IASI-FT Skin Temperature (from IASI/Metop-C)

Sarah Safieddine
IASI Skin Temperature is a monthly (L3), 1x1 degree global dataset of skin temperatures over land derived from the IASI satellite radiances data. The dataset consists of monthly mean TXT files. Each file is a grid organized by latitude (-90 to 89 °N) and longitude (-180 to 180 °E). Night and day data are separated based on the local time of IASI's overpass at each grid point. The sea grid points are filled using NaN....

Drosophila glue protects from predation

Virginie Courtier-Orgogozo, Flora Borne, Stéphane Prigent & Mathieu Molet
Animals can be permanently attached to a substrate in aerial environments at certain stages of their development. Pupa adhesion has evolved multiple times in insects and is thought to maintain the animal in a place where it is not detectable by predators. Here, we investigate whether pupa adhesion in Drosophila can also protect the animal by preventing potential predators from detaching the pupa. We measured the adhesion of Drosophila species sampled from the same area...

Data from: Increasing dependence of lowland populations on mountain water resources

Daniel Viviroli, Matti Kummu, Michel Meybeck, Marko Kallio & Yoshihide Wada
Mountain areas provide disproportionally high runoff in many parts of the world, and here we quantify for the first time their importance for water resources and food production from the viewpoint of the lowland areas downstream. The dataset maps the degree to which lowland areas potentially depend on runoff contributions from mountain areas (39% of land mass) between the 1960s and the 2040s.

Structural defence is coupled with the leaf economic spectrum across saplings of spiny species

Mohammed Armani, Uromi M. Goodale, Tristan Charles-Dominique, Kasey E. Barton, Xin Yao & Kyle W. Tomlinson
Given that the rate of resource capture constrains plant growth and defence, understanding the linkage between the leaf economic spectrum (LES) and defence and how it contributes to growth is central to predicting species performance. In spite of the prevalence of spiny plants in many plant communities, little is known about how the LES relates to defence and growth rate across these species. We grew 42 spiny species, from diverse environments, under common garden conditions...

Polygenic basis for adaptive morphological variation in a threatened Aotearoa | New Zealand bird, the hihi (Notiomystis cincta)

Laura Duntsch, Barbara Tomotani, Pierre De Villemereuil, Patricia Brekke, Kate Lee, John Ewen & Anna Santure
To predict if a threatened species can adapt to changing selective pressures, it is crucial to understand the genetic basis of adaptive traits, especially in species historically affected by severe bottlenecks. We estimated the heritability of three hihi (Notiomystis cincta) morphological traits known to be under selection: nestling tarsus length, body mass and head-bill length, using 523 individuals and 39,699 single nucleotide polymorphisms (SNPs) from a 50K Affymetrix SNP chip. We then examined the genetic...

Data from: Seascape genomics of the sugar kelp Saccharina latissima along the North Eastern Atlantic latitudinal gradient

Jaromir Guzinski, Paolo Ruggeri, Marion Ballenghien, Stephane Mauger, Bertrand Jacquemin, Chloe Jollivet, Jerome Coudret, Lucie Jaugeon, Christophe Destombe & Myriam Valero
Temperature is one of the most important range-limiting factors for many seaweeds. Driven by the recent climatic changes, rapid northward shifts of species’ distribution ranges can potentially modify the phylogeographic signature of Last Glacial Maximum. We explored this question in detail in the cold-tolerant kelp species Saccharina latissima, using microsatellites and double digest restriction site-associated DNA sequencing (ddRAD-seq) derived single nucleotide polymorphisms (SNPs) to analyze the genetic diversity and structure in 11 sites spanning the...

Data from: Trait evolution and historical biogeography shape assemblages of annual killifish

Andrew Helmstetter, Alexander Papadopulos, Javier Igea & Tom Van Dooren
Aim: Different species assemblages of annual killifish possess replicated body size distributions yet have unique sets of species in each area of endemism. Here, we use models of trait evolution and historical biogeography to discover how size variation originated and has been restructured. Location: South America. Taxon: Austrolebias (Cyprinodontiformes). Methods: We sampled 63 individuals from 26 Austrolebias species. Using phylogenetic trees (BEAST2), data on environmental variables at sampling locations and size data we compare different...

Lee and Daunizeau choice data from: Trading mental effort for confidence in the metacognitive control of value-based decision-making

Douglas Lee & Jean Daunizeau
Why do we carefully ponder some decisions, but not others? In this work, we derive a computational model of the metacognitive control of decisions or MCD. In brief, we assume that fast and automatic processes first provide an initial (and largely uncertain) representation of options' values, yielding prior estimates of decision difficulty. This uncertain value representation is then refined by deploying cognitive (e.g., attentional, mnesic) resources, the allocation of which is controlled by an effort-confidence...

Unidirectional response to bidirectional selection on body size. I. Phenotypic, life history and endocrine response

Clémentine Renneville, Alexis Millot, Simon Agostini, David Carmignac, Gersende Maugars, Sylvie Dufour, Arnaud Le Rouzic & Eric Edeline
Anthropogenic perturbations such as harvesting often select against a large body size and are predicted to induce rapid evolution towards smaller body sizes and earlier maturation. However, body-size evolvability and, hence, adaptability to anthropogenic perturbations remain seldom evaluated in wild populations. Here, we use a laboratory experiment over 6 generations to measure the ability of wild-caught medaka fish (Oryzias latipes) to evolve in response to bidirectional size-dependent selection mimicking opposite harvest regimes. Specifically, we imposed...

Parkinson’s disease propagation using MRI biomarkers and partial least squares path modeling

Nadya Pyatigorskaya, Lydia Yahia Cherif, Romain Valabregue, Rahul Gaurav, Fatma Gargouri, Claire Ewenczyk, Cecile Gallea, Sara Fernandez-Vidal, Isabelle Arnulf, Marie Vidailhet & Stephane Lehericy
Objectives: The classical Braak neuropathological staging model in Parkinson's disease (PD) suggests that brain lesions progress from the medulla oblongata to the cortex. An alternative model in which neurodegeneration first occurs in the cortex has also been proposed. These two models may correspond to different patient phenotypes. To test these two models and investigate if they were influenced by the presence of rapid eye movement sleep behavior disorder (RBD) we used multimodal MRI and Partial...

Dataset for METAPOPGEN 2.0: a multi-locus genetic simulator to model populations of large size

Marco Andrello, Christelle Noirot, Florence Débarre & Stéphanie Manel
Multi-locus genetic processes in subdivided populations can be complex and difficult to interpret using theoretical population genetics models. Genetic simulators offer a valid alternative to study multi-locus genetic processes in arbitrarily complex scenarios. However, the use of forward-in-time simulators in realistic scenarios involving high numbers of individuals distributed in multiple local populations is limited by computation time and memory requirements. These limitations increase with the number of simulated individuals. We developed a genetic simulator, MetaPopGen...

Stable species boundaries despite ten million years of hybridization in tropical eels

Julia Barth, Chrysoula Gubili, Michael Matschiner, Ole Tørresen, Shun Watanabe, Bernd Egger, Yu-San Han, Eric Feunteun, Ruben Sommaruga, Robert Jehle & Robert Schabetsberger
Genomic evidence is increasingly underpinning that hybridization between taxa is commonplace, challenging our views on the mechanisms that maintain their boundaries. Here, we focus on seven catadromous eel species (genus Anguilla), and use genome-wide sequence data from more than 450 individuals sampled across the tropical Indo-Pacific, morphological information, and three newly assembled draft genomes to compare contemporary patterns of hybridization with signatures of past gene flow across a time-calibrated phylogeny. We show that the seven...

Exploring the genetic consequences of clonality in haplodiplontic taxa

Stacy Krueger-Hadfield, Marie-Laure Guillemin, Christophe Destombe, Myriam Valero & Solenn Stoeckel
Partially clonality is an incredibly common reproductive mode found across all the major eukaryotic lineages. Yet, population genetic theory is based on exclusive sexuality or exclusive asexuality and partial clonality is often ignored. This is particularly true in haplodiplontic eukaryotes, including algae, ferns, mosses, and fungi, where somatic development occurs in both the haploid and diploid stages. Haplodiplontic life cycles are predicted to be correlated with asexuality, but tests of this prediction are rare. Moreover,...
