    Limnetic zooplankton passing through a high-head dam and their fate in a river with high current velocity (Case of the Krasnoyarsk hydroelectric power station on the Yenisey river) / O. P. Dubovskaya, M. I. Gladyshev, O. N. Makhutova // Zhurnal Obshchei Biologii. - 2004. - Vol. 65, Is. 1. - С. 92-93 . - ISSN 0044-4596

Copepoda -- Heterocope
Аннотация: The vertical distribution of net zooplankton in head-water of Krasnoyarsk hydroelectric power station and its horizontal distribution in the tail-water were studied during two years in winter and summer seasons. In order to distinguish living and dead individuals the special staining was used. It was revealed that on average 77% of living plankton pass through high-head dam with deep water scoop to the tailwater. While passing through dam aggregates some individuals of the reservoir plankton are traumatized and die, that results in some increase of portion of dead individuals in the tail water near dam (from 3 to 6%). Alive zooplankton passed through the dam aggregates is eliminated under the Upper Yenisey highly turbulent conditions. There is approximately 10% of it in 32 km from the dam if compare with biomass in 20-40 m layer of reservoir, the portion of dead increases to 11%. The biomass of zooplankton suspended in the water column of the tail-water sometimes increases (till > 1 g/m3) due to large Copepoda Heterocope borealis, which inhabits near-bottom and near-shore river zones and can be found in the central part of the river during reproductive period. Limnetic zooplankton from the reservoir cannot be considered as important food for planktivores in the tail-water.

Аннотация: Двухлетние исследования сетного зоопланктона в верхнем и нижнем бьефах Красноярской ГЭС с учетом специальной дифференцировки на живых и мертвых показали, что через высоконапорную плотину с глубинным водозабором в нижний бьеф проходит в среднем 77% биомассы живого зоопланктона водохранилища с глубин водозаборных отверстий гидроагрегатов (20-40 м). При транзите через агрегаты плотины происходит травмирование и гибель некоторой части планктонных ракообразных: доля мертвых в общей биомассе зоопланктона возрастает в среднем в 2 раза (с 3 до 6%). Прошедший через агрегаты плотины живой зоопланктон не выживает в условиях Верхнего Енисея с высокой турбулентностью потока. В 32 км от плотины его остается в среднем около 10% ('ПРИБЛ='10 мг/м{3}) от биомассы в слое 20-40 м водохранилища; доля мертвых возрастает в среднем до 11%. Биомасса транзитного зоопланктона в нижнем бьефе иногда увеличивается (до конц-ии 1 г/м{3}) за счет крупного рачка Heterocope borealis, к-рый заселил придонно-прибрежные зоны реки и в периоды размножения выносится на стержень. Лимнический зоопланктон из водохранилища не может рассматриваться как кормовой объект планктофагов в нижнем бьефе.

In order to distinguish living and dead individuals the special staining was used. It was revealed that on average 77% of living plankton pass through high-head dam with deep water scoop to the tailwater. While passing through dam aggregates some individuals of the reservoir plankton are traumatized and die, that results in some increase of portion of dead individuals in the tail water near dam (from 3 to 6%). Alive zooplankton passed through the darn aggregates is eliminated under the Upper Yenisey highly turbulent conditions. There is approximately 10% of it in 32 km from the dam if compare with biomass in 20-40 m layer of reservoir; the portion of dead increases to I M. The biomass of zooplankton suspended in the water column of the tail-water sometimes increases (till 1 g/m(3)) due to large Copepoda Heterocope borealis, which inhabits near-bottom and near-shore river zones and can be found in the central part of the river during reproductive period. Limnetic zooplankton from the reservoir cannot be considered as important food for planktivores in the tail-water.

    Biogeographic patterns of planktonic and meiobenthic fauna diversity in inland waters of the Russian Arctic / E. Fefilova, O. Dubovskaya, L. Frolova [et al.] // Freshw. Biol. - 2020, DOI 10.1111/fwb.13624 . - Article in press. - ISSN 0046-5070

cladocerans -- copepods -- rotifers -- spatial and temporal trends -- species richness
Аннотация: Broad-scale assessment of biodiversity is needed for detection of future changes across substantial regions of the Arctic. Presently, there are large data and information gaps in species composition and richness of the freshwater planktonic and meiobenthos communities of the Russian Arctic. Analysis of these data is very important for identifying the spatial distribution and temporal changes in species richness and diversity of rotifers, cladocerans, and copepods in the continental Russian Arctic. We investigated biogeographic patterns of freshwater plankton and meiobenthos from c. 67° to 73°N by analysing data over the period 1960–2017. These data include information on the composition of rotifers, cladocerans, and copepods obtained from planktonic and meiobenthic samples, as well as from subfossil remains in bottom sediments of seven regions from the Kola Peninsula in the west, to the Indigirka River Basin (east Siberia) in the east. Total richness included 175 species comprised of 49 rotifer genera, 81 species from 40 cladoceran genera, and 101 species from 42 genera of calanoid, cyclopoid, and harpacticoid copepods. Longitudinal trends in rotifer and micro-crustacean diversity were revealed by change in species composition from Europe to eastern Siberia. The most common and widespread species were 19 ubiquitous taxa that included Kellicottia longispina (Rotifera), Chydorus sphaericus s. lat. (Cladocera), Heterocope borealis, Acanthocyclops vernalis, and Moraria duthiei (Copepoda). The highest number of rare species was recorded in the well-studied region of the Bolshezemelskaya tundra and in the Putorana Plateau. The total number of copepod and rotifer species in both Arctic lakes and ponds tended to increase with latitude. Relative species richness of copepods was positively associated with waterbody area, elevation, and precipitation, while relative species richness of cladocerans was positively related to temperature. This result is consistent with known thermophilic characteristics of cladocerans and the cold tolerance properties of copepods, with the former being dominant in shallow, warmer waterbodies of some western regions, and the latter being dominant in large cold lakes and waterbodies of eastern regions. Rotifers showed a negative association with these factors. Alpha- and ?-diversity of zooplankton in the Russian Arctic were strongly related to waterbody type. Lake zooplankton communities were more diverse than those in pond and pool systems. Moreover, the highest ?-diversity values were observed in regions that showed a greater breadth in latitude and highly heterogeneous environmental conditions and waterbody types (Bolshezemelskaya tundra and Putorana Plateau). Redistribution of freshwater micro-fauna caused by human activities occurred in the 1990s and 2000s. As a result of climate warming, a few cladoceran species appear to have extended their range northward. Nevertheless, the rotifer and micro-crustacean fauna composition and diversity of the majority of Arctic regions generally remain temporally conservative, and spatial differences in composition and species richness are chiefly associated with the differences between the warmer European and colder east Siberian climates. © 2020 John Wiley & Sons Ltd.
