The amphipod Dikerogammarus villosus has colonized most of the European main inland water bodies in less than 20 years, having deteriorating effect on the local benthic communities. Our aim was to reveal the species phylogeography in the native Black Sea area, to define the source populations for the colonization routes in continental Europe and fo...

1. The effects of biological invasions are generally more detrimental in isolated ecosystems than in the interconnected ones and freshwater lakes appear to be particularly fragile. The Ponto-Caspian freshwater amphipod Dikerogammarus villosus (Gammaridae), also known as the killer shrimp, is a highly invasive species that can have significant ecolo...

Full-text available
The 'killer shrimp', Dikerogammarus villosus, has been recognised as one of the 100 worst alien species in Europe, in terms of negative impacts on the biodiversity and functioning of invaded ecosystems. During the last twenty years, this Ponto-Caspian amphipod crustacean has rapidly spread throughout Europe's freshwaters and its invasion and contin...
Article
The alien freshwater amphipod of Ponto-Caspian origin, Dikerogammarus villosus, also known as the killer shrimp, is recognized as being one of the worst invasive alien species in Europe, representing a major conservation problem. Recently, the species has been reported to invade lakes in the Alps in putative association with overland transport lin...

Background: The Balkans are a major worldwide biodiversity and endemism hotspot. Among the freshwater biota, amphipods are known for their high cryptic diversity. However, little is known about the temporal and paleogeographic aspects of their evolutionary history. We used paleogeography as a framework for understanding the onset of diversificatio...

Full-text available
Dikerogammarus villosus (Sowinsky, 1894) is a Ponto–Caspian amphipod expanding in European freshwaters and posing a threat to biological diversity through several biological and behavioural traits, including high carnivory and voracity. The species spreads in Europe through two major corridors from two geographically and genetically different sourc...

Full-text available
Ponto-Caspian gammarids comprise dozens of endemic taxa. Many are invasive throughout the world, being exceptionally adaptable thanks to the dynamic geological history of the region where they have evolved. Many species described from the Caspian basin were found in the Pontic (Black Sea) basin only in the last century. It remains unclear whether t...

Background Chironomidae, with over 7,300 described species, are amongst the most diverse and abundant insect families in freshwater ecosystems worldwide. Chironomids are known for their widespread distribution from various water types. The level of documentation of chironomid fauna varies considerably amongst European countries, with more comprehen...

The mitochondrial genome of Metazoa is predominantly maternally inherited, providing a valuable genetic marker in various fields such as phylogenetics and phylogeography. However, mitochondrial heteroplasmy, where multiple copies of mitochondrial DNA (mtDNA) coexist within an individual or even cell, presents a challenge to the use of mtDNA markers...

Amphipods have diversified greatly in the Ponto-Caspian region. Although many of these species are prominent invaders their systematics remains unclear. Taking an integrative approach, we investigate the taxonomy of Trichogammarus trichiatus, a widespread invader in European inland waters. It was initially described from the northeastern Black Sea...

The Ponto-Caspian amphipod Dikerogammarus bispinosus Martynov, 1925 was originally described from the Black Sea basin. Its recent discovery in the Caspian Sea basin was puzzling because it was unknown whether it was an invasive or an overlooked native species in this area. Here, we examined specimens collected from both the Black and Caspian Sea ba...

Full-text available
The importance of aquaporins (AQPs) in the transport of water and solutes through cell membranes is well recognized despite being relatively new. To date, despite their abundance, diversity, and presence in disparate environments, amphipods have only been mentioned in studies about the AQPs of other animals and have never been further investigated....

Full-text available
The Ponto-Caspian region is the main donor of invasive amphipods to freshwater ecosystems, with at least 13 species successfully established in European inland waters. Dikerogammarus spp. and Pontogammarus robustoides are among the most successful, due to their strong invasive impact on local biota. However, genomic knowledge about these invaders i...

Background. Dragonflies and damselflies (Odonata) are important components in biomonitoring due to their amphibiotic lifecycle and specific habitat requirements. They are charismatic and popular insects, but can be challenging to identify despite large size and often distinct coloration, especially the immature stages. DNA-based assessment tools re...

Gammarus roeselii Gervais, 1835 is a morphospecies with a wide distribution range in Europe. The Balkan Peninsula is known as an area of pre-Pleistocene cryptic diversification within this taxon, resulting in at least 13 Molecular Operational Taxonomic Units (MOTUs). The morphospecies diversified there during Neogene and has probably invaded other...
Article
Full-text available
Traditional morphological diagnoses of taxonomic status remain widely used while an increasing number of studies shows that one morphospecies might hide cryptic diversity, i.e. lineages with unexpectedly high molecular divergence. This hidden diversity can reach even tens of lineages, i.e. hyper cryptic diversity. Even well-studied model-organisms...

Background. Small size and large diversity of adaptations make invertebrates a group of animals which can be easily transported by different human activities. Many species can travel as “hitchhikers” with plant material (both on plant surfaces and in the soil), including plants used for decoration in vivaria. Vivaria are often tropical in nature en...
