Data from: Ups and downs of belemnite diversity in the Early Jurassic of Western Tethys

Pascal Neige, Pascal Neige, Robert Weis & Emmanuel Fara
Although belemnites form a major clade of extinct cephalopods, the early stage of their diversification remains poorly known in time and space. Here we investigate the first diversification episodes of belemnites (order Belemnitida) using a new species-level database encompassing the Hettangian-Aalenian interval (Early Jurassic-earliest Middle Jurassic) and covering the Western Tethys. Rarefied richness shows a four-fold increase from the Planorbis chronozone to the Ibex chronozone, a strong decrease between the Margaritatus and Spinatum chronozones, followed...

La fabrique de l'information sportive : L'Auto (1900-1944)

Launched in October 1900, it quickly gained a dominant position in the sports news market, which it held until its demise in August 1944. Its print run made it one of the leading national newspapers. It is renowned for the quality of the information it delivers to its readers day after day, information for which it often has the first...

Data from: Trepostomate bryozoans from the upper Katian (Upper Ordovician) of Morocco: gigantism in high latitude Gondwana platforms

Andrea Jiménez-Sánchez, Enmanuelle Vennin & Enrique Villas
A study of the Upper Ordovician trepostomate bryozoans belonging to the families Amplexoporidae and Monticuliporidae, from the eastern Anti-Atlas of Morocco, is presented here. They occur in the marly to fine-grained limestone, intermediate unit of the Khabt-el-Hajar Formation, late Katian in age, representing outer-ramp depositional environments. They inhabited the highest paleolatitude known for a bryozoan fauna during the Ordovician, estimated at more than 65–70ºS. A total of 11 species of the genera Anaphragma, Atactoporella, Homotrypa,...

Immunological indices and parasites in blackbirds

Jérôme Moreau
1. Despite the intensive use of immune indices in immunoecology, whether to interpret the results of immune indices in terms of actual immune competence (i.e., ability to control and clear parasite infections as indicated by high values of immune indices associated with low parasite loads) or current immune activation (pathogenic infection being associated with high parasite load and high values of immune indices) is still an open question. Most studies to date have produced contrasting...

Enforced monoandry and female investment into reproduction

Gabriele Sorci, Loïc Lesobre, Pauline Vuarin, Gwènaëlle Levêque, Michel Saint Jalme & Frédéric Lacroix
While uncovering the costs and benefits of polyandry has attracted considerable attention, assessing the net effect of sexual selection on population fitness requires the experimental manipulation of female mating over generations, which is usually only achievable in laboratory populations of arthropods. However, knowing if sexual selection improves or impairs the expression of life history traits is key for the management of captive populations of endangered species, which are mostly long-lived birds and mammals. It might...

Hudson, Kelly Inward, David T. Jones, Agnieszka Kosewska, Nancy F. Lo-Man-Hung, Tibor Magura, Christian Mulder, Maka Murvanidze, Tim Newbold, Jo Smith, Andrew V. Suarez, Sasha Suryometaram, Béla Tóthmérész, Marcio Uehara-Prado … & Andy Purvis
Abstract Background Land-use is a major driver of changes in biodiversity worldwide, but studies have overwhelmingly focused on above-ground taxa: the effects on soil biodiversity are less well known, despite the importance of soil organisms in ecosystem functioning. We modelled data from a global biodiversity database to compare how the abundance of soil-dwelling and above-ground organisms responded to land use and soil properties. Results We found that land use affects overall abundance differently in soil...

Muhammad Kohailan, Waleed Aamer, Najeeb Syed, Sujitha Padmajeya, Sura Hussein, Amira Sayed, Jyothi Janardhanan, Sasirekha Palaniswamy, Nady El hajj, Ammira Al-Shabeeb Akil & Khalid A. Fakhro
While de novo mutations (DNMs) are key to genetic diversity, they are also responsible for a high number of rare disorders. To date, no study has systematically examined the rate and distribution of DNMs in multiplex families in highly consanguineous populations. Leveraging WGS profiles of 645 individuals in 146 families, we implemented a combinatorial approach using 3 complementary tools for DNM discovery in 353 unique trio combinations. We found a total of 27,168 DNMs (median:...

Data from: Recovery of benthic marine communities from the end-Permian mass extinction at the low-latitudes of Eastern Panthalassa

Richard Hofmann, Michael Hautmann, Arnaud Brayard, Alexander Nützel, Kevin Bylund, James Jenks, Emmanuelle Vennin, Nicolas Olivier & Hugo Bucher
Based on the quantitative community analysis using species-level identifications, we track the restoration of benthic ecosystems after the end-Permian mass extinction throughout the Lower Triassic of the western USA. New data on the palaeoecology of the Thaynes Group and Sinbad Formation are provided, which fill a gap between the recently studied palaeoecology of the Griesbachian–Dienerian Dinwoody Formation and the Spathian Virgin Formation. In the Sinbad Formation and Thaynes Group, 17 species (12 genera) of bivalves,...

Data from: Pairing context determines condition-dependence of song rate in a monogamous passerine bird

Morgan David, Yannick Auclair, Sasha R. X. Dall & Frank Cézilly
Condition-dependence of male ornaments is thought to provide honest signals on which females can base their sexual choice for genetic quality. Recent studies show that condition-dependence patterns can vary within populations. Although long-term association is thought to promote honest signalling, no study has explored the influence of pairing context on the condition-dependence of male ornaments. In this study, we assessed the influence of natural variation in body condition on song rate in zebra finches (Taeniopygia...

Data from: The legacy of a vanished sea: a high level of diversification within a European freshwater amphipod species complex driven by 15 My of Paratethys regression

Tomasz Mamos, Remi Wattier, Artur Burzyński & Michał Grabowski
The formation of continental Europe in the Neogene was due to the regression of the Tethys Ocean and of the Paratethys Sea. The dynamic geology of the area and repetitious transitions between marine and freshwater conditions presented opportunities for the colonization of newly emerging hydrological networks and diversification of aquatic biota. Implementing mitochondrial and nuclear markers in conjunction with a large-scale sampling strategy, we investigated the impact of this spatiotemporal framework on the evolutionary history...

Data on paternal age and sperm production of the progeny

Gabriele Sorci, Pauline Vuarin, Loïc Lesobre, Gwènaëlle Levêque, Michel Saint Jalme, Frédéric Lacroix & Yves Hingrat
Parental age has profound consequences for offspring’s phenotype. However, whether patrilineal age affects offspring sperm production is unknown, despite the importance of sperm production for male reproductive success in species facing post-copulatory sexual selection. Using a longitudinal dataset on ejaculate attributes of the houbara bustard, we showed that offspring sired by old fathers had different age-dependent trajectories of sperm production compared to offspring sired by young fathers. Specifically, they produced less sperm (-48%) in their...

Data from: The cranium of Proviverra typica (Mammalia, Hyaenodonta) and its impact on hyaenodont phylogeny and endocranial evolution

Morgane Dubied, Floréal Solé & Bastien Mennecart
We describe the first endocast reconstruction of a hyaenodont mammal based on X‐ray microtomography. The endocast belongs to the type material of the European hyaenodont Proviverra typica. We performed phylogenetic analysis to contextualize the evolution of endocranial size and complexity in Hyaenodonta. We added several European hyaenodonts and modified several codings of the most recent character–taxon matrix established to question the relationships within Hyaenodonta. Including these new species in a phylogenetic analysis reveals a new...

Data from: Trans-generational immune priming protects the eggs only against gram-positive bacteria in the mealworm beetle

Aurore Dubuffet, Caroline Zanchi, Gwendoline Boutet, Jérôme Moreau, Yannick Moret & Maria Teixeira
In many vertebrates and invertebrates, offspring whose mothers have been exposed to pathogens can exhibit increased levels of immune activity and/or increased survival to infection. Such phenomena, called “Trans-generational immune priming” (TGIP) are expected to provide immune protection to the offspring. As the offspring and their mother may share the same environment, and consequently similar microbial threats, we expect the immune molecules present in the progeny to be specific to the microbes that immune challenged...

Terrestrial palaeo-environmental proxy data of the Upper Pliensbachian, Mochras Borehole sediments, deposited in the Cardigan Bay Basin, Wales

Teuntje Hollaar
Terrestrial palaeo-environmental proxy data has been collected to examine orbital changes in wildfire activity in the Early Jurassic of the Mochras Borehole, Cardigan Bay Basin, Wales. To do this a high resolution charcoal abundance dataset was created and quantified in two size fractions, microscopic charcoal (10-125 µ) and macroscopic charcoal (>125 µ). To take potential changes in riverine influx and/or organic preservation in account on the charcoal abundance, palynofacies were analysed to document all terrestrial...

Searching for genetic evidence of demographic decline in an arctic seabird: beware of overlapping generations

Emeline Charbonnel, Claire Daguin, Lucille Caradec, Eléonore Moittié, Olivier Gilg, Maria Gavrilo, Hallvard Strom, Mark L Mallory, Grant Gilchrist, R. I. Guy Morrisson, Raphael Leblois, Camille Roux, Jonathan M Yearsley, Glenn Yannic & Thomas Broquet
Genetic data are useful for detecting sudden population declines in species that are difficult to study in the field. Yet this indirect approach has its own drawbacks, including population structure, mutation patterns, and generation overlap. The ivory gull (Pagophila eburnea), a long-lived Arctic seabird, is currently suffering from rapid alteration of its primary habitat (i.e., sea ice), and dramatic climatic events affecting reproduction and recruitment. However, ivory gulls live in remote areas, and it is...

Outcomes of mild-to-moderate postresuscitation shock after non-shockable cardiac arrest and association with temperature management: a post hoc analysis of HYPERION trial data

Ines Ziriat, Aurélie Le Thuaut, Gwenhael Colin, Hamid Merdji, Guillaume Grillet, Patrick Girardie, Bertrand Souweine, Pierre-François Dequin, Thierry Boulain, Jean-Pierre Frat, Pierre Asfar, Bruno Francois, Mickael Landais, Gaëtan Plantefeve, Jean-Pierre Quenot, Jean-Charles Chakarian, Michel Sirodot, Stéphane Legriel, Nicolas Massart, Didier Thevenin, Arnaud Desachy, Arnaud Delahaye, Vlad Botoc, Sylvie Vimeux, Frederic Martino … & Jean Baptiste Lascarrou
Abstract Background Outcomes of postresuscitation shock after cardiac arrest can be affected by targeted temperature management (TTM). A post hoc analysis of the “TTM1 trial” suggested higher mortality with hypothermia at 33 °C. We performed a post hoc analysis of HYPERION trial data to assess potential associations linking postresuscitation shock after non-shockable cardiac arrest to hypothermia at 33 °C on favourable functional outcome. Methods We divided the patients into groups with vs. without postresuscitation (defined...

Doppler study of portal vein and renal venous velocity predict the appropriate fluid response to diuretic in ICU: a prospective observational echocardiographic evaluation

Pierre-Grégoire Guinot, Pierre-Alain Bahr, Stefan Andrei, Bogdan A. Popescu, Vincenza Caruso, Paul-Michel Mertes, Vivien Berthoud, Maxime Nguyen & Belaid Bouhemad
Abstract Background Fluid overload and venous congestion are associated with morbi-mortality in the ICU (intensive care unit). Administration of diuretics to correct the fluid balance is common, although there is no strong relationship between the consequent fluid loss and clinical improvement. The aim of the study was to evaluate the ability of the portal pulsatility index, the renal venous impedance index, and the VEXUS score (venous ultrasound congestion score) to predict appropriate diuretic-induced fluid depletion....

Agroecological farming, flowering phenology and the pollinator-herbivore-parasitoid nexus regulate non-crop plant reproduction

Lucie Monticelli, Audrey Labonté, Mélinda Turpin, Luc Biju-Duval, Emeline Felten, Emilien Laurent, Annick Matejicek, Eric Vieren, Violaine Deytieux, Stéphane Cordeau & Adam Vanbergen
Agroecological farming uses crop and non-crop plant biodiversity to promote beneficial insects supplying pollination and biocontrol services to crops. Non-crop plants (sown or weeds) are integral to supporting these beneficial insect species interactions. How the uplift of biotic complexity by agroecological management (crop diversification, ecological infrastructure) influences mutualistic and antagonistic insect interactions regulating the reproduction of non-crop plants remains less understood. Using a pesticide-free farm-scale (125 ha) agroecological experiment, we tested how the individual reproduction...
