The Yanbaru whiskered bat (Myotis yanbarensis) is a species of vesper bat in the genus Myotis .
It is known only from three islands of the Ryukyu Archipelago, south of Japan, Okinawa (where the Yanbaru forest is situated), Amami Ōshima, and Tokunoshima. [2] The species has been classified as Critically Endangered by the IUCN. [1]
When described, it was placed into the subgenus Selysius , [2] although some have argued that it is not a valid subgenus. [3] It is closely related to the frosted myotis, which is found on mainland Japan. [4] [5] Its species name, yanbarensis, is a reference to Yanbaru, the forested part of northern Okinawa Island where this species is found. [2]
Its dorsal hair, ears, and flight membranes are black. Its guard hairs are metallic silver at the tips. Its fur is overall soft and silky. Its snouts are long and horizontal. The uropatagium attaches to the first toe. The forearm is 36.5–37.5 mm (1.44–1.48 in) long. Its ears are 14 mm (0.55 in). Its tragi are 7 mm (0.28 in), and tapers gradually at the tip. The braincase is small relative to its skull. [2]
It is only found in the fragments of mature forest remaining on Okinawa Island, Tokunoshima, and Amami Ōshima. On Okinawa Island, it is found on United States military property. On Amami Ōshima, its habitat occurs within Amami Guntō Quasi-National Park. During the day, it roosts in hollow trees. [1]
This species was evaluated for the first time by the IUCN in 2000, when it was described as data deficient. It was listed as critically endangered in 2008, which was maintained in the 2019 evaluation. It is listed as critically endangered because it only occurs on three islands, its extent of occurrence is less than 100 km2 (39 sq mi), and its habitat size and quality is being lost. Deforestation is a major threat to its continued existence. [1]
Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat families, specialised in many forms to occupy a range of habitats and ecological circumstances, and it is frequently observed or the subject of research. The facial features of the species are often simple, as they mainly rely on vocally emitted echolocation. The tails of the species are enclosed by the lower flight membranes between the legs. Over 300 species are distributed all over the world, on every continent except Antarctica. It owes its name to the genus Vespertilio, which takes its name from a word for bat, vespertilio, derived from the Latin term vesper meaning 'evening'; they are termed "evening bats" and were once referred to as "evening birds".
Amami Ōshima, also known as Amami, is the largest island in the Amami archipelago between Kyūshū and Okinawa. It is one of the Satsunan Islands.
The mouse-eared bats or myotises are a diverse and widespread genus (Myotis) of bats within the family Vespertilionidae. The noun "myotis" itself is a Neo-Latin construction, from the Greek "muós and "oûs", literally translating to "mouse-eared".
Tokunoshima, also known in English as Tokuno Island, is an island in the Amami archipelago of the southern Satsunan Islands of Kagoshima Prefecture, Japan.
The velvety myotis, is a species of vesper bat from South America.
The Atacama myotis is a species of vesper bat in the family Vespertilionidae. It is found in Chile and Peru, an example ecoregion of occurrence being the Chilean matorral.
The frosted myotis is a species of vesper bat. It is found only in Japan.
Myotis vivesi, the fish-eating bat or fish-eating myotis, is a species of bat that lives around the Gulf of California, and feeds on fish and crustaceans. It is the largest species of the genus Myotis in the Americas, and has exceptionally large feet, which it uses in hunting. It was described in 1901 by Auguste Ménégaux. It was previously considered the only member of the Myotis subgenus Pizonyx, but Pizonyx is now considered to contain all American Myotis species, along with two Eurasian ones.
Yambaru (山原) is the Okinawan and Kunigami name given to the forested northern part of Okinawa Island in Japan. Spanning the northern villages of Higashi, Kunigami, and Ōgimi, Yambaru contains some of the last large surviving tracts of subtropical rainforest in Asia, with many endemic species of flora and fauna. Many southerners fled to the area for refuge during the Battle of Okinawa. In 2016, Yambaru National Park was established and the area was included in a submission for inscription on the UNESCO World Heritage List.
The Armenian whiskered bat, also known as the Hajastan myotis or the Armenian myotis, is a species of bat from the family Vespertilionidae. The Armenian whiskered bat was formerly included as a part of the whiskered bat, but was considered distinct in 2000 as a result of morphologic comparison.
The Northern Ryukyuan languages are a group of languages spoken in the Amami Islands, Kagoshima Prefecture and the Okinawa Islands, Okinawa Prefecture of southwestern Japan. It is one of two primary branches of the Ryukyuan languages, which are then part of the Japonic languages. The subdivisions of Northern Ryukyuan are a matter of scholarly debate.
Yambaru National Park is a national park in Okinawa Prefecture, Japan. Established in 2016, it is located in and around the forested region of Yambaru at the northern end of Okinawa Island. The park comprises a land area of 13,622 ha in the villages of Kunigami, Ōgimi, and Higashi together with 3,670 ha of the surrounding waters. The day of establishment, 15 September, coincides with the anniversary of the 1983 discovery of the endangered endemic Yambaru long-armed scarab beetle .
Amami Guntō National Park is a national park in Kagoshima Prefecture, Japan. Established in 2017, the park comprises a land area of 42,181 ha and a sea area of 33,082 ha. The national park includes areas of these islands: Tokunoshima, Kikai, Amami, Yoron, Okinoerabujima, Uke Island, Kakeromajima and Yoroshima.
Amami-Ōshima Island, Tokunoshima Island, northern part of Okinawa Island, and Iriomote Island (奄美大島、徳之島、沖縄島北部及び西表島) is a serial UNESCO World Heritage Site consisting of five component parts on four Japanese islands in the Ryukyu Chain of the Nansei Islands. The site was selected in terms of biodiversity for having a diverse ecosystem of plant and animal species that are unique to the region.
In the context of the conservation of endangered species in Japan, and the list below, Endangered Species are those designated by Cabinet order in accordance with the 1992 Act on Conservation of Endangered Species of Wild Fauna and Flora. There are two main types of Endangered Species, National Endangered Species (国内希少野生動植物種) (NES) and International Endangered Species (国際希少野生動植物種) (IES), although there is also provision for Temporarily Designated Endangered Species (緊急指定種), as well as Designated Nationally Endangered Species (特定国内希少野生動植物種)—and businesses dealing with Designated Nationally Endangered Species (特定国内種事業) and Designated Internationally Endangered Species (特定国際種事業).
