2012 LTER ASM - Pattern and control of primary production http://asm2012.lternet.edu/taxonomy/term/125/0 Plant growth in most ecosystems forms the base or “primary” component of the food web. The amount and type of plant growth in an ecosystem helps to determine the amount and kind of animals (or “secondary” productivity) that can survive there. en Spatial and inter-annual variability of net community productivity in the western Antarctica Peninsula region http://asm2012.lternet.edu/content/spatial-and-inter-annual-variability-net-community-productivity-western-antarctica-peninsula <div class="field field-type-computed field-field-poster-number"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Poster Number:&nbsp;</div> 399 </div> </div> </div> <div class="field field-type-userreference field-field-poster-presenter"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Presenter/Primary Author:&nbsp;</div> <a href="http://asm2012.lternet.edu/users/khuang" title="View user profile.">Kuan Huang</a> </div> </div> </div> <div class="field field-type-text field-field-poster-authors"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Co-Authors:&nbsp;</div> Hugh Ducklow </div> <div class="field-item even"> <div class="field-label-inline"> Co-Authors:&nbsp;</div> Oscar Schofield </div> <div class="field-item odd"> <div class="field-label-inline"> Co-Authors:&nbsp;</div> Michael Bender </div> </div> </div> <p>&nbsp;</p><div class="field field-type-text field-field-poster-student-poster"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Student Poster:&nbsp;</div> Yes </div> </div> </div> <p><a href="http://asm2012.lternet.edu/content/spatial-and-inter-annual-variability-net-community-productivity-western-antarctica-peninsula" target="_blank">read more</a></p> Site Science Primary Production PAL Pattern and control of primary production Oceanography Sat, 08 Sep 2012 00:16:18 +0000 khuang 574 at http://asm2012.lternet.edu Increased Connectivity in a Polar Desert Resulting from Climate Warming: McMurdo Dry Valley LTER Program http://asm2012.lternet.edu/content/increased-connectivity-polar-desert-resulting-climate-warming-mcmurdo-dry-valley-lter-progra <div class="field field-type-computed field-field-poster-number"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Poster Number:&nbsp;</div> 392 </div> </div> </div> <div class="field field-type-userreference field-field-poster-presenter"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Presenter/Primary Author:&nbsp;</div> <a href="http://asm2012.lternet.edu/users/dmcknight" title="View user profile.">Diane McKnight</a> </div> </div> </div> <p>The McMurdo Dry Valleys (MDV) is a polar desert on the coast of East Antarctica, a region that has not yet experienced the climate warming that is now occurring elsewhere.</p><p><a href="http://asm2012.lternet.edu/content/increased-connectivity-polar-desert-resulting-climate-warming-mcmurdo-dry-valley-lter-progra" target="_blank">read more</a></p> Site Science Core Research Areas MCM Pattern and control of primary production Thu, 06 Sep 2012 02:50:17 +0000 dmcknight 564 at http://asm2012.lternet.edu Detecting the sensitivity of desert herbaceous plant responses to co-occurring atmospheric compounds http://asm2012.lternet.edu/content/detecting-sensitivity-desert-herbaceous-plant-responses-co-occurring-atmospheric-compounds <div class="field field-type-computed field-field-poster-number"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Poster Number:&nbsp;</div> 379 </div> </div> </div> <div class="field field-type-userreference field-field-poster-presenter"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Presenter/Primary Author:&nbsp;</div> <a href="http://asm2012.lternet.edu/users/ecook" title="View user profile.">Elizabeth Cook</a> </div> </div> </div> <div class="field field-type-text field-field-poster-authors"> <div class="field-items"> <div class="field-item odd"> <div class="field-label-inline-first"> Co-Authors:&nbsp;</div> Sharon J Hall </div> </div> </div> <p>Cities occupy a small land area globally, yet atmospheric compounds generated from human-dominated ecosystems have significant impacts on protected lands within and beyond urban boundaries.&nbsp;
