内容記述
内容記述タイプ Abstract
内容記述 In September 2021, Neocardina sp. as a serious invasive alien freshwater shrimp were collected in Kakinohana spring, Okinawajima Island, central Ryukyus, Japan. These shrimp were first recorded on Okinawajima Island and Ryukyu Archipelago. The phylogenetic tree based on the Bayesian inference of nucleotide sequences in the COI region of mitochondrial DNA was used to identify this shrimp as N. devidi type II (N. devidi koreana?). This species are highly reproductive and are likely to have a negative impact on the ecosystem as well as on native shrimp. Also, same genus shrimp are distributed in Ishigakijima and Iriomotejima Islands, hybridization and extinction are feared by the invasion of this species.
内容記述タイプ Abstract
内容記述 2021 年9 月〜10 月に沖縄島南部の垣花樋川において国外由来の外来淡水エビのカワリヌマエビ類の一種Neocardina sp. を138 個体採集した.この採集記録は,沖縄島で初めてだけでなく,琉球列島でも初記録である.ミトコンドリアDNA のCOI 領域における塩基配列のベイズ推定を用いた系統樹によって,シナヌマエビN. devidi のⅡ型系統(コウライヌマエビ?)とした.餌資源を共有する在来のコエビ類や生態系に負の影響を与える可能性がある.さらに石垣島と西表島には同属のイシガキヌマエビとイリオモテヌマエビが分布することから,シナヌマエビをはじめとするカワリヌマエビ類の侵入によって雑種化や絶滅が危惧されるため,行政によるモニタリングを喫急に開始するべきである.
