Effects of co-occurrence of invading Procambarus clarkii and Pomacea canaliculata on Vallisneria denseserrulata-dominated clear-water ecosystems: a mesocosm approach

Autor: Gao Jian, Yang Cheng, Zhang Zehui, Liu Zhengwen, Jeppesen Erik

Publikováno v: Knowledge and Management of Aquatic Ecosystems, Vol 0, Iss 422, p 29 (2021)

Single invaders often substantially alter ecosystems, but the potential impacts by multiple invaders remain understudied. The golden apple snail (Pomacea canaliculata) and the red swamp crayfish (Procambarus clarkii) are two widespread coinvaders. To
