W przyrodzie istnieje cała gama organizmów, podobnych do porostów, składających się z dwóch lub większej liczby komponentów, które tworzą odrębną jednostkę. Należą do nich m.in. plazińce Symsagittifera roscoffensis, których ciało wypełniają glony Tetraselmis convolutae, czy największy z małży - przydacznia olbrzymia, która żywi się głównie dzięki symbiotycznym glonom Zooxanthella. Tego typu jednostki to swego rodzaju „niedokończone" gatunki, powstające w wyniku współpracy odrębnych form życia.

In nature, there is a whole range of organisms, like lichens, consisting of two or more components which form a separate unit. These include among others flatworms Symsagittifera roscoffensis whose body is filled with algae Tetraselmis convolutae, or the largest living bivalve mollusk - the giant clam, which feeds mainly due to symbiotic algae Zooxanthella. This type of unit is a kind of "unfinished" species, resulting from the cooperation of separate forms of life.

Two new species of the genus Vojnovskytes Fedorowski, 2009, namely V. marcinowskii and V. arcuatus, and a new genus, Vojnimitor, based on the new species V. proiectus, all from Mississippian strata of northern Spain, are described. Vojnovskytes variabilis (Vojnovsky-Krieger, 1934), the type species for the genus from the lowermost Viséan strata of southern Urals, also is discussed and illustrated. Characters displayed by the taxa mentioned permit introduction of a new family Vojnovskytesidae.

Struktury wapienne wytwarzane przez koralowce są podstawą do powstawania unikatowego ekosystemu, znanego jako rafa koralowa. Koralowce żyją w obligatoryjnej symbiozie z glonami. Spełniają one niezwykle ważne usługi ekosystemowe, wycenione na 6 bln funtów rocznie. Różne aspekty ludzkiej działalności są dzisiaj przyczyną ich ginięcia. Około połowy raf koralowych wykazuje silne i bardzo silne oddziaływanie. Konieczne są zdecydowane działania prawne i edukacyjne w ich obronie.

Calcium structures secreted by corals are the basis for the formation of the unique ecosystem known as a coral reef. Corals live in obligatory symbiosis with algae. They fulfill extremely important ecosystem services valued at 6 trillion pounds a year. Various aspects of human activity today are the cause of their disappearance. Approximately half of the coral reefs exhibit strong and very strong impacts. It is necessary to take decisive legal and educational actions in their defense.

Bashkirian Rugosa (Anthozoa) from the Donets Basin (Ukraine). Part 12. Concluding considerations

EN

A detailed analysis of the upper Viséan, Serpukhovian and Bashkirian Rugosa of the Donets Basin confirms their Mississippian/Pennsylvanian turnover during the Eumorphoceras / Homalophyllites-Hudsonoceras Zone, as postulated earlier (Fedorowski 1981a). The deterioration of rugose corals, globally diverse in time and space in the late Viséan and Serpukhovian, has resulted in the patchy distribution of survivors and newcomers, present in the Bashkirian. Difficulties in inter-basinal communication and the isolation of some sites have resulted in a different content of Bashkirian Rugosa in particular patches, with only rare genera in common. New data has made it possible to document the appearance of the first late Carboniferous genera in the Donets Basin as early as the lower Voznessenkian Horizon (= lower Chokierian Substage), i.e., close to the beginning of the Bashkirian Stage. The two stages of diversification, established in the Bashkirian rugose corals of the Donets Basin, cannot find their counterparts elsewhere. A palaeogeographic overview of the most important sites of diversified rugose corals documents the need to re-examine many taxa, which should be based on complete specimen studies. This and the precise placement of taxa in the modern stratigraphy must be done in order to make rugose corals globally comparable. Simple repetitions of names, commonly used in general summaries, is strongly misleading in both stratigraphic and palaeogeographic reconstructions.

Bashkirian Rugosa (Anthozoa) from the Donets Basin (Ukraine). Part 11. The Family Pentaphyllidae Schindewolf, 1942 and considerations on the Suborder Tachylasmatina Fedorowski, 1973

Inconsistency in the approach to the corals included by different authors in the families Tachylasmatidae Grabau, 1928 and Pentaphyllidae Schindewolf, 1942 are discussed in the context of their relationship vs homeomorphy to the Family Plerophyllidae Koker, 1924. Following Schindewolf (1942), the pentaphylloid or cryptophylloid early ontogeny, typical of the former two families, is contrasted with the zaphrentoid ontogeny typical of the latter family. Comprehensive analysis proves the independent taxonomic position of the Suborder Tachylasmatina Fedorowski, 1973. The taxa described herein support this idea. The relationship of the two families: Tachylasmatidae and Pentaphyllidae within the framework of this suborder are suggested. A new genus left in open nomenclature (represented by a single specimen) and three new species, Pentaphyllum sp. nov. 1, ? Pentaphyllum sp. nov. 2 and Gen. et sp. nov. 1 are described from lower Bashkirian deposits.
