Do Loss Aversion and the Ownership Effect Bias Content Validation Procedures?

Vanessa Svihla & Amber Gallup
In making validity arguments, a central consideration is whether the instrument fairly and adequately covers intended content, and this is often evaluated by experts. While common procedures exist for quantitatively assessing this, the effect of loss aversion—a cognitive bias that would predict a tendency to retain items—on these procedures has not been investigated. For more novel constructs, experts are typically drawn from adjacent domains. In such cases, a related cognitive bias, the ownership effect, would...

Future fire-driven landscape changes along a southwestern US elevation gradient

Matthew Hurteau & Cecile Remy
Over the 21st century, the combined effects of increased fire activity and climate changes are expected to altered forest composition and structure in many ecosystems by changing post-fire successional trajectories and recovery. The southwestern US mountains encompass varied vegetation types and species according to elevation which do not respond the same to changing climate and fire regime. Moreover, fire exclusion applied during the early 20th century has altered forest structure and fuel loads compared to...

Disentangling lousy relationships: Comparative phylogenomics of two sucking louse lineages parasitizing chipmunks

Kayce Bell, Julie M. Allen, Kevin P. Johnson, John R. Demboski & Joseph A. Cook
The evolution of obligate parasites is often interpreted in light of their hosts’ evolutionary history. An expanded approach is to examine the histories of multiple lineages of parasites that inhabit similar environments on a particular host lineage. Western North American chipmunks (genus Tamias) have a broad distribution, a history of divergence with gene flow, and host two species of sucking lice (Anoplura), Hoplopleura arboricola and Neohaematopinus pacificus. From total genomic sequencing, we obtained sequences of...

Complex histories of gene flow and a mitochondrial capture event in a non-sister pair of bird

Ethan Gyllenhaal, Michael Andersen, Jenna McCullough, Xena Mapel, Tri Haryoko, Knud Jønsson & Leo Joseph
Hybridization, introgression, and reciprocal gene flow during speciation, specifically the generation of mitonuclear discordance, are increasingly observed as parts of the speciation process. Genomic approaches provide insight into where, when, and how adaptation operates during and after speciation and can measure historical and modern introgression. Whether adaptive or neutral in origin, hybridization can cause mitonuclear discordance by placing the mitochondrial genome of one species (or population) in the nuclear background of another species. The latter,...

Telemetry validated nitrogen stable isotope clocks identify ocean-to-estuarine habitat shifts in mobile organisms

Oliver Shipley, Alisa Newton, Michael Frisk, Gregory Henkes, Jake LaBelle, Merry Camhi, Michael Hyatt, Hans Walters & Jill Olin
1. Throughout their life history, many animals transition among heterogenous environments to facilitate behaviors such as reproduction, foraging, and predator avoidance. The dynamic environmental and biological conditions experienced by mobile species are integrated in the chemical composition of their tissues, providing retrospective insight into movement. 2. Here, we present a unique nitrogen stable isotope clocks (‘isotopic clocks’), which integrate tissue turnover rates, consumer stable isotope ratios, and habitat-specific isotope baselines and can be used to...

Functional changes in fortified places: Strategy and defensive architecture in the Medieval and Early Modern Era

Scott Kirk & Evan Sternberg
Data for Scott Kirk's Doctoral Dissertation. Dissertation Abstract: Defined as fortified elite Houses, castles are a cross-cultural phenomenon, best understood by pairing Niche Construction Theory (NCT) with the Lévi-Straussian concept of the House. NCT can be thought of as a theory of the built environment, thus the material configuration of castles and their placement on the landscape reflect elite socio-cultural requirements. My dissertation asks: How do changes in castle morphology and landscape placement reflect broad...

Still time for action: genetic conservation of imperiled South Canadian River fishes, Arkansas River Shiner (Notropis girardi), Peppered Chub (Macrhybopsis tetranema) and Plains Minnow (Hybognathus placitus)

Megan Osborne, Joanna Hatt, Eliza Gilbert & Stephen Davenport
Pelagic broadcast spawning cyprinids have declined throughout the North American Great Plains because of adverse habitat changes caused by river fragmentation and altered flow regimes. Despite losses elsewhere, a 218-river kilometer section of the South Canadian River maintains three of these imperiled species: Arkansas River Shiner, Peppered Chub and Plains Minnow. The objective of this study was to determine if species occupying the same river stretch and hence a shared environment, exhibit the same trajectory...

Elucidating gene expression adaptation of phylogenetically divergent coral holobionts under heat stress

Viridiana Avila-Magaña, Bishoy Kamel, Michael DeSalvo, Kelly Gómez-Campo, Susana Enríquez, Hiroaki Kitano, Rori Rohlfs, Roberto Iglesias-Prieto & Mónica Medina
As coral reefs struggle to survive under climate change, it is crucial to know whether they have the capacity to withstand changing conditions, particularly increasing seawater temperatures. Thermal tolerance requires the integrative response of the different components of the coral holobiont (coral host, algal photosymbiont, and associated microbiome). Here, using a controlled thermal stress experiment across three divergent Caribbean coral species, we attempt to dissect holobiont member metatranscriptome responses from coral taxa with different sensitivities...

Supporting data for: Post-fire early successional vegetation buffers surface microclimate and increases survival of planted conifer seedlings in the southwestern United States

Matthew Hurteau & Joseph Crockett
Climate change and fire-exclusion have increased the flammability of western US forests, leading to forest cover loss when wildfires occur under severe weather conditions. Increasingly large high-severity burn patches are a limitation to natural regeneration because of dispersal distance, increasing the chance that these areas are converted to non-forest. Post-fire planting can overcome dispersal limitations, yet warmer and drier post-fire conditions can still limit survival. Early successional vegetation can alter surface microclimate; however, it is...

A lightweight backpack harness for tracking hummingbirds

Jessie L. Williamson & Christopher C. Witt
Hummingbirds and other lightweight bird species are challenging to track because they have limited capacity to carry devices for data-logging. We present a simple and customizable three-loop ‘backpack’ harness for studying hummingbird migration and movement, with step-by-step instructions for harness construction and attachment. The harness has negligible weight and cost (< $0.50 USD/each), is easy for a single person to make and apply in the field, and it requires no complicated setup or equipment. We...

Population connectivity across a highly fragmented distribution: Phylogeography of the Chalcophaps doves

Devon DeRaad, Joseph Manthey, Emily Ostrow, Lucas DeCicco, Michael Andersen, Peter Hosner, Hannah Shult, Leo Joseph, John Dumbacher & Robert Moyle
Chalcophaps is a morphologically conserved genus of ground-walking doves distributed from India to mainland China, south to Australia, and across the western Pacific to Vanuatu. Here, we reconstruct the evolutionary history of this genus using DNA sequence data from two nuclear genes and one mitochondrial gene, sampled from throughout the geographic range of Chalcophaps. We find support for three major evolutionary lineages in our phylogenetic reconstruction, each corresponding to the three currently recognized Chalcophaps species....

Contrasting patterns of phylogenetic diversity and alpine specialization across the alpine flora of the American mountain range system

Hector Fox Figueroa, Hannah E. Marx, Maria Beatriz De Souza Cortez, Charles J. Grady, Nicholas Engle-Wrye, Jim Beach, Aimee Stewart, Ryan A. Folk, Douglas E. Soltis, Pamela S. Soltis & Stephen A. Smith
Although mountainous habitats contribute substantially to global biodiversity, comparatively little is known about biogeographic patterns of distributions of alpine species across multiple mountain ranges. Here, we present a detailed analysis of the distributions and phylogenetic affinities of alpine seed plant lineages across North, Central, and South American mountain systems. Using a comprehensive dataset that characterized the elevational niches of American seed plants in a continuously valued way, we were able to quantitatively investigate how the...

Gila Trout neutral and outlier SNP genotype matrices

David Camak, Megan Osborne & Thomas Turner
Many salmonid species exist in highly structured and isolated populations, and are susceptible to habitat fragmentation and disturbances. Gila Trout (Oncorhynchus gilae) is a threatened species found in the Southwestern United States, and is managed to preserve relict populations (i.e., lineages) distributed across a fragmented landscape. We evaluated genomic variation within and among remaining lineages of Gila Trout using RADseq to assess how drift and selection have structured populations using neutral and outlier loci. We...

Analysis of paralogs in target enrichment data pinpoints multiple ancient polyploidy events in Alchemilla s.l. (Rosaceae)

Diego F. Morales-Briones, Berit Gehrke, Chien-Hsun Huang, Aaron Liston, Hong Ma, Hannah Marx, David Tank & Ya Yang
Target enrichment is becoming increasingly popular for phylogenomic studies. Although baits for enrichment are typically designed to target single-copy genes, paralogs are often recovered with increased sequencing depth, sometimes from a significant proportion of loci, especially in groups experiencing whole-genome duplication (WGD) events. Common approaches for processing paralogs in target enrichment data sets include random selection, manual pruning, and mainly, the removal of entire genes that show any evidence of paralogy. These approaches are prone...

Data from: Signatures of north-eastern expansion and multiple refugia: Genomic phylogeography of the Pine Barrens Treefrog, Hyla andersonii (Anura: Hylidae)

Alexa Warwick, Lisa Barrow, Megan Smith, D. Bruce Means, Alan Lemmon & Emily Lemmon
Range fragmentation poses challenges for species persistence over time and may be caused by both historical and contemporary processes. We combined genomic data, phylogeographic model testing, and paleoclimate niche modeling to infer the evolutionary history of the Pine Barrens Treefrog (Hyla andersonii), a seepage bog specialist, in eastern North America to better understand the historical context of its fragmented distribution. We sampled H. andersonii populations across the three disjunct regions of the species’ range: Alabama/Florida...

Supporting data for Climate-driven tree mortality and fuel aridity increase wildfire's potential sensible heat flux

Matthew Hurteau & Goodwin Marissa
Wildfire is capable of rapidly releasing the energy stored in forests, with the amount of water in live and dead biomass acting as a regulator on the amount and rate of energy release. Here we used temperature and fuel moisture data to examine climate-driven changes in fuel moisture content over the past three decades. We then calculated the changes in energy release (energy release component and fire radiant energy) for two forests that experienced drought...

Do tradeoffs govern plant species responses to different global change treatments?

J. Adam Langley, Emily Grman, Kevin Wilcox, Meghan Avolio, Kimberly Komatsu, Scott Collins, Sally Koerner, Melinda Smith, Andrew Baldwin, William Bowman, Nona Chiariello, Anu Eskelinen, Harry Harmens, Mark Hovenden, Kari Klanderud, Rebecca McCulley, Vladimir Onipchenko, Clare Robinson & Katharine Suding
Plants are subject to tradeoffs among growth strategies such that adaptations for optimal growth in one condition can preclude optimal growth in another. Thus, we hypothesized that the response of plant species abundance to one global change treatment would relate inversely to the response to a second treatment, particularly for treatment combinations that accentuate distinct traits. To address this hypothesis, we examined plant species abundances in 39 global change experiments manipulating CO2, nitrogen, phosphorus, water,...

Quantifying niche similarity among new world seed plants--Species Distribution Models (SDMs) & associated metadata

Hector Figueroa, Hannah Marx, CJ Grady, Jim Beach, Ryan Folk, Douglas Soltis, Pamela Soltis, Aimee Stewart & Stephen Smith
Niche shift and conservatism are often framed as mutually exclusive. However, both processes could contribute to biodiversity patterns. We tested this expectation by quantifying the degree of climatic niche similarity among New World seed plants. To incorporate the biological reality that species experience varied abiotic conditions across their range, we assembled distribution models and used these to characterize temperature, precipitation, and elevation niches for species as continuously-valued distributions. We then quantified niche similarity (distributional overlap)...
