Накратко на български

Динамиката на видовото разнообразие се анализира чрез генетични и географски данни, като например защо в Европа и Северна Америка днес се появяват нови видове по-бързо. Това помага за определяне на приоритетите при опазването на природата и прогнозирането на ефектите от глобалните промени.

Evolutionary diversification across scales

The project investigates the dynamics of species diversity. Number of species has been argued to accumulate across regions and taxa at constant, accelerating or decelerating rates, or even to stay largely equilibrial. Consequently, diversity dynamics remain controversial. The project evaluates the dynamics by combining genetic, geographic, and trait-based analyses across taxa (with focus on tetrapod vertebrates). The results have revealed that diversity dynamics change systematically across regions, taxa, geographic, temporal and phylogenetic scales. For example, regions with low diversity accumulate new species fast, contrary to the common assumption that fast accumulations of species in the tropics generates high tropical diversity. My project instead shows that the new species today accumulate fast at the species-poor high latitudes (Europe, North America). The knowledge of diversity dynamics across regions, taxa and scales will be key to resolve the ongoing controversy. Once we understand these dynamics, we might better identify regions and taxa that deserve heightened conservation efforts. Knowing the underlying principles of diversity dynamics, we can also predict how species diversity will respond to the ongoing global changes.

Цел на проекта

The dynamics of global diversity remain controversial. It has been suggested that the dynamics are expansionary, such that the number of species across regions and continents increases constantly over time. However, some have argued the opposite, namely that species numbers stay largely unchanged most of the time, and the dynamics are therefore equilibrial. This classic controversy has attracted much attention recently because of the new evidence generated by the explosion of molecular data, remote sensing, computing power, and complex statistics. I will use these state-of-the-art resources to formalize and empirically evaluate the theory of scale-dependent diversification. The theory may resolve the controversy, proposing that diversity dynamics and the factors that govern these dynamics vary systematically across spatial, temporal, and phylogenetic scales. To empirically test the theory, I will combine molecular, geographic, climatic, and trait data for birds and mammals, using cutting-edge statistics implemented at supercomputers. The results of the proposed project will not only address the controversy, but also enrich our understanding of global diversity dynamics in general. They will produce numerous implications for evolutionary theory and for the conservation and management of biodiversity.
