Training on dsRNA bio manufacturing and management of cowpea bruchid Callosobruchus maculatus on stored cowpea in Kano, Nigeria

Abou TOGOLA, Alison Nwokeoji & Boukar Ousmane
The proposed is a multidisciplinary project for development of a novel RNA-based crop protection strategy for managing cowpea pests. The RNA biopesticides have the potential for use in the management of a wide range of insect pests and pathogens but we will focus on the design and biomanufacturing of novel RNA based pesticides to target the cowpea pod borer (Maruca vitrata). Maruca vitrata Fabricius (Lepidoptera: Crambidae) the most damaging pest of cowpea at podding stage....

Modelled potential carbon storage based on land cover and published carbon storage values in urban landscapes of the South Midlands

D.R. Grafius, R. Corstanje & J. A. Harris
This dataset shows potential carbon storage as modelled for the urban areas of Milton Keynes/Newport Pagnell, Bedford, and Luton/Dunstable, UK. The modelling approach used the ‘InVEST (Integrated Valuation of Ecosystem Services and Trade-offs) 3.1.0’ ecosystem service model suite, raster land cover maps at two spatial resolutions (5 m and 25 m) and published literature values for carbon storage by land cover. The resulting data are presented in the form of two ‘GeoTIFF’ raster map files...

Arbuscular mycorrhizal fungi diversity data from a grassland microcosm experiment [NERC Soil Biodiversity Programme]

D. Johnson, P.J. Vandenkoornhuyse, J.R. Leake, L. Gilbert, , J.P Grime, J.P.W. Young & D.J. Read
These arbuscular mycorrhizal (AM) fungi diversity data were collected in 2000 as part of an investigation in an unfertilized limestone grassland soil supporting different synthesized vascular plant assemblages that had developed for three years. The experimental treatments comprised: bare soil; monocultures of the non mycotrophic sedge Carex flacca; monocultures of the mycotrophic grass Festuca ovina; and a species-rich mixture of four forbs, four grasses and four sedges. The experiment was undertaken in microcosms, set up...

Data from: Preston’s universal formula for avian egg shape

John D Biggins, Robert Montgomerie, Jamie Thompson & Tim Birkhead
The main data are 50 photographs of eggs, one from each of 50 species. 25 of these species have pyriform eggs, based on the traditional usage of this descriptive term. The photographs were taken to allow an investigation of egg shape, so they are lit from behind to provide a clear silhouete and were arranged to have the plane containing their longest axis parallel to the 'film' plane. A csv file contains basic information about...

Data from: Social and spatial effects on genetic variation between foraging flocks in a wild bird population

Reinder Radersma, Colin J. Garroway, Anna W. Santure, Isabelle De Cauwer, Damien R. Farine, Jon Slate & Ben C. Sheldon
Social interactions are rarely random. In some instances animals exhibit homophily or heterophily, the tendency to interact with similar or dissimilar conspecifics respectively. Genetic homophily and heterophily influence the evolutionary dynamics of populations, because they potentially affect sexual and social selection. Here we investigate the link between social interactions and allele frequencies in foraging flocks of great tits (Parus major) over three consecutive years. We constructed co-occurrence networks which explicitly described the splitting and merging...

Data from: Whole-genome patterns of linkage disequilibrium across flycatcher populations clarify the causes and consequences of fine-scale recombination rate variation in birds

Takeshi Kawakami, Carina F. Mugal, Alexander Suh, Alexander Nater, Reto Burri, Linnea Smeds & Hans Ellegren
Recombination rate is heterogeneous across the genome of various species, and so are genetic diversity and differentiation as a consequence of linked selection. However, we still lack a clear picture of the underlying mechanisms for regulating recombination. Here we estimated fine-scale population recombination rate based on the patterns of linkage disequilibrium (LD) across the genomes of multiple populations of two closely related flycatcher species (Ficedula albicollis and F. hypoleuca). This revealed an overall conservation of...

Data from: Recent natural selection causes adaptive evolution of an avian polygenic trait

Mirte Bosse, Lewis G. Spurgin, Veronika N. Laine, Ella F. Cole, Josh A. Firth, Phillip Gienapp, Andrew G. Gosler, Keith McMahon, Jocelyn Poissant, Irene Verhagen, Martien A. M. Groenen, Kees Van Oers, Ben C. Sheldon, Marcel E. Visser & Jon Slate
We used extensive data from a long-term study of great tits (Parus major) in the United Kingdom and Netherlands to better understand how genetic signatures of selection translate into variation in fitness and phenotypes. We found that genomic regions under differential selection contained candidate genes for bill morphology and used genetic architecture analyses to confirm that these genes, especially the collagen gene COL4A5, explained variation in bill length. COL4A5 variation was associated with reproductive success,...

Data from: Accurately quantifying the shape of birds' eggs

John D. Biggins, Jamie E. Thompson & Tim R. Birkhead
Describing the range of avian egg shapes quantitatively has long been recognised as difficult. A variety of approaches has been adopted, some of which aim to capture the shape accurately and some to provide intelligible indices of shape. The objectives here are to show that a (four-parameter) method proposed by Preston (1953) is the best option for quantifying egg shape, to provide and document an R program for applying this method to suitable photographs of...

Data from: Are assortative mating and genital divergence driven by reinforcement?

Johan Hollander, Mauricio Montaño-Rendón, Giuseppe Bianco, Xi Yang, Anja M. Westram, Ludovic Duvaux, David G. Reid & Roger K. Butlin
The evolution of assortative mating is a key part of the speciation process. Stronger assortment, or greater divergence in mating traits, between species pairs with overlapping ranges is commonly observed, but possible causes of this pattern of reproductive character displacement are difficult to distinguish. We use a multidisciplinary approach to provide a rare example where it is possible to distinguish among hypotheses concerning the evolution of reproductive character displacement. We build on an earlier comparative...

Data from: Detecting genes for variation in parasite burden and immunological traits in a wild population: testing the candidate gene approach

Emily A. Brown, Jill G. Pilkington, Dan H. Nussey, Kathryn A. Watt, Adam D. Hayward, Rachel Tucker, Andrea L. Graham, Steve Paterson, Dario Beraldi, Josephine M. Pemberton & Jon Slate
Identifying the genes underlying phenotypic variation in natural populations can provide novel insight into the evolutionary process. Here we test the candidate gene approach to identifying loci involved in variation in gastrointestinal parasite burden, in a wild population of Soay sheep. A comprehensive literature review, Gene Ontology databases, and comparative genomics resources were used to generate a list of candidate genes. In a pilot study these candidates, along with 50 random genes, were then sequenced...

Data from: Replicated high-density genetic maps of two great tit populations reveal fine-scale genomic departures from sex-equal recombination rates

Kees Van Oers, Anna W. Santure, Isabelle De Cauwer, Nikkie E. M. Van Bers, Richard P. M. A. Crooijmans, Ben C. Sheldon, Marcel E. Visser, Jon Slate & Martien A. M. Groenen
Linking variation in quantitative traits to variation in the genome is an important, but challenging task in the study of life-history evolution. Linkage maps provide a valuable tool for the unravelling of such trait-gene associations. Moreover, they give insight into recombination landscapes and between- species karyotype evolution. Here we used genotype data, generated from a 10k SNP-chip, of over 2000 individuals to produce high-density linkage maps of the great tit (Parus major), a passerine bird,...

Data from: Increased survival of experimentally evolved antimicrobial peptide-resistant Staphylococcus aureus in an animal host

Adam J. Dobson, Joanne Purves & Jens Rolff
Antimicrobial peptides (AMPs) have been proposed as new class of antimicrobial drugs, following the increasing prevalence of bacteria resistant to antibiotics. Synthetic AMPs are functional analogues of highly evolutionarily conserved immune effectors in animals and plants, produced in response to microbial infection. Therefore, the proposed therapeutic use of AMPs bears the risk of ‘arming the enemy’: bacteria that evolve resistance to AMPs may be cross-resistant to immune effectors (AMPs) in their hosts. We used a...

Data from: Less favorable climates constrain demographic strategies in plants

Anna M. Csergo, Roberto Salguero-Gómez, Olivier Broennimann, Shaun R. Coutts, Antoine Guisan, Amy L. Angert, Erik Welk, Iain Stott, Brian J. Enquist, Brian McGill, Jens-Christian Svenning, Cyrille Violle & Yvonne M. Buckley
Correlative species distribution models are based on the observed relationship between species’ occurrence and macroclimate or other environmental variables. In climates predicted less favourable populations are expected to decline, and in favourable climates they are expected to persist. However, little comparative empirical support exists for a relationship between predicted climate suitability and population performance. We found that the performance of 93 populations of 34 plant species worldwide – as measured by in situ population growth...

Data from: Phylogeny and generic delimitation in Molluginaceae, new pigment data in Caryophyllales, and the new family Corbichoniaceae

Mats Thulin, Abigail J. Moore, Hesham El-Seedi, Anders Larsson, Pascal-Antoine Christin & Erika J. Edwards
The circumscription of Molluginaceae has changed radically in recent years, with Corbichonia being moved to Lophiocarpaceae, Limeum to Limeaceae, Macarthuria to Macarthuriaceae and all species of Hypertelis, except the type, to Kewa in Kewaceae. In a broad analysis of core Caryophyllales using plastid trnK-matK and rbcL sequences, the position of Molluginaceae in a strict sense as sister to the Portulacineae clade is corroborated, as are the positions of Corbichonia, Limeum and Kewa outside the family....

Data from: Genomic differentiation during speciation-with-gene-flow: comparing geographic and host-related variation in divergent life history adaptation in Rhagoletis pomonella

Meredith M. Doellman, Gregory J. Ragland, Glen R. Hood, Peter J. Meyers, Scott P. Egan, Thomas H.Q. Powell, Peter Lazorchak, Mary M. Glover, Cheyenne Tait, Hannes Schuler, Daniel A. Hahn, Stewart H. Berlocher, James J. Smith, Patrik Nosil, Jeffrey L. Feder, Daniel Hahn, Stewart Berlocher, Peter Meyers, Scott Egan, Jeffrey Feder, Glen Hood, Thomas Powell & Gregory Ragland
A major goal of evolutionary biology is to understand how variation within populations gets partitioned into differences between reproductively isolated species. Here, we examine the degree to which diapause life history timing, a critical adaptation promoting population divergence, explains geographic and host-related genetic variation in ancestral hawthorn and recently derived apple-infesting races of Rhagoletis pomonella. Our strategy involved combining experiments on two different aspects of diapause (initial diapause intensity and adult eclosion time) with a...

Data from: Interacting livestock and fire may both threaten and increase viability of a fire-adapted Mediterranean carnivorous plant

Maria Paniw, Pedro F. Quintana-Ascencio, Fernando Ojeda & Roberto Salguero-Gomez
1. Quantifying interactive effects of environmental drivers on population dynamics can be critical for a robust analysis of population viability. Fire regimes, among the most widespread disturbances driving population dynamics, are increasingly modified by and interact with human activities. However, viability of fire-adapted species is typically assessed overlooking disturbance interactions, potentially resulting in suboptimal management actions. 2. We investigated whether increasing human disturbances in fire-prone ecosystems may pose a threat or an opportunity to improve...

Data from: Polygamy slows down population divergence in shorebirds

Josephine D'Urban Jackson, Natalie Dos Remedios, Kathryn H. Maher, Sama Zefania, Susan Haig, Sara Oyler-McCance, Donald Blomqvist, Terry Burke, Mike W. Bruford, Tamas Szekely, Clemens Küpper & Michael W. Bruford
Sexual selection may act as a promotor of speciation since divergent mate choice and competition for mates can rapidly lead to reproductive isolation. Alternatively, sexual selection may also retard speciation since polygamous individuals can access additional mates by increased breeding dispersal. High breeding dispersal should hence increase gene flow and reduce diversification in polygamous species. Here we test how polygamy predicts diversification in shorebirds using genetic differentiation and subspecies richness as proxies for population divergence....

Data from: Spatial heterogeneity lowers rather than increases host-parasite specialization

Elze Hesse, Alex Best, Michael Boots, Alex R. Hall & Angus Buckling
Abiotic environmental heterogeneity can promote the evolution of diverse resource specialists, which in turn may increase the degree of host-parasite specialization. We coevolved Pseudomonas fluorescens and lytic phage ϕ2 in spatially structured populations, each consisting of two interconnected subpopulations evolving in the same or different nutrient media (homogeneous and heterogeneous environments, respectively). Counter to the normal expectation, host-parasite specialization was significantly lower in heterogeneous compared with homogeneous environments. This result could not be explained by...
