Data from: Predicting ground temperatures across European landscapes

Richard M. Gunton, Chiara Polce & William E. Kunin
1. Ambient temperatures in natural environments can vary widely over short distances, especially on rugged ground where exposure to solar radiation depends on slope and aspect. Temperatures can also fluctuate rapidly, reaching values not revealed by climate data. Such fine-scale variation raises challenges for modelling species distributions under changing climates. 2. To avoid misunderstanding current species distributions and future changes, temperatures must be modelled at high resolutions. Most existing methods either require extensive parameterisation or...

Data from: Organic farming enhances parasitoid diversity at the local and landscape scale

Diego J. Inclán, Pierfilippo Cerretti, Doreen Gabriel, Tim G. Benton, Steven M. Sait, William E. Kunin, Mark A. K. Gillespie & Lorenzo Marini
1. The magnitude of the benefits derived from organic farming within contrasting managed landscapes remains unclear and, in particular, the potential scale-dependent response of insect parasitoids is relatively unexplored. Identifying the scale at which parasitoids are affected by organic farming will be an important step to enhance their conservation. 2. We sampled tachinid parasitoids at the centre and margin of arable and grassland fields on paired organic and conventional farms located in landscapes with different...

Data from: A metagenetics approach to determine the diversity and distribution of cyst nematodes at the level of the country, the field and the individual

Sebastian Eves-Van Den Akker, Catherine Lilley, Alex Reid, Jon Pickup, Eric Anderson, Peter Cock, Mark Blaxter, Peter Urwin, John Jones, Vivian Blok, John T. Jones, Catherine J. Lilley, Peter E. Urwin, Vivian C. Blok & Peter J.A. Cock
Distinct populations of the potato cyst nematode (PCN) Globodera pallida exist in the UK that differ in their ability to overcome various sources of resistance. An efficient method for distinguishing between populations would enable pathogen-informed cultivar choice in the field. Science and Advice for Scottish Agriculture (SASA) annually undertake national DNA diagnostic tests to determine the presence of PCN in potato seed and ware land by extracting DNA from soil floats. These DNA samples provide...

Data from: Cellular hypertrophy and increased susceptibility to spontaneous calcium-release of rat left atrial myocytes due to elevated afterload

Haifei Zhang, Mark Cannell, Shang Jin Kim, Judy J. Watson, Ruth Norman, Sarah C. Calaghan, Clive J. Orchard, Andrew F. James, Mark B. Cannell & Clive H. Orchard
Atrial remodeling due to elevated arterial pressure predisposes the heart to atrial fibrillation (AF). Although abnormal sarcoplasmic reticulum (SR) function has been associated with AF, there is little information on the effects of elevated afterload on atrial Ca2+-handling. We investigated the effects of ascending aortic banding (AoB) on Ca2+-handling in rat isolated atrial myocytes in comparison to age-matched sham-operated animals (Sham). Myocytes were either labelled for ryanodine receptor (RyR) or loaded with fluo-3-AM and imaged...

Data from: Three dimensional tracking of a wide-ranging marine predator: flight heights and vulnerability to offshore wind farms

Ian R. Cleasby, Ewan D. Wakefield, Stuart Bearhop, Thomas W. Bodey, Stephen C. Votier & Keith C. Hamer
A large increase in offshore wind turbine capacity is anticipated within the next decade, raising concerns about possible adverse impacts on birds as a result of collision risk. Birds’ flight heights greatly influence this risk, yet height estimates are currently available only using methods such as radar- or ship-based observations over limited areas. Bird-borne data-loggers have the potential to provide improved estimates of collision risk and here, we used data from Global Position System (GPS)-loggers...

Flower density values of common British plant species [AgriLand]

M. Baude, W.E. Kunin & J. Memmott

Data from: Evolution and maintenance of haploid-diploid life cycles in natural populations: the case of the marine brown alga Ectocarpus

Lucía Couceiro, Mickael Le Gac, Heather M. Hunsperger, Stéphane Mauger, Christophe Destombe, J. Mark Cock, Sophia Ahmed, Susana M. Coelho, Myriam Valero & Akira F. Peters
The evolutionary stability of haploid-diploid life cycles is still controversial. Mathematical models indicate that niche differences between ploidy phases may be a necessary condition for the evolution and maintenance of these life cycles. Nevertheless, experimental support for this prediction remains elusive. In the present work, we explored this hypothesis in natural populations of the brown alga Ectocarpus. Consistent with the life cycle described in culture, E. crouaniorum in NW France and E. siliculosus in SW...

Data from: Genetic diversity, virulence and fitness evolution in an obligate fungal parasite of bees

Sophie. E. F. Evison, Kirsten Foley, Annette Bruun Jensen & William O. H. Hughes
Within-host competition is predicted to drive the evolution of virulence in parasites, but the precise outcomes of such interactions are often unpredictable due to many factors including the biology of the host and the parasite, stochastic events and co-evolutionary interactions. Here, we use a serial passage experiment (SPE) with three strains of a heterothallic fungal parasite (Ascosphaera apis) of the Honey bee (Apis mellifera) to assess how evolving under increasing competitive pressure affects parasite virulence...

Data from: Movements of genes between populations: are pollinators more effective at transferring their own or plant genetic markers?

Min Liu, Stephen G. Compton, Fo-En Peng, Jian Zhang, Xiao-Yong Chen, X.-Y. Chen & F.-E. Peng
The transfer of genes between populations is increasingly important in a world where pollinators are declining, plant and animal populations are increasingly fragmented and climate change is forcing shifts in distribution. The distances that pollen can be transported by small insects are impressive, as is the extensive gene flow between their own populations. We compared the relative ease by which small insects introduce genetic markers into their own and host-plant populations. Gene flow via seeds...

Data from: An experimental test of density-dependent selection on temperament traits of activity, boldness and sociability

Jean-François Le Galliard, Matthieu Paquet, Marianne Mugabo & J.-F. Le Galliard
Temperament traits are seen in many animal species, and recent evolutionary models predict that they could be maintained by heterogeneous selection. We tested this prediction by examining density-dependent selection in juvenile common lizards Zootoca viviparascored for activity, boldness and sociability at birth and at the age of 1 year. We measured three key life-history traits (juvenile survival, body growth rate and reproduction) and quantified selection in experimental populations at five density levels ranging from low...

Data from: The fossil record of ichthyosaurs, completeness metrics and sampling biases

Terri J. Cleary, Benjamin C. Moon, Alexander M. Dunhill & Michael J. Benton
Ichthyosaurs were highly successful marine reptiles with an abundant and well-studied fossil record. However, their occurrences through geological time and space are sporadic, and it is important to understand whether times of apparent species richness and rarity are real or the result of sampling bias. Here, we explore the skeletal completeness of 351 dated and identified ichthyosaur specimens, belonging to all 102 species, the first time that such a study has been carried out on...

Data from: Drug repurposing: a systematic approach to evaluate candidate oral neuroprotective interventions for secondary progressive multiple sclerosis

Hanna M. Vesterinen, Peter Connick, Cadi M. J. Irvine, Emily S. Sena, Kieren J. Egan, Gary G. Carmichael, Afiyah Tariq, Sue Pavitt, Jeremy Chattaway, Malcolm Robert Macleod, Siddharthan Chandran & Jeremy Chataway
Objective: To develop and implement an evidence based framework to select, from drugs already licenced, candidate oral neuroprotective drugs to be tested in secondary progressive multiple sclerosis. Design: Systematic review of clinical studies of oral putative neuroprotective therapies in MS and four other neurodegenerative diseases with shared pathological features, followed by systematic review and meta-analyses of the in vivo experimental data for those interventions. We presented summary data to an international multi-disciplinary committee, which assessed...

Data from: How well can body size represent effects of the environment on demographic rates? Disentangling correlated explanatory variables

Mollie E. Brooks, Marianne Mugabo, Gwendolen M. Rogers, Timothy G. Benton, Arpat Ozgul & Gwendolen M. Rodgers
Demographic rates are shaped by the interaction of past and current environments that individuals in a population experience. Past environments shape individual states via selection and plasticity, and fitness-related traits (e.g. individual size) are commonly used in demographic analyses to represent the effect of past environments on demographic rates. We quantified how well the size of individuals captures the effects of a population's past and current environments on demographic rates in a well-studied experimental system...

Data from: Microform-scale variations in peatland permeability and their ecohydrological implications

Andy J. Baird, Alice M. Milner, Antony Blundell, Graeme T. Swindles & Paul J. Morris
1. The acrotelm-catotelm model of peatland hydrological and biogeochemical processes posits that the permeability of raised bogs is largely homogenous laterally but varies strongly with depth through the soil profile; uppermost peat layers are highly permeable while deeper layers are, effectively, impermeable. 2. We measured down-core changes in peat permeability, plant macrofossil assemblages, dry bulk density and degree of humification beneath two types of characteristic peatland microform – ridges and hollows – at a raised...
