On 22 July 2009, partial solar eclipse was observed in most regions in Japan and a total solar eclipse was observed in the Southwest Islands. At the Nara Campus of Kinki University, located in Nara Prefecture, central Japan, the sun fell into eclipse at 9:46, the maximum eclipse occurred at 11:05 (82% eclipse) and the eclipse finished at 12:25. The weather was cloudy and occasionally the sun peeped through the clouds.At the maximum eclipse, the following phenomena were observed:1) The ratio of singing individuals of two species of cicada, Platypleura kaempferi, and Graptopsaltria nigrofuscata, singing in daylight was reduced, hereas he higurashi cicada, Tanna japonensis, which sings at early morning and evening, began to sing actively.2) The katydids, Gampsocleis buergeri ,which sing in daylight, were silent.3) Two species of bird, Hypsipetes amaurotis and Cettia diphone were silent.4) The activities of flight butterfly species, Zizeeria maha, declined.5) The leaves of the silk tree, Albizia julibrrissin., which normally close at night, begun to close.6) The amount of solar radiation decreased and the air temperature declined.The response of some animals and plants to the eclipse may be coused by these weather factors which caused by solar eclipse.

2009年7月22日、日本各地で部分日食が観測され、南西諸島においては皆既日食が観測された。近畿大学奈良キャンパスの位置する奈良県では9時46分に日食が開始し、11時05分に太陽の82%が欠ける最大食に達した後、12時25分に終了した。当日の天気は曇りで、時々太陽が雲越しに見え隠れしていた。最大食時には、鳴き声を出す昆虫類ではニイニイゼミ、キリギリスが減少し、ヒグラシが増加した。鳥類ではヒヨドリの鳴き声、ウグイスのさえずりの聞こえる数が少なくなった。チョウは全体的に活動する種数、個体数が減少し、ネムノキの葉は就眠運動により閉じる傾向が見られた。気象観測データは日射量や気温が低下しており、生物の行動はこれらの影響を受けたものと考えられた。

The structure of wild bird communities in two areas of the Nara Campus of Kinki University was observed from June, 2008 to May, 2009. Pond A, Coppice, Farm and School Site A were the observation points in one area. The observation route in this area was named A-course. Pond E, East Ground, West Ground and School Site E were the observation points in the second area. The observation route in this area was named E-course.Among these environments, the greatest number of species was recorded at Pond A, where the wild bird fauna mostly consisted of waterfowl and rassland birds. The Index of species diversity H' at Coppice was the highest of this survey, where the wild bird fauna mostly consisted of forest birds. The number of species from the Red List of Endangered Animals at Farm was the second highest of this survey. The number of species at School Site A, where the wild bird fauna mostly consisted of common species, was the lowest among these environments. The total population of wild birds counted at Pond E, where the wild bird fauna mostly consisted of waterfowl and grassland birds, was the highest among these environments. The total population of Red List species found at East Ground, where the wild bird fauna mostly consisted of grassland birds, was the lowest among these environments.The Index of species diversity H' was the lowest at East Ground. The overlap indices Cπ at School Site E was the highest in combination with School Site A. The wild bird fauna at these sites mostly consisted of arboreal birds.
