This book features a selection of works presented in the 3rd International Conference on BioGeoSciences in a unified framework. It focuses on the physical and mathematical modelling of natural processes and environments at different spatial and temporal scales. This interdisciplinary book presents a comprehensive collection of case studies grouped according to the planetary ''spheres'': lithosphere, hydrosphere, atmosphere, magnetosphere and biosphere. It serves as a valuable resource for scientists engaged in natural and exact sciences.

Prof. Dr. Rolando Cardenas received his Ph.D. in Theoretical Physics and a second-degree Doctorate focused in Astrobiology and Earth Sciences. He conducts the interdisciplinary Planetary Science Laboratory at Universidad Central 'Marta Abreu' de Las Villas since its foundation in 2011. In the decade of 2000's, he was recipient of annual awards of the Cuban Academy of Sciences in three occasions for research in Theoretical Cosmology, and in 2016, he was the main contributor for such an award for works on Astrobiology and Earth Sciences. In 2013, the Cuban Council of State awarded him with Carlos J. Finlay Order, the highest in the country for research activity. In 2016 and 2020, he also received the Honorary Distinctions of the Minister of Higher Education for Scientific Research. His research work is in the broad area of mathematical modeling of natural environments at different spatial and temporal scales.

Prof. Dr. Vladimir Mochalov currently works at Petrozavodsk State University, Petrozavodsk, Russia. He received the Ph.D. degree in electronic engineering from Moscow Technical University of Communications and Informatics. His research interests include networks structure synthesis, artificial intelligence, bio-inspired algorithms, query-answering systems and Big Data, and their applications to Natural and Exact Sciences.

Prof. Dr. Oscar Parra is a biologist and professor at the Natural Resources and Oceanographic Sciences Faculty and founder Director of the Environmental Sciences Centre of the University of Concepción (Concepción, Chile). He is a very experienced researcher in the use of standard physical, chemical, and biological methods of water ecosystems, specialized on taxonomy and ecology of freshwater phytoplankton and phytobenthos. His research cover interdisciplinary studies of freshwater systems (lakes and rivers) on a watershed scale. He is the author of about 200 hundred scientific papers, book chapters, and books, and he has edited a number of books dealing with aquatic biota and management of water resources in Chile. He has participated as a leader of several national and international collaborative scientific projects and as a consultant of national and international institutions and organizations, e.g., UNESCO (Albania, Libia, Costa Rica, Brazil, Uruguay, and Argentina). Funding agencies for his research include PNUD UNESCO, European Commission, Italian Government, Germany Government, and Chilean National Science Commission.

Prof. Dr. Osmel Martin received his Ph.D. in Theoretical Physics and conducts research at the Planetary Science Laboratory at Universidad Central 'Marta Abreu' de Las Villas since its foundation in 2011. In 2016, he was one of the main contributors for an award of Cuban Academy of Sciences for works on Astrobiology and Earth Sciences. His current research work is in the broad area of mathematical modeling of natural environments, at different spatial-temporal scales, with emphasis in Atmospheric Sciences, BioGeoSciences, and Astrobiology.
