Hampshire Avon: Daily discharge, stage and water chemistry data from four tributaries (Sem, Nadder, West Avon, Ebble)

C. M. Heppell & A. Binley
This dataset contains discharge and surface water chemistry for the six river reaches of contrasting geology (clay, sand, chalk) in the Hampshire Avon. Manual measurements of discharge by the velocity-area method enabled construction of a stage-discharge relationship for each site. Stream stage was measured using pressure transducers from Summer 2013 to Summer 2015. River water samples were collected at 48-hr intervals from Summer 2013 to Summer 2014 and samples were analysed for selected solutes and...

Data from: Pupil dilation as an index of preferred mutual gaze duration

Nicola Binetti, Charlotte Harrison, Antoine Coutrot, Alan Johnston & Isabelle Mareschal
Most animals look at each other to signal threat or interest. In humans, this social interaction is usually punctuated with brief periods of mutual eye contact. Deviations from this pattern of gazing behaviour generally make us feel uncomfortable and are a defining characteristic of clinical conditions such as autism or schizophrenia, yet it is unclear what constitutes normal eye contact. Here, we measured, across a wide range of ages, cultures and personality types, the period...

Data from: Transcriptome profiling of immune tissues reveals habitat-specific gene expression between lake and river sticklebacks

Yun Huang, Frederic Chain, Mahesh Panchal, Christophe Eizaguirre, Martin Kalbe, Tobias Lenz, Irene Samonte, Monika Stoll, Erich Bornberg-Bauer, Thorsten B. Reusch, Manfred Milinski & Philine Feulner
The observation of habitat-specific phenotypes suggests the action of natural selection. The three-spined stickleback (Gasterosteus aculeatus) has repeatedly colonized and adapted to diverse freshwater habitats across the northern hemisphere since the last glaciation, while giving rise to recurring phenotypes associated with specific habitats. Parapatric lake and river populations of sticklebacks harbour distinct parasite communities, a factor proposed to contribute to adaptive differentiation between these ecotypes. However, little is known about the transcriptional response to the...

Data from: Maternal pathogen exposure causes diet- and pathogen-specific transgenerational costs

Joanne Littlefair, Alice Laughton, Rob Knell, Joanne E. Littlefair, Alice M. Laughton & Robert J. Knell
Transgenerational effects, whereby the environment experienced by a parent leads to an altered offspring phenotype, have now been described in a variety of taxa. In invertebrates, much of the research on these effects has concentrated on the role of parental exposure to pathogens or immune elicitors in determining offspring immune investment or disease resistance. To date, however, studies of transgenerational effects in invertebrates have generally been restricted to single infections or immune elicitors in ideal...

Data from: The association of feeding behavior with the resistance and tolerance to parasites in recently diverged sticklebacks

Jaime Mauricio Anaya-Rojas, Franziska S. Brunner, Nina Sommer, Ole Seehausen, Christophe Eizaguirre & Blake Matthews
Divergent natural selection regimes can contribute to adaptive population divergence, but can be sensitive to human-mediated environmental change. Nutrient loading of aquatic ecosystems, for example, might modify selection pressures by altering the abundance and distribution of resources and the prevalence and infectivity of parasites. Here, we used a mesocosm experiment to test for interactive effects of nutrient loading and parasitism on host condition and feeding ecology. Specifically, we investigated whether the common fish parasite Gyrodactylus...

Hampshire Avon: Vertical head gradient, saturated hydraulic conductivity and pore water chemistry data from six river reaches

C. M. Heppell & A. Binley
This dataset contains measurements of hydraulic head and saturated hydraulic conductivity together with porewater chemistry from banks and riverbed sediments in six river reaches of contrasting geology (clay, sand, chalk) in the Hampshire Avon. Falling and rising (slug) test data were used for computation of saturated hydraulic conductivity. Hydraulic head measurements were obtained from pressure transducers installed in piezometers between Summer 2013 and Summer 2015. Samples for porewater chemical analysis were collected from porewater sampling...

Data from: A tilt after-effect for images of buildings: evidence of selectivity for the orientation of everyday scenes

Ahamed Miflah Hussain Ismail, Joshua A. Solomon, Miles Hansard & Isabelle Mareschal
The tilt after-effect (TAE) is thought to be a manifestation of gain control in mechanisms selective for spatial orientation in visual stimuli. It has been demonstrated with luminance-defined stripes, contrast-defined stripes, orientation-defined stripes and even with natural images. Of course, all images can be decomposed into a sum of stripes, so it should not be surprising to find a TAE when adapting and test images contain stripes that differ by 15° or so. We show...

Data from: Dietary niche constriction when invaders meet natives: evidence from freshwater decapods

Michelle C. Jackson, Jonathan Grey, Katie Miller, J. Robert Britton & Ian Donohue
1. Invasive species are a key driver of global environmental change, with frequently strong negative consequences for native biodiversity and ecosystem processes. Understanding competitive interactions between invaders and functionally similar native species provides an important benchmark for predicting the consequences of invasion. However, even though having a broad dietary niche is widely considered a key factor determining invasion success, little is known about the effects of competition with functionally similar native competitors on the dietary...

Data from: Do agri-environment schemes result in improved water quality?

John Iwan Jones, John F. Murphy, Steven G. Anthony, Amanda Arnold, John H. Blackburn, Chas P. Duerdoth, Adrianna Hawczak, Greg O. Hughes, James L. Pretty, Peter D. Scarlett, Richard D. Gooday, Yusheng S. Zhang, Laura E. Fawcett, Diane Simpson, Anthony W. B. Turner, Pamela S. Naden, James Skates & Peter M. Scarlett
Improved water quality, through a reduction in diffuse pollution from agricultural sources, is an expected benefit of agri-environment schemes, but this has yet to be demonstrated in practice. Here, we evaluate the impact of Welsh agri-environment schemes on water quality and freshwater ecosystem condition through a combined monitoring and modelling framework. To determine the influence of the agri-environment schemes on ecosystem condition, spatially independent catchments dominated by a single scheme (>40% of catchment) were compared...

Riverine nitrogen gas production by anaerobic ammonium oxidation across contrasting geologies

K. Lansdown, C. M. Heppell & M. Trimmer
This dataset contains anaerobic ammonium oxidation (anammox) and denitrification activity of riverine sediments in the Hampshire Avon catchment (UK). Nine rivers within sub-catchments of contrasting geology (clay, sand, chalk) were investigated. Data were obtained via laboratory incubations (potential data) and direct, field-based measurements (in situ data) in summer 2013. Also included are chemical parameters determined in porewaters prior to in situ rate measurements.

Nitrogen transformations in riverine sediments, Hampshire Avon, United Kingdom

K. Lansdown, C. M. Heppell & M. Trimmer
The dataset contains denitrification, anaerobic ammonium oxidation (anammox) and nitrification activity of riverine sediments in the Hampshire Avon catchment (UK). Six rivers within sub-catchments of contrasting geology (clay, sand, chalk) were investigated. Data were obtained via direct, field-based measurements in seasonal campaigns conducted between spring 2013 and winter 2014. Also included are chemical parameters determined in porewaters prior to in situ rate measurements.

Data from: Is famine exposure during developmental life in rural Bangladesh associated with a metabolic and epigenetic signature in young adulthood? A historical cohort study

Sarah Finer, Mohd S. Iqbal, Rob Lowe, B.W. Ogunkolade, Sonia Pervin, Christopher Mathews, Melissa Smart, Dewan S. Alam & Graham A. Hitman
Objectives Famine exposure in utero can ‘programme’ an individual towards type 2 diabetes and obesity in later life. We sought to identify, (1) whether Bangladeshis exposed to famine during developmental life are programmed towards diabetes and obesity, (2) whether this programming was specific to gestational or postnatal exposure windows and (3) whether epigenetic differences were associated with famine exposure. Design A historical cohort study was performed as part of a wider cross-sectional survey. Exposure to...

Data from: Risk factors for admission at three urban emergency departments in England: a cross-sectional analysis of attendances over 1 month

Sharif A. Ismail, Ian Pope, Benjamin Bloom, Raquel Catalao, Emilie Green, Rebecca E. Longbottom, Gwyneth Jansen, David McCoy & Tim Harris

Design and setting: cross-sectional analysis of attendance data for patients from three urban EDs in England: a large teaching hospital and major trauma centre (Site 1), and two district general hospitals (Sites 2 and 3). Variables included: patient age, gender, ethnicity, deprivation score, arrival date and time, arrival by ambulance or otherwise, a variety of ED...

Data from: Copy-when-uncertain: bumblebees rely on social information when rewards are highly variable

Marco Smolla, Sylvain Alem, Lars Chittka & Susanne Shultz
To understand the relative benefits of social and personal information use in foraging decisions, we developed an agent-based model of social learning that predicts social information should be more adaptive where resources are highly variable and personal information where resources vary little. We tested our predictions with bumblebees and found that foragers relied more on social information when resources were variable than when they were not. We then investigated whether socially salient cues are used...

Data from: Unidirectional diploid–tetraploid introgression among British birch trees with shifting ranges shown by restriction site-associated markers

Jasmin Zohren, Nian Wang, Igor Kardailsky, James S. Borrell, Anika Joecker, Richard A. Nichols & Richard J. A. Buggs
Hybridization may lead to introgression of genes among species. Introgression may be bidirectional or unidirectional, depending on factors such as the demography of the hybridizing species, or the nature of reproductive barriers between them. Previous microsatellite studies suggested bidirectional introgression between diploid Betula nana (dwarf birch) and tetraploid B. pubescens (downy birch) and also between B. pubescens and diploid B. pendula (silver birch) in Britain. Here, we analyse introgression among these species using 51 237...

Data from: Goats display audience-dependent human-directed gazing behaviour in a problem-solving task

Christian Nawroth, Brett M. Jemma, Alan G. McElligott & Jemma M. Brett
Domestication is an important factor driving changes in animal cognition and behaviour. In particular, the capacity of dogs to communicate in a referential and intentional way with humans is considered a key outcome of how domestication as a companion animal shaped the canid brain. However, the lack of comparison with other domestic animals makes general conclusions about how domestication has affected these important cognitive features difficult. We investigated human-directed behaviour in an ‘unsolvable problem’ task...

Data from: Immunohistochemical typing of adenocarcinomas of the pancreatobiliary system improves diagnosis and prognostic stratification

Carlos Fernandez Moro, Alejandro Fernandez-Woodbridge, Melroy Alistair D'souza, Qianni Zhang, Benedek Bozoky, Senthil Vasan Kandaswamy, Piera Catalano, Rainer Heuche, Sonia Shtembari, Marco Del Chiaro, Olof Danielsson, Mikael Björnstedt, J. Matthias Löhr, Bengt Isaksson, Caroline Verbeke, Béla Bozóky & Rainer Heuchel
Background & Aims: Adenocarcinomas of the pancreatobiliary system are currently classified by their primary anatomical location. In particular, the pathological diagnosis of intrahepatic cholangiocarcinoma is still considered as a diagnosis of exclusion of metastatic adenocarcinoma. Periampullary cancers have been previously classified according to the histological type of differentiation (pancreatobiliary, intestinal), but overlapping morphological features hinder their differential diagnosis. We performed an integrative immunohistochemical analysis of pancreato-biliary tumors to improve their diagnosis and prediction of outcome....

Data from: Impact of controlled neonicotinoid exposure on bumblebees in a realistic field setting

Andres N. Arce, Thomas I. David, Emma L. Randall, Ana Ramos Rodrigues, Thomas J. Colgan, Yannick Wurm & Richard J. Gill
Pesticide exposure has been implicated as a contributor to insect pollinator declines. In social bees, which are crucial pollination service providers, the effect of low-level chronic exposure is typically non-lethal leading researchers to consider whether exposure induces sublethal effects on behaviour and whether such impairment can affect colony development. Studies under laboratory conditions can control levels of pesticide exposure and elucidate causative effects, but are often criticized for being unrealistic. In contrast, field studies can...
