In the last decade, phylogenetic relationships within genus Triplophysa have become controversial, due to a lack of molecular data. The mitochondrial genome plays vital role in reconstruction and revealing evolution bony fishes. Herein, we obtained complete mitogenome bombifrons via HiFi reads Pacbio Sequel II system DNBSEQ short-reads. We compared all available mitogenomes reconstructed phylogeny Nemacheilidae, based on mitogenomes, using maximum likelihood (ML) methods. results show that...

In this study, we investigated how changes in salinity affect biodiversity and function 11 typical water bodies the Altai region. The of freshwater ranged from 0 to 5, brackish salinities 5 20, hypersaline environments had > 20. We identified orders, 34 families, 55 genera 3061 benthic samples classified them into 10 traits 32 categories. Subsequently, conducted Mantel tests canonical correlation analysis (CCA) calculated functional diversity indices for each sampling site. results...

Abstract Triplophysa yarkandensis , a species of freshwater fish endemic to Xinjiang, China, is currently classified as endangered.

In this study, the composition and structure of macrobenthic community in Ulungu River Basin was investigated water quality status basin evaluated. May August 2022, October 2023, environmental factors at 11 sample sites were investigated, evaluated by Shannon–Wiener index, FBI, BMWP index. A total 6101 organisms collected; these belonged to 3 phyla, 7 classes, 14 orders, 57 families, 117 genera. Arthropod species accounted for largest number (87.9%). nine dominant found: Micronecta sp.,...

Schizothoracinae species are the largest group of Cypriniformes that readily adapt to natural conditions Qinghai-Tibet Plateau. This has habitat characteristics and distribution patterns centered on To study evolution three in Northwest China, evolutionary these were explored based differences otolith morphology skeletal morphology.

Artificial water bodies in Central Asia offer unique environments which to study plankton diversity influenced by topographic barriers. However, the complexity of these ecosystems and limited comprehensive studies region challenge our understanding. In this study, we systematically investigated environment parameters phytoplankton community structure surveying 14 artificial waters on southern side Altai Mountains northern sides Tianshan Xinjiang region. The survey covered physical nutrient...

Little is known about how changes in the biodiversity and functional traits of macroinvertebrates rivers respond to responses anthropic pressures their driving factors. Macroinvertebrates were sampled at 17 sites Irtysh River Basin classified into 10 38 categories between May August 2022. Then, we performed R-mode linked Q-mode (RLQ) analysis calculated richness, evenness, divergence, Rao's quadratic entropy (RaoQ) for each site community-weighted means trait category.
