Download Endemism Of Subterranean Diacyclops In Korea And Japan With Descriptions Of Seven New Species Of The Languidoides Group And Redescriptions Of D Brevifurcus Ishida 2006 And D Suoensis Ito 1954 Crustacea Copepoda Cyclopoida books, This work explores for the first time comprehensively the diversity and endemism of subterranean copepod crustaceans from the genus Diacyclops in the Far East. Previous scarce records have indicated presence of only a few widely distributed species, despite relative isolation of subterranean habitats in this part of the world and very dynamic changes in topography during the Pleistocene glacial cycles. A wide range of samples from Korea and Japan are studied, and all previous records of subterranean Diacyclops are re-evaluated. Morphological analyses of microcharacters, many of which are used in cyclopoid taxonomy for the first time herein, reveal high diversity in both countries. No subterranean species is found in common, although the existence of four sibling species pairs is probably indicative of relatively recent speciation. Seven species are described as new to science and two are re-described. This research provides evidence for the importance of subterranean habitats as reservoirs of biodiversity, and also demonstrates the inadequacy of current morphological methods for identifying closely related species of copepods. The disproportionately high diversity and short-range endemism discovered around Lake Biwa provides further evidence for the role of ancient lakes as biodiversity pumps for subterranean habitats.

Species Diversity Of Animals In Japan

by Masaharu Motokawa, Species Diversity Of Animals In Japan Books available in PDF, EPUB, Mobi Format. Download Species Diversity Of Animals In Japan books, This book summarizes the status quo of the knowledge about the biodiversity in terrestrial, freshwater, and marine animals that live in Japan. Consisting of some 6,800 islands that are arrayed for approximately 3,500 km from north to south, the Japanese archipelago has a complex history in a paleogeographic formation process over time and harbors rich flora and fauna. This work will contribute to establishing a general biogeographic theory in archipelagoes around continental shelves. Facing the ongoing extinction crisis, one of the most important tasks for our generation is to bequeath this precious natural heritage to future generations. As the first step toward this goal, a species list has been compiled through solid, steady alpha-taxonomic work in each taxon. Furthermore, the phylogeography and population genetic structure for each species is elucidated for deeper understanding of the local fauna, the scientific results of which should be the basis for establishing conservation policies and strategies. Also the problem of alien or introduced species is investigated as another threat to the native fauna.Each of the 27 chapters is written by the most active specialist leading the field, thus readers can acquire up-to-date knowledge of the animal species diversity and their formation process of Japanese animals in the most comprehensive form available. This book is recommended for researchers and students who are interested in species diversity, biogeography, and phylogeography.
