When studying the morphogenesis of olfactory analyzer in fishes, it is crucial to determine the exact time at which the placode, olfactory pit, and olfactory lamellae are formed. Among a large number of fixatives, 10 % formalin and Bouin’s solution are most commonly used to study the olfactory organ of Teleostei. Use of inappropriate fixative or incorrect fixation process can damage the structures under investigation and, as a result, will lead to the misinterpretation of results. The influence of the fixatives on the preservation of olfactory structures of European weather fish Misgurnus fossilis (Linnaeus, 1758) as close as possible to their living state is studied. Similar stages were fixated in Bouin’s solution as well as in 10 % formalin. Histological preparations for the light microscopy were made using the standard histological methodologies. At all analyzed stages of European weather fish development, histological preparations are more accurate, reliable, and informative aft er the fixation in Bouin’s solution. Aft er the fixation in 10 % formalin, it is impossible to determine the moment at which the olfactory pit begins to form. Because of the artifacts of olfactory epithelium appearing aft er fixation in 10 % formalin, the timing of olfactory lamellae formation could be easily misinterpreted and a comparative analysis on the morphogenesis of the olfactory analyzer becomes more complicated. Given our observations, a thorough revision of previous literature has to be performed to derive accurate evolutionary and morphological interpretations.","PeriodicalId":206426,"journal":{"name":"Vestnik Zoologii","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126807580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the years 1978–2014, 146 ungulates of 24 species (16 species of Bovidae, 4 — Cervidae, 4 — Camelidae) were examined by partial helminthological dissection; more than 402,700 specimens of helminths were collected and identified. The purpose of the present study was to summarize these data and analyze the species diversity in exotic ungulates. Totally, 38 species of helminths: 3 species of Trematoda, 6 — Cestoda, 29 — Nematoda were found. Ungulates from the family Bovidae were the most infected; they harbored 36 species of helminths, 1–18 species per host. In Camelidae, 15 species were found; 3–10 species per host. Cervidae harbored 9 species; 1–6 species per host. The highest species diversity was detected in the ungulates introduced from regions with climatic conditions similar to those in southern Ukraine: saiga antelope (19 species), European mouflon (18), Barbary sheep (18), and markhor (17). Ten species typical for domestic ruminants (Haemonchus contortus, Nematodirus sp., Aonchotheca bovis, Moniezia expansa, Oesophagostomum venulosum, Ostertagia circumcincta, Trichostrongylus axei, T. colubriformis, T. probolurus and Trichuris ovis) dominated in the parasite communities. Our results indicated reduction in the species diversity and alteration of the parasite community structures in these exotic ungulates kept in the Askania-Nova Reserve compared to their natural habitats.","PeriodicalId":206426,"journal":{"name":"Vestnik Zoologii","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131846682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Isolated mandibles and many individual teeth were found at this locality, with some teeth in situ corresponding morphologically with the mandible and skull of Devinophoca claytoni, and others perfectly associating to the mandible and skull of the recently described Devinophoca emryi. Based on this material, two species of the previously unknown phocid subfamily Devinophocinae Koretsky et Holec, 2002 have been described. However, the mandibular morphology of the type species Devinophoca claytoni has remained unknown. Here, we present a first description of the mandible of this species. Morphological assessments reveal that the D. claytoni mandible has posterior alveoli larger than anterior; flat mandibular body low in height; alveoli of p4 larger than m1; and a unique devinophocine combination of incisors (I3/1) that differs from those in the extant subfamilies Cystophorinae (I2/1), Monachinae (I2/2) and Phocinae (I3/2).","PeriodicalId":206426,"journal":{"name":"Vestnik Zoologii","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116503332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
