Summary: Understanding biotic interactions is crucial for species distribution, ecosystem functioning, and conservation efforts. This study presents a new framework to incorporate biotic interactions into conservation planning using freshwater mussels and fish interaction as a case study. Results show that considering both freshwater mussels and fishes in spatial prioritisation is necessary to accurately represent biotic interactions.

Summary: This study reveals the impact of hydroelectric dams on the Wolastoq | Saint John River in New Brunswick, Canada, which restricts the habitat of fish and their parasitic mussel larvae. However, despite this restriction, the number of affected fish species has significantly increased. The research provides critical baseline data on symbiotic interactions in this river ecosystem and highlights the complexity of current management plans for river regulation and fish passage.

Summary: The glochidia of the freshwater pearl mussel show local adaptation by being more successful when attached to local salmonid strains. Therefore, conservation programs should prefer local, sympatric fish strains as hosts for captive breeding of juvenile mussels. Restoration of original salmonid populations is also important for promoting the recovery of endangered freshwater pearl mussel populations.

Summary: Our study used high-resolution, multivariate ecological niche modeling to test the ecological differentiation between two potentially threatened mussel species in East Texas. The results showed that these two species were not ecologically different, consistent with other studies. By ground-truthing the modeling approach, we were able to accurately distinguish suitable habitat and identify new records. This approach has implications for riverine environment research and conservation science.

Summary: This study investigated the parasitic fauna of ornamental fish from seven farms in the East Azerbaijan province in northwestern Iran. The results showed that 26.33% of the examined fish were infected with parasites, with protozoan and monogenean trematode being the most common. In addition, goldfish had a higher infection rate of crustacean arthropods. The assessment of farmed fish parasitic fauna is crucial for preventing infection spread, ensuring fish production, and improving fish health.

Summary: The study found that infection with glochidia has a subtle effect on the growth of fish hosts, leading to significantly lower weight gain in infected fish compared to controls, but without causing host mortality. This suggests that public opinion may become more favorable for the conservation of Margaritifera margaritifera, despite the importance of the salmonid host population for commercial or recreational fishing.

Summary: We provide evidence that the freshwater parasitic copepod, Salmincola californiensis, can act as a vector for the bacterium Aeromonas salmonicida. Through various experiments, we found that fish infected with copepods developed furunculosis caused by A. salmonicida. We also detected fluorescently labelled A. salmonicida in copepod egg sacs and successfully cultured the bacterium from egg sacs collected from infected adult Chinook salmon in a freshwater hatchery.

Summary: This study reports the occurrence of metacercariae of Isoparorchis hypselobagri in cultured food fish Ompok bimaculatus in India. Identification was done through morphology and molecular techniques. The infection patterns were recorded and the influence of host size, season, and water quality on infection rate was tested. The presence of parasites poses a threat to fish production and consumer acceptance, and control of snail vectors is important for prevention of parasitic diseases in cage culture.

Summary: The study found that parasite community structure varied significantly among three riverine fish species, with three-spined stickleback hosting the most ectoparasites, topmouth gudgeon hosting the least parasites, and stone loach hosting the most endoparasites. Factors such as host density, nutrients, temperature, and host size can influence parasite infection among different host species.

Summary: Anthropogenic freshwater habitats offer potential for long-term conservation of freshwater mussels, but may also act as ecological traps. These habitats are not a cure-all for conservation problems, and more research is needed to understand the trade-offs between human use and conservation within them.

Summary: The study found that sea trout in areas with high salmon farm densities on the West coast of Norway had lice infestation rates exceeding 50%, and even in areas with salinities below louse tolerance levels, there were still high lice infestation rates, indicating possible infections elsewhere. This suggests that sea trout are at a higher risk of lice infestations from industrial salmon farming, raising concerns about the environmental sustainability of current aquaculture practices in intensive farming areas.

Summary: A new genus and species of crangonyctid amphipod, Sicifera cahawba gen. & sp. nov., was discovered and described in Dallas County, AL, USA. Comparisons were made between morphological and molecular data of similar crangonyctids, and four species delimitation models were applied, confirming the distinctiveness of this taxon. Additionally, the study revealed that Nearctic members of the crangonyctid genus Synurella form a separate lineage from Palaearctic members, with significant differences in both molecular and morphological markers. This separation suggests a reevaluation of the evolutionary and biogeographical history of these lineages. Furthermore, a key to identifying Nearctic members of the genera Eosynurella/Sicifera was provided.

Summary: Climate changes have significant effects on the distribution of montane lakes and the evolutionary dynamics of cold-adapted species. Past cooling periods have facilitated the dispersion of cold-adapted species through montane lakes, while future warming periods are expected to constrain their distributions. The study on the crustacean Gammarus lacustris using phylogeographic analysis and niche modeling reveals that the species originated in Tian Shan and dispersed to montane lakes along various mountain ranges. Suitable regions for G. lacustris lineages were larger during cooling periods but smaller during warming periods. Future climate warming may force species to shift their distributions, emphasizing the importance of conserving montane lakes.

Summary: Research suggests that genetic distinct populations geographically isolated from each other in desert springs are likely to have independent evolution and separate species status. Additionally, subtle interspecific morphological variation has been observed among putative species. Multiple lines of evidence were used to formally describe four new species endemic to the northern Chihuahuan Desert.
