African elephants can detect water from natural and artificial sources via olfactory cues

Matthew Wood, Simon Chamaillé-Jammes, Almuth Hammerbacher & Adrian Shrader
Water is vital for mammals. Yet, as ephemeral sources can be difficult to find, it raises the question, how do mammals locate water? Elephants (Loxodonta africana) are water-dependent herbivores that possess exceptional olfactory capabilities, and it has been suggested that they may locate water via smell. However, there is no evidence to support this claim. To explore this, we performed two olfactory choice experiments with semi-tame elephants. In the first, we tested whether elephants could...

Moorea Biocode

Neil Davies
The core goal of the Moorea Biocode Project (MBP) is to genetically barcode every non-microbial species on Moorea. We will thus create a professionally produced, verifiable (vouchered) All Taxa Biotic Inventory (ATBI) of Moorea (Output 1), together with the informatics services needed for ATBI and biocode-enabled research in Model Ecosystems (Outcome 2). We will also design a long-term plan (business model) to ensure the financial self-sustainability of biocode services, and carry out proof of concept...

Des mammouths sous l’autoroute. L’exploitation des données environnementales et leurs apports pour diagnostiquer et étudier les sites paléolithiques : l’exemple des fouilles du contournement Ouest de Strasbourg (Bas-Rhin)

Sylvain Griselin, François Bachellerie, Olivier Moine, Nathalie Schneider, Patrice Wuscher, Noémie Sévêque, Charlotte Leduc, Héloïse Koehler & Éric Boës
Bien que l’Alsace soit connue pour son potentiel archéologique paléolithique depuis le XIXe siècle, ce n’est que récemment que la recherche en Préhistoire ancienne connaît un nouvel élan. À l’occasion des diagnostics archéologiques menés préalablement au projet autoroutier du Contournement Ouest de Strasbourg, des sondages profonds ont été réalisés. Sept indices de site du Paléolithique moyen ont été identifiés, dont trois ont fait l’objet de fouilles. Les travaux menés sur les séquences lœssiques observées sur...

Behavioral interactions between bacterivorous nematodes and predatory bacteria in a synthetic community

Nicola Mayrhofer, Gregory J. Velicer, Kaitlin A. Schaal & Marie Vasse
Theory and empirical studies in metazoans predict that apex predators should shape the behavior and ecology of mesopredators and prey at lower trophic levels. Despite the ecological importance of microbial communities, few studies of predatory microbes examine such behavioral responses and the multiplicity of trophic interactions. Here, we sought to assemble a three-level microbial food chain and to test for behavioral interactions between the predatory nematode Caenorhabditis elegans and the predatory social bacterium Myxococcus xanthus...

Agroecosystem diversification with legumes or non-legumes improves differently soil fertility according to soil type

Marie Sauvadet, Jean Trap, Gaëlle Damour, Claude Plassard, Karel Van Den Meersche, Raphaël Achard, Clémentine Allinne, Patrice Autfray, Isabelle Bertrand, Eric Blanchart, Péninna Deberdt, Séguy Enock, Jean-Daniel Essobo, Grégoire Freschet, Mickaël Hedde, Elias De Melo Virginio Filho, Bodovololona Rabary, Miora Rakotoarivelo, Richard Randriamanantsoa, Béatrice Rhino, Aude Ripoche, Elisabeth Rosalie, Stéphane Saj, Thierry Becquer, Philippe Tixier … & Jean-Michel Harmand
Plant diversification through crop rotation or agroforestry is a promising way to improve sustainability of agroecosystems. Nonetheless, criteria to select the most suitable plant communities for agroecosystems diversification facing contrasting environmental constraints need to be refined. Here, we compared the impacts of 24 different plant communities on soil fertility across six tropical agroecosystems: either on highly weathered Ferralsols, with strong P limitation, or on partially weathered soils derived from volcanic material, with major N limitation....

Dataset and script to: Morphometric variance, evolutionary constraints and their change through time in Late Devonian Palmatolepis conodonts

Sabrina Renaud, Catherine Girard & Anne-Béatrice Dufour
Phenotypic variation is the raw material of evolution. Standing variation can facilitate response to selection along “lines of least evolutionary resistance”, but selection itself might alter the structure of the variance. Shape was quantified using 2D geometric morphometrics in Palmatolepis conodonts through the Late Devonian period. Patterns of variance were characterized along the record by the variance-covariance matrix (P-matrix) and its first axis (Pmax). The Late Frasnian was marked by environmental oscillations culminating with the...

IASI Atmospheric Temperature Profiles (ATP)

Marie Bouillon
The IASI atmospheric temperature profiles product (IASI ATP) is a daily 1°x1° global dataset of atmospheric temperatures derived from all IASI radiance observations. The temperatures profiles are given on 11 static pressure levels from 750 to 2 hPa. The method used to retrieve atmospheric temperatures from IASI radiances is detailed in Bouillon et al., 2021 (to be submitted very soon). It relies on an Artificial Neural Network (ANN) trained with 450 000 observations (IASI observations...

Data for: Hierarchial motor adaptations negotiate failures during force field learning

Tsuyoshi Ikegami, Gowrishankar Ganesh, Tricia Gibo, Toshinori Yoshioka, Rieko Osu & Mitsuo Kawato
Humans have the amazing ability to learn the dynamics of the body and environment to develop motor skills. Traditional motor studies using arm reaching paradigms have viewed this ability as the process of ‘internal model adaptation’. However, the behaviors have not been fully explored in the case when reaches fail to attain the intended target. Here we examined human reaching under two force fields types; one that induces failures (i.e., target errors), and the other...

IASI-FT spectrally resolved Outgoing Longwave Radiation (from IASI/Metop-A)

simon whitburn
The IASI spectrally resolved Outgoing Longwave Radiation product (IASI OLR) is a monthly (L3), 2 x 2 degree global dataset of spectral OLR derived from the clear-sky IASI satellite radiance measurements in the range 645-2300 cm-1 at the 0.25 cm-1 native spectral sampling of the L1C spectra. The algorithm for the conversion of the spectra to the OLR is detailed in Whitburn et al. (2020, Journal of Climate). It relies on precalculated angular distribution models...

Data from: Impact of male trait exaggeration on sex-biased gene expression and genome architecture in a water strider

Abderrahman Khila, William Toubiana, David Armisen, Corentin Dechaud & Roberto Arbore
Background: Exaggerated secondary sexual traits are widespread in nature and often evolve under strong directional sexual selection. Although heavily studied from both theoretical and empirical viewpoints, we have little understanding of how sexual selection influences sex-biased gene regulation during the development of exaggerated secondary sexual phenotypes, and how these changes are reflected in genomic architecture. This is primarily due to the limited availability of representative genomes and associated tissue- and sex-transcriptomes to study the development...

Disturbance and the (surprising?) role of ecosystem engineering in explaining spatial patterns of non-native plant establishment

Meredith Root-Bernstein, Cesar Muñoz & Juan Armesto
The Intermediate Disturbance Hypothesis is widely considered to be wrong but is rarely tested against alternative hypotheses. It predicts that soil disturbances and herbivory have identical impacts on species richness via identical mechanisms (reduction in biomass and in competition). An alternative hypothesis is that the specific traits of disturbance agents (small mammals) and plants differentially affects richness or abundance of different plant groups. We tested these hypotheses on a degu (Octodon degus) colony in central...

Assessing the effects of artificial light at night on biodiversity across latitude – Current knowledge gaps

Jean Secondi, Aurélie Davranche, Marc Théry, Nathalie Mondy & Thierry Lengagne
Aim: Exposure to artificial light at night (ALAN) is a risk factor for organisms. Considering the spread and increasing intensity of night brightness across the globe, and the key role of light at all biological levels, alterations of ecosystems are expected. Yet, we cannot predict the severity of the effects of ALAN in several biomes because little information is available outside the temperate zone. We reviewed current knowledge and identified traits that could be targeted...

Ils correspondent à des formes de résistance et de dissémination issus des cinq règnes du vivant. Associés à l’analyse des grains de pollen et des spores de végétaux, les premiers résultats obtenus sur les sites de Villeneuve-sur-Lot et de Lavau démontrent leur intérêt tant les informations qu’ils peuvent apporter sont nombreuses sur...

Contribution de la paléogénétique à l’archéologie

Eva-Maria Geigl
La paléogénétique, c’est-à-dire l’analyse génétique de l’ADN préservé dans les vestiges biologiques du passé, principalement os et dents, a ouvert de nouvelles perspectives en archéologie. Cette alliée de poids apporte des informations qui ne sont pas accessibles par d’autres approches et contribue à une meilleure compréhension des sites archéologiques et des sociétés du passé, concernant entre autres migrations et métissages, domestication des animaux et des plantes, effets de l’action humaine sur les populations animales et...

Diversity of biosynthetic gene clusters in gut bacteria of turtle ants

Christophe Duplais
In insect-microbe nutritional symbioses the gut symbionts supplement the host diet with nutrients by producing amino acids and vitamins or by degrading lignin or polysaccharides macromolecules. In multipartite mutualisms composed of multiple symbionts from different taxonomical orders, it has been suggested that beside the genes involved in the nutritional symbiosis the symbionts maintain genes responsible for the production of metabolites putatively playing a role in the maintenance and interaction of the bacterial communities living in...

Supplementary 1: Underwater photogrammetry for close-range 3D imaging of dry-sensitive objects: The case study of cephalopod beaks

Marjorie Roscian, Anthony Herrel, Raphaël Cornette, Arnaud Delapré, Yves Cherel & Isabelle Rouget
Technical advances in 3D imaging have contributed to quantifying and understanding biological variability and complexity. However, small, dry-sensitive objects are not easy to reconstruct using common and easily available techniques such as photogrammetry, surface scanning, or micro-CT scanning. Here we use cephalopod beaks as an example as their size, thickness, transparency, and dry-sensitive nature make them particularly challenging. We developed a new, underwater, photogrammetry protocol in order to add these types of biological structures to...
