Data from: The evolution of coexistence: reciprocal adaptation promotes the assembly of a simple community

Ronald D. Bassar, Troy Simon, William Roberts, Joseph Travis & David N. Reznick
Species coexistence may result by chance when co-occurring species do not strongly interact or it may be an evolutionary outcome of strongly interacting species adapting to each other. While patterns like character displacement indicate that coexistence has often been an evolutionary outcome, it is unclear how often the evolution of coexistence represents adaptation in only one species or reciprocal adaptation among all interacting species. Here we demonstrate a strong role for evolution in the coexistence...

Data from: The oldest actinopterygian highlights the cryptic early history of the hyperdiverse ray-finned fishes

Jing Lu, Sam Giles, Matt Friedman, Jan L. Den Blaauwen & Min Zhu
Osteichthyans comprise two divisions, each containing over 32,000 living species: Sarcopterygii (lobe-finned fishes and tetrapods) and Actinopterygii (ray-finned fishes). Recent discoveries from China highlight the morphological disparity of early sarcopterygians and extend their origin into the late Silurian. By contrast, the oldest unambiguous actinopterygians are roughly 30 million years younger, leaving a long temporal gap populated by fragments and rare body fossils of controversial phylogenetic placement. Here we reinvestigate the enigmatic osteichthyan Meemannia from the...

Data from: Telomere length reveals cumulative individual and transgenerational inbreeding effects in a passerine bird

Kat Bebbington, Lewis G. Spurgin, Eleanor A. Fairfield, Hannah L. Dugdale, Jan Komdeur, Terry Burke & David S. Richardson
Inbreeding results in more homozygous offspring that should suffer reduced fitness, but it can be difficult to quantify these costs for several reasons. First, inbreeding depression may vary with ecological or physiological stress and only be detectable over long time periods. Second, parental homozygosity may indirectly affect offspring fitness, thus confounding analyses that consider offspring homozygosity alone. Finally, measurement of inbreeding coefficients, survival and reproductive success may often be too crude to detect inbreeding costs...

Data from: Dynamics and biases of online attention: the case of aircraft crashes

Ruth García-Gavilanes, Milena Tsvetkova & Taha Yasseri
The Internet not only has changed the dynamics of our collective attention but also through the transactional log of online activities, provides us with the opportunity to study attention dynamics at scale. In this paper, we particularly study attention to aircraft incidents and accidents using Wikipedia transactional data in two different language editions, English and Spanish. We study both the editorial activities on and the viewership of the articles about airline crashes. We analyse how...

Data from: Misinformed leaders lose influence over pigeon flocks

Isobel Watts, Máté Nagy, Theresa Burt De Perera & Dora Biro
In animal groups where certain individuals have disproportionate influence over collective decisions, the whole group's performance may suffer if these individuals possess inaccurate information. Whether in such situations leaders can be replaced in their roles by better-informed group mates represents an important question in understanding the adaptive consequences of collective decision-making. Here, we use a clock-shifting procedure to predictably manipulate the directional error in navigational information possessed by established leaders within hierarchically structured flocks of...

Data from: The tale of the shrinking weapon: seasonal changes in nutrition affect weapon size and sexual dimorphism, but not contemporary evolution

Christine W. Miller, Grant C. McDonald & Allen J. Moore
Sexually selected traits are often highly variable in size within populations due to their close link with the physical condition of individuals. Nutrition has a large impact on physical condition, and thus, any seasonal changes in nutritional quality are predicted to alter the average size of sexually selected traits as well as the degree of sexual dimorphism in populations. However, although traits affected by mate choice are well studied, we have a surprising lack of...

Data from: Phylogenomic analysis of carangimorph fishes reveals flatfish asymmetry arose in a blink of the evolutionary eye

Richard C. Harrington, Brant C. Faircloth, Ron I. Eytan, W. Leo Smith, Thomas J. Near, Michael E. Alfaro & Matt Friedman
Background: Flatfish cranial asymmetry represents one of the most remarkable morphological innovations among vertebrates, and has fueled vigorous debate on the manner and rate at which strikingly divergent phenotypes evolve. A surprising result of many recent molecular phylogenetic studies is the lack of support for flatfish monophyly, where increasingly larger DNA datasets of up to 23 loci have yielded a polyphyletic or only weakly supported flatfish clade. Lack of resolution for flatfish relationships has been...

Data from: The outcome of competition between two parasitoid species is influenced by a facultative symbiont of their aphid host

Ailsa H. C. McLean & H. Charles J. Godfray
Symbiotic bacteria can act to protect their host against natural enemies. Where this protection is asymmetric against different natural enemies, protection conferred by symbionts has the potential to mediate interactions between natural enemies, as well as between enemies and the host. In pea aphids (Acyrthosiphon pisum), resistance against parasitoid wasps can be conferred by facultative symbiotic bacteria. We investigated whether the outcome of competition between two parasitoid species can be influenced by the presence of...

Data from: Multigenerational exposure to silver ions and silver nanoparticles reveals heightened sensitivity and epigenetic memory in Caenorhabditis elegans

Carolin L. Schultz, Anye Wamucho, Olga V. Tsyusko, Jason M. Unrine, Alison Crossley, Claus Svendsen & David J. Spurgeon
The effects from multigenerational exposures to engineered nanoparticles (ENPs) in their pristine and transformed states are currently unknown despite such exposures being an increasingly common scenario in natural environments. Here, we examine how exposure over 10 generations affects the sensitivity of the nematode Caenorhabditis elegans to pristine and sulfidized Ag ENPs and AgNO3. We also include populations that were initially exposed over six generations but kept unexposed for subsequent four generations to allow recovery from...

Data from: Co-infections and environmental conditions drive the distributions of blood parasites in wild birds

Nicholas J. Clark, Konstans Wells, Dimitar Dimitrov & Sonya M. Clegg
Experimental work increasingly suggests that non-random pathogen associations can affect the spread or severity of disease. Yet due to difficulties distinguishing and interpreting co-infections, evidence for the presence and directionality of pathogen co-occurrences in wildlife is rudimentary. We provide empirical evidence for pathogen co-occurrences by analysing infection matrices for avian malaria (Haemoproteus and Plasmodium spp.) and parasitic filarial nematodes (microfilariae) in wild birds (New Caledonian Zosterops spp.). Using visual and genus-specific molecular parasite screening, we...

Data on the movements of the seabird tick (Ixodes uriae) in an artificial arena

K.M. Wanelik, S. Wanless & M.A. Nunn
This dataset contains data on the movement of the seabird tick, Ixodes uriae, in an artificial arena. 24 adult female and 24 nymphal I. uriae were collected on the Isle of May, Scotland on the 25th-27th March 2014 and 18th July 2013 respectively. Nymphal ticks were taken from boiler suits worn by field workers, and adult female ticks were taken from cracks in the rock face. They were then transported to a laboratory where they...

Spatial attendance data for immature common guillemots (Uria aalge) at four sites in a large breeding colony

K.M. Wanelik, M.P. Harris & S. Wanless
This dataset contains data on the spatial attendance patterns of immature common guillemots (Uria aalge) at four sites in a large breeding colony. Data were collected from 25th April-12th May and 21st May-15th June 2013 at four sites on the Isle of May, Scotland. A grid was superimposed onto a photograph of each site. Grid cells were then classified as breeding or pre-breeding areas according to the presence or absence of breeding activity at any...

Plaque reduction neutralisation test results for common guillemot (Uria aalge) blood samples tested against twelve strains of a tick-borne virus, Great Island virus

K.M. Wanelik, M.P. Harris, S. Wanless & M.A. Nunn
This dataset contains plaque reduction neutralisation test (PRNT) results for common guillemot (Uria aalge) blood samples tested against twelve strains of a tick-borne virus, Great Island virus. 144 individual pre-breeding and breeding guillemots were captured between 1993 and 1995 on the Isle of May, Scotland and blood samples collected on filter paper. Plaque reduction neutralisation tests (PRNT) were then performed on these blood samples to detect virus strain-specific neutralising antibodies. Part of this dataset is...
