Digital Appendix of Masters Thesis \"Constraining deformation mechanisms of damage zones: A case study of the shallow San Andreas Fault at Elizabeth Lake, Southern California\"

James Evans & Caroline Studnicky
We performed macroscopic, optical petrographic, scanning electron microscopy, and geochemical analyses on rock core acquired across the San Andreas Fault at Elizabeth Lake, California, in order to understand the distribution and accommodation of fault-related slip and energy within the shallow damage zone of this continental scale strike-slip fault. We characterized the deformation structures, alteration textures, and elemental variabilities to constrain the properties of the uppermost ~2 km fault-related damage zone at this site. We identified...

Data from: Yellow Air Day Advisory Study

Arthur J. Caplan
Using a dataset consisting of daily vehicle trips, PM2.5 concentrations, along with a host of climactic control variables, we test the hypothesis that “yellow air day” advisories provided by the Utah Division of Air Quality resulted in subsequent reductions in vehicle trips taken during northern Utah’s winter-inversion seasons in the early 2000s. Winter inversions occur in northern Utah when climactic conditions are such that PM2.5 concentrations (derived mainly from vehicle emissions) become trapped in the...

A machine learning approach to integrating genetic and ecological data in tsetse flies (Glossina pallidipes) for spatially explicit vector control planning

Anusha Bishop, Giuseppe Amatulli, Chaz Hyseni, Evlyn Pless, Rosemary Bateta, Winnie Okeyo, Paul Mireji, Sylvance Okoth, Imna Malele, Grace Murilla, Serap Aksoy & Norah Saarman
Introduction - Control of vector populations is an effective strategy for addressing vector-borne disease transmission. Effective vector control requires knowledge of habitat use and connectivity. Our goal was to improve this knowledge for the tsetse species Glossina pallidipes, a vector of animal African trypanosomiasis, which is a wasting disease in livestock and represents a serious socioeconomic burden across sub-Saharan Africa. Methods and Results - We used random forest regression to: (i) Build and integrate models...

Data from: Fractal triads efficiently sample ecological diversity and processes across spatial scales

Elizabeth Simpson & William Pearse
The relative influence of ecological assembly processes, such as environmental filtering, competition, and dispersal, vary across spatial scales. Changes in phylogenetic and taxonomic diversity across environments provide insight into these processes, however, it is challenging to assess the effect of spatial scale on these metrics. Here, we outline a nested sampling design that fractally spaces sampling locations to concentrate statistical power across spatial scales in a study area. We test this design in northeast Utah,...

Data from: Population genomic evidence of selection on structural variants in a natural hybrid zone

Zachariah Gompert, Linyi Zhang, Samridhi Chaturvedi, Chris Nice & Lauren Lucas
Structural variants (SVs) can promote speciation by directly causing reproductive isolation or by suppressing recombination across large genomic regions. Whereas examples of each mechanism have been documented, systematic tests of the role of SVs in speciation are lacking. Here, we take advantage of long-read (Oxford nanopore) whole-genome sequencing and a hybrid zone between two Lycaeides butterfly taxa (L. melissa and Jackson Hole Lycaeides) to comprehensively evaluate genome-wide patterns of introgression for SVs and relate these...

American Beaver: GPS and VHF tag data from resident and translocated beavers on the Price and San Rafael Rivers, Utah

Julie Young, Emma Doden, Tal Avgar & Phaedra Budy
Wildlife translocations can dramatically alter animal movement behavior. Thus, identifying common movement patterns post-translocation can aid in setting expectations and anticipating animal behavior in subsequent efforts. American and Eurasian beavers (Castor canadensis; C. fiber) are frequently translocated for reintroduction efforts, to mitigate human-wildlife conflict, and for use as an ecosystem restoration tool. However, little is known about movement behavior of translocated beavers post-release, especially in desert rivers where resources are patchy and dynamic. We identified...

Greenhouse plant-soil feedback experiment at Cedar Creek Ecosystem Science Reserve

Ray Dybzinski, David Tilman & Noelle Beckman
We conducted a reciprocal greenhouse experiment to examine how the growth of prairie grass species depended on the soil communities conditioned by conspecific or heterospecific plant species in the field. The source soil came from monocultures in a long-term competition experiment (LTCE, Cedar Creek Ecosystem Science Reserve, MN, USA). Within the LTCE, six species of perennial prairie grasses were grown in monocultures or in eight pairwise competition plots for 12 years under conditions of low...

Data from: Cast adrift on an island: introduced populations experience an altered balance between selection and drift

Eric M. O'Neill, Karen H. Beard & Michael E. Pfrender
A long-standing question in evolutionary biology is what becomes of adaptive traits when a species expands its range into novel environments. Here we report the results of a study on an adaptive colour pattern polymorphism (stripes) of the coqui frog following its introduction to Hawaii from Puerto Rico. We compared population differentiation (φ'ST and FST) for the stripes locus —which underlies this colour pattern polymorphism— with neutral microsatellite loci to test for a signature of...

Data from: Genes and QTLs controlling inflorescence and stem branch architecture in Leymus (Poaceae: Triticeae) wildrye

Steven R. Larson, Elizabeth A. Kellogg & Kevin B. Jensen
Grass inflorescence and stem branches show recognizable architectural differences among species. The inflorescence branches of Triticeae cereals and grasses, including wheat, barley, and 400–500 wild species, are usually contracted into a spike formation, with the number of flowering branches (spikelets) per node conserved within species and genera. Perennial Triticeae grasses of genus Leymus are unusual in that the number of spikelets per node varies, inflorescences may have panicle branches, and vegetative stems may form subterranean...

Data from: Large niche differences emerge at the recruitment stage to stabilize grassland coexistence

Chengjin Chu & Peter B. Adler
Niche differences and average fitness differences jointly determine coexistence. However, little empirical information about the magnitude of these two mechanisms is available. Using multispecies population models fit to long-term demographic data for common, co-occurring species in five grassland and shrubland plant communities in western North America, we estimated the strength of stabilizing niche differences and average fitness differences. In all five communities, both pairwise and full community comparisons showed evidence for strong stabilizing mechanisms and...

Data from: Balancing sample accumulation and DNA degradation rates to optimize noninvasive genetic sampling of sympatric carnivores

Robert C. Lonsinger, Eric M. Gese, Steven J. Dempsey, Bryan M. Kluever, Lisette P. Waits & Timothy R. Johnson
Noninvasive genetic sampling, or noninvasive DNA sampling (NDS), can be an effective monitoring approach for elusive, wide-ranging species at low densities. However, few studies have attempted to maximize sampling efficiency. We present a model for combining sample accumulation and DNA degradation to identify the most efficient (i.e. minimal cost per successful sample) NDS temporal design for capture–recapture analyses. We use scat accumulation and faecal DNA degradation rates for two sympatric carnivores, kit fox (Vulpes macrotis)...

Data from: Population genomics of divergence among extreme and intermediate color forms in a polymorphic insect

Jeffrey D. Lozier, Jason M. Jackson, Michael E. Dillon & James P. Strange
Geographic variation in insect coloration is among the most intriguing examples of rapid phenotypic evolution and provides opportunities to study mechanisms of phenotypic change and diversification in closely related lineages. The bumble bee Bombus bifarius comprises two geographically disparate color groups characterized by red-banded and black-banded abdominal pigmentation, but with a range of spatially and phenotypically intermediate populations across western North America. Microsatellite analyses have revealed that B. bifarius in the USA are structured into...

Data from: Comparing process-based and constraint-based approaches for modeling macroecological patterns

Xiao Xiao, James P. O'Dwyer & Ethan P. White
Ecological patterns arise from the interplay of many different processes, and yet the emergence of consistent phenomena across a diverse range of ecological systems suggests that many patterns may in part be determined by statistical or numerical constraints. Differentiating the extent to which patterns in a given system are determined statistically, and where it requires explicit ecological processes, has been difficult. We tackled this challenge by directly comparing models from a constraint-based theory, the Maximum...

Data from: Unexpected ancestry of Populus seedlings from a hybrid zone implies a large role for postzygotic selection in the maintenance of species

Dorothea Lindtke, Zachariah Gompert, Christian Lexer & C. Alex Buerkle
In the context of potential interspecific gene flow, the integrity of species will be maintained by reproductive barriers that reduce genetic exchange, including traits associated with prezygotic isolation or poor performance of hybrids. Hybrid zones can be used to study the importance of different reproductive barriers, particularly when both parental species and hybrids occur in close spatial proximity. We investigated the importance of barriers to gene flow that act early versus late in the life...

Data from: Genetic and morphological evidence of a geographically widespread hybrid zone between two crocodile species, Crocodylus acutus and Crocodylus moreletii

Gualberto Pacheco-Sierra, Zachariah Gompert, Jerónimo Domínguez-Laso & Ella Vázquez-Domínguez
Hybrid zones represent natural laboratories to study gene flow, divergence and the nature of species boundaries between closely related taxa. We evaluated the level and extent of hybridization between Crocodylus moreletii and C. acutus using genetic and morphological data on 300 crocodiles from 65 localities. To our knowledge, this is the first genetic study that includes the entire historic range and sympatric zone of the two species. Contrary to expectations, Bayesian admixture proportions and maximum...

Data from: Evolution of host acceptance and its reversibility in a seed beetle

Frank J. Messina & Zachariah Gompert
1. Adapting to a low-quality plant may require modification of an insect's digestive physiology, oviposition behaviour, or other host-use traits. If colonising a marginal host entails a cost, a decay in adaptation would be expected after selection is relaxed, i.e. if populations on a novel host are reverted to their high-quality ancestral host. 2. Replicate lines of the seed beetle Callosobruchus maculatus (F.) rapidly adapted to lentil seeds; larval survival rose from approximately 1 to...

Data from: Combinations of plant water-stress and neonicotinoids can lead to secondary outbreaks of Banks grass mite (Oligonychus pratensis Banks)

Alice Ruckert, L. Niel Allen & Ricardo A. Ramirez
Spider mites, a cosmopolitan pest of agricultural and landscape plants, thrive under hot and dry conditions, which could become more frequent and extreme due to climate change. Recent work has shown that neonicotinoids, a widely used class of systemic insecticides that have come under scrutiny for non-target effects, can elevate spider mite populations. Both water-stress and neonicotinoids independently alter plant resistance against herbivores. Yet, the interaction between these two factors on spider mites is unclear,...

Data from: Serum biochemistry panels in African buffalo: Defining reference intervals and assessing variability across season, age and sex

Claire E. Couch, Morgan A. Movius, Anna E. Jolles, M. Elena D. Gorman, Johanna D. Rigas, Brianna R. Beechler & M. Elena Gorman
Serum biochemical parameters can be utilized to evaluate the physiological status of an animal, and relate it to the animal’s health. In order to accurately interpret individual animal biochemical results, species-specific reference intervals (RI) must be established. Reference intervals for biochemical parameters differ between species, and physiological differences including reproductive status, nutritional resource availability, disease status, and age affect parameters within the same species. The objectives of this study were to (1) establish RI for...

Data from: Reproductive isolation and environmental adaptation shape the phylogeography of mountain pine beetle (Dendroctonus ponderosae)

Eddy J. Dowle, Ryan R. Bracewell, Michael E. Pfrender, Karen E. Mock, Barbara J. Bentz & Gregory J. Ragland
Chromosomal rearrangement can be an important mechanism driving population differentiation and incipient speciation. In the mountain pine beetle (MPB, Dendroctonus ponderosae), deletions on the Y chromosome that are polymorphic among populations are associated with reproductive incompatibility. Here we used RAD sequencing across the entire MPB range in western North America to reveal the extent of the phylogeographic differences between Y haplotypes compared to autosomal and X-linked loci. Clustering and gene flow analyses revealed three distinct...
