We present nine observations of abnormal amplexus in anurans, reported for the first time from Latvia. In total, nine types of abnormal amplexi are documented for four anuran species: Bombina bombina (Bombinatoridae), Bufo bufo (Bufonidae), Pelophylax lessonae and Rana temporaria (Ranidae). According to the one of our observations, abnormal amplexu...

The spread and outbreaks of phytophagous pests are often associated with global warming. In addition to economic interest, these species may be of interest in terms of biological indication of climate changes. In this context, we considered the locust digitate leafminer Parectopa robiniella Clemens, 1863 (Lepidoptera: Gracillariidae). This phytopha...

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...

We used quantitative PCR to detect Batrachochytrium dendrobatidis (Bd) and Batrachochytrium salamandrivorans (Bsal) in 135 samples of Pelophylax esculentus complex water frogs from 41 Latvian populations. We detected Bd in 18 populations of water frogs. None of the samples was positive for Bsal.

The bloodfeeding leech genus Placobdella is dominated by North American diversity, with only a single nominal species known from Central America and one from the Palearctic region. This is likely due to considerable underestimation of Palearctic biodiversity, but investigations into potential hidden diversity are lacking. To shed light on this, the...
Article
Full-text available
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...
Article
The slow-worm lizards (Anguis) comprise five species occurring throughout most of the Western Palearctic. Although these species are relatively uniform morphologically – with the exception of A. cephallonica, which exhibits a quite unique morphology – they are genetically deeply divergent. Here, we provide detailed distribution maps for each species...

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 (...

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...

Audial surveys of anuran amphibians (frogs, toads and similar) are cost-effective and allow for the coverage of large areas, but they are usually regarded as unsuitable for population size estimations due to imperfect detection. Our study demonstrated a method for obtaining minimum adult population size estimates from vocalising anuran counts by us...

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...
