ZooKeys 1055: 135–148. https://doi.org/10.3897/zookeys.1055.70117 Abstract To investigate the genetic effects on the population of Coreius guichenoti of dam constructions in the upper reaches of the Yangtze River, we analyzed the genetic diversity and population structure of 12 popula- tions collected in 2009 and 2019 using mitochondrial DNA (mtDNA) control regions. There was no significant difference in genetic diversity between 2009 and 2019P ( > 0.05), but the population structure tended to become stronger. Genetic differentiation (FST) among five populations (LX, BB, YB, SF and JA) collected in 2009 was not significant P( > 0.05). However, some populations collected in 2019 were significantly differentiated (P < 0.05), indicating that the population structure has undergone change. -

Seismicity,Structure and Local Stress Fields Around the Downstream of Jinsha River, Western China
Seismicity,structure and Local Stress Fields around the Downstream of Jinsha River, Western China Zhao Cuiping, Zuo kezhen, Duan Mengqiao, Zhao Ce, Zhou Lianqing The Institute of Earthquake Forecasting, CEA, Beijing, China [email protected] Introduction: In the downstream of Jinsha River, 4 large Focal mechanism and Stress Field dams are built or under construction. Among them, Xiangjiaba CAP and GPAT method are used to invert focal mechanisms and Xiluodu reservoir have been filled since Oct. 2012 and May for earthquakes with magnitude of M≥2.0 from Jan. 2016 to 2013 respectively. Baihetan and Wudongde are under July 2018 recorded by the reservoir network. We obtained construction. In order to monitor earthquake activity around total of 542 focal mechanism solutions. Then we use these reservoirs, a dense seismic network has been operated iterative joint inversion method (IJIM) to invert stress field along the downstream of Jinsha River since Jan. 2016,which for four sub-regions, named as the Xiluodu dam area, the is much denser than before. From Jan. 2016 till July. 2018, Baihetan dam area, the Wudongde dam area, and the more than 10 thousand of earthquakes have been located by Ludian source region, in order to investigate the current the intensive network. It is obvious that small quakes became stress environment and the effect of impoundment. more active and frequent since 2013 and continued till Dec. 2017.

Coreius Guichenoti
www.nature.com/scientificreports OPEN Alterations of the gut microbiome of largemouth bronze gudgeon (Coreius guichenoti) suffering from Received: 25 January 2016 Accepted: 07 July 2016 furunculosis Published: 28 July 2016 Tongtong Li1,2,*, Meng Long1,*, Cheng Ji3, Zhixin Shen4, François-Joël Gatesoupe5, Xujie Zhang1, Qianqian Zhang1, Lanli Zhang1, Yuanli Zhao1, Xinhua Liu1 & Aihua Li1 High-throughput sequencing was applied to compare the intestinal microbiota in largemouth bronze gudgeon either healthy or affected by furunculosis. Proteobacteria, Actinobacteria, Tenericutes, Firmicutes and Bacteroidetes were detected as the predominant bacterial phyla in the gut of both diseased and healthy fish. The abundance of Proteobacteria differed significantly between the two groups of fish, mainly due to the overwhelming prevalence ofAeromonas in the diseased fish (81% ± 17%), while the genus was unevenly spread among the apparently healthy fish (33% ± 33%). The bacterial diversity in the intestine of diseased fish was markedly lower than in healthy fish. Analysis revealed the significant dissimilarity between the gut microbiota of diseased and healthy fish. The bacterial profiles in the gut were further characterized with the 28 phylotypes that were shared by the two groups. In diseased fish, two shared OTUs (OTU0001 and OTU0013) were closely related to Aeromonas salmonicida, their total proportion exceeding 70% of the sequences in diseased fish, while averaging 5.2% ± 4.6% in the healthy fish. This result suggested the presence of healthy carriers of pathogenic A. salmonicida among the farmed fish, and the gut appeared as a probable infection source for furunculosis in largemouth bronze gudgeon. Gut microbiota can play important roles in nutrition and health, and it may be considered as an integral com- ponent of the host1–4. -

Homoplasies, consistency index and the complexity of morphological evolution: Catfishes as a case study for general discussions on phylogeny and macroevolution. Int. J. Morphol., 25(4):831-837, 2007. SUMMARY: Catfishes constitute a highly diversified, cosmopolitan group that represents about one third of all freshwater fishes and is one of the most diverse Vertebrate taxa. The detailed study of the Siluriformes can, thus, provide useful data, and illustrative examples, for broader discussions on general phylogeny and macroevolution. In this short note I briefly expose how the study of this remarkably diverse group of fishes reveals an example of highly homoplasic, complex 'mosaic' morphological evolution.

E-mail: [email protected] Abstract A new species of torrent catfish, Liobargus hyeongsanensis, is described from rivers and tributaries of the southeastern coast of Korea. The new species can be differentiated from its congeners by the following characteristics: a small size with a maximum standard length (SL) of 90 mm; body and fins entirely brownish-yellow without distinct markings; a relatively short pectoral spine (3.7–6.5 % SL); a reduced body-width at pectoral-fin base (15.5–17.9 % SL); 50–54 caudal-fin rays; 6–8 gill rakers; 2–3 (mostly 3) serrations on pectoral fin; 60–110 eggs per gravid female. Key words: Amblycipitidae, Liobagrus hyeongsanensis, New species, Endemic, South Korea Introduction Species of the family Amblycipitidae, which comprises four genera, are found in swift freshwater streams in southern and eastern Asia, ranging from Pakistan across northern India to Malaysia, Korea, and Southern Japan (Chen & Lundberg 1995; Ng & Kottelat 2000; Kim & Park 2002; Wright & Ng 2008). -

BMC Evolutionary Biology (2015) 15:233 DOI 10.1186/s12862-015-0516-9 RESEARCH ARTICLE Open Access Biogeographic history and high-elevation adaptations inferred from the mitochondrial genome of Glyptosternoid fishes (Sisoridae, Siluriformes) from the southeastern Tibetan Plateau Xiuhui Ma1,2, Jingliang Kang2,3, Weitao Chen2,3, Chuanjiang Zhou2 and Shunping He2* Abstract Background: The distribution of the Chinese Glyptosternoid catfish is limited to the rivers of the Tibetan Plateau and peripheral regions, especially the drainage areas of southeastern Tibet. Therefore, Glyptosternoid fishes are ideal for reconstructing the geological history of the southeastern Tibet drainage patterns and mitochondrial genetic adaptions to high elevations. Results: Our phylogenetic results support the monophyly of the Sisoridae and the Glyptosternoid fishes. The reconstructed ancestral geographical distribution suggests that the ancestral Glyptosternoids was widely distributed throughout the Brahmaputra drainage in the eastern Himalayas and Tibetan area during the Late Miocene (c. 5.5 Ma). We found that the Glyptosternoid fishes lineage had a higher ratio of nonsynonymous to synonymous substitutions than those found in non-Glyptosternoids. In addition, ωpss was estimated to be 10.73, which is significantly higher than 1 (p-value 0.0002), in COX1, which indicates positive selection in the common ancestral branch of Glyptosternoid fishes in China. We also found other signatures of positive selection in the branch of specialized species. These results imply mitochondrial genetic adaptation to high elevations in the Glyptosternoids. Conclusions: We reconstructed a possible scenario for the southeastern Tibetan drainage patterns based on the adaptive geographical distribution of the Chinese Glyptosternoids in this drainage. -

E-mail: [email protected] Abstract Pseudobagrus fui Miao is a valid bagrid species that can be separated from all its congeners in having 27–33 anal-fin rays. Among the species of Pseudobagrus, it forms part of a group of approximately 20 species putatively characterized by having a smooth anterior margin of the pectoral-fin spine and short maxillary barbels not extending to the base of the pectoral-fin spine. Pseudobagrus fui, together with P. nitidus and P. vachelli, can be differentiated from all other fork- tailed species of this group by having no fewer than 20 branched anal-fin rays, the posterior end of the anal-fin base posterior to the vertical through the posterior end of the adipose-fin base, and anal-fin base longer than the adipose-fin base. It further differs from P. nitidus in having a gas bladder without beaded lateral and posterior margins, and from P. -
18 State Institution for Plant Protection and Plant Quarantine, His Work On
state institution for plant protection and plant quarantine, his work on aquatic fauna was largely private. However, political restraints in the German Democratic Republic (DDR) permitted no open contacts with colleagues in countries of the Klassenfeind; field work was possible only in socialistic brother states. Among other activities, Dietrich Braasch and his friend, the late Dr. Wolfgang Joost, collected repeatedly in Bulgaria and published a series of faunistic and taxonomic studies on the stoneflies of the country, including descriptions of several new species. The collections of D. Braasch and W. Joost include important stonefly material. The material of Wolfgang Joost is deposited in the Museum der Natur, Gotha, Germany (Perla 23, 2005: 43-48), that of Dietrich Braasch is now in the Museum für Naturkunde, Berlin, Germany. I am grateful to Dr. Wolfram Mey for informing me of the recent transfer. This transfer came to my knowledge immediately before the closing deadline of the present issue of PERLA. Therefore, I refer to published bibliographies of Dietrich Braasch. The laudation at the occasion of his 65th birthday (Joost and Klausnitzer, 1997) lists all 210 publications published at that time, numbers 211-253 are presented by Mey (2016).
