Data from: UV wavelengths experienced during development affect larval newt visual sensitivity and predation efficiency

Mélissa Martin, Marc Théry, Gwendolen Rodgers, Delphine Goven, Stéphane Sourice, Pascal Mège & Jean Secondi
We experimentally investigated the influence of developmental plasticity of ultraviolet (UV) visual sensitivity on predation efficiency of the larval smooth newt, Lissotriton vulgaris. We quantified expression of SWS1 opsin gene (UV-sensitive protein of photoreceptor cells) in the retinas of individuals who had developed in the presence (UV+) or absence (UV−) of UV light (developmental treatments), and tested their predation efficiency under UV+ and UV− light (testing treatments). We found that both SWS1 opsin expression and...

Data from: High-throughput microsatellite genotyping in ecology: improved accuracy, efficiency, standardization and success with low-quantity and degraded DNA

Marta De Barba, Christian Miquel, Stephane Lobreaux, Pierre Yves Quenette, Jon E. Swenson & Pierre Taberlet
Microsatellite markers have played a major role in ecological, evolutionary and conservation research during the past 20 years. However, technical constrains related to the use of capillary electrophoresis and a recent technological revolution that has impacted other marker types have brought to question the continued use of microsatellites for certain applications. We present a study for improving microsatellite genotyping in ecology using high-throughput sequencing (HTS). This approach entails selection of short markers suitable for HTS,...

Data from: Background selection in partially selfing populations

Denis Roze
Self-fertilizing species often present lower levels of neutral polymorphism than their outcrossing relatives. Indeed, selfing automatically increases the rate of coalescence per generation, but also enhances the effects of background selection and genetic hitchhiking by reducing the efficiency of recombination. Approximations for the effect of background selection in partially selfing populations have been derived previously assuming tight linkage between deleterious alleles and neutral loci. However, loosely linked deleterious mutations may have important effects on neutral...

Data from: Detection of invasive mosquito vectors using environmental DNA (eDNA) from water samples

Judith Schneider, Alice Valentini, Tony Dejean, Fabrizio Montarsi, Pierre Taberlet, Olivier Glaizot & Luca Fumagalli
Repeated introductions and spread of invasive mosquito species (IMS) have been recorded on a large scale these last decades worldwide. In this context, members of the mosquito genus Aedes can present serious risks to public health as they have or may develop vector competence for various viral diseases. While the Tiger mosquito (Aedes albopictus) is a well-known vector for e.g. dengue and chikungunya viruses, the Asian bush mosquito (Ae. j. japonicus) and Ae. koreicus have...

Data from: How social network structure affects decision-making in Drosophila melanogaster

Cristian Pasquaretta, Marine Battesti, Elizabeth Klenschi, Christophe A. H. Bousquet, Cedric Sueur & Frederic Mery
Animals use a number of different mechanisms to acquire crucial information. During social encounters animals can pass information from one to another but, ideally, they would only use information that benefits survival and reproduction. Therefore, individuals need to be able to determine the value of the information they receive. One cue can come from the behaviour of other individuals that are already using the information. Here we study how individual decision-making is influenced by the...

Data from: Genetic variation in aggregation behaviour and interacting phenotypes in Drosophila

Anne Sophie Philippe, Raphael Jeanson, Cristian Pasquaretta, Francois Rebaudo, Cedric Sueur & Frederic Mery
Aggregation behaviour is the tendency for animals to group together which may have important consequences on individual fitness. We used a combination of experimental and simulation approaches to study how genetic variation and social environment interact to influence aggregation dynamics in Drosophila. To do this, we use two different natural lines of Drosophila that arise from a polymorphism in the foraging gene (“rovers” and “sitters”). We placed groups of flies in a heated arena. Flies...
