Data from: Vestigial singing behaviour persists after the evolutionary loss of song in crickets

Will T. Schneider, Christian Rutz, Berthold Hedwig & Nathan W. Bailey
The evolutionary loss of sexual traits is widely predicted. Because sexual signals can arise from the coupling of specialised motor activity with morphological structures, disruption to a single component could lead to overall loss of function. Opportunities to observe this process and characterise any remaining signal components are rare, but could provide insight into the mechanisms, indirect costs, and evolutionary consequences of signal loss. We investigated the recent evolutionary loss of a long-range acoustic sexual...

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: Thrifty phenotype vs cold adaptation: trade-offs in upper limb proportions of Himalayan populations of Nepal

Stephanie Payne, Rajendra B.C. Kumar, Emma Pomeroy, Alison Macintosh, Jay Stock & Rajendra Kumar BC
The multi-stress environment of high altitude has been associated with growth deficits in humans, particularly in zeugopod elements (forearm, lower leg). This is consistent with the thrifty phenotype hypothesis, which has been observed in Andeans, but has yet to be tested in other high altitude populations. In Himalayan populations, other factors, such as cold stress, may shape limb proportions. The current study investigated whether relative upper limb proportions of Himalayan adults (n=254) differ between highland...

Data from: Opposing patterns of intraspecific and interspecific differentiation in sex chromosomes and autosomes

Peter A. Moran, Sonia Pascoal, Timothée Cezard, Judith E. Risse, Michael G. Ritchie & Nathan W. Bailey
Linking intraspecific and interspecific divergence is an important challenge in speciation research. X chromosomes are expected to evolve faster than autosomes and disproportionately contribute to reproductive barriers, and comparing genetic variation on X and autosomal markers within and between species can elucidate evolutionary processes that shape genome variation. We performed RADseq on a 16-population transect of two closely-related Australian cricket species, Teleogryllus commodus and T. oceanicus, covering allopatry and sympatry. This classic study system for...

Data from: Visual approach computation in feeding hoverflies

Malin Thyselius, Paloma T. Gonzalez-Bellido, Trevor J. Wardill & Karin Nordstrom
On warm sunny days female hoverflies are often observed feeding from a wide range of wild and cultivated flowers. In doing so, hoverflies serve a vital role as alternative pollinators, and suggested to be the most important after bees and bumblebees. Unless the flower hoverflies are feeding from is large, they do not readily share the space with other insects, but instead opt to leave. We have used high-speed videography followed by 3D reconstruction of...

Data from: Back and forth Wolbachia transfers reveal efficient strains to control spotted wing drosophila populations

Julien Cattel, Katerina Nikolouli, Thibault Andrieux, Julien Martinez, Francis Jiggins, Sylvain Charlat, Fabrice Vavre, David Lejon, Patricia Gibert & Laurence Mouton
1.Since its recent invasion of the European and American continents, the spotted wing Drosophila Drosophila suzukii has become a burden of the fruit industry. Armed with a highly sclerotized ovipositor, females can lay eggs in a wider variety of ripening and healthy fruits than other Drosophila species. Economic losses due to Drosophila suzukii reach millions of dollars annually and methods to control natural populations in the field mainly rely on the use of chemical pesticides....

Data from: How maternal investment varies with environmental factors and the age and physiological state of wild tsetse Glossina pallidipes and Glossina morsitans morsitans

John W. Hargrove, M. Odwell Muzari & Sinead English
Theory suggests females should optimize resource allocation across reproductive bouts to maximize lifetime reproduction, balancing current and future reproductive efforts according to physiological state and projected survival and reproduction. Tests of these ideas focus on long-lived vertebrates: few measure age-related reproductive output in iteroparous invertebrates, or partition reserves between those allocated to offspring versus mothers. We investigated how maternal age, and environmental and physiological factors influence reproductive investment in wild tsetse, Glossina pallidipes Austen and...

Data from: Ecological conditions alter cooperative behaviour and its costs in a chemically defended sawfly

Carita Lindstedt, Antti Miettinen, Dalial Freitak, Tarmo Ketola, Andrés López-Sepulcre, Elina Mäntylä & Hannu Pakkanen
The evolution of cooperation and social behaviour is often studied in isolation from the ecology of organisms. Yet, the selective environment under which individuals evolve is much more complex in nature, consisting of ecological and abiotic interactions in addition to social ones. Here we measured the life-history costs of cooperative chemical defence in a gregarious social herbivore, Diprion pini pine sawfly larvae, and how these costs vary under different ecological conditions. We ran a rearing...

Data from: Weak population structure of the Spot-tail shark Carcharhinus sorrah and the Blacktip shark C. limbatus along the coasts of the Arabian Peninsula, Pakistan and South Africa

Dareen Almojil, Geremy Cliff, Julia L.Y. Spaet & Julia L. Y. Spaet
The increase in demand for shark meat and fins has placed shark populations worldwide under high fishing pressure. In the Arabian region, the Spot-tail shark Carcharhinus sorrah and the Blacktip shark Carcharhinus limbatus are among the most exploited species. In this study we investigated the population genetic structure of C. sorrah (n= 327) along the coasts of the Arabian Peninsula and of C. limbatus (n= 525) along the Arabian coasts, Pakistan and KwaZulu-Natal, South Africa...

Data from: Fossils reveal the complex evolutionary history of the mammalian regionalized spine

Katrina Elizabeth Jones, K. D. Angielczyk, P. D. Polly, J. J. Head, V. Fernandez, J. K. Lungmus, S. Tulga & S. E. Pierce
A unique characteristic of mammals is a vertebral column with anatomically distinct regions, but when and how this trait evolved remains unknown. Here we reconstruct vertebral regions and their morphological disparity in the extinct forerunners of mammals, the non-mammalian synapsids, to elucidate the evolution of mammalian axial differentiation. Mapping patterns of regionalization and disparity (heterogeneity) across amniotes reveals that both traits increased during synapsid evolution. However, the onset of regionalization predates increased heterogeneity. Based on...

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: Support for a clade of Placozoa and Cnidaria in genes with minimal compositional bias

Christopher E. Laumer, Harald Gruber-Vodicka, Michael G. Hadfield, Vicki B. Pearse, Ana Riesgo, John C. Marioni & Gonzalo Giribet
The phylogenetic placement of the morphologically simple placozoans is crucial to understanding the evolution of complex animal traits. Here, we examine the influence of adding new genomes from placozoans to a large dataset designed to study the deepest splits in the animal phylogeny. Using site-heterogeneous substitution models, we show that it is possible to obtain strong support, in both amino acid and reduced-alphabet matrices, for either a sister-group relationship between Cnidaria and Placozoa, or for...

Data from: Approaches to integrating genetic data into ecological networks

Elizabeth L. Clare, Aron J. Fazekas, Natalia V. Ivanova, Robin M. Floyd, Paul D.N. Hebert, Amanda M. Adams, Juliet Nagel, Rebecca Girton, Steven G. Newmaster, M. Brock Fenton & Paul D. N. Hebert
As molecular tools for assessing trophic interactions become common, research is increasingly focused on the construction of interaction networks. Here we demonstrate three key methods for incorporating DNA data into network ecology and discuss analytical considerations using a model consisting of plants, insects, bats and their parasites from the Costa Rican dry forest. The simplest method involves the use of Sanger sequencing to acquire long sequences to validate or refine field identifications, for example of...

Data from: A Tournaisian (earliest Carboniferous) conglomerate-preserved non-marine faunal assemblage and its environmental and sedimentological context

Jennifer A. Clack, Carys E. Bennett, Sarah J. Davies, Andrew C. Scott, Janet E. Sherwin & Timothy R. Smithson
A conglomerate bed from the Tournaisian Ballagan Formation of Scotland preserves a rich array of vertebrate and other non-marine fossils providing an insight into the wider ecosystem and palaeoenvironment that existed during this pivotal stage of Earth history. It challenges hypotheses of a long-lasting post-extinction trough following the end-Devonian extinction event. The fauna recovered includes a wide size range of tetrapods, rhizodonts and dipnoans, from tiny juveniles or small-bodied taxa up to large adults, and...

Data from: TAPBPR mediates peptide dissociation from MHC class I using a leucine lever

F. Tudor Ilca, Andreas Neerincx, Clemens Hermann, Ana Marcu, Stefan Stevanović, Janet E. Deane & Louise H. Boyle
Tapasin and TAPBPR are known to perform peptide editing on major histocompatibility complex class I (MHC I) molecules, however, the precise molecular mechanism(s) involved in this process remain largely enigmatic. Here, using immunopeptidomics in combination with novel cell-based assays that assess TAPBPR-mediate peptide exchange, we reveal a critical role for the K22-D35 loop of TAPBPR in mediating peptide exchange on MHC I. We identify a specific leucine within this loop that enables TAPBPR to facilitate...

Temperatures recorded 5cm above the forest floor in a gridded design (1 to 13m distance) within three, 1 hectare forest plots in Sabah, Borneo. The dataset also includes air temperature data from a nearby weather station at the same temporal resolution, and spatially-interpolated measurements of topography and canopy structure in each forest plot at a 1m resolution. iButton temperature measurement 5cm above the forest floor in gridded design (1-13m distance) within three 1-ha forest plots...

Drosophila C virus genomes, Cambridge (2017)

F.M. Jiggins & B. Longdon
The resource consists of genome sequence data for the Drosophila C virus that has been serially passaged through different species of Drosophila in the laboratory. The genomes were sequenced and aligned to the reference genome. The frequency of variants at both biallelic and triallelic sites was then calculated. We also generated a phylogeny of the species involved using published data. This data was generated to understand how viruses adapt to new host species by Francis...

Data from: Human variation in the shape of the birth canal is significant and geographically structured

Lia Betti & Andrea Manica
The human birth canal shows a tight fit with the size of the neonate, which can lead to obstetric complications. This is not the case in other apes, and has been explained as the outcome of conflicting evolutionary pressures for bipedal locomotion and parturition of a highly-encephalised fetus. Despite the suggested evolutionary constraints on the female pelvis, we show that women are, in fact, extremely variable in the shape of the bony birth canal, with...

Data from: Killer whales (Orcinus orca) in Iceland show weak genetic structure among diverse isotopic signatures and observed movement patterns

Sara B. Tavares, Filipa I.P. Samarra, Sonia Pascoal, Jeff A. Graves, Patrick J.O. Miller, Filipa I. P. Samarra & Patrick J. O. Miller
Local adaption through ecological niche specialization can lead to genetic structure between and within populations. In the Northeast Pacific, killer whales (Orcinus orca) of the same population have uniform specialized diets that are non-overlapping with other sympatric, genetically divergent and socially isolated killer whale ecotypes. However, killer whales in Iceland show intra-population variation of isotopic niches and observed movement patterns: some individuals appear to specialise on herring and follow it year-round while others feed upon...

Data from: Screening of candidate substrates and coupling ions of transporters by thermostability shift assays

Homa Majd, Martin S. King, Shane M. Palmer, Anthony C. Smith, Liam D. H. Elbourne, Ian T. Paulsen, David Sharples, Peter J. F. Henderson, Edmund R. S. Kunji, Peter JF Henderson, Liam DH Elbourne & Edmund RS Kunji
Substrates of most transport proteins have not been identified, limiting our understanding of their role in physiology and disease. Traditional identification methods use transport assays with radioactive compounds, but they are technically challenging and many compounds are unavailable in radioactive form or are prohibitively expensive, precluding large-scale trials. Here, we present a high-throughput screening method that can identify candidate substrates from libraries of unlabeled compounds. The assay is based on the principle that transport proteins...

Data from: Counting crows: flock structure and subgroup size variation in an urban population of crows

Florian Uhl, Max Ringler, Rachael Miller, Sarah A. Deventer, Thomas Bugnyar & Christine Schwab
Social complexity arises from the formation of social relationships like social bonds and dominance hierarchies. In turn, these aspects may be affected by the degree of fission-fusion dynamics, i.e. changes in group size and composition over time. Whilst fission-fusion dynamics has been studied in mammals, birds have received comparably little attention, despite some species having equally complex social lives. Here, we investigated the influence of environmental factors on aspects of fission-fusion dynamics in a free-ranging...

Data from: Y chromosome sequences reveal a short Beringian Standstill, rapid expansion, and early population structure of Native American founders

Thomaz Pinotti, Susana Revollo, Cézar Paz-Y-Miño, Ricardo Fujita, Fabrício Rodrigues Santos, Chris Tyler-Smith, Toomas Kivisild, Qasim Ayub, Anders Bergström, Yali Xue, Cinthia Cuellar, Dominique Ohasi, Daniela R. Lacerda, Marilza S. Jota, José E. Santos & Arne Solli
The Americas were the last inhabitable continents to be occupied by humans, with a growing multidisciplinary consensus for entry 15-25 thousand years ago (kya) from northeast Asia via the former Beringia land bridge. Autosomal DNA analyses have dated the separation of Native American ancestors from the Asian gene pool to 23 kya or later, and mtDNA analyses to ~25 kya, followed by isolation (‘Beringian Standstill’) for 2.4-9 ky and then a rapid expansion throughout the...

Data from: The early-life environment and individual plasticity in life history

Ornela De Gasperin, Ana Duarte, Sinead English, Alfredo Attisano & Rebecca M. Kilner
We tested whether the early-life environment can influence the extent of individual plasticity in a life history trait. We asked: can the early-life environment explain why, in response to the same adult environmental cue, some individuals invest more than others in current reproduction? And can it additionally explain why investment in current reproduction trades off against survival in some individuals, but is positively correlated with survival in others? We addressed these questions using the burying...

Data from: Anisotropic growth is achieved through the additive mechanical effect of material anisotropy and elastic asymmetry

Firas Bou Daher, Yuanjie Chen, Behruz Bozorg, Jack Clough, Henrik Jönsson & Siobhan A. Braybrook
Fast directional growth is a necessity for the young seedling; after germination, it needs to quickly penetrate the soil to begin its autotrophic life. In most dicot plants, this rapid escape is due to the anisotropic elongation of the hypocotyl, the columnar organ between the root and the shoot meristems. Anisotropic growth is common in plant organs and is canonically attributed to cell wall anisotropy produced by oriented cellulose fibers. Recently, a mechanism based on...

Data from: Moving from frugivory to seed dispersal: incorporating the functional outcomes of interactions in plant-frugivore networks

Benno I. Simmons, William J. Sutherland, Lynn V. Dicks, Jörg Albrecht, Nina Farwig, Daniel Garcia, Pedro Jordano & Juan P. González-Varo
1.There is growing interest in understanding the functional outcomes of species interactions in ecological networks. For many mutualistic networks, including pollination and seed dispersal networks, interactions are generally sampled by recording animal foraging visits to plants. However, these visits may not reflect actual pollination or seed dispersal events, despite these typically being the ecological processes of interest. 2.Frugivorous animals can act as seed dispersers, by swallowing entire fruits and dispersing their seeds, or as pulp...
