Summary: The loss of biodiversity highlights the importance of understanding its impact on ecosystem function. This study investigated the effects of temperature on resource acquisition and assimilation for freshwater mussel species. The results showed thermal sensitivity in certain species and temporal variations in their contribution to ecosystem function under different temperature and flow regimes. River discharge and nutrient concentrations were found to modulate the impact of mussel community on ecosystem functioning. The study emphasizes the need to consider species-specific traits in assessing the role of biodiversity in ecosystem function.

Summary: Freshwater mussels are ecosystem engineers that can alter habitats and impact biodiversity. We studied the associations between two species of subtropical freshwater mussels and macroinvertebrate communities in a polluted urban lake in Bangladesh. We found that mussel density was correlated with macroinvertebrate community composition, highlighting the importance of species identity in shaping communities.

Summary: This study evaluated the exposure of mussels to various contaminant stressors in different sections of the Clinch River, finding that organic contaminants, especially PAHs, were related to mussel decline, while metals were largely unrelated. Results indicated that PAHs and Mn were key pollutant stressors in the Clinch River, mainly coming from the Guest River tributary watershed.

Summary: The Eastern Mediterranean region is characterized by high diversity and endemism of freshwater mussels, with over 70% more Unionidae species than previously assumed. Two new species were proposed, along with re-descriptions and reclassifications of existing taxa. Phylogeographic patterns were interpreted in the context of past geological events, and conservation priorities and implications were presented.

Summary: Parasites can indirectly affect ecosystem function by altering the clearance rates of their hosts, and different parasites have contrasting impacts on host clearance rates; the infection patterns and individual effects of parasites need to be considered; the presence of parasites can significantly alter ecosystem processes, thus the impact of parasitism should be taken into account in future studies on ecosystem function.

Summary: The decline of native unionid mussels has led to an increase in invasive hybridisation between native and introduced bitterling fish species, as they compete for breeding substrate. The rapid decline of host mussel species and introduction of an invasive congener interact to cause a cascade of extinctions in native species, with obligate parasite species being threatened by the disappearing host species.

Summary: Similar to other aquatic ectotherms, freshwater mussels are prone to the predicted global warming of surface waters. Sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA) has a crucial role in regulating intracellular Ca2+ concentration in muscle cells and potentially involved in setting thermal preferences and behaviors of animals. SERCA activity of adductor and foot muscles in two freshwater mussel species, Anodonta anatina and Unio tumidus, was examined under different acclimation temperatures. The results showed significant differences in SERCA activity between the two species and different tissues. Cold-acclimated individuals tended to conserve energy by turning off SERCA activity in the muscular foot. Strong temperature-dependent up- or down-regulation of muscle SERCA activity in mussels is probably associated with species-specific behaviors and has implications on freshwater mussel aquaculture and conservation.

Summary: This study examined temporal variation in the microbiomes of six freshwater mussel species sampled in 2016 and 2019, finding significant differences in most species between the two years. However, not all species showed functional differences, indicating functional redundancy within the microbiome. Inferred biosynthesis pathways demonstrated temporal variation in degradation pathways, while pathways related to cellular metabolism remained stable. These results suggest that temporal variation plays a key role in shaping the gut microbiomes of freshwater mussels and support the involvement of these microbiomes in host development and activity.

Summary: Near-bottom suspended sediments contain higher concentrations of organic carbon, nitrogen, phosphorous, and metals compared to bottom sediments. The smaller grain size of suspended sediments makes it easier for freshwater mussels to catch them. The main source of suspended sediments in the Tisza River is soil-derived organic materials, which contain more biofilms and organic nutrients, as well as metal ions bound as complexes or chelates. Only the concentration of mercury exceeded the probable effect concentration based on the guidelines for evaluating potential risk of metal contaminants in sediments.

Summary: Accurate species identification is crucial in ecology and evolutionary biology. The mtDNA-based classification of unionid mussels Beringiana and Sinanodonta may not be reliable due to inconsistencies between mitochondrial and nuclear DNA phylogenies. Shell morphology alone is insufficient for species identification, as parallel appearances of similar shell forms were observed in the two genera in Lake Biwa.

Summary: The co-culture production of giant gourami and Azolla filiculoides was tested in this study, and it was found that the production cycle of Azolla did not match with that of the fish. Despite having no impact on water quality, both systems were economically unbeneficial due to high costs and sub-optimal feed performance.

Summary: Global warming is expected to increase heatwaves in fish farms, leading to more frequent and intense occurrences of acute hyperthermia and hypoxia in fish. These conditions can result in growth losses, increased pathogens pressure, and mortality. Selective breeding shows promise in improving resistance to non-optimal water quality, but the specific traits need further characterization before inclusion in selection programs. This study found significant variation in resistance to acute hyperthermia and hypoxia among genotypes of rainbow trout, with stability in rankings observed over a year. There was no overall relationship between resistance to these two stressors, suggesting no strong genetic trade-offs.

Summary: This study aimed to investigate the correlations between fish feed efficiency (FE) and potential predictive criteria in rainbow trout. The results showed significant correlations between feed conversion ratio (FCR) and residual feed intake (RFI) with feed intake, but no significant association was found with body weight variations as a predictive criterion. In addition, a strong positive correlation was found between the number of feed demands in feeding behavior and RFI. Overall, this study provides guidance for the aquaculture industry in assessing feed efficiency in fish.
