Urbanization impacts apex predator gene flow but not genetic diversity across an urban-rural divide

Daryl R Trumbo, Patricia E Salerno, Kenneth Logan, Mat Alldredge, Roderick B Gagne, Christopher P Kozakiewicz, Simona Kraberger, Nick Fountain-Jones, Meggan E Craft, Scott Carver, Holly B Ernest, Kevin Crooks, Sue VandeWoude & W. Chris Funk
Apex predators are important indicators of intact natural ecosystems. They are also sensitive to urbanization because they require broad home ranges and extensive contiguous habitat to support their prey base. Pumas (Puma concolor) can persist near human developed areas, but urbanization may be detrimental to their movement ecology, population structure, and genetic diversity. To investigate potential effects of urbanization in population connectivity of pumas, we performed a landscape genomics study of 130 pumas on the...

VCF file of SNP data of 556 isolates of the wheat leaf rust fungus, Puccinia triticina from 11 world-wide regions

James Kolmer
This a file of ca. 6500 SNPs of 556 isolates of the wheat leaf rust fungus, Puccina triticina from 11 worldwide regions that were mapped to the reference genome. This data was used to examine the population structure of Puccinia triticina on a worldwide basis, and to examine the evolutionary relationship between collections from a wheat progenitor, collections from durum wheat, and collections from common wheat. Groups of isolates that were highly related were found...

Delta Basin-2 Wave Experiments (2018-2019)

Nicholas J Rodgers & Chris Paola
These experiments were conducted in St. Anthony Fall Laboratory (SAFL) Delta Basin. This is a fixed based basin (5 m wide x 5 m long x 0.5 m deep) that is fed sediment and water from an input source to create model deltas. Sea-level adjustment via relative sea-level rise is available in this facility and was used for these experiments along with a floating wave generator. This facility is able to collect data via an...

Data from: Comparative genomic analysis of the pheromone receptor Class 1 family (V1R) reveals extreme complexity in mouse lemurs (genus, Microcebus) and a chromosomal hotspot across mammals

Kelsie E Hunnicutt, George P Tiley, Rachel C Williams, Peter A Larsen, Marina B Blanco, Rodin M Rasoloarison, Christopher Ryan Campbell, Kevin Zhu, David W Weisrock, Hiroaki Matsunami & Anne D Yoder
Sensory gene families are of special interest, both for what they can tell us about molecular evolution, and for what they imply as mediators of social communication. The vomeronasal type-1 receptors (V1Rs) have often been hypothesized as playing a fundamental role in driving or maintaining species boundaries given their likely function as mediators of intraspecific mate choice, particularly in nocturnal mammals. Here, we employ a comparative genomic approach for revealing patterns of V1R evolution within...

Data from: The Fungal Endophyte Epichloë festucae var. lolii Plays a Limited Role in Mediating Crown Rust Severity in Perennial Ryegrass

Garett Heineck
Perennial ryegrass (Lolium perenne L.) is an important turf and forage species that often becomes infected with Puccinia coronata f. sp. lolii, the causal pathogen of crown rust. Disease control through clavicipitaceous endophytes has been proposed as a potential biocontrol. Two field experiments were designed to determine the influence of native Epichloë endophyte infection on natural rust development across a diverse panel of perennial ryegrass germplasm. Experiment 1 used an isogenic population design in which...

Data from: Imputation of canine genotype array data using 365 whole-genome sequences improves power of genome-wide association studies

Jessica J. Hayward, Michelle E. White, Michael Boyle, Laura M Shannon, Margret L. Casal, Marta G. Castelhano, Sharon A. Center, Vicki N. Meyers-Wallen, Kenneth W. Simpson, Nathan B. Sutter, Rory J. Todhunter & Adam R. Boyko
Genomic resources for the domestic dog have improved with the widespread adoption of a 173k SNP array platform and updated reference genome. SNP arrays of this density are sufficient for detecting genetic associations within breeds but are underpowered for finding associations across multiple breeds or in mixed-breed dogs, where linkage disequilibrium rapidly decays between markers, even though such studies would hold particular promise for mapping complex diseases and traits. Here we introduce an imputation reference...

Data from: Interaction among ploidy, breeding system, and lineage diversification

Rosana Zenil-Ferguson, J. Gordon Burleigh, William A. Freyman, Boris Igic, Itay Mayrose & Emma E. Goldberg
If particular traits consistently affect rates of speciation and extinction, broad macroevolutionary patterns can be interpreted as consequences of selection at high levels of the biological hierarchy. Identifying traits associated with diversification rates is difficult because of the wide variety of characters under consideration and the statistical challenges of testing for associations from comparative phylogenetic data. Ploidy (diploid vs. polyploid states) and breeding system (self-incompatible vs. self-compatible states) are both thought to be drivers of...

Data from: The evolutionary response of mating system to heterosis

Alexander Harkness, Yaniv Brandvain & Emma E. Goldberg
Isolation allows populations to diverge and to fix different alleles. Deleterious alleles that reach locally high frequencies contribute to genetic load, especially in inbred or selfing populations, in which selection is relaxed. In the event of secondary contact, the recessive portion of the genetic load is masked in the hybrid offspring, producing heterosis. This advantage, only attainable through outcrossing, should favor evolution of greater outcrossing even if inbreeding depression has been purged from the contributing...

Data from: Size-selective harvesting fosters adaptations in mating behavior and reproductive allocation, affecting sexual selection in fish

Valerio Sbragaglia, Catalina Gliese, David Bierbach, Andrew Honsey, Silva Uusi-Heikkilä & Robert Arlinghaus
1. The role of sexual selection in the context of harvest-induced evolution is poorly understood. However, elevated and trait-selective harvesting of wild populations may change sexually-selected traits, which in turn can affect mate choice and reproduction. 2. We experimentally evaluated the potential for fisheries-induced evolution of mating behavior and reproductive allocation in fish. 3. We used a unique experimental system of zebrafish (Danio rerio) lines exposed to large, small, or random (i.e. control) size-selective mortality....

Data from: Patterns of nitrogen-fixing tree abundance in forests across Asia and America

Duncan N. L. Menge, Ryan A. Chisholm, Stuart J. Davies, Kamariah Abu Salim, David Allen, Mauricio Alvarez, Norm Bourg, Warren Y. Brockelman, Sarayudh Bunyavejchewin, Nathalie Butt, Min Cao, Wirong Chanthorn, Wei-Chun Chao, Keith Clay, Richard Condit, Susan Cordell, João Batista Da Silva, H. S. Dattaraja, Ana Cristina Segalin De Andrade, Alexandre A. Oliveira, Jan Den Ouden, Michael Drescher, Christine Fletcher, Christian P. Giardina, C. V. Savitri Gunatilleke … & Tak Fung
Symbiotic nitrogen (N)‐fixing trees can provide large quantities of new N to ecosystems, but only if they are sufficiently abundant. The overall abundance and latitudinal abundance distributions of N‐fixing trees are well characterised in the Americas, but less well outside the Americas. Here, we characterised the abundance of N‐fixing trees in a network of forest plots spanning five continents, ~5,000 tree species and ~4 million trees. The majority of the plots (86%) were in America...

Data from: City sicker? a meta-analysis of wildlife health and urbanization

Maureen H. Murray, Cecilia A. Sanchez, Daniel J. Becker, Kaylee A. Byers, Katherine E. L. Worsley-Tonks & Meggan E. Craft
Urban development can alter resource availability, land use, and community composition, in turn influencing wildlife health. Generalizable relationships between wildlife health and urbanization have yet to be quantified, and could vary across health metrics and animal taxonomy. We present a phylogenetic meta-analysis of 516 records spanning 81 wildlife species from 106 studies comparing the toxicant loads, parasitism, body condition, or stress of urban and non-urban wildlife populations in 30 countries. We find a significantly negative...

SAM Filtering Pipeline (SFP): Algorithm for the determination of integration sites from next generation sequencing data

Sofie A O'Brien & Wei-Shou Hu
The locus at which a vector harboring a product transgene integrates into the genome can have a profound effect on the transgene’s transcript level and the stability of the resulting cell line. In order to identify integration site(s) of a transfected vector from next generation genome sequencing data, the SAM filtering pipeline (SFP) was created. It is best suited for targeted sequence data, such as that from sequence capture of probed vector regions. However, it...

Data from: Feline immunodeficiency virus in puma: estimation of force of infection reveals insights into transmission

Jennifer Reynolds, Scott Carver, Mark Cunningham, Ken Logan, Winston Vickers, Kevin Crooks, Sue VandeWoude & Meggan Craft
Determining parameters that govern pathogen transmission (such as the force of infection, FOI), and pathogen impacts on morbidity and mortality, is exceptionally challenging for wildlife. Vital parameters can vary, for example across host populations, between sexes and within an individual's lifetime. Feline immunodeficiency virus (FIV) is a lentivirus affecting domestic and wild cat species, forming species-specific viral--host associations. FIV infection is common in populations of puma (Puma concolor), yet uncertainty remains over transmission parameters and...

Data from: Nitrogen addition reduced ecosystem stability regardless of its impacts on plant diversity

Jushan Liu, Xiaofei Li, Quanhui Ma, Xiang Zhang, Ying Chen, Forest Isbell & Deli Wang
1. Global environmental changes are altering ecosystem stability, sometimes by altering biodiversity. For example, by driving grassland plant species loss, nitrogen (N) addition can reduce ecosystem stability. In other cases, however, N addition may alter productivity and ecosystem stability, by increasing the dominance of particularly productive or stable species. 2. We examined how N addition affected plant diversity, productivity, and the temporal stability of productivity in an 8-year grassland experiment. We found that N addition...

Data from: Natural and sexual selection on cuticular hydrocarbons: a quantitative genetic analysis

Jacob D. Berson, Marlene Zuk & Leigh W. Simmons
While the reproductive benefits of sexual displays have been widely studied, we have relatively limited evidence of the fitness costs associated with most display traits. Insect cuticular hydrocarbon (CHC) profiles are sexually selected traits that also protect against desiccation. These two functions are thought to oppose each other, with investment in particular compounds believed to increase attractiveness at the expense of compounds that protect against water-loss. We investigated this potential trade-off in a quantitative genetic...

Data from: Resistance of soil biota and plant growth to disturbance increases with plant diversity

Jonathan Bennett, Alexander Koch, Jennifer Forsythe, Nancy Johnson, David Tilman & John Klironomos
Plant diversity is critical to the functioning of ecosystems, potentially mediated in part by interactions with soil biota. Here, we characterized multiple groups of soil biota across a plant diversity gradient in a long-term experiment. We then subjected soil samples taken along this gradient to drought, freezing, and a mechanical disturbance to test how plant diversity affects the responses of soil biota and growth of a focal plant to these disturbances. High plant diversity resulted...

Data from: Geographic variation in thermal sensitivity of early life traits in a widespread reptile

Brooke L. Bodensteiner, Daniel A. Warner, John B. Iverson, Carrie L. Milne-Zelman, Timothy S. Mitchell, Jeanine M. Refsnider & Fredric J. Janzen
Taxa with large geographic distributions generally encompass diverse macroclimatic conditions, potentially requiring local adaptation and/or phenotypic plasticity to match their phenotypes to differing environments. These eco-evolutionary processes are of particular interest in organisms with traits that are directly affected by temperature, such as embryonic development in oviparous ectotherms. Here we examine the spatial distribution of fitness-related early-life phenotypes across the range of a widespread vertebrate, the painted turtle (Chrysemys picta). We quantified embryonic and hatchling...

Data from: Meta-analytic and economic approaches for evaluation of pesticide impact on Sclerotinia stem rot control and soybean yield in the North Central U.S.

Jaime F. Willbur, Paul Mitchell, Mamadou L. Fall, Adam M. Byrne, Scott Chapman, Crystal M. Floyd, Carl A. Bradley, Keith Ames, Martin I. Chilvers, Nathan Kleczewski, Dean Malvick, Brian Mueller, Daren Mueller, Mehdi Kabbage, Shawn P. Conley & Damon Smith
As complete host resistance in soybean has not been achieved, Sclerotinia stem rot (SSR) caused by Sclerotinia sclerotiorum continues to be of major economic concern for farmers. Thus, chemical control remains a prevalent disease management strategy. Pesticide evaluations were conducted in Illinois, Iowa, Michigan, Minnesota, New Jersey, and Wisconsin from 2009 to 2016, for a total of 25 site-years (n = 2057 plot-level data points). These studies were used in network meta-analyses to evaluate the...

Data from: Adult nutritional stress decreases oviposition choosiness and fecundity in female butterflies

Sarah Jaumann & Emilie C. Snell-Rood
Despite the benefits of careful decision-making, not all animals are choosy. One explanation is that choosiness can cost time and energy and thus depend on nutrition. However, it is not clear how allocation to choosiness versus other components of life history shifts in the face of nutritional stress. We tested two hypotheses about the effects of nutritional stress on choosiness and other life history traits: 1) poor nutrition leads to compensatory shifts in life history...

Data from: Meiotic drive shapes rates of karyotype evolution in mammals

Heath Blackmon, Joshua Justison, Itay Mayrose & Emma E. Goldberg
Chromosome number is perhaps the most basic characteristic of a genome, yet generalizations that can explain the evolution of this trait across large clades have remained elusive. Using karyotype data from over 1,000 mammals, we developed and applied a phylogenetic model of chromosome evolution that links chromosome number changes with karyotype morphology. Using our model, we infer that rates of chromosome number evolution are significantly lower in species with karyotypes that consist of either all...

Data from: Soil organic carbon stability in forests: distinct effects of tree species identity and traits

Gerrit Angst, Kevin E. Mueller, David M. Eissenstat, Susan Trumbore, Katherine H. Freeman, Sarah E. Hobbie, Jon Chorover, Jacek Oleksyn, Peter B. Reich & Carsten W. Mueller
Rising atmospheric CO2 concentrations have increased interest in the potential for forest ecosystems and soils to act as carbon (C) sinks. While soil organic C contents often vary with tree species identity, little is known about if, and how, tree species influence the stability of C in soil. Using a 40‐year‐old common garden experiment with replicated plots of eleven temperate tree species, we investigated relationships between soil organic matter (SOM) stability in mineral soils and...

Invasive species and biotic homogenization in temperate aquatic plant communities

Ranjan Muthukrishnan & Daniel Larkin
Aim: Biotic homogenization (BH), a reduction in the distinctness of species composition between geographically separated ecological communities in a region, is an important but underappreciated potential consequence of biological invasions. While BH theory has always considered invasions, it has generally been in a relatively narrow context, i.e., that the cosmopolitan nature of invasive species increases BH because of their shared presence across many locations. We sought to evaluate this component of BH as well as...

Data from: Diversifying livestock promotes multidiversity and multifunctionality in managed grasslands

Ling Wang, Manuel Delgado-Baquerizo, Deli Wang, Forest Isbell, Jun Liu, Chao Feng, Jushan Liu, Zhiwei Zhong, Hui Zhu, Xia Yuan, Qing Chang & Chen Liu
Increasing plant diversity can increase ecosystem functioning,stability, and services in both natural and managed grasslands,but the effects of herbivore diversity, and especially of livestock diversity, remain underexplored. Given that managed grazing is the most extensive land use worldwide, and that land managers can readily change livestock diversity, we experimentally tested how livestock diversification (sheep, cattle, or both) influenced multidiversity (the diversity of plants, insects, soil microbes, and nematodes) and ecosystem multifunctionality (including plant biomass production,...

Data from: Sensitivity of global soil carbon stocks to combined nutrient enrichment

Thomas W. Crowther, Charlotte Riggs, Eric M. Lind, Elizabeth T. Borer, Eric W. Seabloom, Sarah E. Hobbie, E. R. Jasper Wubs, Peter B. Adler, Jennifer Firn, Laureano Gherardi, Nicole Hagenah, Kirsten S. Hofmockel, Johannes M. H. Knops, Rebecca L. McCulley, Andrew MacDougall, Pablo L. Peri, Suzanne M. Prober, Carly J. Stevens & Devin Routh
Soil stores approximately twice as much carbon as the atmosphere and fluctuations in the size of the soil carbon pool directly influence climate conditions. We used the Nutrient Network global change experiment to examine how anthropogenic nutrient enrichment might influence grassland soil carbon storage at a global scale. In isolation, enrichment of nitrogen and phosphorous had minimal impacts on soil carbon storage. However, when these nutrients were added in combination with potassium and micronutrients, soil...

Data from: Impact of prey occupancy and other ecological and anthropogenic factors on tiger distribution in Thailand’s Western Forest Complex

Somphot Duangchatrasiri, Pornkamol Jornburom, Sitthichai Jinamoy, Anak Pattanvibool, James E. Hines, Todd W. Arnold, John Fieberg & James L. D. Smith
1. Despite conservation efforts, large mammals such as tigers and their main prey, gaur, banteng, and sambar, are highly threatened and declining across their entire range. The only large viable source population of tigers in mainland Southeast Asia occurs in Thailand’s Western Forest Complex (WEFCOM), an approximately 19,000 km2 landscape of 17 contiguous protected areas. 2. We used an occupancy modeling framework, which accounts for imperfect detection, to identify the factors that affect tiger distribution...
