Printedonacid-freepaper ThisSpringerimprintispublishedbySpringerNature TheregisteredcompanyisSpringerJapanKK Preface Consistingofsome6800islandsandextendingapproximately3500kmfromnorth (45.6(cid:1)N)tosouth(20.4(cid:1)N),theJapanesearchipelagoalongtheeasternperipheryof the Eurasian continent has had a complex geological history since the Miocene (ca.23millionyearsago),withavarietyofterrestrialandmarinehabitatsharboring a rich flora and fauna (Chap. 1). The Japanese fauna has a high proportion of endemicspecies,e.g.,52%fornon-flyingterrestrialmammals(Chap.3),47%for land birds (Chap. 4), 83% for reptiles (Chap. 5), and 92% for amphibians (Chap. 6). Regrettably, anthropogenically mediated habitat loss and disturbance have resulted in the extinction of a number of endemic Japanese species, subspe- cies, or populations, e.g., the Japanese wolf (Canis lupus), the Japanese sea lion (Zalophus japonicus), the Japanese crested ibis (Nipponia nippon), and the Japa- nese river otter (Lutra lutra). More than half the natural mudflats along Japanese coasts have been reclaimed, mostly for agriculture or industry, causing local extinctions—many of which have perhaps gone undetected—of small marine or estuarine organisms such aspolychaetes (Chap. 19).Itis important forourgener- ationtobequeathourpreciousnaturalheritagetofuturegenerations,andtherefore itisvitalthatscientistsengagedinbiodiversityresearchdisseminatetheknowledge theyobtaintothegeneralpublic,notonlydomesticallybutalsoglobally.Thefirst step toward this goal is to compile a species list through solid, steady alpha- taxonomicworkineachtaxon(Chaps.6,9,10,11,12,13,14,15,16,17,18,19, 20,21,22,23,24,25,26,and27).Furthermore,foradeeperunderstandingofthe Japanesefauna,itiscrucialtoelucidatethephylogeographyandpopulationgenetic structureofeachspecies(Chaps.3,5,and6),andtheseresultsshouldformthebasis forconservationpoliciesandstrategies(Chaps.6,19,and27).Anotherthreattothe nativefaunaistheproblemofalienorintroducedspecies(Chaps.6and22). In2013,Okinawainfar-southernJapanwasselectedasthevenueforthe22nd InternationalConferenceofZoology(ICZ)in2016,tobeheldjointlywiththe87th Meeting of Zoological Society of Japan (ZSJ, founded in 1878). The Library/ Publishing Committee of ZSJ, at the time under the chairmanship of Professor Kazufumi Takamune (Kumamoto University), then initiated a project aimed to facilitate the global dissemination of information on the activities of Japanese v vi Preface zoologistsandthecurrentstatusofzoologyinJapan,tocommemoratetheoccasion oftheICZ–ZSJjointmeetings.Thisprojectwouldentailthepublicationofaseries ofbooksunderthetitleDiversityandCommonalityinAnimals,featuringresearch conducted by members of ZSJ in various fields of zoology, including physiology, endocrinology, neuroscience, ethology, developmental biology, evolution, repro- ductive biology, taxonomy, and ecology. MM (mammalian systematics) and HK (marine invertebrate systematics), representing the Kinki and Hokkaido Branches of ZSJ, respectively, were Library/Publishing Committee members in the early planning stages ofthepublicationproject andweresubsequently appointedasthe editorsofavolumepertainingtobiodiversity,whichemergedasthisbook,Species DiversityofAnimalsinJapan. Thereare23nationwideacademicsocietiesinJapanwithmembersengagedin animal diversity research to various extents (approximate membership shown in parentheses): Arachnological Society of Japan (300), Carcinological Society of Japan (300), Coleopterological Society of Japan (700), Japanese Association of Benthology(400),JapanSocietyofProtistology(200),TheAcarologicalSocietyof Japan(250),TheBiogeographicalSocietyofJapan(300),TheEcologicalSociety of Japan (3800), The Entomological Society of Japan (1400), The Herpetological SocietyofJapan(400),TheIchthyologicalSocietyofJapan(1300),TheJapanese CoralReefSociety(600),TheJapaneseNematologicalSociety(240),TheJapanese SocietyofSoilZoology(310),TheJapaneseSocietyofSystematicZoology(400), The Lepidopterological Society of Japan (1400), The Malacological Society of Japan(800),TheMammalSocietyofJapan(1100),TheOrnithologicalSocietyof Japan(1200),ThePlanktonSocietyofJapan(600),ThePalaeontologicalSocietyof Japan(1100),TheSocietyofEvolutionaryStudies,Japan(1300),andTheZoolog- icalSocietyofJapan(2300). ZSJ has fewer specialist members (i.e., acarologists, arachnologists, crustacean researchers, ecologists, entomologists, herpetologists, ichthyologists, malacologists, mammalologists,nematologists,andpaleontologists)thananyofthecorresponding specializedsocieties—inotherwords,Japaneseresearchersparticipatinginbiodiver- sity research do not have a single platform. To help overcome this organizational deficiency,TheUnionofJapaneseSocietiesforNaturalHistorywasfoundedin1995, andTheUnionoftheJapaneseSocietiesforSystematicBiologyin2002,tocoordi- natetheactivitiesofthoseacademicsocietiesengagedinresearchinnaturalhistory and systematics. This coordination includes capacity-building for natural history museumsandspecimenstorage,improvementofglobalspecies-diversityinformation facilities,andtheenhancementofyoungresearchers.Asaconsequence,networksof researchersandtheknowledgeofanimalspeciesdiversityinJapanhavebeengreatly enhancedinthelasttwodecades. The intent of this book is to summarize and provide the status quo of our knowledge of the biodiversity of the major groups of terrestrial, freshwater, and marineanimalsinJapan.Eachchapteriswrittenbyaleadingcurrentspecialistin thefield.Inwell-studiedgroupssuchasvertebrates,thetopicsaretreatedinterms of the process of the formation of the faunas in geological time, i.e., during the Quaternary period (Chaps. 1, 3, and 5), as well as the biogeographic patterns of Preface vii community composition (Chap. 4). On the other hand, a number of taxa remain poorlyinvestigated, mostlyamongmarineinvertebrates(Chaps.2,13,14,15,16, 17,18,19,20,21,22,23,24,25,26,and27)butalsointerrestrialandfreshwater groups(Chaps.8,9,10,11,and12). The authors of each chapter in this book are members of ZSJ and/or active contributors to the society’s periodical journals,ZoologicalScience and Zoological Letters. They range in stage of career from young postdocs (Chaps. 9 and 20) to professorsemeritus(Chaps.17,26,and27),andwerechosenasspecialistsinmajor groups of animals. The following phyla are not covered in this book: Placozoa, Ctenophora, Platyhelminthes, Orthonectida, Gnathostomulida, Gastrotricha, Rotifera, Phoronida, Brachiopoda, Chaetognatha, Cycliophora, Micrognathozoa, Mollusca,Nematomorpha,Priapulida,Loricifera,Onychophora,Xenacoelomorpha, and Hemichordata. Completeness in taxonomic coverage at the phylum level was hamperedlargelyduetotheabsenceorpaucityofexpertsinZSJ(e.g.,Mollusca)or oftheanimalsthemselvesinJapan(e.g.,Cycliophora,Micrognathozoa,Onychophora). Futurestudiesandcollaborationsareexpectedtofillthegap,andwehopethatthisbook willstimulatefutureresearch.
