“…Вновь образованные популяции тюльки отличаются от материнских популяций и между собой по линейновесовому росту, продолжительности жизни, морфологическим и биохимическим показателям (Sharonov, 1969;Kujbyshevskoe vodohranilishhe, 1983;Shevchenko, 1991;Karabanov, 2009;Kas'janov, 2009;Slyn'ko et al, 2010). Кроме того, на разных фазах натурализации вселенца изменяются его популяционные характеристики, в том числе и динамические, от которых зависит прохождение последующих фаз и дальнейшая роль вида в экосистеме.…”

В двух водохранилищах Днепровского каскада выявлены периоды прохождения фаз натурализации массового вида рыб, что важно для изучения данного процесса у различных видов в разных регионах и для понимания роли чужеродных видов в их рыбном населении. Натурализация тюльки в рядом расположенных водоемах протекала по-разному. В акватории будущего Днепродзержинского водохранилища этот вид проник за два года до строительства плотины, а в Кременчугское он вселился через четыре года после его создания. Детализация начала фаз натурализации основана на анализе динамических фазовых портретов уловов тюльки исследовательским тралом

A comparative analysis of juvenile anadromous and freshwater (stream) forms of the Black Sea brown trout Salmo trutta labrax Pallas, 1814 was conducted using 10 meristic and 62 morphometric characters of cranial bones. This analysis included the counts of teeth and pores in the bones, as well as measuring of their shape characters. As a basis for comparison, data on juvenile anadromous and freshwater Atlantic salmon Salmo salar Linnaeus, 1758 were used. The osteological differences between ecological forms were more pronounced in the brown trout than in the Atlantic salmon. In the brown trout, a greater number of meristic characters differentiated the forms compared to the salmon. However, for morphometric characters, the reverse pattern was observed. The freshwater forms exhibited characteristics intermediate to the anadromous forms of the two species, being more similar to the anadromous form of their species than to each other. Juvenile anadromous Black Sea trout typically had the fewest teeth, while juvenile Atlantic salmon had the most, with freshwater forms showing intermediate values. The most significant differences in the shape of cranial bones were also observed between the juvenile anadromous forms of two species. The characteristics pertaining to the number of pores in cranial bones did not reveal clear patterns when comparing the samples. Among the studied bones and characteristics, those showing the most significant differences between Black Sea trout and Atlantic salmon were identified, and species-specific features were noted. The results obtained show that juveniles of different ecological forms within the same species of the genus Salmo exhibit statistically significant osteological differences, suggesting a high genetic determination of these traits and the influence of selection within river systems on the divergence between freshwater and anadromous forms. Despite this, the variability in all studied characteristics indicates plasticity, resulting in the differences between the species and ecological forms within the genus Salmo typically not reaching the threshold for subspecies differentiation. These results align with previous studies on adult individuals and indicate that the freshwater form of the Atlantic salmon displays osteological characteristic of a more ancestral species, namely the brown trout.
