Data from: Characterization of stress coping style in Senegalese sole (Solea senegalensis) juveniles and breeders for aquaculture

Z. Ibarra-Zatarain, Elvira Fatsini, Sonia Rey, Olvido Chereguini, Ignacio Martin, Inmaculada Rasines, Carles Alcaraz & Neil Duncan
The aim of this work was to characterize stress coping styles of Senegalese sole (Solea senegalensis) juveniles and breeders and to select an operational behavioural screening test (OBST) that can be used by the aquaculture industry to classify and select between behavioural phenotypes in order to improve production indicators. A total of 61 juveniles and 59 breeders were subjected to five individual behavioural tests and two grouping tests. At the end of the individual tests,...

Data from: Sex as a strategy against rapidly evolving parasites

Stuart K. J. R. Auld, Shona K. Tinkler & Matthew C. Tinsley
Why is sex ubiquitous when asexual reproduction is much less costly? Sex disrupts coadapted gene complexes; it also causes costs associated with mate finding and the production of males who do not themselves bear offspring. Theory predicts parasites select for host sex, because genetically variable offspring can escape infection from parasites adapted to infect the previous generations. We examine this using a facultative sexual crustacean, Daphnia magna, and its sterilizing bacterial parasite, Pasteuria ramosa. We...

Data from: Subgenome dominance in an interspecific hybrid, synthetic allopolyploid, and a 140-year-old naturally established neo-allopolyploid monkeyflower

Patrick P. Edger, Ronald D. Smith, Michael R. McKain, Arielle M. Cooley, Mario Vallejo-Marin, Yao-Wu Yuan, Adam J. Bewick, Lexiang Ji, Adrian E. Platts, Megan J. Bowman, Kevin Childs, Jacob D. Washburn, Robert Schmitz, Gregory D. Smith, J. Chris Pires & Joshua R. Puzey
Recent studies have shown that one of the parental subgenomes in ancient polyploids is generally more dominant - having both retained more genes and being more highly expressed - a phenomenon termed subgenome dominance. The genomic features that determine how quickly and which subgenome dominates within a newly formed polyploid remain poorly understood. To investigate the rate of subgenome dominance emergence, we examined gene expression, gene methylation, and transposable element (TE) methylation in a natural,...

Data from: Global biogeography of mating system variation in seed plants

David A. Moeller, Ryan D. Briscoe Runquist, Annika M. Moe, Monica A. Geber, Carol Goodwillie, Pierre-Olivier Cheptou, Christopher G. Eckert, Elizabeth Elle, Mark O. Johnston, Susan Kalisz, Richard H. Ree, Risa D. Sargent, Mario Vallejo-Marin & Alice A. Winn
Latitudinal gradients in biotic interactions have been suggested as causes of global patterns of biodiversity and phenotypic variation. Plant biologists have long speculated that outcrossing mating systems are more common at low than high latitudes owing to a greater predictability of plant–pollinator interactions in the tropics; however, these ideas have not previously been tested. Here, we present the first global biogeographic analysis of plant mating systems based on 624 published studies from 492 taxa. We...

Data from: Strongly asymmetric hybridization barriers shape the origin of a new polyploid species and its hybrid ancestor

Mario Vallejo-Marin, Arielle M. Cooley, Michelle Yuequi Lee, Madison Folmer, Michael R. McKain & Joshua Robert Puzey
PREMISE OF THE STUDY: Hybridization between diploids and tetraploids can lead to new allopolyploid species, often via a triploid intermediate. Viable triploids are often produced asymmetrically, with greater success observed for “maternal-excess” crosses where the mother has a higher ploidy than the father. Here we investigated the evolutionary origins of Mimulus peregrinus, an allohexaploid recently derived from the triploid M. ×robertsii, to determine whether reproductive asymmetry has shaped the formation of this new species. METHODS:...

Data from: Evidence for selection-by-environment but not genotype-by-environment interactions for fitness-related traits in a wild mammal population

Adam Hayward, Josephine Pemberton, Camillo Berenos, Alastair J. Wilson, Jill G. Pilkington, Loeske E.B. Kruuk, Josephine M. Pemberton & Adam D. Hayward
How do environmental conditions influence selection and genetic variation in wild populations? There is widespread evidence for selection-by-environment interactions (S*E), but we reviewed studies of natural populations estimating the extent of genotype-by-environment interactions (G*E) in response to natural variation in environmental conditions, and found that evidence for G*E appears to be rare within single populations in the wild. Studies estimating the simultaneous impact of environmental variation on both selection and genetic variation are especially scarce....

Data from: Tree mortality across biomes is promoted by drought intensity, lower wood density and higher specific leaf area

Sarah Greenwood, Paloma Ruiz-Benito, Jordi Martínez-Vilalta, Francisco Lloret, Thomas Kitzberger, Craig D. Allen, Rod Fensham, Daniel C. Laughlin, Jens Kattge, Gerhard Bonisch, Nathan J. B. Kraft & Alistair S. Jump
Drought events are increasing globally, and reports of consequent forest mortality are widespread. However, due to a lack of a quantitative global synthesis, it is still not clear whether drought-induced mortality rates differ among global biomes and whether functional traits influence the risk of drought-induced mortality. To address these uncertainties, we performed a global meta-analysis of 58 studies of drought-induced forest mortality. Mortality rates were modelled as a function of drought, temperature, biomes, phylogenetic and...

Survey data of scientists on knowledge exchange in critical zone and geoscience

Y. Zheng, L.A Naylor, S. Waldron & D.M. Oliver
Survey data on knowledge exchange experience of both Chinese and British scientists working on critical zone and more broadly on geoscience. Data are drawn from questionnaire surveys to explore the knowledge management methods used in their environmental research. Data are anonymised social survey data from questionnaires. The data were generated during the NERC grant 'The transmissive critical zone: understanding the karst hydrology-biogeochemical interface for sustainable management' reference NE/N007425/1 undertaken as part of the NERC Using...

Data include the annual amount of KM publication in China and across the world, in WoS, the total amount of knowledge management (KM) publication during the searched years for each country (top 20), in Scopus, the total amount of KM publication during the searched years for each country (top 20), information about the retained KM publication for...

Spatial heterogeneity and habitat configuration overcome habitat composition influences on alpha and beta mammal diversity

André Luis Regolin, Milton Cezar Ribeiro, Felipe Martello, Geruza Leal Melo, Jonas Sponchiado, Luis Fernando De Castro Campanha, Larissa Sayuri Moreira Sugai, Thiago Sanna Freire Silva & Nilton Carlos Cáceres
The effects of habitat fragmentation on different taxa and ecosystems are subject to intense debate, and disentangling them is of utmost importance to support conservation and management strategies. We evaluated the importance of landscape composition and configuration, and spatial heterogeneity to explain α- and β-diversity of mammals across a gradient of percent woody cover and land use diversity. We expected species richness to be positively related to all predictive variables, with the strongest relationship with...

Tree diversity is key for promoting the diversity and abundance of forest‐associated taxa in Europe

Eric Allan, Evy Ampoorter, Luc Barbaro, Hervé Jactel, Lander Baeten, Johanna Boberg, Monique Carnol, Bastien Castagneyrol, Yohan Charbonnier, Seid Muhie Dawud, Marc Deconchat, Pallieter De Smedt, Hans De Wandeler, Virginie Guyot, Stephan Hättenschwiler, François‐Xavier Joly, Julia Koricheva, Harriet Milligan, Bart Muys, Diem Nguyen, Sophia Ratcliffe, Karsten Raulund‐Rasmussen, Michael Scherer‐Lorenzen, Fons Plas, J. Van Keer … & Lars Vesterdal
Plant diversity is an important driver of diversity at other trophic levels, suggesting that cascading extinctions could reduce overall biodiversity. Most evidence for positive effects of plant diversity comes from grasslands. Despite the fact that forests are hotspots of biodiversity, the importance of tree diversity, in particular its relative importance compared to other management related factors, in affecting forest‐associated taxa is not well known. To address this, we used data from 183 plots, located in...

Changes in tree community structures in defaunated forests are not driven only by dispersal limitation

Kirstie Hazelwood, C. E. Timothy Paine, Fernando H. Cornejo-Valverde, Elizabeth G. Pringle, Harald Beck & John Terborgh
1. Bushmeat hunting has reduced population sizes of large frugivorous vertebrates throughout the tropics, thereby reducing the dispersal of seeds. This is believed to affect tree population dynamics, and therefore community composition, because the seed dispersal of large-seeded trees depends upon large-bodied vertebrates. 2. We report on a long-running study of the effect of defaunation on a tropical tree community. In three censuses over 11 years, we compared sapling recruitment between a hunted and a...

Vegetation and habitat data for fragmented and continuous forest sites in Sabah, Malaysian Borneo, 2017

E.H. Waddell, S. Fleiss, B. Bala Ola, A. Bin Sailim, A. Jelling, K.L. Yeong, J. Tangah, S. Benedick, H. King, M. Hughes, C.J. McClean, D.S. Chapman, J.K. Hill & L.F. Banin
This dataset contains records for vegetation in 49 plots across 14 fragmented forest sites and 4 continuous forest sites in Sabah, Malaysian Borneo. Living vegetation and deadwood were surveyed in two or three 0.28-ha plots in each of the 18 sites. In addition to vegetation data, the dataset contains topsoil parameters, measurements of forest structure, and metrics of the degree of forest fragmentation in the landscape surrounding the plots. These data were collected in order...

Chernobyl-level radiation exposure damages bumblebee reproduction: a laboratory experiment

Katherine Raines, Penelope Whitehorn, David Copplestone & Matthew Tinsley
The consequences for wildlife of living in radiologically contaminated environments are uncertain. Previous laboratory studies suggest insects are relatively radiation-resistant; however, some field studies from the Chernobyl Exclusion Zone report severe adverse effects at substantially lower radiation dose rates than expected. Here we present the first laboratory investigation to study how environmentally-relevant radiation exposure affects bumblebee life-history, assessing the shape of the relationship between radiation exposure and fitness-loss. Dose rates comparable to the Chernobyl Exclusion...

Branching patterns in phylogenies cannot distinguish diversity-dependent diversification from time-dependent diversification

Theo Pannetier, César Martinez, Lynsey Bunnefeld & Rampal S. Etienne
One of the primary goals of macroevolutionary biology has been to explain general trends in long-term diversity patterns, including whether such patterns correspond to an up-scaling of processes occurring at lower scales. Reconstructed phylogenies often show decelerated lineage accumulation over time. This pattern has often been interpreted as the result of diversity-dependent diversification, where the accumulation of species causes diversification to decrease through niche filling. However, other processes can also produce such a slowdown, including...

Ecology directs host-parasite coevolutionary trajectories across Daphnia-microparasite populations

Stuart Auld & Sam Paplauskas
Host-parasite interactions often fuel coevolutionary change. However, parasitism is one of a myriad of possible ecological interactions in nature. Biotic (e.g., predation) and abiotic (e.g., temperature) variation can amplify or dilute parasitism as a selective force on hosts and parasites, driving population variation in (co)evolutionary trajectories. We dissected the relationships between wider ecology and coevolutionary trajectory using 16 ecologically complex Daphnia magna-Pasteuria ramosa ponds seeded with an identical starting host (Daphnia) and parasite (Pasteuria) population....

Policy labels and investment decision-making

Ian Lange, Mirko Moro & Mohammad Mahbubur Rahman
To combat winter mortality and morbidity in the United Kingdom (UK), the UK government developed the Winter Fuel Payment (WFP), which provides a lump sum payment to households whose oldest member is aged 60 or older. The WFP is an unconditional cash transfer, meaning it is given to all qualifying households regardless of income level and it is not mandated that WFP funds are to be spent on fuel.

Data from: Morphometric discrimination of two allozymically diagnosed sibling species of the Echinorhynchus gadi Zoega in Muller complex (Acanthocephala) in the North Sea.

Matthew T. Wayland, David I. Gibson & Christina Sommerville
Allozyme electrophoresis was used to detect biological species of the E. gadi complex from gadids from the northern North Sea. A fixed difference at one of nine enzyme loci surveyed confirmed the existence of two reproductively isolated, sympatric species. Mixed infections of two E. gadi spp. (termed A and B) were observed in Gadus morhua and Pollachius virens. E. gadi sp. B was also found in Melanogrammus aeglefinus and Merlangius merlangus. The presence of gravid...

Data from: Correlated evolution of mating system and floral display traits in flowering plants and its implications for the distribution of mating system variation

Carol Goodwillie, Risa D. Sargent, Susan Kalisz, Richard H. Ree, David A. Moeller, Mario Vallejo-Marin, Christopher G. Eckert, Alice A. Winn, Elizabeth Elle, Monica A. Geber & Mark O. Johnston
Reduced allocation to structures for pollinator attraction is predicted in selfing species. We explored the association between outcrossing and floral display in a broad sample of angiosperms. We used the demonstrated relationship to test for bias against selfing species in the outcrossing rate distribution, the shape of which has relevance for the stability of mixed mating. Relationships between outcrossing rate, flower size, flower number and floral display, measured as the product of flower size and...

Data from: Bergmann's body size rule operates in facultatively endothermic insects: evidence from a complex of cryptic bumblebee species

Jessica J. Scriven, Penelope R. Whitehorn, Dave Goulson & Matthew C. Tinsley
According to Bergmann’s rule we expect species with larger body size to inhabit locations with a cooler climate, where they may be well adapted to conserve heat and resist starvation. This rule is generally applied to endotherms. In contrast, body size in ectothermic invertebrates has been suggested to follow the reverse ecogeographic trend: these converse Bergmann’s patterns may be driven by the ecological constraints of shorter season length and lower food availability in cooler high...

Data from: Unravelling the evolutionary history and future prospects of endemic species restricted to former glacial refugia

Orly Razgour, Irene Salicini, Carlos Ibáñez, Ettore Randi & Javier Juste
The contemporary distribution and genetic composition of biodiversity bear a signature of species’ evolutionary histories and the effects of past climatic oscillations. For many European species, the Mediterranean peninsulas of Iberia, Italy and the Balkans acted as glacial refugia and the source of range recolonization, and as a result, they contain disproportionately high levels of diversity. As these areas are particularly threatened by future climate change, it is important to understand how past climatic changes...

Data from: Parasite transmission in a natural multihost-multiparasite community

Stuart K. Auld, Catherine L. Searle & Meghan A. Duffy
Understanding the transmission and dynamics of infectious diseases in natural communities requires understanding the extent to which the ecology, evolution and epidemiology of those diseases are shaped by alternative hosts. We performed laboratory experiments to test how parasite spillover affected traits associated with transmission in two co-occurring parasites: the bacterium Pasteuria ramosa and the fungus Metschnikowia bicuspidata. Both parasites were capable of transmission from the reservoir host (Daphnia dentifera) to the spillover host (Ceriodaphnia dubia),...

Data from: Fuels and fires influence vegetation via above- and below-ground pathways in a high-diversity plant community

Paul R. Gagnon, Heather A. Passmore, Matthew Slocum, Jonathan A. Myers, Kyle E. Harms, William J. Platt & C. E. Timothy Paine
1. Fire strongly influences plant populations and communities around the world, making it an important agent of plant evolution. Fire influences vegetation through multiple pathways, both above- and belowground. Few studies have yet attempted to tie these pathways together in a mechanistic way through soil heating even though the importance of soil heating for plants in fire-prone ecosystems is increasingly recognized. 2. Here we combine an experimental approach with structural equation modelling (SEM) to simultaneously...

Data from: A seascape genetic analysis reveals strong biogeographical structuring driven by contrasting processes in the polyploid saltmarsh species Puccinellia maritima and Triglochin maritima.

Romuald Rouger & Alistair S. Jump
Little is known about the processes shaping population structure in saltmarshes. It is expected that the sea should act as a powerful agent of dispersal. Yet, in contrast, import of external propagules into a saltmarsh is thought to be small. To determine the level of connectivity between saltmarsh ecosystems at a macro-geographical scale, we characterised and compared the population structure of two polyploid saltmarsh species, Puccinellia maritima and Triglochin maritima based on a seascape genetics...
