Data from: The relative importance of green infrastructure as refuge habitat for pollinators increases with local land-use intensity

Pengyao Li, David Kleijn, Isabelle Badenhausser, Carlos Zaragoza-Trello, Nicolas Gross, Ivo Raemakers & Jeroen Scheper
1. Agricultural expansion and intensification have resulted in strong declines in farmland biodiversity across Europe. In many intensively farmed landscapes, linear landscape elements such as field boundaries, road verges and ditch banks are the main remaining green infrastructures providing refuge for biodiversity, and as such play a pivotal role in agri-environmental policies aiming at mitigating biodiversity loss. Yet, while we have a fairly good understanding of how agricultural intensification influences biodiversity on farmland, little is...

In situ resistance, not immigration, supports invertebrate community resilience to drought intensification in a Neotropical ecosystem

Camille Bonhomme, Régis Céréghino, Jean-François Carrias, Arthur Compin, Bruno Corbara, Vincent E.J. Jassey, Joséphine Leflaive, Vinicius F. Farjalla, Nicholas A. C. Marino, Thibaut Rota, Diane S. Srivastava & Céline Leroy
While future climate scenarios predict declines in precipitations in many regions of the world, little is known of the mechanisms underlying community resilience to prolonged dry seasons, especially in “naïve” Neotropical rainforests. Predictions of community resilience to intensifying drought are complicated by the fact that the underlying mechanisms are mediated by species’ tolerance and resistance traits, as well as rescue through dispersal from source patches. We examined the contribution of in situ tolerance-resistance and immigration...

Geographical variation in the trait-based assembly patterns of multitrophic invertebrate communities

Diane S. Srivastava, A. Andrew M. MacDonald, Valério D. Pillar, Pavel Kratina, Vanderlei J. Debastiani, Laura Melissa Guzman, M. Kurtis Trzcinski, Olivier Dézerald, Ignacio M. Barberis, Paula M. De Omena, Gustavo Q. Romero, Fabiola Ospina Bautista, Nicholas A. C. Marino, Céline Leroy, Vinicius F. Farjalla, Barbara A. Richardson, Ana Z. Gonçalves, Bruno Corbara, Jana S. Petermann, Michael J. Richardson, Michael C. Melnychuk, Merlijn Jocqué, Jacqueline T. Ngai, Stanislas Talaga, Gustavo C. O. Piccoli … & Régis Céréghino
It has been argued that the mechanisms structuring ecological communities may be more generalizable when based on traits than on species identities. If so, patterns in the assembly of community-level traits along environmental gradients should be similar in different places in the world. Alternatively, geographic change in the species pool and regional variation in climate might result in site-specific relationships between community traits and local environments. These competing hypotheses are particularly untested for animal communities....

This dataset contains a single whole-genome optical map file (.CMAP) for bread wheat (Triticum aestivum) cv Chinese Spring (CS). The methods for constructing this optical map and the properties of this map are described below. The definition of the CMAP format is documented in https://bionanogenomics.com/wp-content/uploads/2017/03/30039-CMAP-File-Format-Specification-Sheet.pdf. The extracted ultra-high-molecular weight DNA molecules of CS were labeled with the DLE-1 enzyme (Bionano Genomics, San Diego, CA, USA) and were then stained with the Bionano PrepTM DLS Kit...

Supplementary Data - The Paris Biota decapod (Arthropoda) fauna and the diversity of Triassic decapods

Christopher Smith, Charbonnier Sylvain, James Jenks, Kevin Bylund, Gilles Escarguel, Nicolas Olivier, Emmanuel Fara & Arnaud Brayard
We describe here the early Spathian (Early Triassic) Paris Biota decapod fauna from the western USA basin. This fauna contains two taxa of Aegeridae (Dendobranchiata), namely Anisaeger longirostrus n. sp. and Aeger sp. that are the oldest known representatives of their family, thus extending its temporal range by 5 Myr back into the Early Triassic. This fauna also includes two representatives of Glypheida (Pleocyemata) with Litogaster turnbullensis Schram, 1971 and Pemphix krumenackeri n. sp., comforting...

Data from: Persistence at the final stage of volcanic island ontogeny: abiotic predictors explain native plant species richness on 111 remote Pacific atolls

Sebastien Larrue, Jean-François Butaud, Curtis C. Daehler, Stéphane Ballet, Julien Chadeyron & Roger Oyono
Aim: The final island ontogeny of the General Dynamic Model (GDM) (i.e. before island submergence) in tropical oceans corresponds to the coral atoll stage. Here, we examined whether the species richness of native vascular plants (indigenous and endemic species) on atolls is controlled by spatial and/or physical processes. We also predicted that atolls strongly affected by anthropogenic disturbance would have lower native species richness than predicted by spatial and physical processes. Location: Marshall Islands, Kiribati...

Effects of high and low-efficacy therapy in secondary progressive multiple sclerosis

Izanne Roos, Emmanuelle Leray, Romain Casey, Dana Horakova, Eva Havrdova, Guillermo Izquierdo, Sara Eichau, Francesco Patti, Gilles Edan, Marc Debouverie, Jean Pelletier, Serkan Ozakbas, Maria Pia Amato, Pierre Clavelou, Pierre Grammond, Cavit Boz, Katherine Buzzard, Olga Skibina, Jonathan Ciron, Oliver Gerlach, Francois Grand'Maison, Jeannette Lechner-Scott, Charles Malpas, Helmut Butzkueven, Sandra Vukusic … & Tomas Kalincik
Objective: To compare the clinical effectiveness of high- and low-efficacy treatments in patients with recently active and inactive secondary progressive multiple sclerosis (SPMS) after accounting for therapeutic lag. Methods: Patients treated with high- (natalizumab, alemtuzumab, mitoxantrone, ocrelizumab, rituximab, cladribine, fingolimod) or low-efficacy (interferon β, glatiramer acetate, teriflunomide) therapies after SPMS onset were selected from MSBase and OFSEP, two large observational cohorts. Therapeutic lag was estimated for each patient based on their demographic and clinical characteristics....

Sales, Erika R. Manuli, Julien Thézé, Luiz Almeida, Mariane T. Menezes, Carolina M. Voloch, Marcilio J. Fumagalli, Thaís M. Coletti, Camila A. M. Da Silva, Mariana S. Ramundo, Mariene R. Amorim, Henrique H. Hoeltgebaum, Swapnil Mishra, Mandev S. Gill, Luiz M. Carvalho, Lewis F. Buss … & Nuno R. Faria
Brazil currently has one of the fastest growing SARS-CoV-2 epidemics in the world. Owing to limited available data, assessments of the impact of non-pharmaceutical interventions (NPIs) on virus spread remain challenging. Using a mobility-driven transmission model, we show that NPIs reduced the reproduction number from >3 to 1–1.6 in São Paulo and Rio de Janeiro. Sequencing of 427 new genomes and analysis of a geographically representative genomic dataset identified >100 international virus introductions in Brazil....

Data from: Insular woody daisies (Argyranthemum , Asteraceae) are more resistant to drought-induced hydraulic failure than their herbaceous relatives

Larissa C. Doria, Diego S. Podadera, Marcelino Del Arco, Thibaud Chauvin, Erik Smets, Sylvain Delzon & Frederic Lens
1. Insular woodiness refers to the evolutionary transition from herbaceousness towards derived woodiness on (sub)tropical islands, and leads to island floras that have a higher proportion of woody species compared to floras of nearby continents. 2. Several hypotheses have tried to explain insular woodiness since Darwin’s original observations, but experimental evidence why plants became woody on islands is scarce at best. 3. Here, we combine experimental measurements of hydraulic failure in stems (as a proxy...

Data from: The effects of food web structure on ecosystem function exceeds those of precipitation

M. Kurtis Trzcinski, Diane S. Srivastava, Bruno Corbara, Olivier Dézerald, Céline Leroy, Jean-François Carrias, Alain Dejean & Régis Céréghino
Ecosystems are being stressed by climate change, but few studies have tested food web responses to changes in precipitation patterns and the consequences to ecosystem function. Fewer still have considered whether results from one geographic region can be applied to other regions, given the degree of community change over large biogeographic gradients. We assembled, in one field site, three types of macroinvertebrate communities within water-filled bromeliads. Two represented food webs containing both a fast filter...

Data from: Dental status of New Caledonian children: is there a need for a new oral health promotion programme?

Hélène Pichot, Martine Hennequin, Bernard Rouchon, Bruno Pereira & Stéphanie Tubert-Jeannin
Background: Before implementing a new oral health promotion program in the French overseas territory of Nouvelle Calédonie, the health authorities needed recent data about dental status of the New Caledonian child population. Objectives: This study aimed to describe the dental status of 6, 9 and 12-yr-old New Caledonian children and to investigate the environmental and behavioural risk factors related to oral health. Methods: A randomly selected sample of 2734 children (744 6-yr-olds, 789 9-yr-olds, and...

Simulation of sheared granular layers activated by fluid pressurization

Nho Gia Hien Nguyen, Luc Scholtès, Yves Guglielmi, Frédéric Victor Donzé, Zady Ouraga & Mountaka Souley
Fluid pressurization of critically stressed sheared zones can trigger slip mechanisms at play in many geological rupture processes, including earthquakes or landslides. The increasing fluid pressure reduces the effective stress, giving possibility to the shear zone to reactivate. Nonetheless, the mechanisms that dictate the mode of slip, from aseismic steady creep to seismic dynamic rupture, remain poorly understood. By using discrete element modeling, we simulate pore-pressure-step creep test experiments on a sheared granular layer under...
