　View Summary

<p>The family Rhacophoridae, including <i>Buergeria japonica</i>, shows a great diversity of reproductive patterns, but the knowledge of developmental processes is still limited. The genus <i>Buergeria</i> is a sister group to all other rhacophorids and shows a conservative, probably primitive, reproductive mode for this family. Thus, it is valuable to clarify the developmental process in this genus for understanding the evolution and diversification history of reproductive modes and developmental processes across the broader family members. In this study, we describe the normal development of <i>B. japonica</i> by rearing eggs and larvae under ambient temperatures of 27±1°C. The developmental speed of <i>B. japonica</i> from fertilization to gill elongation (stage 20), corresponding to their hatching period, was faster than most of other anuran species, when comparison was made using relative age, which is independent of temperature. The rapid embryonic development may be advantageous in their highly fluctuating breeding environment.</p>

Diet of the American Bullfrog <i>Lithobates catesbeianus</i> Naturalized on Okinawajima, Ryukyu Archipelago, Japan

Current Herpetology ( Herpetological Society of Japan )  40 ( 1 ) 40 - 53   2021.02 [ Peer Review Accepted ]

Type of publication: Research paper (scientific journal)

　View Summary

<p>The diet of the nonnative American Bullfrog <i>Lithobates catesbeianus</i> occurring in Ogimi Village of Okinawajima, Ryukyu Archipelago, is investigated. Seventy two of 89 frogs (nine adults, five subadults, and 58 juveniles) captured had food items in its stomach. We identified a total of 64 taxa from 253 food items. Our analyses show that (1) the diet consists mainly of terrestrial prey, (2) mollusks and vertebrates are the essential prey groups for adults and subadults, and (3) odonates, mollusks, and arachnids are the main prey for juveniles. Such dietary habits are quite different from those of several conspecific nonnative populations in mainland Japan and other regions. Part of this is most likely related to the absence of the frog's favorite prey, nonnative American crayfish <i>Procambarus clarkii</i>, in the study area. We also confirm the predation of a poisonous newt <i>Cynops ensicauda popei</i> (Salamandridae) and several aquatic insects by this frog and present some implications for these results.</p>

Type of publication: Research paper (scientific journal)

　View Summary

<p>The abundant clouded salamander from western Japan, <i>Hynobius nebulosus</i>, has long been considered a single widespread species, although some authors have suggested the inclusion of several cryptic species. This led to a molecular and morphological analysis of populations from all parts of the known range. Phylogenetic relationships were inferred from complete sequences of the mitochondrial cytochrome b gene, and nuclear genome differentiations were estimated by multiplexed inter simple sequence repeat genotyping by sequencing (MIG-seq). The results suggest that <i>H. nebulosus</i> hitherto recognized consists of at least nine species. We applied existing names to two of them, <i>H. nebulosus</i> (Temminck et Schlegel) and <i>H. vandenburghi</i> Dunn, and described seven others as new species.</p>

　View Summary

<p>The Japanese giant salamander, <i>Andrias japonicus</i>, is known to exhibit very low genetic diversity, but the number of individuals surveyed in a population is limited by now. We investigated partial sequences (673 bp) of mitochondrial cytochrome b gene in 180 specimens of a population from the Inuyama Head Works on the Kiso River, Central Japan, over nine years so as to clarify the degree of genetic diversity. The result again confirmed a tendency of lack of diversity; only one individual differed from the remaining 179 with an uncorrected p-distance of only 1.5%. The individual had the sequence identical with that reported for an individual from San'in District of Western Japan, far from the Kiso River, and is thought to have been introduced artificially. The healthy condition of the salamander population in spite of highly reduced genetic diversities might be due to possible decrease of inbreeding depression, resulting from the past purging effect of ancestral inbreeding wherein deleterious recessive alleles were eliminated from the gene pool.</p>
