Igor Zagorodniuk

I. Zagorodniuk started his zoological research in ornithology when he was a student of Taras Shevchenko National University of Kyiv. His diploma project at University (and also the intermediate works) was devoted to the study of migrations and flying of birds.Tsvelykh A. N., Mikhalevich О. А., Zagorodnjuk I. V. The relationship between the frequency of wings flapping and the flight speed of the gray heron (Ardea cinerea L.) // 18th International Ornithological Congress — M., 1982. — P. 139–140.Tsvelykh A. N., Zagorodnjuk I. V., Mikhalevich О. А. [http://terioshkola.org.ua/library/zag/zag-1984-ardea-flight.pdf The speed of flight and frequency of wing strokes in Ardea cenerea] // Zoological journal. — 1984. — Vol. 63, № 4. — P. 590–597.

Also, being a University student, I. Zagorodniuk started the study of amphibians (their hybrid zones in particular), conducted the experiments on biotope association of the amphibian group Bombina bombina – Bombina variegata, and also conducted experiments on the energy of Bombina species in winter time and the influence of wintering on the age structure of this species populations.Zagorodniuk I.V. The influence of wintering on the age structure of the populations of Bombina bombina // A species and it's its productivity in the range. — Sverdlovsk, 1984. — Part 5. — P. 18–19.

At the same time, I. Zagorodniuk started the study of karyotypes of amphibians and rodents. When he began his work at I. I. Schmalhausen Institute of Zoology, the subject of his research was shifted towards the study of rodents. The first publication on this subject was devoted to the karyotypic variability of Microtus arvalis.[http://terioshkola.org.ua/library/zag/zag-1985-microtus-karyotype.pdf Zagorodnyuk I. V. About karyotype variability of common voles // Vestn. zool. — 1985. — № 6. — P. 79–82.]

The results of this research became the basis of justification of the species independence for Microtus arvalis — M. obscurus. This became one of the results of PhD research by I. Zagorodniuk and the subject of the most cited publication by the scientist.[http://terioshkola.org.ua/library/zag/zag-1991-(obscurus).pdf Zagorodnyuk I. V. Karyotypic Variation of 46-chromosome Forms of the Vole Group of Microtus arvalis (Rodentia): a taxonomic evaluation // Vestn. zool., 1991, Vol. 25 (1): 36–45 + 3rd page of cover] (in Russian, with English summary)

Taxonomic investigations make up a significant part of the scientific work of I. Zagorodniuk. This investigations were shifted from a description of small taxa to the group analysis and the discovery of patterns of formation and existence of low and high levels of taxonomic diversity.

In this investigation, considerable attention is given to the groups of evolutionary and morphologically close species, primarily rodents. As a result of this cycle of research, 8 new taxa were described and a significant number of taxonomic permutations were proposed.

The following taxa are described as new to science:

• Volemys Zagorodnyuk, 1990[https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=632606 ITIS Standard Report Page: Volemys]
• Apodemini Zagorodnjuk, 2001[http://terioshkola.org.ua/library/zag/zag-2001-(keymurid).pdf Zagorodniuk I. V. Levels of taxonomic and morphological differentiation in European groups of rodents from the family Muridae (Mammalia)] // Reports Natl. Acad. Sci. Ukr., 2001, N 5: 151–157] (In Ukrainian, with summary in English)
• Sorex minutus dahli[http://terioshkola.org.ua/library/zag/zag-2001-(mamtype-NNPM).pdf Pysanets E. (ed.). Dotsenko I. B., Zagorodniuk I. V., Manilo L. G. et al. A Catalogue of the type-specimens in the zoological museum, National Museum Natural History, Ukrainian Academy of Sciences. — Kyiv: Zool. Museum of NNHM NASU, 2001. — 138 pp. (In Ukrainian, with summary in English)]. Chapter about mammals is available: Zagorodniuk I., Shevchenko L. S. Mammals // Pysanets E. M. (ed.). A Catalogue of type specimens in zoological museum, National Museum of Natural History, Ukrainian Academy of Sciences. — Kyiv, 2001. — Pp. 105–121. (In Ukrainian)
• Apodemus (Sylvaemus) falzfeini (later the geographical boundaries have been substantially expanded, which eventually led to a change in the scientific name, and the described form is now a subspecies Sylvaemus witherbyi falzfeini)
• Microtus rossiaemeridionalis ponticus
• Sylvaemus sylvaticus sabinae
• Terricola tatricus zykovi
• Arvicola scherman gutsulius[http://www.departments.bucknell.edu/biology/resources/msw3/browse.asp?id=13000178 Mammal Species of the World — Browse: scherman]
• Eptesicus lobatus[http://terioshkola.org.ua/library/zag/zag-2009-eptesicus.pdf Zagorodniuk I. Morphology of post-calcarial lobe in bats and its variation in Eptesicus “serotinus” (Mammalia). Visnyk of Lviv Univ. Biology series. 2009. Is. 51. p. 157–175.] — (In Ukrainian, with summary in English)

Besides the taxa described for the first time, the researcher also substantiated the species, subfamily or generic statuses of a number of other taxa, which names were known as synonyms of other species or genera for a long period of time.

• Sylvaemus uralensis (Pallas, 1811)  — is currently recognized as a separate species that includes Apodemus microps (its dіstribution was recognized only in Central Europe, now - on Ural and Altai).
• Mus spicilegus Petenyi, 1882  — is currently recognized as a separate species that was a part of Mus musculus.
• Microtus obscurus (Eversmann, 1845)  — is currently recognized as a separate species or a group of subspecies of the species Microtus arvalis.
• Arvicola scherman (Shaw, 1801)  — is currently recognized as a separate species or group of subspecies of the species Arvicola amphibius (the last name was also returned in use on the basis of the review of the superspecies «Arvicola terrestris»).
• Sicista loriger (Nathusius, 1840)  — is currently recognized as a separate species or group of the subspecies of the species Sicista subtilis.
• Sylvaemus Ognev, 1924  — is currently recognized as a separate genus or subgenus of the genus Apodemus.
• Terricola Fatio, 1867, — is currently recognized as a separate genus or subgenus of the genus Microtus.
• Alexandromys Ognev, 1914, — is currently recognized as a separate genus or subgenus of the genus Microtus.

In the publications by I. Zagorodniuk a number of specifications are proposed regarding the interpretation of ranks and scopes of superfamily groups of mammals and unified names of some other taxa.[http://terioshkola.org.ua/library/zag/zag-2008-(ordomam).pdf Zagorodniuk І. Scientific names of mammalian orders: from descriptive to uniform // Visnyk of Lviv Univ. Biology series. — 2008. — Is. 48. — P. 33–43.]

• Leporiformes (for Lagomorpha)
• Muriformes (for Rodentia)
• Soriciformes (for Insectivora)
• Lemuriformes (for Primates)
• Vespertilioniformes (for Chiroptera)
• Caniformes (for Carnivora)
• Equiformes (for Perissodactyla)
• Balaeniformes (for Cetacea)
• Cerviformes (for Artiodactyla)

I. V. Zagorodniuk is the initiator of the establishment and the founder of Theriological school — annual gathering of theriologists taking place in different regions of Ukraine since 1993.{{Cite web|url=http://terioshkola.org.ua/en/main.htm|title = Main idea of the Theriological School}}

Scientific interests: fauna and ecology of terrestrial vertebrates of Eastern Europe, biogeography and evolution of cryptic species, species concept and models of speciation, rare species and adventitious biota.
