The 2006 Zoological Science Editorial Board (Yoshitaka Nagahama, Editor-in-Chief) selected the candidate papers for the 2007 ZOOLOGICAL SCIENCE AWARD. Upon receiving this proposal, the Board of Directors and the Council deliberated and decided on the 2007 ZOOLOGICAL SCIENCE AWARD as follows.<\/p>\n\n\n\n
1) Section: Reproductive Biology
\nInduction of Female-to-male Sex Change in the Honeycomb Grouper (Epinephelus merra) by 11-ketotestosterone Treatments.
\nRamji K. Bhandari, Mohammad A. Alam, Kiyoshi Soyano and Masaru Nakamura
\nZoological Science 23 (1): 65-69 (2006)
\nGroupers undergo sex change from female to male. To elucidate the endocrine regulatory mechanism of this sex reversal, females were treated with 11-ketotestosterone, a natural androgen in fish. It was revealed that the ovaries of all treated individuals transformed into males with mature testes. We proved that the sperm of these males can fertilize mature eggs from normal females. Thus, this paper is of high value in clarifying that androgens play a crucial role in sex change. Furthermore, it contributes to applications in fish aquaculture.<\/p>\n\n\n\n
2) Section: Ecology
\nLong Tails Affect Swimming Performance and Habitat Choice in the Male Guppy.
\nKenji Karino, Kazuhiro Orita and Aya Sato
\nZoological Science 23 (3): 255-260 (2006)
\nThe striking colorful patterns and long caudal fins of male freshwater guppies have been studied as a model of sexual dimorphism evolved through sexual selection. However, the reproductive benefits and survival costs theoretically assumed in the field of evolutionary ecology are exceptionally difficult to reliably measure in practice. In this paper, the authors clearly demonstrate, for the first time through measured values under artificial and natural conditions, the interaction between the microhabitat and the cost associated with the long caudal fin, which had merely been believed to exist. It will likely be cited in textbooks for a long time to come.<\/p>\n\n\n\n
3) Section: Animal Diversity and Evolution
\nRound-trip Catadromous Migration in a Japanese Amphipod, Sternomoera rhyaca (Gammaridea: Eusiridae).
\nKeiko Kuribayashi, Haruo Katakura, Masaki Kyono, Matthew H. Dick and Shunsuke F. Mawatari
\nZoological Science 23 (9): 763-774 (2006)
\nThis paper offers an evolutionary perspective on an interesting amphipod behavior encountered during taxonomic work. While its methodology is not particularly novel, it is an exciting paper. Unlike so many formulaic papers\u2014taxonomy consisting of species description papers and phylogenetics consisting of DNA sequence comparisons, regardless of the target taxonomic group\u2014this paper fully captures the true thrill of discovery in field research, reminiscent of the \"natural history\" studies of the past, and is of high quality.<\/p>\n\n\n\n
4) Section: Developmental Biology
\nEarly Development of Zooxanthella-containing Eggs of the Corals Porites cylindrica and Montipora digitata: The Endodermal Localization of Zooxanthellae.
\nMamiko Hirose and Michio Hidaka
\nZoological Science 23 (10): 873-881 (2006)
\nTo understand the dynamics of zooxanthellae symbiosis in corals, specifically the mechanism of symbiosis initiation during ontogeny, the authors investigated in detail the distribution of zooxanthellae during the early development of two coral species, Porites cylindrica and Montipora digitata. The results showed that the distribution mechanism of zooxanthellae exhibits species-level differences associated with the type of gastrulation mechanism. This is an interesting paper of extremely high quality from the perspective of comparative zoology.<\/p>\n\n\n\n
5) Section: Animal Diversity and Evolution
\nTime Scale for Cyclostome Evolution Inferred with a Phylogenetic Diagnosis of Hagfish and Lamprey cDNA Sequences.
\nShigehiro Kuraku and Shigeru Kuratani
\nZoological Science 23 (12): 1053-1064 (2006)
\nThis paper provides an evolutionary discussion based on in silico analysis using cDNA sequence information from hagfish and lampreys regarding the timescale of cyclostome evolution. From this discussion, it draws the conclusion that the two groups diverged relatively quickly after the common ancestral lineage of cyclostomes split from the agnathan lineage. This research is highly praised for sharply tackling the major evolutionary question of cyclostomes, which is of great zoological significance, using a novel methodology.<\/p>","protected":false},"excerpt":{"rendered":"\u66f4\u65b0\u65e5\uff1a2009\u5e742\u670810\u65e5 \u5e73\u6210\uff11\uff18\u5e74\u5ea6Zoological Science \u7de8\u96c6\u59d4\u54e1\u4f1a\uff08\u9577\u6ff1\u5609\u5b5d\u59d4\u54e1\u9577\uff09\u306f\u3001\u5e73\u6210\uff11\uff19\u5e74\u5ea6\u3000ZOOLOGICAL SCIENCE AWARD\u3000\u5019\u88dc\u8ad6\u6587\u3092\u6c7a\u5b9a\u3057\u3001\u7406\u4e8b\u4f1a\u30fb\u8a55\u8b70\u54e1\u4f1a\u306f\u3001\u305d\u306e\u63d0 […]","protected":false},"author":5,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_post_was_ever_published":false},"categories":[14],"tags":[43],"class_list":["post-1707","post","type-post","status-publish","format-standard","hentry","category-other_award","tag-zoological-science-award"],"acf":[],"jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/pb55P2-rx","jetpack_featured_media_url":"","_links":{"self":[{"href":"https:\/\/www.zoology.or.jp\/english\/wp-json\/wp\/v2\/posts\/1707","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.zoology.or.jp\/english\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.zoology.or.jp\/english\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.zoology.or.jp\/english\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/www.zoology.or.jp\/english\/wp-json\/wp\/v2\/comments?post=1707"}],"version-history":[{"count":1,"href":"https:\/\/www.zoology.or.jp\/english\/wp-json\/wp\/v2\/posts\/1707\/revisions"}],"predecessor-version":[{"id":1712,"href":"https:\/\/www.zoology.or.jp\/english\/wp-json\/wp\/v2\/posts\/1707\/revisions\/1712"}],"wp:attachment":[{"href":"https:\/\/www.zoology.or.jp\/english\/wp-json\/wp\/v2\/media?parent=1707"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.zoology.or.jp\/english\/wp-json\/wp\/v2\/categories?post=1707"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.zoology.or.jp\/english\/wp-json\/wp\/v2\/tags?post=1707"}],"curies":[{"name":"WP","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
