Data from: A comprehensive and user-friendly framework for 3D-data visualisation in invertebrates and other organisms

Thomas L. Semple, Rod Peakall & Nikolai J. Tatarnic
Methods for 3D‐imaging of biological samples are experiencing unprecedented development, with tools such as X‐ray micro‐computed tomography (μCT) becoming more accessible to biologists. These techniques are inherently suited to small subjects and can simultaneously image both external and internal morphology, thus offering considerable benefits for invertebrate research. However, methods for visualising 3D‐data are trailing behind the development of tools for generating such data. Our aim in this article is to make the processing, visualisation and...

Data from: Characterizing morphological (co)variation using structural equation models: body size, allometric relationships and evolvability in a house sparrow metapopulation

Yimen Gerardo Araya-Ajoy, Peter S. Sjolte Ranke, Thomas Kvalnes, Bernt Rønning, Håkon Holand, Ane Marlene Myhre, Henrik Pärn, Henrik Jensen, Thor Harald Ringsby, Bernt-Erik Saether & Jonathan Wright
Body size plays a key role in the ecology and evolution of all organisms. Therefore, quantifying the sources of morphological (co)variation, dependent and independent of body size, is of key importance when trying to understand and predict responses to selection. We combine structural equation modeling with quantitative genetics analyses to study morphological (co)variation in a meta-population of house sparrows (Passer domesticus). As expected, we found evidence of a latent variable ‘body size’, causing genetic and...

Data from: Hyperabundant herbivores limit habitat availability and influence nest-site selection of Arctic-breeding birds

Scott A. Flemming, Erica Nol, Lisa V. Kennedy & Paul A. Smith
1. Understanding an organism’s habitat selection and behavioural flexibility in the face of environmental change can help managers plan for future conservation of that species. Hyperabundant tundra-nesting geese are influencing Arctic environments through their foraging activities. Goose-induced habitat change in Arctic wetlands may influence the availability of habitat for numerous shorebird species that breed sympatrically with geese. 2. Here, we explore whether goose-induced habitat alteration affects shorebird breeding density and nest-site selection. Using habitat data...

Data from: Genomic selection of juvenile height across a single generational gap in Douglas-fir

Frances R. Thistlethwaite, Blaise Ratcliffe, Jaroslav Klápště, Ilga Porth, Charles Chen, Michael U. Stoehr & Yousry A. El-Kassaby
Here we perform cross-generational GS analysis on coastal Douglas-fir (Pseudotsuga menziesii), reflecting trans-generational selective breeding application. 1,321 trees, representing 37 full-sib F1 families from 3 environments in British Columbia, Canada, were used as the training population for 1) EBVs (estimated breeding values) of juvenile height (HTJ) in the F1 generation predicting genomic EBVs of HTJ of 136 individuals in the F2 generation, 2) deregressed EBVs of F1 HTJ predicting deregressed genomic EBVs of F2 HTJ,...

Data from: Marine invertebrate migrations trace climate change over 450 million years. UPDATED

Carl J Reddin, Ádám T Kocsis & Wolfgang Kiessling
Note: scored-through sections represent updates to the methods (see Dryad Methods section) Aim: Poleward migration is a clear response of marine organisms to current global warming but the generality and geographical uniformity of this response are unclear. Marine fossils are expected to record the range shift responses of taxa and ecosystems to past climate change. However, unequal sampling (natural and human) in time and space biases the fossil record, restricting previous studies of ancient migrations...

Data from: Electrophysiological correlates of semantic dissimilarity reflect the comprehension of natural, narrative speech

Michael P. Broderick, Andrew J. Anderson, Giovanni M. Di Liberto, Michael J. Crosse & Edmund C. Lalor
People routinely hear and understand speech at rates of 120–200 words per minute [1, 2]. Thus, speech comprehension must involve rapid, online neural mechanisms that process words’ meanings in an approximately time-locked fashion. However, in the context of continuous speech, electrophysiological evidence for such time-locked processing has been lacking. Whilst valuable insights into the semantic processing of speech have been provided by the “N400 component” of the event-related potential [3-6], this literature has been dominated...

Data from: Foraging efficiency and size matching in a plant – pollinator community: the importance of sugar content and tongue length

Saskia G.T. Klumpers, Martina Stang & Peter G.L. Klinkhamer
A longstanding question in ecology is how species interactions are structured within communities. Although evolutionary theory predicts close size matching between floral nectar tube depth and pollinator proboscis length of interacting species, such size matching has seldom been shown and explained in multispecies assemblages. Here, we investigated the degree of size matching among Asteraceae and their pollinators and its relationship with foraging efficiency. The majority of pollinators, especially Hymenoptera, choose plant species on which they...

Data from: Mutualists stabilize coexistence of congeneric legumes

Andrew Siefert, Kenneth W. Zillig, Maren L. Friesen & Sharon Y. Strauss
Coexistence requires that stabilizing niche differences, which cause species to limit themselves more than others, outweigh relative fitness differences that cause competitive exclusion. Interactions with shared mutualists, which can differentially affect host fitness and change in magnitude with host frequency, can satisfy these conditions for coexistence, yet empirical tests of mutualist effects on relative fitness and stabilizing niche differences are largely lacking within the framework of coexistence theory. Here, we show that N-fixing rhizobial mutualists...

Geographic patterns in morphometric and genetic variation for coyote populations with emphasis on southeastern coyotes

Joseph W Hinton, Elizabeth Heppenheimer, Danny Caudill, Melissa L Karlin, Margaret Walch, Bridgett VonHoldt, Michael J Chamberlain, Kyla M. West, John C. Kilgo, John Joseph Mayer & Karl V. Miller
Prior to 1900, coyotes (Canis latrans) were restricted to the western and central regions of North America, but by the early 2000s coyotes became ubiquitous throughout the eastern United States. Information regarding morphological and genetic structure of coyote populations in the southeastern United States is limited, and where data exist, they are rarely compared to those from other regions of North America. We assessed geographic patterns in morphology and genetics of coyotes with special consideration...

Data from: Assessment of polytraumatized patients according to the Berlin Definition: Does the addition of physiological data really improve interobserver reliability?

Carina Eva Maria Pothmann, Stephen Baumann, Kai Oliver Jensen, Ladislav Mica, Georg Osterhoff, Hans Peter Simmen & Kai Sprengel
Background Several new definitions for categorizing the severely injured as the Berlin Definition have been developed. Here, severely injured patients are selected by additive physiological parameters and by the general Abbreviated Injury Scale (AIS)-based assessment. However, all definitions should conform to an AIS severity coding applied by an expert. We examined the dependence of individual coding on defining injury severity in general and in identifying polytrauma according to several definitions. A precise definition of polytrauma...

Data from: Genome sequence of M6, a diploid inbred clone of the high glycoalkaloid-producing tuber-bearing potato species Solanum chacoense, reveals residual heterozygosity

Courtney P. Leisner, John P. Hamilton, Emily Crisovan, Norma C Manrique-Carpintero, Alexandre P. Marand, Linsey Newton, Gina M. Pham, Jiming Jiang, David S. Douches, Shelley H. Jansky & C. Robin Buell
Cultivated potato (Solanum tuberosum L.) is a highly heterozygous autotetraploid that presents challenges in genome analyses and breeding. Wild potato species serve as a resource for the introgression of important agronomic traits into cultivated potato. One key species is Solanum chacoense and the diploid, inbred clone M6, which is self-compatible and has desirable tuber market quality and disease resistance traits. Sequencing and assembly of the genome of the M6 clone of S. chacoense generated an...

Data from: Evidence of host-associated divergence from coral-eating snails (genus Coralliophila) in the Coral Triangle

Sara E. Simmonds, Vincent Chou, Samantha H. Cheng, Rita Rachmawati, Hilconida P. Campulong, Paul H. Barber, Hilconida P. Calumpong & G. Ngurah Mahardika
We studied how host-associations and geography shape the genetic structure of sister species of marine snails Coralliophila radula (A. Adams, 1853) and C. violacea (Kiener, 1836). These obligate ectoparasites prey upon corals and are sympatric throughout much of their ranges in coral reefs of the tropical and subtropical Indo-Pacific. We tested for population genetic structure of snails in relation to geography and their host corals using mtDNA (COI) sequences in minimum spanning trees and AMOVAs....

Data from: Plasma mammalian leptin analogue predicts reproductive phenology, but not reproductive output in a capital-income breeding seaduck

Holly Hennin, Pierre Legagneux, Hugh Gilchrist, Joël Bêty, John McMurtry & Oliver P. Love
To invest in energetically demanding life history stages, individuals require a substantial amount of resources. Physiological traits, particularly those related to energetics, can be useful for examining variation in life history decisions and trade-offs because they result from individual responses to environmental variation. Leptin is a protein hormone found in mammals that is proportional to the amount of endogenous fat stores within an individual. Recently, researchers have confirmed that a mammalian leptin analogue (MLA), based...

Data from: Whooping crane use of riverine stopover sites

David M. Baasch
Migratory birds like endangered whooping cranes (Grus americana) require suitable nocturnal roost sites during twice annual migrations. Whooping cranes primarily roost in shallow surface water wetlands, ponds, and rivers. All these features have been greatly impacted by human activities, which present threats to the continued recovery of the species. A portion of one such river, the central Platte River, has been identified as critical habitat for the survival of the endangered whooping crane. Management intervention...

Flavia A. Esteves, Fredrik Palmkron & Brian L. Fisher
A total of 105 ant species from 54 genera and 10 subfamilies have been identified from the collections made during the 2017 assessment of ants of Penang Hill, Malaysia. Additional work is ongoing to process and identify the remaining samples, which will undoubtedly raise the total number of species. Our data add to a growing dataset on the ant fauna of peninsular Malaysia. Ants play important roles as predators, scavengers, and seed dispersers in tropical...

Data from: The mediating effect of action planning on physical activity behaviors of university students in South Korea: based on an integrated theory

H. Y. Kim & Jae Young Yang
Background: The main concern in many countries is to increase physical activity levels of adolescent populations in terms of prevention of obesity and adult disease. Physical activity levels of university students in South Korea have decreased remarkably in recent years. The motivation process has been regarded as a key factor for the understanding of participation and maintenance in physical activity. As a research gap discovered in previous studies, the exploration of motivational processes including multiple...

Data from: Evaluation of parametric and nonparametric machine-learning techniques for prediction of saturated and near-saturated hydraulic conductivity

Ali Mehmandoost Kotlar, Bo V. Iversen & Quirijn De Jong Van Lier
Parametric and nonparametric supervised machine learning techniques were used to estimate saturated and near saturated hydraulic conductivities (Ks, K10) from easily measurable soil properties including name of pedological horizon (HOR), soil texture (sand, silt & clay), organic matter (OM), bulk density (BD) and water contents (θpF1, θpF2, θpF3 and, θpF4.2) measured at four different matric heads (-10, -100, -1000, and -15848 cm). Using a stepwise linear model (SWLM) and the Lasso regression as parametric methods...

Data from: A curious new species of Xenostegia (Convolvulaceae) from Central Africa, with remarks on the phylogeny of the genus

Marc Sosef, Roy E. Gereau, Steven B. Janssens, Modestine Kompanyi & Ana R. Simões
The polymorphic genus Merremia Dennst. ex Endl. has been shown to be polyphyletic. In 1980, Xenostegia D.F.Austin & Staples was separated from the first, based on its longitudinally dehiscing anthers, stigmas with long tapering papillae, and non-spiny, pantoporate pollen, and accommodated two species in the Old World tropics. A recent molecular study and subsequent review of the tribe Merremieae resulted in the distinction of seven genera and corroborated the delimitation of Xenostegia at genus level,...

Data from: Coastal acidification impacts on shell mineral structure of bivalve molluscs

Susan C. Fitzer, Sergio Torres Gabarda, Luke Daly, Brian Hughes, Michael Dove, Wayne O'Connor, Jaimie Potts, Peter Scanes & Maria Byrne
Ocean acidification is occurring globally through increasing CO2 absorption into the oceans creating particular concern for calcifying species. In addition to ocean acidification, near shore marine habitats are exposed to the deleterious effects of runoff from acid sulphate soils which also decreases environmental pH. This coastal acidification is being exacerbated by climate change driven sea-level rise and catchment-driven flooding. In response to reduction in habitat pH by ocean and coastal acidification molluscs are predicted to...

Data from: Seed priming and Zaï pit practice improve field performance of sorghum (Sorghum bicolor L. Moench) in the Sahelian zone of Mali

Siaka S Dembele
Poor seed germination caused by a variety of seed, soil and environmental factors lead to suboptimal seedling stand and ultimately yield suffers a serious setback. A number of priming techniques have been found to be effective in increasing germination and seedling growth and development. This includes techniques such as on-farm hydro-priming (seed soaking in well water) and osmo-priming (seed soaking in low osmotic solutions of Potassium silicate). Also, Zaï practice, a cropping system concentrating runoff...

Data from: Accelerating seed germination and seedling development of Sorghum (Sorghum bicolor L. Moench) through hydro-priming

Siaka S. Dembele
Mali is a Sahelian country in West Africa, characterized by a strong dependence on rain-fed agriculture and a low adaptive capacity, making it one of the most vulnerable regions to climate change worldwide. Moreover, most climate models used for the region recognize a growing uncertainty in the onset of the rainy season, which demands urgent adaptation measures. Early-season drought limits crops germination, and hence growth, and yield during rain-fed depending production as commonly experienced nowadays...
