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

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 ...

No Scope for Social Modulation of Steroid Levels in a Year-Round Territorial Damselfish

Katarina Damjanovic

Both latitude and mating system have been proposed to shape relationships between steroid hormone levels and social behavior. Recently it has been postulated that species with long lasting non-seasonal territorial behavior have low androgen responsiveness. ...

Wiley-Blackwell2015

Major climatic and geological events but also population history (secondary contacts) have generated cycles of population isolation and connection of long and short periods. Recent empirical and theoretical studies suggest that fast evolutionary processes ...

Evolution of uni- and bifactorial sexual compatibility systems in fungi

Séverine Vuilleumier Varisco

Mating systems, that is, whether organisms give rise to progeny by selfing, inbreeding or outcrossing, strongly affect important ecological and evolutionary processes. Large variations in mating systems exist in fungi, allowing the study of their origin an ...

Transitions from reproductive systems governed by two self-incompatible loci to one in fungi

Séverine Vuilleumier Varisco

Self-incompatibility (SI), a reproductive system broadly present in plants, chordates, fungi, and protists, might be controlled by one or several multiallelic loci. How a transition in the number of SI loci can occur and the consequences of such events for ...

The role of Schizosaccharomyces pombe dma1 in spore formation during meiosis

Viesturs Simanis, Andrea Krapp, Elena Cano

Meiosis is a specialised form of the cell cycle that gives rise to haploid gametes. In Schizosaccharomyces pombe, the products of meiosis are four spores, which are formed by encapsulation of the four meiosis II nuclei within the cytoplasm of the zygote pr ...

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 ...

RAP-1 factor is necessary for DNA loop formation in vitro at the silent mating type locus HML

Thierry Laroche

DNA fragments containing the silencers that flank the mating type genes at HML alpha are shown to bind specifically to the nuclear scaffold of yeast. The scaffold proteins are solubilized with urea and then renatured to form a soluble extract which allows ...
