Data from: A new species and introgression in eastern Asian hemlocks (Pinaceae: Tsuga)
Species delimitation in Pinaceae is often challenged by limited morphological differentiation and introgression. In Tsuga (hemlocks), species delimitation has been most challenging among northeastern Asian taxa, where the species are weakly marked morphologically and range in number from three to five in previous studies. Two low-copy nuclear four-coumarase-ligase (4CL) genes andmorphology strongly support a clade of the Japanese endemic T. diversifolia and T. sieboldii from Japan and Ulleung island (Ulleungdo) in Korea. This clade is here referred to as the oceanic hemlocks. 4CL strongly supports a sister-group relationship of the widespread northeastern Asian T. chinensis and eastern North American T. caroliniana. In contrast, chloroplast genomes, which are markedly reduced in Tsuga and relatives, strongly support Japanese T. sieboldii as sister to T. chinensis and moderately support T. caroliniana as sister to a clade of T. diversifolia and hemlocks fromUlleungdo. These divergent topologies suggest chloroplast capture of T. chinensis by Japanese T. sieboldii. Ulleungdo hemlocks are distinct from other northeastern Asian species in leaf and cone morphology and phenologically in common-garden observations. We therefore describe these hemlocks as a new species, T. ulleungensis.
Data from: The phyllosphere microbiome in Tsuga canadensis: Possible relationships with resistance to Adelges tsugae and effects of the pesticide dinotefuran
<p>Eastern hemlock (<em>Tsuga canadensis</em>) is an important forest tree species in North America. It currently faces threats from invasive insects; primarily hemlock woolly adelgid (HWA -<em> Adelges tsugae</em>)<em> </em>and elongate hemlock scale (EHS - <em>Fiorinia externa</em><em>). </em>Both insect species are native to Asia with Tsuga species in the native range typically resistant to the damage they cause. We conducted a study of the phyllosphere microbiome of two hemlock species native to North America and susceptible to HWA (<em>T. canadensis</em> and <em>T. caroliniana</em>), and two species native to Asia and resistant to HWA (<em>T. chinensis</em> and <em>T. diversifolia</em>). The files for this experiment are labelled "Hemlock Microbiome." Since pesticide application is often used to treat North American hemlock species impacted by HWA and EHS, we also examined how the pesticide dinotefuran affected the microbiome and overall plant physiology of <em>T. canadensis</em>. The files for this experiment are labelled "Hemlock Dinotefuran."</p> <p>Included here are zOTU tables for fungi and bacteria and the taxonomic matches for each zOTU from both experiments, as well as the codes used in the programs USEARCH and Cutadapt to generate these data tables. (Note that raw sequence reads are publicly available in the Sequence Read Archive under BioProject number PRJNA1052676.) In addition, R scripts that show 1) how these data were analyzed with PERMANOVA and PERMDISP and visualized with PCoA in the R package vegan, including sequence read normalization in the R package DESeq2, 2) how the relative abundance of the top taxa were graphed in the R package phyloseq, and 3) indicator species analysis in the R package indicspecies are included. Finally, the raw data for plant physiology measurements are also included, along with the R script on how these data were analyzed with ANOVAs.</p>

H. J. Andrews Experimental Forest site, station Andrews Watershed 1, study of plant cover of Tsuga heterophylla 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 H. J. Andrews Experimental Forest (AND) contains plant cover of Tsuga heterophylla measurements in percent units and were aggregated to a yearly timescale.
