В работе приводятся результаты эксперимента по выращиванию молоди батурской жабы на различных кормах. Обсуждается эффективность использования мраморного и туркестанского тараканов в кормлении батурской жабы в лабораторных условиях.
The work presents the results of an experiment on growing juvenile Batura toad on various feeds. The paper discusses the effectiveness of using marble and Turkestan cockroaches in feeding the Batura toad in laboratory.
The paper presents the results of age and growth studying of the Tajikistan toadhead agama Phrynocephalus sogdianus by skeletochronology. A total of 29 adult individuals (14 females and 15 males) from the vicinity of Uchkyzil (Termez district, Surkhandarya region, Uzbekistan) were studied. All animals, on the section of tubular bones had a birth (hatching) line appearing shortly after the lizards hatching. The majority of the sample consisted of one-year-old and two-year-old specimens (89.7%). The age of females and males varied between 1–3 years, averaging 1.53 and 1.71 years, respectively. The expected calculated life expectancy for females after one wintering was 2.25 years, for males 2.06 years. Females and males did not differ in body length. The length of the males’ body depended on their age. Males aged one and two years statistically significantly differed in size among themselves. The authors note that P. sogdianus has very high growth rates (growth coefficient k is 2.84 in females and 1.40 in males), exceeding that of other toadhead agamas.
The paper discusses the distribution of Bufo verrucosissimus in the North Caucasus. It is noted that the absolute majority of findings of this species in Russia have occurred in the Black Sea basin. All currently known habitats of B. verrucosissimus in the Caspian basin are located in the upper part of the Kuma River basin (the vicinity of Kislovodsk town and Borgustanskaya village in the Stavropol region). New points of findings are shown between the mouths of the Ugol’naya and Kladbishchenskaya Balka rivers (left tributaries of the Kuma River), as well as near Bekeshevskoye Lake (Predgorniy district, Stavropol region). The authors believe that B. verrucosissimus may be distributed along the gallery forests of the Kuma River up to Georgievsk town and Soldato-Alexandrovskoye village.
The paper presents the results of using multiplicative indices for species identification of polyploid green toads of Central Asia. Live adult individuals of Bufotes baturae (24 females and 17 males) from the territory of Tajikistan and B. pewzowi (14 females and 24 males) from Kazakhstan, Uzbekistan and Tajikistan were studied. The animals were caught in nature, measured and immediately released. The species belonging of the studied green toads was established by cytogenetic methods. According to the results of discriminant analysis, six proportionality indices were significant for the species identification of females. The females of B. batura and B. pewzowi formed separate non-overlapping clusters in the discriminant function space, and the level of their reliable classification was 100%. For the identification of B. batura and B. pewzowi males, four significant body proportionality indices were identified using discriminant analysis. The clusters of these two species in the space of discriminant function touched, and the level of correct classification was 97.6%. As a result of our research, one multiplicative index common to males and females was identified for highly reliable identification of B. baturae and B. pewzowi, as well as one multiplicative index separately for males and females of the studied species. The authors conclude that multiplicative indices based on standard morphometric indicators can be used for the practical determination of polyploid green toads.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
