Описание
The copepod Boeckella poppei (Mrazek, 1901) (Calanoida: Centropagidae) is one of the Maritime Antarctic’s most common freshwater zooplankton species. It was first reported from the Antarctic in 1961–1962 on Signy Island (South Orkney Islands). Although the in situ refugia hypothesis suggests that this species survived in regional refuges throughout multiple Pleistocene glacial cycles. Since then, its presence has been confirmed from many locations in the Maritime Antarctic. The species is also present on sub-Antarctic South Georgia and in lakes around the Prince Charles Mountains in Continental Antarctica, and in southern South America. However, in the central part of the western Antarctic Peninsula, specifically in the Wilhelm Archipelago, there have to date been only a few disjointed records of the species and its distribution here has not been documented in any detail beyond being noted as numerous both north and south of the Ukrainian Antarctic Akademik Vernadsky station. Here, we report B. poppei in 51 samples obtained from 23 lakes on eight islands in the Wilhelm Archipelago. Living specimens were observed both in the ice-free summer season and well after the formation of surface ice on water bodies. Adult specimens were present in all samples, while the copepodid stages were only rarely observed and nauplii were not encountered.

Методы сбора
We condensed a known volume of water through a small Apstein net with a mesh size of 100 μm. If we could not concentrate the sample in situ, the water was transported to the laboratory in tanks made of chemically inert plastic and filtered through the gauze with a mesh size of 100 μm. If the lake was covered with ice, a well was cut to sample it. A sample was collected from 5 to 50 liters of water, depending on the size of the reservoir and the visible number of copepods inside. The remaining water was removed using a pipette with its tip covered by gauze. The residue was fixed in 96% ethanol, signed, and transported to Ukraine for analysis.
| Охват исследования | The study was done on 114 samples of invertebrates collected in 2005–2006, 2008–2009, 2015–2019, and 2021–2023 UAEs. We collected the material mostly within the Wilhelm Archipelago, with some taken on the South Shetlands, King George Island, Nelson Island, and De caption Island. |
