Накратко на български

Миграцията на видове между острови, като тези в Канарския архипелаг, се анализира чрез ДНК секвениране и математически модели. Това помага да се разбере как екосистемите реагират на климатичните промени и човешката дейност.

Community Assembly on Islands: A phylogenetic Bayesian approach

BAYESLAND aimed to bring new knowledge about what drives migration of species among islands, in particular in the Canary archipelago. Sequencing the DNA of a group of species allows determining the evolutionary relationships of these species, that is best described by a phylogenetic tree whose branches represent lineages diversifying with time into a variety of species. The phylogeny, coupled with the knowledge of the current geographic distribution of species, allows getting insights into the processes driving species to migrate between islands, across the ocean. Scientists use mathematical models to try and retrace the movements of species in the past (biogeographic models). Biogeographic models estimate the most likely scenarios of past migration, including the number and type of migration events that may have occurred. Such inferences differ a lot among the taxa considered. BAYESLAND aimed to develop some of the currently existing biogeographic models to include new types of data, so as to understand better what determines migration patterns. In particular, the models developed in BAYESLAND should help understand why some species migrate more than others, estimate the importance of migration between populations of the same species, what is the relative importance of geographic versus ecological factors in determining the frequency of migration events. Understanding past migration patterns and processes is important to understand the plasticity of current ecosystems. Within which geographic perimeter do species move so much that they form genetically homogenous populations? How rapidly can species shift their geographic distribution to respond to human disturbance or climate change?

Цел на проекта

Biologists have sought to understand geographic patterns of species distribution for centuries. The process of community assembly, which determines how species integrate and maintain in local assemblages, is key to understanding the factors underlying species distribution. However, the extreme complexity of ecosystems has prevented the development of a general theory of biogeography and community ecology. This is exemplified by the current schism between ecological and historical biogeography. Historically, short-time, ecological explanations such as species interactions with the environment, have dominated the field. Only recently has it been acknowledged that community composition must also be determined by historical factors, and as such the future of community ecology and biogeography must bridge ecological and historical paradigms. To this end, BAYESLAND will analyse biogeographical patterns in islands by combining ecological and historical approaches. This will be done by developing new biogeographic models using Bayesian inference for estimating historical processes of community assembly, while also accounting for (i) ecological differences among lineages, and (ii) the influence of ecological factors on historical processes. This project is expected to result in novel cutting-edge analytical techniques in biogeography. In addition, the application of these new tools to extensive molecular datasets from the Canary Islands is likely to offer new predictions on community assembly. BAYESLAND will transfer to the fellow the host's strong experience in analytical biogeography and macro-ecology, complementing his experience in eco-evolutionary studies of island communities. The fellow will develop skills in method development, NGS, theoretical knowledge and project management, which will be paramount to his career development.
