Data from: Genus-wide microsatellite primers for the goldenrods (Solidago; Asteraceae)

James B. Beck, John C. Semple, Justin M. Brull, Stacey L. Lance, Mai M. Phillips, Sara B. Hoot & Gretchen A. Meyer
Premise of the study: Microsatellite primers were developed for studies of polyploid evolution, ecological genetics, conservation genetics, and species delimitation in the genus Solidago. Methods and Results: Illumina sequencing of a shotgun library from S. gigantea identified ca. 1900 putative single-copy loci. Fourteen loci were subsequently shown to be amplifiable, single-copy, and variable in a broad range of Solidago species. Conclusions: The utility of these markers both across the genus and in herbarium specimens of...

Data from: Can asexuality confer a short term advantage? Investigating apparent biogeographic success in the apomictic triploid fern Myriopteris gracilis

David A. Wickell, Michael D. Windham, Xiaofei Wang, Stuart J. Macdonald & James B. Beck
Premise of the study: Although asexual taxa are generally seen as evolutionary dead ends, asexuality appears to provide a short-term benefit in some taxa, including a wider geographic distribution compared to sexual relatives. However, this may be an illusion created by multiple, morphologically cryptic, asexual lineages, each occupying a relatively small area. In this study we investigate the role of multiple lineages in the biogeography of Myriopteris gracilis Fée (Pteridaceae), a North American apomictic triploid...

Data from: Indoor air quality in California homes with code-required mechanical ventilation

Wanyu Chan, Yang-Seon Kim, William Delp, Iain Walker & Brett Singer
Data were collected in 70 detached houses built in 2011-2017 in compliance with the mechanical ventilation requirements of California’s building energy efficiency standards. Each home was monitored for a one-week period with windows closed and the central mechanical ventilation system operating. Pollutant measurements included time-resolved fine particulate matter (PM2.5) indoors and outdoors and formaldehyde and carbon dioxide (CO2) indoors. Time-integrated measurements were made for formaldehyde, NO2 and nitrogen oxides (NOX) indoors and outdoors. Operation of...

A basic ddRADseq two-enzyme protocol performs well in herbarium and silica-dried tissues across four genera

Ingrid Jordon-Thaden, James Beck, Catherine Rushworth, Michael Windham, Nicolas Diaz, Jason Cantley, Chris Martine & Carl Rothfels
Premise of the study: The ability to sequence genome-scale data from herbarium specimens would allow for the economical development of broad datasets with taxonomic and geographic sampling not otherwise possible. Here we evaluate the utility of a basic restriction site-associated DNA (ddRADseq) protocol with DNAs from four genera extracted from both silica-dried and herbarium tissue. Methods: DNAs from Draba, Boechera, Solidago, and Ilex were processed with a double-digest restriction-site associated DNA sequencing (ddRADseq) protocol. The...

Are Palmer’s elm-leaf goldenrod and the smooth elm-leaf goldenrod real? The Angiosperms353 kit provides within-species signal in Solidago ulmifolia s.l.

James Beck, Morgan Markley, Mackenzie Zielke, Justin Thomas, Haley Hale, Lindsay Wiliams & Matthew Johnson
Abstract — The genus Solidago represents a taxonomically challenging group due to its sheer number of species, putative hybridization, polyploidy, and shallow genetic divergence among species. Here we use a dataset obtained exclusively from herbarium specimens to evaluate the status of Solidago ulmifolia var. palmeri, a morphologically subtle taxon potentially confined to Alabama, Arkansas, Mississippi, and Missouri. A multivariate analysis of both discrete and continuous morphological data revealed no clear distinction between S. ulmifolia var....

Data from: Development of microsatellite markers for buffalograss (Buchloë dactyloides; Poaceae), a drought-tolerant turfgrass alternative

Jacob J. Hadle, Lauren A. Konrade, Rochelle R. Beasley, Stacey L. Lance, Kenneth L. Jones & James B. Beck
Premise of the study: Buchloë dactyloides is an important component of Great Plains prairies and a popular drought-tolerant turfgrass alternative in North America. This species comprises an autopolyploid series, and microsatellite primers were developed in order to understand the distribution of genetic variation among cytotypes and across its large geographic range. Methods and Results: Fifteen microsatellite loci were designed and successfully amplified in six B. dactyloides populations. Within-population genetic diversity was comparatively high, consistent with...

Data from: A rangewide herbarium-derived dataset indicates high levels of gene flow in black cherry (Prunus serotina)

Lauren Konrade, Joey Shaw & James Beck
Aim: Isolation by Distance (IBD) is a genetic pattern in which populations geographically closer to one another are more genetically similar to each other than populations which are farther apart. Black cherry (Prunus serotina Ehrh.) (Rosaceae) is a forest tree species widespread in eastern North America, and found sporadically in the southwestern United States, Mexico, and Guatemala. IBD has been studied in relatively few North American plant taxa, and no study has rigorously sampled across...

Data from: Botany is the root and the future of invasion biology

Nicholas Kooyers, Brittany Sutherland, Craig Barrett, James Beck, Michael McKain, Maribeth Latvis & Erin Sigel
This dataset was used to create Figure 1 within the linked On the Nature of Things article. The article describes how botanists have historically contributed to the field of invasion biology and why botanists should be an important contributor in the coming years. To make this point, we compared the relative frequencies of google ngrams containing the words 'invasive species', 'invasive plants', or the sum of frequencies from several different animal taxa including: ‘invasive insects’,...

Data from: Next-generation sampling: pairing genomics with herbarium specimens provides species-level signal in Solidago (Asteraceae)

James B. Beck & John C. Semple
Premise of the study: The ability to conduct species delimitation and phylogeny reconstruction with genomic data sets obtained exclusively from herbarium specimens would rapidly enhance our knowledge of large, taxonomically contentious plant genera. In this study, the utility of genotyping by sequencing is assessed in the notoriously difficult genus Solidago (Asteraceae) by attempting to obtain an informative single-nucleotide polymorphism data set from a set of specimens collected between 1970 and 2010. Methods: Reduced representation libraries...

Data from: Effects of apical meristem mining on plant fitness, architecture and flowering phenology in Cirsium altissimum (Asteracaeae)

Subodh Adhikari & F. Leland Russell
Premise of the study: Interactions that limit lifetime seed production have the potential to limit plant population sizes and drive adaptation through natural selection. Effects of insect herbivory to apical meristems (apical meristem mining) on lifetime seed production rarely have been quantified experimentally. We studied Cirsium altissimum (tall thistle), whose meristems are mined by Platyptilia carduidactyla (artichoke plume moth), to determine how apical damage affects plant maternal fitness and evaluate both direct and indirect mechanisms...

Data from: Adaptation to warmer climates by parallel functional evolution of CBF genes in Arabidopsis thaliana

J. Grey Monroe, Cullen McGovern, Jesse R. Lasky, Kelsi Grogan, James Beck & John K. McKay
The evolutionary processes and genetics underlying local adaptation at a specieswide level are largely unknown. Recent work has indicated that a frameshift mutation in a member of a family of transcription factors, C-repeat binding factors or CBFs, underlies local adaptation and freezing tolerance divergence between two European populations of Arabidopsis thaliana. To ask whether the specieswide evolution of CBF genes in Arabidopsis is consistent with local adaptation, we surveyed CBF variation from 477 wild accessions...

Data from: Arthropod assemblages on small mammal carrion of the Kansas Flint Hills: an ecological approach

Emmy Engasser, Rachel Stone & Mary Liz Jameson
Arthropods are critical to the decomposition of carrion, but little is known about the biodiversity of arthropods attracted to carrion or environmental factors that shape communities. This research described carrion beetle (Coleoptera: Silphidae) and dung beetle (Coleoptera: Scarabaeidae: Scarabaeinae and Aphodiinae) community assemblages on rat carrion across a full annual cycle (twelve contiguous months, 2016-2017). Abiotic data (light availability, wind speed, soil surface humidity, soil surface temperature) complement the beetle biodiversity data. Together, these data...
