Experimental evolution of slowed cognitive aging in Drosophila melanogaster

Reproductive output and cognitive performance decline in parallel during aging, but it is unknown whether this reflects a shared genetic architecture or merely the declining force of natural selection acting independently on both traits. We used experiment ...

Determining the Surface Structure of Silicated Alumina Catalysts via Isotopic Enrichment and Dynamic Nuclear Polarization Surface-Enhanced NMR Spectroscopy

David Lyndon Emsley, Brennan James Walder, Jasmine Viger-Gravel

Isotopic enrichment of Si-29 and DNP-enhanced NMR spectroscopy are combined to determine the detailed surface structure of a silicated alumina catalyst. The significant sensitivity enhancement provided by DNP is vital to the acquisition of multinuclear and ...

Increasing the Sensitivity to Short-Lived Species in a Modulated Excitation Experiment

Davide Ferri, Oliver Kröcher, Alexander Wokaun

The combination of spectroscopic and diffraction methods to study chemical transformations is fundamental for the understanding of reaction mechanisms. The identification of short-lived species, likely active species, is often hindered by the contribution ...

New Techniques for Ancient Proteins: Direct Coupling Analysis Applied on Proteins Involved in Iron Sulfur Cluster Biogenesis

Paolo De Los Rios, Duccio Malinverni

Direct coupling analysis (DCA) is a powerful statistical inference tool used to study protein evolution. It was introduced to predict protein folds and protein-protein interactions, and has also been applied to the prediction of entire interactomes. Here, ...

Separating sources of density-dependent and density-independent establishment limitation in invading species

Pierre Rémi Mariotte

Successful colonization by invasive species depends on both the ability to disperse seeds to a site and an ability to establish once seeds have arrived. While seed and establishment limitation are known to jointly influence colonization, decomposing establ ...

Neuronal Representation of Social Information in the Medial Amygdala of Awake Behaving Mice

Alexander Mathis

The medial amygdala (MeA) plays a critical role in processing species- and sex-specific signals that trigger social and defensive behaviors. However, the principles by which this deep brain structure encodes social information is poorly understood. We used ...

Detecting and Quantifying Changing Selection Intensities from Time-Sampled Polymorphism Data

Jeffrey David Jensen, Matthieu Foll, Sebastian Matuszewski, Stefan Jean Laurent, Hyunjin Shim

During his well-known debate with Fisher regarding the phenotypic dataset of Panaxia dominula, Wright suggested fluctuating selection as a potential explanation for the observed change in allele frequencies. This model has since been invoked in a number of ...

The Impact of Linked Selection in Chimpanzees: A Comparative Study

Jeffrey David Jensen, Susanne Petra Pfeifer

Levels of nucleotide diversity vary greatly across the genomes of most species owing to multiple factors. These include variation in the underlying mutation rates, as well as the effects of both direct and linked selection. Fundamental to interpreting the ...

Ecological strategies in stable and disturbed environments depend on species specialisation

Séverine Vuilleumier Varisco

Ecological strategies are integral to understanding species survival in different environments. However, how habitat specialisation is involved in such strategies is not fully understood, particularly in heterogeneous and disturbed environments. Here, we s ...

Can multi-generational exposure to ocean warming and acidification lead to the adaptation of life-history and physiology in a marine metazoan?

Emma Mary Gibbin, Félix Christen

Ocean warming and acidification are concomitant global drivers that are currently threatening the survival of marine organisms. How species will respond to these changes depends on their capacity for plastic and adaptive responses. Little is known about th ...
