Rivers suffer from multiple stressors acting simultaneously on their biota, but the consequences are poorly quantified at global scale. We evaluated biological condition of rivers globally, including largest proportion countries Global South published to date. gathered macroinvertebrate- and fish-based assessments 72,275 37,676 sites, respectively, 64 study regions across six continents 45 nations. Because were based differing methods, different systems consolidated into a 3-class system:...
Nine new species belonging to the Pholcus phungiformes-group are described from Korea, viz., chugok Lee & Lee, sp. nov., noeun wonju ungyo hwangjeong gimsatgat solchi mino and maepo nov. These were found mountainous habitats in Gangwon-do Chungcheongbuk-do, northeastern regions of South Korea where two major mountain ranges (Taebaeksan mountains Sobaeksan mountains) located together. Detailed descriptions, photographs, a distribution map for provided with notes on their intraspecific...
Abstract Outbreaks of Asynapta groverae , an invasive mycophagous gall midge, in South Korea have been repeatedly reported since the first occurrence 2008. This species is a nuisance to residents owing its mass emergence from newly built and furnished apartments. Here, levels genetic diversity, divergence, structure A. populations were investigated understand their ability survive novel locations. Population analyses performed on seven populations, including outbreak, sporadically emerged,...
Most large rivers in South Korea run through major cities, which often experience many environmental problems, including outbreaks of non-biting midges (Diptera: Chironomidae). However, chironomid species inhabiting have not been thoroughly investigated. We aimed to identify collected from the four main Korea, construct a corresponding DNA barcode library, and examine distribution community structure identified riverine species. Adult chironomids were nine sites along by using sweep nets...
The nonbiting midge, Glyptotendipes tokunagai Sasa (Diptera: Chironomidae), is an organism that can be used as a water quality indicator. Development of this insect under different temperatures was evaluated. highest egg hatching rate 99.12 ± 1.47% at 30°C, and the lowest 84.50 11.09% 10°C. No eggs hatched 8 42°C. Developmental (1/h) increased gradually temperature from 10 to 35°C with peak (0.045 0.0079) 35°C. estimated lower thermal threshold for 9.3°C. Adult emergence (80.6%) 30°C (22.2%)...
Abstract Sciaroidea is a megadiverse clade within Diptera that exhibits diverse larval feeding modes. In this study, we explored the phylogenetic relationships and evolution of modes superfamily using fossil-calibrated time tree. We found filtering out potentially fast-evolving sites altered family-level tree topology, species incertae sedis might be crucial in determining general topology. The most recent common ancestor was inferred to have originated Upper Triassic (~225 Ma). A major...

As a consequence of the climate change, localized torrential rainfall has increased in intensity and frequency Northeast Asia. This work aims at studying effect on benthic macroinvertebrate communities mid-sized mountain stream Korea, where summer monsoon flood is prevalent. Sampling was conducted along reaches Gapyeong (42 km length), central Korean Peninsula, from period July 2008–October 2009. The sampling collection carried out within 48 h after every major rain occasion quantified by...
Once metal-based engineered nanoparticles (NPs) are released into the aquatic environment, they expected to interact with other existing co-contaminants. A knowledge gap exists as how interaction of NPs co-contaminants occurs. Here we selected ZnO among various NPs, Ag ion a contaminant in environment by widely used. novel modeling strategy was demonstrated enabling quantitative and predictive evaluation aqueous mixture nanotoxicity. Individual binary toxicity tests silver (as AgNO3) on...
Abstract The C heonggyecheon ( heonggye stream), a downtown stream in S eoul, K orea, was restored by the historic Restoration Project (2003–2005), and its discharge other environmental conditions are artificially regulated throughout year. aim of this study to assess temporal changes benthic macroinvertebrates their interactions with fish predators heonggyecheon. Sampling conducted twice year (spring autumn) at three sections from 2006 2010 using Surber sampler (50 × 50 cm) for cast net...
We investigated the drought effects on colonization rate and pattern of benthic macroinvertebrate communities in newly created mesocosm wetlands central Korean Peninsula, from June 2011 to 2013. The comparison was made between initial after construction (pre-drought) recolonization a event (post-drought) with period 50 days them. In addition, we categorized according their biological traits relation drought. Our results showed that aquatic vegetation abundance covering degree were higher...
Members of the nonbiting midge family Chironomidae have been used worldwide as water-quality indicators or toxicity test organisms. The purpose this study was to establish chironomid Glyptotendipes tokunagai Sasa a new species by conducting successive rearing under laboratory conditions. We monitored biological and genetic aspects >42 generations over 7 yr, also compared development 39th generation with fourth five constant temperatures 15, 20, 25, 30, 35°C. observed that number eggs in an...
Chironomid larvae are among the dominant benthic macroinvertebrates in all types of water systems South Korea. They may pass through pipes rivers (raw water) and occur drinking water, thus creating public health issues. However, little is known about larval stages chironomids large Korean rivers. Therefore, we examined larval–adult associations inhabiting major used as sources. The were collected 2015 2016 from nine locations along four largest Korea using a Ponar grab. Cytochrome oxidase...
Researchers have gained new therapeutic insights using multi-omics platform approaches to study DNA, RNA, and proteins of comprehensively characterized human cancer cell lines. To improve our understanding the molecular features associated with oncogenic modulation in cancer, we proposed a proteogenomic database for lines, called Protein-gene Expression Nexus (PEN). We expanded characterization lines include genetic, mRNA, protein data 145 from various public studies. PEN contains proteomic...
The genus Hexatoma Latreille, 1809 is a large group of aquatic crane flies, with almost 600 species worldwide. largest subgenus Eriocera Macquart, 1838, which includes all nine known from the Korean Peninsula. Molecular methods were used to associate larvae their putative adult South Korea. Mitochondrial Cytochrome c Oxidase Subunit I (COI) gene fragment sequences (DNA barcodes) recently collected adults H. (E.) gifuensis, ilwola, pernigrina, and pianigra compared twelve larvae. pianigra,...
