Studies on the thelytokous parthenogenesis in the scorpion, Liocheles australasiae (Fabricius) [PDF]

open access: yes, 2001
本論文は,サソリ類(蛛形綱,サソリ目)において初めて,雌性産生単為生殖の過程および機構を,組織学的観察,核学的観察,および核DNA量の測定にもとづいて解明したものである。 ヤエヤマサソリはアジア・太平洋地域に広く分布し,沖縄県八重山諸島を分布の北限とする胎生のサソリである。西表島のヤエヤマサソリ個体群が雌性産生単為生殖によって維持されていることは,野外調査および実験室内での個別継代飼育によって明らかにされていたが,母虫卵巣内において卵の成熟から発生の単為的開始に至る過程および機構については,不明であった。

Novel microsatellite DNA markers indicate strict parthenogenesis and few genotypes in the invasive willow sawfly Nematus oligospilus [PDF]

open access: yes, 2017
Invasive organisms can have major impacts on the environment. Some invasive organisms are parthenogenetic in their invasive range and, therefore, exist as a number of asexual lineages (=clones).
