Data from: Effects of a systematically offered social and preventive medicine consultation on training and health attitudes of young people not in employment, education or training (NEETs): an interventional study in France

Sarah Robert, Lucile Romanello, Sophie Lesieur, Virginie Kergoat, Joel Dutertre, Gladys Ibanez & Pierre Chauvin
Background NEETs (young people not in employment, education or training) are at higher risk for poorer mental and physical health. In France, the Missions locales (MLs) are the only social structures dedicated to this population. We sought to determine whether the systematic offer of a social and preventive medicine consultation at a ML might increase NEET participants’ access to training in the 12 months following the intervention. Methods This intervention research was a parallel randomised...

Herlon Nadolny, Alessandra Santos, Wilian Demetrio, Talita Ferreira, Lilianne Dos Santos Maia, Ana Caroline Conrado, Marie Bartz, Marilice Garrastazu, Elodie Da Silva, Dilmar Baretta, Amarildo Pasini, Fabiane Vezzani, José Paulo Sousa, Luis Cunha, Jerome Mathieu, Patrick Lavelle, Jörg Römbke & George Brown
Earthworms are often related to fertile soils and frequently used as environmental quality indicators. However, to optimize their use as bioindicators, their populations must be evaluated together with environmental and anthropogenic variables regulating earthworm communities. In this review we identify the earthworm, soil chemical, physical, environmental and management-related variables evaluated in 124 published studies that quantified earthworm abundance (>7300 samples) in 765 sites with different types of climate, soils, land use and management systems in...

Data from: Determinants of tree cover in tropical floodplains

Joshua H. Daskin, Filipe Aires & A. Carla Staver
In uplands, water availability and fire limit tree cover, differentiating between tropical forest, savanna, and grassland biomes. In contrast, we know less about tropical floodplain tree cover determinants, although these habitats similarly include near-treeless grasslands, moderately treed savannas, and forests. Using GIS and remotely sensed data from 13 large tropical and sub-tropical floodplain ecosystems on five continents, we show that floodplain tree cover increases with climatic water balance (= rainfall - potential evapotranspiration) and decreases...

From individuals to populations: How intraspecific competition shapes thermal reaction norms

Thomas Tully, François Mallard, Vincent Le Bourlot, Christie Le Coeur, Monique Avnaim, Romain Peronnet & David Claessen
1. Most ectotherms follow the temperature-size rule (TSR): in cold environments individuals grow slowly but reach a large asymptotic length. Intraspecific competition can induce plastic changes of growth rate and asymptotic length and competition may itself be modulated by temperature. 2. Our aim is to disentangle the joint effects of temperature and intraspecific competition on growth rate and asymptotic length. 3. We used two distinct clonal lineages of the Collembola Folsomia candida, to describe thermal...

Data from: A strong east–west Mediterranean divergence supports a new phylogeographic history of the carob tree (Ceratonia siliqua, Leguminosae) and multiple domestications from native populations

Juan Viruel, Nicolas Le Galliot, Samuel Pironon, Jean Pierre Suc, Gonzalo Nieto Feliner, Fatma Lakhal-Mirleau, Marianick Juin, Marjorie Selva, Magda Bou Dagher-Kharrat, Lahcen Ouahmane, Stefano La Malfa, Katia Diadema, Hervé Sanguin, Frédéric Médail & Alex Baumel
Aim: Phylogeography of fruit trees is challenging due to the recurrent exchanges between domesticated and wild populations. Here we tested the eastern refugium hypothesis (ERH) for the carob tree, Ceratonia siliqua, which supports its natural and domestication origins in the Eastern Mediterranean and a feral origin in the West. Location: Mediterranean basin Taxon: Ceratonia siliqua L., Leguminosae Methods: Divergence time of the divergence between the carob tree and its sister species (C. oreothauma) was estimated...

Data from: Pooled analysis suggests benefit of catheter-based hematoma removal for intracerebral hemorrhage

Pitchaiah Mandava, Santosh B. Murthy, Neel Shah, Yves Samson, Marek Kimmel & Thomas A. Kent
Objective: To develop models of outcome for intracerebral hemorrhage (ICH) to identify promising and futile interventions based on their early phase results without need for correction for baseline imbalances. Methods: We developed a pooled outcome model from the control arms of randomized control trials and tested different interventions against the model at comparable baseline conditions. Eligible clinical trials and large case series were identified from multiple library databases. Models based on baseline factors reported in...

Data from: Beyond dispersal versus philopatry? Alternative behavioural tactics of juvenile roe deer in a heterogeneous landscape

Delphine Ducros, Nicolas Morellet, Rémi Patin, Kamal Atmeh, Lucie Debeffe, Bruno Cargnelutti, Yannick Chaval, Bruno Lourtet, Aurélie Coulon & A. J. Mark Hewison
Although inter-individual heterogeneity in many aspects of dispersal behaviour is widely reported, this key life-history trait is predominantly modelled as a dichotomous state of philopatry vs. dispersal. The increasing body of evidence for dispersal syndromes (i.e. a suite of correlated morphological, behavioural, and life-history traits associated with dispersal) implies substantial but, to date, undocumented individual heterogeneity in behavioural tactics during dispersal. Using a large sample (N = 154) of GPS monitored juvenile roe deer (Capreolus...

Data from: Transparency improves concealement in cryptically coloured moths

Mónica Arias, Marianne Elias, Christine Andraud, Serge Berthier & Doris Gomez
Predation is a ubiquitous and strong selective pressure on living organisms. Transparency is a predation defence widespread in water but rare on land. Some Lepidoptera display transparent patches combined with already cryptic opaque patches. A recent study showed that transparency reduced detectability of aposematic prey with conspicuous patches. However, whether transparency has any effect at reducing detectability of already cryptic prey is still unknown. We conducted field predation experiments with free avian predators where we...

Data from: Developmental constraints and resource environment shape early emergence and investment in spines in saplings

Mohammed Armani, Tristan Charles-Dominique, Kasey E. Barton & Kyle W. Tomlinson
Abstract Background and Aims Herbivory by large mammals imposes a critical recruitment bottleneck on plants in many systems. Spines defend plants against large herbivores and how early they emerge in saplings may be one of the strongest predictors of sapling survival in herbivore-rich environments. Yet little effort has been directed at understanding the variability in spine emergence across saplings. Methods We present a multi-species study examining whether and how sapling size,spine type and species’ environmental...

Data from: Exceptional preservation requires fast biodegradation: thylacocephalan specimens from La Voulte‐sur‐Rhône (Callovian, Jurassic, France)

Clément Jauvion, Sylvain Bernard, Pierre Gueriau, Cristian Mocuta, Sylvain Pont, Karim Benzerara & Sylvain Charbonnier
Konservat-Lagerstätten are seen as snapshots of past biodiversity for a given location and time. Yet, processes leading to the exceptional morphological preservation of fossils in these deposits remain incompletely understood. This results in the deficient assessment of taphonomic biases and limits the robustness/relevance of palaeobiological reconstructions. Here, we report the mineralogical characterization of crustacean fossils preserved within carbonate-rich concretions from the Jurassic Konservat-Lagerstätte of La Voulte-sur-Rhône (Ardèche, France). The combination of SEM-EDS, TEM, synchrotron-based XRF,...

Data from: Enigmatic hook-like structures in Mesozoic ammonites (Scaphitidae)

Isabelle Kruta, Jeremie Bardin, Christopher Smith, Paul Tafforeau & Neil Landman
In the last few decades, hook-like structures have been reported in the Mesozoic ammonite family Scaphitidae. Despite their exceptional preservation and debates about their function, no detailed reconstruction of them has yet been made. For the first time, we describe the composition and detailed morphology of these structures in the body chambers of six specimens of the Campanian ammonite Rhaeboceras halli (Meek and Hayden) using high resolution X-ray imaging. The hook-like structures are composed of...

Data from: A genome-wide investigation of the worldwide invader Sargassum muticum shows high success albeit (almost) no genetic diversity

Sabrina Le Cam, Claire Daguin-Thiébaut, Sarah Bouchemousse, Aschwin Engelen, Nova Mieszkowska & Frédérique Viard
Twenty-years of genetic studies of marine invaders have shown that successful invaders are often characterized by native and introduced populations displaying similar levels of genetic diversity. This pattern is presumably due to high propagule pressure and repeated introductions. The opposite pattern is reported in this study of the brown seaweed, Sargassum muticum, an emblematic species for circumglobal invasions. Albeit demonstrating polymorphism in the native range, microsatellites failed to detect any genetic variation over 1269 individuals...

Data from: Bone histology of Azendohsaurus laaroussii. Implications for the evolution of thermometabolism in Archosauromorpha

Jorge Cubo & Nour-Eddine Jalil
This paper is aimed at constraining the phylogenetic frame of the acquisition of endothermy by Archosauromorpha. We analyzed the bone histology of Azendohsaurus laaroussii. Stylopodial and zeugopodial bones show three tissue types: (a) avascular lamellar zonal bone formed at low growth rates; (b) a scaffold of parallel fibered bone containing either small primary osteons or simple vascular canals; and (c) fibrolamellar bone formed at high growth rates. We used quantitative histology to infer the thermometabolic...
