Journal ArticleDOI
On the origin of species by sympatric speciation
Ulf Dieckmann,Michael Doebeli +1 more
TL;DR: This work uses multilocus genetics to describe sexual reproduction in an individual-based model and considers the evolution of assortative mating, which leads to reproductive isolation between ecologically diverging subpopulations and conforms well with mounting empirical evidence for the sympatric origin of many species.
Journal ArticleDOI
Decoupling function and taxonomy in the global ocean microbiome
TL;DR: It is found that environmental conditions strongly influence the distribution of functional groups in marine microbial communities by shaping metabolic niches, but only weakly influence taxonomic composition within individual functional groups.
Journal ArticleDOI
Spatial structure often inhibits the evolution of cooperation in the snowdrift game
Christoph Hauert,Michael Doebeli +1 more
TL;DR: In this article, it was shown that spatial structure reduces the proportion of cooperators for a wide range of parameters in unstructured snowdrift games, and in particular, spatial structure eliminates cooperation if the cost-to-benefit ratio of cooperation is high.
Journal ArticleDOI
Function and functional redundancy in microbial systems
Stilianos Louca,Martin F. Polz,Florent Mazel,Florent Mazel,Michaeline B. N. Albright,Julie A. Huber,Mary I. O'Connor,Martin Ackermann,Martin Ackermann,Aria S. Hahn,Diane S. Srivastava,Sean A. Crowe,Michael Doebeli,Laura Wegener Parfrey +13 more
TL;DR: Both patterns are unlikely to be the result of ecological drift, but are inevitable emergent properties of open microbial systems resulting mainly from biotic interactions and environmental and spatial processes.
Journal ArticleDOI
Speciation along environmental gradients
Michael Doebeli,Ulf Dieckmann +1 more
TL;DR: It is shown that along an environmental gradient, evolutionary branching can occur much more easily than in non-spatial models, and this facilitation is most pronounced for gradients of intermediate slope.
