Abstract

The hydrobiological studies carried out in 2017 and 2018 yielded new information on the distribution of the alien species Kellicottia bostoniensis (Rousselet, 1908), discovered in five different-type rivers. This species was found in these rivers for the first time. In the Gnilichka, Vyunitsa, Chernaya, and Kerzhenets rivers and also in the Cheboksary Reservoir, the rotifer was reregistered. The lower reach of the Vetluga River is at the same time the easternmost and northernmost location where this species was found in Nizhny Novgorod oblast. The paper analyzes the findings of K. bostoniensis in the floodplain lakes of the Kerzhenets River, which are new habitats of this species in Nizhny Novgorod oblast. It has been found that rotifers are common in water bodies with various depths and different morphometric and physicochemical parameters. For the first time K. bostoniensis is registered in the water bodies of European part of Russia with a water color index of more than 1000 degrees (Lake Novaya Staritsa—1245.0 deg), as well as in the waters with a low content of dissolved oxygen (0.2 mg/L—Lake Novaya Staritsa).

下诺夫哥罗德州发现外星轮虫Kellicottia bostoniensis(Rousselet,1908)(轮虫:Monogononta:Brachionidae)的新信息

摘要

2017年和2018年进行的水生生物学研究提供了有关在五种不同类型河流中发现的外来物种Kellicottia bostoniensis(Rousselet,1908)的分布的新信息。该物种是在这些河流中首次发现的。在Gnilichka,Vyunitsa,Chernaya和Kerzhenets河流以及切博克萨雷水库,轮虫重新登记。同时,在下诺夫哥罗德州发现维特卢加河的最下游和最东端和最北端。本文分析了波氏梭菌的发现在下诺夫哥罗德州的克尔珍涅茨河泛滥湖中,是该物种的新栖息地。已经发现轮虫在具有不同深度和不同形态和理化参数的水体中是常见的。首次K. bostoniensis被登记在具有大于1000度(湖新地斯塔里察-1245.0度),水颜色索引俄罗斯的欧洲部分的水体,以及在水与溶解的氧的含量低(0.2 mg / L-Novaya Staritsa湖)。
