Герпетологические исследования в Средней Азии и Казахстане: краткая история изучения рептилий, основные достижения и перспективы в XXI веке

Abstract

This review is devoted to the history and progress in herpetological research in Central Asia and Kazakhstan, a region that is positioned within Central Asia. Studies of the herpetological diversity of Central Asia have a long history and are a special field of research. Research in this area has passed through several developmental stages, the first of which was associated with early expeditions which penetrated into Asia including those of P.S. Pallas and I.I. Lepekhin. The interest of naturalists was focused on this vast unexplored territory. The list of prominent researchers-encyclopedists and great travelers to work in Central Asia included E.I. Eichwald, A.A. Kaiserling, V.A. Perovsky, A.I. Schrenk, G.S. Karelin, G.I. Radde, G.I. Sievers, E. A. Eversmann, O. A. Grim, A.I. Lehman, O. Bettger, V.D. Alenitsyn, N.A. Severtsov, M.N. Bogdanov, A.P. Fedchenko, S.N. Alferaki, P. Y. Schmidt, N.A. Zarudny, L.S. Berg, and many others. At this historical stage, herpetological studies were often not separated into a special scientific branch and were carried out as part of complex zoological works. Later, in the twentieth century, large-scale herpetological studies were launched; a preliminary inventory of the fauna was carried out, many species were described, a synopsis of the species composition was created, and a zoogeographic analysis of the arid territories of Central Asia was performed. For the first time, the outstanding herpetologist A.M. Nikolsky, whose name our Herpetological Society bears, undertook this task. The history of research in the twentieth century and the current trends of the herpetological branch of zoology, which require an analytical understanding of descriptive and comparative data accumulated over previous periods, are considered in detail in this article. The use of an integrative approach in zoological research is becoming increasingly relevant, including the results of studying diversity structures, modes of speciation, and ecogeographic trends in a phylogenetic context. An integrative approach with the use of molecular genetic methods has allowed us to approach the solution of issues that have confounded many generations of herpetologists. The horizons of comparative analyses have also been expanded due to the increased availability of new, previously unexplored territories for researchers. Data obtained are of practical importance in the preparation of proposals for the allocation of protected areas and the assessment of the conservation status of particular species of model groups, including reptiles. Examples of integrative studies in model groups of reptiles (in various groups of turtles and lizards) are therefore also presented in this article.
