Invasive buffel grass (Cenchrus ciliaris) increases water stress and reduces growth of native foothills palo verde (Parkinsonia microphylla) seedlings in pot experiments
Although buffel grass (Cenchrus ciliaris) invasions on several continents have significant ecological impacts, little information is available on its effect on seedling emergence and establishment of native vegetation. In highly impacted areas of the Sonoran Desert of North America, perennial plants are particularly vulnerable during their seedling stage. We studied the impact of buffel grass on the emergence, survival, and water stress in the seedlings of a locally dominant native tree, the foothills palo verde (Parkinsonia microphylla), using two pot experiments. In the first experiment, we compared the germination, growth, and survival of concentric rings of palo verde seedlings around mature individuals of buffel grass, a native shrub of a similar diameter and height to buffel grass, or in a pot with bare soil. In the second experiment, we compared the competitive effects of buffel grass seedlings on palo verde seedlings with the effects of conspecific seedlings, again using germination, growth, and survival as metrics. We followed up both experiments by quantifying the ratio of stable carbon isotopes in the tissues of the palo verde seedlings, which can be an indicator of water stress. We found evidence of relatively greater water stress in palo verde seedlings grown with buffel grass seedlings in pots than those grown with no competitor, and reduced survival of palo verde seedlings when grown with mature buffel grass. Our results highlight the need for more manipulative studies of density to improve mechanistic understanding of population dynamics, and to forecast how populations and communities will respond in the long term to perturbations such as invasion.

Cedar Creek Ecosystem Science Reserve site, station Old Field 26 at Cedar Creek, study of plant cover of Cenchrus longispinus in units of percent 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 Cedar Creek Ecosystem Science Reserve (CDR) contains plant cover of Cenchrus longispinus measurements in percent units and were aggregated to a yearly timescale.

Surveying the genome and constructing a high-density genetic map of napiergrass (Cenchrus purpureus Schumach)
<p>Napiergrass (Cenchrus purpureus Schumach) is a tropical forage grass and a promising lignocellulosic biofuel feedstock due to its high biomass yield, persistence, and nutritive value. However, its utilization for breeding has lagged behind other crops due to limited genetic and genomic resources. In this study, next-generation sequencing was frst used to survey the genome of napiergrass. Napiergrass sequences displayed high synteny to the pearl millet genome and showed expansions in the pearl millet genome along with genomic rearrangements between the two genomes. An average repeat content of 27.5% was observed in napiergrass including 5,339 simple sequence repeats (SSRs). Furthermore, to construct a high-density genetic map of napiergrass, genotyping-by-sequencing (GBS) was employed in a bi-parental population of 185 F1 hybrids. A total of 512 million high quality reads were generated and 287,093 SNPs were called by using multiple de-novo and reference-based SNP callers. Single dose SNPs were used to construct the frst high-density linkage map that resulted in 1,913 SNPs mapped to 14 linkage groups, spanning a length of 1,410cM and a density of 1 marker per 0.73cM. This map can be used for many further genetic and genomic studies in napiergrass and related species.</p> <p><strong>Genetic map files for Elephant grass genetic map.</strong><br> Surveying the genome and constructing a high-density genetic map of napiergrass (Cenchrus purpureus Schumach)</p> <p><strong># Marker files:</strong><br> Sex averaged map: map_NG_final_geneticmap_1913.txt<br> Female map: map_female_selected899_lm.txt<br> Male map: map_male_selected1073_nn.txt </p> <p><strong># Sequence and locus information.</strong><br> All reference based pipelines used the pearl millet genome v1 as explained in the manuscript.
