ИСТИНА

Предлагаемый проект направлен на изучение филогении и сравнительной филогеографии брюхоногих моллюсков бореальных и арктических вод. Основной целью проекта является реконструкция истории формирования современного разнообразия фауны брюхоногих моллюсков Арктики на примере двух крупных филогенетически близких групп – Nudibranchia и Cephalaspidea. Проект охватывает широкий спектр таксонов, представленных в фауне северных морей, и направлен на изучение всей акватории бореальных и Арктических морей России. При выполнении работ будет использован интегративный подход, объединяющий классические морфолого-анатомические исследования и современные методы микроскопии, а также актуальные молекулярно-филогенетические методы с новейшими подходами к биоинформационному анализу генетических данных.

Phylogeography is now an actively developing field of biological knowledge. It includes a wide range of tasks aimed at studying the processes of microevolution, historical demography, animal behavior, their distribution, evolutionary history of various taxa and the influence of various factors, abiotic and biotic, on the formation of modern biological diversity. Although for terrestrial animals and plants, studies of the phylogeographic structure have become almost “classic”, in the case of marine organisms, including invertebrate animals, their number is small. Most of the work is related to studies of the population structure of common species, which allows covering only a very short geological period. The proposed project is aimed at studying the phylogeny and comparative phylogeography of gastropod mollusks in boreal and arctic waters. The main goal of the project is to reconstruct the history of the formation of the modern diversity of the fauna of gastropods in the Arctic using two large phylogenetically related groups as examples - Nudibranchia and Cephalaspidea. The project covers a wide range of taxa represented in the fauna of the northern seas, and aims to study the entire water area of ​​the boreal and Arctic seas of Russia. During the work, a comprehensive integrative approach will be used, combining classical morphological and anatomical studies and modern microscopy methods, as well as current molecular phylogenetic methods with the latest approaches to bioinformation analysis of genetic data. The generalized results of the project will expand our ideas about the biological diversity of the Arctic region, allow us to compare the population structures of individual widespread species, analyze the ways of settling the Arctic region, critically review the existing methodological approaches to dating the divergence of studied taxa.
