JSON Implementation of Time-Frequency Radio Catalogues: TFCat

Baptiste Cecconi, Xavier Bonnin & Alan Loh
TFCat (Time-Frequency Catalogue) is a data interchange format based on JSON. It defines several types of JSON objects and the manner in which they are combined to represent data about time-frequency features of a time spectrogram (a.k.a. dynamic spectrum), their properties, and their temporal and spectral extents.

Data from: Contemporary genetic structure and postglacial demographic history of the black scorpionfish, Scorpaena porcus, in the Mediterranean and the Black Seas

Emilie Boissin, Dragos Micu, Marion Janczyszyn-Le Goff, Valentina Neglia, Levent Bat, Valentina Todorova, Marina Panayotova, Claudia Kruschel, Vesna Macic, Nataliya Milchakova, Çetin Keskin, Aikaterini Anastasopoulou, Ina Nasto, Lorenzo Zane & Serge Planes
Understanding the distribution of genetic diversity in the light of past demographic events linked with climatic shifts will help to forecast evolutionary trajectories of ecosystems within the current context of climate change. In this study, mitochondrial sequences and microsatellite loci were analysed using traditional population genetic approaches together with Bayesian dating and the more recent approximate Bayesian computation scenario testing. The genetic structure and demographic history of a commercial fish, the black scorpionfish, Scorpaena porcus,...

Cortical encoding of melodic expectations in human temporal cortex

Giovanni Di Liberto, Claire Pelofi, Roberta Bianco, Prachi Patel, Ashesh D Mehta, Jose L Herrero, Alain De Cheveigné, Shihab A Shamme & Nima Mesgarani
Humans engagement in music rests on underlying elements such as the listeners’ cultural background and interest in music. These factors modulate how listeners anticipate musical events, a process inducing instantaneous neural responses as the music confronts these expectations. Measuring such neural correlates would represent a direct window into high-level brain processing. Here we recorded cortical signals as participants listened to Bach melodies. We assessed the relative contributions of acoustic versus melodic components of the music...

Data from: Analyzing movement behavior and dynamic space-use strategies among habitats using multi-event capture-recapture modeling

Hugo Cayuela, Roger Pradel, Pierre Joly & Aurélien Besnard
1.The environment of most species is heterogeneous at different spatial and temporal scales; this heterogeneity can have a direct effect on various components of fitness. As a consequence, individual space-use and movement strategies are central issues in ecology and conservation and receive considerable attention from researchers. 2.In the last 30 years, this issue has led to the development of capture–recapture models that allow movement between sites to be quantified, while handling imperfect detection. For studies...

Quantifying heritability and estimating evolutionary potential in the wild when individuals that share genes also share environments

Laura Gervais, Nicolas Morellet, Ingrid David, Mark Hewison, Denis Reale, Michel Goulard, Yannick Chaval, Bruno Lourtet, Bruno Cargnelutti, Joel Merlet, Erwan Quéméré & Benoit Pujol
Accurate heritability estimates for fitness-related traits are required to predict an organism’s ability to respond to global change. Heritability estimates are theoretically expected to be inflated if, due to limited dispersal, individuals that share genes are also likely to share similar environments. However, if relatives occupy similar environments due, at least partly, to genetic variation for habitat selection, then accounting for environmental similarity in quantitative genetic models may result in diminished heritability estimates in wild...

Data from: The ecological roots of human susceptibility to social influence: a pre-registered study investigating the impact of early life adversity

Pierre O. Jacquet, Lou Safra, Valentin Wyart, Nicolas Baumard & Coralie Chevallier
There is considerable variability in the degree to which individuals rely on their peers to make decisions. Although theoretical models predict that environmental risks shift the cost-benefit trade-off associated with social information use, this idea has received little empirical support. Here we aim to test the effect of childhood environmental adversity on humans’ susceptibility to follow others’ opinion in the context of a standard face evaluation task. Results collected in a pilot study involving 121...

Data from: Functional biogeography of dietary strategies in birds

Jean-Yves Barnagaud, Nathan Mazet, François Munoz, Matthias Grenié, Pierre Denelle, Mar Sobral, W. Daniel Kissling, Çağan H. Sekercioglu & Cyrille Violle
Aim: Diet is key to understanding species’ resource use, relationships with their environment and biotic interactions. We aimed to identify the major strategies that shape birds’ diet space, and to investigate their spatial distributions in association with biogeographic, bioclimatic and anthropogenic drivers. Location: Global Time period: Current Major taxa studied: Birds Methods: We analysed score-based assessments of eight diet categories for 8937 out of 10964 extant bird species. We constructed a multivariate diet space by...

Data from: Evolution of equal division among unequal partners.

Stéphane Debove, Nicolas Baumard & Jean-Baptiste André
One of the hallmarks of human fairness is its insensitivity to power: while strong individuals are often in a position to coerce weak individuals, fairness requires them to share the benefits of cooperation equally. The existence of such egalitarianism is poorly explained by current evolutionary models. We present a model based on cooperation and partner choice that can account for the emergence of a psychological disposition toward fairness, whatever the balance of power between the...

Data from: Cascading effects of thermally-induced anemone bleaching on associated anemonefish hormonal stress response and reproduction

Ricardo Beldade, Agathe Blandin, Rory O'Donnell & Suzanne C. Mills
Organisms can behaviorally, physiologically, and morphologically adjust to environmental variation via integrative hormonal mechanisms, ultimately allowing animals to cope with environmental change. The stress response to environmental and social changes commonly promotes survival at the expense of reproduction. However, despite climate change impacts on population declines and diversity loss, few studies have attributed hormonal stress responses, or their regulatory effects, to climate change in the wild. Here, we report hormonal and fitness responses of individual...

Investigating population dynamics from parentage analysis in the highly endangered fan mussel Pinna nobilis

Claire Peyran, Emilie Boissin, Titouan Morage, Elisabet Nebot-Colomer, Guillaume Iwankow & Serge Planes
Understanding dispersal patterns is a major focus for conservation biology as it influences local survival and resilience in case of local disturbance, particularly for sessile species. Dispersal can be assessed through parentage analyses by estimating family structure and self-recruitment. This study documents the family structure of a pelagic spawner, Pinna nobilis, which is facing a major crisis that threatens its survival as most of its populations have been decimated by a parasite, Haplosporidium pinnae. In...

Pedigree-free quantitative genetic approach provides evidence for heritability of movement tactics in wild roe deer

Laura Gervais, Aidan.J Mark Hewison, Nicolas Morellet, Maria Bernard, Joël Merlet, Bruno Cargnelutti, Yannick Chaval, Benoit Pujol & Erwan QUEMERE
Assessing the evolutionary potential of animal populations in the wild is crucial to understanding how they may respond to selection mediated by rapid environmental change (e.g. habitat loss and fragmentation). A growing number of studies have investigated the adaptive role of behaviour, but assessments of its genetic basis in a natural setting remain scarce. We combined intensive biologging technology with genome-wide data and a pedigree-free quantitative genetic approach to quantify repeatability, heritability and evolvability for...

Data from: Partner choice creates fairness in humans

Stéphane Debove, Jean-Baptiste André, Nicolas Baumard & J.-B. Andre
Many studies demonstrate that partner choice has played an important role in the evolution of human cooperation, but little work has tested its impact on the evolution of human fairness. In experiments involving divisions of money, people become either over-generous or over-selfish when they are in competition to be chosen as cooperative partners. Hence, it is difficult to see how partner choice could result in the evolution of fair, equal divisions. Here, we show that...

Data from: Harnessing olfactory bulb oscillations to perform fully brain-based sleep-scoring and real-time monitoring of anesthesia depth

Sophie Bagur, Marie M. Lacroix, Gaëtan De Lavilléon, Julie M. Lefort, Hélène Geoffroy & Karim Benchenane
Real-time tracking of vigilance states related to both sleep or anaesthesia has been a goal for over a century. However, sleep scoring cannot currently be performed with brain signals alone, despite the deep neuromodulatory transformations that accompany sleep state changes. Therefore, at heart, the operational distinction between sleep and wake is that of immobility and movement, despite numerous situations in which this one-to-one mapping fails. Here we demonstrate, using local field potential (LFP) recordings in...

Data from: One-locus-several-primers: a strategy to improve the taxonomic and haplotypic coverage in diet metabarcoding studies

Emmanuel Corse, Christelle Tougard, Gaït Archambaud-Suard, Jean-François Agnèse, Françoise D. Messu Mandeng, Charles F. Bilong Bilong, David Duneau, Lucie Zinger, Rémi Chappaz, Charles C. Y. Xu, Emese Meglécz & Vincent Dubut
In diet metabarcoding analyses, insufficient taxonomic coverage of PCR primer sets generates false negatives that may dramatically distort biodiversity estimates. In this paper, we investigated the taxonomic coverage and complementarity of three cytochrome c oxidase subunit I gene (COI) primer sets based on in silico analyses and we conducted an in vivo evaluation using fecal and spider web samples from different invertivores, environments, and geographic locations. Our results underline the lack of predictability of both...

Data from: Visual system development of the spotted unicornfish, Naso brevirostris (Acanthuridae)

Valerio Tettamanti, Fanny De Busserolles, David Lecchini, N. Justin Marshall & Fabio Cortesi
Ontogenetic changes of the visual system are often correlated to shifts in habitat and feeding behaviour of animals. Coral reef fishes begin their lives in the pelagic zone and then migrate to the reef. This habitat transition frequently involves a change in diet and light environment as well as major morphological modifications. The spotted unicornfish, Naso brevirostris, is known to shift diet from zooplankton to algae and back to mainly zooplankton when transitioning from larval...

Drivers of amphibian population dynamics and asynchrony at local and regional scales

Hugo Cayuela, Richard A. Griffiths, Nurul Zakaria, Jan W. Arntzen, Pauline Priol, Jean-Paul Léna, Aurélien Besnard & Pierre Joly
Identifying the drivers of population fluctuations in spatially distinct populations remains a significant challenge for ecologists. Whereas regional climatic factors may generate population synchrony (i.e., the Moran effect), local factors including the level of density-dependence may reduce the level of synchrony. Although divergences in the scaling of population synchrony and spatial environmental variation have been observed, the regulatory factors that underlie such mismatches are poorly understood. Few previous studies have investigated how density-dependent processes and...

DNA metabarcoding marker choice skews perception of marine eukaryotic biodiversity

Jordan M Casey, Emma Ransome, Allen G Collins, Angka Mahardini, Eka M Kurniasih, Andrianus Sembiring, Nina M D Schiettekatte, Ni Kadek Dita Cahyani, Aji Wahyu Anggoro, Mikaela Moore, Abby Uehling, Mahdi Belcaid, Paul H Barber, Jonathan B Geller & Christopher P Meyer
DNA metabarcoding is an increasingly popular technique to investigate biodiversity; however, many methodological unknowns remain, especially concerning the biases resulting from marker choice. Regions of the cytochrome c oxidase subunit I (COI) and 18S rDNA (18S) genes are commonly employed “universal” markers for eukaryotes, but the extent of taxonomic biases introduced by these markers and how such biases may impact metabarcoding performance is not well quantified. Here, focusing on macro-eukaryotes, we use standardized sampling from...

Data for Vijendravarma et al 2022: Drosophila females have an acoustic preference for symmetric males.

Roshan Kumar Vijendravarma, Sunitha Narasimha, Elsa Steinfath, Jan Clemens & Pierre Leopold
In many species, including humans and Drosophila, symmetric individuals secure more mating’s, suggesting that bilateral symmetry signals quality of potential mates and is subjected to sexual selection. However, this idea remains controversial, largely because obtaining conclusive experimental evidence has been hindered by confounding effects arising from methods used to increase asymmetry in test subjects. Here, we show that altering gravity during development increases asymmetry in Drosophila melanogaster without detrimental effect on survival, growth and behaviour....

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...
