Data from: Large feet are beneficial for eiders Somateria mollissima

Anders Pape Møller & Karsten Laursen
1. Many waterbirds have fully (totipalmate) or partially webbed (palmate) feet that are used for locomotion in aquatic environments. 2. If webbed feet and wings both contribute to efficient diving, we predicted a positive association between the area of webbed feet and the size of the frontal locomotor apparatus (wing area, heart mass and breast muscle, after adjusting for any partial effects of body size). We predicted that individuals able to acquire more and better...

Data from: Which frugivory‐related traits facilitated historical long‐distance dispersal in the custard apple family (Annonaceae)?

Renske E. Onstein, W. Daniel Kissling, Lars W. Chatrou, Thomas L. P. Couvreur, Hélène Morlon & Hervé Sauquet
Aim Long-distance dispersal has contributed to the disjunct biogeographical distribution of rain forest plants – something that has fascinated biogeographers since Humboldt’s time. However, the dispersal ‘agent’ for these tropical plant lineages remains puzzling. Here, we investigate which frugivory-related traits may have facilitated past intercontinental long-distance dispersal in the custard apple family (Annonaceae), a major vertebrate-dispersed tropical plant family. We hypothesize that long-distance dispersal was associated with the evolution of traits related to dispersal by...

Data from: Cortical recruitment determines learning dynamics and strategy

Sebastian Ceballo, Alexandre Kempf, Jacques Bourg, Zuzanna Piwkowska, Aurélie Daret, Pierre Pinson, Thomas Deneux, Simon Rumpel & Brice Bathellier
Salience is a broad and widely used concept in neuroscience whose neuronal correlates, however, remain elusive. In behavioral conditioning, salience is used to explain various effects, such as stimulus overshadowing, and refers to how fast and strongly a stimulus can be associated with a conditioned event. Here, we identify sounds of equal intensity and perceptual detectability, which due to their spectro-temporal content recruit different levels of population activity in mouse auditory cortex. When using these...

Data from: New physiological bench test reproducing noctural breathing pattern of patients with sleep disordered breathing

Petitjean Michel, Yann Rétory, Amélie Sagniez, Sébastien HARDY, François Cottin, Gabriel Roisman & Shuo Liu
Previous studies have shown that Automatic Positive Airway Pressure (APAP) devices display different behaviors when connected to a bench using theoretical respiratory cycle scripts. However, these scripts are limited and do not simulate physiological behavior during the night. Our aim was to develop a physiological bench that is able to simulate patient breathing airflow by integrating polygraph data. We developed an algorithm analyzing polygraph data and transformed this information into digital inputs required by the...

Wide spectrum and high frequency of genomic structural variation, including transposable elements, in large double stranded DNA viruses

Clement Gilbert, Elisabeth Herniou, Yannis Moreau, Nicolas Lévêque, Carine Meignin, Laurent Daeffler, Brian Federici, Richard Cordaux & Vincent Loiseau
Our knowledge of the diversity and frequency of genomic structural variation segregating in populations of large double stranded (ds) DNA viruses is limited. Here we sequenced the genome of a baculovirus (AcMNPV) purified from beet armyworm (Spodoptera exigua) larvae at depths >195,000X using both short-read (Illumina) and long-read (PacBio) technologies. Using a pipeline relying on hierarchical clustering of structural variants (SVs) detected in individual short- and long-reads by six variant callers, we identified a total...

Holocene extinctions of a top predator – effects of time, habitat area and habitat subdivision

Göran Englund, Gunnar Öhlund, Fredrik Olajos, Anders Finstad, Celine Bellard & Bernard Hugueny
1. Loss of habitat and changes in the spatial configuration of habitats are major drivers of species extinctions, but the response to these drivers differs between organisms. To advance theory on how extinction risk from different types of habitat alteration relate to species-specific traits, there is a need for studies on the long-term extinction dynamic of individual species. 2. The goal of this study was to quantify how habitat area and the spatial configuration of...

3D models of planetary bodies

Frederic Schmidt, Gaspard Salomon & Laurent Daumas
Current technology allows us to print various object in 3D for teaching and education purposes, including for the visually disabled [1]. The use of 3D printer for planetary science has been perceived since the premises of this industrial revolution [2]. In parallel several services and web-services have been developed to help the users to create their own model [3]. We propose here a database of ready-to-use 3D model of planetary bodies at full scale.

Data from: Multiple components of environmental change drive populations of breeding waders in seminatural grasslands

Karsten Laursen, Javier Balbontín, Ole Thorup, Henrik Haaning Nielsen, Tommy Asferg & Anders Pape Møller
Environments are rapidly changing due to climate change, land-use, intensive agriculture and the impact of hunting on predator populations. Here we analysed long-term data recorded during 1928-2014 on the size of breeding populations of waders at two large nature reserves in Denmark, Vejlerne and Tipperne, to determine the effects of components of environmental change on breeding populations of waders. Waders are closely associated with coastal marshes and meadows, and such habitats have been reduced extensively...
