Spatial and temporal analysis of frequency distribution patterns of the Rana esculenta (= lessonae )- specific allele, Ldh-B 71 , in the populations and individuals of R. ridibunda from the Middle Dnieper region was performed. It was established that the allele was accumulated in the populations of Kiev, where on average 15 to 25% of individuals s...

n the basis of genetically identified series of green frogs complex Rana esculenta main d³agnostic indices of the hind legs were identified. The best diagnostics was achieved in distinguishing R. esculenta L., 1758 (=lessonaeCamerano, 1882) (90% – average percentage of identified specimens), somewhat less – R. ridibunda (87,6%), a less of all – hyb...

The structure of the green frogs hybrid populations Rana esculenta complex from the Middle Dnepr basin located in the gradient from the total urban to wildlife landscapes far from Kyiv was studied by the biochemical genetic marking.

Along with decrease in numbers among amphibians in Eastern Europe nowadays newts especially suffer from invasive predatory fish and turtles. Such aggressive predator as P. glenii has recently occupied water bodies important for newts' breeding. The fish eat eggs, larvae and even adult individuals. Using the ecological niche approach, it was showed...

The spread of phytophagous pests are often associated with global warming. These species may be of interest in terms of biological indication of climate changes. We considered the locust digitate leafminer P. robiniella. In Ukraine it was recorded firstly in 2003. In 2020-2021 we found areas of massive R. pseudoacacia leaf damage caused by the pest...

An increasing number of thermophilic invasive species are spreading and becoming naturalized in Eastern Europe, at least partially due to recent climate change. This can be exemplified by current expansion of the red-eared slider, Trachemys scripta, in Latvia and Ukraine. We collected 44 records of the species in Latvia and 79 in Ukraine. Two of th...

The study of the distribution of protected animal species in Europe is especially relevant in a changing climate. Therefore, in this work, we tried to solve the problem of the possibility of habitation of tortoises Testudo graeca Linnaeus, 1758 and Testudo hermanni Gmelin, 1789 in Eastern Europe by using species distribution models (SDMs). We used...

Abstract. Our study provides a review of colour anomalies in amphibians from Ukraine during the 20th and early 21st centuries. Observations including melanism, flavinism, leucism, and blue axanthism were assembled from the published literature (1909– 2018) and during field surveys (2000–2017). Blue colouration was the most common abnormal variant (...

Helminth infracommunities were studied at 174 sites of Latvia in seven hosts from six amphibian taxa of different taxonomical, ontogenic and ecological groups. They were described using a standard set of parasitological parameters, compared by ecological indices and linear discriminant analysis. Their species associations were identified by Kendall...

Amphibians are the most threatened group of vertebrates. While habitat loss poses the greatest threat to amphibians, a spreading fungal disease caused by Batrachochytrium dendrobatidis (Bd) is seriously affecting an increasing number of species. Although Bd is widely prevalent, there are identifiable heterogeneities in the pathogen’s distribution t...

We examined Emys orbicularis (Linnaeus, 1758) populations from Latvia and Ukraine. Annual means for temperature and precipitation are 5.8°C and 655.6 mm (29 points) and 7.8°C and 595.6 mm (602 points) in Latvia and Ukraine, respectively. Using a separate distribution model for each of two different regions with ecological niche modeling technique (...

The European pond turtle Emys orbicularis is the only autochthonous species of turtles in Latvia and Ukraine. The study of the influence of climatic factors on morphology and ecology is of great interest. Studying the morphology of marginal populations, it was concluded that turtles' hatchlings vary significantly in three parameters. Juvenile turtl...

Creation and expansion of the Emerald Network (EN) objects is one of the most promising directions of the nature conservation development in Ukraine according to European standards. The aim of EN objects designing is to assess the state of conservation of habitats and flora/fauna species’ populations on a pan-European level. It is assumed that the...

Habitat modification affects amphibians indirectly by reducing energy reserves and energy allocated to growth and reproduction, and by affecting population dynamics and viability. Marginal populations of amphibians in Latvia and Ukraine are particularly vulnerable. On the other hand, several studies have shown a positive relationship between human...

The results show that for Ukrainian specimens the independent variance (77%) was totally concentrated in PC1, whereas for the Latvian specimens it was distributed between PC1 (70%) and PC2 (14%). Shifts demonstrated in phenotypic integration are related to environmental changes (Goswami et al., 2015). Our findings support this notion however more r...

Rare and protected species are particularly vulnerable to habitat changes (e.g., mires, virgin forests, wetlands, wet meadows, etc.) dut to climate and themselves may be affected by changes in temperature and/or precipitation. Our study aimed at predicting possible changes affecting habitats of such species, exemplified by amphibians (Epidalea cala...

Current climate changes and growing anthropogenic pressure significantly alters wildlife habitats. This leads to extinctions or accelerated adaptation to changing conditions by which large numbers of abnormal phenotypes may appear in the population. In this respect certain species of amphibians and reptiles surviving under severe anthropogenic cond...

Due to global climate change, new species appear in many regions of the world. An interesting example is the introduced of the sub-Mediterranean common wall lizards of the P. muralis in territories outside the natural distribution area (Kraus, 2009). This species has been introduced in different places of Europe: Germany (Schulte et al., 2011), Cze...

GIS modeling of 138 georeferenced point data of anomalies in amphibians in Ukraine (data from both the literature and personal field surveys) revealed a rather poor, but statistically significant correlation of the numbers of anomalies with the anthropogenic impact measured by the Human Footprint (r=0,268, p=0,0025). We consider that in certain cas...

In this study, we aimed at projecting the availability of suitable habitat for an endangered amphibian species, the Fire-bellied toad, Bombina bombina, under historical climate (summarizing conditions during 1961-1990) and projected data (2050) available from the CliMond database.

In this study we consider the widespread and rapid invasion in Eurasia of Perccottus glenii and its potential impact on native biota, exemplified by presumed negative interactions of this fish with the fire-bellied toad (Bombina bombina), a rare and protected species in Latvia and European Union.

We used GIS modeling (DIVA-GIS, Maxent) to simulate the potential distribution of Zootoca vivipara. For modeling, we used a database including information from our studies and literature, comprising 190 points of lizard samples (including 7 points for melanistic lizards). It can be concluded that the distribution of Z. vivipara in Ukraine depends o...

The study of the environmental factors' effects on the progress of embryonic and post-embryonic ontogenesis is an important trend in modern investigations. Amphibians are often used for this purpose as model objects.

Many lacertid lizards are known for their great intraspecific variation, especially in patterns and coloration. This variation has often led to the description of many subspecies or morphs, which is reflected in inconsistent taxonomy when these subspecies are put into a molecular phylogenetic framework. As a good example we can provide green lizard...

Amphibians are greatly affected by invasive species through direct predation and competition. Being triggered by climate change, the invasion of Perccottus glenii (the Chinese sleeper) in Eurasia may have detrimental consequences for the fire-bellied toad (Bombina bombina). The invader can feed upon B. bombina toads and juveniles and compete for fo...
