Available in PDF, EPUB and Kindle. Book excerpt: Chironomid midges breeding in Lake Biwa were collected by the authors and their collaborators during the period from April 1985 to June 1986 mainly using three different methods; 1) The collection of adults resting or swarming on the lake shore with nets or sucking tubes. 2) The collection of larvae together with bottom sediments and water weeds and their rearing in the laboratory to obtain emerging male adults with which the identification of species was made. 3) The collection of adults with a light trap operated once a week on the shore of the lake. As a result, a total of 71 chironomid species were collected and identified in and around the lake. Of the collected species, 47 belonged to the subfamily Chironominae, 18 to Orthocladinae, 1 to Diamesinae, and 5 to Tanypodinea. The collection included 6 new species and 5 species new to Japan, and morphological and taxonomical accounts have been presented for these species. The seasonal trends of the emergence of two giant midges, Chironomus plumosus and Tokunagayusurika akamusi, from the lake were observed by means of the light trap samples. Ch. plumosus, a cosmopolitan lake midge, seemd [i.e. seemed] to appear three time a year, in early April, June and September, while T. akamusi, a species indigenous to East Asia, appeared only once in November. The collection contained a number of taxonomically interesting species. For example, Biwatendipes motoharui Tokunaga (1965) was collected in large numbers in April resting on the lake shore, and proved to have very noteworthy morphological characters more or less intermediate between the tribes Chironomini and Tanytarsini of the subfamily Chironominae. All the six new species described in this paper, Camptochironomus biwaprimus, Paratanytarsus biwatertius, Tanytarsus kirai, T. biwatrifurcatus, Cricotopus biwannulatus, and Eukiefferiella biwaquarta, showed morphological characteristics not found in previously recorded chironomid species.

Available in PDF, EPUB and Kindle. Book excerpt: Although, the first edition had a similar focus, more than five years have passed since its publication and the biological and social circumstances of the lake have drastically changed due to, for example, the further expansion of alien species, the decrease of indigenous species, the progress of integrated watershed management by the Union of the Kansai Government which was established in 2010, the legislation of the Conservation and Restoration Act of Lake Biwa in 2015 and more. The new edition will therefore feature updated and new information on the above and more topics as well as updated and revised data based on the latest research. Inventories of respective taxa, especially those of small animals, are also revised based on the latest studies. Furthermore, this volume covers the characteristics of the biota of this ancient lake, but at the same time, it will also approach it as a ‘culture ancient lake’. Other topics also include water pollution, lakeshore development, the effects of global warming in the past and present, the influence of people, and countermeasures by local and national governments. Moreover, the volume also provides a comprehensive view on the future of Lake Biwa and that of its residents. Miraculously enough, this ancient lake has kept its water quality clear even until today despite the fact of more than 1.4 million people living on its shores. Finally, the book also gives indispensable information to those engaged in improving and conserving water regimes of lakes and other water bodies all over the world and to those interested in the culture and history of Japan. Lake Biwa is not only one of the rarest ancient lakes of the world, but the people’s involvement with the lake also goes back a long way. This is shown in the diverse culture developed in this area and in the various archaeological finds that date back as early as the Jomon Period, nearly 10.000 years ago. Today Lake Biwa fulfills an important role as a water resource by providing domestic, commercial, industrial, and agricultural water for over 14 million residents living around the Lake Biwa-Yodo River drainage basin. This updated volume focuses on the geological and biological features of the lake as well as on the long-term interactions between the people and the lake.
Download or read book Chironomidae Diptera of Japan written by Manabu Sasa and published by . This book was released on 1995 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: The non-biting chironomid midges (Family Chironomidae, Order Diptera) include numbers of species whose larvae develop in bodies of fresh water and which play an important role in the transmission of nutrients along the food chain. They consume organic matter and microorganisms from the bottoms of these bodies of water, and then are themselves eaten by fishes and arthropods. They do not usually cause damage or transmit diseases, and as a result have been neglected by entomological research. But their usefulness in indicating levels of pollution and water quality conditions makes them important objects of study.

Available in PDF, EPUB and Kindle. Book excerpt: The dipteran family Chironomidae is the most widely distributed and frequently the most abundant group of insects in freshwater, with rep resentatives in both terrestrial and marine environments. A very wide range of gradients of temperature, pH, oxygen concentration, salinity, current velocity, depth, productivity, altitude and latitude have been exploited, by at least some chironomid species, and in grossly polluted environments chironomids may be the only insects present. The ability to exist in such a wide range of conditions has been achieved largely by behavioural and physiological adaptations with relatively slight morphological changes. It has been estimated that the number of species world-wide may be as high as 15000. This high species diversity has been attributed to the antiquity of the family, relatively low vagility leading to isolation, and evolutionary plasticity. In many aquatic ecosystems the number of chironomid species present may account for at least 50% of the total macroinvertebrate species recorded. This species richness, wide distribution and tolerance to adverse conditions has meant that the group is frequently recorded in ecological studies but taxonomic difficulties have in the past prevented non-specialist identification beyond family or subfamily level. Recent works, including genetic studies, have meant that the family is receiving much more attention globally.

But their usefulness in indicating levels of pollution and water quality conditions makes them important objects of study. This volume is a comprehensive summary of available information and research on the chironomid midges of Japan and East Asia: their taxonomy, biology, distribution, ecology, and relation to human life. It includes nearly 100 plates with copious detailed illustrations of the major genera and of the hypopygeal structures on which species identification is based. The extensive Key provides a guide to identifying all of the known chironomid species from Japan on the basis of the male genitalia. The authors, noted entomologists and experts on the Chironomidae, have compiled more than a century of research on these important insects into a single-volume reference work that will be useful not only to entomologists but also to environmental and public-health scientists.

This book was released on 2016-09-12 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Chironomidae, or Midges, of Illinois, With Particular Reference to the Species Occurring in the Illinois River The members of this family are among the commonest and most widely distributed Of the two-winged ies, occurring on every conti nent and in all the fauna] areas into which these continents have been divided. Although considerably over one thousand species have been described, it is certain that this is but a small fraction of the total num ber of species which must occur throughout the world. The reasons for this paucity of described species are obvious. The fragile strue ture of most of the species prevents their being readily preserved, and their frequent close similarity deters all but a few specialists from working on the family. Despite the extremely fragile structure of the members Of this family many fossil species have been described by various authors. Conjectures as to the possible sources from which the family sprang must remain, as in the case of other families, mere conjectures, serving only to create purely academic discussion, which has no proper place in the present paper. It may, however, be useful to students Of the Diptera to indicate, as clearly as possible from the available data, the characteristics of the family.
