How open access policies affect access to grey literature in university digital repositories: A case study of iSchools

Tomas A. Lipinski & Katie Chamberlain Kritikos
An issue of interest to library and information science (LIS) scholars and practitioners is how open-access policies can affect the access and use of grey literature in university repositories. Open access (OA) refers to research placed online free from all price barriers and from most permission barriers (Suber, 2015), allowing unfettered access to scholarship and promoting open scholarly communication (Banach, 2011; Eysenbach, 2006). OA may apply research published traditionally, such as books (Schwartz, 2012) and...

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: MHC variation is related to a sexually selected ornament, survival and parasite resistance in common yellowthroats

Peter O. Dunn, Jennifer L. Bollmer, Corey R. Freeman-Gallant & Linda A. Whittingham
Hamilton and Zuk (1982) proposed that females choose mates based on ornaments whose expression is dependent on their genetically based resistance to parasites. The Major Histocompatibility Complex (MHC) plays an important role in pathogen recognition and is a good candidate for testing the relationships between immune genes and both ornament expression and parasite resistance. We tested the hypothesis that female common yellowthroats prefer to mate with more ornamented males, because it is a signal of...

MHC variation is similar in little brown bats before and after white-nose syndrome outbreak

Xueling Yi, Emily Latch, Deahn Donner, Paula Marquardt, Jonathan Palmer, Michelle Jusino, Jacqueline Frair & Daniel Lindner
White-nose syndrome (WNS), caused by the fungal pathogen Pseudogymnoascus destructans (Pd), has driven alarming declines in North American hibernating bats, such as little brown bat (Myotis lucifugus). During hibernation, infected little brown bats are able to initiate anti-Pd immune responses, indicating pathogen-mediated selection on the major histocompatibility complex (MHC) genes. However, such immune responses may not be protective as they interrupt torpor, elevate energy costs, and potentially lead to higher mortality rates. To assess whether...

The relationship between a combinatorial processing rule and a continuous mate preference function in an insect

Camille Desjonquères, Rebecca Holt, Bretta Speck & Rafael Rodriguez
Mate choice involves processing signals that can reach high levels of complexity and feature multiple components, even in small animals with tiny brains. This raises the question of whether and how such organisms deal with this complexity. One solution involves combinatorial processing, whereby different signal elements are processed as single units. Combinatorial processing has been described in several mammals and birds, and recently in a vibrationally signalling insect, Enchenopa treehoppers. Here, we ask about the...

Data from: Combinatorial signal processing in an insect

Bretta Speck, Rafael L. Rodriguez, Sara Seidita, Samuel Belo, Samuel Johnson, Caley Conley & Camille Desjonquères
Human language is combinatorial: phonemes are grouped into syllables, syllables into words, and so on. The capacity for combinatorial processing is present to different degrees in some mammals and birds. We tested for basic combinatorial processing in an insect against two competing hypotheses: beginning rule (where the early signal portions play a stronger role in acceptability); and no rule (where the order of signal elements plays no role in signal acceptability). We worked with Enchenopa...

Avian MHC copy number variation is associated with helminth richness

Piotr Minias, Jorge Gutiérrez & Peter Dunn
Genes of the Major Histocompatibility Complex (MHC) play a key role in the adaptive immunity of vertebrates, as they encode receptors responsible for recognition of antigens. Evolutionary history of the MHC proceeded through numerous gene duplications, which increases the spectrum of pathogens recognized by individuals. Although pathogen-mediated selection is believed to be a primary driver of MHC expansion over evolutionary times, empirical evidence for this association is virtually lacking. Here, we used an extensive dataset...

Juvenile social experience and practice have a switch-like influence on adult mate preferences in an insect

Camille Desjonquères, Jak Maliszewski & Rafael Lucas Rodriguez
Social causes of variation in animal communication systems have important evolutionary consequences, including speciation. The relevance of these effects depends on how widespread they are among animals. There is evidence for such effects not only in birds and mammals, but also frogs and some insects and spiders. Here we analyse the social ontogeny of adult mate preferences in an insect, Enchenopa treehoppers. In these communal plant-feeding insects, individuals reared in isolation or in groups differ...

Data from: Hybrid swarm between divergent lineages of mule deer (Odocoileus hemionus)

Emily K. Latch, Elizabeth M. Kierepka, James R. Heffelfinger &
Studies of hybrid zones have revealed an array of evolutionary outcomes, yet the underlying structure is typically characterized as one of three types: a hybrid zone, a hybrid swarm or a hybrid taxon. Our primary objective was to determine which of these three structures best characterizes a zone of hybridization between two divergent lineages of mule deer (Odocoileus hemionus), mule deer and black-tailed deer. These lineages are morphologically, ecologically and genetically distinct, yet hybridize readily...

Woe is the loner: Female Treefrogs prefer clusters of displaying males over single “hotshot” males

Kane Stratman
Communal displays such as leks and choruses are puzzling phenomena, as it is not obvious why signalers or choosers should aggregate. It has been hypothesized that signalers enjoy higher per capita reproductive success because choosers prefer to sample among dense configurations (“clusters”) that are easier to compare. While female preferences as well as the signal features of attractive males are well characterized in many chorusing species, we know little about how mate sampling is influenced...

Larval yellow perch locations during locomotion assays after exposure to MeHg and PCB126

Janice Albers, Rebekah Klingler, Michael Carvan & Cheryl Murphy
Fish swimming behavior is a commonly measured response in aquatic ecotoxicology because behavior is considered a whole organism-level effect that integrates many sensory systems. Recent advancements in animal behavior models, such as hidden Markov chain models (HMM), suggest an improved analytical approach for toxicology. Using both new and traditional approaches, we examined the sublethal effects of PCB126 and methylmercury on yellow perch (YP) larvae (Perca flavescens) using three doses. Both approaches indicate larvae increase activity...

Data from “Exploring Next Generation Grey” including Questionnaire and Results

Joachim Schopfel, Dominic Farace, David Baxter, Silvia Giannini, ANNA MOLINO, Tomas A. Lipinski, Veronika Potočnik & Dobrica Savic
The GL2021 Conference offered the many and diverse communities of practice in the field of grey literature a unique opportunity to collaborate in addressing and defining the next phase in the digital transformation of grey literature. In preparation for this conference, a panel session on the future of grey literature was planned on the program; and, in advance, an online survey was carried out among GreyNet’s own community of practice in the field of grey...

High MHC diversity confers no advantage for phenotypic quality and reproductive performance in a wild bird

Ewa Pikus, Peter Dunn & Piotr Minias
Genes of the major histocompatibility complex (MHC) encode antigen binding molecules and are an integral part of the acquired immune response of vertebrates. In general, high individual MHC diversity is expected to increase fitness by broadening the spectrum of pathogens recognized by the immune system, in accordance with the heterozygote advantage mechanism. On the other hand, the optimality hypothesis assumes that individuals with optimal (intermediate), rather than maximum diversity of the MHC will achieve the...

Data from: Contrasting patterns of selection on the size and coloration of a female plumage ornament in common yellowthroats

Corey R. Freeman-Gallant, Rebecca L. Schneider, Conor C. Taff, Peter O. Dunn & Linda A. Whittingham
Females often possess ornaments that appear smaller and duller than homologous traits in males. These ornaments may arise as nonfunctional by-products of sexual selection in males and cause negative viability or fecundity selection in females in proportion to the cost of their production and maintenance. Alternatively, female ornaments may function as signals of quality that are maintained by sexual or social selection. In a 4-year study of 83 female common yellowthroats (Geothlypis trichas) and their...

Data from: Spatial distribution of nests constrains the strength of sexual selection in a warbler

Conor C. Taff, Corey R. Freeman-Gallant, Peter O. Dunn & Linda A. Whittingham
In socially monogamous species, extra-pair paternity may increase the strength of inter-sexual selection by allowing males with preferred phenotypes to monopolize matings. Several studies have found relationships between male signals and extra-pair mating, but many others fail to explain variation in extra-pair mating success. A greater appreciation for the role that ecological contingencies play in structuring behavioral processes may help to reconcile contradictory results. We studied extra-pair mating in a spatial context in the common...

Data from: Reproductive strategies and isolation-by-demography in a marine clonal plant along an eutrophication gradient

Silvia Oliva, Javier Romero, Marta Pérez, Pablo Manent, Oriol Mascaró, Ester A. Serrão, Nelson Coelho & Filipe Alberto
Genetic diversity in clonal organisms includes two distinct components, 1) the diversity of genotypes or clones (i.e., genotypic richness) in a population, and 2) that of the alleles (i.e., allelic and gene diversity within populations, and differentiation between populations). We investigated how population differentiation and genotypic components are associated across a gradient of eutrophication in a clonal marine plant. To that end we combined direct measurements of sexual allocation (i.e., flower and seed counts) and...

Data from: Going with the flow: hydrodynamic cues trigger directed escapes from a stalking predator

Lillian J. Tuttle, H. Eve Robinson, Daisuke Takagi, J. Rudi Strickler, Petra H. Lenz & Daniel K. Hartline
In the coevolution of predator and prey, different and less well understood rules for threat-assessment apply to freely suspended organisms than to substrate-dwelling ones. Particularly vulnerable are small prey carried with the bulk movement of a surrounding fluid and thus deprived of sensory information within the bow waves of approaching predators. Some planktonic prey have solved this apparent problem, however. We quantified cues generated by the slow approach of larval clownfish (Amphiprion ocellaris) that triggered...

Data from: Specific alleles at immune genes, rather than genome-wide heterozygosity, are related to immunity and survival in the critically endangered Attwater's prairie-chicken

Zachary W. Bateson, Susan C. Hammerly, Jeff A. Johnson, Michael E. Morrow, Linda A. Whittingham & Peter O. Dunn
The negative effects of inbreeding on fitness are serious concerns for populations of endangered species. Reduced fitness has been associated with lower genome-wide heterozygosity and immune gene diversity in the wild; however, it is rare that both types of genetic measures are included in the same study. Thus, it is often unclear whether the variation in fitness is due to the general effects of inbreeding, immunity-related genes or both. Here, we tested whether genome-wide heterozygosity...

Data from: Male stress response is related to ornamentation but not resistance to oxidative stress in a warbler

Amberleigh E. Henschen, Linda A. Whittingham & Peter O. Dunn
1. Ornaments are thought to honestly signal individual quality to potential mates. Individual quality may include the ability to cope with stress through the production of glucocorticoids (GCs), which help to redirect resources from growth or reproduction to survival during an acute stress response. However, elevated levels of GCs may also increase oxidative stress and reduce immune function. Thus, an important question is whether high quality individuals, with more elaborate ornaments, signal their ability to...

Data from: A range-wide domino effect and resetting of the annual cycle in a migratory songbird

Elizabeth A. Gow, Lauren Burke, David W. Winkler, Samantha M. Knight, Robert G. Clark, Marc Bélisle, Lisha L. Berzins, Tricia Blake, Eli S. Bridge, Russell D. Dawson, Peter O. Dunn, Dany Garant, Geoff Holroyd, Andrew G. Horn, David J.T. Hussell, Olga Lansdorp, Andrew J. Laughlin, Marty L. Leonard, Fanie Pelletier, Dave Shutler, Lynn Siefferman, Caz M. Taylor, Helen Trefry, Carol M. Vleck, David Vleck … & D. Ryan Norris
Latitudinal differences in timing of breeding are well documented but how such differences carry over to influence timing of events in the annual cycle of migratory birds is not well understood. We examined geographic variation in timing of events throughout the year using light-level geolocator tracking data from 133 migratory tree swallows (Tachycineta bicolor) originating from 12 North American breeding populations. A swallow’s breeding latitude influenced timing of breeding, which then carried over to affect...

Data from: The relationship between blood parasites and ornamentation depends on the level of analysis in the common yellowthroat

Amberleigh E. Henschen, Linda A. Whittingham & Peter O. Dunn
The Hamilton–Zuk hypothesis predicts that ornament expression is a signal of the ability of individuals to resist parasite infection. Thus, across a population (i.e. between-individuals) more ornamented individuals should have lower levels of parasitism. Numerous studies have tested this prediction and the results are mixed. One reason for these conflicting results may be that many studies have examined this relationship at the between-individual level, which may be affected by confounding factors such as selective mortality....

Data from: The evolution of experience-mediated plasticity in mate preferences

Kasey D. Fowler-Finn & Rafael L. Rodriguez
Experience of sexual signals can alter mate preferences and influence the course of sexual selection. Here, we examine patterns of experience-mediated plasticity in mate preferences that can arise in response to variation in the composition of mates in the environment. We use these patterns to test hypotheses about potential sources of selection favouring experience-mediated plasticity. We manipulated signal experience of female Enchenopa treehoppers (Hemiptera: Membracidae) in a vibrational playback experiment with the following treatments: silence;...

Data from: Fine-scale landscape genetics of the American badger (Taxidea taxus): disentangling landscape effects and sampling artifacts in a poorly understood species

Elizabeth M. Kierepka & Emily K. Latch
Landscape genetics is a powerful tool for conservation because it identifies landscape features that are important for maintaining genetic connectivity between populations within heterogeneous landscapes. However, using landscape genetics in poorly understood species presents a number of challenges, namely, limited life history information for the focal population and spatially biased sampling. Both obstacles can reduce power in statistics, particularly in individual-based studies. In this study, we genotyped 233 American badgers in Wisconsin at 12 microsatellite...
