Kellogg Biological Station site, station Kellogg Biological Station, study of aboveground net primary productivity of Stellaria media in units of gramsPerMeterSquaredPerYear on a yearly timescale
The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Kellogg Biological Station (KBS) contains aboveground net primary productivity of Stellaria media measurements in gramsPerMeterSquaredPerYear units and were aggregated to a yearly timescale.

Stellaria motuoensis (Caryophyllaceae), a new species from Xizang, China
<p><em><span>Stellaria motuoensis</span></em><span> sp. nov. (Caryophyllaceae) is described and illustrated as a new species from Xizang of China on the basis of both morphological and molecular evidence.</span> <span>Phylogenetic analysis based on ITS sequence data show that </span><em><span>S. motuoensis</span></em><span> is closely related to <em>S. monosperma</em>. Morphological observation has shown that </span><em><span>S. motuoensis</span></em><span> is most similar to <em>S. monosperma</em> var. <em>paniculata</em>, but readily differs by its bisexual flower with no petals (versus bisexual or unisexual with petals 5), five stamens (versus 5 or 10), filiform roots (versus fusiform, thick, fleshy), terete stem (versus quadrangular),</span> <span>stems glabrous basally, pubescent apically (versus glandular pubescent, with 1 or 2 rows of hairs above), leaves glabrous (versus pubescent).</span></p>
