Накратко на български
Връзката между микроеволюцията при популации от триезисти колюшки и макроеволюцията при различни видове риби се анализира чрез модели и генетични данни. Това помага да се разбере как се появява биоразнообразието и как еволюцията протича в различни времеви мащаби.

Bridging MICroevolution and MACroevolution in sticklebacks
The MICMAC project aimed at better understanding the emergence of biodiversity by studying the links between microevolutionary mechanisms (at the population level) and macroevolutionary patterns (at the species level). Those two scales are often studied by different communities of researchers, using different tools and this is a major problem to study the evolutionary process as a continuum. A major goal of the project was study the link between those two scales, both theoretically (using models and simulations) and empirically with fishes as a model system (three-spined sticklebacks at microevolutionary scale and other species of fish at the macroevolutionary scale). I performed the research in the Schluter lab at the University of British Columbia in Canada during 17 months to build a general framework that could permit to understand how evolution unfolds from shallow to deep time scales. This work lead to the publication of 3 articles in high impact journal, and the organization of a workshop on the link between micro- to macroevolution. I have also generated a unique dataset with ~650 whole genome sequences across the Pacific and the Atlantic oceans for future work on stickleback evolution.

Цел на проекта
How is biodiversity generated? What are the main factors affecting the emergence of biodiversity and its evolution? To answer these questions, since more than one century, evolutionary biologists have been studying life with two separated approaches: either population biologists tend to study evolution of individuals and divergence of populations below the species level (microevolution), or paleontologists and phylogeneticists are studying the diversification and the extinction of species at a much coarser scale (macroevolution). Only extremely rare studies have permitted to make the link between micro and macroevolution and an integrative approach bridging the two scales is currently lacking. In this project, I propose to study the factors affecting the diversification process (speciation and extinction) and phenotypic evolution (morphology and ecological niche) at the two different evolutionary scales using two datasets: (i) a completely new dataset of 300 three- spined stickleback genomes distributed in more than 100 populations in North America and (ii) a much broader dataset encompassing genomes for each species of the Gasterosteidae family (including sticklebacks) permitting to reconstruct the relationships between species. This project will be composed by two distinct phases: the first phase consists in generating genomic sequences with Next Generation Sequencing and running microevolution analyses with D. Schluter in University of British Colombia (Vancouver, Canada); and the second phase will permit to build a new theoretical integrative framework permitting to explain the bridges between micro and macroevolution with N. Salamin in University of Lausanne (Switzerland). My aim is to strongly stimulate the interactions between the different communities of researchers in evolution, and to promote evolutionary research to a broader audience through public talks in museums and primary/secondary schools.
