“…All samples were collected by hand. Allospecies were identified using conchiological features (Garbar 2003;Mezhzherin et al 2005;Garbar & Garbar 2006). Collected animals were subjected to obligatory (Khlebovich 1981) 15-days acclimatization under the following conditions: water volume 30 l, individuals density 4 ind/l, water temperature 20-23° С, pH 7.7-8.6, oxygenation 8.2-8.8 mg (O2) /l.…”

“…It was recently established (Mezhzherin et al 2005;Garbar 2003) and confirmed (Garbar et al 2020;, that the only European and West Siberian (till the Ob river basin) Planorbidae representative -Planorbarius corneus (Linnaeus, 1758) is not a species as having known before, but superspecies complex P. (superspecies) corneus s. l. It consists of two vicaristic allospecies "western" and "eastern", whose ranges are separated by narrow (about 100 km) zone of introgressive hybridization, which Ukraine belongs to. The first one occupies the western and central part of Right-Bank Ukraine, and the second onenorthern and north-eastern territories of Left-Bank Ukraine, and the extreme south of its Steppe zone (from Siverskyi Donets river to Danube river inclusively).…”

Іnfluence of some heavy metals to the pulmonary and direct diffusive respiration of the great ramshorn Planorbarius corneus allospecies (Mollusca: Gastropoda: Planorbidae) from the Ukrainian river system

The vicaristic genetic allospecies (“western” and “eastern”) of superspecies complex Planorbarius corneus s. lato from Ukrainian river network have the combined bimodal respiration mode. These molluscs use their true lungs for atmospheric oxygen breathing, and the diffusive (surface) respiration is used for soluble oxygen consumption. Oxygen transportation to different tissues and organs and carbon dioxide from them to lungs occurs due to respiratory pigment hemoglobin in their liquid internal medium (hemolymph), circulating in vessels, lacunas and sinuses of these animals’ open circulatory system. The aim of present study was to clarify the features and difference levels of lung and surface respiration for “western” and “eastern” allospecies under the impact of heavy metal ions in water environment (MPC: 0.5, 1, 2, 3). It was established that the toxins could be ranged by their toxicity level for activation of molluscs’ respiratory function: Cu2+>Zn2+>Ni2+ >Mn2+. The “eastern” allospecies appeared to be more sensitive and less durable for all aforementioned toxins by both lung and direct diffusive respiration, comparing to the “western” allospecies.

Comparative Karyotype Analysis of Slugs of the Genus Arion (Gastropoda, Pulmonata, Arionidae). Harbar, A. V., Kadlubovska, N. S., Harbar, D. A. -Karyotypes of four species of the genus Arion were investigated, namely, A. distinctus (2n = 48m + 8sm = 56; FN = 112), A. lusitanicus s. l. (2n = 4 4m + 6 sm + 2st = 52; FN = 104), A. fuscus (n = 26, 2n = 52, FN = 104) and A. fasciatus (n = 29, 2n = 58, FN = 116). Th e karyotype of A. lusitanicus s. l. was identical to those of A. fuscus, A. ater and A. rufus. Th e karyotype of A. fasciatus in the haploid number of chromosomes is identical to another close species -A. circumscriptus (n = 29) from the United Kingdom. Th e identical number of chromosomes in species of the subgenus Arion (A. lusitanicus s. l., A. ater, A. rufus) and species of the subgenus Mesarion (A. fuscus) (n = 26) may be a reason for their merging. K e y w o r d s: slugs, Arion, chromosomes, karyotype. Сравнительный анализ кариотипов рода Arion (Gastropoda, Pulmonata, Arionidae). Гарбар А. В., Кадлубовская Н. С., Гарбар Д. А. -Исследованы кариотипы четырех видов слизней рода Arion: А. distinctus (2n = 48m + 8sm = 56; FN = 112), A. lusitanicus s. l. (2n = 44m + 6 sm + 2st = 52; FN = 104), A. fuscus (n = 26, 2n = 52, FN = 104) и A. fasciatus (n = 29, 2n = 58, FN = 116). Кариотип A. lusitanicus s. l. оказался идентичным A. fuscus, A. ater и A. rufus. Кариотип A. fasciatus по гаплоидному числу хромосом идентичен другому близкому виду -А. circumscriptus из Великобритании (n = 29). Идентичные числа хромосом у представителей подродов Arion (A. lusitanicus s. l., A. ater, A. rufus) и Mesarion (A. fuscus) (n = 26) могут быть основанием для их объединения. К л ю ч е в ы е с л о в а: слизни, Arion, хромосомы, кариотип.
