A comprehensive checklist of the Tuscan woody flora providing sub-regional details is presented. This checklist comprises 412 taxa, of which 264 are native and 148 are non-native. Nine taxa new for the region were found, and eleven taxa were excluded from the regional flora. The native taxa belong to 109 genera and 53 families. Rosaceae is the family richest in taxa, with Rosa being the genus with the highest number of species. On the provincial level, the province of Grosseto is the province with the highest number of native taxa, followed by the provinces of Lucca and Florence. The lowest number of taxa was documented in the provinces of Pistoia and Prato. With regard to the non-native woody flora, the highest number of non-native taxa can be found in the province of Livorno, whereas the lowest number occurs in the provinces of Arezzo and Siena. At regional level, 9% of non-native taxa are invasive, 45% naturalized and 46% casual. Asia and North America are the most common native ranges of those taxa. After an extensive herbarium study, the taxonomy and distribution of Acer opalus, Cornus sanguinea, Juniperus deltoides, Oreoherzogia alpina, Pyrus communis, Quercus crenata, Salix elaeagnos, and Sorbus aria are discussed in more detail.

Thirteen genera are recognized in the family Venturiaceae (order Pleosporales, Loculoascomycetidae) in temperate North America. Eighty entities are included. Ten of these are new to science: Venturia fagi, V. pruni, V. canadensis, V. alaskensis, Xenomeris abietis, Antennularia oxydendri, A. alpina var. major, A. variisetosa, A, latispora, and A. ledi. Sixteen are new combinations: Venturia syringae (H. Syd.), V. rhamni (Bonar), V. weiriana (Petrak), V. juncaginearum (Lasch), Stigmatea pulchella (Cke. & Peck), Coleroa sporoboli (Greene), C. plantaginis (Ell.), Gibbera vaccinicola (Dearn. & House), G. cercocarpi (Ell. & Ev.), G. distegiae (Tracy & Earle), G. gaultheriae (Ell. & Ev.), Antennularia maculosa (Ell.), A. curviseta (Peck), A. fimiseda (Mout.), A. grossulariae (Auersw. & Fleischh.), A. vancouverensis (Dearn.). The new name Venturia minuta is proposed to replace the invalid V. microspora Nüesch and Venturia acerina Plakidas ex Barr is validated with a Latin diagnosis. The genus Venturia is subdivided into two subgenera: Venturia, comprising sections Venturia,Phaeosphaerella (Karst.) stat. nov., Endostigme (H. Syd.) stat. nov., and subgenus Spilosticta (H. Syd.) stat. nov., comprising sections Spilosticta,Macula sect, nov., Coleroidea sect. nov. Coleroa contains the subgenera Coleroa and Hormotheca (Bon.) stat. nov. Gibbera is divided into Gibbera and Venturioides subg. nov., and Antennularia into subgenera Antennularia,Capnoda subg. nov., Gibberoidea subg. nov., and Protoventuria (Berl. & Sacc.) stat. nov. A number of species which have been described in Venturia or other genera of the Venturiaceae are excluded from the family. Disposition of these taxa is made, including the new combinations Wentiomyces fimbriatus (Dearn. & House) comb. nov. and Nematostoma occidentalis (Ell. & Ev.) comb. nov.

The spermatozoa of 13 species belonging to seven different genera of the branchiobdellidan families Cambarincolidae and Bdellodrilidae (Annelida: Clitellata) were examined and compared with previously described members of the family Branchiobdellidae. Based on an examination of the spermatozoa in this relatively large number of species within the order, the variation in sperm morphology is now known to be much greater than was previously expected. Considerable variation was found in nearly all characters examined: the acrosome varied in length from 3 to 60 µm and in shape from straight for most of its length to twisted for its whole length. The nuclei also varied in size (from 4 to 22 µm) and in shape from straight to twisted. Four parallel but twisted mitochondria were present in all species examined, and differed only in length. The marginal fiber that coiled around the flagellum varied in size and pitch. By comparing the present data with those from other branchiobdellidans, we found that the apical concavity of the nucleus, the presence of the marginal fiber of the tail, and the absence of a true basal body with the central apparatus of the flagellum penetrating the midpiece mitochondria are the only characters common to all members of the Branchiobdellida. Sperm characters in this taxon are extremely variable, even within a single genus, thus making the definition of "a single" sperm model for the whole group highly problematic. However, the new data will be of significant value in future phylogenetic work.

Concepts of the family Hyolithidae Nicholson fide Fisher and the genera Hyolithes Eichwald and Orthotheca Novak have been expanded through time to encompass a variety of morphologically dissimilar shells. The Hyolithidae is here considered to include only those hyolithid species which have a rounded (convex) dorsum; slopes on the dorsum are inflated, and the venter may be flat or slightly inflated. Hyolithes encompasses species which possess a low dorsum and a prominent longitudinal sulcus along each edge of the dorsum; the ligula is short and the apertural rim is flared. The emended concept of Orthotheca includes only those species of orthothecid hyoliths which have a subtriangular transverse outline and longitudinal lirae covering the shell on both dorsum and venter.Eighteen species of Hyolithes and one species of Orthotheca from the Appalachian region and Western Interior were reexamined in light of more modern taxonomic concepts and standards of quality for type material. Reexamination of type specimens of H. similis Walcott from the Lower Cambrian of Newfoundland, H. whitei Resser from the Lower Cambrian of Nevada, H. billingsi Walcott from the Lower Cambrian of Nevada, H. gallatinensis Resser from the Upper Cambrian of Wyoming, and H. partitus Resser from the Middle Cambrian of Alabama indicates that none of these species represents Hyolithes. Hyolithes similis is here included under the new genus Similotheca, in the new family Similothecidae. Hyolithes whitei is designated as the type species of the new genus Nevadotheca, to which H. billingsi may also belong. Hyolithes gallatinensis is referred to Burithes Missarzhevsky with question, and H. partitus may represent Joachimilites Marek. The type or types of H. attenuatus Walcott, H. cecrops Walcott, H. comptus Howell, H. cowanensis Resser, H. curticei Resser, H. idahoensis Resser, H. prolixus Resser, H. resseri Howell, H. shaleri Walcott, H. terranovicus Walcott, and H. wanneri Resser and Howell lack shells and/or other taxonomically important features such as a complete aperture, rendering the diagnoses of these species incomplete. Their names should only be used for the type specimens until better preserved topotypes become available for study. Morphology of the types of H.? corrugatus Walcott and “Orthotheca” sola Resser does not support placement in the Hyolitha; the affinities of these species are uncertain.

Review of recently collected material of Eohiodon from North America suggests that there are two valid species, E. rosei (Hussakof) and E. woodroffi Wilson. Eohiodon falcatus Grande is identical to E. woodruffi in known skeletal features and nearly all meristic features and is treated as a junior synonym of the latter. The fossil genus Eohiodon Cavender differs from Hiodon Lesueur, which is known from both fossil and extant species, in numerous meristic and osteological features. The caudal skeleton in Eohiodon is nearly identical to that in Hiodon.The traditionally accepted Notopteroidei, containing Lycopteridae, Hiodontidae, and Notopteridae, is a polypheletic group. The Asian fossil family Lycopteridae is not more closely related to Hiodontidae than it is to other taxa in the Osteoglossomorpha, but is sister to all other Osteoglossomorpha. The Hiodontiformes sensu stricto, including only the family Hiodontidae, is the sister-group of the Osteoglossiformes. This family is not more closely related to notopterids than to other taxa in Osteoglossiformes. The Notopteridae are most closely related to the Mormyroidea; together they and the fossil family Ostariostomidae constitute the sister-group of the Osteoglossoidei.Fossil records of Hiodontiformes sensu stricto and Notopteroidei indicate a widespread pre-Neogene biogeographic range of these freshwater teleosts, suggesting that extinction must have been involved in the Cenozoic evolution of these two osteoglossomorph sublineages.

Podisma (Latr.) is a particularly interesting genus of Melanopli, since it is the only one of that immense group that occurs in the Old World, where, indeed, it is represented by considerably more described species than it is in North America. It is also of interest from its distinctly boreal and alpine distribution, being almost peculiar to high latitudes or altitudes. It is a circumpolar genus, inhabiting the mountains and boreal parts of Europe, Asia and North America, a larger number of species having been described from Europe than elsewhere.

The Bromide Formation of the Middle Ordovician Simpson Group of Oklahoma contains one of the oldest diverse bryozoan faunas in North America. The early divergence of many trepostome clades is revealed in these rocks. Three trepostome bryozoan species belonging to family Halloporidae are described from this fauna. Discriminant analysis is used to define the following halloporid species: Diplotrypa schindeli n. sp., Tarphophragma karklinsi n. sp., and Tarphophragma macrostoma (Loeblich). Preliminary cladistic analysis indicates that the family Halloporidae was already a distinct lineage by the Middle Ordovician. This suggests that by this time, many of the major trepostome clades were already established.

Ranaviruses are large double stranded DNA viruses from the family Iridoviridae. They are globally distributed and are currently known to affect fish, reptiles and amphibians. In North America, ranaviruses are also widely distributed, and cause frequent morbidity and mortality events in both wild and cultured populations. This is a synopsys of the North American content of the 4th International Symposium on Ranaviruses held in May 2017 in Budapest, Hungary.

Although Egyptians are generally known to be a non-migrating people closely tied to their land, the late 1950s and 1960s saw waves of Egyptians leaving their homeland for Europe, North America and Australia. Migration to Australia was limited prior to this period. In 1933, there were only 500 Egyptian-born people recorded as living in Australia. This number jumped to 8,000 in 1954 and 22,000 by 1966. Today there are around 34,000 Egyptian-born people in Australia and approximately 16,500 of them (nearly 50 per cent) live in Sydney.Around three-quarters of Egyptian migrants settled in Australia before 1976. However, there were substantial numbers of 'recent arrivals' (accounting for almost 15 per cent of this group) in 1986–91. Most of these later migrants came under the family reunion scheme. Generally the Egyptian community is a highly educated one, with qualification levels that exceed those of the average Australian. Today many Egyptian migrants living in Sydney belong to the professional and managerial classes.

This article discusses the museum system of modern Kazakhstan and offers, for the first time ever, a classification and typology of the country’s museums.In recent years in independent Kazakhstan, on the basis of the Soviet system, a modern museum network has been formed which currently lists 250 museums. Among them are 17 national-level museums, 54 at the regional level, 73 at the provincial level, 103 branches of regional- and district-level museums and four private museums.The purpose of this article is to analyse the museum system of modern Kazakhstan and develop a classification and typology of the country’s museums.In the course of the study, conducted in 2017–2018, data was collected on the activities of museums at the national, regional and district levels over the past seven years. From the results of this investigation, the museums of Kazakhstan were systematized according to the subject or topic of the museum (e.g. history, art, scientific), its affiliation (national, regional district), and by size, measured by number of employees.
