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: Local interactions and global properties of wild, free-ranging stickleback shoals

Ashley J. W. Ward, Timothy M. Schaerf, James E. Herbert-Read, Lesley Morrell, David J.T. Sumpter, Mike M. Webster & David J. T. Sumpter
Collective motion describes the global properties of moving groups of animals and the self-organized, coordinated patterns of individual behaviour that produce them. We examined the group-level patterns and local interactions between individuals in wild, free-ranging shoals of three-spine sticklebacks, Gasterosteus aculeatus. Our data reveal that the highest frequencies of near-neighbour encounters occur at between one and two body lengths from a focal fish, with the peak frequency alongside a focal individual. Fish also show the...

Data from: Covariation in levels of nucleotide diversity in homologous regions of the avian genome long after completion of lineage sorting

Ludovic Dutoit, Nagarjun Vijay, Carina F. Mugal, Christen M. Bossu, Reto Burri, Jochen Wolf & Hans Ellegren
Closely related species may show similar levels of genetic diversity in homologous regions of the genome owing to shared ancestral variation still segregating in the extant species. However, after completion of lineage sorting, such covariation is not necessarily expected. On the other hand, if the processes that govern genetic diversity are conserved, diversity may potentially covary even among distantly related species. We mapped regions of conserved synteny between the genomes of two divergent bird species—collared...

Data from: Sexual conflict and correlated evolution between male persistence and female resistance traits in the seed beetle Callosobruchus maculatus

Liam R. Dougherty, Emile Van Lieshout, Kathryn B. McNamara, Joe A. Moschilla, Göran Arnqvist & Leigh W. Simmons
Traumatic mating (or copulatory wounding) is an extreme form of sexual conflict whereby male genitalia physically harm females during mating. In such species females are expected to evolve counter-adaptations to reduce male-induced harm. Importantly, female counter-adaptations may include both genital and non-genital traits. In this study, we examine evolutionary associations between harmful male genital morphology and female reproductive tract morphology and immune function across 13 populations of the seed beetle Callosobruchus maculatus. We detected positive...

Data from: The interaction between predation risk and food ration on behavior and morphology of Eurasian perch

Richard Svanback, Yinghua Zha, Christer Brönmark & Frank Johansson
Both the risk of predation and food level have been shown to affect phenotypic development of organisms. However, these two factors also influence animal behavior that in turn may influence phenotypic development. Hence, it might be difficult to disentangle the behavioral effect from the predator or resource level effects. This is because the presence of predators and high resource levels usually results in a lower activity, which in turn affects energy expenditure that is used...

Data from: Does habitat specialization shape the evolutionary potential of wild bird populations?

Ivain Martinossi-Allibert, Joanne Clavel, Simon Ducatez, I. Le Viol & Celine Teplitsky
Because specialist species evolved in more temporally and spatially homogeneous environments than generalist species, they are supposed to experience less fluctuating selection. For this reason, we expect specialists to show lower overall genetic variation as compared to generalists. We also expect populations from specialist species to be smaller and more fragmented, with lower neutral genetic diversity. We tested these hypotheses by investigating patterns of genetic diversity along a habitat specialization gradient in wild birds, based...

Data from: Body size affects the strength of social interactions and spatial organization of a schooling fish (Pseudomugil signifer)

Maksym Romenskyy, James E. Herbert-Read, Ashley J. W. Ward, David J.T. Sumpter & David J. T. Sumpter
While a rich variety of self-propelled particle models propose to explain the collective motion of fish and other animals, rigorous statistical comparison between models and data remains a challenge. Plausible models should be flexible enough to capture changes in the collective behaviour of animal groups at their different developmental stages and group sizes. Here, we analyse the statistical properties of schooling fish (Pseudomugil signifer) through a combination of experiments and simulations. We make novel use...

Data from: Automated deep-phenotyping of the vertebrate brain

Amin Allalou, Yuelong Wu, Mostafa Ghannad-Rezaie, Peter M. Eimon, Mehmet Faith Yanik & Mehmet Fatih Yanik
Here we describe an automated platform suitable for large-scale deep-phenotyping of zebrafish mutant lines, which uses optical projection tomography to rapidly image brain-specific gene expression patterns in 3D at cellular resolution. Registration algorithms and correlation analysis are then used to compare 3D expression patterns, to automatically detect all statistically significant alterations in mutants, and to map them onto a brain atlas. Automated deep-phenotyping of a mutation in the master transcriptional regulator fezf2 not only detects...

Data from: Veronica officinalis product authentication using DNA metabarcoding and HPLC-MS reveals widespread adulteration with Veronica chamaedrys

Ancuta C. Raclariu, Andrei Mocan, Madalina Oana Popa, Laurian Vlase, Mihael C. Ichim, Gianina Crisan, Anne Krag Brysting & Hugo De Boer
Studying herbal products derived from local and traditional knowledge and their value chains is one of the main challenges in ethnopharmacology. The majority of these products have a long history of use, but non-harmonized trade and differences in regulatory policies between countries impact their value chains and lead to concerns over product efficacy, safety and quality. Veronica officinalis L. (common speedwell), a member of Plantaginaceae family, has a long history of use in European traditional...

Data from: Insights into the genetic architecture of morphological traits in two passerine bird species

Catarina N. S. Silva, S. Eryn McFarlane, Ingerid J. Hagen, Lars Rönnegård, Anna M. Billing, Thomas Kvalnes, Petri Kemppainen, Bernt Rønning, Thor Harald Ringsby, Bernt-Erik Sæther, Anna Qvarnström, Hans Ellegren, Henrik Jensen & Arild Husby
Knowledge about the underlying genetic architecture of phenotypic traits is needed to understand and predict their evolutionary dynamics. The number of causal loci, magnitude of their effects and location in the genome is however still largely unknown. Here we use genome-wide SNP data from two large-scale datasets on house sparrows and collared flycatchers to examine the genetic architecture of different morphological traits (tarsus length, wing length, body mass, bill depth, bill length, total and visible...

Data from: Climate and anthropogenic factors determine site occupancy in Scotland's Northern-range badger population: implications of context-dependent responses under environmental change

André P. Silva, Gonçalo Curveira-Santos, Kerry Kilshaw, Chris Newman, David W. Macdonald, Luciana G. Simões & Luís M. Rosalino
Aim In the light of human-induced rapid environmental change (HIREC), populations are exposed to ever-greater bioclimatic stress at the edge of a species’ historic range. The distribution dynamics of European badgers (Meles meles) at their southern edge are linked tightly to climatic variability. We contribute critical data on how climatic context and local factors determine site occupancy in a northern-range population. Location Eleven study areas (averaging ~21.3 km2) spread over ~50,000 km2 in Northern Scotland....

Data from: A crush on small fungi: an efficient and quick method for obtaining DNA from minute ascomycetes

Henrik Sundberg, Stefan Ekman & Åsa Kruys
1. We have developed a reliable technique for extracting DNA from single microscopic fungal thalli, including efficient cell disruption and transfer of cell content for subsequent polymerase chain reaction (PCR). The technique was primarily developed for members of the ascomycete order Laboulbeniales, which are minute fungi with tough cell walls that are exceedingly difficult to disrupt with standard extraction techniques. 2. Our method makes routine amplification of DNA from single thalli possible, even from small...

Data from: Specificity of fungal associations of Pyroleae and Monotropa hypopitys during germination and seedling development

Veronika A Johansson, Mohammad Bahram, Leho Tedersoo, Urmas Köljalg & Ove Eriksson
Mycoheterotrophic plants obtain organic carbon from associated mycorrhizal fungi, fully or partially. Angiosperms with this form of nutrition possess exceptionally small 'dust seeds' which after germination develop 'seedlings' that remain subterranean for several years, fully dependent on fungi for supply of carbon. Mycoheterotrophs which as adults have photosynthesis thus develop from full to partial mycoheterotrophy, or autotrophy, during ontogeny. Mycoheterotrophic plants may represent a gradient of variation in a parasitism-mutualism continuum, both among and within...

Data from: Hoverfly locomotor activity is resilient to external influence and intrinsic factors

Malin Thyselius & Karin Nordström
Hoverflies are found across the globe, with approximately 6000 species described worldwide. Many hoverflies are being used in agriculture and some are emerging as model species for laboratory experiments. As such it is valuable to know more about their activity. Like many other dipteran flies, Eristalis hoverflies have been suggested to be strongly diurnal, but this is based on qualitative visualization by human observers. To quantify how hoverfly activity depends on internal and external factors,...

Data from: Evolution of the selfing syndrome: anther orientation and herkogamy together determine reproductive assurance in a self-compatible plant

Per Toräng, Linus Vikström, Jörg Wunder, Stefan Wötzel, George Coupland & Jon Ågren
Capacity for autonomous self-fertilization provides reproductive assurance, has evolved repeatedly in the plant kingdom, and typically involves several changes in flower morphology and development (the selfing syndrome). Yet, the relative importance of different traits and trait combinations for efficient selfing and reproductive success in pollinator-poor environments is poorly known. In a series of experiments, we tested the importance of anther-stigma distance and the less studied trait anther orientation for efficiency of selfing in the perennial...

Data from: Enzyme architecture: modeling the operation of a hydrophobic clamp in catalysis by triosephosphate isomerase

Yashraj S. Kulkarni, Qinghua Liao, Dušan Petrovic, Dennis M. Krüger, Birgit Strodel, Tina L. Amyes, John P. Richard & Shina Caroline Lynn Kamerlin
Triosephosphate isomerase (TIM) is a proficient catalyst of the reversible isomerization of dihydroxyacetone phosphate (DHAP) to d-glyceraldehyde phosphate (GAP), via general base catalysis by E165. Historically, this enzyme has been an extremely important model system for understanding the fundamentals of biological catalysis. TIM is activated through an energetically demanding conformational change, which helps position the side chains of two key hydrophobic residues (I170 and L230), over the carboxylate side chain of E165. This is critical...

Data from: Cope’s rule and the adaptive landscape of dinosaur body size evolution

Roger B. J. Benson, Gene Hunt, Matthew T. Carrano & Nicolás Campione
The largest known dinosaurs weighed at least 20 million times as much as the smallest, indicating exceptional phenotypic divergence. Previous studies have focused on extreme giant sizes, tests of Cope's rule, and miniaturization on the line leading to birds. We use non-uniform macroevolutionary models based on Ornstein–Uhlenbeck and trend processes to unify these observations, asking: what patterns of evolutionary rates, directionality and constraint explain the diversification of dinosaur body mass? We find that dinosaur evolution...
