Data from: Temperature-dependent resetting of the molecular circadian oscillator in Drosophila.

Tadahiro Goda, Brandi Sharp & Herman Wijnen
Circadian clocks responsible for daily time keeping in a wide range of organisms synchronize to daily temperature cycles via pathways that remain poorly understood. To address this problem from the perspective of the molecular oscillator, we monitored temperature-dependent resetting of four of its core components in the fruitfly Drosophila melanogaster: the transcripts and proteins for the clock genes period (per) and timeless (tim). The molecular circadian cycle in adult heads exhibited parallel responses to temperature-mediated...

Data from: Sustained miniaturization and anatomical innovation in the dinosaurian ancestors of birds

Andrea Cau, Gareth J. Dyke, Michael S. Y. Lee & Darren Naish
Recent discoveries have highlighted the dramatic evolutionary transformation of massive, ground-dwelling theropod dinosaurs into light, volant birds. Here, we apply Bayesian approaches (originally developed for inferring geographic spread and rates of molecular evolution in viruses) in a different context: to infer size changes and rates of anatomical innovation (across up to 1549 skeletal characters) in fossils. These approaches identify two drivers underlying the dinosaur-bird transition. The theropod lineage directly ancestral to birds undergoes sustained miniaturization...

Data from: Mechanisms of biotic resistance across complex life cycles

Marc Rius, Elaine E. Potter, John J. Stachowicz & J. David Aguirre
1. Biotic resistance is the ability of communities to inhibit the establishment, spread or impact of novel species. However, the interactions that underlie biotic resistance depend heavily on the contexts in which species interact. Consequently, studies of biotic resistance that consider single processes, patches, species or life-history stages may provide an incomplete picture of the capacity for communities to resist invasion. 2. Many organisms have multiphasic life cycles, where individuals can occupy distinct niches at...

Global Soybean Trade – The Geopolitics of a Bean

Marcello De Maria, Elizabeth Robinson, Joseph Rajabu Kangile, Reuben MJ Kadigi, Ilda Dreoni, Matheus Couto, Niko Howai, Jurgen Peci & Sicily Fiennes
This report, which is the result of collaborative effort within the Trade Hub project, explores the multiplicity of issues associated with the so-called ‘soybean miracle’, both from a global and a local perspective. With a comprehensive review of the available literature and data, and with country-specific summaries for Tanzania, Brazil and China, this study retraces the historical moments that contributed to make soybean a ‘global flexible crop’, increasingly appreciated and demanded for its versatility all...

Cavitation Clusters in Lipid Systems – The Generation of a Bifurcated Streamer and the Dual Collapse of a Bubble Cluster

Silvana Martini, Peter Birkin & Tadd T. Truscott
Over the past decade several studies have reported the use of high intensity ultrasound (HIU) to induce the crystallization of lipids. The effect that HIU has on lipid crystallization is usually attributed to the generation of cavities but acoustic cavitation has never been fully explored in lipids. The dynamics of a particular cavitation cluster next to a piston like emitter in an oil, was investigated in this study. The lipid systems, which are important in...

Data from: The architecture of an empirical genotype-phenotype map

Jose Aguilar-Rodriguez, Leto Peel, Massimo Stella, Andreas Wagner & Joshua L. Payne
Recent advances in high-throughput technologies are bringing the study of empirical genotype-phenotype (GP) maps to the fore. Here, we use data from protein binding microarrays to study an empirical GP map of transcription factor (TF) binding preferences. In this map, each genotype is a DNA sequence. The phenotype of this DNA sequence is its ability to bind one or more TFs. We study this GP map using genotype networks, in which nodes represent genotypes with...

Data from: Epigenome-wide association study of lung function level and its change

Medea Imboden, Matthias Wielscher, Faisal I Rezwan, Andre F S Amaral, Emmanuel Schaffner, Ayoung Jeong, Anna Beckmeyer-Borowko, Sarah E Harris, John M Starr, Ian J Deary, Claudia Flexeder, Melanie Waldenberger, Annette Peters, Holger Schulz, Su Chen, Shadia KHan Sunny, Wilfried J J Karmaus, Yu Jiang, Gertraud Erhart, Florian Kronenberg, Ryan Arathimos, Gemma C Sharp, Alexander John Henderson, Yu Fu, Paivi Piirila … & Nicole M Probst-Hensch
Previous reports link differential DNA methylation (DNAme) to environmental exposures which are associated with lung function. Direct evidence on lung function DNAme is however limited. We undertook an agnostic epigenome-wide association study (EWAS) on pre-bronchodilation lung function and its change in adults. In a discovery-replication EWAS design, DNAme in blood and spirometry were measured twice, six-to-15 years apart, in the same participants of three adult population-based discovery cohorts (n=2,043). Associated DNAme markers (P<5x10-7) were tested...

Data from: Comparative population genomics reveals key barriers to dispersal in Southern Ocean penguins

Gemma V. Clucas, Jane L. Younger, Damian Kao, Louise Emmerson, Colin Southwell, Barbara Wienecke, Alex D. Rogers, Charles-Andre Bost, Gary D. Miller, Michael J. Polito, Patrick Lelliot, Jonathan Handley, Sarah Crofts, Richard A. Phillips, Michael J. Dunn, Karen J. Miller, Tom Hart & Patrick Lelliott
The mechanisms that determine patterns of species dispersal are important factors in the production and maintenance of biodiversity. Understanding these mechanisms helps to forecast the responses of species to environmental change. Here we used a comparative framework and genome-wide data obtained through RAD-seq to compare the patterns of connectivity among breeding colonies for five penguin species with shared ancestry, overlapping distributions, and differing ecological niches, allowing an examination of the intrinsic and extrinsic barriers governing...

Data from: How group composition affects cooperation in fixed networks: can psychopathic traits influence group dynamics?

Martina Testori, Rebecca B. Hoyle & Hedwig Eisenbarth
Static networks have been shown to foster cooperation for specific cost-benefit ratios and numbers of connections across a series of interactions. At the same time, psychopathic traits have been discovered to predict defective behaviours in game theory scenarios. This experiment combines these two aspects to investigate how group cooperation can emerge when changing group compositions based on psychopathic traits. We implemented a modified version of the Prisoner’s Dilemma game which has been demonstrated theoretically and...

Data from: Recording and reproducing the diurnal oviposition rhythms of wild populations of the soft- and stone- fruit pest Drosophila suzukii

Bethan Shaw, Fountain T. Michelle, Wijnen Herman & Herman Wijnen
Drosophila suzukii is a horticultural pest on a global scale which causes both yield and economic losses on a range of soft- and stone-fruit. Tackling this pest is problematic but exploiting behavioural rhythms could increase the impact of control. To do this, a better understanding of behavioural patterns is needed. Within this study we aimed to investigate rhythms in reproductive behaviour of wild D. suzukii under natural conditions in the field. Environmental parameters were also...

Data from: First measurements of field metabolic rate in wild juvenile fishes show strong thermal sensitivity but variations between sympatric ecotypes

Ming-Tsung Chung, Kris‐Emil Mose Jørgensen, Clive N. Trueman, Halvor Knutsen, Per Erik Jorde & Peter Grønkjær
The relationship between physiology and temperature has a large influence on population-level responses to climate change. In natural settings, direct thermal effects on metabolism may be exaggerated or offset by behavioural responses influencing individual energy balance. Drawing on a newly developed proxy, we provide the first estimates of the thermal performance curve of field metabolism in a wild fish. We investigate the thermal sensitivity of field metabolic rate in two sympatric, genetically distinct ecotypes of...

Data from: Plant traits of propagule banks and standing vegetation reveal flooding alleviates impacts of agriculture on wetland restoration

Samantha K. Dawson, David I. Warton, Richard T. Kingsford, Peter Berney, David A. Keith & Jane A. Catford
1. Restoration of degraded plant communities requires understanding of community assembly processes. Human land use can influence plant community assembly by altering environmental conditions and species’ dispersal patterns. Flooding, including from environmental flows, may counteract land use effects on wetland vegetation. We examined the influence of land use history and flood frequency on the functional composition of wetland plant communities along a regulated river. 2. We applied fourth corner modelling to determine species’ trait-based responses...

Data from: The genomes of two key bumblebee species with primitive eusocial organisation

Ben M. Sadd, Seth M. Barribeau, Guy Bloch, Dirk C. De Graaf, Peter Dearden, Christine Elsik, Jurgen Gadau, Cornelius Grimmelikhuijzen, Martin Hasselmann, Jeffrey Lozier, Hugh Robertson, Guy Smagghe, Eckart Stolle, Matthias Van Vaerenbergh, Robert Waterhouse, Erich Bornberg-Bauer, Steffan Klasberg, Anna Bennett, Francisco Camara, Roderic Guigo, Katharina Hoff, Marco Mariotti, Monica Munos-Torres, Terence Murphy, Didac Santesmasses … & Kim C. Worley
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects of bumblebee biology, including susceptibility to implicated population viability threats. Results: We report the high quality draft genome...

Data from: Historical and recent processes shaping the geographic range of a rocky intertidal gastropod: phylogeography, ecology, and habitat availability

Phillip B. Fenberg, Karine Posbic & Michael E. Hellberg
Factors shaping the geographic range of a species can be identified when phylogeographic patterns are combined with data on contemporary and historical geographic distribution, range-wide abundance, habitat/food availability, and through comparisons with codistributed taxa. Here, we evaluate range dynamism and phylogeography of the rocky intertidal gastropod Mexacanthina lugubris lugubris across its geographic range – the Pacific coast of the Baja peninsula and southern California. We sequenced mitochondrial DNA (CO1) from ten populations and compliment these...

Data from: Benefits and costs of ecological restoration: rapid assessment of changing ecosystem service values at a UK wetland

Francine M. R. Hughes, Kelvin S. H. Peh, Andrew Balmford, Rob H. Field, Anthony Lamb, Jennifer C. Birch, Richard B. Bradbury, Claire Brown, Stuart H. M. Butchart, Martin Lester, Ross Morrison, Isabel Sedgwick, Chris Soans, Alison J. Stattersfield, Peter A. Stroh, Ruth D. Swetnam, David H. L. Thomas, Matt Walpole, Stuart Warrington & Kelvin S.-H. Peh
Restoration of degraded land is recognized by the international community as an important way of enhancing both biodiversity and ecosystem services, but more information is needed about its costs and benefits. In Cambridgeshire, U.K., a long-term initiative to convert drained, intensively farmed arable land to a wetland habitat mosaic is driven by a desire both to prevent biodiversity loss from the nationally important Wicken Fen National Nature Reserve (Wicken Fen NNR) and to increase the...

Data from: Supporting local diversity of habitats and species on farmland: a comparison of three wildlife-friendly schemes

Chloe J. Hardman, Dominic P. G. Harrison, Pete J. Shaw, Tim D. Nevard, Brin Hughes, Simon G. Potts, Ken Norris & Dominic P.G. Harrison
Restoration and maintenance of habitat diversity have been suggested as conservation priorities in farmed landscapes, but how this should be achieved and at what scale are unclear. This study makes a novel comparison of the effectiveness of three wildlife-friendly farming schemes for supporting local habitat diversity and species richness on 12 farms in England. The schemes were: (i) Conservation Grade (Conservation Grade: a prescriptive, non-organic, biodiversity-focused scheme), (ii) organic agriculture and (iii) a baseline of...
