Summary: Pharmaceutically active compounds are common and increasing in the aquatic environment, and have adverse effects on non-target organisms. This study analyzed the effects of psychoactive compounds on marbled crayfish and found that even low concentrations of these chemicals can modify the physiological state of aquatic animals without outward manifestations. Further research is needed to investigate the broad impact of environmental pharmaceuticals and their combinations on aquatic organisms.

Summary: The burden of environmentally transmitted infectious diseases on humans is strongly influenced by ecological factors. The marbled crayfish is an invasive species that can adapt to various ecological conditions and habitats. It has been hypothesized that the marbled crayfish may serve as a predator of schistosome-competent snails, which are the intermediate hosts of schistosomiasis. However, there has been no systematic study to estimate its predation rate on snails. In this study, we experimentally assessed marbled crayfish consumption of snails across a range of temperatures and found that temperature and crayfish weight influenced the predation rates.

Summary: The study characterized the effects of deltamethrin onDNA damage, immune response, and neurotoxicity in P. clarkii. The results indicated that deltamethrin induced DNA damage, immunotoxicity, and neurotoxicity inP. clarkii by excessive generation of ROS. The dose-dependent responses of parameters under exposure of deltamethrin at environmentally realistic concentrations suggest that these parameters could be used as sensitive biomarkers for risk assessment of deltamethrin in aquaculture.

Summary: This study examined the effects of reproductive state and temperature on the functional response of marbled crayfish. The results showed that gravid individuals had a lower rate of prey consumption compared to non-gravid individuals, and non-gravid individuals exhibited an increase in attack rate and a reduction in maximum feeding rate at higher temperatures. Furthermore, warming influenced the reproductive cycles of the crayfish, increasing the frequency and duration of gravid states.

Summary: Vibrio parahaemolyticus is a common foodborne pathogen primarily found in seafood, but recent research has discovered its presence in freshwater crayfish as well. The strain isolated from freshwater crayfish showed higher pathogenicity and lacked known virulence marker genes compared to clinical strains. This strain also displayed multidrug resistance. The study highlights the potential transmission of hypervirulent V. parahaemolyticus through freshwater food products and suggests the use of a phage cocktail as a promising method for control.

Summary: Invasive alien crayfish pose a threat to freshwater ecosystems and native crayfish species. This study found that while repeated infection with the crayfish plague can reduce growth rates, the marbled crayfish has resistance to the pathogen and its survival is mainly affected by food limitation. These findings suggest that the marbled crayfish has the potential to become a successful freshwater invader.

Summary: The presence of North American alien crayfish in Europe has led to declines in native crayfish populations due to their role as carriers of Aphanomyces astaci, the pathogen responsible for crayfish plague. In Czechia, screening for A. astaci revealed new hotspots of infected crayfish and the potential for interspecific transmission between different crayfish species. Despite fluctuations, A. astaci prevalence in North American host populations generally does not vary significantly over time, with some populations still posing a threat to native crayfish.

Summary: The study found that the decline of native crayfish biodiversity caused by invasive crayfish introductions has been well documented, but the fate of their associated biota has been overlooked. The presence of native European branchiobdellids (annelid worms that are ectosymbionts of crayfish) was monitored in three localities in Czech Republic. The results showed that branchiobdellids were not detected in areas with invasive signal crayfish but without the native noble crayfish, and the number of branchiobdellids on signal crayfish was significantly lower compared to the native noble crayfish.

Summary: The killer shrimp Dikerogammarus villosus is an invasive alien amphipod that has spread across freshwater rivers and streams in Europe, causing ecological and economic impacts. Our study analyzed 96 European time series and identified trends in the population dynamics of D. villosus, as well as its impact on ecological communities. We found that D. villosus is well-established in European waters and its abundance significantly alters recipient community metrics. However, early detection methods are needed to address the cryptic initial introductions of D. villosus.

Summary: The postglacial recolonization of four Central European land snail species was facilitated by persistence close to the colonized areas rather than by dispersal ability allowing for colonization from distant sources. The most important source of postglacial expansions to Central Europe was refugia located adjacent to the Pannonian Basin, but there were also substantial southward expansions. Climate factors and biological interactions may explain the rarity of such southward expansions in Europe.

Summary: Crustacean hemocytes play important roles in immune functions such as coagulation and phagocytosis. In this study, we used in situ approach and transmission electron microscopy technique to investigate the ultrastructural behavior of hemocytes during coagulation and phagocytosis in marbled crayfish. Our findings showed drastic morphological changes of hemocytes during coagulation, including the transformation of cytoplasmic granules and the involvement of nucleus. We also observed the uptake of necrotic tissues by phagocytic hemocytes and the incorporation of digested contents into cellular components, affecting the cell morphology.

Summary: Since the mid-20th century, Europe has seen a significant increase in non-indigenous crayfish species (NICS) due to their extensive use in fisheries, aquaculture, and pet trade. However, there is a lack of large-scale analysis on their occurrences and trends. In this study, using a freshwater macroinvertebrate database, we evaluated the information on NICS obtained from biomonitoring approaches and identified species-specific trends. We found no significant temporal trend for the abundance of any species at the European scale but identified predictors of abundances.

Summary: Using stable carbon and nitrogen isotope analysis to assess trophic interactions in freshwater ecosystems provides insight into ecosystem functioning, but the variability of isotope values driven by environmental fluctuation is poorly understood. This study investigated the temporal variation of stable isotopes in consumers of a canyon-shaped oligotrophic reservoir and its association with environmental factors. Results showed significant differences in delta C-13 and delta N-15 values in each consumer among studied years. The flooded area of the reservoir was a major driver of delta C-13 stable isotope values variation in consumers.

Summary: Biological invasions pose a growing threat to ecosystems, biodiversity, and socio-economic interests. However, there are variations in classifications and definitions of invasive species among European Union member states, leading to differences in the number and proportion of reported invasive species. Using Germany as a case study, this research highlights the gaps in invasive species classifications and suggests that the lower number of reported invasive species in Germany may be attributed to differences in classifications, variations in research effort and focus, and diverse national priorities. This underreporting may be a result of a focus on economic growth, which may have taken precedence over addressing the potential ecological and economic impacts of invasive species.

Summary: There is a lack of research and data on the presence, impacts, and management implications of potentially invasive Orthoptera species in Europe, hindering the development of effective management strategies. To address this gap, there is a need for increased efforts to collect and curate data on non-native and possibly invasive Orthoptera in Europe. These efforts will enhance our understanding of their invasion dynamics and facilitate conservation prioritization and effective management policies.

Summary: Dialects are a common form of geographic variation in birdsong, which provide opportunities for focused studies on vocalization spatial patterns. The Yellowhammer has been a subject of citizen science projects that focus on its dialect distribution, with the most successful project being the Dialects of Czech Yellowhammers (DCY). In this study, we quantitatively analyzed the variation in the terminal song element of three dialects defined in DCY and found that pooling them into two distinct groups better reflects the variation in the songs and their spatial distribution.

Summary: The aquarium pet trade is a source of potentially invasive crayfish species that can be introduced into new environments, posing a threat to native biodiversity and freshwater ecosystem functioning. Europe, particularly Serbia, is experiencing an increase in invasive crayfish species, such as the marbled crayfish and the red swamp crayfish, traded as ornamentals. The presence of these species in the pet trade could lead to their occurrence in the wild.
