Fish biomass and density data for 3 intensively studied Wessex chalkstream sites, England, UK

J.I. Jones, A. Arnold, J. Pretty, C. Duerdoth, J. Murphy, A. Hawczak, L. Scott, R. Lauridsen & W. Beaumont
Density and biomass of fish taxa from three chalkstreams in the Wessex chalk area: Nine Mile River, River Till and River Wylye. Data were collected on five occasions, between October 2012 and October 2013. The density of fish taxa at each of the three streams was estimated using benthic fish sampling and multi-pass electrofishing. The mean biomass of individuals of each taxon at each site on each occasion was then applied to the density estimates...

Data from: Protracted growth impedes the detection of sexual dimorphism in non-avian dinosaurs

David W. E. Hone & Jordan C. Mallon
Evidence for sexual dimorphism is extremely limited in the non-avian dinosaurs despite their high diversity and disparity, and despite the fact that dimorphism is very common in vertebrate lineages of all kinds. Using body-size data from both Alligator mississippiensis and Rhea americana, which phylogenetically bracket the dinosaurs, we demonstrate that even when there is strong dimorphism in a species, random sampling of populations of individuals characterized by sustained periods of growth (as in the alligator...

Data from: Trpc2 Pseudogenization dynamics in bats reveal ancestral vomeronasal signaling, then pervasive loss

Laurel R. Yohe, Ramatu Abubakar, Christina Giordano, Elizabeth Dumont, Karen Sears, Stephen J. Rossiter, Liliana M. Davalos & Karen E. Sears
Comparative methods are often used to infer loss or gain of complex phenotypes, but few studies take advantage of genes tightly linked with complex traits to test for shifts in the strength of selection. In mammals vomerolfaction detects chemical cues mediating many social and reproductive behaviors and is highly conserved, but all bats exhibit degraded vomeronasal structures with the exception of two families (Phyllostomidae and Miniopteridae). These families either regained vomerolfaction after ancestral loss, or...

Data from: Detecting elusive aspects of wildlife ecology using drones: new insights on the mating dynamics and operational sex ratios of sea turtles

Gail Schofield, Kostas A. Katselidis, Martin K. S. Lilley, Richard D. Reina & Graeme C. Hays
Offspring and breeding (operational) sex ratios (OSR) are a key component of demographic studies. While offspring sex ratios are often relatively easy to measure, measuring OSRs is often far more problematic. Yet highly skewed OSRs, and a lack of male-female encounters, may be an important extinction driver. Using loggerhead sea turtles (Caretta caretta) as a case study, we showed the utility of drones, i.e. unmanned aerial vehicles (UAVs) to distinguish adult males and females in...

Riparian vegetation structure data for three intensively studied Wessex chalkstream sites, England, UK

J. Redhead & J. Murphy
A measure of the extent and complexity of riprian vegetation upstream of chalkstream sites derived from Light Detection and Ranging (LiDAR) data for three chalkstream sites within the Wessex chalk area (River Till, River Wylye and Nine Mile River). For each site there is an estimate of the minimum, maximum, mean and standard deviation height of vegetation along the banks for a range of distances upstream from the sampling location. Information on the extent and...

Data from: Cross-modal recognition of familiar conspecifics in goats

Benjamin J. Pitcher, Elodie F. Briefer, Luigi Baciadonna & Alan G. McElligott
When identifying other individuals, animals may match current cues with stored information about that individual from the same sensory modality. Animals may also be able to combine current information with previously acquired information from other sensory modalities, indicating that they possess complex cognitive templates of individuals that are independent of modality. We investigated whether goats (Capra hircus) possess cross-modal representations (auditory–visual) of conspecifics. We presented subjects with recorded conspecific calls broadcast equidistant between two individuals,...

Data from: Reconstructing Asian faunal introductions to eastern Africa from multi-proxy biomolecular and archaeological datasets

Mary E. Prendergast, Michael Buckley, Alison Crowther, Heidi Eager, Laurent Frantz, Ophélie Lebrasseur, Rainer Hutterer, Ardern Hulme-Beaman, Wim Van Neer, Katerina Douka, Margaret-Ashley Veall, Eréndira M.

Horton, Stephanie Wynne-Jones, Jeffrey Fleisher, Chantal Radimilahy, Henry Wright … & Mark Horton
Human-mediated biological exchange has had global social and ecological impacts. In sub-Saharan Africa, several domestic and commensal animals were introduced from Asia in the pre-modern period; however, the timing and nature of these introductions remain contentious. One model supports introduction to the eastern African coast after the mid-first millennium CE, while another posits introduction dating back to 3000 BCE. These distinct scenarios have implications for understanding the emergence of long-distance maritime connectivity, and the ecological...

Data from: Genomics of introgression in the Chinese horseshoe bat (Rhinolophus sinicus) revealed by transcriptome sequencing

Xiuguang Mao, Georgia Tsagkogeorga, Sebastian E. Bailey & Stephen J. Rossiter
Recent genomic studies show that introgression can occur at a genome-wide scale among recently diverged lineages. However, introgression is difficult to distinguish from incomplete lineage sorting (ILS), and these processes are expected to occur together. Moreover, ncDNA introgression is less easily detected than mtDNA introgression, and as such its prevalence is less well understood. The Chinese horseshoe bat (Rhinolophus sinicus) occurs as three distinct forms on mainland China: the subspecies R. s. septentrionalis and two...

Temporal variation in temperature and light availability in the Hampshire Avon, United Kingdom [Macronutrient Cycling]

J.F. Murphy, A. Arnold, C.P. Duerdoth, A. Hawczak, O. Pacioglu, J.L Pretty & J. I. Jones
The dataset contains measurements of temperature (°C) and light availability (Lux) in rivers in the Hampshire Avon catchment (UK). Six rivers within sub-catchments of contrasting geology (clay, sand, chalk) were investigated. The stream sites monitored were chosen to reflect a gradient of base flow index. Data were obtained via direct, field-based measurements every 15 minutes from February 2013 to (max) December 2014 with sensors tethered to the bed of the river at each site.

Cover of Land Cover Map 2007 broad habitat classes in the upstream catchment of the 20 Wessex chalkstream sites, England, UK

J. Murphy & T. Oliver
The data consists of a matrix of 12 land cover classes by 20 stream sites with the area of each land cover class given in km2. The areal coverage (km2) of each of 12 land cover classes was recorded for each of 20 chalkstream catchments in southern England. The 20 discrete chalkstream catchments are distributed along the white chalk geology extending from Dorset in the south west, through Wiltshire, to Hampshire in the north east,...

Data from: Experimental priming of independent and interdependent activity does not affect culturally-variable psychological processes

Kesson Magid, Vera Sarkol & Alex Mesoudi
Cultural psychologists have shown that people from Western countries exhibit more independent self-construal and analytic (rule-based) cognition than people from East Asia, who exhibit more interdependent self-construal and holistic (relationship-based) cognition. One explanation for this cross-cultural variation is the ecocultural hypothesis, which links contemporary psychological differences to ancestral differences in subsistence and societal cohesion: Western thinking formed in response to solitary herding, which fostered independence, while East Asian thinking emerged in response to communal rice...

Data from: Diet tracing in ecology: method comparison and selection

Jens M. Nielsen, Elizabeth L. Clare, Brian Hayden, Michael T. Brett & Pavel Kratina
1. Determining diet is a key prerequisite for understanding species interactions, food web structure and ecological dynamics. In recent years, there has been considerable development in both the methodology and application of novel and more traditional dietary tracing methods, yet there is no comprehensive synthesis that systematically and quantitatively compares among the different approaches. 2. Here we conceptualize diet tracing in ecology, provide recommendations for method selection, and illustrate the advantages of method integration. We...

Data from: Life-history strategy determines constraints on immune function

Benjamin James Parker, Seth M. Barribeau, Alice M. Laughton, Lynn H. Griffin & Nicole M. Gerardo
1) Determining the factors governing investment in immunity is critical for understanding host-pathogen ecological and evolutionary dynamics. Studies often consider disease resistance in the context of life-history theory, with the expectation that investment in immunity will be optimized in anticipation of disease risk. Immunity, however, is constrained by context-dependent fitness costs. How the costs of immunity vary across life-history strategies has yet to be considered. 2) Pea aphids are typically unwinged but produce winged offspring...

Data from: The fire ant social chromosome supergene variant Sb shows low diversity but high divergence from SB

Rodrigo Pracana, Anurag Priyam, Ilya Levantis, Richard A. Nichols & Yannick Wurm
Variation in social behavior is common yet little is known about the genetic architectures underpinning its evolution. A rare exception is in the fire ant Solenopsis invicta: Alternative variants of a supergene region determine whether a colony will have exactly one or up to dozens of queens. The two variants of this region are carried by a pair of “social chromosomes”, SB and Sb, which resemble a pair of sex chromosomes. Recombination is suppressed between...

Data from: Dietary changes in predators and scavengers in a nocturnally illuminated riparian ecosystem

Alessandro Manfrin, David Lehmann, Roy H.A. Van Grunsven, Stefano Larsen, Jari Syväranta, Geraldene Wharton, Christian C. Voigt, Michael T. Monaghan, Franz Hölker & Roy H. A. Van Grunsven
Aquatic and terrestrial ecosystems are linked by fluxes of carbon and nutrients in riparian areas. Processes that alter these fluxes may therefore change the diet and composition of consumer communities. We used stable carbon isotope (δ13C) analyses to test whether the increased abundance of aquatic prey observed in another study led to a dietary shift in riparian consumers in areas illuminated by artificial light at night (ALAN). We measured the contribution of aquatic-derived carbon to...

Data from: An active-radio-frequency-identification system capable of identifying co-locations and social-structure: validation with a wild free-ranging animal

Stephen A. Ellwood, Chris Newman, Robert A. Montgomery, Vincenzo Nicosia, Christina D. Buesching, Andrew Markham, Cecilia Mascolo, Niki Trigoni, Bence Pasztor, Vladimir Dyo, Vito Latora, Sandra E. Baker & David W. Macdonald
Behavioural events that are important for understanding sociobiology and movement ecology are often rare, transient and localised, but can occur at spatially distant sites e.g. territorial incursions and co-locating individuals. Existing animal tracking technologies, capable of detecting such events, are limited by one or more of: battery life; data resolution; location accuracy; data security; ability to co-locate individuals both spatially and temporally. Technology that at least partly resolves these limitations would be advantageous. European badgers...

Data from: Psychosocial interventions for post-traumatic stress disorder in refugees and asylum seekers resettled in high-income countries: systematic review and meta-analysis

Michela Nosè, Francesca Ballette, Irene Bighelli, Giulia Turrini, Marianna Purgato, Wietse Tol, Stefan Priebe & Corrado Barbui
Treatment of post-traumatic stress disorder (PTSD) in refugees and asylum seekers resettled in high-income countries presents specific challenges. This systematic review examined the effectiveness of psychosocial interventions for this group. We searched the Cochrane Central Register of randomised trials, CINAHL, EMBASE, PILOTS, PsycINFO, PubMed and Web of Science up to July 2016. Studies included randomised and controlled clinical trials comparing psychosocial interventions with waiting list or treatment as usual in adult refugees and asylum seekers...

Data from: Mate choice in sticklebacks reveals that immunogenes can drive ecological speciation

Demetra Andreou, Christophe Eizaguirre, Thomas Boehm & Manfred Milinski
Adaptation to ecologically contrasting niches can lead to the formation of new species. Theoretically, this process of ecological speciation can be driven by pleiotropic “magic traits” that genetically link natural and sexual selection. To qualify as a true magic trait, the pleiotropic function of a gene must be reflected in biologically relevant mechanisms underlying both local adaptation and mate choice. The immune genes of the major histocompatibility complex (MHC) contribute to parasite resistance and also...

J. I. Jones, A. Arnold, C.P. Duerdoth, A Hawczak, J.F. Murphy, O. Pacioglu, J.L. Pretty, I. A. Sanders, W.R.C. Beaumont, R.B. Lauridsen & L. Scott
The dataset contains measurements of the annual average abundance, biomass and elemental composition (C, N, P) of consumers (fish and invertebrates) in six rivers within sub-catchments of the Hampshire Avon of contrasting geology (clay, sand, chalk).

Benthic organic matter biomass data for three intensively studied Wessex chalkstream sites, England, UK

C. Duerdoth, A. Arnold, J. Pretty, J. Murphy, A. Hawczak & J.I. Jones
Ash-free dry mass (AFDM) of three distinct size fractions of organic matter (>1cm, >1mm and > 0.025mm) collected in quantitative samples of the benthic substrate determined from up to 10 replicate samples at three chalkstream sites in the Wessex chalk area (Nine Mile River, River Till and River Wylye) on each sampling occasion. Data were collected on seven occasions on the Wylye and Nine Mile River and on five occasions on the Till, between October...

Data from: Experimental evidence that parasites drive eco-evolutionary feedbacks

Franziska S. Brunner, Jaime M. Anaya-Rojas, Blake Matthews & Christophe Eizaguirre
Host resistance to parasites is a rapidly evolving trait that can influence how hosts modify ecosystems. Eco-evolutionary feedbacks may develop if the ecosystem effects of host resistance influence selection on subsequent host generations. In a mesocosm experiment, using a recently diverged (<100 generations) pair of lake and stream three-spined sticklebacks, we tested how experimental exposure to a common fish parasite (Gyrodactylus spp.) affects interactions between hosts and their ecosystems in two environmental conditions (low and...
