Background. Two species of water frogs, Pelophylax ridibundus and Pelophylax lessonae, and their hybrid, Pelophylax kl. esculentus, are widespread in Ukraine. The objective of this study was to investigate the population structure of various types of hemiclonal population systems (HPS) of water frogs, formed due to the coexistence of frogs in the s...

Introduction: In this article, we present a literature review of modern, most common, and useful methods of amphibian tracking. Amphibians are the most sensitive group of animals and near 41 % of species are under the risk of extinction. Therefore, the research of spatial movements of amphibians is one of the most topical tasks of modern herpeto­lo...

69 road sections with amphibian mortality known from 2006 in Lviv Region (Western Ukraine) were repeatedly surveyed in 2017. 2078 dead individuals of nine amphibian species were detected and identified on the road surface ( Triturus cristatus , Bombina bombina , Pelobates fuscus , Bufo bufo , Hyla orientalis , Rana temporaria , Rana arvalis , Pelop...

Automobile roads are one of the widespread artificial barriers in the environment. They fragment it and isolate some sites. This leads to significant road mortality of amphibians during their migrations and causes the decrease of amphibian population number. The main goal of this work was to evaluate modern level and character of Lviv province road...

The results of the analysis of the genetic structure in population systems of green frogs on the territory of Lviv and Volyn regions are presented. The material was collected in 2011–2012 in water bodies representing three nature regions of Ukraine – Forecarpathians, Roztochia, and Western Polissia. Three taxonomic groups of green frogs were in a f...

The results of phenotypic variability of water frogs (Pelophylax) analysis depending on internal and external influence factors are presented. 345 individuals of three species (Marsh Frog, Pool Frog and Edible Frog) were taken for the analysis from water bodies of different level of anthropogenic influence. The hydrochemical composition of water fr...

Material for the analysis was sampled in five water bodies of Lviv province in 2011-2016. The water bodies differed from each other by their practical use: "Nyzhankovychi" and "Zhovtantsi" are the water bodies of general use, "Perekalky" is the derivation canal of Dobrotvir thermoelectric power station, "Velykyi Lubin" is a fish pond, and "Cholgyni...

Представлено дані щодо фенотипного розподілу зелених жаб водойм Львівської області різного господарського призначення: рибничі стави, водойми на місці колишніх сірчаних кар'єрів, канал скидних вод Добротвірської ТЕС та дрібні ставки. Виявлено 4 типи популяційних систем. Для фенотипних ознак характерними були: присутність дорзомедіальної смуги і жов...

Проблема видового визначення зелених жаб пов’язана з гібридним способом відтворення особин Pelophylax esculentus. Гібрид успадковує гени обох батьків: жаби озерної Pelophylax ridibundus і жаби ставкової Pelophylax lessonae. Було встановлено, що чотири з досліджених особин є типовим прикладом геміклонального успадкування, а їхня локалізація не зумов...

Зелені жаби України представлені трьома видами, а саме жабою озерною-Pelophylax ridibundus [Pallas, 1771], ставковою-Pelophylax lessonae [Camerano, 1882 «1881»] та їхнім гібридом-їстівною-Pelophylax esculentus [Linnaeus, 1758]. Морфологічно ці види подібні, проте використання індексу F/T дає можливість у польових умовах на 70 % установити їхню видо...
