Biases in Information Selection and Processing: Survey Evidence from the Pandemic

We conduct two survey experiments to study which information people choose to consume and how it affects their beliefs. In the first experiment, respondents choose between optimistic and pessimistic article headlines related to the COVID-19 pandemic and ar ...

A tool for mapping microglial morphology, morphOMICs, reveals brain-region and sex-dependent phenotypes

Kathryn Hess Bellwald, Lida Kanari, Martina Scolamiero

Environmental cues influence the highly dynamic morphology of microglia. Strategies to characterize these changes usually involve user-selected morphometric features, which preclude the identification of a spectrum of context-dependent morphological phenot ...

Male competition and the evolution of mating and ire-history traits in experimental populations of Aedes aegypti

Brian Dennis Hollis

Aedes aegypti is an important disease vector and a major target of reproductive control efforts. We manipulated the opportunity for sexual selection in populations of Ae. aegypti by controlling the number of males competing for a single female. Populations ...

Sexual conflict drives male manipulation of female postmating responses in Drosophila melanogaster

Laurent Keller, Brian Dennis Hollis

In many animals, females respond to mating with changes in physiology and behavior that are triggered by molecules transferred by males during mating. In Drosophila melanogaster, proteins in the seminal fluid are responsible for important female postmating ...

Sexual selection shapes development and maturation rates in Drosophila

Laurent Keller, Brian Dennis Hollis

Explanations for the evolution of delayed maturity usually invoke trade-offs mediated by growth, but processes of reproductive maturation continue long after growth has ceased. Here, we tested whether sexual selection shapes the rate of posteclosion matura ...

Location choice with longitudinal WiFi data

Michel Bierlaire, Matthieu Marie Cochon de Lapparent, Antonin Danalet, Loïc Tinguely

Location-aware data collection technologies provide new insights about location choices. Only a few dynamic models of location choice exist in scientific literature. To our knowledge, none of them correct for serial correlation. In this paper, we model cho ...

Melanic color-dependent antipredator behavior strategies in barn owl nestlings

Xavier Falourd

The arms race between predators and prey has led to morphological and behavioral adaptations. Different antipredator strategies can coexist within a population if each strategy is the result of a trade-off with competing demands. Antipredator behavior can ...

Positive feedback in the transition from sexual reproduction to parthenogenesis

Séverine Vuilleumier Varisco

Understanding how new phenotypes evolve is challenging because intermediate stages in transitions from ancestral to derived phenotypes often remain elusive. Here we describe and evaluate a new mechanism facilitating the transition from sexual reproduction ...

Task-dependent influence of genetic architecture and mating frequency on division of labour in social insect societies

Dario Floreano, Laurent Keller

Division of labour is one of the most prominent features of social insects. The efficient allocation of individuals to different tasks requires dynamic adjustment in response to environmental perturbations. Theoretical models suggest that the colony-level ...

Conserved oviposition preferences in alpine leaf beetle populations despite host shifts and isolation

Anthony Christopher Davison

Choosing the plant on which to lay their eggs is the last act of care that most female herbivorous insects bestow upon their offspring. These decisions play a pivotal role in insect–plant interactions, placing host preference under strong selection and ...
