This dataset enumerates the number of geocoded tweets captured in geographic rectangular bounding boxes around the metropolitan statistical areas (MSAs) defined for 49 American cities, during a four-week period in 2012 (between April and June), through the Twitter Streaming API.

These data are the result of a multi-step process aimed at enriching BIBFRAME RDF with linked data. The process takes in an initial MARC XML file, transforms it to BIBFRAME RDF/XML, and then four separate python files corresponding to the BIBFRAME 1.0 model (Work, Instance, Annotation, and Authority) are run over the BIBFRAME RDF/XML output. The input and outputs of each step are included in this data set. Input file types include the CSV; MARC XML; and Master RDF/XML Files. The CSV contain bibliographic identifiers to e-books. From CSVs a set of MARC XML are generated. The MARC XML are utilized to produce the Master RDF file set. The major outputs of the enrichment code produce BIBFRAME linked data as Annotation RDF, Instance RDF, Work RDF, and Authority RDF.

Datasets and R scripts relating to the manuscript "Ecological characteristics and in situ genetic associations for yield-component traits of wild Miscanthus from eastern Russia" published in Annals of Botany, 10.1093/aob/mcw137. Field data, including collection locations, physical and ecological information for each location, and plant phenotypes relating to biomass are included. Genetic data in this repository include single nucleotide polymorphisms (SNPs) derived from restriction site-associated DNA sequencing (RAD-seq), as well as plastid microsatellites. A file is also included listing the DNA sequences of all RAD-seq markers generated to-date by the Sacks lab, including those from this publication.

This dataset was extracted from a set of metadata files harvested from the DataCite metadata store (https://search.datacite.org/ui) during December 2015. Metadata records for items with a resourceType of dataset were collected. 1,647,949 total records were collected. This dataset contains three files: 1) readme.txt: A readme file. 2) version-results.csv: A CSV file containing three columns: DOI, DOI prefix, and version text contents 3) version-counts.csv: A CSV file containing counts for unique version text content values.
