Supplementary information for: Redundancy analysis, genome-wide association studies, and the pigmentation of brown trout (Salmo trutta L.)

Bruno Guinand, Théo Valette, Maeva Leitwein, Erick Desmarais, Patrick Berrebi & Jean-Marc Lascaux
The association of molecular variants to phenotypic variation is a main issue in biology, often tackled with genome-wide association studies (GWAS). GWAS are challenging, with increasing, but still limited use in evolutionary biology. We used redundancy analysis (RDA) as a complimentary ordination approach to single- and multi-trait GWAS to explore the molecular basis of pigmentation variation in brown trout (Salmo trutta) belonging to wild populations impacted by hatchery fish. Based on 75,684 single nucleotide polymorphic...

Mother-to-daughter transmission of hygiene in mandrills

Clemence Poirotte & Marie Charpentier
Social animals are particularly exposed to infectious diseases. Pathogen-driven selection pressure has thus favoured the evolution of behavioural adaptations to decrease transmission risk, such as “social distancing”. Yet, such strategy might deprive individuals from valuable social interactions, generating a cost-benefit trade-off between pathogen avoidance and social opportunities. Recent studies revealed that hosts differ in the expression of these behavioural defences but the determinants driving such inter-individual variation remain poorly understood. Using 5 years of detailed...

Genotypic sex shapes maternal care in the African Pygmy mouse, Mus minutoides

Louise Heitzmann, Marie Challe, Julie Pérez, Laia Castell, Evelyne Galibert, Agnes Martin, Emmanuel Valjent & Frederic Veyrunes
Sexually dimorphic behaviours, such as parental care, have long been thought to be driven mostly, if not exclusively, by gonadal hormones. In the past two decades, a few studies have challenged this view, highlighting the direct influence of the sex chromosome complement (XX vs XY or ZZ vs ZW). The African pygmy mouse, Mus minutoides, is a wild mouse species with naturally occurring XY sex reversal induced by a third, feminizing X* chromosome, leading to...

Data and code from: Multiple sex chromosome drivers in a mammal with three sex chromosomes

Paul Saunders, Julie Perez, Ophélie Ronce & Frédéric Veyrunes
Eukaryotes with separate males and females display a great diversity in the way they determine sex, but it is still unclear what evolutionary forces cause transitions between sex-determining systems. Rather that the lack of hypotheses, the problem is the scarcity of adequate biological systems to test them. Here, we take advantage of the recent evolution of a feminizing X chromosome (called X*) in the African pygmy mouse Mus minutoides, to investigate one of the evolutionary...

Evolutionary determinants of non-seasonal breeding in wild chacma baboons

Jules Dezeure, Lugdiwine Burtschell, Alice Baniel, Alecia J. Carter, Bernard Godelle, Cowlishaw Guy & Huchard Elise
Animal reproductive phenology varies from strongly seasonal to non-seasonal, sometimes among closely related or sympatric species. While the extent of reproductive seasonality is often attributed to environmental seasonality, this fails to explain many cases of non-seasonal breeding in seasonal environments. We investigated the evolutionary determinants of non-seasonal breeding in a wild primate, the chacma baboon (Papio ursinus), living in a seasonal environment with high climatic unpredictability. We tested three hypotheses proposing that non-seasonal breeding has...

Mandrill mothers associate with infants who look like their own offspring using phenotype matching

Marie Charpentier, Clémence Poirotte, Berta Roura-Torres, Paul Amblard-Rambert, Eric Willaume, Peter Kappeler, François Rousset & Julien Renoult
Behavioral discrimination of kin is a key process structuring social relationships in animals. In this study, we provide a first example of discrimination towards non-kin by third-parties through a mechanism of phenotype matching. In mandrills, we recently demonstrated increased facial resemblance among paternally-related juvenile and adult females indicating adaptive opportunities for paternal kin recognition. Here, we hypothesize that mothers use offspring’s facial resemblance with other infants to guide offspring’s social opportunities towards similarly-looking ones. Using...

Data from: A phylogenetic study to assess the link between biome specialisation and diversification in swallowtail butterflies

Sara Gamboa, Fabien L. Condamine, Juan L. Cantalapiedra, Sara Varela, Jonathan Pelegrín, Iris Menéndez, Fernando Blanco & Manuel Hernández Fernández
The resource-use hypothesis, proposed by E.S. Vrba, states that habitat fragmentation caused by climatic oscillations would affect particularly biome specialists (species inhabiting only one biome), which might show higher speciation and extinction rates than biome generalists. If true, lineages would accumulate biome-specialist species. This effect would be particularly exacerbated for biomes located at the periphery of the global climatic conditions, namely, biomes that have high/low precipitation and high/low temperature such as rainforest (warm-humid), desert (warm-dry),...

Social-environmental index: Combining social and biophysical indicators reveals limits to growth

Stanislas Rigal
The negative impact of the dominant socio-economic paradigm on the biosphere, on the climate, and on societies themselves are acute. Yet, the success of countries is measured by indicators known to be limited because they target a socially attractive but environmentally unsustainable model of society. A myriad of indicators have been proposed to address this lack of relevant measurements that assess the real social achievements of countries. At the same time, the impacts of human...

Estimating the extended and hidden species diversity from environmental DNA in hyper-diverse regions

Jean-Baptiste Juhel, Virginie Marques, Rizkie Utama, Indra Vimono, Hagi Sugeha, Kadarusman Kadarusman, Christophe Cochet, Tony Dejean, Andrew Hoey, David Mouillot, Régis Hocdé & Laurent Pouyaud
Species inventories are the building blocks of our assessment of biodiversity patterns and human impact. Yet, historical inventories based on visual observations are often incomplete impairing subsequent analyses of ecological mechanisms, extinction risk and management success. Environmental DNA (eDNA) metabarcoding is an emerging tool that can provide wider biodiversity assessments than classical visual-based surveys. However, eDNA-based inventories remain limited by sampling effort and reference database incompleteness. In this study, we propose a new framework coupling...

Data for: Limited host availability disrupts the genetic correlation between virulence and transmission

Diogo P. Godinho, Leonor R. Rodrigues, Sophie Lefevre, Laurane Delteil, André F. Mira, Inês R. Fragata, Sara Magalhães & Alison B. Duncan
Virulence is expected to be linked to parasite fitness via transmission. However, it is not clear whether this relationship is genetically determined, nor if it differs when transmission occurs continuously during, or only at the end of, the infection period. Here, we used inbred lines of the macro-parasitic spider mite Tetranychus urticae to disentangle genetic vs non-genetic correlations among traits, while varying parasite density and opportunities for transmission. A positive genetic correlation between virulence and...
