Modelled potential carbon storage based on land cover and published carbon storage values in urban landscapes of the South Midlands

D.R. Grafius, R. Corstanje & J. A. Harris
This dataset shows potential carbon storage as modelled for the urban areas of Milton Keynes/Newport Pagnell, Bedford, and Luton/Dunstable, UK. The modelling approach used the ‘InVEST (Integrated Valuation of Ecosystem Services and Trade-offs) 3.1.0’ ecosystem service model suite, raster land cover maps at two spatial resolutions (5 m and 25 m) and published literature values for carbon storage by land cover. The resulting data are presented in the form of two ‘GeoTIFF’ raster map files...

Arbuscular mycorrhizal fungi diversity data from a grassland microcosm experiment [NERC Soil Biodiversity Programme]

D. Johnson, P.J. Vandenkoornhuyse, J.R. Leake, L. Gilbert, , J.P Grime, J.P.W. Young & D.J. Read
These arbuscular mycorrhizal (AM) fungi diversity data were collected in 2000 as part of an investigation in an unfertilized limestone grassland soil supporting different synthesized vascular plant assemblages that had developed for three years. The experimental treatments comprised: bare soil; monocultures of the non mycotrophic sedge Carex flacca; monocultures of the mycotrophic grass Festuca ovina; and a species-rich mixture of four forbs, four grasses and four sedges. The experiment was undertaken in microcosms, set up...

Data from: Accurately quantifying the shape of birds' eggs

John D. Biggins, Jamie E. Thompson & Tim R. Birkhead
Describing the range of avian egg shapes quantitatively has long been recognised as difficult. A variety of approaches has been adopted, some of which aim to capture the shape accurately and some to provide intelligible indices of shape. The objectives here are to show that a (four-parameter) method proposed by Preston (1953) is the best option for quantifying egg shape, to provide and document an R program for applying this method to suitable photographs of...

Data from: Are assortative mating and genital divergence driven by reinforcement?

Johan Hollander, Mauricio Montaño-Rendón, Giuseppe Bianco, Xi Yang, Anja M. Westram, Ludovic Duvaux, David G. Reid & Roger K. Butlin
The evolution of assortative mating is a key part of the speciation process. Stronger assortment, or greater divergence in mating traits, between species pairs with overlapping ranges is commonly observed, but possible causes of this pattern of reproductive character displacement are difficult to distinguish. We use a multidisciplinary approach to provide a rare example where it is possible to distinguish among hypotheses concerning the evolution of reproductive character displacement. We build on an earlier comparative...

Data from: C4 savanna grasses fail to maintain assimilation in drying soil under low CO2 compared with C3 trees despite lower leaf water demand

Joe Quirk, Chandra Bellasio, David A. Johnson, Colin P. Osborne & David J. Beerling
1) C4 photosynthesis evolved when grasses migrated out of contracting forests under a declining atmospheric CO2 concentration ([CO2]a) and drying climate around 30 million years ago. C4 grasses are hypothesised to benefit from improved plant–water relations in open habitats like savannas, giving advantages over C3 plants under low [CO2]a. But experimental evidence in a low CO2 environment is limited and comparisons with C3 trees are needed to understand savanna vegetation patterns. 2) To test whether...

Data from: Genomic differentiation during speciation-with-gene-flow: comparing geographic and host-related variation in divergent life history adaptation in Rhagoletis pomonella

Meredith M. Doellman, Gregory J. Ragland, Glen R. Hood, Peter J. Meyers, Scott P. Egan, Thomas H.Q. Powell, Peter Lazorchak, Mary M. Glover, Cheyenne Tait, Hannes Schuler, Daniel A. Hahn, Stewart H. Berlocher, James J. Smith, Patrik Nosil, Jeffrey L. Feder, Daniel Hahn, Stewart Berlocher, Peter Meyers, Scott Egan, Jeffrey Feder, Glen Hood, Thomas Powell & Gregory Ragland
A major goal of evolutionary biology is to understand how variation within populations gets partitioned into differences between reproductively isolated species. Here, we examine the degree to which diapause life history timing, a critical adaptation promoting population divergence, explains geographic and host-related genetic variation in ancestral hawthorn and recently derived apple-infesting races of Rhagoletis pomonella. Our strategy involved combining experiments on two different aspects of diapause (initial diapause intensity and adult eclosion time) with a...

Data from: Low-smoke chulha in Indian slums: study protocol for a randomised controlled trial

Megha Thakur, Esther A. Boudewijns, Giridhara R. Babu, Bjorn Winkens, Luc P. De Witte, Jeroen Gruiskens, Preeti Sushama, Cristian T. Ghergu & Onno C. P. Van Schayck
Background: Biomass fuel is used as a primary cooking source by more than half of the world’s population, contributing to a high burden of disease. Although cleaner fuels are available, some households continue using solid fuels because of financial constraints and absence of infrastructure, especially in non-notified slums. The present study documents a randomised controlled study investigating the efficacy of improved cookstove on the personal exposure to air pollution and the respiratory health of women...

Data from: The pyriform egg of the Common Murre (Uria aalge) is more stable on sloping surfaces

Tim R. Birkhead, Jamie E. Thompson & Robert Montgomerie
The adaptive significance of avian egg shape is a long-standing problem in biology. For many years, it was widely believed that the pyriform shape of the Common Murre (Uria aalge) egg allowed it to either “spin like a top” or “roll in an arc,” thereby reducing its risk of rolling off the breeding ledge. There is no evidence in support of either mechanism. Two recent alternative hypotheses suggest that a pyriform egg confers mechanical strength...

Data from: Global pattern of nest predation is disrupted by climate change in shorebirds

Vojtěch Kubelka, Miroslav Šálek, Pavel Tomkovich, Zsolt Végvári, Robert P. Freckleton & Tamás Székely
Ongoing climate change is thought to disrupt trophic relationships, with consequences for complex interspecific interactions, yet the effects of climate change on species interactions are poorly understood, and such effects have not been documented at a global scale. Using a single database of 38,191 nests from 237 populations, we found that shorebirds have experienced a worldwide increase in nest predation over the past 70 years. Historically, there existed a latitudinal gradient in nest predation, with...

Data from: Dobzhansky-Muller incompatibilities, dominance drive, and sex-chromosome introgression at secondary contact zones: a simulation study

Luca Sciuchetti, Christophe Dufresnes, Elisa Cavoto, Alan Brelsford & Nicolas Perrin
Dobzhansky-Muller (DM) incompatibilities involving sex chromosomes have been proposed to account for Haldane’s rule (lowered fitness among hybrid offspring of the heterogametic sex) as well as Darwin’s corollary (asymmetric fitness costs with respect to the direction of the cross). We performed simulation studies of a hybrid zone to investigate the effects of different types of DM incompatibilities on cline widths and positions of sex-linked markers. From our simulations, X-Y incompatibilities generate steep clines for both...

Data from: A diet rich in C3 plants reveals the sensitivity of an alpine mammal to climate change

Sabuj Bhattacharyya, Deborah A. Dawson, Helen Hipperson & Farah Ishtiaq
Plant-herbivore interactions provide critical insights into the mechanisms that govern the spatiotemporal distributions of organisms. These interactions are crucial to understanding the impacts of climate change, which are likely to have an effect on the population dynamics of alpine herbivores. The Royle’s pika (Ochotona roylei, hereafter pika) is a lagomorph found in the western Himalaya, and is dependent on alpine plants that are at risk from climate change. As the main prey of many carnivores...

Data from: Large and fast human pyramidal neurons associate with intelligence

Natalia A Goriounova, Djai B Heyer, René Wilbers, Matthijs B Verhoog, Michele Giugliano, Christophe Verbist, Joshua Obermayer, Amber Kerkhofs, Harriët Smeding, Maaike Verberne, Sander Idema, Johannes C Baayen, Anton W Pieneman, Christiaan PJ De Kock, Martin Klein & Huibert D Mansvelder
It is generally assumed that human intelligence relies on efficient processing by neurons in our brain. Although gray matter thickness and activity of temporal and frontal cortical areas correlate with IQ scores, no direct evidence exists that links structural and physiological properties of neurons to human intelligence. Here, we find that high IQ scores and large temporal cortical thickness associate with larger, more complex dendrites of human pyramidal neurons. We show in silico that larger...

Data from: Stress‐induced secondary leaves of a boreal deciduous shrub (Vaccinium myrtillus) overwinter then regain activity the following growing season

Jarle W. Bjerke, Grzegorz Wierzbinski, Hans Tømmervik, Gareth K. Phoenix & Stef Bokhorst
The ericoid shrub Vaccinium myrtillus is one of several deciduous boreal plants that respond to larval defoliation by compensatory production of a new set of leaves within the same growing season soon after defoliation. This new set is termed as ‘secondary leaves’. The physiological performance and longevity of secondary leaves is poorly understood. Following a multi‐year larval outbreak in boreal Norway, we therefore monitored the fate of the secondary leaves from 2014 to 2016. We...

Data from: Ancient plants with ancient fungi: liverworts associate with early-diverging arbuscular mycorrhizal fungi

William R. Rimington, Silvia Pressel, Jeffrey G. Duckett, Katie J. Field, David J. Read & Martin I. Bidartondo
Arbuscular mycorrhizas are widespread in land plants including liverworts, some of the closest living relatives of the first plants to colonise land 500 MYA. Previous investigations reported near-exclusive colonisation of liverworts by the most recently evolved arbuscular mycorrhizal fungi, the Glomeraceae, indicating a recent acquisition from flowering plants at odds with the widely-held notion that arbuscular mycorrhizal-like associations in liverworts represent the ancestral symbiotic condition in land plants. We performed an analysis of symbiotic fungi...

Data from: Warming impacts on early life stages increase the vulnerability and delay the population recovery of a long-lived habitat-forming macroalga

Pol Capdevila, Bernat Hereu, Roberto Salguero-Gómez, Graciel·La Rovira, Alba Medrano, Emma Cebrian, Joaquim Garrabou, Diego K. Kersting & Cristina Linares
1. Understanding the combined effects of global and local stressors is crucial for conservation and management, yet challenging due to the different scales at which these stressors operate. Here we examine the effects of one of the most pervasive threats to marine biodiversity, ocean warming, on the early life stages of the habitat-forming macroalga Cystoseira zosteroides, its long-term consequences for population resilience and its combined effect with physical stressors. 2. First, we performed a controlled...

Data from: Inbreeding intensifies sex- and age-dependent disease in a wild mammal

Clare H. Benton, Richard J. Delahay, Freya A.P. Smith, Andrew Robertson, Robbie A. McDonald, Andrew J. Young, Terry A. Burke, Dave Hodgson & Freya A. P. Smith
1. The mutation accumulation theory of senescence predicts that age-related deterioration of fitness can be exaggerated when inbreeding causes homozygosity for deleterious alleles. A vital component of fitness, in natural populations, is the incidence and progression of disease. 2. Evidence is growing for natural links between inbreeding and ageing; between inbreeding and disease; between sex and ageing; and between sex and disease. However, there is scant evidence, to date, for links among age, disease, inbreeding...

Data from: Impact of urbanization on abundance and phenology of caterpillars and consequences for breeding in an insectivorous bird

Gábor Seress, Tamás Hammer, Veronika Bókony, Ernő Vincze, Bálint Preiszner, Ivett Pipoly, Csenge Sinkovics, Karl Evans, András Liker & Karl L. Evans
Urbanization can have marked effects on plant and animal populations’ phenology, population size, predator-prey interactions and reproductive success. These aspects are rarely studied simultaneously in a single system, and some are rarely investigated, e.g. how insect phenology responds to urban development. Here, we study a tri-trophic system of trees – phytophagous insects (caterpillars) – insectivorous birds (great tits) to assess how urbanization influences i) the phenology of each component of this system, ii) insect abundance...

Data from: Local and system-wide adaptation is influenced by population connectivity

Patrik Nosil, Victor Soria-Carrasco, Jeffery L. Feder, Samuel M. Flaxman, Zachariah Gompert, Jeffrey L. Feder & Zach Gompert
Complex systems can be conceptualized and studied as networks of nodes with varying connectivity between nodes. In well-connected systems, local disturbance of individual nodes can be countered by input from neighbouring nodes, buffering the system against local change. Thus, pronounced change in a well-connected system may not occur until the system hits a threshold or ‘tipping point’ that drives a shift to an alternative, system-wide state. In contrast, poorly connected systems are more prone to...

Data from: Riparian reserves help protect forest bird communities in oil palm dominated landscapes

Simon L. Mitchell, David P. Edwards, Henry Bernard, David Coomes, Tommaso Jucker, Zoe G. Davies & Matthew J. Struebig
1. Conversion of forest to oil palm agriculture is a significant and continuing threat to tropical biodiversity. Despite this, little is known about the value of riparian reserves in oil palm and how these conservation set-asides might best be managed to maintain biodiversity. 2. We characterised bird communities of 28 sites in an oil palm-forest mosaic in Sabah, Malaysia using 6104 encounters from 840 point counts. Sites included oil palm riparian reserves of various vegetation...

Data from: Genomic associations with bill length and disease reveal drift and selection across island bird populations

Claire Armstrong, David S. Richardson, Helen Hipperson, Gavin J. Horsburgh, Clemens Kuepper, Lawrence Percival-Alwyn, Matt Clark, Terry Burke & Lewis G. Spurgin
Island species provide excellent models for investigating how selection and drift operate in wild populations, and for determining how these processes act to influence local adaptation and speciation. Here, we examine the role of selection and drift in shaping genomic and phenotypic variation across recently separated populations of Berthelot's pipit (Anthus berthelotii), a passerine bird endemic to three archipelagos in the Atlantic. We first characterised genetic diversity and population structuring, which supported previous inferences of...

Data from: Natural selection and the predictability of evolution in Timema stick insects

Patrik Nosil, Romain Villoutreix, Clarissa F. De Carvalho, Tim E. Farkas, Victor Soria-Carrasco, Jeff L. Feder, Bernard J. Crespi & Zachariah Gompert
Predicting evolution remains difficult. We studied the evolution of cryptic body coloration and pattern in a stick insect using 25 years of field data, experiments, and genomics. We found that evolution is more difficult to predict when it involves a balance between multiple selective factors and uncertainty in environmental conditions than when it involves feedback loops that cause consistent back-and-forth fluctuations. Specifically, changes in color-morph frequencies are modestly predictable through time (r2 = 0.14) and...

Data from: A high density SNP chip for genotyping great tit (Parus major) populations and its application to studying the genetic architecture of exploration behaviour

Jun-Mo Kim, Anna W. Santure, Henry J. Barton, John L. Quinn, Eleanor F. Cole, Marcel E. Visser, Ben C. Sheldon, Martien A.M. Groenen, Kees Van Oers, Jon Slate & J.-M. Kim
High density SNP microarrays (‘SNP chips’) are a rapid, accurate and efficient method for genotyping several hundred thousand polymorphisms in large numbers of individuals. While SNP chips are routinely used in human genetics and in animal and plant breeding, they are less widely used in evolutionary and ecological research. In this paper we describe the development and application of a high density Affymetrix Axiom chip with around 500 000 SNPs, designed to perform genomics studies...

Data from: A trade-off between thickness and length in the zebra finch sperm mid-piece

Tania Mendonca, Timothy R. Birkhead, Ashley J. Cadby, Wolfgang Forstmeier, Nicola Hemmings & Tim R. Birkhead
The sperm mid-piece has traditionally been considered to be the engine that powers sperm. Larger mid-pieces have therefore been assumed to provide greater energetic capacity. However, in the zebra finch Taeniopygia guttata, a recent study showed a surprising negative relationship between mid-piece length and sperm energy content. Using a multidimensional approach to study mid-piece structure, we tested whether this unexpected relationship can be explained by a trade-off between mid-piece length and mid-piece thickness and/or cristae...

Data from: Multi-modal signal evolution in birds: re-examining a standard proxy for sexual selection

Christopher R. Cooney, Hannah E.A. MacGregor, Nathalie Seddon, Joseph A. Tobias & Hannah E. A. MacGregor
Sexual selection is proposed to be an important driver of speciation and phenotypic diversification in animal systems. However, previous phylogenetic tests have produced conflicting results, perhaps because they have focused on a single signalling modality (visual ornaments), whereas sexual selection may act on alternative signalling modalities (e.g. acoustic ornaments). Here we compile phenotypic data from 259 avian sister species pairs to assess the relationship between visible plumage dichromatism—a standard index of sexual selection in birds—and...
