Faunistical Overview of Calanoid Copepods (Crustacea) from Continental Waters of Ukraine
Faunistic overview together with updated checklist, comprising 38 species and 2 subspecies of calanoid copepods inhabiting fresh and brackish Ukrainian waters classified in three families and twelve genera is provided. The only freshwater calanoid species endem...
We measured the survival of subitaneous eggs of two calanoid (Eudiaptomus gracilis, E. graciloides ) and two cyclopoid (Cyclops abyssorum, Macrocyclops albidus ) freshwater copepods after they had been consumed by fish. Unexpectedly, over 80% of the calanoid eggs and 30-59% of the cyclopoid eggs were morphologically intact in fish feces. Subitaneou...
Calanoid copepods with different life cycle strategies demonstrate varied velocity in the utilization of energy resources during
starvation. Tis study analyzes the influence of multiday starvation on the rate of total, basal and active energy metabolism in adult
females of two Marmara Sea and one Baltic Sea species of copepods; epiplanktonic Acartia...
Sinodiaptomus sarsi is found for the second time in Ukraine, in the three artificial lakes of the one of capital Kyiv city`s park, Nyvky, after its first record in the Carpathian Mountain region near Slovakian border in 2016 by Dr. Mykitchak. Our morphological study showed the similarity between the specimens of S. sarsi found in Kyiv with existing...

Climate change-related heatwaves are major threats to biodiversity and ecosystem functioning. However, our current understanding of the mechanisms governing community resistance to and recovery from extreme temperature events is still rudimentary. The spatial insurance hypothesis postulates that diverse regional species pools can buffer ecosystem f...
Climate change-related heatwaves are major recent threats to biodiversity and ecosystem functioning. However, our current understanding of the mechanisms governing community resilience (resistance and recovery) to extreme temperature events is still rudimentary.

Abiotic (water quality) and biotic (Phyto-, zooplankton and benthos) factors in the Kantivka fattening pond the Khmelnitskrybhosp Private Joint-Stock Company were studied during the vegetation seasons in 2020. The aquaculture objects in the pond are cyprinid fish species (carp, grass carp, silver carp, pike). The ecological conditions of the pond w...
In autumn 2020, Sinodiaptomus sarsi (Rylov, 1923) was found in three artificial ponds in one of the capital`s parks, the Nyvka Park, in Kyiv, Ukraine (Svetlichny, Samchyshyna, 2021). This was a second finding of the species after the record in the West Ukraine (Mykitchak, 2016) which was in fact a first finding for Europe.
As known, the term invasi...
The brackish water calanoid copepod Eurytemora velox has become a widespread species in inland fresh waters of Ukraine. Nowadays it is one of the dominant crustacean species in the littoral zooplankton of the main Ukrainian rivers: Dnieper, Danube and Pivdenny Buh. We present a survey on E. velox localities in, mainly, fresh waters of Ukraine, data...
Twenty species of cladocerans (Сrustacea, Cladocera) were identified from ten lentic water bodies of
Kyiv city. The biggest species richness along with the lowest saprobity index is revealed for
Rusanivske lake (water quality class – II, clean). The quality of water of most studied Kyiv lakes,
which has been evaluated by Pantle-Buck saprobiological...

Chorion Structure of Diapause and Subitaneous Eggs of Four Diaptomid Copepods (Calanoida, Diaptomidae): SEM Observations
Scanning electron microscopic examination of diapause eggs of freshwater Calanoida Hemidiaptomus amblyodon Marenzeller, Eudiaptomus vulgaris (Schmeil), E. graciloides (Lilljeborg) and subitaneous one s of E. gracilis (Sars) is de...
Conception of Crossed Populations: Application in Cyclopoida Taxonomy
The conception of crossed populations in wide practice of taxonomic investigations in Cyclopoida is used for the first time. Applying this conception in taxonomy of cyclopoid copepods we based on revealed facts of the coexistence of sibling species which keep a little morphologic...
First record of this species from Ukraine is mentioned by S.S. Smirnov as Branchipus alpinus Colosi, 1922 from Crimean peninsula (Smirnov, 1940). He shortly noted that this species is differed from Branchipus stagnalis (Linnaeus, 1758) by armed abdomenal segments. It was shown later B. stagnalis is a younger synonym of Branchipus schaefferi Fischer...
We analysed circumpolar samples from 68 lakes within the 10°C-July isotherm from Arctic Canada, Nunavut, Greenland, Svalbard,
Eastern Siberia, the Beringia region, and Alaska. In total, we found 3 species of Anostraca, 17 of Diplostraca, 1 species
of cyclopoid and 14 species of calanoid copepods. Our study identifies a wider distribution for some c...

Ecological Characteristic of Calanoids (Copepoda, Calanoida) of the Inland Waters of Ukraine
The article presents analyze of known published data and own observations on ecology of freshwater and brackish calanoid copepods of fauna of Ukraine. The briefly characteristic of main types of waterbodies inhabited by calanoids is given. The relation of s...

We studied grazing on the green alga Scenedesmus obliquus and the cyanobacterium Planktothrix agardhii (a microcystin-producing and a microcystin- free strain) by three different filter-feeders to compare the efficiency with
which these grazers remove Planktothrix from the water. The filterfeeders were two mussel species (the invasive species Dreis...
4 species of two families of Calanoida
(Diaptomidae and Temoridae) were found in the 11 lakes: Eudiaptomus gracilis (Sars), E. graciloides
(Lill.) E. coeruleus (Fisch.) and Heterocope appendiculata Sars. The last records confirm belonging the Shatski
Lakes to the Baltic Province of the North-European superprovince. The illustrated redescription of...
The process of enrichment of the fresh-water fauna as the result of expansion of sea invaders is well traced on the example of Ponto- Caspian species. One of them - Eurytemora velox (Lill.) - was recorded repeatedly in the Dnieper River and its large tributaries much northern to the limits of maximal transgrasion of Azov-Black Sea basin. Appearance...

I will appreciate if someone can help me to identify larvae of Polychaetes I found them in zooplankton samples quite frequently. This sample is from Bransfield Strait. Aslo I will be very grateful if someone can share an identification key or taxonomic guides how to identify polar polychaetes. I also have more pics from Arctic and Antarctic region and I need key for both Poles.
Thank you very much in advance,

I will appreciate if someone of foraminifer experts can help me to identify these species. I am copepodologist, but now met foraminifers in the sample from Amundsen Sea and have to know what the species they are? I guess might be that one, the spinose species, looks like Globigerina falconensis? Where are some others but seems they looks differ... I am not sure...

Sample was from mountain lake in Ukraine (april 2015, under ice).
