Data from: Associations among elementary school children's actual motor competence, perceived motor competence, physical activity and BMI: a cross-sectional study

An De Meester, David Stodden, Ali Brian, Larissa True, Greet Cardon, Isabel Tallir & Leen Haerens
Background: Positive associations between motor competence and physical activity have been identified by means of variable-centered analyses. To expand the understanding of these associations, this study used a person-centered approach to investigate whether different combinations (i.e., profiles) of actual and perceived motor competence exist (aim 1); and to examine differences in physical activity levels (aim 2) and weight status (aim 3) among children with different motor competence-based profiles. Methods: Children's (N=361; Boys=50%; Mage=9.50±1.24yrs) actual motor...

Data from: Sexual cannibalism increases male material investment in offspring: quantifying terminal reproductive effort in a praying mantis

William D. Brown & Katherine L. Barry
Models of the evolution of sexual cannibalism argue that males may offset the cost of cannibalism if components of the male body are directly allocated to the eggs that they fertilize. We tested this idea in the praying mantid Tenodera sinensis. Males and females were fed differently radiolabelled crickets and allowed to mate. Half of the pairs progressed to sexual cannibalism and we prevented cannibalism in the other half. We assess the relative allocation of...

Data from: Multi-locus analyses reveal four giraffe species instead of one

Julian Fennessy, Tobias Bidon, Friederike Reuss, Vikas Kumar, Paul Elkan, Maria A. Nilsson, Melita Vamberger, Uwe Fritz & Axel Janke
Traditionally, one giraffe species and up to eleven subspecies have been recognized [ 1 ]; however, nine subspecies are commonly accepted [ 2 ]. Even after a century of research, the distinctness of each giraffe subspecies remains unclear, and the genetic variation across their distribution range has been incompletely explored. Recent genetic studies on mtDNA have shown reciprocal monophyly of the matrilines among seven of the nine assumed subspecies [ 3, 4 ]. Moreover, until...

Data from: Amino acid change in an orchid desaturase enables mimicry of the pollinator’s sex pheromone

Khalid E. M. Sedeek, Edward Whittle, Daniela Guthörl, Ueli Grossniklaus, John Shanklin & Philipp Schlüter
Mimicry illustrates the power of selection to produce phenotypic convergence in biology [ 1 ]. A striking example is the imitation of female insects by plants that are pollinated by sexual deception of males of the same insect species [ 2–4 ]. This involves mimicry of visual, tactile, and chemical signals of females [ 2–7 ], especially their sex pheromones [ 8–11 ]. The Mediterranean orchid Ophrys exaltata employs chemical mimicry of cuticular hydrocarbons, particularly...

Data from: Initial genetic diversity enhances population establishment and alters genetic structuring of a newly established Daphnia metapopulation

Christopher J. Holmes, Jelena H. Pantel, Kimberly L. Schulz & Carla E. Cáceres
When newly created habitats are initially colonized by genotypes with rapid population growth rates, later arriving colonists may be prevented from establishing. Although these priority effects have been documented in multiple systems, their duration may be influenced by the diversity of the founding population. We conducted a large-scale field manipulation to investigate how initial clonal diversity influences temporal and landscape patterns of genetic structure in a developing metapopulation. Six genotypes of obligately asexual Daphnia pulex...

Data from: Agreements between industry and academia on publication rights: a retrospective study of protocols and publications of randomized clinical trials

Benjamin Kasenda, Erik Von Elm, John J. You, Anette Blümle, Yuki Tomonaga, Ramon Saccilotto, Alain Amstutz, Theresa Bengough, Joerg J. Meerpohl, Mihaela Stegert, Kelechi K. Olu, Kari A. O. Tikkinen, Ignacio Neumann, Alonso Carrasco-Labra, Markus Faulhaber, Sohail M. Mulla, Dominik Mertz, Elie A. Akl, Dirk Bassler, Jason W. Busse, Ignacio Ferreira-González, Francois Lamontagne, Alain Nordmann, Viktoria Gloy, Heike Raatz … & Matthias Briel
Background: Little is known about publication agreements between industry and academic investigators in trial protocols and the consistency of these agreements with corresponding statements in publications. We aimed to investigate (i) the existence and types of publication agreements in trial protocols, (ii) the completeness and consistency of the reporting of these agreements in subsequent publications, and (iii) the frequency of co-authorship by industry employees. Methods and Findings: We used a retrospective cohort of randomized clinical...

Data from: New information on Titanichthys (Placodermi: Arthrodira) from the Cleveland shale (upper devonian) of Ohio, USA

James Boyle & Michael Ryan
The placoderm (Titanichthys) from the Late Devonian (Famennian) is based on incomplete and fragmentary specimens that have hindered understanding of its overall anatomy and phylogenetic relationships. A new, nearly complete, articulated specimen from the Upper Devonian Cleveland Shale provides new information about the previously undescribed rostral, postmarginal, postsuborbital, submarginal, posterior superognathal plates, and the nasal capsule. A revised diagnosis is provided for the genus. Three new diagnostic characters are identified including a transversely elliptical rostral...

Data from: Ungulate distributions in a rangeland with competitors, predators, and pastoralists

Paul Schuette, Scott Creel & Dave Christianson
African rangelands support diverse ungulate communities whose member species exhibit unique combinations of body morphology and behaviour that have evolved over millions of years to limit the effects of competition and predation on fitness, and more recently, to cope with people and livestock. The mechanisms by which native ungulates cope with the combined effects of competition, predation and human disturbance are poorly understood. Addressing this knowledge gap will help guide management and conservation plans for...

Data from: Biomass resilience of Neotropical secondary forests

Chazdon, Dylan Craven, Jarcilene S. De Almeida-Cortez, George A. L. Cabral, Ben H. J. De Jong, Julie S. Denslow, Daisy H. Dent, Saara J. DeWalt, Juan M. Dupuy, Sandra M. Durán, Mario M. Espírito-Santo, María C. Fandino, Ricardo G. César, Jefferson S. Hall, José Luis Hernandez-Stefanoni, Catarina C. Jakovac … & Danaë M. A. Rozendaal
Land-use change occurs nowhere more rapidly than in the tropics, where the imbalance between deforestation and forest regrowth has large consequences for the global carbon cycle1. However, considerable uncertainty remains about the rate of biomass recovery in secondary forests, and how these rates are influenced by climate, landscape, and prior land use2, 3, 4. Here we analyse aboveground biomass recovery during secondary succession in 45 forest sites and about 1,500 forest plots covering the major...

Data from: Assessing niche conservatism using a multiproxy approach: dietary ecology of extinct and extant spotted hyenas

Larisa R. G. DeSantis, Zhijie Jack Tseng, Jinyi Liu, Aaron Hurst, Blaine Schubert & Qigao Jiangzuo
A central premise of bioclimatic envelope modeling is the assumption of niche conservatism. Whereas such assumptions are testable in modern populations, it is unclear if niche conservatism holds over deeper time spans and over very large geographic ranges. Hyaenids occupied a diversity of ecological niches over time and space, and until the end-Pleistocene they occurred in Europe and most of Asia, with Asian populations of Crocuta suggested as being genetically distinct from their closest living...
