Opis:
Populus is a genus that contains numerous taxa that are often difficult to identify. They are grouped into six sections which are mainly based on the differences in the structure of flowers and leaves. Nevertheless, other features are also of great importance in identifying individual sections. In this paper, individual sections are characterized. Two subsections within the Populus section (syn. Leuce Duby) are distinguished, due to the clear differences between white poplars and aspens. The sections are as follows: sect. 1. Abaso Eckenw. (mexican poplar), sect. 2. Turanga Bunge (arid and tropical poplars), sect. 3. Leucoides Spach (bigleaf poplars), sect. 4. Aigeiros Duby (cottonwoods and black poplar), sect. 5. Tacamahaca Spach (balsam poplars), sect. 6. Populus, with two subsections: 6a. Populus (white poplars) and 6b. Trepidae (Dode) Tamm (aspens).

Opis:
Lieberkuehnia wageneri Claparède et Lachmann, 1859, a poorly known freshwater foraminiferan, was re-discovered after 38 years in a moss sample from an oak-hornbeam forest in Malé Karpaty Mts. (Western Slovakia). The species was taxonomically revised, re-described using light microscopical observations, and its occurrence and ecology were reviewed. Its locomotive form is typical with membranous and flexible ovoid test having a single terminal aperture from which a broad pseudopodial network emerges on a pseudopodial peduncle. Additional data and details are described, illustrated and discussed. Lieberkuehnia wageneri is known from various freshwater, soil and marine habitats in Western and Middle Europe, suggesting a high ecological tolerance and wide distribution. It is hoped that the observations reported in this paper will aid the identification of this species based on the locomotive morphology at the light microscopical level.

Opis:
Thecamoeba aesculea n. sp. was isolated and described from the surface of the bark of Aesculus hippocastanum and from terrestrial mosses growing on it. This amoeba is superficially similar to Thecamoeba sphaeronucleolus, but comparison of the newly isolated strain with the photographs and video records of the type strain of this species reveals differences which show that the two strains do not belong to the same morphospecies. The data obtained indicate the necessity of further comparative studies on the diversity of thecamoebian ‘morphospecies’ to outline clearer borders between them.

Opis:
The oligotrichid ciliate Strombidium coronatum (Leegaard, 1915) Kahl, 1932 is redescribed from plankton samples taken in the Irish Sea, using live observation, protargol impregnation, and scanning electron microscopy. The species is characterized by a conspicuous, uniquelly shaped peristome, which is flat and roughly triangular and extends in the sagittal plane. The Irish Sea specimens measure ~ 45 × 25 µm in vivo and ~ 40 × 24 µm after protargol impregnation. The girdle kinety is equatorial, ostensibly continuous, and composed of ~ 100 dikinetids. The ventral kinety extends longitudinally on the posterior fifth of the cell and is composed of about five dikinetids. The adoral zone of membranelles is widely open and composed of ~ 18 collar and ~ 12 buccal membranelles; the collar portion is disconnected from the buccal portion. The shape and orientation of the opisthe’s adoral zone of membranelles are apparently extraordinary, i.e., the membranelles form an inverted L-shaped stripe extending longitudinally in the elongated posterior cell portion of dividers.

Opis:
Cochliopodium actinophorum (Auerbach, 1856) is one of the oldest and most frequently mentioned species of the genus, yet the structure of scales comprising tectum of these amoebae has never been described, and the strain previously used to re-define this species based on light microscopic characters was lost. A new strain identified as C. actinophorum using light microscopy was isolated recently, and molecular sequence data of this strain were published, yet without any morphological data. Here, the results of light and electron microscopic study of this strain are presented that confirm its identification as C. actinophorum and allow a proposal of a new diagnosis of this species thus linking morphology, scale ultrastructure and available gene sequence data. The newly isolated strain deposited with CCAP (accession number 1537/10) is designated as a neotype.

Opis:
Juniperus communis is represented in Poland by two subspecies, the typical J. communis subsp. communis and J. communis subsp. alpina. The former taxon is an upright shrub or small tree and occurs in the lowlands, up to the montane vegetation zone in the mountains. The letter is a prostrate shrub that grows in the high mountains, specifically in the subalpine vegetation zone. Juniperus communis subsp. communis was once one of very frequent components of the woody flora in Central Europe. In Poland, it thrived on sandy, nutrient-poor soils, serving as a primary component in plant communities classified under the Koelerio glaucae-Corynephoretea canescentis class. It was also found in pine forests of the Vaccinio-Piceetea and in oak woods, mainly in Potentillo albae-Quercetum. Last decades however, it has become increasingly rare and, in some areas, has disappeared completely. The regression of J. communis subsp. communis is evident not only in its decline on sandy, nutrient-poor soils but also in a significant reduction in occurrence frequency within forest communities across most of the country. Its high frequency is now retained only in northeastern Poland.

The morphology and infraciliature of three marine cyrtophorid ciliates, Dysteria lanceolata Claparède and Lachmann, 1859, Lynchella nordica Jankowski, 1968 and Chlamydonyx paucidentatus Deroux, 1976, collected from the coastal waters of Qingdao, China, were investigated using live observations and the protargol impregnation method. D. lanceolata was oval in body outline, about 65 × 45 μm in vivo, with a subcaudally positioned podite, six to seven right kineties, two or three frontoventral kineties, and two ventral contractile vacuoles. The improved diagnosis for L. nordica and a key to all known Lynchella species are supplied. The rediscovery of C. paucidentatus enables us to accept its taxonomic identification (e.g., separation from a morphologically similar species Trochilioides recta). The genus Trochilioides Deroux, nov. gen., which was a nomen nudum according to ICZN (1999), is re-established.

Opis:
Poszukiwanie skutecznych metod wyboru informacji wynika z obserwowanego obecnie nadmiaru danych. W artykule jest opisana metoda GQM (Goal, Question, Metric) wykorzystywana w informatyce między innymi do budowy wielowymiarowej funkcji jakości oprogramowania. Opiera się ona na jawnym zdefiniowaniu celu wyboru danych z uwzględnieniem punktu widzenia użytkownika. W artykule wykazano, że metoda ta może być również wykorzystywana do poszukiwania i wyboru danych z dedykowanych zbiorów informacji dziedzinowych. Metoda pozwala na ograniczenie zbioru danych w ściśle określony sposób z uwzględnieniem cech dziedziny, celu, w jakim dane będą wykorzystywane i konsekwencji wynikających z odrzucenia pozostałych danych. Metoda ta może być również stosowana do wyboru i budowy zorganizowanych w formie taksonomii zbiorów danych opisanych w języku naturalnym. Należy przypuszczać, że skuteczne metody wyboru danych będą w przyszłości powszechnie wykorzystywane w wyszukiwaniu i prezentacji informacji.
Considering the excess of available data, it is necessary to design effective methods of data selection. This paper presents an application of the GQM (Goal, Question, Metric) method in data selection and processing. The GQM method is typically used in software development to define and specify multidimensional software quality functions that assume explicit definition of data selection purpose depending on user or software developer requirements. In this paper, it is shown that the method may also be used to select appropriate data from different dedicated domain data sets. The method enables a user to narrow the set of selected data in a strictly specified manner considering the characteristic of a target domain, the purpose of data selection and consequences of potential data rejection. As shown in the paper, the method may be applied to select data from educational data sets, taxonomy-based literature sets and natural language description of object oriented structures.

Opis:
In December 2022. Parliament and the Council of the European Union adopted the Directive on Corporate Sustainability Reporting EU/2022/2464 . This directive is linked to a number of European Commission regulations enacted between 2019 and 2022, primarily concerning environmental and climate issues. The full implementation of the provisions of these new pieces of legislation into practice, due to their great complexity and voluminosity, appears to be a difficult process and one that requires considerable effort, not only organisational but also financial, from the companies covered. This study aims to present the objectives and goals of Directive EU/2022/2464 and its associated regulations, and to evaluate these legal acts. As a result of these discussion, it has been established that the newly introduced regulatory system for corporate sustainability information meets the current challenges facing the societies and economies of EU member states. The system is extremely complex in terms of the content of its provisions, which makes compliance with the established regulations appear to be a very difficult task. information. It can reduce the risk of investing in questionably sustainable assets or limit unfair competition from surrounding companies. A system of ‘taxonomies’ may also contribute to increasing the transparency of individual markets, which arguably has a positive impact on the cost of preparing investor projects. The introduction of a ‘taxonomy’ into the practice of companies involves an increase in the costs of data collection, processing and disclosure as required by this system. Linked to Directive EU/2022/2464, the ‘taxonomy’ system is one of the key tools for creating a common framework for sustainable investment activities and practices. This system can bring many benefits to investors. Indeed, it can effectively reduce greenwashing by standardising the disclosure of environmental sustainabilit information. It can reduce the risk of investing in questionably sustainable assets or limit unfair competition from surrounding companies. A system of ‘taxonomies’ may also contribute to increasing the transparency of individual markets, which arguably has a positive impact on the cost of preparing investor projects. The introduction of a ‘taxonomy’ into the practice of companies involves an increase in the costs of data collection, processing and disclosure as required by this system.

Psammophaga fuegiais a new monothalamid foraminifera discovered in surface sediment samples in the Beagle Channel, South America. The species is a member of the important, globally distributed genus Psammophaga, which has the ability to ingest and store mineral particles inside the cytoplasm. Its shape is ovoid to pyriform, the size varies from 250 to 600 µm in length and from 200 to 400 µm in width. Like other Psammophaga species P. fuegia has a single aperture. It was found in multiple samples across the Beagle Channel area at water depths of 4 to 220 meters and in environments as variable as fjords, the main channel, and the harbour of Puerto Williams (Chile). The occurrences of the new species in environmental DNA and RNA samples correspond well to its distribution inferred from the microscopic study.

Opis:
High accuracy of the results is very important task in any grouping problem (clustering). It determines effectiveness of the decisions based on them. Therefore in the literature there are proposed methods and solutions that main aim is to give more accurate results than traditional clustering algorithms (e.g. k-means or hierarchical methods). Examples of such solutions can be cluster ensembles or spectral clustering algorithms. A desirable quality of any clustering algorithm is also stability of the method with respect to small perturbations of data (e.g. data subsampling, small variations in the feature values) or the parameters of the algorithm (e.g. random initialization). Empirical results shown that cluster ensembles are more stable than traditional clustering algorithms. Here, we carry out an experimental study to compare stability of spectral clustering and cluster ensembles.

Opis:
We describe Diplophrys parva n. sp., a freshwater heterotroph, using fine structural and sequence evidence. Cells are small (L = 6.5 ± 0.08, W = 5.5 ± 0.06 µm; mean ± SE) enclosed by an envelope/theca of overlapping scales, slightly oval to elongated-oval with rounded ends, (1.0 × 0.5–0.7 µm), one to several intracellular refractive granules (~ 1.0–2.0 µm), smaller hyaline peripheral vacuoles, a nucleus with central nucleolus, tubulo-cristate mitochondria, and a prominent Golgi apparatus with multiple stacked saccules (~ 10). It is smaller than published sizes of Diplophrys archeri (~ 10–20 µm), modestly less than Diplophrys marina (~ 5–9 µm), and differs in scale size and morphology from D. marina. No cysts were observed. We transfer D. marina to a new genus Amphifila as it falls within a mo-lecular phylogenetic clade extremely distant from that including D. parva. Based on morphological and molecular phylogenetic evidence, Labyrinthulea are revised to include six new families, including Diplophryidae for Diplophrys and Amphifilidae containing Amphifila. The other new families have distinctive morphology: Oblongichytriidae and Aplanochytriidae are distinct clades on the rDNA tree, but Sorodiplophryidae and Althorniidae lack sequence data. Aplanochytriidae is in Labyrinthulida; the rest are in Thraustochytrida; Laby-rinthomyxa is excluded.

Opis:
This paper investigates the morphology and morphogenesis during binary fission of a Chinese population of Euplotes amieti Dragesco, 1970, a fresh water form which has previously not been well defined. This organism is morphologically very similar to the well-known Euplotes eurystomus but differs from the latter both in the number of dorsal kineties and the molecular data. According to the information obtained, it is characterized by a combination of features including nine frontoventral cirri, ca. 60 membranelles, 12–15 dorsal kineties, a macronucleus in the shape of the number 3, and a ‘double-eurystomus’ type of silverline system. Its morphogenesis proceeds broadly in the same pattern as in its congeners. In this study, the SSU rRNA gene was sequenced for the first time, and phylogenetic analyses indicated that it is closely related to the eurystomus-aediculatus-woodruffi- complex. Considering the extreme similarities in morphology between E. amieti and E.eurystomus, we believe that the four sequences (four isolates) under the name of Euplotes eurystomus (No. FR873716; FR873717; EF193250; AJ310491 deposited in GenBank) are very likely from misidentified material; that is, they represent different populations of Euplotes amieti.

The mutual comparison of isolated strains has extended the knowledge of morphological diversity within the genus Stenamoeba Smirnov, Nassonova, Chao et Cavalier-Smith, 2007. Molecular data obtained for these strains have complemented the phylogenetic tree that so far has contained only one nominal species within the single-genus Stenamoeba clade.
