The adaptive significance of adjusting behavioural activities to the right time of the day is intuitive. Laboratory studies have implicated an important role of circadian clocks in behavioural timing and rhythmicity. Yet, recent studies on clock-mutant animals questioned this importance under more naturalistic settings, as various clock mutants showed nearly normal diel activity rhythms under semi-natural Zeitgeber conditions. We here report evidence that proper timing of eclosion, a vital behav...

It is assumed that a properly timed circadian clock enhances fitness, but only few studies have truly demonstrated this in animals. We raised each of the three classical Drosophila period mutants for >50 generations in the laboratory in competition with wildtype flies. The populations were either kept under a conventional 24-h day or under cycles that matched the mutant’s natural cycle, i.e. a 19-h day in the case of pers mutants and a 29-h day for perl mutants. The arrhythmic per0 mutants were ...

The life cycle of many social insects living in seasonal environments is characterized by a period of (pure) investment into worker brood followed by a phase of pure allocation of resources to the production of sexuals. Researchers have invested some effort to find possible correlates (proximate triggers) of this transition but current empirical knowledge does not provide clear evidence. Utilizing an established theoretical model—modified to account for brood developmental time—we show that a st...

Background Many species are shifting their ranges in response to global climate change. Range expansions are known to have profound effects on the genetic composition of populations. The evolution of dispersal during range expansion increases invasion speed, provided that a species can adapt sufficiently fast to novel local conditions. Genetic diversity at the expanding range border is however depleted due to iterated founder effects. The surprising ability of colonizing species to adapt to nove...

Simultaneous progressive provisioners feed their offspring gradually as they develop-and typically feed more than one offspring simultaneously (SIM) at a time. In contrast, "sequential mass provisioners" supply offspring one after another (SEQ). Utilizing individual-based simulations, Field (Nature 404: 869-871, 2005) compared the lifetime reproductive success of these strategies in different scenarios. Accordingly, SEQ should evolve in the majority of cases-SIM only has an evolutionary benefit ...

Theory predicts that males and females should often join the mating pool at different times (sexual dimorphism in timing of emergence [SDT]) as the degree of SDT affects female mating success. We utilize an analytical model to explore (1) how important SDT is for female mating success, (2) how mating success might change if either sex's mortality (abruptly) increases, and (3) to what degree evolutionary responses in SDT may be able to mitigate the consequences of such mortality increase. Increas...
