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...

Codes and data from: The effect of habitat choice on evolutionary rescue in subdivided populations

Peter Czuppon, François Blanquart, Hildegard Uecker & Florence Débarre
Evolutionary rescue is the process by which a population, in response to an environmental change, successfully avoids extinction through adaptation. In spatially structured environments, dispersal can affect the probability of rescue. Here, we model an environment consisting of patches that degrade one after another, and we investigate the probability of rescue by a mutant adapted to the degraded habitat. We focus on the effects of dispersal and of immigration biases. We find that the probability...

Supplementary material to: Segmental series and size: clade-wide investigation of molar proportions reveals a major evolutionary allometry in the dentition of placental mammals

Guillaume Billet & Jérémie Bardin
Iterative segments such as teeth or limbs are a widespread characteristic of living organisms. While their proportions may be governed by similar developmental rules in vertebrates, there is no emerging pattern as regards their relation to size. Placental mammals span eight orders of magnitude in body size and show a wide spectrum of dietary habits associated with size and reflected in their dentitions, especially molars. Although variation in size constitutes an important determinant for variation...

LAM output for: The excitation of the Madden-Julian Oscillation as part of atmospheric adjustment to equatorial heating

Yu Liang, Alexey Fedorov, Patrick Haertel & Vladimir Zeitlin
We study the adjustment of the tropical atmosphere to localized surface heating using a Lagrangian atmospheric model(LAM) that simulates a realistic Madden-Julian Oscillation (MJO) – the dominant, eastward-propagating mode of tropical intraseasonal variability modulating atmospheric convection. Idealized warm sea surface temperature (SST) anomalies of different aspect ratios and magnitudes are imposed in the equatorial Indian Ocean during MJO-neutral conditions and then maintained for 15 days. Throughout these experiments, we observe a robust generation of an...

Bud traits and post-fire responses of Cerrado woody species, Southeastern Brazil

Marco Antonio Chiminazzo, Aline Bertolosi Bombo, Tristan Charles-Dominique & Alessandra Fidelis
1) Species growing in fire-prone savannas usually persist by resprouting from their buds. In this study, we evaluated how various persistence traits allow bud protection for improved survival in fire-prone ecosystems. 2) Using an integrative morphological and macroanatomical approach, we analyzed how woody plants protect their buds. We tested bud protection at the community level and evaluated: a) how bud protection changes along a fire frequency gradient, b) if it differs between shrubs and trees...

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...

RochElec : Geoelectrical investigations on the Rochechouart impact structure (France)

Yoann Quesnel, Pascal Sailhac, Johana Lofi, Philippe Lambert, Pierre Rochette, Minoru Uehara & Christian Camerlynck
The Rochelec dataset gathers petrophysical and geoelectrical data from the Rochechouart impact structure (France). Since 2017, about 10 geophysical field campaigns were performed on this eroded structure. Among other techniques, geophysical downhole logging, electrical resistivity tomography and controlled-source audiomagnetotelluric data were acquired. In parallel, we measured the electrical resistivity and porosity of some core samples coming from drillings performed in fall 2017 at several sites of the impact structure. These multiscale electric data allows to...

Data from: Wintering bird communities are tracking climate change faster than breeding communities

Aleksi Lehikoinen, Åke Lindström, Andrea Santangeli, Päivi Sirkiä, Lluis Brotons, Vincent Devictor, Jaanus Elts, Ruud P. B. Fobben, Henning Heldbjerg, Sergi Herrando, Marc Herremans, Marie-Anne R. Hudson, Frederic Jiguet, Alison Johnston, Romain Lorrilliere, Emma-Liina Marjakangas, Nicole L. Michel, Charlotte M. Moshøj, Renno Nellis, Jean-Yves Paquet, Adam C. Smith, Tibor Szep & Chris Van Turnhout
1. Global climate change is driving species’ distributions towards the poles and mountain tops during both non-breeding and breeding seasons, leading to changes in the composition of natural communities. However, the degree of season differences in climate-driven community shifts has not been thoroughly investigated at large spatial scales. 2. We compared the rates of change in the community composition during both winter (non-breeding season) and summer (breeding) and their relation to temperature changes. 3. Based...

Comparison of an extracellular vs. total DNA extraction approach for environmental DNA-based monitoring of sediment biota

Anthony Chariton, Johan Pansu, Grant Hose & Michelle Chapman
Monitoring sediment biota is an essential step for the quality assessment of aquatic ecosystems. Environmental DNA-based approaches for biomonitoring are increasing in popularity; yet, commercial kits and protocols for extracting total DNA from sediments remain expensive and time-consuming. Furthermore, they can accommodate only small amounts of sediments, potentially preventing an adequate representation of local biodiversity, especially for macro-organisms. Here, we assessed the reliability of a cost- and time- effective extracellular DNA extraction approach, able to...

Comparison of size-structured and species-level trophic networks reveals antagonistic effects of temperature on vertical trophic diversity at the population and species level

Willem Bonnaffé, Alain Danet, Stephane Legendre & Eric Edeline
It is predicted that warmer conditions should lead to a loss of trophic levels, as larger bodied consumers, which occupy higher trophic levels, experience higher metabolic costs at high temperature. Yet, it is unclear whether this prediction is consistent with the effect of warming on the trophic structure of natural systems. Furthermore, effects of temperature at the species level, which arise through a change in species composition, may differ from those at the population level,...

Data from: A unique, large-sized stem-Odonata (Insecta) found in the early Pennsylvanian of New Brunswick (Canada)

Olivier Béthoux, Rowan E. Norrad, Matthew Stimson, Olivia King, Luke F. Allen, Isabelle Deregnaucourt, Steven J. Hinds, Jake H. Lewis & Jörg W. Schneider
A stem-relative of dragon- and damselflies, Brunellopteron norradi Béthoux, Deregnaucourt and Norrad gen. et spec. nov., is documented based on a specimen found at Robertson Point (Grand Lake, New Brunswick, Canada; Sunburry Creek Formation; early Moscovian, Pennsylvanian) and preserving the basal half of a hindwing. A comparative analysis of the evolution of wing venation in early odonates demonstrates that it belongs to a yet poorly documented subset of species. Specifically, it displays a MP+CuA fusion,...

Evolution vers la 3ème dimension pour une meilleure compréhension du microenvironnement immunitaire dans les tumeurs

Laïla Letaïef, Safa Azar, Isabelle Brunet, Hélène Kaplon, Jean-Luc Teillaud & Marie-Caroline Dieu-Nosjean
L’analyse du microenvironnement d’un tissu fournit une manne d’informations quasiment illimitées pour les chercheurs et les cliniciens. Les avancées très récentes des techniques d’immunohistochimie (IHC) et d’immunofluorescence (IF) ont permis de mieux appréhender la complexité du microenvironnement tissulaire notamment dans les cancers. Au travers de plusieurs exemples développés dans les cancers du poumon, les limites de l’IHC/IF ont été repoussées pour mieux répondre à des questions comme : est-ce que le niveau d’organisation in situ...

Combined palaeohistological and isotopic inferences of thermometabolism in extinct Neosuchia, using Goniopholis and Dyrosaurus (Pseudosuchia: Crocodylomorpha) as case studies

Mathieu Faure-Brac, Romain Amiot, Christian De Muizon, Jorge Cubo & Christophe Lécuyer
The evolution of thermometabolism in pseudosuchians (Late Triassic to the present) remains a partly unsolved issue: extant taxa (crocodilians) are ectothermic, but the clade was inferred ancestrally endothermic. Here we inferred the thermometabolic regime of two neosuchian groups, Goniopholididae (Early Jurassic to Late Cretaceous) and Dyrosauridae (Middle Cretaceous to Late Eocene), close relatives of extant crocodilians, in order to elucidate the evolutionary pattern across Metasuchia (Early Jurassic to the present), a clade comprising Neosuchia (Early...

Data from: Kin relationships in cultural species of the marine realm: case study of a matrilineal social group of sperm whales off Mauritius Island, Indian Ocean

Jean-Luc Jung, François Sarano, Justine Girardet, Véronique Sarano, Hugues Vitry, Axel Preud'homme, René Heuzey, Ana Maria Garcia Cegarra, Bénédicte Madon, Fabienne Delfour, Hervé Glotin & Olivier Adam
Understanding the organization and dynamics of social groups of marine mammals through the study of kin relationships is particularly challenging. Here we studied a stable social group of sperm whales off Mauritius, using underwater observations, individual-specific identification, non-invasive sampling, and genetic analyses based on mitochondrial sequencing and microsatellite profiling. Twenty-four sperm whales were sampled between 2017 and 2019. All individuals except one adult female shared the same mtDNA haplotype—one that is rare in the Western...

Data from: Grylloblattidan insects from Sperbersbach and Cabarz (Germany), two new early Permian and insect-rich localities

Yingying Cui, Stephan Brauner, Jörg Schneider & Olivier Béthoux
New fossil insect specimens from two new localities from Germany, namely Sperbersbach and Cabarz (Goldlauter Formation; early Permian), and belonging to the Grylloblattida, are described. Abundant material is assigned to Pictoborella clara n. gen. n. sp., regarded as closely related to Pictoborella germanica (Prokop, Weiss, Dechambre and Nel, 2012) n. comb., from the Saar-Nahe Basin (Germany; early Permian). Liomopterum fuscatum n. sp., represented by fewer specimens, is delimited based on previously published and new data...
