The Status of the Endangered Freshwater Fishes in China and the Analysis of the Endangered Causes Institute of Hydrobiology
The status of the endangered freshwater fishes in China and The analysis of the endangered causes HE Shunping, CIIEN Yiyu Institute of Hydrobiology, CAS, Wuhan, ITubei Province, 430072 Abstract More than 800 species of freshwater fishes are precious biological resources in inland water system of China. Among them, there are a great number of endemic and precious group, and a lot of monotypic genera and species. Recently, owing to the synthetic effects of the natural and human-beings, many of these fishes gradually became endangered. The preliminary statistic result indicates that 92 species are endangered fishes and account for 10% of the total freshwater fishes in China. For the purpose of protection of the biodiversity of fishes, it is necessary to analyse these causes which have led the fishes to become endangered. This report could be used as a scientific reference for researching and saving the endemic precious freshwater fishes in China. Key words Endangered freshwater fishes, Endangered causes, China In the process of the evolution of living things, along with the origin of life, the extinction of life also existed. In the long_ life history, the speciation and the extinction of living things often keep a relative balance. As time goes on, especially after by the impact of human beings activity of production and life, the pattern of the biodiversity were changed or damaged, more or less. At last, in the modern society, human beings activity not only accelerate the progress of society and the development of economy, but also, as a special species, become the source of disturbing_ to other species. -

The fish genera Gasterosteus, Hucho, Oxynoemacheilus, Salmo, and Schizothorax are examples of these groups among vertebrates, and the genera Magnibursatus (Trematoda), Margaritifera, Potomida, Microcondylaea, Leguminaia, Unio (Mollusca), and Phagocata (Planaria), among invertebrates. There is reason to believe that their ancestors spread to Europe through the Paratethys (or the proto-Paratethys basin that preceded it), where intense speciation took place and new genera of aquatic organisms arose. Some of the forms that originated in the Paratethys colonized the Mediterranean, and overwhelming data indicate that Citation: Artamonova, V.S.; Bolotov, representatives of the genera Salmo, Caspiomyzon, and Ecrobia migrated during the Miocene from I.N.; Vinarski, M.V.; Makhrov, A.A. -
Dressing for the Times: Fashion in Tang Dynasty China (618-907)
Dressing for the Times: Fashion in Tang Dynasty China (618-907) BuYun Chen Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2013 © 2013 BuYun Chen All rights reserved ABSTRACT Dressing for the Times: Fashion in Tang Dynasty China (618-907) BuYun Chen During the Tang dynasty, an increased capacity for change created a new value system predicated on the accumulation of wealth and the obsolescence of things that is best understood as fashion. Increased wealth among Tang elites was paralleled by a greater investment in clothes, which imbued clothes with new meaning. Intellectuals, who viewed heightened commercial activity and social mobility as symptomatic of an unstable society, found such profound changes in the vestimentary landscape unsettling. For them, a range of troubling developments, including crisis in the central government, deep suspicion of the newly empowered military and professional class, and anxiety about waste and obsolescence were all subsumed under the trope of fashionable dressing. The clamor of these intellectuals about the widespread desire to be “current” reveals the significant space fashion inhabited in the empire – a space that was repeatedly gendered female. This dissertation considers fashion as a system of social practices that is governed by material relations – a system that is also embroiled in the politics of the gendered self and the body. I demonstrate that this notion of fashion is the best way to understand the process through which competition for status and self-identification among elites gradually broke away from the imperial court and its system of official ranks. -

It can be distinguished from all congeners by the fol- lowing combination of characteristics: no spots on operculum; gill rakers 15-20; lateral-line scales 98-116; pyloric caeca 60-71. Unique morphological characters and genetic divergence of this species are discussed. This species has a limited distribution in several streams of the middle part of the Qinling Mountains in China. Methods for management and pro- tection of B. tsinlingensis need to be re-evaluated. Key words: Brachymystax, revalidation, redescription, Salmonidae, China Introduction The genus Brachymystax Günther, 1866, belonging to Salmonidae, Salmoniformes, is distributed in eastern and northern Asia with three currently recognized valid species (Froese & Pauly, 2014): B. -

Megdal Received: 6 December 2016; Accepted: 13 March 2017; Published: 16 March 2017 Abstract: Human disturbances impact river basins by reducing the quality of, and services provided by, aquatic ecosystems. Conducting quantitative assessments of ecological security at the watershed scale is important for enhancing the water quality of river basins and promoting environmental management. In this study, China’s Songhua River Basin was divided into 204 assessment units by combining watershed and administrative boundaries. Ten human threat factors were identified based on their significant influence on the river ecosystem. A modified ecological threat index was used to synthetically evaluate the ecological security, where frequency was weighted by flow length from the grids to the main rivers, while severity was weighted by the potential hazard of the factors on variables of river ecosystem integrity. The results showed that individual factors related to urbanization, agricultural development and facility construction presented different spatial distribution characteristics. At the center of the plain area, the provincial capital cities posed the highest level of threat, as did the municipal districts of prefecture-level cities. -

Diversity and Risk Patterns of Freshwater Megafauna: a Global Perspective
Diversity and risk patterns of freshwater megafauna: A global perspective Inaugural-Dissertation to obtain the academic degree Doctor of Philosophy (Ph.D.) in River Science Submitted to the Department of Biology, Chemistry and Pharmacy of Freie Universität Berlin By FENGZHI HE 2019 This thesis work was conducted between October 2015 and April 2019, under the supervision of Dr. Sonja C. Jähnig (Leibniz-Institute of Freshwater Ecology and Inland Fisheries), Jun.-Prof. Dr. Christiane Zarfl (Eberhard Karls Universität Tübingen), Dr. Alex Henshaw (Queen Mary University of London) and Prof. Dr. Klement Tockner (Freie Universität Berlin and Leibniz-Institute of Freshwater Ecology and Inland Fisheries). The work was carried out at Leibniz-Institute of Freshwater Ecology and Inland Fisheries, Germany, Freie Universität Berlin, Germany and Queen Mary University of London, UK. 1st Reviewer: Dr. Sonja C. Jähnig 2nd Reviewer: Prof. Dr. Klement Tockner Date of defense: 27.06. 2019 The SMART Joint Doctorate Programme Research for this thesis was conducted with the support of the Erasmus Mundus Programme, within the framework of the Erasmus Mundus Joint Doctorate (EMJD) SMART (Science for MAnagement of Rivers and their Tidal systems). EMJDs aim to foster cooperation between higher education institutions and academic staff in Europe and third countries with a view to creating centres of excellence and providing a highly skilled 21st century workforce enabled to lead social, cultural and economic developments. All EMJDs involve mandatory mobility between the universities in the consortia and lead to the award of recognised joint, double or multiple degrees. The SMART programme represents a collaboration among the University of Trento, Queen Mary University of London and Freie Universität Berlin.
