Nansei Islands Biological Diversity Evaluation Project Report 1 Chapter 1
Introduction WWF Japan’s involvement with the Nansei Islands can be traced back to a request in 1982 by Prince Phillip, Duke of Edinburgh. The “World Conservation Strategy”, which was drafted at the time through a collaborative effort by the WWF’s network, the International Union for Conservation of Nature (IUCN), and the United Nations Environment Programme (UNEP), posed the notion that the problems affecting environments were problems that had global implications. Furthermore, the findings presented offered information on precious environments extant throughout the globe and where they were distributed, thereby providing an impetus for people to think about issues relevant to humankind’s harmonious existence with the rest of nature. One of the precious natural environments for Japan given in the “World Conservation Strategy” was the Nansei Islands. The Duke of Edinburgh, who was the President of the WWF at the time (now President Emeritus), naturally sought to promote acts of conservation by those who could see them through most effectively, i.e. pertinent conservation parties in the area, a mandate which naturally fell on the shoulders of WWF Japan with regard to nature conservation activities concerning the Nansei Islands. This marked the beginning of the Nansei Islands initiative of WWF Japan, and ever since, WWF Japan has not only consistently performed globally-relevant environmental studies of particular areas within the Nansei Islands during the 1980’s and 1990’s, but has put pressure on the national and local governments to use the findings of those studies in public policy. Unfortunately, like many other places throughout the world, the deterioration of the natural environments in the Nansei Islands has yet to stop. -
Auditory Sexual Difference in the Large Odorous Frog Odorrana Graminea
J Comp Physiol A (2014) 200:311–316 DOI 10.1007/s00359-014-0885-3 ORIGINAL PAPER Auditory sexual difference in the large odorous frog Odorrana graminea Wei-Rong Liu · Jun-Xian Shen · Yu-Jiao Zhang · Zhi-Min Xu · Zhi Qi · Mao-Qiang Xue Received: 8 August 2013 / Revised: 15 January 2014 / Accepted: 22 January 2014 / Published online: 9 February 2014 © Springer-Verlag Berlin Heidelberg 2014 Abstract Acoustic communication is an important Abbreviations behavior in frog courtship. Male and female frogs of most AENFP Auditory evoked near-field potential species, except the concave-eared torrent frog Odorrana BEF Best excitatory frequency tormota, have largely similar audiograms. The large odorous CF Characteristic frequency frogs (Odorrana graminea) are sympatric with O. tormota, RMS Root mean square but have no ear canals. The difference in hearing between SPL Sound pressure level two sexes of the frog is unknown. We recorded auditory TS Torus semicircularis evoked near-field potentials and single-unit responses from the auditory midbrain (the torus semicircularis) to deter- mine auditory frequency sensitivity and threshold. The Introduction results show that males have the upper frequency limit at 24 kHz and females have the upper limit at 16 kHz. The Acoustic communication is often associated with the more sensitive frequency range is 3–15 kHz for males and behaviors of frogs, including territorial behavior, mate 1–8 kHz for females. Males have the minimum threshold at finding, courtship and aggression (Zelick et al. 1999). Dur- 11 kHz (58 dB SPL), higher about 5 dB than that at 3 kHz ing the breeding season, an adult male usually produces for females. -

E-mail: [email protected] (YYW); liuy353@ mail.sysu.edu.cn (YL) Abstract The genus Odorrana currently contains at least 56 recognized species that inhabits montane streams in subtropical and tropical Asia. Twenty new species have been described in the last decade, indicating the potential cryptic species diversity of this genus. We collected several specimens of Odorrana species from Southern China from 2007 to 2014, and on the basis of a combined morphological characters and phylogenetic analysis, we described the new species Odorrana feng- kaiensis sp. nov. herein. The new species is very similar to O. hainanensis and O. bacboensis, but can be consistently sep- arated by morphology, and allopatric distribution. It is further reciprocally monophyletic to O. -
Cryptic Species of a Cascade Frog from Southeast Asia: Taxonomic Revisions and Descriptions of Six New Species
PUBLISHED BY THE AMERICAN MUSEUM OF NATURAL HISTORY CENTRAL PARK WEST AT 79TH STREET, NEW YORK, NY 10024 Number 3417, 60 pp., 14 ®gures, 15 tables October 29, 2003 Cryptic Species of a Cascade Frog from Southeast Asia: Taxonomic Revisions and Descriptions of Six New Species RAOUL H. BAIN,1 AMY LATHROP,2 ROBERT W. MURPHY,3 NIKOLAI L. ORLOV,4 AND HO THU CUC5 ABSTRACT The Southeast Asian cascade frog, Rana livida (Blyth, 1856), has long been suspected to be a complex of species. Several different forms are described from across its vast range. The loss of type material and disparate sampling efforts are challenges. Is variability in this species due to geographic variation or to the presence of multiple species? We use concordant evidence from morphology, morphometrics, cellular DNA content, and allozyme electrophoresis to in- vestigate diversity in R. livida from Vietnam. Three distinct species are recognized on the basis of morphology, as are four other suspect groups (morphotypes). Discriminant function analyses of morphometric data detect patterns of morphological variation among all seven groups. Pairwise comparison of cellular DNA content using t-tests shows signi®cant differ- ences among sympatric morphotypes, suggesting they represent distinct species. This hypoth- esis is supported by an analysis of 14 allozymic loci, in which ®xed allelic differences are found among specimens in sympatry and allopatry. Examination of available type material of four junior synonyms of R. livida results in their recognition as species.

Embryonic Development of Concave-Eared Torrent Frog (Amolops Tormotus)
动 物 学 研 究 2010,Oct. 31(5):490−498 CN 53-1040/Q ISSN 0254-5853 Zoological Research DOI:10.3724/SP.J.1141.2010.05490 Embryonic development of the concave-eared torrent frog with its significance on taxonomy XIONG Rong-Chuan1,2, JIANG Jian-Ping1,* , FEI Liang1, WANG Bin1,2, YE Chang-Yuan1 (1. Chengdu Institute of Biology, the Chinese Academy of Sciences, Chengdu 610041, China; 2. Graduate University of the Chinese Academy of Sciences, Beijing 100049, China) Abstract: We investigated the early embryonic and larval development of the concave-eared torrent frogs, Odorrana tormota (Amphibia, Anura, Ranidae). Embryos were derived from artificial fertilization of frogs’ eggs, and the staging of development was based on morphological and physiological characteristics. Two major periods of development were designated: i) early embryonic period, from fertilization to operculum completion stage, lasted for 324 h at water temperature (WT) 18 −23℃; ii) larval period, from operculum completion stage to tail absorbed stage, took 1207 h at WT 20 − 24℃. Tadpoles of the concave-eared torrent frogs showed no evidence of abdominal sucker. Absence of this key characteristic supports the view from molecular systematics that concave-eared torrent frog does not belong to the genus Amolops. Two cleavage patterns were observed in embryos at 8-cell and 16-cell stages, with Pattern I - 2 (latitudinal cleavage at the 8-cell stage, and meridional cleavage at the 16-cell stage with two perpendicular meridional furrows) being the predominant pattern and only 1.5% belonging to Pattern II (meridional cleavage at the 8-cell stage and latitudinal cleavage at the 16-cell stage). -
Late Pleistocene-Holocene Amphibians
Palaeontologia Electronica palaeo-electronica.org Late Pleistocene-Holocene amphibians from Okinawajima Island in the Ryukyu Archipelago, Japan: Reconfirmed faunal endemicity and the Holocene range collapse of forest-dwelling species Yasuyuki Nakamura and Hidetoshi Ota ABSTRACT Amphibian fossils excavated from two Late Pleistocene-Holocene fissures in the southern part of Okinawajima Island in the Ryukyu Archipelago were identified through detailed comparisons with skeletal specimens of extant taxa. The identified species (eight frogs and two newts) were confined to extant elements on the island and were mostly endemic to either the island or the central part of the archipelago including it. Previous Late Pleistocene records of extralimital frogs (two mainland Japanese spe- cies [Glandirana rugosa and Rana tagoi] and one Southeast Asian frog currently natu- ralized in the Ryukyus [Polypedates leucomystax]) from one of the study sites (the Minatogawa Fissure) are therefore considered misidentifications. This may also be the case with Fejervarya kawamurai, a synanthropic frog currently widely distributed in East Asia, including the Central Ryukyus. Of the species obtained from the Late Pleis- tocene deposits at these sites, five frogs (Limnonectes namiyei, Babina holsti, Odor- rana ishikawae, O. narina, and Rana ulma) are forest-dwellers currently confined to the northern forested area of Okinawajima. Additionally, none of these species were detected in the middle Holocene deposits from one of the sites, the Sashiki Fissure. Our findings indicate that the southern limestone area of Okinawajima in the Late Pleistocene harbored a dense and humid forest with diverse lotic habitats, similar to the northern forested area of the island at present, and that these environmental condi- tions were lost by the midpoint of the Holocene Period.
