In article reports a new find of Pleurocladia lacustris in Ukraine. The species grew in the brackish-water Dnieper Estuary (depth 0.2 m, salinity of estuary water was 4.68‰, temperature – 23 °С, pH – 7.9) P. lacustris is a filamentous benthic species, the cells of which are not calcified here, as in freshwater conditions, but are covered with a slimy sheath. It was found in fouling of bushes of green algae Cladophora glomerata (Linnaeus) Kützing and Ulva flexuosa Wulfen, as well as blue-green (Calothrix C.Agardh ex Bornet & Flahault and Oscillatoria sp.) on a concrete slab in July 2020. The thickets of Potamogeton perfoliatus L., Ruppia maritima L., and Stuckenia pectinata (L.) Börner predominated in the coastal area of the estuary. Color illustrations of the vegetative and generative organs of P. lacustris are presented, its diagnostic macroscopic and microscopic characteristics are shown, which turned out to be somewhat larger than the data of the determinants. The ecological characteristics of the algae habitat meet the known requirements. This rare species is known in about 50 localities in Europe, North America, Australia and Africa. In many countries P. lacustris is considered an endangered species and is included in the protected red lists.

Abstract The paper presents the first record of a Chara connivens (Characeae) stand from Fuerteventura (Canary Islands, Spain). The species was previously recorded only on Tenerife and Lanzarote, mostly in marine and artificial habitats. Physicochemical parameters of water and morphological features of the thalli and plant community were analyzed. General habitat requirements of C. connivens populations located in Europe, North Africa, and South-West Asia were reviewed. The newly described stand was located in a natural rock crevice that was part of a riverbed in El Barranco de las Peñitas (Penitas Canyon). This habitat was unshaded and filled with brackish water. C. connivens co-occurred with Cladophora glomerata and Ruppia maritima. Our report on the presence of C. connivens in the Spanish territory of the Atlantic Ocean is the first in almost 40 years. The distribution of C. connivens and its plant associations on the Canary Archipelago are poorly explored, which is why this topic requires further research.

The study is concerned with the study of natural and landscape conditions of the territory of the Nature Reserve "Medobory", and its historical significance in formation of the biotic diversity of Western Ukraine. It focuses on the research into the territory and formation of the Nature Reserve "Medobory", which covers over 9 000 ha in the central Tovtry. Moreover, the work highlights the ongoing studies of zoobiota in the area, and points out its significance for preserving the regional fauna (by the end of 2019 the following species were recorded: 1 species of freshwater sponge, 79 species of molluscum, 32 species of centipedes, 2170 species of insects, 15 species of fish, 11 species of amphibians, 7 species of reptiles, 197 species of birds, 55 species of mammals). The study also provides a detailed analysis of international lists of threatened species valid for the territory of Ukraine, and the species from the Red Book of Ukraine (the 3rd edition); as a result it identifies certain species to be under protection, such as 41 species of mammals, 187 species of birds, 18 species of amphibian and reptiles, 4 species of fish, 30 species of arthopods, 1 species of molluscum. Altogether, there are 281 species in the international lists of endangered species, which makes 11 % of the reliably ascertained fauna variety of the conservation area (2566 species). Except for the arthopods, which are scarcely represented in the international lists, there are more than 63 % of the traced representatives of fauna vertebrates under protection, according to the international lists of endangered species (251 species out of 396 known ones). For many of the animal species the natural forest stand of Medobory is a refugium, where they survived the ice age, and in some of the localities certain rare relict species have survived into the present time. On the territory of the Nature Reserve Medobory the following animal species enlisted internationally have been registered: IUCN Red List - 18 species, the European Red Lists of species - 28 species, the Bern Convention – 256 species, the Bonn Convention – 102 species,the Bern Convention – 256 species, the Washington Convention – 37 species. 83 animal species of the Reserve and the surrounding territory call for protection since they are listed in the Red Book of Ukraine.

Osmoderma cristinae Sparacio, 1994 is an endemic beetle of Sicily (Coleoptera: Cetoniidae). It is a saproxylic species and has a very important role in the forest ecosystems. It is included in multiple national and international “Red Lists" as Endangered species (Audisio et al. 2014, Cálix et al. 2018). At the larval stages O. cristinae participes in the degradation of “dead wood” in old trees, in their cavities, and in downed logs. In this work, the larval morphology of O. cristinae is described.

The paper is devoted to alien fish species that have appeared in coastal waters of the Black Sea near Crimea for the past 50 years. The fish fauna of the Black Sea mainly comprises species that represent the Ponto-Caspian and Atlantic-Mediterranean faunal complexes. According to the generalised literature data, 158 fish species of 107 genera of 60 families have been recorded in the Black Sea since the publication of K. F. Kessler’s work (Kessler 1877), all of them representing the Atlantic-Mediterranean complex. In waters of Crimea, 116 species of 86 genera of 51 families have been recorded for the same period. A full checklist of fishes of this complex is presented indicating 31 alien species that have appeared since the 1970s and which belong to 27 genera and 16 families. In waters of Crimea, alien fishes make up 26.5 % of all species, 31.0 % of all genera, and 31.4 % of all families of the Atlantic-Medirranean complex. According to the level of their occurrence in marine waters of Crimea, all recently introduced species are grouped into three categories: regular, sporadic, and casual. Their brief characterisics are given, including synonymy, representation in the fish collection of the NMNH NASU, brief description, distribution, and vector of introduction. It was found that benthic species predominate among introduced fishes that occur regularly in waters of Crimea (12 species, or 80.0 %), while bentho-pelagic and pelagic species are less represented (6.7 % and 13.3 %, respectively). Pelagic and bentho-pelagic species prevail (50.0 % and 37.5 %, respectively) among fishes that occur sporadically. Bentho-pelagic species predominate (57.1 %) among fishes that occur casually. It was discovered that among the 31 alien fishes recorded in the Black Sea waters of Crimea for the past 50 years predominate those that have appeared here due to the natural process of mediterranisation (22 species, 71.0 %). It was imposibble to determine the vector of introduction of 4 species (12.9 %). The appearance of 5 species, which represent 16.1 % of all alien species, is related to anthropogenic factors. It can be also concluded that benthic species predominate among the alien fishes (14 species, or 45.2 %), while bentho-pelagic (9 species) and pelagic (8 species) fishes make up 29.0 % and 25.8 %, respectively. Of the 31 introduced fishes, 10 (32.2 %) have naturalised and acclimatised in marine waters of Crimea and have founded independent breeding populations. Among them, representatives of the family Gobiidae notably prevail, followed by the taxonomically close family Oxudercidae, whereas one species belongs to the family Blenniidae. The so-iuy mullet, which is the only representative of the pelagic ecological group, was introduced intentionally.

Asteraceae is one of the most abundant families of the Brazilian flora, and it stands out on Brazilian red lists due to the large number of endangered and data-deficient species, since it is difficult to define a conservation status for the latter. A comparative analysis of red lists of the Brazilian flora focused on the Asteraceae is important, so we can assess the true degree of threat to which these plants are subjected faced with increasing environmental degradation. Our analysis compared red lists, and pointed out the most threatened species or data-deficient areas, species and genera. The study was based on the first and the current Official List of Endangered Species of the Brazilian Flora, and the Brazilian Flora Red List of Fundação Biodiversitas. Species were organized according to the endangered and data-deficient IUCN categories. Endangered species were also classified according to threat category. The highest numbers of threatened species were observed in the Cerrado, in the southeastern region, and in the state of Minas Gerais, as well as in the genera Lychnophora Mart., Vernonia Schreb., and Richterago Kuntze. The genera Aspilia Thouars, Baccharis L., Calea L., Eupatorium L., Mikania Willd., Piptocarpha R.Br., and Senecio L. have the greatest number of data-deficient species. Since the current Official List does not make clear its threat criteria, the Red List of Fundação Biodiversitas best portrays the situation of endangered Asteraceae species; thus, this analysis provides important information for projects aimed at the conservation of threatened and data-deficient species.

Twenty-one species of water plants are found in the Avvakumovka River estuary and fourteen species - in the Olga River estuary in 3 surveys conducted in May, July, and September of 2012. Zostera marina dominates in the external estuary of both rivers in any season, whereas Potamogeton spp. and Ruppia maritima are the most abundant in some local areas of the Avvakumovka external estuary and Zostera japonica - in some local shallow areas of the Olga external estuary (where it forms perennial settlements). Chaetomorpha linum is the subdominant species in the Olga external estuary. In the Avvakumovka internal estuary, Cladophora glomerata and Z. marina are the dominants in May, Z. marina - in July, and Z. marina and Potamogeton spp. - in September, but any bottom vegetation is absent in the Olga internal estuary. From May to September of 2012, the summary biomass of water vegetation in both estuaries increased in 5 times: from 0.3 to 1.5 thousand tons.
