Data from: Range-wide distribution of genetic diversity in the North American tree Juglans cinerea: a product of range shifts, not ecological marginality or recent population decline

Sean M Hoban, Daniel S Borkowski, Sunshine L Brosi, Tim S McCleary, Laura M Thompson, Jason S McLachlan, Marie A Pereira, Scott E Schlarbaum & Jeanne Romero-Severson
The spatial distribution of genetic diversity is a product of recent and historical ecological processes, as well as anthropogenic activities. A current challenge in population and conservation genetics is to disentangle the relative effects of these processes, as a first step in predicting population response to future environmental change. In this investigation we compare the influence of contemporary population decline, contemporary ecological marginality, and postglacial range shifts. Using classical model comparison procedures and Bayesian methods,...

Data from: Behavioral evidence for fruit odor discrimination and sympatric host races of Rhagoletis pomonella flies in the western United States

Charles E. Linn, Wee L. Yee, Sheina B. Sim, Dong H. Cha, Thomas Powell, Robert B. Goughnour & Jeffrey L. Feder
The recent shift of Rhagoletis pomonella (Diptera: Tephritidae) from its native host downy hawthorn, Crataegus mollis, to introduced domesticated apple, Malus domestica, in the eastern U.S. is a model for sympatric host race formation. However, the fly is also present in the western U.S., where it may have been introduced via infested apples within the last 60 years. In addition to apple, R. pomonella also infests two hawthorns in the West, one the native black...

Data from: Genetic divergence along the speciation continuum: the transition from host race to species in Rhagoletis (Diptera: Tephritdae)

Thomas H. Q. Powell, Glen R. Hood, Mason O. Murphy, Jeffrey S. Heilveil, Stewart H. Berlocher, Partrik Nosil, Jeffrey L. Feder & Patrik Nosil
Studies of related populations varying in their degrees of reproductive isolation can provide insights into speciation. Here, the transition from partially isolated host races to more fully separated sibling species is investigated by comparing patterns of genetic differentiation between recently evolved (∼150 generations) apple and ancestral hawthorn-infesting populations of Rhagoletis pomonella to their sister taxon, the undescribed flowering dogwood fly attacking Cornus florida. No fixed or diagnostic private alleles differentiating the three populations were found...

Data from: Mate choice strategies in a spatially-explicit model environment

Giordano B.S. Ferreira, Matthias Scheutz, Sunny K. Boyd & Giordano B. S. Ferreira
Decisions about the choice of a mate can greatly impact both individual fitness and selection processes. We developed a novel agent-based model to investigate two common mate choice rules that may be used by female gray treefrogs (Hyla versicolor). In this model environment, female agents using the minimum-threshold strategy found higher quality mates and traveled shorter distances on average, compared with female agents using the best-of-n strategy. Females using the minimum-threshold strategy, however, incur significant...

Elucidating mechanisms of invasion success: effects of parasite removal on growth and survival rates of invasive and native frogs

Elizabeth Roznik, Kerri Surbaugh, Natalia Cano & Jason Rohr
1. Identifying the mechanisms underlying biological invasions can inform the management of invasive species. The enemy release hypothesis (ERH) suggests that invasive species have a competitive advantage in their introduced range because they leave behind many of their predators and parasites from their native range, allowing them to shift resources from defenses to growth, reproduction, and dispersal. Many studies have demonstrated that invasive species have fewer parasites than their native counterparts, but few studies have...

Data from: Quantification of mesocosm fish and amphibian species diversity via eDNA metabarcoding

Nathan T. Evans, Brett P. Olds, Cameron R. Turner, Mark A. Renshaw, Yiyuan Li, Christopher L. Jerde, Andrew R. Mahon, Michael E. Pfrender, Gary A. Lamberti & David M. Lodge
Freshwater fauna are particularly sensitive to environmental change and disturbance. Management agencies frequently use fish and amphibian biodiversity as indicators of ecosystem health and a way to prioritize and assess management strategies. Traditional aquatic bioassessment that relies on capture of organisms via nets, traps and electrofishing gear typically has low detection probabilities for rare species and can injure individuals of protected species. Our objective was to determine whether environmental DNA (eDNA) sampling and metabarcoding analysis...

Data from: Interbirth intervals in wild baboons: environmental predictors and hormonal correlates

Laurence R. Gesquiere, Jeanne Altmann, Elizabeth A. Archie & Susan C. Alberts
Objectives: Interbirth intervals (IBIs) are a key metric of female reproductive success; understanding how they are regulated by environmental, social, and demographic factors can provide insight into sources of variance in female fitness. Materials and Methods: Using 36 years of reproductive data on 490 IBIs for 160 wild female baboons, we identified sources of variance in the duration of IBIs and of their component phases: postpartum amenorrhea (PPA), sexual cycling, and pregnancy. We also examined...

Data from: Costs of reproduction in a long-lived female primate: injury risk and wound healing

Elizabeth A. Archie, Jeanne Altmann & Susan C. Alberts
Reproduction is a notoriously costly phase of life, exposing individuals to injury, infectious disease, and energetic tradeoffs. The strength of these costs should be influenced by life history strategies, and in long-lived species, females may be selected to mitigate costs of reproduction because life span is such an important component of their reproductive success. Here we report evidence for two costs of reproduction that may influence survival in wild female baboons— injury risk and delayed...

Data from: The hitchhiker's guide to Europe: the infection dynamics of an ongoing Wolbachia invasion and mitochondrial selective sweep in Rhagoletis cerasi

Hannes Schuler, Kirsten Koeppler, Sabine Daxböck-Horvath, Bilal Rasool, Susanne Krumboeck, Dietmar Schwarz, Thomas Hoffmeister, Birgit Schlick-Steiner, Florian Steiner, Arndt Telschow, Christian Stauffer, Wolfgang Arthofer, Markus Riegler, Birgit C. Schlick-Steiner, Florian M. Steiner & Thomas S. Hoffmeister
Wolbachia is a maternally inherited and ubiquitous endosymbiont of insects. It can hijack host reproduction by manipulations such as cytoplasmic incompatibility (CI) to enhance vertical transmission. Horizontal transmission of Wolbachia can also result in the colonization of new mitochondrial lineages. In this study, we present a 15-year-long survey of Wolbachia in the cherry fruit fly Rhagoletis cerasi across Europe and the spatiotemporal distribution of two prevalent strains, wCer1 and wCer2, and associated mitochondrial haplotypes in...

Data from: Experimental evidence of genome-wide impact of ecological selection during early stages of speciation-with-gene-flow

Scott P. Egan, Gregory J. Ragland, Lauren Assour, Thomas H. Q. Powell, Glen R. Hood, Scott Emrich, Patrik Nosil, Jeffrey L. Feder & Thomas H.Q. Powell
Theory predicts that speciation-with-gene-flow is more likely when the consequences of selection for population divergence transitions from mainly direct effects of selection acting on individual genes to a collective property of all selected genes in the genome. Thus, understanding the direct impacts of ecologically based selection, as well as the indirect effects due to correlations among loci, is critical to understanding speciation. Here, we measure the genome-wide impacts of host-associated selection between hawthorn and apple...

Data from: Conditional fetal and infant killing by male baboons

Matthew N. Zipple, Jackson H. Grady, Jacob B. Gordon, Lydia D. Chow, Elizabeth A. Archie, Jeanne Altmann & Susan C. Alberts
Sexually selected feticide—the death of infants in utero as a result of male behaviour—has only rarely been described or analysed, although it is presumed to be favoured by the same selective pressures that favour sexually selected infanticide. To test this hypothesis, we measured the frequency of feticide and infanticide by male baboons of the Amboseli basin in Kenya, and examined which characteristics of a male and his environment made him more likely to commit feticide...

Data from: Limited genetic evidence for host plant-related differentiation in the Western cherry fruit fly Rhagoletis indifferens (Diptera: Tephritidae)

Gilbert Saint Jean, Glen R. Hood, Scott P. Egan, Thomas H.Q. Powell, Hannes Schuler, Meredith M. Doellman, Mary M. Glover, James J. Smith, Wee L. Yee, Robert B. Goughnour, Howard M.A. Thistlewood, Sheri A. Maxwell, Nusha Keyghobadi, Juan Rull, Martin Aluja, Jeffrey L. Feder & Thomas H. Q. Powell
The shift of the fruit fly Rhagoletis pomonella (Walsh) in the mid-1800s from downy hawthorn, Crataegus mollis (Torrey & Asa Gray) Scheele, to introduced domesticated apple, Malus domestica (Borkhausen), in the eastern USA is a model for ecological divergence with gene flow. A similar system may exist in the northwestern USA and British Columbia, Canada, where Rhagoletis indifferens Curran (Diptera: Tephritidae) attacks the native bitter cherry Prunus emarginata (Douglas ex Hooker) Eaton (Rosaceae). Populations of...

Data from: Historical contingency in a multigene family facilitates adaptive evolution of toxin resistance

Joel McGlothlin, Megan Kobiela, Chris R. Feldman, Todd A. Castoe, Shana L. Geffeney, Charles T. Hanifin, Gabriela Toledo, Freek J. Vonk, Michael K. Richardson, , Michael Pfrender &
Novel adaptations must originate and function within an already established genome [ 1 ]. As a result, the ability of a species to adapt to new environmental challenges is predicted to be highly contingent on the evolutionary history of its lineage [ 2–6 ]. Despite a growing appreciation of the importance of historical contingency in the adaptive evolution of single proteins [ 7–11 ], we know surprisingly little about its role in shaping complex adaptations...

Data from: Ovarian cycling and reproductive state shape the vaginal microbiota in wild baboons

Elizabeth A. Miller, Joshua A. Livermore, Susan C. Alberts, Jenny Tung & Elizabeth A. Archie
Background: The vaginal microbiome is an important site of bacterial-mammalian symbiosis. This symbiosis is currently best characterized for humans, where lactobacilli dominate the microbial community and may help defend women against infectious disease. However, lactobacilli do not dominate the vaginal microbiota of any other mammal studied to date, raising key questions about the forces that shape the vaginal microbiome in non-human mammals. Results: We used Illumina sequencing of the bacterial 16S rRNA gene to investigate...

Key words related to public engagement with science by Society of Freshwater Science journals and conference sessions (1997-2019)

Ayesha S. Burdett, Katherine E. O’Reilly, Rebecca J. Bixby & Selena S. Connealy
Data set that was used to determine the frequency each of 4 key words (public engagement, education, outreach, or science communication) in the title or abstract of published papers in Freshwater Science (formerly the Journal of the North American Benthological Society) and oral presentations (talks) at the annual Society for Freshwater Science meetings from 1997 to 2019. Does not include any data on talks for 2013-2014 because they were not published during those years.

Indoor dust as a matrix for surveillance of COVID-19 outbreaks

Nicole Renninger, Nick Nastasi, Ashleigh Bope, Samuel Cochran, Sarah Haines, Neeraja Balasubrahmaniam, Katelyn Stuart, Aaron Bivins, Kyle Bibby, Natalie Hull & Karen Dannemiller
Ongoing disease surveillance is a critical tool to mitigate viral outbreaks, especially during a pandemic. Environmental monitoring has significant promise even following widespread vaccination among high-risk populations. The goal of this work is to demonstrate molecular SARS-CoV-2 monitoring in bulk floor dust and related samples as a proof-of-concept of a non-invasive environmental surveillance methodology for COVID-19 and potentially other viral diseases. Surface swab, passive sampler, and bulk floor dust samples were collected from rooms of...

What does it mean to be wild? Assessing human influence on the environments of nonhuman primate specimens in museum collections

Andrea Eller, Stephanie Canington, Sana Saiyed, Rita Austin, Courtney Hofman & Sabrina Sholts
Natural history collections are often thought to represent environments in a pristine natural state, free from human intervention – the so-called “wild”. In this study, we aim to assess the level of human influence represented by natural history collections of wild-collected primates over 120 years at the Smithsonian Institution’s National Museum of Natural History (NMNH). Our sample consisted of 875 catarrhine primate specimens in NMNH collections, representing 13 genera collected in 39 countries from 1882...

Data from: Rapid evolution of sex frequency and dormancy as hydroperiod adaptations

Hilary A. Smith & Terry W. Snell
Dormancy can serve as an adaptation to persist in variable habitats, and often is coupled with sex. In cyclically parthenogenetic rotifers an asexual phase enables rapid population growth, whereas sex results in diapausing embryos capable of tolerating desiccation. Few studies have experimentally tested whether sex-dormancy associations in temporary waters reflect evolution in response to the short hydroperiod selecting for diapause ability. Here we demonstrate evolution of higher propensity for sex and dormancy in ephemeral rotifer...

Data from: On the scent of standing variation for speciation: behavioral evidence for native sympatric host races of Rhagoletic pomonella (Diptera: Tephritidae) in the southern United States

Thomas H. Q. Powell, , Dong H. Cha & Jeffrey L. Feder
Standing variation can be critical for speciation. Here, we investigate the origins of fruit odor discrimination for Rhagoletis pomonella underlying the fly’s sympatric shift in the northeastern U.S. from downy hawthorn (Crataegus mollis) to apple (Malus domestica). Because R. pomonella mate on host fruit, preferences for natal fruit volatiles generate prezygotic isolation. Apples emit volatiles that appear to be missing from gas chromatography/electroantennographic detection profiles for flies infesting downy hawthorns, raising the question of how...

Data from: Theoretical models of the influence of genomic architecture on the dynamics of speciation

Samuel M. Flaxman, Aaron C. Wacholder, Jeffrey L. Feder & Patrik Nosil
A long-standing problem in evolutionary biology has been determining whether and how gradual, incremental changes at the gene level can account for rapid speciation and bursts of adaptive radiation. Using genome-scale computer simulations, we extend previous theory showing how gradual adaptive change can generate nonlinear population transitions, resulting in the rapid formation of new, reproductively isolated species. We show that these transitions occur via a mechanism rooted in a basic property of biological heredity: the...

Data from: Group living and male dispersal predict the core gut microbiome in wild baboons

Laura E. Grieneisen, Josh Livermore, Susan Alberts, Jenny Tung & Elizabeth A. Archie
The mammalian gut microbiome plays a profound role in the physiology, metabolism, and overall health of its host. However, biologists have only a nascent understanding of the forces that drive inter-individual heterogeneity in gut microbial composition, especially the role of host social environment. Here we used 178 samples from 78 wild yellow baboons (Papio cynocephalus) living in two social groups to test how host social context, including group living, social interactions within groups, and transfer...

Data from: Environmental context and contaminant biotransport by Pacific salmon interact to mediate the bioaccumulation of contaminants by stream-resident fish

Brandon S. Gerig, Dominic T. Chaloner, David J. Janetski, Ashley H. Moerke, Richard R. Rediske, James P. O'Keefe, Dilkushi A. De Alwis Pitts & Gary A. Lamberti
1.The extent to which environmental context mediates the bioaccumulation of biotransported contaminants by stream-resident organisms is poorly understood. For example, it is unclear the extent to which contaminant type, instream characteristics, or resident fish identity interact to influence the uptake of contaminants deposited by Pacific salmon (Oncorhynchus spp.) during their spawning runs. 2.To address this uncertainty, we sampled four stream-resident fish species from 13 watersheds of the Laurentian Great Lakes in locations with and without...

Data from: Spatiotemporal incidence of Zika and associated environmental drivers for the 2015-2016 epidemic in Colombia

Amir S. Siraj, I. Rodriguez-Barraquer, Christopher M. Barker, Natalia Tejedor-Garavito, Dennis Harding, Christopher Lorton, Dejan Lukacevic, Gene Oates, Guido Espana, Moritz U. G. Kraemer, Carrie Manore, Michael A. Johansson, Andrew J. Tatem, Robert C. Reiner & T. Alex Perkins
Despite a long history of mosquito-borne virus epidemics in the Americas, the impact of the Zika virus (ZIKV) epidemic of 2015-2016 was unexpected. The need for scientifically informed decision-making is driving research to understand the emergence and spread of ZIKV. To support that research, we assembled a data set of key covariates for modeling ZIKV transmission dynamics in Colombia, where ZIKV transmission was widespread and the government made incidence data publically available. On a weekly...

Data from: A century of genetic variation inferred from a persistent soil-stored seed bank

Jennifer L. Summers, Brittany Bernik, Colin J. Saunders, Jason S. McLachlan & Michael J. Blum
Stratigraphic accretion of dormant propagules in soil can result in natural archives useful for studying ecological and evolutionary responses to environmental change. Few attempts have been made, however, to use soil-stored seed banks as natural archives, in part because of concerns over non-random attrition and mixed stratification. Here we examine the persistent seed bank of Schoenoplectus americanus, a foundational brackish marsh sedge, to determine whether it can serve as a resource for reconstructing historical records...

Data from: Chromosomal inversions and ecotypic differentiation in Anopheles gambiae: the perspective from whole-genome sequencing

R. Rebecca Love, Aaron M. Steele, Mamadou B. Coulibaly, Sekou F. Traore, Scott J. Emrich, Michaël C. Fontaine & Nora J. Besansky
The molecular mechanisms and genetic architecture that facilitate adaptive radiation of lineages remain elusive. Polymorphic chromosomal inversions, due to their recombination-reducing effect, are proposed instruments of ecotypic differentiation. Here we study an ecologically diversifying lineage of An. gambiae, known as the Bamako chromosomal form based on its unique complement of three chromosomal inversions, to explore the impact of these inversions on ecotypic differentiation. We used pooled and individual genome sequencing of Bamako, typical (non-Bamako) An....
