Using Decorative Elements to Refine the Relationship Between Two Ælfrician Manuscripts

Emily Rae
Items from Ælfric’s First Series of Catholic Homilies survive in thirty-four manuscripts and manuscript fragments. Because of their complex histories, and our incomplete modern knowledge of their production and dissemination, we still have only a limited understanding of the exact relationship between all copies of the First Series texts. In the past, scholarship has determined manuscript relationships based primarily on textual collation, rather than by considering physical aspects of the manuscripts themselves. This article demonstrates...

Genetic evidence further elucidates the history and extent of badger introductions from Great Britain into Ireland

Adrian Allen, Jimena Guerrero, Andrew Byrne, John Lavery, Eleanor Presho, Emily Courcier, James O'Keeffe, Ursula Fogarty, Richard Delahay, Gavin Wilson, Chris Newman, Christina Buesching, Matthew Silk, Denise O'Meara, Robin Skuce, Roman Biek & Robbie A. McDonald
The colonization of Ireland by mammals, has been the subject of extensive study using genetic methods, and forms a central problem in understanding the phylo-geography of European mammals after the Last Glacial Maximum. Ireland exhibits a de-pauperate mammal fauna relative to Great Britain and continental Europe, and a range of natural and anthropogenic processes have given rise to its modern fauna. Previous Europe-wide surveys of the European badger (Meles meles) have found conflicting microsatellite and...

We are what we eat, plus some per mill: Using stable isotopes to estimate diet composition in Gyps vultures over space and time

Allan Baino, Grant Hopcraft, Corinne Kendall, Linus Munishi, Abdelkader Behdenna, Jason Newton & Thomas Morrison
1. Dietary studies in birds of prey involve direct observation and examination of food remains at resting and nesting sites. Although these methods accurately identify diet in raptors, they are time consuming, resource intensive and associated with biases that stem from the feeding ecology of raptors like Gyps vultures (Gyps africanus and Gyps rueppelli). Our study set out to estimate diet composition in Gyps vultures informed by stable isotopes that provide a good representation of...

Telomeres and anthropogenic disturbances in wildlife: a systematic review and meta-analysis

Pablo Salmón & Pablo Burraco
Human-driven environmental changes are affecting wildlife across the globe. These challenges do not influence species or populations to the same extent and therefore, a comprehensive evaluation of organismal health is needed to determine their ultimate impact. Evidence suggests that telomeres (the terminal chromosomal regions) are sensitive to environmental conditions and have been posited as a surrogate for animal health and fitness. Evaluation of their use in an applied ecological context is still scarce. Here, using...

Data from: Continent-level drivers of African pyrodiversity

Gareth P. Hempson, Catherine L. Parr, Sally Archibald, T. Michael Anderson, Colin J. Courtney Mustaphi, Andrew P. Dobson, Jason E. Donaldson, Thomas A. Morrison, James Probert & Colin M. Beale
Pyrodiversity, which describes fire variability over space and time, is believed to increase habitat heterogeneity and thereby promote biodiversity. However, to date there is no standardised metric for quantifying pyrodiversity, and so broad geographic patterns and drivers of pyrodiversity remain unexplored. We present the first generalizable method to quantify pyrodiversity, and use it to address the fundamental questions of what drives pyrodiversity, which fire attributes constrain pyrodiversity under different conditions, and whether pyrodiversity is spatial...

Data from: Eye coding mechanisms in early human face event-related potentials

Guillaume A. Rousselet, Robin A. A. Ince, Nicola J. Van Rijsbergen & Philippe G. Schyns
In humans, the N170 event-related potential (ERP) is an integrated measure of cortical activity that varies in amplitude and latency across trials. Researchers often conjecture that N170 variations reflect cortical mechanisms of stimulus coding for recognition. Here, to settle the conjecture and understand cortical information processing mechanisms, we unraveled the coding function of N170 latency and amplitude variations in possibly the simplest socially important natural visual task: face detection. On each experimental trial, 16 observers...

Data from: Evidence of land-sea transfer of the zoonotic pathogen Campylobacter to a wildlife marine sentinel species

Johanna L. Baily, Guillaume Méric, Sion Bayliss, Geoffrey Foster, Simon E. Moss, Eleanor Watson, Ben Pascoe, Jane Mikhail, Robert J. Goldstone, Romain Pizzi, David G. E. Smith, Kim Willoughby, Alisa J. Hall, Mark P. Dagleish, Samuel K. Sheppard & Ailsa J. Hall
Environmental pollution often accompanies the expansion and urbanization of human populations where sewage and wastewaters commonly have an impact on the marine environments. Here, we explored the potential for faecal bacterial pathogens, of anthropic origin, to spread to marine wildlife in coastal areas. The common zoonotic bacterium Campylobacter was isolated from grey seals (Halichoerus grypus), an important sentinel species for environmental pollution, and compared to isolates from wild birds, agricultural sources and clinical samples to...

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: Mosaic VSGs and the scale of Trypanosoma brucei antigenic variation

James P. J. Hall, Huanhuan Wang & J. David Barry
A main determinant of prolonged Trypanosoma brucei infection, and hence transmission and success of the parasite, is the interplay between host acquired immunity and antigenic variation of the parasite variant surface glycoprotein (VSG) coat. About 0.1% of trypanosome divisions produce a switch to a different VSG through differential expression of an archive of hundreds of silent VSG genes and pseudogenes, but the patterns and extent of the trypanosome diversity phenotype, particularly in chronic infection, are...

Data from: Double-digest RAD Sequencing using Ion Proton semiconductor platform (ddRADseq-ion) with non-model organisms

Hans Recknagel, Arne Jacobs, Pawel Herzyk & Kathryn R. Elmer
Research in evolutionary biology involving nonmodel organisms is rapidly shifting from using traditional molecular markers such as mtDNA and microsatellites to higher throughput SNP genotyping methodologies to address questions in population genetics, phylogenetics and genetic mapping. Restriction site associated DNA sequencing (RAD sequencing or RADseq) has become an established method for SNP genotyping on Illumina sequencing platforms. Here, we developed a protocol and adapters for double-digest RAD sequencing for Ion Torrent (Life Technologies; Ion Proton,...

Data from: Are molecular markers useful predictors of adaptive potential?

Elizabeth A. Mittell, Shinichi Nakagawa & Jarrod D. Hadfield
Estimates of molecular genetic variation are often used as a cheap and simple surrogate for a population's adaptive potential, yet empirical evidence suggests they are unlikely to be a valid proxy. However, this evidence is based on molecular genetic variation poorly predicting estimates of adaptive potential rather than how well it predicts true values. As a consequence, the relationship has been systematically underestimated and the precision with which it could be measured severely overstated. By...

Reservoir dynamics of rabies in Southeast Tanzania and the roles of cross-species transmission and domestic dog vaccination

Kennedy Lushasi, Sarah Hayes, Elaine A Ferguson, Joel Changalucha, Sarah Cleaveland, Nicodem J Govella, Daniel T Haydon, Sambo Maganga, Geofrey J Mchau, Emmanuel A Mpolya, Zacharia Mtema, Hesron E Nonga, Rachel Steenson, Pierre Nouvellet, Christl A Donnelly & Katie Hampson
Understanding the role of different species in the transmission of multi-host pathogens, such as rabies virus, is vital for effective control strategies. Across most of sub-Saharan Africa domestic dogs (Canis familiaris) are considered the reservoir for rabies, but the role of wildlife has been long debated. Here we explore the multi-host transmission dynamics of rabies across southeast Tanzania. Between January 2011 and July 2019 data on probable rabies cases were collected in the regions of...

Objective To test the genetic contribution of rare missense variants in COL4A1 and COL4A2 in which common variants are genetically associated with sporadic intracerebral hemorrhage (ICH), we performed rare variant analysis in multiple sequencing data for the risk for sporadic ICH. Methods We performed sequencing across 559Kbp at 13q34 including COL4A1 and COL4A2 among 2,133 individuals (1,055 ICH cases; 1,078 controls) in US-based and 1,492 individuals (192 ICH cases; 1,300 controls) from Scotland-based cohorts, followed...

Color of artificial light at night affects incubation behavior in the great tit, Parus major

Natalie Van Dis, Kamiel Spoelstra, Marcel Visser & Davide Dominoni
Artificial light at night (ALAN) has been recognized as a biodiversity threat due to the drastic effects it can have on many organisms. In wild birds, artificial illumination alters many natural behaviors that are important for fitness, including chick provisioning. Although incubation is a key determinant of the early developmental environment, studies into the effects of ALAN on bird incubation behavior are lacking. We measured nest temperature in nest boxes of great tits during the...

Data from: High heritability of telomere length and low heritability of telomere shortening in wild birds

Christina Bauch, Jelle J. Boonekamp, Peter Korsten, Ellis Mulder & Simon Verhulst
Telomere length and telomere shortening predict survival in many organisms. This raises the question of the contribution of genetic and environmental effects to variation in these traits, which is still poorly known, particularly for telomere shortening. We used experimental (cross-fostering) and statistical (quantitative genetic ‘animal’ models) means to disentangle and estimate genetic and environmental contributions to telomere length variation in pedigreed free-living jackdaws (Corvus monedula). Telomere length was measured twice in nestlings, at ages 4...

Diet and temperature modify the relationship between energy use and ATP production to influence behaviour in zebrafish (Danio rerio)

Amélie Le Roy, Geoffrey Mazué, Neil Metcalfe & Frank Seebacher
Food availability and temperature influence energetics of animals, and can alter behavioural responses such as foraging and spontaneous activity. Food availability, however, is not necessarily a good indictator of energy (ATP) available for cellular processes. The efficiency of energy transduction from food-derived substrate to ATP in mitochondria can change with environmental context. Our aim was to determine whether the interaction between food availability and temperature affects mitochondrial efficiency and behaviour in zebrafish (Danio rerio). We...
