Bionomical research on the continental shelf of the Oran‘s Gulf enabled us to study the Annelida macrofauna. Sampling sites were selected according to the bathymetry, which was divided into eight transects. Collected samples with the Aberdeen grab separated the Polychaeta Annelids from other zoological groups. 1571 Annelida Polychaeta were inventoried and determined by the species, including ten orders (Amphinomida, Capitellida, Eunicida, Flabelligerida, Ophelida, Oweniida, Phyllodocidae, Sabellida, Spionida, Terebellidae), 24 families, 84 genus and 74 species. The analyzed taxa highlighted the dominant and main species on the bottom of the Gulf, including Hyalinoecia bilineata, which appeared as the major species, Eunice vittata, Chone duneri, Glycera convoluta, Hyalinocea fauveli, Pista cristata, Lumbrinerris fragilis and Chloeia venusta.

The aim of this study was to assess the discriminability of the stocks of the round goby Neogobius melanostomus based on the shape of its otoliths. Recent otolith-shape-based species and stock discrimination studies were using otolith contours in sagittal plane and we are following this approach. We hypothesized the possibility of existence of several geographically separated populations of the round goby. Round gobies have been sampled from different locations of the North-Western Black Sea, otoliths were removed in course of the full biological analysis and photographed in sagittal plane. Principal components of the otolith contour were processed by linear discriminant analysis aiming to cross-validate the discriminability of round gobies placed at different geographical locations. This would allow demonstration of different stocks or populations. This research allows to conclude the limited applicability of otolith contours for discrimination of stocks or populations of round goby based on multiple annual samples. However, neither classification matrices of discriminant analysis nor cluster analysis dendrograms showed a single pattern except for the high year to year otoliths variability. This allows to hypothesise a strong response of contour formation to habitat and feeding conditions. However, this assumption needs to be verified by further studies.

The study of the nesting birds of the coastal riparian zones in Great Kabylia in Algeria, allowed us to identify 45 species of birds, belonging to 12 orders and 26 families. The richest site in terms of species is Takdempt (31 species). The lowest diversity is noted at the level of Boudouaou wadi with 16 species. The values of the Shannon-Weaver diversity index (H') for all sites are quite high (≥3 bits). Concerning the global abundance of avifauna, the site that represents the highest centesimal frequency is that of Takdempt (20.87 %) and this is due to the presence of a colony of Bubulcus ibis (Linnaeus, 1758). The bird communities of the sampled sites are not identical, but the degree of similarity, in general, is quite high (≥ 50 %). The main factors controlling the diversity and the structure of the avifauna of Great Kabylia coastal riparian zones are represented by vertical and horizontal vegetation structure

There is a specific feature in the developmental biology of oviparous snakes: embryos in the eggs, which were just laid, have already undergone significant development. This fact makes it significantly complicated to obtain data on organs’ development at early stages of embryogenesis. In addition, the fertilization time and the duration of snake pregnancy in the wild are unknown. In order to obtain the embryos of an oviparous grass snake Natrix natrix (Linnaeus, 1758) at successive developmental stages with minimal harm to gravid females we used caesarean section. The past known experience of performing caesarean section in snakes and anesthesia in reptiles were used. All the embryos were taken from the upper oviduct of a female simultaneously; in this way we eliminated the influence of medications on embryos’ development. The described method is valuable when it is necessary to obtain snake embryos and to preserve the life of the female and, possibly,its reproductive ability.

Important vertebrate fossil remains were collected in the Pohang Basin in South Korea for many decades, but only few have been described up to now. Here, three deep-sea shark teeth are described, which most likely derived from the Duho Formation (middle Miocene) near Pohang City, South Korea. One of the teeth is identified as belonging to the genus Mitsukurina, while the others are assignable to Dalatias. None of these taxa were previously reported from the Korean Peninsula. The occurrences of these deep-water fishes in the Pohang Basin support the hypotheses that the Duho Formation was deposited in a deep-sea environment, and sharks, even including benthopelagic forms were already widely distributed throughout the East Sea when this sea was still developing.

Monitoring studies of the species diversity in marine ecosystems provide important data on ecological changes caused by global warming and anthropogenic influence. The present work was aimed to analyze the species diversity of the helminths parasitic in teleost fishes inhabiting the area near the Ukrainian Antarctic Station “Akademik Vernadsky” (Galindez Island, Argentine Islands, West Antarctica). During April–January of 2014–2015 and 2019–2020, 156 specimens of six fish species (Notothenia coriiceps, N. rossii, Chaenocephalus aceratus, Parachaenichthys charcoti,Trematomus bernacchii, and Harpagifer antarcticus) were examined. Totally, 21,166 specimens of 31 helminth species were collected and assigned to five taxonomic groups: Monogenea (1 species), Digenea (10), Nematoda (5), Cestoda (4), and Acanthocephala (11). Twenty-six helminth species were found in N. coriiceps, 14 in N. rossii, 27 in P. charcoti, 23 in Ch. aceratus, 16 in T. bernacchii, and six in H. antarcticus. Larval stages of anisakid nematodes prevailed in the helminth community of Ch. aceratus (66 %) and P. charcoti (40 %), while other fish species were mostly infected with acanthocephalans,trematodes and cestodes. The present data on the species diversity of helminth communities can be used as a baseline for long-term monitoring studies of fish parasites in the region of the Argentine Islands.

The Pied Avocet (Recurvirostra avosetta Linnaeus, 1758) is a sedentary species in Northeastern Algeria, although numbers present increase during spring and summer. Nesting occurs on the dikes and lakes placed at the different pools of the saltpans. In this study, the breeding ecology of the Pied Avocet was studied during the 2017 breeding season in Tiffech lake wetland (868 m in elevation), Northeastern Algeria. The Pied Avocets arrived, at Tiffech Lake in early February and usually spent a few days in flocks before dispersing to set up territories. Egg-laying occurred from 11 April to 21 June, with two distinct peaks (last 15 days of April and May) and incubation period was 27.0 days. The present study indicates the expanded, breeding season. Clutch and egg size of this high-elevation population was comparable to lowland counterparts. Hatching success was 85.77 % and mean net productivity was 0.63 chicks per nest. Entire nest failure from human predation and sheep grazing was responsible for most egg losses.

Archaic song dialect of Chaffinch (Fringilla coelebs Linnaeus, 1758) is located in the Lower-Dnipro Area. To describe it, we recorded 11673 songs of 2008 males from 43 localities in Southern Ukraine during 2004–2015. This dialect has compound spatial structure and connects with other dialects forming a well developed contact area with them. Its core was located in old forests of the lower stream of the Dnipro River. It has spread from them to the new forests in their outskirts. The complex is separated at dialect level in the cluster analysis. It includes considerable number of original song types. Their elements and structure demonstrate archaic features similar to those of other southern complexes but more modern than the old Carpathian and Danube dialects. It occupies the intermediate position between them and modern dialects of the Forest and Wood-and-Steppe Ukraine by the structure of song and is similar to the dialect of Crimean Chaffinch and the song complex of South-Eastern Ukraine.

In this study, we report the rearing of Brachyopa panzeri Goffe, 1945 from larva and elucidate its life circle with a duration of the pupal stage for the first time. We describe the puparium of B. panzeri of which the morphology was unknown prior to the current study. The study of the larva of B. panzeri showed discrepancies between our observations and its original description. These allow us to redescribe the larva, explaining the uncertainties that have existed in the literature since the description of the larva. We clarify larval morphology and propose new characters for identification with the map of its chaetotaxy. Morphological features of the larva and pupa are illustrated using both light- and electron microscopy. Additionally, we reared the endoparasitoid wasp Tetrastichus brachyopae Graham, 1991 (Hymenoptera: Eulophidae) from B. panzeri for the first time. Moreover, T. brachyopae is a new species for Ukraine.
