  <dc:description>&lt;p&gt;&lt;span&gt;Several decades of research in alpine ecosystems have demonstrated links among the critical zone, hydrologic response, and the fate of elevated atmospheric nitrogen (N) deposition. Less research has occurred in mid-elevation forests, which may be important for retaining atmospheric N deposition. To explore the fate of N in the montane zone, we conducted plot-scale experimental rainfall events across a north–south transect within a catchment of the Boulder Creek Critical Zone Observatory. Rainfall events mimicked relatively common storms (20–50% annual exceedance probability) and were labeled with &lt;/span&gt;&lt;sup&gt;15&lt;/sup&gt;&lt;span&gt;N-nitrate (&lt;/span&gt;&lt;span id="IEq1" class="InlineEquation"&gt;&lt;span id="MathJax-Element-1-Frame" class="MathJax" data-mathml="&lt;math xmlns=&amp;quot;http://www.w3.org/1998/Math/MathML&amp;quot;&gt;&lt;msubsup&gt;&lt;mrow class=&amp;quot;MJX-TeXAtom-ORD&amp;quot;&gt;&lt;mtext&gt;NO&lt;/mtext&gt;&lt;/mrow&gt;&lt;mrow class=&amp;quot;MJX-TeXAtom-ORD&amp;quot;&gt;&lt;mn&gt;3&lt;/mn&gt;&lt;/mrow&gt;&lt;mrow class=&amp;quot;MJX-TeXAtom-ORD&amp;quot;&gt;&lt;mo&gt;&amp;amp;#x2212;&lt;/mo&gt;&lt;/mrow&gt;&lt;/msubsup&gt;&lt;/math&gt;"&gt;&lt;span id="MathJax-Span-1" class="math"&gt;&lt;span&gt;&lt;span&gt;&lt;span id="MathJax-Span-2" class="mrow"&gt;&lt;span id="MathJax-Span-3" class="msubsup"&gt;&lt;span&gt;&lt;span&gt;&lt;span id="MathJax-Span-4" class="texatom"&gt;&lt;span id="MathJax-Span-5" class="mrow"&gt;&lt;span id="MathJax-Span-6" class="mtext"&gt;NO&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span&gt;&lt;span id="MathJax-Span-7" class="texatom"&gt;&lt;span id="MathJax-Span-8" class="mrow"&gt;&lt;span id="MathJax-Span-9" class="mo"&gt;−&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span&gt;&lt;span id="MathJax-Span-10" class="texatom"&gt;&lt;span id="MathJax-Span-11" class="mrow"&gt;&lt;span id="MathJax-Span-12" class="mn"&gt;3&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span class="MJX_Assistive_MathML"&gt;NO3−&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span&gt;) and lithium bromide tracers.
