General information

Name of the project: Biology of marine invertebrates

Strategy for Scientific and Technological Development Priority Level: в, г


Goals and objectives

Research directions: Research of biological resources of the World Ocean

Project objective: Complex research of biological diversity and biological resources of invertebrates of Far Eastern seas of Russia at all levels of organization of living matter – from biocenotic to molecular.


The practical value of the study

  • We have proposed a complex study of biological diversity of separate mass groups of phyto- and zoobenthos of open sand coasts and estuary zones of the Sea of Japan to determine trophic connections in floor ecosystems characterizing the role of single trophic and taxonomic groups of hydrobionts in regulation of decomposition of organic substances and energy flow.
  • Our researcher have developed and implemented methods of laboratory diagnostics of the state of populations of commercial invertebrates to determine various pathologies both for implementing express-tests in marine farms and for preservation of the marine biodiversity. We have researched mechanisms of activation of expression of growth factor genes which will help to solve the problem of increase of low proliferation activity of cells in the environment of a culture of cells of marine invertebrates – producers of mineral structures. We have developed and successfully utilized methods of preparation of nematode tissue specimens for immunological analysis.
  • We have assessed efficiency of immunostimulation complexes (tubular immunostimulating complexes based on biologically active substances produced from marine hydrobionts) as adaptive carriers of virus antigens and demonstrated their promising prospects for applications in development of new generation nanovaccines for vaccinations against epidemic diseases. We have also demonstrated high anti-tumor activity of created tubular immunostimulating complexes. We have developed a new technology for cryoconservation of marine hydrobionts at super-low temperatures that allows to significantly increase output of viable cells.

Education and career development:

  • One doctoral dissertation and 15 candidate dissertations have been defended.
  • We have created 10 new educational courses: «Regional ecological problems», «Introduction to neuron biology», «Marine ecology», «Summer field case study in evaluation of quality of natural water», «Flow cytometry as a tool for analysis of cell populations», «Comparative anatomy of invertebrates», «Introduction to marine ecology», «Theory and methodology of scientific research», «Introduction to molecular ecology of microorganisms», «Methods of cytology research».

Organizational and structural changes: The Laboratory is a part of the collective utilization center of the Far Eastern Federal University. A wide range of equipment for conducting research in biology is represented at the Laboratory: genetics, immunology, microscopy, biochemistry devices etc.

Other results: Members of the academic staff of the Laboratory in collaboration with the Far Easter Department of the Russian Academy of Sciences participated in major international experiments: in the Sea of Okhotsk (the Kuril basin) and the Bering Sea (the Piip volcano) (SokhoBio, SoJaBio) within the international scientific program CeDAMar (Census of the Diversity of Abyssal Marine Life); in the Kuril–Kamchatka Trench region of the Northwestern Pacific (KuramBio I and II). During expeditions we have demonstrated efficiency of usage of remote controlled submarines in hydrobiological research and for assessment of state of marine bioresources. As a result, research has demonstrated high biological diversity of deep-sea regions of the Pacific ocean and described a significant number of new species.

Collaborations:

  • Synthetic Epigenetics Lab of the University of Edinburgh (United Kingdom): internships of three Laboratory's young at the University of Edinburgh
  • Senckenberg Research Institute and Natural History Museum (Germany): collaborative publications, joint expeditions (two on board the Russian research vessel «Academician M. A. Lavrentiyev» in the deep-sea basin of the Sea of Japan (SoJaBio–2010) and in the Kuril trench of the Sea of Okhotsk (SokhoBio–2015) and two using the German research vessel «RV Sonne» in the abyssal zone of the Northwestern trench of the Pacific Ocean in the region of Kuril–Kamchatka Trench (KuramBio–2012) and the ultra-abyssal zone of the Kuril–Kamchatka Trench (KuramBio II–2016)
