  • Normal Development of an Aquatic Spawning Tree Frog, <i>Buergeria japonica</i> (Amphibia: Rhacophoridae)

    KUROSHIMA Shota, TOMINAGA Atsushi

    Current Herpetology ( Herpetological Society of Japan )  40 ( 2 ) 169 - 181   2021.08 [ Peer Review Accepted ]

    Type of publication: Research paper (scientific journal)

     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

    NAKAMURA Yasuyuki, TOMINAGA Atsushi

    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>
