Data from: Exploring the mechanisms underlying a heterozygosity-fitness correlation for canine size in the Antarctic fur seal Arctocephalus gazella

Joseph I Hoffman, Jaume Forcada & William Amos
Although heterozygosity-fitness correlations (HFCs) are widely reported in the literature, most studies use too few markers to allow the proximate mechanisms to be convincingly resolved. Two competing hypotheses have been proposed: the general effects hypothesis, in which marker heterozygosity correlates with genome-wide heterozygosity and hence the inbreeding coefficient f, and the local effects hypothesis, in which one or more of the markers by chance exhibit associative overdominance. To explore the relative contributions of general and...

Data from: Biogeography of avian blood parasites (Leucocytozoon spp.) in two resident hosts across Europe: phylogeographic structuring or the abundance-occupancy relationship?

Tania Jenkins & Ian P. F. Owens
Relationships between hosts and parasites represent complex co-evolving systems that can vary both temporally and spatially. This variation may contribute to different co-evolutionary outcomes, ranging from highly geographically structured parasite populations comprised of specialist lineages that are locally abundant but have restricted global occupancy, to geographically unstructured parasite populations comprised of abundant generalists with broad global occupancy. Here, we present results from a large biogeographic study of the avian blood parasites of two sedentary host...

W. James Grecian, Matthew J. Witt, Martin J. Attrill, Stuart Bearhop, Peter H. Becker, Carsten Egevang, Robert W. Furness, Brendan J. Godley, Jacob González-Solís, David Grémillet, Matthias Kopp, Amélie Lescroël, Jason Matthiopoulos, Samantha C. Patrick, Hans-Ulrich Peter, Richard A. Phillips, Iain J. Stenhouse & Stephen C. Votier
Upwelling regions are highly productive habitats targeted by wide-ranging marine predators and industrial fisheries. In this study, we track the migratory movements of eight seabird species from across the Atlantic; quantify overlap with the Canary Current Large Marine Ecosystem (CCLME) and determine the habitat characteristics that drive this association. Our results indicate the CCLME is a biodiversity hotspot for migratory seabirds; all tracked species and more than 70% of individuals used this upwelling region. Relative...

LiDAR based Digital Terrain Model (DTM) data for South West England

F. Ferraccioli, F. Gerard, C. Robinson, T. Jordan, M. Biszczuk, L. Ireland, M. Beasley, A. Vidamour, A. Barker, R. Arnold, M. Dinn, A. Fox & A. Howard
This is a high resolution spatial dataset of Digital Terrain Model (DTM) data in South West England. The DTM along with a Digital Surface Model (DSM) cover an area of 9424 km2 that includes all the land west of Exmouth (i.e. west of circa 3 degrees 21 minutes West). The DTM represents the topographic model (height) of the bare earth. The dataset is a part of outcomes from the Centre for Ecology & Hydrology South...

Dissolved methane concentrations in groundwater

M.P. Wilson
This dataset contains dissolved methane concentrations from groundwater in Great Britain, predominantly from England. Data were collated in Microsoft Excel (.xlsx) format from four publicly accessible sources: the British Geological Survey (from Bell et al., 2017), the Environment Agency for England (from the online Water Quality Archive), and local baseline data for the shale gas sites of Preston New Road (from Cuadrilla Resources) and Kirby Misperton (from Third Energy). In total, 2997 dissolved methane concentrations...

Free energy calculations of noble-gas containing liquid iron and silicate melt

Y Li
Free energy calculations of noble-gas containing liquid iron and silicate melts at 50 GPa (3500 K) and 135 GPa (4200 K). The chemical potentials of noble gases can be obtained from these calculations. The Gibbs free energy of a series of iron and silicate melts with different concentrations of He were calculated. Then the chemical potentials of He can be derived from the concentration dependent Gibbs free energies. The chemical potentials of Ne, Ar, Kr...

Data from: Distorted views of biodiversity: spatial and temporal bias in species occurrence data

Elizabeth H. Boakes, Philip J. K. McGowan, Richard A. Fuller, Ding Chang-Qing, Natalie E. Clark, Kim O'Connor & Georgina M. Mace
Historical as well as current data on species distributions are needed to track changes in biodiversity. Species distribution data are found in a variety of sources but is likely that they include different biases towards certain time periods or places. By collating a large historical database of ~170,000 records of species in the avian order Galliformes dating back over two centuries and covering Europe and Asia, we investigate patterns of spatial and temporal bias in...

Data from: Lifespan and reproductive cost explain interspecific variation in the optimal onset of reproduction

Emeline Mourocq, Pierre Bize, Sandra Bouwhuis, Russell Bradley, Anne Charmantier, Carlos De La Cruz, Szymon Marian Obniak, Richard H. M. Espie, Márton Herenyi, Hermann Hötker, Oliver Kruger, John Marzluff, Anders P. Møller, Shinichi Nakagawa, Richard A. Phillips, Andrew N. Radford, Alexandre Roulin, János Török, Juliana Valencia, Martijn Van De Pol, Ian G. Warkentin, Isabel S. Winney, Andrew G. Wood, Michael Griesser & Szymon M. Drobniak
Fitness can be profoundly influenced by the age at first reproduction (AFR), but to date the AFR-fitness relationship only has been investigated intraspecifically. Here we investigated the relationship between AFR and average lifetime reproductive success (LRS) across 34 bird species. We assessed differences in the deviation of the Optimal AFR (i.e., the species-specific AFR associated with the highest LRS) from the age at sexual maturity, considering potential effects of life-history as well as social and...

Data from: A comprehensive large-scale assessment of fisheries bycatch risk to threatened seabird populations

Thomas A. Clay, Cleo Small, Geoffrey N. Tuck, Deborah Pardo, Ana P.B. Carneiro, Andrew G. Wood, John P. Croxall, Glenn T. Crossin & Richard A. Phillips
1. Incidental mortality (bycatch) in fisheries remains the greatest threat to many large marine vertebrates and is a major barrier to fisheries sustainability. Robust assessments of bycatch risk are crucial for informing effective mitigation strategies, but are hampered by missing information on the distributions of key life-history stages (adult breeders and non-breeders, immatures and juveniles). 2. Using a uniquely comprehensive biologging dataset (1697 tracks, 790 individuals), we assessed spatial overlap of four threatened seabird populations...

Exploring ecosystem markets for the delivery of public goods in the UK

Arjan Gosal, Helen Kendall, Gordon Mitchell, Mark Reed, Gordon Mitchell, Chris Rodgers & Guy Ziv
Environmental restoration and conservation challenges go beyond what can be financed publicly. There are significant opportunities for private investment in the delivery of public goods, benefitting both commercial organisations whose business relies on ecosystem services, as well as landowners, land managers and the general public. Thus, public-private financing of natural capital improvement presents an opportunity to increase the availability of funding for payments for ecosystem services that provide environmental and societal benefits. Though public-private partnerships...

Data from: Comparative population genomics reveals key barriers to dispersal in Southern Ocean penguins

Gemma V. Clucas, Jane L. Younger, Damian Kao, Louise Emmerson, Colin Southwell, Barbara Wienecke, Alex D. Rogers, Charles-Andre Bost, Gary D. Miller, Michael J. Polito, Patrick Lelliot, Jonathan Handley, Sarah Crofts, Richard A. Phillips, Michael J. Dunn, Karen J. Miller, Tom Hart & Patrick Lelliott
The mechanisms that determine patterns of species dispersal are important factors in the production and maintenance of biodiversity. Understanding these mechanisms helps to forecast the responses of species to environmental change. Here we used a comparative framework and genome-wide data obtained through RAD-seq to compare the patterns of connectivity among breeding colonies for five penguin species with shared ancestry, overlapping distributions, and differing ecological niches, allowing an examination of the intrinsic and extrinsic barriers governing...

Survey on mine-water geothermal in Poland

K Iwinska, K Maczka & A Lis
The study in three coal mining regions: Lower Silesia, Upper Silesia and Lublin (each N=500) was conducted using Computer Assisted Web Interview (CAWI). The questionnaire includes the block of questions concerning mine water awareness, climate change and local/place attachment. The survey online took 15 to 20 minutes and was prepared after in-depth pilot research among participants with different education level from the mining regions. We used the uninformed approach to the survey, so there were...

Data from: Global biogeographic patterns in bipolar moss species

Elisabeth Machteld Biersma, Jennifer A. Jackson, Jaakko Hyvonen, Satu Koskinen, Katrin Linse, Howard Griffiths & Peter Convey
A bipolar disjunction is an extreme, yet common, biogeographic pattern in non-vascular plants, yet its underlying mechanisms (vicariance or long-distance dispersal), origin and timing remain poorly understood. Here, combining a large-scale population dataset and multiple dating analyses, we examine the biogeography of four bipolar Polytrichales mosses, common to the Holarctic (temperate and polar Northern Hemisphere regions) and the Antarctic region (Antarctic, sub-Antarctic, southern South America) and other Southern Hemisphere (SH) regions. Our data reveal contrasting...

Data from: Influence of device accuracy and choice of algorithm for species distribution modelling of seabirds: a case study using black-browed albatrosses

Petra Quillfeldt, Jan O. Engler, Janet R. D. Silk, Richard A. Phillips & Janet R.D. Silk
Species distribution models (SDM) based on tracking data from different devices are used increasingly to explain and predict seabird distributions. However, different tracking methods provide different data resolutions, ranging from < 10m to >100km. To better understand the implications of this variation, we modeled the potential distribution of black-browed albatrosses Thalassarche melanophris from South Georgia that were simultaneously equipped with a Platform Terminal Transmitter (PTT) (high resolution) and a Global Location Sensor (GLS) logger (coarse...

Data from: Investigating trehalose synthesis genes after cold acclimation in the Antarctic nematode Panagrolaimus sp. DAW1

A.C. Seybold, David A. Wharton, Michael A.S. Thorne & Craig J. Marshall
Panagrolaimus sp. DAW1 is a freeze-tolerant Antarctic nematode which survives extensive intracellular ice formation. The molecular mechanisms of this extreme adaptation are still poorly understood. We recently showed that desiccation-enhanced RNA interference (RNAi) soaking can be used in conjunction with quantitative polymerase chain reaction (qPCR) to screen for phenotypes associated with reduced expression of candidate genes in Panagrolaimus sp. DAW1. Here, we present the use of this approach to investigate the role of trehalose synthesis...

Data from: Fur seal microbiota are shaped by the social and physical environment, show mother-offspring similarities and are associated with host genetic quality

Stefanie Grosser, Jan Sauer, Anneke Paijmans, Barbara Caspers, Jaume Forcada, Jochen Wolf & Joseph Hoffman
Despite an increasing appreciation of the importance of host-microbe interactions in ecological and evolutionary processes, the factors shaping microbial communities in wild populations remain poorly understood. We therefore exploited a natural experiment provided by two adjacent Antarctic fur seal (Arctocephalus gazella) colonies of high and low social density and combined 16S rRNA metabarcoding with microsatellite profiling of mother-offspring pairs to investigate environmental and genetic influences on skin microbial communities. Seal-associated bacterial communities differed profoundly between...

Data from: Migratory behavior of birds affects their coevolutionary relationship with blood parasites

Tania Jenkins, Gavin Huw Thomas, Olof Hellgren & Ian P. F. Owens
Host traits, such as migratory behavior, could facilitate the dispersal of disease causing parasites, potentially leading to the transfer of infections both across geographic areas and between host species. There is however, little quantitative information on whether variation in such host attributes do indeed affect the evolutionary outcome of host-parasite associations. Here, we employ Leucocytozoon blood parasites of birds, a group of parasites closely related to avian malaria, to study host-parasite coevolution in relation to...

Data from: The effect of a competitor on a model adaptive radiation

Quan-Guo Zhang, Richard Ellis & H. Charles J. Godfray
The ecological forces shaping adaptive radiations are of great interest to evolutionary ecologists. Here we experimentally test the hypothesis that the diversification of a lineage should be limited in the presence of competition from another taxon. We do this by studying a model microbial adaptive radiation (the generation of phenotypic diversity in asexual lineages of the bacterium Pseudomonas fluorescens) in the presence or absence of a competitor (Pseudomonas putida). In a spatially heterogeneous environment, the...

LiDAR based Digital Surface Model (DSM) data for South West England

F. Ferraccioli, F. Gerard, C. Robinson, T. Jordan, M. Biszczuk, L. Ireland, M. Beasley, A. Vidamour, A. Barker, R. Arnold, M. Dinn, A. Fox & A. Howard
This is a high resolution spatial dataset of Digital Surface Model (DSM) data in South West England. It is a part of outcomes from the CEH South West (SW) Project. There is also a Digital Terrain Model (DTM) dataset covering the same areas available from the SW project. Both DTM and DSM cover an area of 9424 km2 that includes all the land west of Exmouth (i.e. west of circa 3 degrees 21 minutes West)....
