Data from: Explaining European fungal fruiting phenology with climate variability

Carrie Andrew, Einar Heegaard, Klaus Høiland, Beatrice Senn-Irlet, Thomas W. Kuyper, Irmgard Krisai-Greilhuber, Paul M. Kirk, Jacob Heilmann-Clausen, Alan C. Gange, Simon Egli, Claus Bässler, Ulf Büntgen, Lynne Boddy & Håvard Kauserud
Here we assess the impact of geographically dependent (latitude, longitude and altitude) changes in bioclimatic (temperature, precipitation and primary productivity) variability on fungal fruiting phenology across Europe. Two main nutritional guilds of fungi, saprotrophic and ectomycorrhizal, were further separated into spring and autumn fruiters. We used a path‐analysis to investigate how biogeographic patterns in fungal fruiting phenology coincided with seasonal changes in climate and primary production. Across central to northern Europe, mean fruiting varied by...

Data from: Disentangling synergistic disease dynamics: Implications for the viral biocontrol of rabbits

Konstans Wells, Damien A. Fordham, Barry W. Brook, Phillip Cassey, Tarnya Cox, Robert B. O’Hara, Nina I. Schwensow & Robert B. O'Hara
European rabbits (Oryctolagus cuniculus) have been exposed to rabbit haemorrhagic disease virus (RHDV) and myxoma virus (MYXV) in their native and invasive ranges for decades. Yet, the long‐term effects of these viruses on rabbit population dynamics remain poorly understood. In this context, we analysed 17 years of detailed capture–mark–recapture data (2000–2016) from Turretfield, South Australia, using a probabilistic state‐space hierarchical modelling framework to estimate rabbit survival and epidemiological dynamics. While RHDV infection and disease‐induced death...

Data from: Eradicating abundant invasive prey could cause unexpected and varied biodiversity outcomes: the importance of multi-species interactions

Miguel Lurgi, Euan G. Ritchie & Damien A. Fordham
1. Abundant and widely-distributed invasive prey can negatively affect co-occurring native species by competing for food and/or shelter, removing vegetation cover and reducing habitat complexity (changing predation risk), and by sustaining elevated abundances of invasive mesopredators. However, information regarding the community and trophic consequences of controlling invasive prey, and their temporal dynamics, remain poorly understood. 2. We used multi-species ecological network models to simulate the consequences of changing European rabbit Oryctolagus cuniculus abundance in an...

Data from: Camponotus floridanus ants incur a trade-off between phenotypic development and pathogen susceptibility from their mutualistic Endosymbiont Blochmannia

Veronica M. Sinotte, Samantha N. Freedman, Line V. Ugelvig, Marc A. Seid, Line Ugelvig, Samantha Freedman, Veronica Sinotte & Marc Seid
Various insects engage in microbial mutualisms in which the reciprocal benefits exceed the costs. Ants of the genus Camponotus benefit from nutrient supplementation by their mutualistic endosymbiotic bacteria, Blochmannia, but suffer a cost in tolerating and regulating the symbiont. This cost suggests that the ants face secondary consequences such as susceptibility to pathogenic infection and transmission. In order to elucidate the symbiont’s effects on development and disease defence, Blochmannia floridanus was reduced in colonies of...

Data from: Acid-sensing ion channels emerged over 600 MYA and are conserved throughout the deuterostomes

Timothy Lynagh, Yana Mikhaleva, Janne M. Colding, Joel C. Glover & Stephan A. Pless
Acid-sensing ion channels (ASICs) are proton-gated ion channels broadly expressed in the vertebrate nervous system, converting decreased extracellular pH into excitatory sodium current. ASICs were previously thought to be a vertebrate-specific branch of the DEG/ENaC family, a broadly conserved but functionally diverse family of channels. Here, we provide phylogenetic and experimental evidence that ASICs are conserved throughout deuterostome animals, showing that ASICs evolved over 600 million years ago. We also provide evidence of ASIC expression...

Data from: Naturalized plants decrease diet similarity between an invasive bird and its most similar native species

Gonçalo C. Rodrigues, Paulo Alves, Joana R. Vicente, João P. Honrado & Gonçalo C. Cardoso
Although invasive animals can compete with native species for resources, detrimental competition for food is seldom reported in the avian invasions literature. In temperate climates, food limitation and energetic stress are higher during winter and, thus, winter diets might reveal competition that is not apparent during the rest of the year. We compared autumn and winter diets of the invasive common waxbill (Estrilda astrild) in northwest Iberia, and of the native bird most similar to...

Data from: A mimicked bacterial infection prolongs stopover duration in songbirds – but more pronounced in short- than long-distance migrants

Arne Hegemann, Pablo Alcalde Abril, Sissel Sjöberg, Rachel Muheim, Thomas Alerstam, Jan-Åke Nilsson & Dennis Hasselquist
1) Migration usually consists of intermittent travel and stopovers, the latter being crucially important for individuals to recover and refuel to successfully complete migration. Quantifying how sickness behaviours influence stopovers is crucial for our understanding of migration ecology and how diseases spread. However, little is known about infections in songbirds, which constitute the majority of avian migrants. 2) We experimentally immune-challenged autumn migrating passerines (both short- and long-distance migrating species) with a simulated bacterial infection....

Data from: Population structure, relatedness and ploidy levels in an apple gene bank revealed through genotyping-by-sequencing

Bjarne Larsen, Kyle Gardner, Carsten Pedersen, Marian Ørgaard, Zoë Migicovsky, Sean Myles & Torben Bo Toldam-Andersen
In recent years, new genome-wide marker systems have provided highly informative alternatives to low density marker systems for evaluating plant populations. To date, most apple germplasm collections have been genotyped using low-density markers such as simple sequence repeats (SSRs), whereas only a few have been explored using high-density genome-wide marker information. We explored the genetic diversity of the Pometum gene bank collection (University of Copenhagen, Denmark) of 349 apple accessions using over 15,000 genome-wide single...

Data from: Trait evolution, resource specialization and vulnerability to plant extinctions among Antillean hummingbirds

Bo Dalsgaard, Jonathan D. Kennedy, Benno I. Simmons, Andrea C. Baquero, Ana M. Martín González, Allan Timmermann, Pietro K. Maruyama, Jimmy A. McGuire, Jeff Ollerton, William J. Sutherland & Carsten Rahbek
Species traits are thought to predict feeding specialisation and the vulnerability of a species to extinctions of interaction partners, but the context in which a species evolved and currently inhabits may also matter. Notably, the predictive power of traits may require that traits evolved to fit interaction partners. Furthermore, local abiotic and biotic conditions may be important. On islands, for instance, specialised and vulnerable species are predicted to be found mainly in mountains, whereas species...

Data from: Horizontal partner exchange does not preclude stable mutualism in fungus-growing ants

Jack Howe, Morten Schiøtt & Jacobus J. Boomsma
Vertical symbiont transmission tends to stabilize mutualisms by aligning the reproductive interests of cooperating species. The attine ants conform well to this principle, because all species are nutritionally dependent on vertically transmitted and clonally propagated fungal cultivars. Multiple mechanisms expressed by both partners constrain cultivar transmission between established colonies, but these appear not to preclude horizontal transfer during colony founding, consistent with multiple phylogenetic analyses indicating at least occasional horizontal transfer. The ecological and evolutionary...

Data from: Limited dietary overlap amongst resident Arctic herbivores in winter - complementary insights from complementary methods

Niels M. Schmidt, Jesper B. Mosbacher, Eero J. Vesterinen, Tomas Roslin & Anders Michelsen
Snow may prevent Arctic herbivores from accessing their forage in winter, forcing them to aggregate in the few patches with limited snow. In High Arctic Greenland, Arctic hare and rock ptarmigan often forage in muskox feeding craters. We therefore hypothesized that due to limited availability of forage, the dietary niches of these resident herbivores overlap considerably, and that the overlap increases as winter progresses. To test this, we analyzed fecal samples collected in early and...

Data from: The evolution of abdominal microbiomes in fungus-growing ants

Panagiotis Sapountzis, David R. Nash, Schiott Morten & Boomsma Jacobus
The attine ants are a monophyletic lineage that switched to fungus-farming ca. 55-60 MYA. They have become a model for the study of complex symbioses after additional fungal and bacterial symbionts were discovered, but their abdominal endosymbiotic bacteria remain largely unknown. Here we present a comparative microbiome analysis of endosymbiotic bacteria spanning the entire phylogenetic tree. We show that, across 17 representative sympatric species from eight genera sampled in Panama, abdominal microbiomes are dominated by...

Data from: Association of in utero persistent organic pollutant exposure with placental thyroid hormones

Zhong-Min Li, David Hernandez-Moreno, Katharina Maria Main, Niels Erik Skakkebæk, Hannu Kiviranta, Jorma Toppari, Ulla Feldt-Rasmussen, Heqing Shen, Karl-Werner Schramm & Meri De Angelis
In utero exposure to persistent organic pollutants (POPs) can result in thyroid function disorder, leading to concerns about their impact on fetal and neonatal development. The present study was performed to investigate the associations between placental levels of various POPs and thyroid hormones (THs). In a prospective Danish study initially established for assessing congenital cryptorchidism, 58 placenta samples were collected from mothers of boys born with (28) and without (30) cryptorchidism. The concentrations of polybrominated...

Charleen Gaunitz, Antoine Fages, Kristian Hanghøj, Anders Albrechtsen, Naveed Khan, Mikkel Schubert, Andaine Seguin-Orlando, Ivy J. Owens, Sabine Felkel, Olivier Bignon-Lau, Peter De Barros Damgaard, Alissa Mittnik, Azadeh F. Mohaseb, Hossein Davoudi, Saleh Alquraishi, Ahmed H. Alfarhan, Khaled A. S. Al-Rasheid, Eric Crubézy, Norbert Benecke, Sandra Olsen, Dorcas Brown, David Anthony, Ken Massy, Vladimir Pitulko, Aleksei Kasparov … & Ludovic Orlando
The Eneolithic Botai culture of the Central Asian steppes provides the earliest archaeological evidence for horse husbandry, ~5500 years ago, but the exact nature of early horse domestication remains controversial. We generated 42 ancient-horse genomes, including 20 from Botai. Compared to 46 published ancient- and modern-horse genomes, our data indicate that Przewalski’s horses are the feral descendants of horses herded at Botai and not truly wild horses. All domestic horses dated from ~4000 years ago...

Data from: Sex differences but no evidence of quantitative honesty in the warning signals of six-spot burnet moths (Zygaena filipendulae L.)

Emmanuelle Sophie Briolat, Mika Zagrobelny, Carl Erik Olsen, Jonathan D. Blount & Martin Stevens
The distinctive black and red wing pattern of six-spot burnet moths (Zygaena filipendulae, L.) is a classic example of aposematism, advertising their potent cyanide-based defences. While such warning signals provide a qualitatively honest signal of unprofitability, the evidence for quantitative honesty, whereby variation in visual traits could provide accurate estimates of individual toxicity, is more equivocal. Combining sophisticated measures of cyanogenic glucoside content and wing colour from the perspective of avian predators, we investigate the...

Data from: Environmental determinism, and not interspecific competition, drive morphological variability in Australasian warblers (Acanthizidae)

Vicente García-Navas, Marta Rodriguez-Rey, Petter Z. Marki & Les Christidis
Interspecific competition is thought to play a key role in determining the coexistence of closely related species within adaptive radiations. Competition for ecological resources can lead to different outcomes from character displacement to, ultimately, competitive exclusion. Accordingly, divergent natural selection should disfavor those species that are the most similar to their competitor in resource use, thereby increasing morphological disparity. Here we examined ecomorphological variability within an Australo-Papuan bird radiation, the Acanthizidae, which include both allopatric...

Data from: Barometer logging reveals new dimensions of individual songbird migration

Sissel Sjöberg, Lykke Pedersen, Gintaras Malmiga, Thomas Alerstam, Bengt Hansson, Dennis Hasselquist, Kasper Thorup, Anders P. Tøttrup, Arne Andersson & Johan Bäckman
Recent advances in tracking technology are based on the use of miniature sensors for recording new aspects of individual migratory behaviour. In this study, we have used activity data loggers with barometric and temperature sensors to record the flight altitudes as well as ground elevations during stationary periods of migratory songbirds. We tracked one individual of red-backed shrike and one great reed warbler along their autumn migration from Europe to Africa. Both individuals performed their...

Data from: Shortwave sand transport in the shallow surf zone

J. A. Brinkemper, T. Aagaard, A. T. M. De Bakker, B. G. Ruessink & J. A. Brinkkemper
Empirical parameterizations of the shortwave sand transport that are used in practical engineering models lack the representation of certain processes to accurately predict morphodynamics in shallow water. Therefore, measurements of near‐bed velocity and suspended sand concentration, collected during two field campaigns (at the Sand Engine and Ameland, the Netherlands) and one field‐scale laboratory experiment (BARDEXII), were here analyzed to study the magnitude and direction of the shortwave sand flux in the shallow surf zone. Shortwave...

Data from: Recurrent hybridisation events between Primula vulgaris, P. veris and P. elatior (Primulaceae, Ericales) challenge the species boundaries: Using molecular markers to re‐evaluate morphological identifications

Kira Tendal, Marian Ørgaard, Bjarne Larsen & Carsten Pedersen
Three Primula species, Primula vulgaris, P. veris and P. elatior, have been objects of fascination for gardeners and botanists over several centuries. The species are able to hybridise, and where they co-occur, hybrids are commonly found. In Denmark, Møns Klint on the island of Møn and Købelev Skov on Lolland are examples of localities where all three species occur and where the hybrids P. ×digenea, the hybrid between P. vulgaris and P. elatior, and P....

Data from: Territorial defence in a network: audiences only matter to male crabs primed for confrontation

Safi K. Darden, Maggie K. May, Natasha K. Boyland & Torben Dabelsteen
Territorial contests often occur in the presence of conspecifics not directly involved in the interaction. Actors may alter their behaviour in the presence of this audience, an ‘audience effect’, and audiences themselves may alter their behaviour as a result of observing an interaction, a ‘bystander effect’. Previous work has documented these effects by looking at each in isolation, but to our knowledge, none has investigated their interaction; something that is more likely to represent a...

Data from: No evidence of quantitative signal honesty across species of aposematic burnet moths (Lepidoptera: Zygaenidae)

Emmanuelle S. Briolat, Mika Zagrobelny, Carl E. Olsen, Jonathan D. Blount & Martin Stevens
Many defended species use conspicuous visual warning signals to deter potential predators from attacking. Traditional theory holds that these signals should converge on similar forms, yet variation in visual traits and the levels of defensive chemicals is common, both within and between species. It is currently unclear how the strength of signals and potency of defences might be related: conflicting theories suggest that aposematic signals should be quantitatively honest, or, in contrast, that investment in...

Data from: Vascular plant species richness and bioindication predict multi‐taxon species richness

Ane Kirstine Brunbjerg, Hans Henrik Bruun, Lars Dalby, Camilla Fløjgaard, Tobias Guldbjerg Frøslev, Toke Thomas Høye, Irina Goldberg, Thomas Læssøe, Morten D. D. Hansen, Lars Brøndum, Lars Skipper, Kåre Fog & Rasmus Ejrnæs
Plants regulate soils and microclimate, provide substrate for heterotrophic taxa, are easy to observe and identify and have a stable taxonomy, which strongly justifies their use as indicators in monitoring and conservation. However, there is no consensus as to whether plants are strong predictors of total multi‐taxon species richness. In this study, we investigate if general terrestrial species richness can be predicted by vascular plant richness and bioindication. To answer this question, we collected an...

Data from: Environment and host as large-scale controls of ectomycorrhizal fungi

Sietse Van Der Linde, Laura M. Suz, C. David L. Orme, Filipa Cox, Henning Andreae, Endla Asi, Bonnie Atkinson, Sue Benham, Christopher Carroll, Nathalie Cools, Bruno De Vos, Hans-Peter Dietrich, Johannes Eichhorn, Joachim Germann, Tine Grebenc, Hyun S. Gweon, Karin Hansen, Frank Jacob, Ferdinand Kristöfel, Pawel Lech, Miklos Manninger, Jan Martin, Henning Meesenburg, Päivi Merilä, Manuel Nicolas … & Martin I. Bidartondo
Explaining the large-scale diversity of soil organisms that drive biogeochemical processes—and their responses to environmental change—is critical. However, identifying consistent drivers of belowground diversity and abundance for some soil organisms at large spatial scales remains problematic. Here we investigate a major guild, the ectomycorrhizal fungi, across European forests at a spatial scale and resolution that is—to our knowledge—unprecedented, to explore key biotic and abiotic predictors of ectomycorrhizal diversity and to identify dominant responses and thresholds...

Data from: Latitudinal pattern of flowering synchrony in an invasive wind-pollinated plant

Shiyun Qiu, Xiao Xu, Shuangshuang Liu, Wenwen Liu, Jing Liu, Ming Nie, Fuchen Shi, Yihui Zhang, Jacob Weiner & Bo Li
Flowering synchrony can play an important role in plants’ reproductive success, which is essential for the successful establishment and spread of invasive plants. Although flowering synchrony has been found to be closely related to climatic factors, the effects of variation in such factors along latitudinal gradients on flowering synchrony, and the role of flowering synchrony in the reproductive success of invading populations remain largely unexplored. In a two-year field study, we examined the latitudinal variation...

Data from: Locality or habitat? Exploring predictors of biodiversity in Amazonia

Camila D. Ritter, Alexander Zizka, Christopher Barnes, R. Henrik Nilsson, Fabian Roger & Alexandre Antonelli
Amazonia is an environmentally heterogeneous and biologically megadiverse region, and its biodiversity varies considerably over space. However, existing knowledge on Amazonian biodiversity and its environmental determinants stems almost exclusively from studies of macroscopic above‐ground organisms, notably vertebrates and trees. In contrast, diversity patterns of most other organisms remain elusive, although some of them, for instance microorganisms, constitute the overwhelming majority of taxa in any given location, both in terms of diversity and abundance. Here, we...
