Summary: Sulfate's toxicity to whitefish early development primarily affects fertilization and early embryonic development stages, with decreased fertilization success and embryo survival in high sulfate concentrations. However, the tolerance of whitefish embryos and larvae to sulfate exposure is relatively high, with no significant differences in survival observed between control and sulfate treatments during late embryonic and larval periods. The LC50 values for sulfate indicate its relatively moderate toxicity to whitefish early development stages, comparable to other salmonids.

Summary: The bioaccumulation of pollutants in whitefish organs and their haematological parameters were examined over a 40-year period in Lake Imandra. The study found that whitefish from the historically contaminated area showed significant biological reactions compared to those from the uncontaminated area, even after approximately 20 years of decline in toxic load. The changes in physiological states and adaptive strategies of whitefish may help mitigate the negative effects of metal toxicity and improve gas exchange capacity.

Summary: European whitefish is a highly polymorphic species, and the shape and number of gill rakers are important adaptive traits. Our study in the Murmansk region revealed two morphs of whitefish: sparsely rakered and medium rakered. These morphs have different foraging morphology and diet divergence.

Summary: This study investigated the winter ecology of polymorphic whitefish populations and found that the generalist morph primarily relied on benthic prey, while the pelagic specialist morph primarily relied on pelagic prey. Both morphs experienced a reduction in condition, lipid content, and stomach fullness during the winter compared to the summer, with the pelagic morph showing severe decreases potentially approaching starvation.

Summary: The study found that conservation translocations comprising even a modest number of propagules can successfully capture a high proportion of genetic variation of the host population, and that reduced genetic variation in the translocated population may be mitigated by the emergence of new variation over short time periods.

Summary: Exposure of sperm to nanoplastic particles before fertilization may decrease male fertilization potential and have important transgenerational impacts on offspring phenotype and performance. High concentrations of plastic particles can reduce sperm motility, offspring hatching time, body mass, and impair swimming ability, suggesting significant ecological and evolutionary consequences of nanoplastics pollution in aquatic ecosystems.

Summary: This study revealed the phylogenetic relationships of three coregonid species: vendace, least cisco, and peled, based on nucleotide sequences analysis. The results showed that C. albula and C. sardinella are actually a single species, while peled is closely related to vendace. The reproductive isolation of peled was determined by chromosome rearrangements rather than nucleotide substitutions.

Summary: Floral nectar, the most important floral reward for attracting pollinators, varies significantly in carbohydrate and amino acid composition within and between plant species. Factors such as family-specific structural characteristics and combinations of morphological traits contribute to this variation. The study suggests that nectar nutrient composition is affected by family-specific combinations of morphological traits, highlighting the need for further research on intra- and interspecific variation in nectar quality and its consequences for pollinator behavior.

Summary: Plastic pollution is a major aspect of global environmental issues, which has adverse effects on aquatic organisms and ecosystems. This study investigates the potential influence of nano-sized plastic particles on the reproductive biology and offspring traits of fishes. The results suggest that the exposure of gametes to plastic particles slightly increases the body length of larvae but does not affect embryo mortality, hatching time, and larval swimming performance.

Summary: The study presents the complete mitogenome assembly of Gongronella sp. w5 and reveals substantial differences in mitogenome size, intron number, gene order, and orientation from other Mucoromycota species. This unique mitogenome information enhances our understanding of fungal evolution in Mucoromycota.

Summary: In this study, the taxonomic system of Sanguinoderma was revised based on morphological and multi-gene phylogenetic analyses, leading to the description of a new species, Sanguinoderma leucomarginatum, and the transfer of Amauroderma preussii to Sanguinoderma. The study also highlighted the importance of combining morphological characters and phylogenetic evidence in taxonomy research. Additionally, a key to accepted species of Sanguinoderma was provided.

Summary: The study revealed three different forms of whitefish inhabiting the Olenek River basin, with similar numbers of gill rakers and perforated scales in the lateral line but differences in size and appearance. Analysis of gene sequence variation showed that these whitefish belonged to phylogroups identified in the water bodies of the Taimyr Peninsula.

Summary: A comprehensive study on the D. longispina group from water bodies of southern Siberia summarized data on species diversity, morphological variability, genetic structure, phylogeny, and phylogeography. Several new forms/species unique to Russia were identified, along with their morphological characteristics, phylogenetic relationships, and distribution ranges. Variability in mitochondrial DNA genes suggested different evolutionary scenarios for these cladoceran group in northern Eurasia.

Summary: This study compared the distribution of whitefish haplotypes in the Yenisei and Lena river basins in Siberia, finding two distinct clusters but also shared haplotypes suggesting migration and hybridization events. These events likely occurred when the rivers were connected after the last glaciation.
