Couple-level Panel Data from the US Current Population Survey, 1976-2020

Kelly A. Musick
This study examines trends in couples’ work and earnings in the years following childbirth and the implications of these couple-level processes for changes in aggregate inequality over time. We address critical gaps in the literature regarding how couples sort into marriage and how they negotiate roles within marriage. We use four decades of successive, short-run panels from the Current Population Survey (CPS) to assess changes in husbands’ and wives’ work and earnings following a first...

Predator pheromone elicits a temporally dependent non-consumptive effect in prey

Nicholas Aflitto
The influence of predator cues on the behaviour of prey is well supported in the literature; however, a clear understanding of how predator cues affect prey in variable environmental conditions and over longer time scales is needed to better understand the underlying mechanisms. Here, we measure how predator odors affect herbivore colonization, abundance, oviposition, and plant damage across two growing seasons. The study system consisted of Leptinotarsa decemlineata (Colorado potato beetle) as prey, and the...

Data from: Genomic regions underlying metabolic and neuronal signaling pathways are temporally consistent outliers in a moving avian hybrid zone

Dominique Wagner, Robert Curry, Nancy Chen, Irby Lovette & Scott Taylor
The study of hybrid zones can provide insight into the genetic basis of species differences that are relevant for the maintenance of reproductive isolation. Hybrid zones can also provide insight into climate change, species distributions, and evolution. The hybrid zone between black-capped chickadees (Poecile atricapillus) and Carolina chickadees (P. carolinensis) is shifting northward in response to increasing winter temperatures but is not increasing in width. This pattern indicates strong selection against chickadees with admixed genomes....

Spine and dine: A key defensive trait promotes ecological success in spiny ants

Benjamin Blanchard, Akihiro Nakamura, Min Cao, Stephanie Chen & Corrie Moreau
A key focus of ecologists is explaining the origin and maintenance of morphological diversity and its association with ecological success. We investigate potential benefits and costs of a common and varied morphological trait, cuticular spines, for foraging behavior, interspecific competition, and predator-prey interactions in naturally co-occurring spiny ants (Hymenoptera: Formicidae: Polyrhachis) in an experimental setting. We expect that a defensive trait like spines might be associated with more conspicuous foraging, a greater number of workers...

Ecological factors mediate immunity and parasitic co-infection in sea fan octocorals

Allison M. Tracy, Ernesto Weil & Colleen A. Burge
The interplay among environment, demography, and host-parasite interactions is a challenging frontier. In the ocean, fundamental changes are occurring due to anthropogenic pressures, including increased disease outbreaks on coral reefs. These outbreaks often include multiple parasites, calling into question how coral immunity functions in this complex milieu. Corals provide an interesting model to study ecological immunity during co-infection, being highly sensitive to environmental change, susceptible to many diseases, and defended by the innate immune system....

Data from: Dominant bee species and floral abundance drive parasite temporal dynamics in plant-pollinator communities

Peter Graystock, Wee Hao Ng, Kyle Parks, Amber D. Tripodi, Paige A. Muñiz, Ashley A. Fersch, Christopher R. Myers, Quinn S. McFrederick & Scott H. McArt
Pollinator declines can leave communities less diverse and potentially at increased risk to infectious diseases. Species-rich plant and bee communities have high species turnover, making the study of disease dynamics challenging. To address how temporal dynamics shape parasite prevalence in plant and bee communities, we screened >5,000 bees and flowers through an entire growing season for five common bee microparasites (Nosema ceranae, N. bombi, Crithidia bombi, C. expoeki and neogregarines). Over 110 bee species and...

Honey bees and wild pollinators differ in their preference for and use of introduced floral resources

Christine Urbanowicz, Paige Muñiz & Scott McArt
Introduced plants may be important foraging resources for honey bees and wild pollinators, but how often and why pollinators visit introduced plants across an entire plant community is not well understood. Understanding the importance of introduced plants for pollinators could help guide management of these plants and conservation of pollinator habitat. We assessed how floral abundance and pollinator preference influence pollinator visitation rate and diversity on 30 introduced vs. 24 native plants in central New...

Tracking the Near East origins and European dispersal of the house mouse

Thomas CUCCHI, Katerina Papayianni, Sophie Cersoy, Laetitia Aznar-Cormano, Antoine Zazzo, Régis Debruyne, Rémi Berthon, Adrian Bălășescu, Alan Simmons, François Valla, Yannis Hamilakis, Fanis Mavridis, Marjan Mashkour, Jamshid Darvish, Roohollah Siahsarvi, Fereidoun Biglari, Cameron A. Petrie, Lloyd Weeks, Alireza Sardari, Sepideh Maziar, Christiane Denys, David Orton, Emma Jenkins, Melinda Zeder, Jeremy B. Searle … & Jean-Denis Vigne
The house mouse (Mus musculus) is one of the most invasive mammals and an evolutionary model. However, the timing and components of its origin and dispersal remain poorly documented. To track its synanthropisation and subsequent biological invasion during the develoment of complex human societies, we analyzed 829 Mus specimens from 43 archaeological contexts in Southwestern Asia and Southeastern Europe, dating between 40,000 and 3,000 cal. BP, combining geometric morphometris numerical taxonomy with ancient mitochondrial DNA...

Lymph node metastases develop through a wider evolutionary bottleneck than distant metastases

Johannes Reiter, Wei-Ting Hung, I-Hsiu Lee, Shriya Nagpal, Peter Giunta, Sebastian Degner, Gang Liu, Emma Wassenaar, William Jeck, Martin Taylor, Alexander Farahani, Hetal Marble, Simon Knott, Onno Kranenburg, Jochen Lennerz & Kamila Naxerova
Genetic diversity among metastases is poorly understood but contains important information about disease evolution at secondary sites. Here we investigate inter- and intra-lesion heterogeneity for two types of metastases that associate with different clinical outcomes: lymph node and distant organ metastases in human colorectal cancer. We develop a rigorous mathematical framework for quantifying metastatic phylogenetic diversity. Distant metastases are typically monophyletic and genetically similar to each other. Lymph node metastases, in contrast, display high levels...

Spatial proximity moderates genotype uncertainty in genetic tagging studies

Ben Augustine, J. Andrew Royle, Daniel W. Linden & Angela K. Fuller
Accelerating declines of an increasing number of animal populations worldwide necessitate methods to reliably and efficiently estimate demographic parameters such as population density and trajectory. Standard methods for estimating demographic parameters from noninvasive genetic samples are inefficient because lower quality samples cannot be used, and they do not allow for errors in individual identification. We introduce the Genotype Spatial Partial Identity Model (SPIM), which integrates a genetic classification model with a spatial population model to...

Tracking invasions of a destructive defoliator, the gypsy moth (Erebidae: Lymantria dispar): population structure, origin of intercepted specimens, and Asian introgression into North America

Yunke Wu, Steven Bogdanowicz, Jose Andres, Kendra Vieira, Baode Wang, Allard Cossé & Scott Pfister
Genetic data can help elucidate the dynamics of biological invasions, which are fueled by the constant expansion of international trade. The introduction of European gypsy moth (Lymantria dispar dispar) into North America is a classic example of human-aided invasion that has caused tremendous damage to North American temperate forests. Recently, the even more destructive Asian gypsy moth (mainly L. d. asiatica and L. d. japonica) has been intercepted in North America, mostly transported by cargo...

Brevity is not a universal in animal communication: evidence for compression depends on the unit of analysis in small ape vocalizations

Dena Clink, Abdul Hamid Ahmad & Holger Klinck
Evidence for compression, or minimization of code length, has been found across biological systems from genomes to human language and music. Two linguistic laws—Menzerath’s law (which states that longer sequences consist of shorter constituents) and Zipf’s law of abbreviation (a negative relationship between signal length and frequency of use) are predictions of compression. It has been proposed that compression is a universal in animal communication, but there have been mixed results, particularly in reference to...

Data from: Data from: Seasonal polyphenism of Spotted-wing Drosophila is affected by variation in local abiotic conditions within its invaded range, likely influencing survival and regional population dynamics

Dara Stockton, Anna Wallingford, Gabrielle Brind'amore, Lindsy Iglesias, Lauren Diepenbrock, Hannah Burrack, Heather Leach, Elissa Ballman, Janet Van Zoeren, Rufus Isaacs, Oscar Liburd, Francis Drummond, Christelle Guédot & Greg Loeb
1. Overwintering Drosophila often display adaptive phenotypic differences beneficial for survival at low temperatures. However, it is unclear which morphological traits are the best estimators of abiotic conditions, how those traits are correlated with functional outcomes in cold tolerance, and whether there are regional differences in trait expression. 2. We used a combination of controlled laboratory assays, and collaborative field collections of invasive Drosophila suzukii in different areas of the United States, to study the...

Data from: Genomic and plumage variation across the historically controversial Baltimore and Bullock’s oriole hybrid zone

Jennifer Walsh, Shawn Billerman, Vanya Rohwer, Bronwyn Butcher & Irby Lovette
Hybrid zones are powerful natural settings for investigating how birds diversify into distinct species. Here we present the first genomic-scale exploration of the Baltimore (Icterus galbula) and Bullock’s (I. bullockii) oriole hybrid zone, which is notable for its long history of study and for its prominence in debates about avian species concepts and species limits. We used a reduced-representation sequencing approach to generate a panel of 3,067 genetic markers for 297 orioles sampled along the...

Data from: Unraveling hierarchical genetic structure in a marine metapopulation: a comparison of three high-throughput genotyping approaches

Cassidy C. D'Aloia, Jose A. Andres, Steven M. Bogdanowicz, Amy R. McCune, Richard G. Harrison & Peter M. Buston
Marine metapopulations often exhibit subtle population structure that can be difficult to detect. Given recent advances in high-throughput sequencing, an emerging question is whether various genetic approaches, in concert with improved sampling designs, will substantially improve our understanding of genetic structure in the sea. To address this question, we explored hierarchical patterns of structure in the coral reef fish Elacatinus lori using a high-resolution approach with respect to both genetic and geographic sampling. Previously, we...

Human mediated land use change drives intraspecific plant trait variation

Hayley Schroeder, Heather Grab, Andre Kessler & Katja Poveda
In the Anthropocene, more than three quarters of ice-free land has experienced some form of human driven habitat modification, with agriculture dominating 40% of the Earth’s surface. This land use change alters the quality, availability, and configuration of habitat resources, affecting the community composition of plants and insects, as well as their interactions with each other. Landscapes dominated by agriculture are known to support a lower abundance and diversity of pollinators and frequently larger populations...

Data from: Variance in within-pair reproductive success influences the opportunity for selection annually and over the lifetimes of males in a multi-brooded songbird

Ryan Germain, Michael Hallworth, Sara Kaiser, Scott Sillett & Michael Webster
In socially monogamous species, male reproductive success consists of ‘within-pair’ offspring produced with their socially-paired mate(s), and ‘extra-pair’ offspring produced with additional females throughout the population. Both reproductive pathways offer distinct opportunities for selection in wild populations, as each is composed of separate components of mate attraction, female fecundity, and paternity allocation. Identifying key sources of variance and covariance among these components is a crucial step towards understanding the reproductive strategies that males use to...

Evidence supporting the microbiota-gut-brain axis in a songbird

Morgan Slevin, Jennifer Houtz, & Rindy Anderson
Recent research in mammals supports a link between cognitive ability and the gut microbiome, but little is known about this relationship in other taxa. In a captive population of 38 Zebra Finches (Taeniopygia guttata), we quantified performance on cognitive tasks measuring learning and memory. We sampled the gut microbiome via cloacal swab and quantified bacterial alpha and beta diversity. Performance on cognitive tasks related to beta diversity but not alpha diversity. We then identified differentially...

Data from Cretaceous-Paleogene plant extinction and recovery in Patagonia

Elena Stiles, Peter Wilf, Ari Iglesias, María Alejandra Gandolfo & N. Rubén Cúneo
The Cretaceous-Paleogene (K/Pg) extinction appears to have been geographically heterogeneous for some organismal groups. Southern Hemisphere K/Pg palynological records have shown lower extinction and faster recovery than in the Northern Hemisphere, but no comparable, well-constrained Southern Hemisphere macrofloras spanning this interval had been available. Here, macrofloral turnover patterns are addressed for the first time in the Southern Hemisphere, using over 3,500 dicot leaves from the latest Cretaceous (Maastrichtian) and the earliest Paleocene (Danian) of Argentine...

Pollen transfer networks reveal alien species as main heterospecific pollen donors with fitness consequences for natives

Victor Parra-Tabla, Conchita Alonso, Tia-Lynn Ashman, Robert Raguso, Cristopher Albor, Paula Sosenski, Diego Carmona & Gerardo Arceo-Gómez
The ecological dynamics of co-flowering communities are largely mediated by pollinators. However, current understanding of pollinator-mediated interactions primarily relies on how co-flowering plants influence attraction of shared pollinators, and much less is known about plan-plant interactions that occur via heterospecific pollen (HP) transfer. Invaded communities in particular can be highly affected by the transfer of alien pollen, but the strength, drivers, and fitness consequences of these interactions at a community scale are not well understood....

Data and analyses from: Herbivory and time since flowering shape floral rewards and pollinator-pathogen interactions

Luis A. Aguirre, Julie K. Davis, Philip C. Stevenson & Lynn S. Adler
Herbivory can induce chemical changes throughout plant tissues including flowers, which could affect pollinator-pathogen interactions. Pollen is highly defended compared to nectar, but no study has examined whether herbivory affects pollen chemistry. We assessed the effects of leaf herbivory on nectar and pollen alkaloids in Nicotiana tabacum, and how herbivory-induced changes in nectar and pollen affect pollinator-pathogen interactions. We damaged leaves of Nicotiana tabacum using the specialist herbivore Manduca sexta and compared nicotine and anabasine...

Data for: Genetic architecture modulates diet induced hepatic mRNA and miRNA expression profiles

Excel Que, Kristen L. James, Alisha R. Coffey, Tangi L. Smallwood, Jody Albright, M. Nazmul Huda, Daniel Pomp, Praveen Sethupathy & Brian J. Bennett
Genetic approaches in model organisms have consistently demonstrated that molecular traits such as gene expression are under genetic regulation, similar to clinical traits. The resulting expression quantitative trait loci (eQTL) have revolutionized our understanding of genetic regulation and identified numerous candidate genes for clinically-relevant traits. More recently, these analyses have been extended to other molecular traits such as protein abundance, metabolite levels, and miRNA expression. Here we performed global hepatic eQTL and miRNA expression quantitative...

Footprints of local adaptation span hundreds of linked genes in the Atlantic silverside genome

Aryn Wilder, Stephen Palumbi, David Conover & Nina Overgaard Therkildsen
The study of local adaptation in the presence of ongoing gene flow is the study of natural selection in action, revealing the functional genetic diversity most relevant to contemporary pressures. In addition to individual genes, genome-wide architecture can itself evolve to enable adaptation. Distributed across a steep thermal gradient along the east coast of North America, Atlantic silversides (Menidia menidia) exhibit an extraordinary degree of local adaptation in a suite of traits, and the capacity...

Extensive hybridization reveals multiple coloration genes underlying a complex plumage phenotype

Stepfanie Aguillon, Jennifer Walsh & Irby Lovette
Coloration is an important target of both natural and sexual selection. Discovering the genetic basis of colour differences can help us to understand how this visually striking phenotype evolves. Hybridizing taxa with both clear colour differences and shallow genomic divergences are unusually tractable for associating coloration phenotypes with their causal genotypes. Here, we leverage the extensive admixture between two common North American woodpeckers—yellow-shafted and red-shafted flickers—to identify the genomic bases of six distinct plumage patches...
