The invasive amphipod Gmelinoides fasciatus (Stebbing, 1899) was not previously recorded in the rivers of the Onega Lake basin, although it has spread widely in its littoral in recent years. In 2019 and 2020, this species was found to inhabit the estuarine zones of watercourses (the Rybreka River and the Drugaya River) at a considerable distance from the lacustrine littoral zone (0.5 and 1.7 km, respectively). It was revealed that G. fasciatus is included in the communities of both pools and riffles, and in some areas reaches dominant positions in the macrozoobenthos, which indicates the possibility of further expansion of its range due to the river ecosystems of the region.

The article presents data on the study of the diversity of crustacean communities in the Moscow-river basin. Two most common are two species of amphipods, invasive species Gmelinodes fasciatus and the native species Gammarus lacustris, were detected and studies during the study. However, the number of one of the most important bioindicator species of crustaceans, Asellus aquaticus found in our samples is insufficient for quantitative conclusions. At the same time, population of G. fasciatus can be characterized as stable at all studied stations and the species can be used as bioindicator of the natural condition of the river flowing within the Moscow City. The species seems to be significantly less sensitive to environment conditions and especially anthropogenic pollution than the native amphipod species G. lacustris and can successfully replace A. aquaticus as bioindicator species in the area where the latter species is absent. Thus, a new bioindicator pair Gammarus lacustris / Gmelinoides fasciatus is suggested for using in estimation water pollution In European part of the Russian Federation and adjacent areas.

Since the middle of the ХХ century, the rapid spread of exotic species and their successful penetration in natural and artificial ecosystems has led to significant environmental changes all over the world [1, 2]. As it was pointed out by many researchers, biological invasion by alien species is one of the main threats to biodiversity [3, 4, 5, 6, 7]. Gmelinoides fasciatus (Stebbing 1899) attracts special attention due to the fact that it is the most successful alien species among other invaders in aquatic ecosystems in Eurasia. This invasive amphipod of Baikalian origin was first recorded in Lake Onego in 2001 by Berezina and Panov [8]. The results of the present study indicate that the invader significantly expanded its areal in Lake Onego during the last 15 years. At present amphipod G. fasciatus is dominant on the biomass among macrozoobenthos community in littoral biotopes of some islands and east part of the Lake. In Lake Onego the invader has a one-year life cycle with the generations of the previous and current year. Seasonal dynamics of the amphipod abundance in Lake Onego has two peaks during the vegetation period. According to our data G. fasciatus successfully reproduces in the new environment and shows stable sexual structure with sex ratio of approximately 1:1. Female fecundity of the amphipod in the Lake varied from 3 to 22 eggs per female, the average variation of fertility is 9 eggs per female. Revealed data of G. fasciatus abundance and biomass in Lake Onego are comparable with those for other water bodies where this amphipod species was successfully established earlier.

The following paper deals with the study of the Sperrings culture. More than a decade has passed since the last general publications on early Neolithic of Karelia. During this period, new sites of the Sperrings culture have been discovered and studied, first AMS-dating has been received from the ceramic fragments, monuments of the early Neolithic in the neighboring territories have been studied. As a result of two decades of the archaeological research in Karelia more than a dozen of new monuments were discovered and investigated, including poorly explored areas of the Northern Ladoga and Karelian isthmus. The Sperrings culture centre is the Onega lake basin, where more than 200 settlements are known. The existence period of the Sperrings culture in the Onega lake basin on the basis of AMS-dates is 5306-4250 cal BC. These data are also consistent with AMS-dating of bones of Koirinoya III settlement in the North Ladoga area. The Sperrings ceramics appeared on the territory of Karelia at the same time.
