Data from: Population closure and the bias-precision trade-off in Spatial Capture-Recapture

Pierre Dupont, Cyril Milleret, Olivier Gimenez & Richard Bischof
1. Spatial capture-recapture (SCR) is an increasingly popular method for estimating ecological parameters. This method often relies on data collected over relatively long sampling periods. While longer sampling periods can yield larger sample sizes and thus increase precision of estimates, they also increase the risk of violating the closure assumption, thereby potentially introducing bias. The sampling period characteristics are therefore likely to play an important role in this bias-precision tradeoff. Yet few studies have studied...

Data from: The preference-performance relationship as a means of classifying parasitoids according to their specialization degree

Lucie S. Monticelli, Le Thu Ha Nguyen, Edwige Amiens-Desneux, Chen Luo, Anne-Violette Lavoir, Jean-Luc Gatti & Nicolas Desneux
Host range in parasitoids could be described by the preference-performance hypothesis (PPH) where preference is defined as host acceptance and performance is defined as the sum of all species on which parasitoid offspring can complete their life cycle. The PPH predicts that highly suitable hosts will be preferred by ovipositing females. However, generalist parasitoids may not conform to this hypothesis if they attack a large range of hosts of varying suitability. Under laboratory conditions, we...

Data from: At sea vocal repertoire of a foraging seabird

Andréa Thiebault, Isabelle Charrier, Pierre Pistorius & Thierry Aubin
Seabirds spend most of their time at sea, yet our knowledge of their activities and behaviour is limited due to difficulties of in-situ data collection. In particular, we know virtually nothing about their acoustic communication when at sea. We benefited from the recent development of miniaturised audio-recording devices to deployacoustic recorders on breeding Cape gannets Morus capensis to study their vocal activity while foraging. Call sequences were recorded on 1718 occasions, from which acoustic variables...

Data from: Metapopulation vicariance, age of island taxa and dispersal: a case study using the pacific plant genus Planchonella (Sapotaceae)

Ulf Swenson, J. Christopher Havran, Jérôme Munzinger, Stephen Mcloughlin & Stephan Nylinder
Oceanic islands originate from volcanism or tectonic activity without connections to continental landmasses, are colonized by organisms, and eventually vanish due to erosion and subsidence. Colonization of oceanic islands occurs through long-distance dispersals or metapopulation vicariance, the latter resulting in lineages being older than the islands they inhabit. If metapopulation vicariance is valid, island ages cannot be reliably used to provide maximum age constraints for molecular dating. We explore the relationships between the ages of...

Sexual isolation with and without ecological isolation in marine isopods Jaera albifrons and J. praehirsuta

Ambre Ribardière, Elsa Pabion, Jérôme Coudret, Claire Daguin-Thiébaut, Céline Houbin, Stéphane Loisel, Sébastien Henry & Thomas Broquet
Sexual barriers associated with mate choice are often found to be associated with some level of ecological isolation between species. The independence and relative strength of sexual isolation are thus difficult to assess. Here we take advantage of a pair of marine isopod species (Jaera albifronsand J. praehirsuta) that show sexual isolation and coexist in populations where they share the same microhabitat or not (i.e. without or with ecological isolation). We estimated the strength of...

Data from: Diffusion tensor imaging reveals diffuse white matter injuries in locked-in syndrome patients

Mylène L. Leonard, Felix R. Renard, Laura H. Harsan, Julien P. Pottecher, Marc B. Braun, Francis S. Schneider, Pierre F. Froehlig, Frédéric B. Blanc, Daniel R. Roquet, Sophie A. Achard, Nicolas M. Meyer & Stéphane K. Kremer
Locked-in syndrome (LIS) is a state of quadriplegia and anarthria with preserved consciousness, which is generally triggered by a disruption of specific white matter fiber tracts, following a lesion in the ventral part of the pons. However, the impact of focal lesions on the whole brain white matter microstructure and structural connectivity pathways remains unknown. We used diffusion tensor magnetic resonance imaging (DT-MRI) and tract-based statistics to characterise the whole white matter tracts in seven...

Data from: How many cubs can a mum nurse? Maternal age and size influence litter size in polar bears

Dorinda Marie Folio, Jon Aars, Olivier Gimenez, Andrew E. Derocher, Oystein Wiig & Sarah Cubaynes
Life history theory predicts that females' age and size affect the level of maternal investment in current reproduction, balanced against future reproductive effort, maintenance and survival. Using long-term (30 years) individual data on 193 female polar bears (Ursus maritimus), we assessed age- and size-specific variation on litter size. Litter size varied with maternal age, younger females had higher chances of losing a cub during their first months of life. Results suggest an improvement of reproductive...

Data from: How do soil microorganisms respond to N, P and NP additions? Application of the ecological framework of (co‐)limitation by multiple resources

Beibei Ma, Xiaolong Zhou, Qi Zhang, Mingsen Qin, Linggang Hu, Kena Yang, Zhen Xie, Wenbin Ma, Beibei Chen, Huyuan Feng, Yongjun Liu, Guozhen Du, Xiaojun Ma & Xavier Le Roux
1.Nitrogen, N, and phosphorus, P, often limit biological processes in terrestrial ecosystems. Based on previous studies mainly focusing on plants, the concept of resource limitation has evolved towards a theory of (co)limitations by multiple‐resources. However, this ecological framework has not been applied to analyse how soil microorganisms and plants concurrently respond to N and/or P addition, and whether these responses are constrained by phylogenetic relatedness. 2.Here, we applied this framework to analyse microbial and plant...

Data from: Love them all: mothers provide care to foreign eggs in the European earwig Forficula auricularia

Sophie Van Meyel, Séverine Devers & Joël Meunier
The rejection of foreign individuals is considered a central parameter in the evolution of social life. Within family units, parents are typically thought to reject foreign offspring to ensure that their investment into care is directed towards their own descendants. Whereas selection for such kin bias is expected to be high when parental care is extended and involves numerous and energetically costly behaviours, it can be reduced when the acceptance of foreigners provide subsequent benefits...

Data from: Sperm competition accentuates selection on ejaculate attributes

Pauline Vuarin, Yves Hingrat, Loïc Lesobre, Michel Saint-Jalme, Frédéric Lacroix & Gabriele Sorci
Ejaculate attributes are important factors driving the probability of fertilizing eggs. When females mate with several males, competition between sperm to fertilize eggs should accentuate selection on ejaculate attributes. We tested this hypothesis in the North African houbara bustard (Chlamydotis undulata undulata) by comparing the strength of selection acting on two ejaculate attributes when sperm from single males or sperm from different males were used for insemination. In agreement with the prediction, we found that...

Data from: Are house sparrow populations limited by the lack of cavities in urbanized landscapes? an experimental test.

Frédéric Angelier & François Brischoux
Current urban policies are associated with deep changes in urban structures, which may impoverish urban biodiversity. A major concern is the disappearance of nesting sites for wild vertebrate species living in urban areas. New urban structures without any cracks or cavities may especially preclude cavity nesters from breeding in cities and they may cause population declines. In that context, we experimentally investigated this question in an urban exploiter bird species (the house sparrow, Passer domesticus),...

Data from: The global geography of fish diadromy modes

Anaïs Chalant, Céline Jézequel, Philippe Keith & Bernard Hugueny
Aim: Geographical gradients in resource production are likely to translate into macro-ecological patterns in the biodiversity of migratory organisms but few studies have addressed this question at a global scale. Here we tested a hypothesis based on uncoupled latitudinal gradients in marine and freshwater primary productivities aimed at explaining where (e. g. at which latitude) and at which stage of the life cycle (larvae: amphidromy, juvenile: catadromy, adult: anadromy) migration from ocean to freshwater occurs...

Data from: Local predation risk and matrix permeability interact to shape movement strategy

Laurane Winandy, Julien Cote, Lucie Di Gesu, Felix Pellerin, Audrey Trochet & Delphine Legrand
In fragmented landscapes, the reduced connectivity among patches drives the evolution of movement strategies through an increase of transience costs. Reduced movements may further alter heterogeneity in biotic and abiotic conditions experienced by individuals. The joint action of local conditions and matrix permeability may shape emigration decisions. Here, we tested the interactive effects of predation risk and matrix permeability on movement propensity, movement costs and movers’ phenotype in the common toad Bufo bufo. In a...

Data from: Genetic homogenization of indigenous sheep breeds in Northwest Africa

Ibrahim Belabdi, Abdessamad Ouhrouch, Mohamed Lafri, Semir Bechir Suheil Gaouar, Elena Ciani, Ahmed Redha Benali, Hakim Ould Ouelhadj, Abdelmajid Haddioui, François Pompanon, Véronique Blanquet, Dominique Taurisson-Mouret, Sahraoui Harkat, Johannes A. Lenstra, Badr Benjelloun & Anne Da Silva
Northwest-African sheep represent an ideal case-study for assessing the potential impact of genetic homogenization as a threat to the future of traditional breeds that are adapted to local conditions. We studied ten Algerian and Moroccan breeds of sheep, including three transboundary breeds, distributed over a large part of the Maghreb region, which represents a geographically and historically coherent unit. Our analysis of the dataset that involved carrying out Genome-wide SNP genotyping, revealed a high level...

Data from: Context-dependent signaling of coincident auditory and visual events in primary visual cortex

Thomas Deneux, Evan R. Harrell, Alexandre Kempf, Sebastian Ceballo, Anton Filipchuk & Brice Bathellier
Detecting rapid, coincident changes across sensory modalities is essential for recognition of sudden threats or events. Using two-photon calcium imaging in identified cell types in awake, head-fixed mice, we show that, among the basic features of a sound envelope, loud sound onsets are a dominant feature coded by the auditory cortex neurons projecting to primary visual cortex (V1). In V1, a small number of layer 1 interneurons gates this cross-modal information flow in a context-dependent...

Data from: The wing venation of the Protomyrmeleontidae (Insecta: Odonatoptera) reconsidered thanks to a new specimen from Molteno (Triassic; South Africa)

Isabelle Deregnaucourt, Torsten Wappler, John M. Anderson & Olivier Béthoux
Wing venation homologies of the Protomyrmeleontidae, a widespread group of damselfly-like stem-Odonata during the Triassic, are debated. The two main interpretations essentially disagree on the identification of RP branches. Indeed, Protomyrmeleontidae display a very complex wing venation necessarily involving, in a way or another, fusions of the concave RP branches with the convex intercalary veins. As a consequence, vein elevations in the radial area are challenging to interpret. Here, we present a new Triassic specimen...

Data from: Trade-offs in provisioning and stability of ecosystem services in agroecosystems

Daniel Montoya, Bart Haegeman, Sabrina Gaba, Claire De Mazancourt, Vincent Bretagnolle & Michel Loreau
Changes in land use generate trade-offs in the delivery of ecosystem services in agricultural landscapes. However, we know little about how the stability of ecosystem services responds to landscape composition, and what ecological mechanisms underlie these trade-offs. Here, we develop a model to investigate the dynamics of three ecosystem services in intensively-managed agroecosystems, i.e. pollination-independent crop yield, crop pollination, and biodiversity. Our model reveals trade-offs and synergies imposed by landscape composition that affect not only...

Data from: Transparency reduces predator detection in mimetic clearwing butterflies

Mónica Arias, Johanna Mappes, Charlotte Desbois, Swanne Gordon, Melanie McClure, Marianne Elias, Ossi Nokelainen & Doris Gomez
1. Predation is an important selective pressure and some prey have evolved conspicuous warning signals that advertise unpalatability (i.e. aposematism) as an antipredator defence. Conspicuous colour patterns have been shown effective as warning signals, by promoting predator learning and memory. Unexpectedly, some butterfly species from the unpalatable tribe Ithomiini possess transparent wings, a feature rare on land but common in water, known to reduce predator detection. 2. We tested if transparency of butterfly wings was...

Data from: Is telomere length a molecular marker of individual quality? insights from a long-lived bird

Frédéric Angelier, Henri Weimerskirch, Christophe Barbraud & Olivier Chastel
1. In wild vertebrates, some individuals survive and reproduce better than others and this has led to the concept of individual quality. Despite its importance when studying ecological processes and life-history trade-offs, measuring individual quality is complex because individuals must be followed during a large part of their life. 2. Recently, telomere biology has been successfully brought into ecology and telomere length has been suggested to be a promising molecular tool to evaluate individual quality...

Individual variation in age-dependent reproduction: fast explorers live fast but senesce young?

Niels Dingemanse, Maria Moiron, Yimen G. Araya-Ajoy, Alexia Mouchet & Robin N. Abbey-Lee
1. Adaptive integration of life history and behaviour is expected to result in variation in the pace-of-life. Previous work focused on whether “risky” phenotypes live-fast-but-die-young, but reported conflicting support. We posit that individuals exhibiting risky phenotypes may alternatively invest heavily in early-life reproduction but consequently suffer greater reproductive senescence. 2. We used a 7-year longitudinal dataset with >1200 breeding records of >800 female great tits assayed annually for exploratory behaviour to test whether within-individual age-dependency...
