Size of the grid: 180 lines and 361 columns....

Les restes organiques minéralisés : un nouveau champ d’investigation en contexte funéraire. Exemple de la nécropole de Merxheim « Obere Reben » (Haut-Rhin)

Armelle Charrié-Duhaut, Fabienne Médard, Clotilde Proust & Hélène Barrand-Emam
Rarement intelligibles, les restes organiques minéralisés représentent un potentiel informatif sous-estimé. Directement liés à l’étude de l’objet archéologique en métal qui leur sert de support et a permis leur conservation, ils constituent un champ d’investigation quasi inépuisable et d’une grande diversité. La complexité intrinsèque des matériaux, la variabilité des dégradations possibles, la prise en compte des contextes d’enfouissement impliquent, cependant, de repenser la chaîne opératoire de l’archéologie, depuis la prescription de fouille jusqu’aux lieux de...

Trait-dependency of trophic interactions in zooplankton food webs

Florian Vincent, Andrea Bertolo, Gérard Lacroix, Maud Mouchet & Eric Edeline
Anthropogenic change in the abundance or identity of dominant top predators may induce reorganizations in whole food webs. Predicting these reorganizations requires identifying the biological rules that govern trophic niches. However, we still lack a detailed understanding of the respective contributions of body size, behaviour (e.g., match between predator hunting mode and prey antipredator strategy), phylogeny and/or ontogeny in determining both the presence and strength of trophic interactions. Here, we address this question by measuring...

Conservation genetics of Armeria belgenciencis

Alex Baumel, Frédéric Médail, Marianick Juin, Thibault Paquier, Marie Clares, Perrine Laffargue, Hélène Lutard, Lara Dixon & Mathias Pires
This the data set of the paper "Population genetic structure and management perspectives for Armeria belgenciencis, a narrow endemic plant from Provence (France)" published in Plant Ecology and Evolution: ###############. The genetic structure of Armeria belgenciensis and geographically close populations of Armeria arenaria was analyzed on the basis of 328 AFLP markers using model-based and model-free clustering methods. In addition, flowering phenology was estimated to address the possibility of pre-zygotic isolation between A. belgenciensis and...

Data from: Cranial evolution in the extinct Rodrigues Island owl Otus murivorus (Strigidae), associated with unexpected ecological adaptations

Antoine Louchart, Anaïs Duhamel, Julian Hume, Pauline Guenser & Céline Salaviale
Island birds that were victim of anthropic extinctions were often more specialist species, having evolved their most distinctive features in isolation. Here we studied a fossil cranium of the ‘giant’ extinct scops owl Otus murivorus from Rodrigues Island (Mascarene Islands, southwestern Indian Ocean), to determine any potential unique characters. The fossil and extant strigids were imaged through x-ray microtomography, providing 3D views of external and internal (endocast, inner ear) cranial structures. Geometric morphometrics and analyses...

Data from: Are fission-fusion dynamics consistent among populations? A large-scale study with Cape buffalo

Elodie Wielgus, Daniel Cornélis, Michel De Garine-Wichatitsky, Bradley Cain, Hervé Fritz, Eve Miguel, Hugo Valls-Fox, Alexandre Caron & Simon Chamaillé-Jammes
Fission-fusion dynamics allow animals to manage costs and benefits of group living by adjusting group size. The degree of intraspecific variation in fission-fusion dynamics across the geographical range is poorly known. During 2008-2016, 38 adult female Cape buffalo were equipped with GPS collars in three populations located in different protected areas (Gonarezhou National Park and Hwange National Park, Zimbabwe; Kruger National Park, South Africa) to investigate the patterns and environmental drivers of fission-fusion dynamics among...

Disentangling the roles of bottom-up and top-down drivers in the trade-off between food acquisition and safety in prey with multiple predators

Olivier Pays, Pierrick Blanchard, Simon Chamaillé-Jammes, Marion Valeix, Andrew Loveridge, David Macdonald, Stéphanie Périquet, Esther Van Der Meer, Patrick Duncan, Godfrey Mtare & Herve Fritz
1. Prey face a trade-off between acquiring food and avoiding predation, but food availability, and therefore its effect, is rarely measured in field studies investigating non-lethal effects of predation. The main aim of this study is to investigate the role of the presence of predators in the functional adjustments of feeding parameters with patch quality in a medium-size herbivore. 2. In Hwange National Park (Zimbabwe), we set up an experiment by manipulating, over two years,...

Honey bee lifespan: the critical role of pre-foraging stage

Alberto Prado, Fabrice Requier, Didier Crauser, Yves Le Conte, Vincent Bretagnolle & Cedric Alaux
Assessing the various anthropogenic pressures imposed on honey bees requires characterizing the patterns and drivers of natural mortality. Using automated life-long individual monitoring devices, we monitored worker bees in different geographical, seasonal and colony contexts creating a broad range of hive conditions. We measured their life-history traits and notably assessed whether lifespan is influenced by pre-foraging flight experience. Our results show that the age at the first flight and onset of foraging are critical factors...

Exploration, analyse et gestion d’environnements archéologiques virtuels

Jean-Baptiste Barreau
La numérisation des sites et des objets archéologiques permet de mieux comprendre leur fonctionnement et de proposer des reconstitutions de leur état passé. Cette technologie permet de restituer un « environnement archéologique 3D » constitué, en plus des architectures statiques, de simulations physiques et d’êtres vivants. Lorsque celui-ci est simulé à l’aide de techniques interactives et immersives de réalité virtuelle, on parle alors d’un « environnement archéologique virtuel » ; les archéologues peuvent l’explorer, l’analyser...

Data from: Foraging behaviour and habitat-use drives niche segregation in sibling seabird species

Ryan Reisinger, Tegan Carpenter-Kling, Maëlle Connan, Yves Cherel & Pierre Pistorius
To mediate competition, similar sympatric species are assumed to utilise different resources, or the same but geographically separated resources. The two giant petrels (Macronectes spp.) are intriguing in that they are morphologically similar seabirds with overlapping diets and distributions. To better understand the mechanisms allowing their co-existence, we investigated intra- and interspecific niche segregation at Marion Island (Southern Indian Ocean), one of the few localities where they breed in sympatry. We used GPS tracks from...

Data from: Reproductives and eggs trigger worker vibration in a subterranean termite

Fanny Ruhland, Marion Moulin, Marina Choppin, Joël Meunier & Christophe Lucas
In insect societies, the presence of reproductives or eggs has been shown to shape several biological traits in the colony members. Social interactions are one of these traits, that involve modification of the communication system of the entire colony. Many studies described the role of chemical compounds and dominance behaviors in the presence of reproductive but vibratory behaviors received very few investigations. Yet, vibratory behaviors are ideal candidates, particularly for subterranean species like termites, as...

Data from: Canonical correlations reveal adaptive loci and phenotypic responses to climate in perennial ryegrass

José L. Blanco-Pastor, Philippe Barre, Thomas Keep, Thomas Ledauphin, Abraham Escobar-Gutiérrez, Anna Maria Roschanski, Evelyn Willner, Klaus Dehmer, Matthew Hegarty, Hilde Muylle, Elisabeth Veeckman, Klaas Vandepoele, Tom Ruttink, Isabel Roldán-Ruiz, Stéphanie Manel & Jean-Paul Sampoux
Germplasm from perennial ryegrass (Lolium perenne L.) natural populations is useful for breeding because of its adaptation to a wide range of climates. Climate-adaptive genes can be detected from associations between genotype, phenotype and climate but an integrated framework for the analysis of these three sources of information is lacking. We used two approaches to identify adaptive loci in perennial ryegrass and their effect on phenotypic traits. First, we combined Genome-Environment Association (GEA) and GWAS...

Young frigatebirds learn how to compensate for wind-drift

Joe Wynn, Oliver Padget, Julien Collet, Aurélien Prudor, Alexandre Corbeau & Henri Weimerskirch
Compensating for wind drift can improve goalward flight efficiency in animal taxa, especially amongst those that rely on thermal soaring to travel large distances. Little is known, however, about how animals acquire this ability. The great frigatebird (Fregata minor) exemplifies the challenges of wind drift compensation because it lives a highly pelagic lifestyle, traveling very long distances over the open ocean but without the ability to land on water. Using GPS tracks from fledgling frigatebirds,...

Data from: Plasticity matches phenotype to local conditions despite genetic homogeneity across 13 snake populations

Xavier Bonnet
In a widespread species, a matching of phenotypic traits to local environmental optima is generally attributed to site-specific adaptation. However, the same matching can occur via adaptive plasticity, without requiring genetic differences among populations. Adult sea kraits (Laticauda saintgironsi) are highly philopatric to small islands, but the entire population within the Neo-Caledonian lagoon is genetically homogenous because females migrate to the mainland to lay their eggs at communal sites; recruits disperse before settling, mixing up...

La Bioarchéologie en France : état des lieux, enjeux et perspectives

Rose-Marie Arbogast & Margareta Tengberg
La bioarchéologie est l’étude des vestiges biologiques recueillis dans le cadre de fouilles archéologiques tels que les restes végétaux et animaux, mais aussi leurs composants physico-chimiques, génétiques et les traces de substances organiques (lait, graisses, cires…). Elle regroupe un très large éventail d’approches et de disciplines : archéozoologie, archéobotanique, analyses chimiques, isotopiques ou moléculaires, menées à des échelles très diverses et envisagées de façon croisée. Son évolution récente est marquée par un important renouvellement tant...

Aux dimensions de l’image dans l’étude des représentations gravées néolithiques

Serge Cassen & Valentin Grimaud
En voulant témoigner des gravures qu’ils apercevaient sur les rochers, les stèles et les parois des tombeaux néolithiques de l’Europe occidentale, les premiers archéologues en recherche d’une représentation tentent de restituer la morphologie des supports par le jeu de la lumière sur le relief de la pierre. Mais par une volonté compréhensible de clarifier les tracés en éliminant le détail naturel, la troisième dimension va progressivement se perdre jusqu’à atteindre, dans la seconde moitié du...

Nouveau protocole de prélèvement et de préparation des macro‐charbons pour une généralisation des études anthraco‐chronologiques

Benoit Brossier, Philippe Poirier, Christophe Vaschalde, Isabel Figueiral , Lucie Chabal & Marylise Marmara
Les développements méthodologiques en anthracologie permettent actuellement d’obtenir des spectres de fréquences de taxons représentatifs des environnements passés, moyennant des conditions précises d’échantillonnage et de tamisage. Pourtant, d’autres informations sont disponibles dans les charbons de bois, en particulier ceux de taille pluricentimétrique. Depuis le début des années 2000, plusieurs recherches se fondent sur les informations de morphologie des cernes (courbure, largeur, etc.) des charbons de bois retrouvés en contexte archéologique, afin de répondre à des...

Archéobios : Archives biologiques et biomatériaux en contexte archéologique

Isabelle Rodet-Belarbi, Lionel Gourichon & Isabelle Théry-Parisot
L’école thématique Archéobios (I. Théry-Parisot et L. Gourichon, CEPAM-UMR 7264) a été conçue comme un trait d’union entre les archéologues et les spécialistes, souvent absents sur le terrain. Les restes biologiques sont des archives archéologiques au fort potentiel informatif dont les traces sont parfois ténues et fragiles. Leur étude répond à des exigences d’échantillonnage, de prélèvement, de conservation spécifiques à chaque matériau, et à des problématiques précises. Si les gestes lors des fouilles sont une...
