Data from: Extrapolating body masses in large terrestrial vertebrates

Nicolas E. Campione
Despite more than a century of interest, body-mass estimation in the fossil record remains contentious, particularly when estimating the body mass of taxa outside the size scope of living animals. One estimation approach uses humeral and femoral (stylopodial) circumferences collected from extant (living) terrestrial vertebrates to infer the body masses of extinct tetrapods through scaling models. When applied to very large extinct taxa, extant-based scaling approaches incur obvious methodological extrapolations leading some to suggest that...

Data from: Direct and pollinator-mediated effects of herbivory on strawberry and the potential for improved resistance

Anne Muola, Daniela Weber, Lisa E. Malm, Paul A. Egan, Robert Glinwood, Amy L. Parachnowitsch & Johan A. Stenberg
The global decline in pollinators has partly been blamed on pesticides, leading some to propose pesticide-free farming as an option to improve pollination. However, herbivores are likely to be more prevalent in pesticide-free environments, requiring knowledge of their effects on pollinators, and alternative crop protection strategies to mitigate any potential pollination reduction. Strawberry leaf beetles (SLB) Galerucella spp. are important strawberry pests in Northern Europe and Russia. Given that SLB attack both leaf and flower...

Data from: Mutations in COL1A1 and COL1A2 and dental aberrations in children and adolescents with osteogenesis imperfecta - a retrospective cohort study

Kristofer Andersson, Göran Dahllöf, Katarina Lindahl, Andreas Kindmark, Giedre Grigelioniene, Eva Åström & Barbro Malmgren
Osteogenesis imperfecta (OI) is a heterogeneous group of disorders of connective tissue, caused mainly by mutations in the collagen I genes (COL1A1 and COL1A2). Dentinogenesis imperfecta (DGI) and other dental aberrations are common features of OI. We investigated the association between collagen I mutations and DGI, taurodontism, and retention of permanent second molars in a retrospective cohort of 152 unrelated children and adolescents with OI. The clinical examination included radiographic evaluations. Teeth from 81 individuals...

Data from: A giant spurrey on a tiny island: on the phylogenetic position of Sanctambrosia manicata (Caryophyllaceae) and the generic circumscriptions of Spergula, Spergularia and Rhodalsine

Anneleen Kool & Mats Thulin
The only member of the generally herbaceous family Caryophyllaceae that may grow to a small tree is Sanctambrosia manicata, endemic to remote San Ambrosio Island, off the coast of Chile. The monospecific Sanctambrosia has been suggested to be closely related to Spergula and Spergularia (spurreys) on the basis of morphology, despite its treelike habit and gynodioecy. A plastid DNA dataset (ndhF, rps16, trnL-F) is used to investigate the relationships of Sanctambrosia and other members of...

Data from: Do brachiopods show substrate-related phenotypic variation? A case study from the Burgess Shale

Timothy P. Topper, Luke C. Strotz, Christian B. Skovsted & Lars E. Holmer
As sessile, benthic filter feeders, brachiopods share an intimate relationship with their chosen substrate. Individuals of Micromitra burgessensis in the Burgess Shale Formation are preserved in life position, attached to a range of hard substrates, including skeletal debris, conspecific brachiopods, sponges and enigmatic tubes. Here we investigate the phenotypic variability of M. burgessensis associated with differing substrate attachments. We apply geometric morphometrics to test for variation by plotting landmarks on the exterior of ventral and...

Data from: Two extended haplotype blocks are associated with adaptation to high altitude habitats in East African honey bees

Andreas Wallberg, Caspar Schöning, Matthew T. Webster & Martin Hasselmann
Understanding the genetic basis of adaption is a central task in biology. Populations of the honey bee Apis mellifera that inhabit the mountain forests of East Africa differ in behavior and morphology from those inhabiting the surrounding lowland savannahs, which likely reflects adaptation to these habitats. We performed whole genome sequencing on 39 samples of highland and lowland bees from two pairs of populations to determine their evolutionary affinities and identify the genetic basis of...

Data from: Reproductive trade-offs in a long-lived bird species: condition-dependent reproductive allocation maintains female survival and offspring quality

Michael Griesser, Gretchen F. Wagner, Szymon M. Drobniak & Jan Ekman
Life-history theory is an essential framework to understand the evolution of reproductive allocation. It predicts that individuals of long-lived species favour their own survival over current reproduction, leading individuals to refrain from reproducing under harsh conditions. Here we test this prediction in a long-lived bird species, the Siberian jay Perisoreus infaustus. Long-term data revealed that females rarely refrain from breeding, but lay smaller clutches in unfavourable years. Neither offspring body size, female survival nor offspring...

Data from: Natal dispersers pay a lifetime cost to increased reproductive effort in a wild bird population

Marion Germain, Tomas Pärt, Lars Gustafsson & Blandine Doligez
Natal dispersal is assumed to be costly. Such costs can be difficult to detect, and fitness consequences of dispersal are therefore poorly known. Because of lower phenotypic quality and/or familiarity with the environment, natal dispersers may be less buffered against a sudden increase in reproductive effort. Consequently, reproductive costs associated with natal dispersal may mostly be detected in harsh breeding conditions. We tested this prediction by comparing lifetime reproductive success between natal dispersers and non-dispersers...

Data from: Childhood adiposity and type 1 diabetes: a Mendelian randomization study

J. C. Censin, Christoph Nowak, Nicholas Cooper, Peter Bergsten, John A. Todd & Tove Fall
BACKGROUND: The incidence of type 1 diabetes (T1D) is increasing globally. One hypothesis is that increasing childhood obesity rates may explain part of this increase, but, as T1D is rare, intervention studies are challenging to perform. The aim of this study was to assess this hypothesis with a Mendelian randomization approach that uses genetic variants as instrumental variables to test for causal associations. METHODS AND FINDINGS: We created a genetic instrument of 23 single nucleotide...

Data from: The combined effects of temporal autocorrelation and the costs of plasticity on the evolution of plasticity

Mattias Siljestam & Örjan Östman
Adaptive phenotypic plasticity is an important source of intraspecific variation, and for many plastic traits the costs or factors limiting plasticity seem cryptic. However, there are several different factors that may constrain the evolution of plasticity, but few models have considered costs and limiting factors simultaneously. Here we use a simulation model to investigate how the optimal level of plasticity in a population depends on a fixed fitness cost for maintaining a potential for plasticity...

Data from: A potential pitfall in studies of biological shape: does size matter?

David Outomuro & Frank Johansson
1. The number of published studies using geometric morphometrics (GM) for analysing biological shape has increased steadily since the beginning of the 1990’s, covering multiple research areas such as ecology, evolution, development, taxonomy and palaeontology. Unfortunately, we have observed that many published studies using GM do not evaluate the potential allometric effects of size on shape, which normally require consideration or assessment This might lead to misinterpretations and flawed conclusions in certain cases, especially when...

Data from: Bringing ecology blogging into the scientific fold: measuring reach and impact of science community blogs

Manu E. Saunders, Meghan A. Duffy, Stephen B. Heard, Margaret Kosmala, Simon R. Leather, Terrence P. McGlynn, Jeff Ollerton & Amy L. Parachnowitsch
The popularity of science blogging has increased in recent years, but the number of academic scientists who maintain regular blogs is limited. The role and impact of science communication blogs aimed at general audiences is often discussed, but the value of science community blogs aimed at the academic community has largely been overlooked. Here, we focus on our own experiences as bloggers to argue that science community blogs are valuable to the academic community. We...

Data from: Devonian tetrapod-like fish reveals substantial parallelism in stem tetrapod evolution

Min Zhu, Per E. Ahlberg, Wen-Jin Zhao & Lian-Tao Jia
The fossils assigned to the tetrapod stem group document the evolution of terrestrial vertebrates from lobe-finned fishes. During the past 18 years the phylogenetic structure of this stem group has remained remarkably stable, even when accommodating new discoveries such as the earliest known stem tetrapod Tungsenia and the elpistostegid (fish–tetrapod intermediate) Tiktaalik. Here we present a large lobe-finned fish from the Late Devonian period of China that disrupts this stability. It combines characteristics of rhizodont...

Data from: Experimental evolution of slowed cognitive aging in Drosophila melanogaster

Martyna K. Zwoinska, Alexei A. Maklakov, Tadeusz J. Kawecki & Brian Hollis
Reproductive output and cognitive performance decline in parallel during aging, but it is unknown whether this reflects a shared genetic architecture or merely the declining force of natural selection acting independently on both traits. We used experimental evolution in Drosophila melanogaster to test for the presence of genetic variation for slowed cognitive aging, and assess its independence from that responsible for other traits’ decline with age. Replicate experimental populations experienced either joint selection on learning...

Data from: Whole-genome patterns of linkage disequilibrium across flycatcher populations clarify the causes and consequences of fine-scale recombination rate variation in birds

Takeshi Kawakami, Carina F. Mugal, Alexander Suh, Alexander Nater, Reto Burri, Linnea Smeds & Hans Ellegren
Recombination rate is heterogeneous across the genome of various species, and so are genetic diversity and differentiation as a consequence of linked selection. However, we still lack a clear picture of the underlying mechanisms for regulating recombination. Here we estimated fine-scale population recombination rate based on the patterns of linkage disequilibrium (LD) across the genomes of multiple populations of two closely related flycatcher species (Ficedula albicollis and F. hypoleuca). This revealed an overall conservation of...

Data from: Slow development as an evolutionary cost of long life

Martin I. Lind, Hwei-Yen Chen, Sara Meurling, Ana Cristina Guevara Gil, Hanne Carlsson, Martyna K. Zwoinska, Johan Andersson, Tuuli Larva & Alexei A. Maklakov
Life-history theory predicts a trade-off between early-life fitness and life span. While the focus traditionally has been on the fecundity-life span trade-off, there are strong reasons to expect trade-offs with growth rate and/or development time. We investigated the roles of growth rate and development time in the evolution of life span in two independent selection experiments in the outcrossing nematode Caenorhabditis remanei. First, we found that selection under heat-shock leads to the evolution of increased...

Data from: Organelles that illuminate the origins of Trichomonas hydrogenosomes and Giardia mitosomes

Michelle M. Leger, Martin Kolisko, Ryoma Kamikawa, Courtney W. Stairs, Keitaro Kume, Ivan Čepička, Jeffrey D. Silberman, Jan O. Andersson, Feifei Xu, Akinori Yabuki, Laura Eme, Qianqian Zhang, Kiyotaka Takishita, Yuji Inagaki, Alastair G. B. Simpson, Tetsuo Hashimoto & Andrew J. Roger
Many anaerobic microbial parasites possess highly modified mitochondria known as mitochondrion-related organelles (MROs). The best-studied of these are the hydrogenosomes of Trichomonas vaginalis and Spironucleus salmonicida, which produce ATP anaerobically through substrate-level phosphorylation with concomitant hydrogen production; and the mitosomes of Giardia intestinalis, which are functionally reduced and lack any role in ATP production. However, to understand the metabolic specializations that these MROs underwent in adaptation to parasitism, data from their free-living relatives are needed....

Data from: Paternal personality and social status influence offspring activity in zebrafish

Susanne Zajitschek, James E. Herbert-Read, Nasir M. Abbasi, Felix Zajitschek & Simone Immler
Background: Evidence for the transmission of non-genetic information from father to offspring is rapidly accumulating. While the impact of chemical and physical factors such as toxins or diet on the fitness of the parents and their offspring have been studied extensively, the importance of behavioural and social circumstances has only recently been recognised. Behavioural traits such as personality characteristics can be relatively stable, and partly comprise a genetic component but we know little about the...

Data from: Gene flow, ancient polymorphism, and ecological adaptation shape the genomic landscape of divergence among Darwin's finches

Fan Han, Sangeet Lamichhaney, B. Rosemary Grant, Peter R. Grant, Leif Andersson & Matthew T. Webster
Genomic comparisons of closely related species have identified “islands” of locally elevated sequence divergence. Genomic islands may contain functional variants involved in local adaptation or reproductive isolation and may therefore play an important role in the speciation process. However, genomic islands can also arise through evolutionary processes unrelated to speciation, and examination of their properties can illuminate how new species evolve. Here, we performed scans for regions of high relative divergence (FST) in 12 species...

Data from: DNA metabarcoding of orchid-derived products reveals widespread illegal orchid trade

Hugo J. De Boer, Abdolbaset Ghorbani, Vincent Manzanilla, Ancuta-Cristina Raclariu, Anna Kreziou, Sarawut Ounjai, Maslin Osathanunkul & Barbara Gravendeel
In eastern Mediterranean countries orchids continue to be collected from the wild for the production of salep, a beverage made of dried orchid tubers. In this study we used nrITS1 and nrITS2 DNA metabarcoding to identify orchid and other plant species present in 55 commercial salep products purchased in Iran, Turkey, Greece and Germany. Thirty samples yielded a total of 161 plant taxa, and 13 products (43%) contained orchid species and these belonged to 10...

Data from: Predation drives local adaptation of phenotypic plasticity

Julia Reger, Martin I. Lind, Matthew R. Robinson & Andrew P. Beckerman
Phenotypic plasticity is the ability of an individual genotype to alter aspects of its phenotype depending on the current environment. It is central to the persistence, resistance and resilience of populations facing variation in physical or biological factors. Genetic variation in plasticity is pervasive, which suggests its local adaptation is plausible. Existing studies on the adaptation of plasticity typically focus on single traits and a few populations, while theory about interactions among genes (for example,...

Data from: Post-metamorphic allometry in the earliest acrotretoid brachiopods from the lower Cambrian (Series 2) of South China, and its implications

Zhiliang Zhang, Zhifei Zhang, Lars E. Holmer & Feiyang Chen
The earliest growth of post-metamorphic (post-larval) shells in two species of Eohadrotreta is described from the Cambrian Shuijingtuo Formation of South China. Two different growth patterns can be observed by quantifying developmental variations in size and shape of successive stages of post-metamorphic shell growth (including the pedicle foramen forming stage, pedicle foramen enclosing stage and intertrough increasing stage) of Eohadrotreta zhenbaensis and Eohadrotreta? zhujiahensis. The pedicle foramen is never enclosed within the metamorphic shell of...

Data from: Evolutionary associations between host traits and parasite load: insights from Lake Tanganyika cichlids

Alexander Hayward, Masahito Tsuboi, Christian Owusu, Kotrschal Alexander, Severine D. Buechel, Josefina Zidar, Charlie K. Cornwallis, Hanne Lovlie, Niclas Kolm & A. Kotrschal
Parasite diversity and abundance (parasite load) vary greatly among host species. However, the influence of host traits on variation in parasitism remains poorly understood. Comparative studies of parasite load have largely examined measures of parasite species richness and are predominantly based on records obtained from published data. Consequently, little is known about the relationships between host traits and other aspects of parasite load, such as parasite abundance, prevalence and aggregation. Meanwhile, understanding of parasite species...

Data from: Ontogenetic timing as a condition-dependent life history trait: high-condition males develop quickly, peak early and age fast

Amy K. Hooper, Foteini Spagopoulou, Zachariah Gilmer Wylde, Alexei A. Maklakov, Russell Bonduriansky & Zachariah Wylde
Within-population variation in ageing remains poorly understood. In males, condition-dependent investment in secondary sexual traits may incur costs which limit ability to invest in somatic maintenance. Moreover, males often express morphological and behavioural secondary sexual traits simultaneously, but the relative effects on ageing of investment in these traits remain unclear. We investigated the condition-dependence of male life history in the neriid fly Telostylinus angusticollis. Using a fully factorial design, we manipulated male early-life condition by...

Data from: Interaction intensity and pollinator-mediated selection

Judith Trunschke, Nina Sletvold & Jon Agren
In animal-pollinated plants, the opportunity for selection and the strength of pollinator-mediated selection are expected to increase with the degree of pollen limitation. However, whether differences in pollen limitation can explain variation in pollinator-mediated and net selection among animal-pollinated species is poorly understood. In the present study, we quantified pollen limitation, variance in relative fitness and pollinator-mediated selection on five traits important for pollinator attraction (flowering start, plant height, flower number, flower size) and pollination...
