Data from: Experimental and statistical reevaluation provides no evidence for Drosophila courtship song rhythms

David L. Stern, Jan Clemens, Philip Coen, Adam J. Calhoun, John B. Hogenesch, Ben J. Arthur & Mala Murthy
From 1980 to 1992, a series of influential papers reported on the discovery, genetics, and evolution of a periodic cycling of the interval between Drosophila male courtship song pulses. The molecular mechanisms underlying this periodicity were never described. To reinitiate investigation of this phenomenon, we previously performed automated segmentation of songs but failed to detect the proposed rhythm [Arthur BJ, et al. (2013) BMC Biol 11:11; Stern DL (2014) BMC Biol 12:38]. Kyriacou et al....

Data from: Assessing the conservation value of secondary savanna for large mammals in the Brazilian Cerrado

Guilherme B. Ferreira, Jorge A. Ahumada, Marcelo J. R. Oliveira, Fernando F. De Pinho, Izabela M. Barata, Chris Carbone & Ben Collen
Debate about the conservation value of secondary habitats has tended to focus on tropical forests, increasingly recognizing the role of secondary forests for biodiversity conservation. However, there remains a lack of information about the conservation value of secondary savannas. Here, we conducted a camera trap survey to assess the effect of secondary vegetation on large mammals in a Brazilian Cerrado protected area, using a single-season occupancy framework to investigate the response of individual species (species-level...

Data from: A map of abstract relational knowledge in the human hippocampal–entorhinal cortex

Mona M. Garvert, Raymond J. Dolan, Timothy E.J. Behrens & Timothy EJ Behrens
The hippocampal–entorhinal system encodes a map of space that guides spatial navigation. Goal-directed behaviour outside of spatial navigation similarly requires a representation of abstract forms of relational knowledge. This information relies on the same neural system, but it is not known whether the organisational principles governing continuous maps may extend to the implicit encoding of discrete, non-spatial graphs. Here, we show that the human hippocampal–entorhinal system can represent relationships between objects using a metric that...

Data from: Human visual exploration reduces uncertainty about the sensed world

M. Berk Mirza, Rick A. Adams, Christoph Mathys & Karl J. Friston
In previous papers, we introduced a normative scheme for scene construction and epistemic (visual) searches based upon active inference. This scheme provides a principled account of how people decide where to look, when categorising a visual scene based on its contents. In this paper, we use active inference to explain the visual searches of normal human subjects; enabling us to answer some key questions about visual foraging and salience attribution. First, we asked whether there...

Data from: A genome for gnetophytes and early evolution of seed plants

Tao Wan, Zhi-Ming Liu, Ling-Fei Li, Andrew R. Leitch, Ilia J. Leitch, Rolf Lohaus, Zhong-Jian Liu, Hai-Ping Xin, Yan-Bing Gong, Yang Liu, Wen-Cai Wang, Ling-Yun Chen, Yong Yang, Laura J. Kelly, Ji Yang, Jin-Ling Huang, Zhen Li, Ping Liu, Li Zhang, Hong-Mei Liu, Hui Wang, Shu-Han Deng, Meng Liu, Ji Li, Lu Ma … & Xiao-Ming Wang
Gnetophytes are an enigmatic gymnosperm lineage comprising three genera, Gnetum, Welwitschia and Ephedra, which are morphologically distinct from all other seed plants. Their distinctiveness has triggered much debate as to their origin, evolution and phylogenetic placement among seed plants. To increase our understanding of the evolution of gnetophytes, and their relation to other seed plants, we report here a high-quality draft genome sequence for Gnetum montanum, the first for any gnetophyte. By using a novel...

Data from: Variation in the benefits of multiple mating on female fertility in wild stalk-eyed flies

Lara Meade, Elisabeth Harley, Alison Cotton, James Howie, Andrew Pomiankowski, Kevin Fowler & James M. Howie
Polyandry, female mating with multiple males, is widespread across many taxa and almost ubiquitous in insects. This conflicts with the traditional idea that females are constrained by their comparatively large investment in each offspring, and so should only need to mate once or a few times. Females may need to mate multiply to gain sufficient sperm supplies to maintain their fertility, especially in species in which male promiscuity results in division of their ejaculate amongst...

Data from: Parental investment in a Tibetan population does not reflect stated cultural norms

Juan Du & Ruth Mace
In this paper, we examined both stated norms of gender preference and actual sex-biases in parental investment in a Tibetan pastoralist society. We collected detailed demographic data to examine how biased parental investment had an effect on infant mortality, infant feeding, the length of interbirth intervals and a decision when giving gifts. Our results indicate a mismatch between self-reported son preference and measures of actual parental investment that favour daughters. We interpret this female-biased parental...

Data from: Smart wing rotation and trailing-edge vortices enable high frequency mosquito flight

Richard J. Bomphrey, Toshiyuki Nakata, Nathan Phillips & Simon M. Walker
Mosquitoes exhibit unusual wing kinematics; their long, slender wings flap at remarkably high frequencies for their size (>800 Hz)and with lower stroke amplitudes than any other insect group1. This shifts weight support away from the translation-dominated, aerodynamic mechanisms used by most insects2, as well as by helicopters and aeroplanes, towards poorly understood rotational mechanisms that occur when pitching at the end of each half-stroke. Here we report free-flight mosquito wing kinematics, solve the full Navier–Stokes...

Data from: Completeness of the eutherian mammal fossil record and implications for reconstructing mammal evolution through the Cretaceous/Paleogene mass extinction

Thomas W. Davies, Mark A. Bell, Anjali Goswami & Thomas J.D. Halliday
There is a well-established discrepancy between paleontological and molecular data regarding the timing of the origin and diversification of placental mammals. Molecular estimates place interordinal diversification dates in the Cretaceous, whilst no unambiguous crown placental fossils have been found prior to the end-Cretaceous mass extinction. Here, the completeness of the eutherian fossil record through geological time is evaluated in order to assess the suggestion that a poor fossil record is largely responsible for the difference...

Data from: The complexity of mating decisions in stalk-eyed flies

Nadine C. Chapman, Penthai Siriwat, James Howie, Aaron Towlson, Lawrence Bellamy, Kevin Fowler & Andrew Pomiankowski
All too often, studies of sexual selection focus exclusively on the responses in one sex, on single traits, typically those that are exaggerated and strongly sexually dimorphic. They ignore a range of less obvious traits and behavior, in both sexes, involved in the interactions leading to mate choice. To remedy this imbalance, we analyze a textbook example of sexual selection in the stalk-eyed fly (Diasemopsis meigenii). We studied several traits in a novel, insightful, and...

Data from: A prioritised list of invasive alien species to assist the effective implementation of EU legislation

Carles Carboneras, Piero Genovesi, Montserrat Vila, Tim Blackburn, Martina Carrete, Miguel Clavero, Bram D'hondt, Jorge F. Orueta, Belinda Gallardo, Pedro Geraldes, Pablo González-Moreno, Richard D. Gregory, Wolfgang Nentwig, Jean-Yves Paquet, Petr Pysek, Wolfgang Rabitsch, Iván Ramírez, Riccardo Scalera, Jose Tella, Paul Walton, Robin Wynde & Tim M. Blackburn
1. Effective prevention and control of invasive species generally relies on a comprehensive, coherent and representative list of species that enables resources to be used optimally. European Union (EU) Regulation 1143/2014 on invasive alien species (IAS) aims to control or eradicate priority species, and to manage pathways to prevent the introduction and establishment of new IAS; it applies to species considered of Union concern and subject to formal risk assessment. So far, 49 species have...

Data from: Shotgun mitogenomics across body size classes in a local assemblage of tropical Diptera: phylogeny, species diversity and mitochondrial abundance spectrum

Le Qin Choo, Alex Crampton-Platt & Alfried P. Vogler
Mitochondrial genomes can be assembled readily from shotgun-sequenced DNA mixtures of mass-trapped arthropods (“mitochondrial metagenomics”), speeding up the taxonomic characterization. Bulk sequencing was conducted on some 800 individuals of Diptera obtained by canopy fogging of a single tree in Borneo dominated by small (<1.5 mm) individuals. Specimens were split into five body size classes for DNA extraction, to equalize read numbers across specimens and to study how body size, a key ecological trait, interacts with...

Data from: Sex and genotype effects on nutrient-dependent fitness landscapes in Drosophila melanogaster

M. Florencia Camus, Kevin Fowler, Matthew W.D. Piper, Max Reuter & Matthew W. D. Piper
The sexes perform different reproductive roles and have evolved sometimes strikingly different phenotypes. One focal point of adaptive divergence occurs in the context of diet and metabolism, and males and females of a range of species have been shown to require different nutrients to maximize their fitness. Biochemical analyses in Drosophila melanogaster have confirmed that dimorphism in dietary requirements is associated with molecular sex differences in metabolite titres. In addition, they also showed significant within-sex...
