Data from: Impact of confinement housing on study end-points in the calf model of cryptosporidiosis

Geneva Graef, Natalie J. Hurst, Lance Kidder, Tracy L. Sy, Laura B. Goodman, Whitney D. Preston, Samuel L. M. Arnold & Jennifer A. Zambriski
Background: Diarrhea is the second leading cause of death in children < 5 years globally and the parasite genus Cryptosporidium is a leading cause of that diarrhea. The global disease burden attributable to cryptosporidiosis is substantial and the only approved chemotherapeutic, nitazoxanide, has poor efficacy in HIV positive children. Chemotherapeutic development is dependent on the calf model of cryptosporidiosis, which is the best approximation of human disease. However, the model is not consistently applied across...

Data from: Genomics of end-Pleistocene population replacement in a small mammal

Petr Kotlik, Silvia Marková, Mateusz Konczal, Wieslaw Babik & Jeremy B. Searle
Current species’ distributions at high latitudes are the product of expansion from glacial refugia into previously uninhabitable areas at the end of the last glaciation. The traditional view of postglacial colonization is that southern populations expanded their ranges into unoccupied northern territories. Recent findings on mitochondrial DNA (mtDNA) of British small mammals have challenged this simple colonization scenario by demonstrating a more complex genetic turnover in Britain during the Pleistocene-Holocene transition where one mtDNA clade...

Data from: Early development of vocal interaction rules in a duetting songbird

Karla D. Rivera-Cáceres, Esmeralda Quirós-Guerrero, Marcelo Araya-Salas, Christopher N. Templeton & William A. Searcy
Exchange of vocal signals is an important aspect of animal communication. Although birdsong is the premier model for understanding vocal development, the development of vocal interaction rules in birds and possible parallels to humans have been little studied. Many tropical songbirds engage in complex engage in vocal interactions in the form of duets between mated pairs. In some species duets show precise temporal coordination and follow rules (duet codes) governing which song type one bird...

Data from: Wild acorn woodpeckers recognize associations between individuals in other groups

Michael A. Pardo, Emilee A. Sparks, Tejal S. Kuray, Natasha D. Hagemeyer, Eric L. Walters & Walter D. Koenig
According to the social intelligence hypothesis, understanding the cognitive demands of the social environment is key to understanding the evolution of intelligence. Many important socio-cognitive abilities, however, have primarily been studied in a narrow subset of the social environment—within-group social interactions—despite the fact that between-group social interactions often have a substantial effect on fitness. In particular, triadic awareness (knowledge about the relationships and associations between others) is critical for navigating many types of complex social...

Data from: Evolution of interspecies unilateral incompatibility in the relatives of Arabidopsis thaliana

Ling Li, Bo Liu, Xiaomei Deng, Hainan Zhao, Hongyan Li, Shilai Xing, Della D. Fetzer, Mengya Li, Mikhail E. Nasrallah, June B. Nasrallah & Pei Liu
The evolutionary concurrence of intraspecies self-incompatibility (SI) and explosive angiosperm radiation in the Cretaceous has led to the hypothesis that SI was one of the predominant drivers of rapid speciation in angiosperms. Interspecies unilateral incompatibility (UI) usually occurs when pollen from a self-compatible (SC) species is rejected by the pistils of a SI species, while the reciprocal pollination is compatible (UC). Although this SI x SC type UI is most prevalent and viewed as a...

Data from: Ecological sorting and character displacement contribute to the structure of communities of Clarkia species

Katherine E. Eisen & Monica Ann Geber
Despite long‐standing interest in the evolutionary ecology of plants that share pollinators, few studies have explored how these interactions may affect communities during both community assembly (ecological sorting) and through ongoing, in situ evolution (character displacement), and how the effects of these interactions may change with community context. To determine if communities display patterns consistent with ecological sorting, we assessed the frequency of co‐occurrence of four species of Clarkia in the southern Sierra foothills (Kern...

Data from: Integrative approaches to guide conservation decisions: using genomics to define conservation units and functional corridors

Soraia Barbosa, Frederico Mestre, Thomas A. White, Joana Paupério, Paulo C. Alves & Jeremy B. Searle
Climate change and increasing habitat loss greatly impact species survival, requiring range shifts, phenotypic plasticity and/or evolutionary change for long term persistence, which may not readily occur unaided in threatened species. Therefore, defining conservation actions requires a detailed assessment of evolutionary factors. Existing genetic diversity needs to be thoroughly evaluated and spatially mapped to define conservation units (CUs) in an evolutionary context, and we address that here. We also propose a multidisciplinary approach to determine...

Data from: Eco-evolutionary rescue promotes host-pathogen coexistence

Graziella V. DiRenzo, Elise F. Zipkin, Evan H. Campbell Grant, J. Andrew Royle, Ana V. Longo, Kelly R. Zamudio & Karen R. Lips
Emerging infectious pathogens are responsible for some of the most severe host mass-mortality events in wild populations. Yet, effective pathogen control strategies are notoriously difficult to identify, in part because quantifying and forecasting pathogen spread and disease dynamics is challenging. Following an outbreak, hosts must cope with the presence of the pathogen, leading to host-pathogen coexistence or extirpation. Despite decades of research, little is known about host-pathogen coexistence post-outbreak when low host abundances and cryptic...

Data from: Context-dependent interactions between pathogens and a mutualist affect pathogen fitness and mutualist benefits to hosts

Katherine M. Marchetto & Alison G. Power
Plants and animals host many microbial symbionts, including both pathogens and mutualists. However, most experimental studies include only one symbiont, and few examine interactions of more than two microbes with their host. Here, we examined whether coinfection with two pathogens causes a synergistic reduction in the benefits that hosts receive from a microbial mutualist. We also measured the effects of a microbial mutualist on the within and between host competition between coinfecting pathogens. We manipulated...

Data from: Apparent inbreeding preference despite inbreeding depression in the American crow

Andrea K. Townsend, Conor C. Taff, Melissa L. Jones, Katherine H. Getman, Sarah S. Wheeler, Mitch G. Hinton & Ryane M. Logsdon
Although matings between relatives can have negative effects on offspring fitness, apparent inbreeding preference has been reported in a growing number of systems, including those with documented inbreeding depression. Here, we examined evidence for inbreeding depression and inbreeding preference in two populations (Clinton, New York and Davis, California, USA) of the cooperatively breeding American crow (Corvus brachyrhynchos). We then compared observed inbreeding strategies with theoretical expectations for optimal, adaptive levels of inbreeding, given the inclusive...

Data from: Efficacy of negative feedback in the HPA axis predicts recovery from acute challenges.

Conor C. Taff, Cedric Zimmer & Maren N. Vitousek
The glucocorticoid stress response mediates a suite of physiological and behavioral changes that allow vertebrates to cope with transient stressors. Chronically elevated glucocorticoid levels are known to result in a variety of organismal costs, but relatively little is known about the downstream effects of mounting a series of brief, acute spikes in circulating glucocorticoids. Conceptual models of stress suggest that repeated acute stressors might produce ‘wear-and-tear’ on the stress response system when encountered in sequence....

Data from: MHC variation and blood parasites in resident and migratory populations of the common yellowthroat

Linda A. Whittingham, Peter O. Dunn, Corey R. Freeman-Gallant, Conor C. Taff & Jeff A. Johnson
Genes of the major histocompatibility complex (MHC) are a critical part of the adaptive immune response, and the most polymorphic genes in the vertebrate genome, especially in passerine birds. This diversity is thought to be influenced by exposure to pathogens which can vary in relation to numerous factors. Migratory behaviour may be a particularly important trait to consider because migratory birds are exposed to a greater number of different pathogens and parasites at both breeding...

Data from: Age and infection history are revealed by different ornaments in a warbler

Corey R. Freeman-Gallant & Conor C. Taff
Female preference for older or more disease-resistant males are both possible outcomes of parasite-mediated sexual selection, but the extent to which infection alters the development of ornaments to yield signals of male age and health has rarely been explored. In a longitudinal study of 61 male common yellowthroats (Geothlypis trichas), age-related increases in the size of the melanin-based mask and carotenoid-based bib were not correlated among young males, likely owing to differences in how blood...

Data from: Combining landscape genomics and ecological modelling to investigate local adaptation of indigenous Ugandan cattle to East Coast fever

Elia Vajana, Mario Barbato, Licia Colli, Marco Milanesi, Estelle Rochat, Enrico Fabrizi, Christopher Mukasa, Marcello Del Corvo, Charles Masembe, Vincent B. Muwanika, Fredrick Kabi, Tad Stewart Sonstegard, Heather Jay Huson, Riccardo Negrini, NextGen Consortium, Stéphane Joost & Paolo Ajmone-Marsan
East Coast fever (ECF) is a fatal sickness affecting cattle populations of eastern, central, and southern Africa. The disease is transmitted by the tick Rhipicephalus appendiculatus, and caused by the protozoan Theileria parva parva, which invades host lymphocytes and promotes their clonal expansion. Importantly, indigenous cattle show tolerance to infection in ECF-endemically stable areas. Here, the putative genetic bases underlying ECF-tolerance were investigated using molecular data and epidemiological information from 823 indigenous cattle from Uganda....

Data from: Aeroecology of a solar eclipse

Cecilia Nilsson, Kyle G. Horton, Adriaan M. Dokter, Benjamin M. Van Doren & Andrew Farnsworth
Light cues elicit strong responses from nearly all forms of life, perhaps most notably as circadian rhythms entrained by periods of daylight and darkness. Atypical periods of darkness, like solar eclipses, provide rare opportunities to study biological responses to light cues. By using a continental scale radar network, we investigated responses of flying animals to the total solar eclipse of 21 August 2017. We quantified the number of biological targets in the atmosphere at 143...

Data from: Effects of interspecific coexistence on laying date and clutch size in two closely related species of hole‐nesting birds

Anders Pape Møller, Javier Balbontin, André A. Dhondt, Vladimir Remeš, Frank Adriaensen, Clotilde Biard, Jordi Camprodon, Mariusz Cichoń, Blandine Doligez, Anna Dubiec, Marcel Eens, Tapio Eeva, Anne E. Goodenough, Andrew G. Gosler, Lars Gustafsson, Philipp Heeb, Shelley A. Hinsley, Staffan Jacob, Rimvydas Juškaitis, Toni Laaksonen, Bernard Leclercq, Bruno Massa, Tomasz D. Mazgajski, Rudi G. Nager, Jan-Åke Nilsson … & Ruedi G. Nager
Coexistence between great tits Parus major and blue tits Cyanistes caeruleus, but also other hole‐nesting taxa, constitutes a classic example of species co‐occurrence resulting in potential interference and exploitation competition for food and for breeding and roosting sites. However, the spatial and temporal variations in coexistence and its consequences for competition remain poorly understood. We used an extensive database on reproduction in nest boxes by great and blue tits based on 87 study plots across...

Data from: Variation in nest characteristics and brooding patterns of female Black-throated Blue Warblers is associated with thermal cues

Maria G. Smith, Sara A. Kaiser, T. Scott Sillett & Michael S. Webster
Thermal variation poses a problem for nesting birds and can result in reduced offspring growth rates and survival. To increase the thermal stability of the nest, females can adjust nest characteristics and nest attendance in response to changes in environmental conditions. However, it is unclear how and to what extent females modify parental behaviors during various stages of offspring development. We tested the hypothesis that females adjust nest characteristics and brooding patterns in response to...

Data from: Weak interspecific interactions in a sagebrush steppe? Conflicting evidence from observations and experiments

Peter B. Adler, Andrew Kleinhesselink, Giles Hooker, Joshua B. Taylor, Brittany Teller & Stephen P. Ellner
Stable coexistence requires intraspecific limitations to be stronger than interspecific limitations. The greater the difference between intra- and interspecific limitations, the more stable the coexistence, and the weaker the competitive release any species should experience following removal of competitors. We conducted a removal experiment to test whether a previously estimated model, showing surprisingly weak interspecific competition for four dominant species in a sagebrush steppe, accurately predicts competitive release. Our treatments were 1) removal of all...

Data from: Prey nutritional state drives divergent behavioural and physiological responses to predation risk

Natasha Tigreros, Eugenia H. Wang & Jennifer S. Thaler
1.Prey species can respond to the risk of predation with a range of antipredator behaviours and physiological changes. While these responses increase chances of survival, they often involve feeding reductions and greater energy expenditure (e.g. increases in metabolic rate). As a consequence, a prey response is constrained by its own nutritional condition. While a number of studies indeed demonstrate that prey in better nutritional condition have stronger antipredator behaviours, we do not yet understand how...

Data from: Social costs enforce honesty of a dynamic signal of motivation

Russell A. Ligon & Kevin J. McGraw
Understanding the processes that promote signal reliability may provide important insights into the evolution of diverse signaling strategies among species. The signals that animals use to communicate must comprise mechanisms that prohibit or punish dishonesty, and social costs of dishonesty have been demonstrated for several fixed morphological signals (e.g. color badges of birds and wasps). The costs maintaining the honesty of dynamic signals, which are more flexible and potentially cheatable, are unknown. Using an experimental...

Data from: Evolution of increased Medicaco polymorpha size during invasion does not result in increased competitive ability

Zoe L. Getman-Pickering, Casey P. TerHorst, Susan M. Magnoli & Jennifer A. Lau
Species invading new habitats experience novel selection pressures that can lead to rapid evolution, which may contribute to invasion success and/or increased impact on native community members. Many studies have hypothesized that plants in the introduced range will be larger than those in the native range, leading to increases in competitive ability. There is mixed support for evolution of larger sizes in the introduced range, but few studies have explicitly tested whether evolutionary changes result...

Data from: Effects of sampling effort on biodiversity patterns estimated from environmental DNA metabarcoding surveys

Erin K. Grey, Louis Bernatchez, Phillip Cassey, Kristy Deiner, Marty Deveney, Kimberley L. Howland, Anaïs Lacoursière-Roussel, Sandric Chee Yew Leong, Yiyuan Li, Brett Olds, Michael E. Pfrender, Thomas A. A. Prowse, Mark A. Renshaw & David M. Lodge
Environmental DNA (eDNA) metabarcoding can greatly enhance our understanding of global biodiversity and our ability to detect rare or cryptic species. However, sampling effort must be considered when interpreting results from these surveys. We explored how sampling effort influenced biodiversity patterns and nonindigenous species (NIS) detection in an eDNA metabarcoding survey of four commercial ports. Overall, we captured sequences from 18 metazoan phyla with minimal differences in taxonomic coverage between 18 S and COI primer...

Data from: Direct-to-consumer DNA testing of 6,000 dogs reveals 98.6-kb duplication associated with blue eyes and heterochromia in Siberian Huskies

Petra E. Deane-Coe, Erin T. Chu, Andrea Slavney, Adam R. Boyko & Aaron J. Sams
Consumer genomics enables genetic discovery on an unprecedented scale by linking very large databases of personal genomic data with phenotype information voluntarily submitted via web-based surveys. These databases are having a transformative effect on human genomics research, yielding insights on increasingly complex traits, behaviors, and disease by including many thousands of individuals in genome-wide association studies (GWAS). The promise of consumer genomic data is not limited to human research, however. Genomic tools for dogs are...

Data from: Seed ingestion and germination in rattlesnakes: overlooked agents of rescue and secondary dispersal

Randall S. Reiserer, Gordon W. Schuett & Harry W. Greene
Seed dispersal is a key evolutionary process and a central theme in the population ecology of terrestrial plants. The primary producers of most land-based ecosystems are propagated by and maintained through various mechanisms of seed dispersal that involve both abiotic and biotic modes of transportation. By far the most common biotic seed transport mechanism is zoochory, whereby seeds, or fruits containing them, are dispersed through the activities of animals. Rodents are one group of mammals...

Data from: Duetting behavior in a Neotropical ovenbird: sexual and seasonal variation and adaptive signaling functions

Pedro Diniz, , Michael S. Webster & Regina H. Macedo
Duetting is a collective behavior and might have multiple functions, including joint territory defense and mate guarding. An important step toward understanding the adaptive function of bird song is to determine if and how singing behavior varies seasonally. However, seasonal patterns for duetting species are different from the pattern described for species in which only the male sings, because song function may vary according to sex, singing role (initiator vs. responder) and level of duet...
