Walnut Gulch Experimental Watershed site, station Shrubs and sparse grass vegetation zone in Walnut Gulch Watershed, study of plant cover of Parthenium incanum (mariola) 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 Walnut Gulch Experimental Watershed (WGE) contains plant cover of Parthenium incanum (mariola) measurements in percent units and were aggregated to a yearly timescale.

Data from: Population differentiation in common walnut (Juglans regia L.) across major parts of its native range - insights from molecular and morphometric data
Juglans regia is an economically highly important species for fruit and wood production in the warm temperate and subtropical zones of the Northern Hemisphere. Besides the natural influence of climatic and geomorphological barriers, its genetic structure has been strongly modified by humans and the population history is still unclear. For this reason, we investigated mainly natural walnut populations across the Eurasian continent on a molecular (44 populations, 581 trees) and morphometric level (23 populations, 1391 ripe nuts). Population genetic diversity and differentiation were examined by using 7 microsatellite loci. Morphometric characteristics of the nuts (mainly roundness index and nut density) were used to estimate trait variation and population differentiation. Highest allelic richness Rs12 = 7.05 was observed in a Pakistani and the lowest value Rs12 = 3.04 in a Kyrgyz population. The genetic differentiation among populations was high (FST = 0.217; RST = 0.530) indicating a strong phylogeographic pattern. While variation of the roundness index within single populations was high, this trait neither differentiated geographical regions nor was it associated to genetic clusters. Approximated QST based on this trait equalled FST, while approximated QST based on nut density considerably exceeded FST, indicating selection. Nut density was moderately correlated with altitude, latitude, and longitude, and differentiated populations according to their origin. Pakistani and Indian populations showed highest nut densities. These South Asian populations contain putatively ancestral nut forms, which probably have been lost in other populations as a consequence of human selection.
Data from: Early Cretaceous cyclostome bryozoans from the early to middle Albian of the Glen Rose and Walnut formations of Texas, USA
The Glen Rose and Walnut formations of southcentral and northcentral Texas comprise shallow-water carbonates deposited during the late Aptian to middle Albian on a carbonate platform. The formations are famous for their rich fossil faunas. Although bryozoans are absent in late Aptian sediments, they are frequently found encrusting bivalve shells from the early to middle Albian parts of these formations. Here, we describe the cyclostome bryozoan fauna, which includes six species; Stomatopora sp., Oncousoecia khirar n. sp., Reptomultisparsa mclemoreae n. sp., Hyporosopora keera n. sp., Mesonopora bernardwalteri n. sp. and ?Unicavea sp. Most cyclostomes are found encrusting rudist shells from Unit 2 of the Lower Member of the Glen Rose Formation and units 3 and 6 of the Upper Member of the Glen Rose Formation.
Genome-structural analyses support an allotetraploid origin of the walnut family from within Myricaceae and shared genome duplications reveal substitution rate variation
<p><span>In lineages of allopolyploid origin, entire parental subgenomes may coexist, with two or more sets of homoeologous chromosomes that differ in gene content and syntenic structure. Presence or absence of genes, and microsynteny along chromosomal blocks, can be used to differentiate subgenomes and can be coded as phylogenetic data. We assembled chromosome-level genomes of representative species across an ancient allopolyploid lineage, the walnut family (Juglandaceae)</span><span>, with <em>Myrica</em> and other Fagales as outgroups, and used genome-structural data to infer a phylogeny. </span><span>Microsynteny (with various collinear block sizes) and gene content analyses, using the dominant or recessive progenitor subgenomes or both, all yielded identical topologies that place <em>Engelhardia</em> (a SE Asian and Central American clade) with <em>Platycarya</em>, an </span><span>enigmatic monospecific taxon endemic in </span><span>East</span> <span>Asia</span><span>, but well-represented in the Paleocene-Eocene of North America and Europe. </span><span>Morphological studies including fossils also found the <em>Platycarya</em>/<em>Engelhardia</em> clade because of leaf architecture, floral morphology, and nut walls without lacunae, but DNA-alignment-based phylogenetics carried out here and in previous studies never detected this uniformly wind-dispersed clade, instead grouping <em>Platycarya</em> with <em>Carya</em> and <em>Juglans</em>. The novel analyses further reveal </span><span>the family's hybrid origin from extinct or unsampled progenitors nested within Myricaceae and that <em>Rhoiptelea</em> <em>chiliantha</em></span><span>, the Chinese sister species to all other Juglandaceae, </span><span>contains proportionally more genes related to DNA repair and evolved at a rate 2.6- to 3.5-times slower than the remaining species</span><span>. Our results have implications for the molecular clock hypothesis and suggest that genomic structure contains so-far undervalued phylogenetic signal</span><span>.</span></p>
