<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:"Calibri",sans-serif"><span>Title: How will dryland nitrogen cycling respond to global change
factors? <span></span></span></p>
<p class="MsoNormal" style="margin:0in 0in 8pt;line-height:107%;font-size:11pt;font-family:"Calibri",sans-serif"><span>Abstract: Despite exhibiting characteristics of nitrogen (N) limitation,
drylands can have high rates of N loss when biological N demand does not
correspond with periods of high N availability. For example, large pulses of N
can be lost to the atmosphere following rain events when rapid microbial
processes export N before plants can assimilate it. This represents an
important loss of N from dryland ecosystems, where biological productivity is
already N limited, and can also contribute to regional air quality and the
greenhouse effect. Human activity can affect the processes responsible for
dryland N trace gas production through multiple factors of global change,
including N deposition and altered precipitation regimes. In this talk, I will
explore the following questions: 1) what processes produce nitric oxide (NO) and
nitrous oxide (N<sub>2</sub>O) from dry soils? and 2) how will these processes
respond to factors of global change? To answer these questions, I will present
results from field experiments conducted across a N deposition gradient and in
response to experimentally altered precipitation in Southern California
drylands.<span> </span><b><span></span></b></span></p>

Krichels is a postdoctoral researcher of Environmental Sciences at the
University of California, Riverside. He has a Ph.D. in Ecology, Evolution, and
Conservation Biology from the University of Illinois at Urbana Champaign and
B.A.s in Environmental Studies and Biology from Oberlin College. His research
explores how factors of global change affect the functioning of managed and
natural ecosystems and how these responses feedback to alter future global
change. Currently, he is using stable isotope and molecular techniques to study
how nitrogen deposition and altered precipitation regimes affect nitrogen
cycling in dryland soils, with consequences for regional air quality and
Earth’s climate. <b><span></span></b></span></p>
