Summary: This study documents the phototactic responses of different amphipod populations to fluoxetine exposure. The results show that all species exhibit significant photonegative responses, but short-term and long-term exposure to fluoxetine have different effects on photoneutrality. The effects vary among populations and sampling locations, highlighting the species-specific and geographically distinct responses to light.

Summary: The dispersal of alien species is a global problem that poses a threat to native biodiversity. The introduction of non-native parasites and pathogens exacerbates this threat, but this indirect impact has received less attention. In this study, we examined the symbiotic communities of gammarids in different habitats along the Baltic coast of Poland to understand the factors influencing the richness of microorganisms in native and invasive host species.

Summary: Previous studies on the distribution of neuropeptides in the pancrustacean brain have mainly focused on decapod species, while other taxa have received less attention. This study examined the brain and ventral nerve cord of the amphipod pancrustacean Parhyale hawaiensis using immunohistochemistry. The researchers found strong SIFamide-like labeling in various regions of the brain and nerve cord. They also compared their findings to other pancrustaceans and discussed the evolutionary implications.

Summary: This study investigated the ABC transporters in Baikal amphipods and found that these sequences were conservative across different species and congruent with the species phylogeny. The expression system for an amphipod Abcb1/P-glycoprotein was established successfully in Drosophila melanogaster S2 cell line, and the resulting protein showed a high MXR-related efflux activity.

Summary: This study describes two new species of Hyalella from southeastern Brazil, providing information on their morphology, reproduction, and population aspects. The two new species differ in body length and antenna length, and exhibit a weak positive correlation between head size of paired males and females, as well as differences in sex ratio. Additionally, ovigerous females of one species carry more and larger eggs, possibly in response to differences in habitat use.

Summary: A new species, Gammarus ilamensis sp. nov., was discovered and named in Sarab-e-Meimeh, Ilam Province, Iran. Its taxonomic status within the genus was discussed in comparison to 18 known Iranian species and some species from other areas. The new species, G. ilamensis sp. nov., is phylogenetically placed in the G. komareki species complex and can be easily distinguished by several distinctive characters.

Summary: The study revealed a rich subterranean amphipod fauna in the Caucasus region, focusing on the molecular genetic approach to uncover the presence of at least five closely related cryptic species within the N. alasonius taxon. These cryptic species were found to have diverged during the Late Miocene/Early Pliocene and are distributed along the entire Kura River drainage system, suggesting the river played a crucial role in shaping their biogeographic patterns.

Our findings reveal that Ponto-Caspian amphipods are much more widespread in the Baltic area than previously known and highlight the need for more stringent monitoring.

Summary: The dynamic geological history of the Ponto-Caspian region has led to the evolution of a highly adaptable endemic fauna, particularly the amphipod crustaceans of the superfamily Gammaroidea. This group has a diverse range of species and plays an important role in adaptive radiation. The molecular phylogenies suggest that this radiation originated in the mid-Miocene period and is nested within a morphologically conserved clade. The Ponto-Caspian gammaroids exhibit extensive disparity in body characteristics and ecological preferences, making them a potentially powerful model for studying adaptive radiations and invasive species evolution.

Summary: The study revealed the presence of three independent lineages of the Ponto-Caspian amphipod Dikerogammarus bispinosus, each with distinct molecular and morphological characteristics. It was found that D. bispinosus is a native species in the Caspian region, contrary to previous beliefs. The study highlights the importance of further research to fully understand the evolutionary history and taxonomy of this species complex.

Summary: The Ponto-Caspian region is a hotspot for endemic species, with the most diverse group being amphipods. This study used DNA barcoding to classify nearly 60% of known Ponto-Caspian amphipod species and compared the results with morphology-based taxonomy. The findings indicate that DNA barcoding is valuable for clarifying the diversity of Ponto-Caspian amphipods, but further work is needed to resolve taxonomic uncertainties.

Summary: The Ponto-Caspian region is a significant source of aquatic alien species in the Northern Hemisphere, particularly amphipod crustaceans. This study provides a comprehensive summary of the taxonomic and ecomorphological diversity of these alien species, as well as their distribution patterns based on global records. The findings reveal a gradual decrease in diversity with distance from the native region and highlight the influence of anthropogenic factors on the biogeographical patterns.

Summary: Recent discoveries of cryptic diversity among Gammarus fossarum species complex in the Western Carpathians pose a challenge for understanding their coexistence. This study found that the distribution of divergent lineages of Gammarus fossarum was influenced by river network position, altitude, stream width, and anthropogenic stress, but not by mesohabitat flow rates. Despite highly imbalanced lineage ratios, strong prezygotic reproductive barriers exist between the studied lineages, indicating the absence of recent gene flow. The frequent and temporally stable syntopy of these reproductively isolated lineages warrants further research on the processes facilitating their coexistence.

Summary: The Ponto-Caspian region is home to the second most diverse lacustrine radiation of amphipod crustaceans in the world. One of the species in this region, Turcogammarus aralensis, has never been properly described, leading to frequent taxonomic reshuffling. This study provides a full re-description of T. aralensis, determines its phylogenetic position using molecular analysis, and confirms its species status.

Summary: The SE Baltic region is home to a diverse group of alien amphipods from the Ponto-Caspian region. The composition of this fauna has been influenced by three waves of invasion. We conducted a study to determine if there are differences in genetic diversity between the native and invaded ranges, and between deliberately introduced species and those that dispersed on their own. Our findings showed that COI diversity decreased in all species in the invaded range, with a greater decrease in the self-dispersed group. OPS diversity did not change significantly between ranges. Mitochondrial diversity was more geographically structured in the native range, and dominant invasive haplotypes were detected in the native populations of most species. This study provides important insights into the inter-range genetic diversity of Ponto-Caspian invaders, particularly the role of introduction mode.

Summary: Amphipods in the Ponto-Caspian region have diversified significantly. The taxonomy of Trichogammarus trichiatus, a common invader in European inland waters, has been investigated using an integrative approach. Analyses of DNA markers, measurements, and imaging reveal that T. trichiatus and C. tenellus major are distinct species, with the former being an endemic species in the Caucasus and the latter being an invader in Europe. Furthermore, T. trichiatus is unexpectedly nested within Chaetogammarus ischnus, despite morphological and geographical differences. The study also reassigns T. trichiatus to Chaetogammarus and establishes a new genus, Spirogammarus, for C. tenellus major.
