Standardised site-level trends, mean productivity, and survival for migrant (arid and humid-zone) and resident species breeding across Europe

Catriona Morrison
Wildlife conservation policies directed at common and widespread, but declining, species are difficult to design and implement effectively, as multiple environmental changes are likely to contribute to population declines. Conservation actions ultimately aim to influence demographic rates, but targeting actions towards feasible improvements in these is challenging in widespread species with ranges that encompass a wide range of environmental conditions. Across Europe, sharp declines in the abundance of migratory landbirds have driven international calls for...

Life history, behavioural and morphometric data for queens and workers from an experiment manipulating costs of reproduction in bumble bee queens (Bombus terrestris)

D.H. Collins, D.C. Prince, J.L. Donelan, T. Chapman & A.F.G Bourke
Data on worker behaviour, experimental treatment and sampling, queen longevity, queen and colony fecundity and queen morphometrics collected for an experiment manipulating costs of reproduction in bumble bee queens (Bombus terrestris).

Family lineage and landscape quality data for wild bumblebee colonies across an agricultural landscape in Buckinghamshire, U.K.

C. Carvell, A.F.G. Bourke, S. Dreier, S.N. Freeman, S. Hulmes, W.C. Jordan, J.W. Redhead, J. Wang, S. Sumner & M.S. Heard
Family lineage relationships between spring queens, daughter workers and sister queens of three bumblebee species (Bombus terrestris, B. lapidarius and B. pascuorum) collected across the Hillesden Estate, Buckinghamshire, UK, between spring 2011 and spring 2012. A combination of land-use and habitat surveys, molecular genetics and spatial modelling was used to estimate the locations of wild colonies represented by greater than 1 worker and to calculate the proportions of cover represented by different habitat quality and...

Microsatellite genotype data for five species of bumblebee across an agricultural landscape in Buckinghamshire, UK

S. Dreier, J.W. Redhead, I. Warren, A.F.G. Bourke, M.S. Heard, W.C. Jordan, S. Sumner, J. Wang & C. Carvell
Microsatellite data for five species of common and declining bumblebee (Bombus terrestris, B. lapidarius, B. pascuorum, B. hortorum and B. ruderatus) collected across the Hillesden Estate, Buckinghamshire, UK, in summer 2011. Worker genotypes were determined from individuals sampled across an agricultural landscape and queen genotypes were reconstructed from sampled worker offspring. Data were collected as part of a project led by the Centre for Ecology & Hydrology, funded under the Insect Pollinators Initiative.

Eddy covariance flux measurements during Arctic cruises JR18006 and JR18007 in summer 2019

Thomas G Bell, Mingxi Yang & Yuanxu Dong
This is the high frequency (10 Hz) eddy covariance (EC) measurements which mainly contain the wind data, ship motion data, gas concentration data and the underway measurements. These data were measured on summer 2019 during two Arctic cruises JR18006 (from and to Aberdeen, UK and visited the Barents Sea ) and JR18007 (from Harwich, UK to Svalbard and visited the Greenland Sea). These EC data can be used to directly calculate the air-sea CO2 and...

Data from: Control of seminal fluid protein expression via regulatory hubs in D. melanogaster

Irina Mohorianu, Emily K. Fowler, Tamas Dalmay & Tracey Chapman
Highly precise, yet flexible and responsive co-ordination of expression across groups of genes underpins the integrity of many vital functions. However, our understanding of gene regulatory networks (GRNs) is often hampered by the lack of experimentally tractable systems, by significant computational challenges derived from the large number of genes involved or from difficulties in the accurate identification and characterization of gene interactions. Here we used a tractable experimental system in which to study GRNs: the...

Data from: Delayed dispersal and the costs and benefits of different routes to independent breeding in a cooperatively breeding bird

Sjouke A. Kingma, Kat Bebbington, Martijn Hammers, David S. Richardson & Jan Komdeur
Why sexually mature individuals stay in groups as nonreproductive subordinates is central to the evolution of sociality and cooperative breeding. To understand such delayed dispersal, its costs and benefits need to be compared with those of permanently leaving to float through the population. However, comprehensive comparisons, especially regarding differences in future breeding opportunities, are rare. Moreover, extraterritorial prospecting by philopatric individuals has generally been ignored, even though the factors underlying this route to independent breeding...

Data from: Oxidative status and fitness components in the Seychelles warbler

Janske Van De Crommenacker, Martijn Hammers, Jildou Van Der Woude, Marina Louter, Peter Santema, David S. Richardson & Jan Komdeur
Oxidative damage, caused by reactive oxygen species during aerobic respiration, is thought to be an important mediator of life-history trade-offs. To mitigate oxidative damage, antioxidant defence mechanisms are deployed, often at the cost of resource allocation to other body functions. Both reduced resource allocation to body functions and direct oxidative damage may decrease individual fitness, through reducing survival and/or reproductive output. The oxidative costs of reproduction have gained much attention recently, but few studies have...

Data from: Contribution of maternal effects to dietary selection in Mediterranean fruit flies.

Philip T. Leftwich, William J. Nash, Lucy A. Friend & Tracey Chapman
Individual responses to dietary variation represent a fundamental component of fitness, and nutritional adaptation can occur over just a few generations. Maternal effects can show marked proximate responses to nutrition, but whether they contribute to longer-term dietary adaptation is unclear. Here we tested the hypotheses that maternal effects: (i) contribute to dietary adaptation, (ii) diminish when dietary conditions are constant between generations, (iii) are trait-specific and (iv) interact with high- and low-quality food. We used...

Data from: The impact of translocations on neutral and functional genetic diversity within and among populations of the Seychelles warbler

David J. Wright, Lewis G. Spurgin, Nigel J. Collar, Jan Komdeur, Terry Burke & David S. Richardson
Translocations are an increasingly common tool in conservation. The maintenance of genetic diversity through translocation is critical for both the short and long term persistence of populations and species. However, the relative spatio-temporal impacts of translocations on neutral and functional genetic diversity and how this affects genetic structure among the conserved populations overall has received little investigation. We compared the impact of translocating different numbers of founders on both microsatellite and major histocompatibility complex (MHC)...

Data from: How quantitative is metabarcoding: a meta-analytical approach

Philip D. Lamb, Ewan Hunter, John K. Pinnegar, Simon Creer, Richard G. Davies & Martin I. Taylor
Metabarcoding has been used in a range of ecological applications such as taxonomic assignment, dietary analysis, and the analysis of environmental DNA. However, after a decade of use in these applications there is little consensus on the extent to which proportions of reads generated corresponds to the original proportions of species in a community. To quantify our current understanding we conducted a structured review and meta-analysis. The analysis suggests that a weak quantitative relationship may...

Data from: A further cost for the sicker sex? Evidence for male-biased parasite-induced vulnerability to predation

Jessica F. Stephenson, Cormac Kinsella, Joanne Cable & Cock Van Oosterhout
Males are typically the sicker sex. Data from multiple taxa indicate that they are more likely to be infected with parasites, and are less “tolerant,” or less able to mitigate the fitness costs of a given infection, than females. One cost of infection for many animals is an increased probability of being captured by a predator. A clear, hitherto untested, prediction is therefore that this parasite-induced vulnerability to predation is more pronounced among males than...

Data from: FlatNJ: a novel network-based approach to visualize evolutionary and biogeographical relationships

Monika Balvočūtė, Andreas Spillner & Vincent Moulton
Split networks are a type of phylogenetic network that allow visualization of conflict in evolutionary data. We present a new method for constructing such networks called FlatNetJoining (FlatNJ). A key feature of FlatNJ is that it produces networks that can be drawn in the plane in which labels may appear inside of the network. For complex data sets that involve, for example, non-neutral molecular markers, this can allow additional detail to be visualized as compared...

Data from: Evolution of ageing, costs of reproduction and the fecundity–longevity trade-off in eusocial insects

Pierre Blacher, Timothy J. Huggins, Andrew F.G. Bourke & Andrew F. G. Bourke
Eusocial insects provide special opportunities to elucidate the evolution of ageing as queens have apparently evaded costs of reproduction and reversed the fecundity-longevity trade-off generally observed in non-social organisms. But how reproduction affects longevity in eusocial insects has rarely been tested experimentally. In this study, we took advantage of the reproductive plasticity of workers to test the causal role of reproduction in determining longevity in eusocial insects. Using the eusocial bumblebee Bombus terrestris, we found...

Data from: Melanocortin 1 receptor (MC1R) gene sequence variation and melanism in the gray (Sciurus carolinensis), fox (Sciurus niger) and red (Sciurus vulgaris) squirrel

Helen R. McRobie, Linda M. King, Cristina Fanutti, Peter J. Coussons, Nancy D. Montcrief & Alison P. M. Thomas
Sequence variations in the melanocortin 1 receptor (MC1R) gene are associated with melanism in many different species of mammals, birds, and reptiles. The gray squirrel (Sciurus carolinensis), found in the British Isles, was introduced from North America in the late 19th century. Melanism in the British gray squirrel is associated with a 24-bp deletion in the MC1R. To investigate the origin of this mutation, we sequenced the MC1R of 95 individuals including 44 melanic gray...

Data from: Molecular characterisation of trophic ecology within an island radiation of insect herbivores (Curculionidae: Entiminae: Cratopus).

James J. N. Kitson, Ben H. Warren, F. B. Vincent Florens, Claudia Baider, Dominique Strasberg & Brent C. Emerson
The phytophagous beetle family Curculionidae is the most species-rich insect family known, with much of this diversity having been attributed to both co-evolution with food plants and host-shifts at key points within the early evolutionary history of the group. Less well understood is the extent to which patterns of host use vary within or among related species, largely because of the technical difficulties associated with quantifying this. Here we develop a recently characterised molecular approach...

Data from: Plasticity in growth of farmed and wild Atlantic salmon: is the increased growth rate of farmed salmon caused by evolutionary adaptations to the commercial diet?

Alison C. Harvey, Monica F. Solberg, Eva Troianou, Gary R. Carvalho, Martin I. Taylor, Simon Creer, Lise Dyrhovden, Ivar Helge Matre & Kevin A. Glover
Background: Domestication of Atlantic salmon for commercial aquaculture has resulted in farmed salmon displaying substantially higher growth rates than wild salmon under farming conditions. In contrast, growth differences between farmed and wild salmon are much smaller when compared in the wild. The mechanisms underlying this contrast between environments remain largely unknown. It is possible that farmed salmon have adapted to the high-energy pellets developed specifically for aquaculture, contributing to inflated growth differences when fed 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...

Data from: Landscape-scale variation in an anthropogenic factor shapes immune gene variation within a wild population

Catalina Gonzalez-Quevedo, Richard G. Davies, Karl P. Phillips, Lewis G. Spurgin, David S. Ricardson & David S. Richardson
Understanding the spatial scale at which selection acts upon adaptive genetic variation in natural populations is fundamental to our understanding of evolutionary ecology, and has important ramifications for conservation. The environmental factors to which individuals of a population are exposed can vary at fine spatial scales, potentially generating localized patterns of adaptation. Here, we compared patterns of neutral and major histocompatibility complex (MHC) variation within an island population of Berthelot's pipit (Anthus berthelotii) to assess...

Data from: Slow development as an evolutionary cost of long life

Martin I. Lind, Hwei-Yen Chen, Sara Meurling, Ana Cristina Guevara Gil, Hanne Carlsson, Martyna K. Zwoinska, Johan Andersson, Tuuli Larva & Alexei A. Maklakov
Life-history theory predicts a trade-off between early-life fitness and life span. While the focus traditionally has been on the fecundity-life span trade-off, there are strong reasons to expect trade-offs with growth rate and/or development time. We investigated the roles of growth rate and development time in the evolution of life span in two independent selection experiments in the outcrossing nematode Caenorhabditis remanei. First, we found that selection under heat-shock leads to the evolution of increased...

Data from: Age-dependent female responses to a male ejaculate signal alter demographic opportunities for selection

Claudia Fricke, Darrell Green, Walter E. Mills & Tracey Chapman
A central tenet of evolutionary explanations for ageing is that the strength of selection wanes with age. However, data on age-specific expression and benefits of sexually selected traits are lacking—particularly for traits subject to sexual conflict. We addressed this by using as a model the responses of Drosophila melanogaster females of different ages to receipt of sex peptide (SP), a seminal fluid protein transferred with sperm during mating. SP can mediate sexual conflict, benefitting males...

Data from: A combined field survey and molecular identification protocol for comparing forest arthropod biodiversity across spatial scales

Brent C. Emerson, Juliane Casquet, Heriberto López, Pedro Cardoso, Paulo A. V. Borges, Noémy Mollaret, Pedro Oromí, Dominique Strasberg & Christophe Thébaud
Obtaining fundamental biodiversity metrics such as alpha, beta and gamma diversity for arthropods is often complicated by a lack of prior taxonomic information and/or taxonomic expertise, which can result in unreliable morphologically based estimates. We provide a set of standardized ecological and molecular sampling protocols that can be employed by researchers whose taxonomic skills may be limited, and where there may be a lack of robust a priori information regarding the regional pool of species....

Data from: Experimental heatwaves compromise sperm function and cause transgenerational damage in a model insect

Kris Sales, Ramakrishnan Vasudeva, Matthew E. Dickinson, Joanne L. Godwin, Alyson J. Lumley, Lukasz Michalkzyk, Laura Hebberecht, Paul Thomas, Aldina Franco & Matthew J.G. Gage
Climate change is affecting biodiversity, but proximate drivers remain poorly understood. Here, we examine how experimental heatwaves impact on reproduction in an insect system. Male sensitivity to heat is recognised in endotherms, but ectotherms have received limited attention, despite comprising most of biodiversity and being more influenced by temperature variation. Using a flour beetle model system, we find that heatwave conditions (5 to 7 °C above optimum for 5 days) damaged male, but not female,...

Data from: Adaptive phenotypic response to climate enabled by epigenetics in a K-strategy species, the fish Leucoraja ocellata (Rajidae)

Jackie Lighten, Danny Incarnato, Ben J. Ward, Cock Van Oosterhout, Ian Bradbury, Mark Hanson & Paul Bentzen
The relative importance of genetic versus epigenetic changes in adaptive evolution is a hotly debated topic, with studies showing that some species appear to be able to adapt rapidly without significant genetic change. Epigenetic mechanisms may be particularly important for the evolutionary potential of species with long maturation times and low reproductive potential (‘K-strategists’), particularly when faced with rapidly changing environmental conditions. Here we study the transcriptome of two populations of the winter skate (Leucoraja...
