The function of allogeneic recognition in a marine sponge, Halichondria japonica, was examined by use of cut pieces contact assay. Individuals of this species were able to distinguish an allogeneic individual from an autogeneic one, and sho...
Refugia in glacial ages led to the current discontinuous distribution patterns of the dark red-backed vole Myodes rex on Hokkaido, Japan [0.03%]
第四冰川时期避难所导致日本北海道蒙弗尔氏红背田鼠(Myodes rex)当前不连续分布模式形成
Kuniko Kawai,Frank Hailer,Anna Pauline de Guia et al.
Kuniko Kawai et al.
The terrestrial mammalian fauna of the North Japanese island, Hokkaido, is more similar to that of Southern Siberia than to the main island of Japan, Honshu. Three species of the genus Myodes (Muridae, Rodentia) are found on Hokkaido, but n...
Geographic genetic structure in two laticaudine sea kraits, Laticauda laticaudata and Laticauda semifasciata (Serpentes: Elapidae), in the Ryukyu-Taiwan region as inferred from mitochondrial cytochrome b sequences [0.03%]

Nontivich Tandavanitj et al.
The Ryukyu-Taiwan region is an island arch with intervening waters of varying distances and depths. This study examines the geographic genetic structure of two sympatric sea kraits, Laticauda laticaudata and L. semifasciata, in the region, ...
Species boundaries of Astreopora corals (Scleractinia, Acroporidae) inferred by mitochondrial and nuclear molecular markers [0.03%]
基于线粒体和核分子标记的Astreopora属石珊瑚物种界限的划分
Go Suzuki,Keiichi Nomura
Go Suzuki
The genus Astreopora is a small but ancestral group in Acroporidae, which is one of the most diverse and dominant families of scleractinian coral in Indo-Pacific reefs. We estimated the species boundaries of Astreopora corals using two mole...
Identification of the precise kairomone-sensitive period and histological characterization of necktooth formation in predator-induced polyphenism in Daphnia pulex [0.03%]
水生枝角类节肢动物Daphnia pulex捕食者诱导产生的两型性中kairomone感知精确时期和颈部齿形成组织学特征的鉴定研究

Yuka Naraki
Many organisms have the ability to alter their development in the presence of predators, leading to predator-induced defenses that reduce vulnerability to predation. In the water flea Daphnia pulex, small protuberances called 'neckteeth' fo...
Relation between morphological antisymmetry and behavioral laterality in a poeciliid fish [0.03%]
一种丽鱼的形态不对称和行为侧偏之间的关系

Shoko Matsui
Many animals show lateral bias in various behaviors. In fish, behavioral laterality has been studied from the perspective of its relation with brain lateralization. On the other hands, in some fishes, head dimorphism (righty or lefty) corre...
Olfactory homing of chum salmon to stable compositions of amino acids in natal stream water [0.03%]
嗅觉导向归乡狗鱼以溯河返回故乡溪水中的稳定氨基酸组合为指引

Yuzo Yamamoto
Many attempts have been made to identify natal stream odors for salmon olfactory homing. It has recently been hypothesized that odors are dissolved free amino acids; however, it is unknown whether these odors change on a seasonal or annual ...
Release of relaxin-like gonad-stimulating substance from starfish radial nerves by lonomycin [0.03%]
海星辐神经中lonomycin诱发的类似松弛素促性腺物质的释放
Masatoshi Mita
Masatoshi Mita
In starfish, the peptide hormone gonad-stimulating substance (GSS) secreted from nervous tissue stimulates oocyte maturation to induce 1-methyladenine (1-MeAde) production by ovarian follicle cells. Recently, GSS was purified from radial ne...
