| description | Background. Studying the fauna of aquatic organisms in various types of ecosystems
within the region is necessary to understand the role of biodiversity in the ecosystem
functioning. The purpose of the study is to conduct an inventory of the fauna of zooplankton
organisms in the aquatic ecosystems of Penza region. Materials and methods. To describe
the species composition and occurrence of zooplankton organisms, we used the original
database on the species structure of zooplankton communities accumulated over the
period 1993–2022. The species composition of zooplankton communities was analyzed in
seven groups of different types of water bodies: watercourses with insignificant anthropogenic
influence, watercourses with high anthropogenic influence, floodplain water bodies,
watershed water bodies, dammed water bodies, dug water bodies, and the Penza reservoir.
Results. During 30 years of research, 387 zooplankton species were found in the Penza region:
Rotifera – 264, Cladocera – 75, Copepoda – 48. 18 % of zooplankton species were
found in all types of ecosystems. About 45% of zooplankton species were very rare (occurrence
less than 1%), among them the cladocera Eurycercus macrocanthus, which is also
rare for the European part of Russia, and the rotifer Aspelta angusta, recorded in the Volga
region for the first time. Some species belong to the southern complex: the rotifer Keratella
valga and cladocerans Dunhevedia crassa, Tretocephala ambigua. For the first time, the
rotifer Synchaeta kitina was found in the city Arbekovsky pond, which supplements the list
of cold-loving species (genus Notholca, Conochiloides natans, Synchaeta tremula, Cyclops
kolensis) discovered earlier. Conclusions. Due to the fact that in recent years the
amount of studied aquatic ecosystems has been significantly expanded, the list of zooplankton
species has increased by 126 taxa compared to that noted 17 years ago (Stoyko and
Mazei, 2005). |
