Tintinnid ciliates (Ciliophora, Tintinnida) of the Black Sea and the Sea of Azov

Abstract

В монографии обобщены оригинальные результаты исследований и литературные данные об инфузориях отряда Tintinnida, отмеченных в Чёрном и Азовском морях. Книга содержит общую характеристику отряда, информацию о морфологии 51 вида из 20 родов и 10 семейств, многолетней и сезонной динамике раковинных инфузорий в Севастопольской бухте Чёрного моря и особенностях распространения тинтиннид. В Севастопольской бухте были выделены группа круглогодичных видов, а также летне-осенний и осенне-весенний видовые комплексы. На основании данных по распределению температуры и солёности в Чёрном и Азовском морях выделены четыре видовых комплекса тинтиннид: 1) видовой комплекс побережья Кавказа, Крыма и северо-западной части Чёрного моря; 2) комплекс побережья румынии, болгарии и Азовского моря; 3) глубоководный видовой комплекс; 4) комплекс Синопской бухты. Английские резюме всех глав, в том числе диагнозы всех зарегистрированных в Чёрном и Азовском морях видов, включены в приложение. монография предназначена для гидробиологов, зоологов, фаунистов, таксономистов, а также для преподавателей и студентов высших учебных заведений. The results of author's investigations and literary data on ciliates of the order Tintinnida observed in the Black Sea and the Sea of Azov are summarized in the monograph. Book contains the general characteristic of order, information on morphology of 51 species from 20 genera of 10 families, their longterm and seasonal dynamics in Sevastopol Bay of the Black Sea and peculiarities of tintinnid distribution. English summaries of all chapters, including diagnoses of all species recorded in the Black and Azov Seas are included in the Appendix. The monograph dedicated for hydrobiologists, zoologists, faunal researchers and taxonomists as for lecturers and students of higher education schools.

Biogeography of marine tintinnid ciliates (Ciliophora, Tintinnida): a Scale-Dependent Model

“…Tintinnids also demonstrated a latitudinal gradient of species richness, which has been linked to average sea surface temperature, thought to reflect water column characteristics. Thus, in agree with Dolan & Pierce's (2013) opinion there are large-scale spatial and temporal patterns in the distribution of Tintinnida, and this corresponds to the MEM hypothesis (Gavrilova & Dovgal, 2018). Gavrilova & Dovgal (2018) analyzed the impact of water salinity and temperature on distribution of marine tintinnid species.…”

Gavrilova & Dovgal (2018) analyzed the impact of water salinity and temperature on distribution of marine tintinnid species. As a result, 80 species were classified into six ecological groups (eurythermal; stenothermal-thermophilic; stenothermal-cold-loving; stenohaline, inhabiting in mixohaline waters; stenohaline, inhabiting in euhaline waters).…”

First Record of the Alien Tintinnid Ciliate Rhizodomus tagatzi Strelkow and Wirketis 1950 in the Adriatic Sea

“…The tintinnid Rhizodomus tagatzi is common in ecosystems with high trophic levels and stable water column, such as the Thau Lagoon [12] and the lagoon of Urbino in the northern Mediterranean [11], the Damietta Harbour in Egypt [14], the coast of Hurghada in the Red Sea [28], Lake Faro in Sicily (central Mediterranean) [4], northern Lebanon in the eastern Mediterranean [29], Izmir Bay in the Aegean Sea [15], the Gulf of Gemlik in the Sea of Marmara [16], and Sevastopol Bay in the Black Sea [18,30]. For a more detailed overview of the geographic distribution of R. tagatzi outside the Mediterranean Sea, the reader can refer to the work of Dolan and Pierce [31] and Saccà and Giufrè [4].…”

“…On the other hand, differences in the appearance of the main horn and lateral branches, as well as in the agglutination of the lorica, were observed most frequently. In contrast to the specimens from the Neretva River estuary, the aboral horns are much more robust in R. tagatzi from Peter Great Bay in Russia [6], Jiaozhou Bay in China [51], and Sevastopol Bay [18], and in T. corniger from the Gulf of Gemlik in Turkish coastal waters [16]. A considerably longer caudal horn (more than one-third of the total lorica length) was found in T. corniger from the Strait of Hormoz and waters of the United Arab Emirates [10], while a completely hyaline lorica was found in R. tagatzi from Lake Faro in Sicily [52].…”

“…Water 2023, 15, 1821 2 of 14 as T. nudicauda in the eastern Mediterranean [17] and as Rhizodomus tagatzi in the Black Sea [18]. According to the European Alien Species Information Network (EASIN) [19,20] tintinnid Rhizodomus tagatzi Strelkow and Wirketis 1950 is classified as an alien species introduced into the eastern Mediterranean Sea in 2007 [15].…”
