Data from: Nonlinear phenotypic variation uncovers the emergence of heterosis in Arabidopsis thaliana

François Vasseur, Louise Fouqueau, Dominique De Vienne, Thibault Nidelet, Cyrille Violle & Detlef Weigel
Heterosis describes the phenotypic superiority of hybrids over their parents in traits related to agronomic performance and fitness. Understanding and predicting nonadditive inheritance such as heterosis is crucial for evolutionary biology as well as for plant and animal breeding. However, the physiological bases of heterosis remain debated. Moreover, empirical data in various species have shown that diverse genetic and molecular mechanisms are likely to explain heterosis, making it difficult to predict its emergence and amplitude...

1. The identification of geographic areas where the densities of animals are highest across their annual cycles is a crucial step in conservation planning. In marine environments, however, it can be particularly difficult to map the distribution of species, and the methods used are usually biased towards adults, neglecting the distribution of other life-history stages even though they can represent a substantial proportion of the total population. 2. Here we develop a methodological framework for...

Data from: Individual differences in behaviour explain variation in survival: a meta-analysis

Maria Moiron, Kate Laskowski & Petri Niemelä
Research focusing on among-individual differences in behaviour (“animal personality”) has been blooming for over a decade. One of the central theories explaining the maintenance of such behavioural variation posits that individuals expressing greater “risky” behaviours should suffer higher mortality. Here, for the first time, we synthesize the existing empirical evidence for this key prediction. Our results did not support this prediction as there was no directional relationship between riskier behaviour and greater mortality; however there...

Identifying stationary phases in multivariate time series for highlighting behavioural modes and home range settlements

Rémi Patin, Marie-Pierre Etienne, Emilie Lebarbier, Simon Benhamou & Simon Chamaillé‐Jammes
1. Recent advances in bio-logging open promising perspectives in the study of animal movements at numerous scales. It is now possible to record time-series of animal locations and ancillary data (e.g. activity level derived from on-board accelerometers) over extended areas and long durations with a high spatial and temporal resolution. Such time-series are often piecewise stationary, as the animal may alternate between different stationary phases (i.e. characterised by a specific mean and variance of some...

Manipulation of photoperiod perception advances gonadal growth but not laying date in the great tit

Lucia Salis, Samuel Caro, Roelof A. Hut, Louis Vernoij & Marcel E. Visser
In seasonal environments, organisms use biotic and abiotic cues to time various biological processes that are crucial for growth, survival and reproductive success. Photoperiod is the best-known cue used to regulate gonadal development, migration and moult of many animal species. In birds, the relationship between photoperiod and gonadal development is clearly established, but we have little understanding on whether photoperiod also regulates actual timing of egg laying under natural conditions. Elucidating the link between photoperiod...

Data from: Data gaps and opportunities for comparative and conservation biology

Biodiversity loss is a major challenge. Over the past century, the average rate of vertebrate extinction has been about 100-fold higher than the estimated background rate and population declines continue to increase globally. Birth and death rates determine the pace of population increase or decline, thus driving the expansion or extinction of a species. Design of species conservation policies hence depends on demographic data (e.g., for extinction risk assessments or estimation of harvesting quotas). However,...

Data from: Multiple parapatric pollinators have radiated across a continental fig tree displaying clinal genetic variation

Hui Yu, Enwei Tian, Linna Zheng, Xiaoxia Deng, Yufen Cheng, Lianfu Chen, Wei Wu, Wattana Tanming, Dayong Zhang, Stephen G. Compton & Finn Kjellberg
The ways that plant-feeding insects have diversified is central to our understanding of terrestrial ecosystems. Obligate nursery pollination mutualisms provide highly relevant model systems of how plants and their insect associates have diversified and the over 800 species of fig trees (Ficus) allow comparative studies. Fig trees can have one or more pollinating fig wasp species (Agaonidae) that breed within their figs, but factors influencing their number remain to be established. In some widely distributed...

Data from: A dynamic model of facilitation on environmental stress gradients

Olivier Dangles
Theories based on competition for resources in animals and other non-sessile organisms rarely consider the role of facilitative interactions. Yet these interactions are important for community assembly, especially under stressful environments (e.g. the stress-gradient hypothesis, SGH). To make an explicit link between species interaction theory and SGH patterns, I used a classic resource competition model promoting coexistence between a beneficiary and its facilitator sharing a common resource along a stress gradient. I compared model outcomes...

Data from: Flower phenology as a disruptor of the fruiting dynamics in temperate oak species

Eliane Schermer, Marie-Claude Bel-Venner, Jean-Michel Gaillard, Stéphane Dray, Vincent Boulanger, Iris Le Roncé, Gilles Oliver, Isabelle Chuine, Sylvain Delzon & Samuel Venner
Many perennial plants display masting, i.e., fruiting with strong interannual variations, irregular and synchronized between trees within the population. Here, we tested the hypothesis that the early flower phenology in temperate oak species promotes stochasticity into their fruiting dynamics, which could play a major role in tree reproductive success. From large field monitoring network, we compared the pollen phenology between temperate and Mediterranean oak species. Then, focusing on temperate oak species, we explored the influence...

Data from: Consequences of past and present harvest management in a declining flyway population of common eiders Somateria mollissima

Rune Tjørnløv, Roger Pradel, Remi Choquet, Thomas Kjær Christensen & Morten Frederiksen
1. Harvested species population dynamics are shaped by the relative contribution of natural and harvest mortality. Natural mortality is usually not under management control, so managers must continuously adjust harvest rates to prevent overexploitation. Ideally, this requires regular assessment of the contribution of harvest to total mortality and how this affects population dynamics. 2. To assess the impact of hunting mortality on the dynamics of the rapidly declining Baltic/Wadden Sea population of common eiders Somateria...

Data from: Males’ calls carry information about individual identity and morphological characteristics of the caller in burrowing petrels

Charlène Gémard
We took morphometric measurements on males of two burrowing petrel species: blue petrel Halobaena caerulea ("BP") and Antarctic prion Pachyptila desolata ("AP"). We also provoked them with a playback and measured acoustic parameters on their provoked calls. Fieldwork was performed in a small sub-Antarctic island (Ile Verte, 49°51′S, 70°05′E) of the Kerguelen Archipelago, in the southern Indian Ocean, where blue petrels and the during the 2017 and 2018 birds’ incubation period (25 November 2017 to...

Data from: Transparency improves concealement in cryptically coloured moths

Mónica Arias, Marianne Elias, Christine Andraud, Serge Berthier & Doris Gomez
Predation is a ubiquitous and strong selective pressure on living organisms. Transparency is a predation defence widespread in water but rare on land. Some Lepidoptera display transparent patches combined with already cryptic opaque patches. A recent study showed that transparency reduced detectability of aposematic prey with conspicuous patches. However, whether transparency has any effect at reducing detectability of already cryptic prey is still unknown. We conducted field predation experiments with free avian predators where we...

Data from: RAD‐sequencing for estimating genomic relatedness matrix‐based heritability in the wild: a case study in roe deer

Laura Gervais, Charles Perrier, Maria Bernard, Joël Merlet, Josephine M. Pemberton, Benoit Pujol & Erwan Quemere
Estimating the evolutionary potential of quantitative traits and reliably predicting responses to selection in wild populations are important challenges in evolutionary biology. The genomic revolution has opened up opportunities for measuring relatedness among individuals with precision, enabling pedigree-free estimation of trait heritabilities in wild populations. However, until now, most quantitative genetic studies based on a genomic relatedness matrix (GRM) have focused on long-term monitored populations for which traditional pedigrees were also available, and have often...
