i&gt;, C&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;tussock grass&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Achnatherum hymenoides&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and C&lt;sub&gt;4&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;tussock grass&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Pleuraphis rigida&lt;/i&gt;, at the Nevada Desert FACE facility. Measurements were made on ambient and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;c&lt;/i&gt;. 550&amp;nbsp;µmol mol&lt;sup&gt;−1&lt;/sup&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;CO&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;plots through both a wet and dry year.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;Reductions in conductance were 35%, 20% and 13% for&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Pleuraphis&lt;/i&gt;,&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Achnatherum&lt;/i&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;and&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Larrea&lt;/i&gt;, respectively. Decreased conductance occurred throughout the day only for&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;Pleuraphis&lt;/i&gt;. Both C&lt;sub&gt;3&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;species had smaller CO&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;effects during dry periods than wet. Leaf temperature did not differ significantly between elevated and ambient CO&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;for any species. Comparisons of blower-control and nonring plots indicated that the FACE apparatus did not confound our results.&lt;/p&gt;&lt;/li&gt;&lt;li&gt;&lt;p&gt;All three species exhibited decreased leaf conductance under elevated CO&lt;sub&gt;2&lt;/sub&gt;, although reductions were not uniform during the day or among years. Nonetheless, leaf energy balance was only minimally changed for these microphyllous desert perennials.&lt;/p&gt;&lt;/li&gt;&lt;/ul&gt;</dc:description>
