Purpose. To investigate the long-term dynamics of commercial catches of Leuciscidae in the Dnipro Reservoir and to determine sustainable catch limits as an aquatic bioresource. Methodology. The study was conducted in 2024–2025 at three commercial fishing areas of the Dnipro Reservoir (central part, lower part, Samara Bay), which differed in hydrology, ecology, and the level of human impact. Classical ichthyological methods were used. The study objects were members of the family Leuciscidae: common bream, chub, asp, roach, silver bream, blue bream, sabrefish, rudd, white-eye bream, vimba, and bleak. The analysis included species composition of commercial catches, age and size structure of fish populations, condition factors, catch dynamics over long-term series, and official commercial statistics (2014–2024). Findings. It was found that Leuciscidae species account for 54.1% of total catches in the Dnipro Reservoir cascade, with common bream, roach, and bleak being the main commercial species. Populations of these species are characterized by stable abundance and biomass. Based on biological and fishing parameters, fish stocks and catch limits for the Dnipro Reservoir in 2026 were calculated. Originality. For the first time in the Dnipro Reservoir, a comprehensive analysis of Leuciscidae commercial stocks was conducted, incorporating long-term data series, spatial-temporal population characteristics, and mortality coefficients. Differentiated fishing regimes for specific reservoir areas were proposed. Practical Value. The results allow optimization of fishery management, ensuring sustainable use of resources and biodiversity conservation, reducing the risk of stock depletion, and supporting the stability of commercial fishing. The proposed recommendations were used as the basis for establishing fish catch limits in the Dnipro Reservoir in 2026. [ABSTRACT FROM AUTHOR]

Despite the breakthrough achievements in understanding structural and functional alterations of brain connectivity in autism spectrum disorder (ASD), the exact nature and type of such alterations are not yet clear due to conflicting reports of hyper-connectivity, hypo-connectivity, and—in some cases—combinations of both. In this work, we bring order to the debate using a network comparison technique to capture mesoscopic-scale differential patterns of functional connectedness. In particular, we leverage recent algorithmic advances in extracting contrast subgraphs to identify maximally different mesoscopic connectivity structures between two sets of networks from typically developed individuals and ASD subjects across different developmental stages. A significantly larger connectivity among occipital cortex regions and between the left precuneus and the superior parietal gyrus was found in ASD subjects. At the same time, reduced connectivity characterized the superior frontal gyrus and the temporal lobe regions. More importantly, our results reconcile within a single framework multiple previous separate observations about functional connectivity alterations in ASD.

Recently, China has undergone rapid urbanization in terms of population and urban land growth. However, there are notable lags in the people-oriented dimensions of urbanization, including urban social services, environmental services, and socioeconomic equity, which are crucial for achieving SDG11 (sustainable cities and communities). Here, considering the complex dimensions of urbanization, we examined 16 people-oriented urbanization indicators across four dimensions, namely, economic, social, environmental, and equity dimensions, from 2005 to 2020, and their relationships with population/land urbanization at multiple scales (national, regional, and urban agglomeration scales), and among different city sizes, via the paired t test and the evenness index. Notably, between 2005 and 2020, these urbanization indicators of China showed an overall upward trend, with changes ranging from 1.09 to 53.95 times. Among the 16 people-oriented urbanization indicators, the economic and social indicators lagged behind the land and population urbanization, whereas the environmental indicators caught up. The evenness index among these indicators showed a U-shaped change pattern, which indicated that people-oriented urbanization was coming up with population/land urbanization since the implementation of China new-type urbanization plan in 2014 until 2020. In the future, increasing investment in social service systems and implementing place-based coordination strategies are necessary to make cities inclusive, safe, resilient, and sustainable.
