In Nature microbial populations are subject to fluctuating nutrient levels. Nutrient abundance fluctuations are important for evolutionary and ecological dynamics in microbial communities since they impact growth rates, population sizes and microbial physiology. Here we use automated continuous-culture devices and single-cell imaging to show that when populations of Escherichia coli are subject...

The dispersal ability of a species will be critical for how population dynamics are realized in spatially structured systems. To date, the effect of group dispersal on metapopulation dynamics is poorly understood. Here, we investigate how group dispersal and Allee effects shape metapopulation dynamics identifying conditions in which group dispersal can be an advantage over independent dispersal...

Group size is an important variable describing behavioural ecology of animals. A variety of factors such as habitat characteristics, life history, spatio-temporal resource dynamics, population density, predation risk, competition with kin, and social learning often determine group size in large mammals. We studied temporal dynamics of group size in Siberian Ibex (Capra sibirica) in a protected ...

Information on genetic variation within and among populations of highly mobile organisms such as seabirds is necessary for understanding their evolution and ecology, and can be a tool for conservation. Recent developments in molecular genetics, including efficient mutationdetection methods and automated sequencing, are providing detailed genetic information for non-model organisms. Furthermore,...
