Abstract A part of the COI mitochondrial barcoding gene was sequenced from seven species of different taxonomical groups: Ambystoma mexicanum (Amphibia, Ambystomatidae), Darevskia lindholmi, Lacerta agilis exigua (Reptilia, Lacertidae), Erinaceus roumanicus (Mammalia, Erinaceidae), Macrobiotus sp. 1 and 2 (Eutardigrada, Macrobiotidae) and Cameraria ohridella (Insecta, Gracillariidae). The sequences were compared with available sequences from databases and positioned on phylogenetic trees when the taxa had not yet been sequenced. The presence of Mexican axolotls in herpetoculture in Ukraine was confirmed. The partial COI genes of the Crimean rock lizard and an eastern sub-species of the sand lizard were sequenced. We demonstrated the presence of two tardigrade mitochondrial lineages of the Macrobiotus hufelandi group in the same sample from the Zeya Natural Reserve in the Far East: one was nearly identical to the Italian M. macrocalix, and the other one is similar to M. persimilis and M. vladimiri. We also confirmed the presence of the invasive haplotype “A” of the horse chestnut leaf miner in Ukraine, in line with the hypothesized route of invasion from Central Europe.

The paper presents data on the ecology of two common species of reptiles in the Tambov Region: the sand lizard, Lacerta agilis Linnaeus, 1758, and the common grass snake, Natrix natrix (Linnaeus, 1758). The material was collected in the Michurinsky, Pervomaysky, Tambovsky and Inzhavinsky (on the territory of the Voroninsky State Nature Reserve) Districts of the Tambov Region during the 2019 field season. Field observations and accounting for the numbers of animals on the routes were carried out in the most typical biotopes for the study sites: in pine forest, deciduous forest, in steppe areas affected to varying degrees by anthropogenic transformation, in floodplains of rivers and along the shores of lakes and artificial reservoirs. Information on the following aspects of the ecology of these reptile species in the region is presented and discussed: habitat distribution and numbers, seasonal and diurnal activity, phenology of reproduction and development and the influence of anthropogenic factors. All materials obtained as a result of our own research are compared with the data of the literature sources cited in the paper. On the basis of wide distribution in the region, relatively high numbers and trends to synanthropy it is stated that the state of the populations of the sand lizard and common grass snake in the region in the present conditions is safe and special measures for their protection are not required.

Lacerta Agilis

Studies of reptile (nonavian reptiles) chromosomes began well over a century ago (1897) with the initial report on the description of sand lizard (Lacerta agilis) chromosomes. Since then, chromosome analysis in reptiles has contributed significantly to understanding chromosome evolution in vertebrates. Reptile karyotypes are also unique, as being the only vertebrate group where the majority of the species possess variable numbers of macro- and microchromosomes, which was first reported for iguanids and teiids in 1921. In addition, many reptiles have microchromosomes as sex chromosomes, highlighting their evolutionary significance, yet very little is known about their evolutionary origin and significance in shaping amniote genomes. Advances in genomic technologies in recent years have accelerated our capacity to understand how sequences are arranged within a genome. However, genomic and cytogenetic analyses have been combined for only 3 species to provide a deeper understanding of reptile chromosome evolution and sequence organization. In this review, we highlight how a combined approach of cytogenetic analysis and sequence analysis in reptiles can help us answer fundamental questions of chromosome evolution in reptiles, including evolution of microchromosomes and sex chromosomes.
