概要: The Ryukyu Flying Fox, Pteropus dasymallus, with anomalous body color was observed multiple times in July 2021, August 2 021 and August 2022 on Hateruma Island. Due to agreement of the external characteristics and the close sighted locations, these observations could be based on the same individual. White or light brown hair on the body and dark brown eyes suggest that anomalous body color was caused by hypomelanism. This report deals with a rare case of body color aberrations in fruit bats that roost on trees.
波照間島においてHypomelanismと考えられる体色異常のあるオスのヤエヤマオオコウモリPteropus dasymallus yayeyamaeを観察した. 2021年7月, 2021年8月, 2022年8月にほぼ同一地点で各一個体が目撃され, 個体の特徴も類似していたため, これらは同一個体と考えられた. 白色または淡褐色の体と濃褐色の眼を有していたことからhypomelanismと考えられる.本報告は樹上にねぐらを設けるオオコウモリの仲間では稀な体色異常の報告である.

概要: An alien Pachyrhynchini weevil, Metapocyrtus (Trachycyrtus) adspersus (Waterhouse, 1843), is newly recorded from Ishigak ijima Island, the Yaeyama Islands, Ryukyus, Japan. On Ishigakijima Island, the adults were found on shrubbery at an airport and a resort. There are concerns that this weevil will expand its distribution range on Ishigakijima Island, cause damage to cultivated plants, and subsequently disperse from Ishigakijima to other islands in the Yaeyama Islands.
石垣島未記録であったカタゾウムシ族のビサヤアカアシカタゾウムシを同島から初めて報告した. 本種はフィリピン原産, 広食性の外来種で, 国内ではこれまでに沖縄諸島 (沖縄島, 屋我地島, 瀬長島) および宮古諸島 (池間島) における発生が確認されており, 沖縄島では2018年以降の急速な分布拡大と果樹の食害が報告されている. 今回, 新たに石垣島内の空港とリゾート施設の敷地内の植栽上でそれぞれ発見されたことから, 今後同島における分布拡大, 植栽・果樹等における被害発生, そして石垣島から周辺離島への二次的分散が懸念される.

概要: We report here on a large Heliopora reef at depths of 2 to 10 m off the east coast of Okinawajima Island, Japan. The ree f was approximately 4610 m2 in area, and was made of up “Heliopora sp. group sp. 2” sensu Taninaka et al. (2021). This reef is almost twice as large as a previously reported Heliopora reef in Oura Bay, also on the east coast of Okinawajima I., but of a different lineage. The discovery and presence of these large Heliopora reefs on the east coast of Okinawajima I. demonstrate both the diversity of the genus and how underwater surveys are still needed for this coastline. Future research on the east coast of Okinawajima I. may yet find further unreported Heliopora assemblages. 続きを見る

概要: Background and Objectives: This article reports a method and the effectiveness of early childhood bilingual education in Japan implemented by a Japanese couple. In order to clarify the process of language acquisition of the target child, characteristics of her language development were analyzed in comparison with that of bilingual children in the literature. Research Design and Methods: A daughter raised by a Japanese couple in a Japanese context with the father speaking English to her was examined based on the records and observation by the father with an intention to determine the process of bilingual language acquisition (i.e., Japanese and English) in her early childhood. This practice was based on the “one parent; one language” principle in bilingual education. Additional analyses involved the comparison between the target child and another child of the same age raised by a couple with one native English speaker and one native Japanese speaker as well as another child raised by a Japanese couple whose English proficiency was at the beginning level. Results: (1) Even for the Japanese couple, with the “one parent; one language” principle, the target child’s language acquisition process showed nearly the same development compared to Japanese-English bilingual children in the literature.(2) The level of English attained by the target child was almost equivalent to that of the Japanese- English bilingual child raised by a couple with one native English speaker and one native Japanese speaker, with the level of Japanese equivalent to a Japanese native speaker of her age. Particularly for reading comprehension, reaching a high level of reading does not happen just because parents are native speakers of English / Japanese, but it depends greatly on their teaching methods and how they relate to their children when reading books to them. Parents should become facilitators and give children scaffolding for them to become autonomous readers. Discussion and Implications: Bilingual language development and proficiency in preschool children are expected to vary among individuals, so further research is needed to completely assure the early childhood bilingual language development of Japanese children. 続きを見る

概要: Two field trials were conducted in Northern Thailand from 2018 to 2020 to determine the best manual harvesting method fo r maximizing seed yield and seed quality of two Urochloa ruziziensis cultivars, cv. OKI-1 and cv. Br-203. Four manual seed harvesting methods were implicated in a randomized complete block design with four replicates. The four methods were as follows: knocking seeds from seedheads into a nylon net receptacle and collecting them once every day (T1); knocking seeds from seedheads into a nylon net receptacle and collecting them once every three days (T2); allowing ripe seeds to fall into a nylon net sheet that was stretched as a receptacle beneath the seedheads and collecting seeds once every five days (T3); and covering the tied seedheads with a nylon net bag and collecting seeds once every five days (T4). The highest pure seed yield was obtained from T3 in cv. Br-203 (333.11 kg/ha), as well as the highest trend in cv. OKI-1 (534.67 kg/ha). T3 produced 22–46% and 11–27% more pure germinated seed yields than the other methods in cv. Br-203 and cv. OKI-1, respectively. As a result, T3 was recommended for higher seed yield, convenient seed harvest, and reduced manual seed harvest time. 続きを見る

概要: This study evaluates land use transformation in Kandahar’s old city, also known as Ahmad Shahi city, the birthplace and first capital of modern Afghanistan. The city consists of four rectangular quarters and is surrounded by a high strong mud wall, entrance gates, and a moat. In the early 20th century, the city experienced significant and arbitrary expansion, which certainly affected the urban fabric of the area, the streets were widened, and the city wall, towers, and gates were demolished, and the area was added to the construction of new government buildings, commercial establishments, and residential plots. This study aims to evaluate the alterations in the old city’s urban morphology, culture, and sociology by conducting a comparative analysis of three maps from different time periods and considering various factors within the target area. 続きを見る
