Recognition of the wide diversity of organisms that maintain complex haploid-diploid life cycles has generated interest in understanding the evolution and persistence of such life cycles. We empirically tested the model where complex haploid-diploid

Arrest at Metaphase of Meiosis I in Starfish Oocytes in the Ovary is Maintained by High CO2and Low O2Concentrations in Extracellular Fluid

Autor: Noritaka Hirohashi, Fumio Nakaya, Kazuyoshi Chiba, Kei Moriwaki, Takako Nakagawa

Publikováno v: Zoological Science. 30:975-984

During the spawning process in starfish, oocytes are arrested at metaphase of meiosis I (MI) within the ovary, and reinitiate meiosis only after they have been released into the seawater. However, this arrest does not occur if the ovary is removed fr

Sneaker Male Squid Produce Long-lived Spermatozoa by Modulating Their Energy Metabolism *

Autor: Noritaka Hirohashi, Miwa Tamura-Nakano, Tomohiro Iida, Fumio Nakaya, Yoko Iwata

Spermatozoa released by males should remain viable until fertilization. Hence, sperm longevity is governed by intrinsic and environmental factors in accordance with the male mating strategy. However, whether intraspecific variation of insemination mo

Should Candidates Smile to Win Elections? An Application of Automated Face Recognition Technology

Autor: Fumio Nakaya, Tadashi Komatsu, Yusaku Horiuchi

Publikováno v: Political Psychology. 33:925-933

The smile index has statistically significant and substantial effects on the vote share of candidates even after controlling for other covariates. Previous studies examining whether the faces of candidates affect election outcomes commonly measure st

Substantial energy expenditure for locomotion in ciliates verified by means of simultaneous measurement of oxygen consumption rate and swimming speed

Autor: Yumiko Katsu-Kimura, Shoji A. Baba, Fumio Nakaya, Yoshihiro Mogami

Publikováno v: Journal of Experimental Biology. 212:1819-1824

SUMMARY In order to characterize the energy expenditure of Paramecium, we simultaneously measured the oxygen consumption rate, using an optic fluorescence oxygen sensor, and the swimming speed, which was evaluated by the optical slice method. The sta

Oxygen consumption of a single embryo/planula in the reef-building coral Acropora intermedia

Autor: H. H. Yamamoto, Fumio Nakaya, Nami Okubo, K. Okaji

Publikováno v: Marine Ecology Progress Series. 366:305-309

O2 consumption of a single embryo/planula at each developmental stage was monitored in the reef-building coral Acropora intermedia using an optical O2-sensing system with our original micro-chamber system (6.28 µl). The lowest rate of O2 consumption
