Land-use and climate change for 1.5 and 2.0 degrees centigrade warming scenarios (JULES land surface model)

A. Harper, T. Powell, P. Cox, E. Comyn-Platt & C. Huntingford
This dataset includes six sets of model output from JULES/IMOGEN simulations. Each set includes output from JULES (the Joint UK Land Environment Simulator) run with 34 climate change patterns from 2000-2099. The outputs provide carbon stocks and variables related to the surface energy budget to understand the implications of land-based climate mitigation.

Digital Surface Models for the South Saskatchewan River, Canada

P. Ashworth, A. Nicholas, D. Parsons & G. Sambrook Smith
Data were collected in 2015, 2016 and 2017 to provide Digital Surface Models (DSM) for two sections of the South Saskatchewan River, Canada. DSMs were generated using aerial plane images with a 0.06m ground resolution, captured at a height of c. 1500 m from a fixed-wing aeroplane with an UltraCamXp sensor. DSMs were generated as part of NERC project NE/L00738X/1. DSMs were constructed using imagery obtained on four occasions (13th May 2015; 2nd Sept 2016;...

Data from: Structure from motion photogrammetry: does the choice of software matter for Ecology?

Joel Forsmoo, Karen Anderson, Christopher Macleod, Mark Wilkinson, Leon DeBell & Richard Brazier
Structure-from-Motion (SfM) and Multiview-Stereo (MVS) is emerging as a flexible, self-service, remote sensing tool for generating fine-grained digital surface models (DSMs) in the Earth sciences and ecology. However, drone-based SfM+MVS applications have developed at a rapid pace over the past decade and there are now many software options available for data processing. Consequently, understanding of reproducibility issues caused by variations in software choice and their influence on data quality is relatively poorly understood. This understanding...

Data from: Sex-specific effects of fisheries and climate on the demography of sexually dimorphic seabirds

Dimas Gianuca, Stephen C. Votier, Deborah Pardo, Andrew G. Wood, Richard B. Sherley, Louise Ireland, Remi Choquet, Roger Pradel, Stuart Townley, Jaume Forcada, Geoffrey N. Tuck & Richard A. Phillips
1. Many animal taxa exhibit sex-specific variation in ecological traits, such as foraging and distribution. These differences could result in sex-specific responses to change, but such demographic effects are poorly understood. 2. Here we test for sex-specific differences in the demography of northern (NGP, Macronectes halli) and southern (SGP, M. giganteus) giant petrels - strongly sexually size-dimorphic birds that breed sympatrically at South Georgia, South Atlantic Ocean. Both species feed at sea or on carrion...

Towards a comparative approach to the structure of animal personality variation

Stephen White, David Pascall & Alastair Wilson
Latent personality traits underpinning observed behavioral variation have been studied in a great many species. However, a lack of standardized behavioral assays, coupled to a common reliance on inferring personality from a single, observed, behavioral trait makes it difficult to determine if, when, and how conclusions can be directly compared across taxa. Here, we estimate the among-individual (co)variance structure (ID) for a set of four behaviors expressed in an open field trial, putatively indicative of...

Data from: Knock-on community impacts of a novel vector: spillover of emerging DWV-B from Varroa-infested honeybees to wild bumblebees

Robyn Manley, Ben Temperton, Toby Doyle, Daisy Gates, Sophie Hedges, Michael Boots & Lena Wilfert
Novel transmission routes can directly impact the evolutionary ecology of infectious diseases, with potentially dramatic effect on host populations and knock-on effects on the wider host community. The invasion of Varroa destructor, an ectoparasitic viral vector in Western honeybees, provides a unique opportunity to examine how a novel vector affects disease epidemiology in a host community. This specialist honeybee mite vectors deformed wing virus (DWV), an important re-emerging honeybee pathogen that also infects wild bumblebees....

Evidence for individual discrimination and numerical assessment in collective antipredator behaviour in wild jackdaws (Corvus monedula)

Jenny R. Coomes, Guillam E. McIvor & Alex Thornton
Collective responses to threats occur throughout the animal kingdom but little is known about the cognitive processes underpinning them. Antipredator mobbing is one such response. Approaching a predator may be highly risky, but the individual risk declines and the likelihood of repelling the predator increases in larger mobbing groups. The ability to appraise the number of conspecifics involved in a mobbing event could therefore facilitate strategic decisions about whether to join. Mobs are commonly initiated...

Data from: Maasai pastoralists kill lions in retaliation for depredation of livestock by lions

Enoch M. Ontiri, Martin Odino, Antony Kasanga, Paula Kahumbu, Lance W. Robinson, Tom Currie & Dave J. Hodgson
The borders of national parks in Kenya are hotspots for human–wildlife conflict. The deliberate killing of lions by Maasai pastoralists is illegal, but continues despite mitigation attempts. Currently, there is a somewhat pervasive opinion, within the human–wildlife conflict literature, that lions are killed by Maasai people either as cultural ceremony or indiscriminately in response to the loss of livestock. We reconsider the indiscriminate reputation of lion‐killing, using a combination of structured dialogue and quantitative analysis....

Data from: Artificial selection on walking distance suggests a mobility-sperm competitiveness trade-off

Kentarou Matsumura, C. Ruth Archer, David J. Hosken & Takahisa Miyatake
Securing matings is a key determinant of fitness and in many species males are the sex that engages in mate searching. Searching for mates is often associated with increased mobility. This elevated investment in movement is predicted to trade-off with sperm competitiveness, but few studies have directly tested whether this trade-off occurs. Here, we assessed whether artificial selection on mobility affected sperm competitiveness and mating behavior, and if increased mobility was due to increased leg...

Data from: Local forage fish abundance influences foraging effort and offspring condition in an Endangered marine predator

Kate J. Campbell, Antje Steinfurth, Les G. Underhill, Janet C. Coetzee, Bruce M. Dyer, Katrin Ludynia, Azwianewi B. Makhado, Dagmar Merkle, Johan Rademan, Leshia Upfold & Richard B. Sherley
1. Understanding the functional relationship between marine predators and their prey is vital to inform ecosystem-based management. However, collecting concurrent data on predator behaviour and their prey at relevant scales is challenging. Moreover, opportunities to study these relationships in the absence of industrial fishing are extremely rare. 2. We took advantage of an experimental fisheries closure to study how local prey abundance influences foraging success and chick condition of Endangered African penguins Spheniscus demersus in...

Contrasting impacts of a novel specialist vector on multi-host viral pathogen epidemiology in wild and managed bees

Robyn Manley, Ben Temperton, Mike Boots & Wilfert Lena
Typically pathogens infect multiple host species. Such multi-host pathogens can show considerable variation in their degree of infection and transmission specificity, which has important implications for potential disease emergence. Transmission of multi-host pathogens can be driven by key host species and changes in such transmission networks can lead to disease emergence. We study two viruses that show contrasting patterns of prevalence and specificity in managed honeybees and wild bumblebees, black queen cell virus (BQCV) and...

Data from: Unscrambling variation in avian eggshell colour and patterning in a continent-wide study

Kiara L. L'Herpiniere, Louis G. O'Neill, Andrew F. Russell, Daisy E. Duursma & Simon C. Griffith
The evolutionary drivers underlying marked variation in the pigmentation of eggs within many avian species remains unclear. The leading hypotheses proposed to explain such variation advocate the roles of genetic differences, signalling and/or structural integrity. One means of testing amongst these hypotheses is to capitalise on museum collections of eggs obtained throughout a broad geographic range of a species to ensure sufficient variation in predictors pertaining to each hypothesis. Here we measured colouration and patterning...

Data from: Local interactions and their group-level consequences in flocking jackdaws

Hangjian Ling, Guillam E. McIvor, Kasper Van Der Vaart, Richard T. Vaughan, Alex Thornton & Nicholas T. Ouellette
As one of nature’s most striking examples of collective behaviour, bird flocks have attracted extensive research. However, we still lack an understanding of the attractive and repulsive forces that govern interactions between individuals within flocks and how these forces influence neighbours’ relative positions and ultimately determine the shape of flocks. We address these issues by analysing the three-dimensional movements of wild jackdaws (Corvus monedula) in flocks containing 2 to 338 individuals. We quantify the social...

Data from: Acid-base physiology over tidal periods in the mussel Mytilus edulis: size and temperature are more influential than seawater pH

Stephanie Mangan, Rod W. Wilson, Helen S. Findlay & Ceri Lewis
Ocean acidification (OA) studies to date have typically used stable open-ocean pH and CO2 values to predict the physiological responses of intertidal species to future climate scenarios, with few studies accounting for natural fluctuations of abiotic conditions or the alternating periods of emersion and immersion routinely experienced during tidal cycles. Here, we determine seawater carbonate chemistry and the corresponding in situ haemolymph acid-base responses over real time for two populations of mussel (Mytilus edulis) during...

Data from: The effect of bacterial mutation rate on the evolution of CRISPR-Cas adaptive immunity

Anne Chevallereau, Sean Meaden, Stineke Van Houte, Edze R. Westra & Clare Rollie
CRISPR-Cas immune systems are present in around half of bacterial genomes. Given the specificity and adaptability of this immune mechanism, it is perhaps surprising that they are not more widespread. Recent insights into the requirement for specific host factors for the function of some CRISPR-Cas subtypes, as well as the negative epistasis between CRISPR-Cas and other host genes, have shed light on potential reasons for the partial distribution of this immune strategy in bacteria. In...

Data from: Slower senescence in a wild insect population in years with a more female-biased sex ratio

Rolando Rodriguez-Munoz, Jelle Boonekamp, David Fisher, Paul Hopwood & Tom Tregenza
Life-history theories of senescence are based on the existence of a trade-off in resource allocation between body maintenance and reproduction. This putative trade-off means that environmental and demographic factors affecting the costs of reproduction should be associated with changes in patterns of senescence. In many species, competition among males is a major component of male reproductive investment, and hence variation in the sex ratio is expected to affect rates of senescence. We test this prediction...

Data from: Evaluating Bayesian stable isotope mixing models of wild animal diet and the effects of trophic discrimination factors and informative priors

George Swan, Stuart Bearhop, Steve Redpath, Matthew Silk, Cecily Goodwin, Richard Inger & Robbie McDonald
1. Ecologists quantify animal diets using direct and indirect methods, including analysis of faeces, pellets, prey items and gut contents. For stable isotope analyses of diet, Bayesian stable isotope mixing models (BSIMMs) are increasingly used to infer the relative importance of food sources to consumers. Although a powerful approach, it has been hard to test BSIMM performance for wild animals because precise, direct dietary data are difficult to collect. 2. We evaluated the performance of...

Data from: Morphological and physiological consequences of a dietary restriction during early life in bats

Magali Meniri, Doriane Hebinger, Mahaut Sorlin, Marine Ramirez, Emilie Kaufmann, Gaetan Glauser, Armelle Vallat, Nicolas Fasel & Fabrice Helfenstein
Early life adverse conditions can have major consequences on an individual’s life history traits. Oxidative stress has been hypothesized to be one main mechanism underlying the negative consequences of early life adverse conditions. To test this hypothesis, we restricted the food availability of Seba’s short-tailed bat (Carollia perspicillata) mothers of unweaned pups for 10 days, followed by ad libitum provisioning. We also had a control, unrestricted group. We explored the morphological consequences of dietary restriction...

Depth and velocity measurements in the South Saskatchewan River, Canada (2015-2017)

C. Unsworth, A. Nicholas, P. Ashworth, D. Parsons & G. Sambrook Smith
Data were collected in 2015, 2016 and 2017 to provide information on the distribution of flow depth and depth-averaged flow velocity at cross-sections on the South Saskatchewan River, Canada. Data were obtained using a Sontek M9 acoustic Doppler current profiler (aDcp) mounted onto either a small zodiac boat or a SonTek Hydroboard. Data for each cross-section is recorded in a single file. Individual points within each file represent single locations on the particular cross-section. Data...

Trade-off between reproduction and body maintenance in a wild field cricket (Gryllus campestris) population in North Spain (2006 to 2016)

R. Rodriguez-Munoz & T. Tregenza
Data comprise monitoring records of a population of Gryllus campestris, a flightless, univoltine field cricket that lives in and around burrows excavated among the grass in a meadow in Asturias (North Spain). The area has an altitude range from around 60 to 270 metres above sea level. The data present information on various mating-related activities of male crickets, including age, singing activity, dominance in fights, and lifespan. Data were collected from 2006 to 2016.

Shale anisotropy and natural hydraulic fracture propagation: An example from the Posidonienschiefer, Germany

J.N. Hooker, M. Ruhl, A.J. Dickson, L.N. Hanson, E. Idiz, S.P. Hesselbo & J. Cartwright
Cores recovered from the Posidonienschiefer (Posidonia Shale) in the Lower Saxony Basin, Germany, contain calcite filled fractures (veins) at low angle to bedding. The veins preferentially form where the shale is both organic rich and thermally mature, supporting previous interpretations that the veins formed as hydraulic fractures in response to volumetric expansion of organic material during catagenesis. Despite the presence of hydrocarbons during fracturing, the calcite fill is fibrous and so the veins appear to...

Future of the human climate niche

Chi Xu, Timothy Kohler, Timothy Lenton, Jens-Christian Svenning & Marten Scheffer
All species have an environmental niche, and despite technological advances, humans are unlikely to be an exception. Here, we demonstrate that for millennia, human populations have resided in the same narrow part of the climatic envelope available on the globe, characterized by a major mode around ∼11 °C to 15 °C mean annual temperature (MAT). Supporting the fundamental nature of this temperature niche, current production of crops and livestock is largely limited to the same...
