Abstract:
Invasive non-native freshwater mollusks are a growing concern in South America, with 16 species already recorded in the region. Among them, Sinotaia quadrata has only been documented in Argentina, for the first time in the Punilla Valley, Córdoba (2009) and La Plata, Buenos Aires (since 2015). In this study, we report the presence of S. quadrata in two additional areas, the Río de la Plata River and a stream (unnamed) in the Paraná River basin, two of the most significant rivers in South America, located in the provinces of Buenos Aires and Entre Ríos, respectively. These new records confirm the invasive nature of this species, which has also been identified in Europe, the United States, and Africa in recent years. The findings of this study highlight the need for continued monitoring and management of invasive species in South America\'s freshwater ecosystems.
摘要:
入侵的非本地淡水软体动物在南美日益受到关注,该地区已经记录了16种。其中,中诺泰四重奏只在阿根廷有记载,第一次在Punilla山谷,科尔多瓦(2009)和拉普拉塔,布宜诺斯艾利斯(自2015年起)。在这项研究中,我们报告了S.quadrata在另外两个区域的存在,拉普拉塔河和巴拉那河流域的一条小溪(未命名),南美洲最重要的两条河流,位于布宜诺斯艾利斯和恩特雷里奥斯省,分别。这些新记录证实了这个物种的入侵性质,这在欧洲也被发现了,美国,近年来,非洲。这项研究的结果强调了继续监测和管理南美淡水生态系统中入侵物种的必要性。
