Introduction
My research interests include ecology, evolution and diversity of crustaceans and other invertebrates, particularly water fleas of the genus Daphnia, freshwater crayfish and gammarid am phipods. Furthermore, I am interested in biological invasions in freshwaters, with one of the key study systems being the pathogen of crayfish plague and its hosts.

Article
Full-text available
Aim: Were postglacial recolonizations facilitated by persistence close to the colonized areas rather than by dispersal ability allowing for colonization from distant sources? This question is particularly relevant for organisms with low active dispersal abilities and lacking specialized propagules. Here we identified glacial refugia of four Central...
Article
Recent discoveries of vast cryptic diversity among various aquatic invertebrates pose a challenge for understanding their ecology and biodiversity patterns, as well as for conservation. We studied the distribution, potential hybridization and habitat preferences of divergent lineages of the hyperdiverse Gammarus fossarum species complex (Crustacea:...
Preprint
Full-text available
Climate change-related heatwaves are major recent threats to biodiversity and ecosystem functioning. However, our current understanding of the mechanisms governing community resilience (resistance and recovery) to extreme temperature events is still rudimentary. The spatial insurance hypothesis postulates that diverse regional species pools can buf...
Article
Full-text available
The widespread presence of North American alien crayfish in Europe is a major driver of native crayfish population declines, mainly because they are chronic carriers of the oomycete Aphanomyces astaci responsible for crayfish plague. Screening for the crayfish plague pathogen in host populations has become a common practice across Europe, but sampl...
Article
Decades of research on geographic variation of birdsong have provided evidence that passerine vocalization often diverges among populations. We asked whether even songs so simple that they superficially resemble stridulating insects vary geographically. We focused on two closely related species of the genus Locustella, the River Warbler (L. fluviat...
Article
Full-text available
Sequences of mitochondrial genes revolutionized the understanding of animal diversity and continue to be an important tool in biodiversity research. In the tribe Helicini, a prominent group of the western Palaearctic land snail fauna, mitochondrial data accumulating since the 2000s helped to newly delimit genera, inform species-level taxonomy and r...
Article
Ringing is one of the most commonly used techniques to monitor bird individuals and collect data on various aspects of their life history. However, this method involves practices (capturing and handling) that might affect individuals' behaviour. Wild animals can remember and learn from previous experiences, and, thus, they anticipate risks and modi...

Full-text available
The article ‘No evidence for hybridization between Calanus finmarchicus and C. glacialis in a subarctic area of sympatry’ (Choquet et al. 2020) concludes that “no evidence supports a potential for hybridization between C. finmarchicus and C. glacialis”. We argue that the InDel markers used by Choquet et al. (2020) may have limited capacity to detec...
Article
Full-text available
The oomycete Aphanomyces astaci is the etiologic agent of crayfish plague, a disease that has seriously impacted the populations of European native crayfish species. The introduction of non-indigenous crayfish of North American origin and their wide distribution across Europe have largely contributed to spread of crayfish plague in areas populated...
Article
Among the broad diversity of songbird vocalisations, song can serve a wide range of different functions depending on the species and context. In many species, aggressive motivation has often been linked with the use of fast repeated series of elements typically referred to as trills. However, only a few studies explored the role of this specific co...
Article
Ringing is the most common technique used for individual marking of passerine birds, informing understanding of many aspects of their behaviour and ecology. Birds caught for ringing may also be substantially handled before release (e.g. to obtain biometric data, blood or feather samples), and all such procedures may affect the subsequent behaviour...
Article
Full-text available
Bioindication has become an indispensable part of water quality monitoring in most countries of the world, with the presence and abundance of bioindicator taxa, mostly multicellular eukaryotes, used for biotic indices. In contrast, microbes (bacteria, archaea and protists) are seldom used as bioindicators in routine assessments, although they have...
Article
Full-text available
The Mediterranean basin is a major centre for land-snail diversity, with many localized endemics, but there are also species widely spread by humans. Both endemics and introductions can be found in the snail genus Helix, which comprises many large-bodied species used for human consumption in the past and present. The Mediterranean clade of Helix is...

Article
Full-text available
Aphanomyces astaci is the causative agent of crayfish plague, a disease responsible for numerous mass mortalities of native crayfish across Europe. In this study, we aim to extend knowledge about the A. astaci distribution in Eastern Europe, with specific focus on the River Dnieper (Ukraine), and summarize presently available information about the...
Article
The crayfish plague pathogen Aphanomyces astaci, which is among the most studied pathogens of aquatic invertebrates, co-evolved with North American crayfish species but threatens crayfish on other continents. The pathogen causes mass mortalities, particularly in Europe. In this study we document 12 crayfish plague outbreaks that occurred from 2014...
Article
Full-text available
Gammarus roeselii is a common European amphipod, characterized by dorsal spines that defend against fish predation. Despite significant variability in spine length and number, the extent of this variation has never been quantified. Furthermore, widespread freshwater Gammarus taxa, including G. roeselii, are diverse species complexes, comprising num...
Article
Exact locations of glacial refugia are relevant for the study of contemporary biodiversity, not only as places less disturbed during the climatic changes but also as sources of rapid expansion of the biota after the Last Glacial cycle. If continuously inhabited over several of the Quaternary glacial cycles, the refugia are readily identifiable by t...
Article
The crayfish plague pathogen (Aphanomyces astaci) can be transmitted through the digestive system of fish, but its dispersal through mammalian and bird digestive tracts has been considered unlikely, and direct experimental evidence remains scarce. We present a small‐scale transmission experiment with European otter and American mink fed with infect...
Article
The spatial distribution of suitable habitats and dispersal abilities of the constituent taxa jointly affect the structure of metacommunities in standing freshwaters. Most studies exploring spatial effects on aquatic metacommunities, however, focus on at most a few taxonomic groups. Within two consecutive seasons, we studied spatial patterns in the...
Article
Full-text available
The causative agent of crayfish plague, Aphanomyces astaci Schikora, was long considered to be a specialist pathogen whose host range is limited to freshwater crayfish. Recent studies, however, provided evidence that this parasite does not only grow within the tissues of freshwater-inhabiting crabs but can also be successfully transmitted by them t...

Article
The genus Aphanomyces (Oomycetes) comprises approximately 50 known species of water molds in three lineages. One of the most notorious is Aphanomyces astaci, the causative agent of crayfish plague. In this study, fresh isolates of Aphanomyces were collected from 20 live specimens of the signal crayfish Pacifastacus leniusculus (Dana, 1852) from Lak...
Article
Full-text available
The multidisciplinarity of integrative taxonomy is particularly useful for clarifying the systematics of speciose groups that are poorly differentiated morphologically, and this approach can also illuminate their evolutionary history and biogeography. Here, we utilize it to examine the systematics and taxonomy of a newly recognized amphipod species...
Article
Song dialects, as a special case of geographic variation in vocalization, are useful tools in the study of a number of topics ranging from cultural evolution to the emergence of reproductive barriers, and thus continue to be the focus of many bird‐song studies. The Yellowhammer Emberiza citrinella is a common Palaearctic bird with a long breeding s...

Full-text available
A complete mitochondrial genome of the Roman snail Helixpomatia Linnaeus, 1758 has been sequenced. The length and gene order correspond to that of other available helicid mitogenomes. We used the mitogenome sequence to reappraise the relationships among the four presumed principal groups of the helicid subfamily Helicinae. The results support the i...
Article
Microsporidia are among the most common microparasites of cladocerans and have potentially significant impact on host populations. However, many of these pathogens are known only from molecular-based studies. We provide ultrastructural data supported by molecular phylogeny for a common microsporidium infecting the Daphnia longispina complex, import...
Conference Paper
Full-text available
Background: The factual diversity of European freshwater crustaceans is scarcely known. This is particularly surprising taking into account their wide applicability in biomonitoring as well as in eco-toxicological and phylogeographical studies. Crustacea, particularly Malacostraca, play a fundamental role in functioning of freshwater ecosystems, be...
Article
Full-text available
Moina micrura Kurz, 1875 (Anomopoda: Moinidae) belongs among the most poorly defined cladoceran species in the world. This species has been considered cosmopolitan and is widely used for laboratory experiments, ecotoxicology, physiology or as live food. Nevertheless, recent molecular analyses corroborated the idea that it is a diverse complex of cl...
Article
Full-text available
Background: The zooplanktonic cladocerans Daphnia, present in a wide range of water bodies, are an important component of freshwater ecosystems. In contrast to their high dispersal capacity through diapausing eggs carried by waterfowl, Daphnia often exhibit strong population genetic differentiation. Here, to test for common patterns in the populat...

1. Numerous freshwater crayfish species are known to become successful invaders when introduced to new territories. One of the most invasive species in this group is the red swamp crayfish, Procambarus clarkii (Girard, 1852). In addition to other characteristics facilitating its invasiveness, it is also a vector of crayfish plague, a disease mostly...
Article
Microsporidia (Opisthosporidia, Microsporidia) are frequent parasites of planktonic cladocerans, including Daphnia (Crustacea, Branchiopoda). Analysis of available molecular data (ITS region and partial ssu and lsu rDNA) of these parasites indicates that many microsporidia infecting daphnids have a common ancestor and represent a large clade, which...
Article
The oomycete Aphanomyces astaci is the causative agent of crayfish plague in populations of native European freshwater crayfish. Molecular analyses showed that several distinct genotype groups of this pathogen, apparently associated with different original host taxa, are present in Europe. Tracking their distribution may thus contribute to understa...
Article
Recent studies of the distribution and diversity of freshwater zooplankton have indicated that the previously understudied Eastern Palearctic is an important biogeographic hotspot. Here, we explored the lineage diversity and reproductive modes of the Daphnia pulex species group across China. Members of this group are often keystone species of stand...
Article
Full-text available
Helix lucorum is a large synanthropic land snail of substantial economic importance, which has been recently reported from a number of new sites in Western, Central, and Eastern Europe. It is an originally Anatolian and Caucasian species, but its presumed natural distribution also covers the south and east of the Balkans. Populations of unclear ori...

Knowledge of the mechanisms facilitating the coexistence of closely related competing species is crucial for understanding biodiversity patterns. The concept of convergent agonistic character displacement (ACD) suggests that interspecific interference competition may lead to convergence in territorial signals between species, which helps to establi...
Article
Several species of palaemonid shrimps are known to act as fish-cleaning symbionts, with cleaning interactions ranging from dedicated (obligate) to facultative. We confirmed five evolutionarily independent origins of fish cleaning symbioses within the family Palaemonidae based on a phylogenetic analysis and the ancestral state reconstruction of 68 s...
Article
Biological invasions are not only events with substantial environmental and socioeconomic impacts but are also interesting natural experiments, allowing the study of phenomena such as the cultural evolution of bird song following introduction. We took an excellent opportunity to compare the distribution of dialects of the yellowhammer (Emberiza cit...
Article
Groundwater is an extreme environment due to its absence of light, resource scarcity and highly fragmentary nature. Successful groundwater colonizers underwent major evolutionary changes and exhibit eye and pigment loss (troglomorphies). Consequently, their chances of dispersal and survival in the well-connected surface waters are greatly decreased...
Article
Full-text available
The Holocene postglacial expansions offer a possibility to assess how quickly snails, with proverbially slow active dispersal and unclear passive dispersal capabilities, can naturally spread. We explore the possibilities and limitations of such an approach on an iconic European snail. We locate probable sources of postglacial expansion of Helix pom...
Article
The signal crayfish Pacifastacus leniusculus, native to northwestern North America, has become the most widespread invasive crayfish species in Europe. It has been introduced repeatedly since 1959, and altogether >60,000 individuals were imported. Secondary introductions across the continent followed, resulting in its current presence in ≥26 Europe...
Article
Full-text available
Background: Genetically divergent cryptic species are frequently detected by molecular methods. These discoveries are often a byproduct of molecular barcoding studies in which fragments of a selected marker are used for species identification. Highly divergent mitochondrial lineages and putative cryptic species are even detected in intensively stud...
Article
Full-text available
Aphanomyces astaci, the crayfish plague pathogen, is responsible for mass mortalities in native European crayfish stocks. Its persistence and spread across Europe has been facilitated by the presence of invasive North American crayfish species, which act as asymptomatic vectors of this pathogen. In France, some recent mass mortalities have involved...
Article
Full-text available
Established populations of the non-indigenous parthenogenetically reproducing marbled crayfish Procambarus fallax f. virginalis have been recently reported from various European countries. The colonised sites are usually lentic and relatively isolated from major watercourses and in such cases the immediate threat of the spread of this taxon is limi...
Article
Although the introduction of the crayfish plague pathogen Aphanomyces astaci to Europe is responsible for substantial declines in native crayfish populations throughout the whole continent, its presence has never been officially confirmed in many European regions, including most of the Balkan Peninsula. We demonstrate that the recent crayfish morta...
Article
Full-text available
The amphipod genus Niphargus comprises hundreds of eyeless and depigmented species with narrow ranges in Western Palaearctic subterranean freshwaters. N. hrabei and N. valachicus, two morphologically and ecologically similar species, are atypical due to their epigean lifestyle and large ranges. Given their wide and largely sympatric distributions,...
