Data from: The impact of insecticide resistance on Culex pipiens immunity

Julien Vézilier, Antoine Nicot, Julien De Lorgeril, Sylvain Gandon & Ana Rivero
Because of their role as vectors of diseases, the evolution of insecticide resistance in mosquitoes has been intensively investigated. Insecticide resistance is associated to a wide range of pleiotropic effects on several key life history traits of mosquitoes such as longevity and behavior. However, despite its potential implications in pathogen transmission, the effects of insecticide resistance on mosquito immunity have received little, if any, attention. Here, we investigate the impact of insecticide resistance in Culex...

Data from: Evolutionary history of almond tree domestication in the Mediterranean basin

Malou Delplancke, Nadir Alvarez, Laure Benoit, Maria Anahi Espindola, Helene I. Joly, Samuel Neuenschwander & Nils Arrigo
Genetic diversity of contemporary domesticated species is shaped by both natural and human-driven processes. However, until now, little is known about how domestication has imprinted the variation of fruit tree species. In this study, we reconstruct the recent evolutionary history of the domesticated almond tree, Prunus dulcis, around the Mediterranean Basin, using a combination of nuclear and chloroplast microsatellites (i.e. SSRs) to investigate patterns of genetic diversity. Whereas conservative chloroplast SSRs show a widespread haplotype...

Data from: The distribution of mutational fitness effects of phage ϕX174 on different hosts

Pedro F. Vale, Marc Choisy, Rémy Froissart, Rafael Sanjuán & Sylvain Gandon
Adaptation depends greatly on the distribution of mutation fitness effects (DMFE), but the phenotypic expression of mutations is often environment-dependent. The environments of multi-host pathogens are mostly governed by their hosts and therefore measuring the DMFE on multiple hosts can inform on the likelihood of short-term establishment and longer-term adaptation of emerging pathogens. We explored this by measuring the growth rate of 36 mutants of the lytic bacteriophage ϕX174 on two host backgrounds, Escherichia coli...

Data from: Phenotypic stochasticity prevents lytic bacteriophage population from extinction during bacterial stationary phase

Romain Gallet, Thomas Lenormand & Ing Nang Wang
It is generally thought that the adsorption rate of a bacteriophage correlates positively with fitness, but this view neglects that most phages rely only on exponentially growing bacteria for productive infections. Thus, phages must cope with the environmental stochasticity that is their hosts’ physiological states. If lysogeny is one alternative, it is unclear how strictly lytic phages can survive the host stationary phase. Three scenarios may explain their maintenance: (1) pseudolysogeny, (2) diversified or (3)...

Data from: Digging through model complexity: using hierarchical models to uncover evolutionary processes in the wild

Mathieu Buoro, Etienne Prévost & Olivier Gimenez
The growing interest for studying questions in the wild requires acknowledging that eco-evolutionary processes are complex, hierarchically structured and often partially observed or with measurement error. These issues have long been ignored in evolutionary biology, which might have led to flawed inference when addressing evolutionary questions. Hierarchical modelling (HM) has been proposed as a generic statistical framework to deal with complexity in ecological data and account for uncertainty. However, to date, HM has seldom been...

Data from: Habitat-linked population genetic differentiation in the Blue tit Cyanistes caeruleus

Melody Porlier, Dany Garant, Philippe Perret & Anne Charmantier
Although the recent emergence of the field of landscape genetics has led to several studies investigating the effects of habitat composition between populations on genetic differentiation, much less is known on the impact of within-habitat ecological characteristics on levels of gene flow and genetic differentiation among populations. Using data on 840 individuals sampled in 8 sites in Corsica and 1 in southern France and analyzed at 10 microsatellite loci, we assessed the spatial and temporal...

Data from: Morphological, ecological and genetic aspects associated with endemism in the Fly Orchid group

Yann Triponez, Nils Arrigo, Loïc Pellissier, Bertrand Schatz & Nadir Alvarez
The European genus Ophrys (Orchidaceae) is famous for its insect-like floral morphology, an adaptation for a pseudocopulatory pollination strategy involving Hymenoptera males. A large number of endemic Ophrys species have recently been described, especially within the Mediterranean Basin, which is one of the major species diversity hotspots. Subtle morphological variation and specific pollinator dependence are the two main perceptible criteria for describing numerous endemic taxa. However, the degree to which endemics differ genetically remains a...
