Data from: ‘Venus trapped, Mars transits’: Cu and Fe redox chemistry, cellular topography and in situ ligand binding in terrestrial isopod hepatopancreas

Peter Kille, A. John Morgan, Kate Powell, J. Frederick W. Mosselmans, Daniel Hart, Paul Gunning, Anthony Hayes, Derek Scarborough, Iain Mcdonald & John M. Charnock
Woodlice efficiently sequester copper (Cu) in ‘cuprosomes’ within hepatopancreatic ‘S’ cells. Binuclear ‘B’ cells in the hepatopancreas form iron (Fe) deposits; these cells apparently undergo an apocrine secretory diurnal cycle linked to nocturnal feeding. Synchrotron-based m-focus X-ray spectroscopy undertaken on thin sections was used to characterize the ligands binding Cu and Fe in S and B cells of Oniscus asellus (Isopoda). Main findings were: (i) morphometry confirmed a diurnal B-cell apocrine cycle; (ii) X-ray fluorescence...

Data from: Landscape determinants of fine-scale genetic structure of a small rodent in a heterogeneous landscape (Hluhluwe-iMfolozi Park, South Africa)

Isa-Rita M. Russo, Catherine L. Sole, Mario Barbato, Ullrich Von Bramann & Michael W. Bruford
Small mammals provide ecosystem services, acting, for example, as pollinators and seed dispersers. In addition, they are also disease reservoirs that can be detrimental to human health and they can also act as crop pests. Knowledge of their dispersal preferences is therefore useful for population management and landscape planning. Genetic data were used alongside landscape data to examine the influence of the landscape on the demographic connectedness of the Natal multimammate mouse (Mastomys natalensis) and...

Data from: No signs of inbreeding despite long-term isolation and habitat fragmentation in the critically endangered Montseny brook newt (Calotriton arnoldi)

Emilio Valbuena-Ureña, Anna Soler-Membrives, Sebastian Steinfartz, Pablo Orozco-TerWengel & Salvador Carranza
Endemic species with restricted geographic ranges potentially suffer the highest risk of extinction. If these species are further fragmented into genetically isolated subpopulations, the risk of extinction is elevated. Habitat fragmentation is generally considered to have negative effects on species survival, despite some evidence for neutral or even positive effects. Typically, non-negative effects are ignored by conservation biology. The Montseny brook newt (Calotriton arnoldi) has one of the smallest distribution ranges of any European amphibian...

Data from: Imprinting can cause a maladaptive preference for infectious conspecifics

Jessica F. Stephenson & Michael Reynolds
Recognizing and associating with specific individuals, such as conspecifics or kin, brings many benefits. One mechanism underlying such recognition is imprinting: the long-term memory of cues encountered during development. Typically, juveniles imprint on cues of nearby individuals and may later associate with phenotypes matching their ‘recognition template’. However, phenotype matching could lead to maladaptive social decisions if, for instance, individuals imprint on the cues of conspecifics infected with directly transmitted diseases. To investigate the role...

Data from: The effects of supplementary food on the breeding performance of Eurasian reed warblers Acrocephalus scirpaceus; implications for climate change impacts

James O. Vafidis, Ian P. Vaughan, T. Hefin Jones, Richard J. Facey, Rob Parry & Robert J. Thomas
Understanding the mechanisms by which climate variation can drive population changes requires information linking climate, local conditions, trophic resources, behaviour and demography. Climate change alters the seasonal pattern of emergence and abundance of invertebrate populations, which may have important consequences for the breeding performance and population change of insectivorous birds. In this study, we examine the role of food availability in driving behavioural changes in an insectivorous migratory songbird; the Eurasian reed warbler Acrocephalus scirpaceus....

Data from: A further cost for the sicker sex? Evidence for male-biased parasite-induced vulnerability to predation

Jessica F. Stephenson, Cormac Kinsella, Joanne Cable & Cock Van Oosterhout
Males are typically the sicker sex. Data from multiple taxa indicate that they are more likely to be infected with parasites, and are less “tolerant,” or less able to mitigate the fitness costs of a given infection, than females. One cost of infection for many animals is an increased probability of being captured by a predator. A clear, hitherto untested, prediction is therefore that this parasite-induced vulnerability to predation is more pronounced among males than...

Data from: Gene duplication and divergence produce divergent MHC genotypes without disassortative mating

Donald C. Dearborn, Andrea B. Gager, Andrew G. McArthur, Morgan E. Gilmour, Elena Mandzhukova & Robert A. Mauck
Genes of the major histocompatibility complex (MHC) exhibit heterozygote advantage in immune defence, which in turn can select for MHC-disassortative mate choice. However, many species lack this expected pattern of MHC-disassortative mating. A possible explanation lies in evolutionary processes following gene duplication: if two duplicated MHC genes become functionally diverged from each other, offspring will inherit diverse multilocus genotypes even under random mating. We used locus-specific primers for high-throughput sequencing of two expressed MHC Class...

Flame retardants in the livers of the Eurasian otter collected from Scotland between 2013 and 2015 (PBMS)

L.A. Walker, C. Moeckel, M.G. Pereira, E.D. Potter, E.A. Chadwick & R.F. Shore
Data comprise concentrations of polybrominated diphenyl ethers (PBDEs) determined using Gas Chromatograph - Mass Spectrometry (GC-MS) in the liver tissue of a small sample of Eurasian otters (Lutra lutra) that died in Scotland between 2013 and 2015. The otters analysed included adult and sub-adult males and females although there were insufficient sample numbers to test for differences among demographic groups. Otter liver tissue collected during post mortem by Cardiff University Otter Project (from otters found...

Data from: Women are seen more than heard in online newspapers

Sen Jia, Thomas Lansdall-Welfare, Saatviga Sudhahar, Cynthia Carter & Nello Cristianini
Feminist news media researchers have long contended that masculine news values shape journalists’ quotidian decisions about what is newsworthy. As a result, it is argued, topics and issues traditionally regarded as primarily of interest and relevance to women are routinely marginalised in the news, while men’s views and voices are given privileged space. When women do show up in the news, it is often as “eye candy,” thus reinforcing women’s value as sources of visual...

Data from: Hybridization relics complicate barcode-based identification of species in earthworms

Lise Dupont, David Porco, William O. C. Symondson & Virginie Roy
Introgressive hybridization results in mito-nuclear discordance which could obscure the delimitation of closely related taxa. Although such events are increasingly reported, they have been poorly studied in earthworms. Here, we propose a method for investigating the degree of introgressive hybridization between three taxa of the Allolobophora chlorotica aggregate within two field populations (N = 67 and N = 105) using a reference dataset including published DNA barcoding and microsatellite data of all known A. chlorotica...

Data from: Comparative genomics to explore phylogenetic relationship, cryptic sexual potential and host specificity of Rhynchosporium species on grasses

Daniel Penselin, Martin Muensterkoetter, Susanne Kirsten, Marius Felder, Stefan Taudien, Matthias Platzer, Kevin Ashelford, Konrad H. Paskiewicz, Richard J. Harrison, David J. Hughes, Thomas Wolf, Ekaterina Shelest, Jenny Graap, Jan Hoffmann, Claudia Wenzel, Nadine Woeltje, Kevin M. King, Bruce D. L. Fitt, Ulrich Gueldener, Anna Avrova & Wolfgang Knogge
Background: The Rhynchosporium species complex consists of hemibiotrophic fungal pathogens specialized to different sweet grass species including the cereal crops barley and rye. A sexual stage has not been described, but several lines of evidence suggest the occurrence of sexual reproduction. Therefore, a comparative genomics approach was carried out to disclose the evolutionary relationship of the species and to identify genes demonstrating the potential for a sexual cycle. Furthermore, due to the evolutionary very young...
