Part of a training dataset of scanned herbarium specimens. The data paper and a summary landing page will be published on Zenodo as it gets published.<br><br>Content of this deposition:<br><br>- A JSON-LD datafile listing the label data associated with this herbarium specimen. The Darwin and Dublin Core data standards are used for most values.<br>- A JPEG image file of the scanned herbarium sheet.<br>- Two PNG files containing segmented image overlays of the scanned herbarium sheet. The _all extension indicates that all labels, color charts and pieces of text have received a different color against a black background color. The _sel extension indicates that these elements are white if they're barcode labels, yellow if they're color charts and red if they're anything else.

H. J. Andrews Experimental Forest site, station Andrews Watershed 1, study of plant cover of Elymus glaucus 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 Elymus glaucus measurements in percent units and were aggregated to a yearly timescale.
Data from: A population genetic window into the past and future of the walleye Sander vitreus: Relation to historic walleye and the extinct "blue pike" S. v. "glaucus"
Background: Conserving genetic diversity and local adaptations are management priorities for wild populations of exploited species, which increasingly are subject to climate change, habitat loss, and pollution. These constitute growing concerns for the walleye Sander vitreus, an ecologically and economically valuable North American temperate fish with large Laurentian Great Lakes' fisheries. This study compares genetic diversity and divergence patterns across its widespread native range using mitochondrial (mt) DNA control region sequences and nine nuclear DNA microsatellite (μsat) loci, examining historic and contemporary influences. We analyze the genetic and morphological characters of a putative endemic variant– "blue pike" S. v. "glaucus" –described from Lakes Erie and Ontario, which became extinct. Walleye with turquoise-colored mucus are evaluated, since some have questioned whether these are related to the "blue pike". Results: Walleye populations are distinguished by significant considerable genetic divergence (mean FST mtDNA=0.32±0.01, μsat=0.13±0.00) and substantial diversity across their range (mean heterozygosity mtDNA=0.53±0.02, μsat=0.68±0.03). Southern populations markedly differ, possessing unique haplotypes and alleles, especially the . The Ohio/New River population that housespossesses the most pronounced divergence and the oldest haplotype. Northerly formerly glaciated populations have greatest diversity in Lake Erie (mean heterozygosity mtDNA=0.79±0.00, μsat=0.72±0.01). Genetic diversity was much less in historic Lake Erie samples from 1923–1949 (mean heterozygosity mtDNA=0.05±0.01, μsat=0.47±0.06) than today. The historic "blue pike" had no unique haplotypes/alleles and there is no evidence that it comprised a separate taxon from walleye. Turquoise mucus walleye also show no genetic differentiation from other sympatric walleye and no correspondence to the "blue pike". Conclusions: Contemporary walleye populations possess high levels of genetic diversity and divergence, despite habitat degradation and exploitation. Genetic and previously published tagging data indicate that natal homing and spawning site philopatry led to population structure. Population patterns were shaped by climate change and drainage connections, with northern ones tracing to post-glacial recolonization. Southerly populations possess unique alleles and may provide an important future genetic reservoir. Allelic frequencies of Lake Erie walleye from ~70–90 years ago significantly differed from today, suggesting population recovery after extensive habitat loss, pollution, and exploitation. The historic "blue pike" was indistinguishable from walleye, indicating that taxonomic designation is not warranted.
