Exposure to elevated temperature during development affects bumblebee foraging behavior

Maxence Gérard, Bérénice Cariou, Maxime Henrion, Charlotte Descamps & Emily Baird
Bee foraging behavior provides a pollination service that has both ecological and economic benefits. However, bee population decline could directly affect the efficiency of this interaction. Among the drivers of this decline, global warming has been implicated as an emerging threat but exactly how increasing temperatures affect bee foraging behavior remains unexplored. Here, we assessed how exposure to elevated temperatures during development affects the foraging behavior and morphology of workers from commercial and wild Bombus...

Dust deposition in Red Sea corals

Alice Blanckaert
Climate change-related increase in seawater temperature has become a leading cause of coral bleaching and mortality. However, corals from the northern Red Sea show high thermal tolerance and no recorded massive bleaching event. This specific region is frequently subjected to intense dust storms, coming from the surrounding arid deserts, which are expected to increase in frequency and intensity in the future. The aerial dust deposition supplies essential bioelements to the water column. Here, we investigated...

Data from: A diversification relay race from Caribbean-Mesoamerica to the Andes: historical biogeography of Xylophanes hawkmoths

Xuankun Li, Chris Hamilton, Ryan Laurent, Liliana Ballesteros-Mejia, Amanda Markee, Rodolphe Rougerie, Ian Kitching & Akito Kawahara
The regions of the Andes and Caribbean-Mesoamerica are both hypothesized to be the cradle for many Neotropical lineages, but few studies have fully investigated the dynamics and interactions between Neotropical bioregions. The NewWorld hawkmoth genus Xylophanes is the most taxonomically diverse genus in the Sphingidae, with the highest endemism and richness in the Andes and Caribbean-Mesoamerica. We integrated phylogenomic and DNA barcode data and generated the first time-calibrated tree for this genus, covering 93.8% of...

Muscle systems and motility of early animals highlighted by cnidarians from the basal Cambrian

Xing Wang, Jean Vannier, Xiaoguang Yang, Lucas Leclère, Qiang Ou, Xikun Song, Tsuyoshi Komiya & Jian Han
Although fossil evidence suggests that various animal groups were able to move actively through their environment in the early stages of their evolution, virtually no direct information is available on the nature of their muscle systems. The origin of jellyfish swimming, for example, is of great interest to biologists. Exceptionally preserved muscles are described here in benthic peridermal olivooid medusozoans from the basal Cambrian of China (Kuanchuanpu Formation, ca. 535 Ma) that have direct equivalent...

Subtle limits to connectivity revealed by outlier loci within two divergent metapopulations of the deep-sea hydrothermal gastropod Ifremeria nautilei

Adrien Tran Lu Y, Stephanie Ruault, Claire Daguin-Thiébaut, Jade Castel, Nicolas Bierne, Thomas Broquet, Patrick Wincker, Aude Perdereau, Sophie Arnaud-Haond, Pierre-Alexandre Gagnaire, Didier Jollivet, Stephane Hourdez & François Bonhomme
Hydrothermal vents form archipelagos of ephemeral deep-sea habitats that raise interesting questions about the evolution and dynamics of the associated endemic fauna, constantly subject to extinction-recolonization processes. These metal-rich environments are coveted for the mineral resources they harbor, thus raising recent conservation concerns. The evolutionary fate and demographic resilience of hydrothermal species strongly depend on the degree of connectivity among and within their fragmented metapopulations. In the deep sea, however, assessing connectivity is difficult and...

Énonciation de la violence et violence de l’énonciation dans Dérangé que je suis d’Ali Zamir

Abdel Fatah NADJLOUDINE
La violence qui marque le discours contenu par le troisième roman d’Ali Zamir, aussi bien celui de Dérangé – narrateur et protagoniste – que celui des autres personnages, constitue l’objet de cet article. Il est question d’analyser le cadre énonciatif d’où émerge ce discours et les circonstances qui le précèdent afin de faire ressortir les diverses formes d’injustices subies par le narrateur et la multitude des procédés mis en œuvre par ce dernier pour décrire...

Kentukis de Samanta Schweblin. Connexions intimes

Pénélope Laurent
This article offers a study of the issue of intimacy in the science fiction novel Kentukis by Samanta Schweblin (2018) based on both textual analysis and the theory of fiction and relying on philosophy and psychoanalysis. The question will be to understand the phenomenon of the over exposure of intimacy in the societies of transparency, through the « kentuki » device. The owner of this connected object agrees to be spied on by a voyeur...

COVID-19 first lockdown as a window into language acquisition: associations between caregiver-child activities and vocabulary gains

Natalia Kartushina, Nivedita Mani, Aslı Aktan-Erciyes, Khadeejah Alaslani, Naomi Aldrich, Alaa Almohammadi, Haifa Alroqi, Lucy Anderson, Elena Andonova, Suzanne Aussems, Mireille Babineau, Mihaela Barokova, Christina Bergmann, Cara Cashon, Stephanie Custode, Alex de Carvalho, Nevena Dimitrova, Agnieszka Dynak, Rola Farah, Christopher Fennell, Anne-Caroline Fiévet, Michael Frank, Margarita Gavrilova, Hila Gendler-Shalev & Shannon Gibson
The COVID-19 pandemic, and the resulting closure of daycare centers worldwide, led to unprecedented changes in children’s learning environments. This period of increased time at home with caregivers, with limited access to external sources (e.g., daycares) provides a unique opportunity to examine the associations between the caregiver-child activities and children’s language development. The vocabularies of 1742 children aged 8-36 months across 13 countries and 12 languages were evaluated at the beginning and end of the...

Urbanization shapes the relation between density and melanin-based colouration in bird communities

Neyla Turak, Alice Monnier-Corbel, Mélanie Gouret & Adrien Frantz
Growing urbanization increasingly influences ecosystems worldwide. While the effects of urban conditions within species (through either plastic or evolutionary responses) have been widely studied, their potential influences among species (through environmental filter), especially concerning their colouration, remain poorly known. Here, we investigated whether avian communities breeding inside and outside a major European city (Paris) differ with regards to melanin-based plumage colouration. Melanins are heritable pigments present in many taxa and have a series of unique...

SOLAR-v: A new solar spectral irradiance dataset based on SOLAR/SOLSPEC observations during Solar Cycle 24

Mustapha Meftah
Variations of solar spectral irradiance are the most important natural factor in the terrestrial climate and as such, the time dependent spectral solar irradiance is a crucial input to any climate modelling. A better understanding of the long-term solar variations over timescales of the 11-year solar activity cycle and longer is very important. Thus, each new solar spectral irradiance dataset based on long-term observations represents a major interest and can be used for further investigations...

Paleohistological inferences of thermometabolic regimes in Notosuchia

Jorge Cubo, Paul Aubier, Mathieu Faure-Brac, Gaspard Martet, Romain Pellarin, Idriss Pelletan & Mariana Sena
Notosuchia is a group of mostly terrestrial crocodyliforms. The presence of a prominent crest overhanging the acetabulum, slender straight-shafted long bones with muscular insertions close to the joints, and a stable knee joint, suggests that they had an erect posture. This stance has been proposed to be linked to endothermy because it is present in mammals and birds, and it contributes to the efficiency of their respiratory systems. However, a bone paleohistological study unexpectedly suggested...

Origin, diversity, and biogeography of Antarctic scale worms (Polychaeta: Polynoidae): a wide-scale barcoding approach

Dominique Cowart, Stefano Schiaparelli, Maria Chiara Alvaro, Matteo Cecchetto, Anne-Sophie Le Port, Didier Jollivet & Stéphane Hourdez
Aim: The Antarctic marine environment hosts diversified and highly endemic benthos owing to its unique geologic and climatic history. Current warming trends have increased the urgency of understanding Antarctic species history to predict how environmental changes will impact ecosystem functioning. Antarctic benthic lineages have traditionally been examined under three hypotheses: 1) high endemism and local radiation, 2) emergence of deep-sea taxa through thermohaline circulation, 3) species migrations across the Polar Front. In this study, we...

Plant root growth against a mechanical obstacle: The early growth response of a maize root facing an axial resistance is consistent with the Lockhart model

Evelyne Kolb, Manon Quiros, Marie-Béatrice Bogeat-Triboulot & Etienne Couturier
Plant root growth is dramatically reduced in compacted soils, affecting the growth of the whole plant. Through a model experiment coupling force and kinematics measurements, we probed the force-growth relationship of a primary root contacting a stiff resisting obstacle, that mimics the strongest soil impedance variation encountered by a growing root. The growth of maize roots just emerging from a corseting agarose gel and contacting a force sensor (acting as an obstacle) was monitored by...

Taking Sides (2001) d’István Szabó : la figure du musicien face au régime nazi

Jean Du Verger
Le film Taking Sides (2001) du cinéaste hongrois István Szabó est une adaptation de la pièce éponyme du dramaturge britannique d’origine sud-africaine Ronald Harwood, qui en a signé lui-même l’adaptation cinématographique. Le film raconte l’instruction du procès en dénazification du grand chef d’orchestre allemand Wilhelm Furtwängler alors que le musicien a tenté de s’opposer au régime nazi. L’instruction met néanmoins en lumière les contradictions d’un personnage controversé et la complexité de la période. Szabó et...

Greater functional similarity in mobile compared to sessile assemblages colonizing artificial coastal habitats

Jean-Charles Leclerc, Naily Nashira Figueroa, Antonio Brante & Frédérique Viard
Among anthropogenic habitats built in the marine environment, floating and non-floating structures can be colonized by distinct assemblages. However, there is little knowledge whether these differences are also reflected in the functional structure. This study compared the functional diversity of sessile and mobile invertebrate assemblages that settle over 3 months on floating vs. non-floating artificial habitats, in two Chilean ports. Using morphological, trophic, behavioral, and life history traits, we found differences between mobile and sessile...
