Abstract:
In 2022 the taxonomic and zoogeographic composition of the macrozoobenthos of six lowland lakes of the Russian Altai: Aya, Beloe, Kireevo, Kolyvanskoe, Koksha and Svetloye was investigated. In the studied lakes 156 species of zoobenthos from 9 classes of invertebrates were identified. The largest number of species is characteristic of the insect class. Chironomids and oligochaetes dominated in terms of frequency of occurrence in the lakes. Of the oligochaetes, the family Tubificidae (68%) was more frequently observed. Tubificidae (68%), chironomids — subfamilies Chironominae (91%) and Tanypodinae (66%). The maximum species diversity of zoobenthos was observed in lakes Beloe (81 species) and Koksha (76 species), the least number of species was found in lakes Aya (41 species) and Kireevo (52 species). Lakes Beloe — Kireevo — Kolyvanskoe and Koksha — Svetloye are the most similar in composition of benthic invertebrates. The most original was the taxonomic composition of the deepest lake Aya. According to the taxonomic composition of the fauna of bottom invertebrates, most lakes (Aya, Beloe, Kireevo, Kolyvanskoe) were closer to plain water bodies, two lakes (Koksha, Svetloe) combined features of both plain and mountain lakes. Zoogeographic analysis of the fauna of benthic invertebrates of foothill lakes revealed 12 types of distribution. Holarctic (39%), Palaearctic (23%) and Western Palaearctic species (21%) were predominant in the lake fauna. Comparative analysis of the fauna of the identified homotopic and heterotopic species showed that the most extensive areas are found only among homotopic primary aquatic archaic taxa. Zoogeographic analysis of the studied lakes indicate their proximity to the border of the Western and Eastern Palearctic.

Abstract. The Omma-Manganji fauna of Japan signifies a time during the late Pliocene and Pleistocene when arctic-subarctic species migrated far south of their present geographic range in response to oceanographic changes. Omma-Manganji deposits exposed on Hokkaido, northern Honshu, and Sado Islands yielded about 224 species of marine Ostracoda. At least 26 are circumpolar species known previously from Arctic seas off the British Isles, eastern North America, Scandinavia and Europe, comprising between 14 and 47% of the ostracod assemblage in eight of ten formations studied. The 26 circumpolar species and 21 other western Pacific cryophilic species are illustrated and their distribution in Japanese deposits is discussed.

Abstract:
Water striders (Hemiptera, Gerromorpha) are common inhabitants of aquatic habitats throughout the world. More than 150 species representing five families have colonised the marine environment, chiefly coastal areas of tropical seas in habitats with a strong tidal influence. The Australian fauna of marine water striders is particularly diverse and species-rich, comprising about 30 species. The present paper deals with the marine Haloveliinae (Veliidae) of Australia, New Caledonia and southern New Guinea. They are classified in two genera, Xenobates Esaki and Halovelia Bergroth. Xenobates mangrove, ovatus, major and spinoides (Queensland), X. lansburyi and chinai (Northern Territory), and X. caudatus (southern Papua New Guinea) are described as new. X. myorensis (Lansbury), X. angulanus (Polhemus) and X. loyaltiensis (China) comb. nov. are redescribed. Descriptive notes are presented for the five species of Halovelia recorded from Australia. Keys to adults of all species are provided and their distributions mapped. Finally, we discuss the zoogeography and ecology of the marine Haloveliinae of Australia.

Abstract:
<p><strong>Abstract.</strong> Awareness of the importance of ever-growing environmental problems implies the need to study the relationship of biological, social, anthropogenic systems with nature. The environment of life is a complex multicomponent system and each of the components is a factor determining the state of the others, since all of them are interconnected with each other. Indicators of the state of ecological-geographical systems are organisms that create a biological environment, which requires the acquisition of relevant knowledge, including knowledge related to the field of zoology and zoogeography.</p><p>The authors have developed two new zoogeographic maps with elements of ecology. The first is the “<i>Zoogeographic Map of Russia</i>”(1 : 25 000 000) in the forthcoming edition of the Geographical atlas for secondary school teachers. The second is the “<i>Animal world of the Russian Arctic Region (mammals)</i>”(1 : 12 000 000) – a scientific map for the electronic edition of the National Atlas of the Arctic. Further, the principles of design and methods for creating these maps are revealed.</p><p>Approaches to the design of the educational “<i>Zoogeographic Map of Russia</i>” are based on the analysis of work programs that follow the Federal State Educational Standard. According to the requirements of these documents, pupils should know the animal population of Russia, the animal world of the native land, the natural zones of the country, altitudinal zoning, they should be able to give examples of the most indicative representatives of the natural zones, explain the species diversity of the animal world, know its taxonomy, and measures for protection. The guidelines for map design are proposed in accordance with these requirements and implemented in the author's original image (fig. 1).</p><p>The thematic content of the map is based on the scientific systematics of the animal world. It covers the fauna of land, seas and sea coasts, and freshwater reservoirs. The map has a significant novelty and greater informative capacity in comparison with similar publications and a purpose surpassing the educational application. Selection of vertebrate animals includes not only mammals and birds, but also amphibians, cyclostomes, fishes and cetaceans. The image of the continental fauna is linked with the conditions of its habitat—natural zones, their parts, geographic areas with the identification of endemic and animals listed in the Red Book of Russia. The author's original is placed on two pages, of which map legend occupies a separate page in landscape format (fig. 2). It includes almost complete description of animals of all natural zones.</p><p>The concept of the scientific map “<i>Animal world of the Russian Arctic Region (mammals)</i>” means defining the position of mammals in the organic world system, with animals being hierarchically differentiated from kingdom to species – the basic unit of life forms system and the basic taxonomic element of mapping. Unlike most zoogeographical maps, displaying only land animals, the Arctic marine mammals are also the target of research and mapping. Further, the display of the relation between animals and their habitat landscape types (plain and mountain) is introduced into the map concept. The matrix form of the legend shown in the figure 3 with the map tile is subject to coverage of the variety of land animals. Both land animals and marine animals listed in the Red Data Book of the Russian Federation and regional Red Data Books of Russia highlighted on the map. The total of 85 mammal species of the unique Arctic Regions is listed on the map.</p><p>The results of performed mapping studies are essential for evolution of knowledge about the nature of Russia and its regions and for biodiversity conservation of vertebrate animals.</p>

Full text
Abstract:
The early origin and evolutionary radiation of graptolites (Hemichordata:Pterobranchia) is a story told almost entirely in the fossil record, but for four extant species of the genus Rhabdopleura Allman, 1869. Here we report the discovery of a fifth species, Rhabdopleura recondita, sp. nov., at a depth range of 2–70m from the Adriatic and Ionian Seas, always associated with bryozoans in coralligenous habitats. This is the first pterobranch record in Italian waters, and the second in the Mediterranean Sea. The new species is characterised by: (1) tubaria with smooth creeping tubes adherent to the inside of empty bryozoan zooecia; (2) erect outer tubes with a graptolite, fusellar-like organisation; and (3) zooids that extend from a black stolon, which is free from the creeping tube. Each of the paired feeding arms has two rows of tentacles that do not extend to the arm tip. The distal ends of the arms, the collar and the cephalic shield are replete with black granules. Phylogenetic analyses of individual and concatenated gene sequences of mitochondrial 16S rDNA and nuclear 18S rDNA support the validity of R. recondita as a new species. Finally, we discuss the global biogeographic and habitat distributions of the extant Rhabdopleura representatives. http://zoobank.org/urn:lsid:zoobank.org:pub:82C6A51E-F8F4-44AF-AD8F-16873BE80D03

Abstract:
A literature survey was conducted to investigate the host and geographical distribution patterns of three <i>Corynosoma</i> species (Acanthocephala: Polymorphidae), <i>viz. C. magdaleni</i>, <i>C. semerme</i> and <i>C. strumosum</i>. All three species appear to be restricted to the Northern Hemisphere. Occurrence records of <i>C. magdaleni</i> are limited to the Northern Atlantic coasts, while <i>C. semerme</i> has a circumpolar distribution. The geographical range of <i>Corynosoma strumosum</i> encompasses the distributions of the other two species, but also extends into warmer southern regions. Some <i>Corynosoma</i> populations are living with their definitive hosts in very isolated locations, such as in the brackish Baltic Sea or different freshwater lakes (e.g. Lake Saimaa). All three species have a heteroxenous life cycle, comprising a peracaridan intermediate host, a fish paratenic host and a mammalian definitive host. Occasionally, an acanthocephalan may enter an accidental host, from which it is unable to complete its life cycle. The host records reported here are categorised by type, <i>i.e.</i> intermediate, paratenic, definitive or accidental. While most of the definitive hosts are shared amongst the three <i>Corynosoma</i> species, <i>C. strumosum</i> showed the broadest range of paratenic hosts, which reflects its more extensive geographical distribution. One aim of this study and extensive literature summary is to guide future sampling efforts and therewith contribute to throw more light on the on-going species and morphotype discussion for this interesting parasite species.

VICENTE, CARLOS SAN. "Geographical and bathymetric distribution of mysids (Crustacea: Mysida) in the seas of the Iberian Peninsula." Zootaxa 4244, no. 2 (2017): 151. http://dx.doi.org/10.11646/zootaxa.4244.2.1.

Full text
Abstract:
The zoogeographic distribution of mysid species occurring in the diverse seas of the Iberian Peninsula and neighbouring areas is analysed. For each species, bathymetric range and localities data are reported. A total of 129 mysid species belonging to 50 genera have been recorded, representing 11% of all known world extant species and the 28% of genera. Littoral mysids are the most diverse group (64 species) followed by the outer-self to upper-bathyal slope with 54 known species. Patterns of bathymetric zonation are characterized by four bathymetric discontinuities at about 100, 500, 1300 and 2700 m. Each geographical region is characterized by the presence of a mixture of exclusive and shared species composition. Mysid distributions suggest that an important grouping of species present in the Iberian fauna share a common origin. Based on the analysis of published records and reported species, it is suggested that there is a high probability of the discovery of new species of Mysida in the water surrounding the Iberian Peninsula.

Full text
Abstract:
Comprehensive information on Antarctic macrobenthic community structure has been publicly available since the 1960s. It stems from trawl, dredge, grab, and corer samples as well as from direct and camera observations (Table 1–2). The quality of this information varies considerably; it consists of pure descriptions, figures for presence (absence) and abundance of some key taxa or proxies for such parameters, e.g. sea-floor cover. Some data sets even cover a defined and complete proportion of the macrobenthos with further analyses on diversity and zoogeography. As a consequence the acquisition of data from approximately 90 different campaigns assembled here was not standardised. Nevertheless, it was possible to classify this broad variety of known macrobenthic assemblages to the best of expert knowledge (Gutt 2007; Fig. 1). This overview does not replace statistically sound community and diversity analyses. However, it shows from where which kind of information is available and it acts as an example of the feasibility and power of such data collections. The data set provides unique georeferenced biological basic information for the planning of future coordinated research activities, e.g. under the umbrella of the biology program “Antarctic Thresholds - Ecosystem Resilience and Adaptation” (AnT-ERA) of the Scientific Committee on Antarctic Research (SCAR) and especially for actual conservation issues, e.g. the planning of Marine Protected Areas (MPAs) by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).

Abstract:
In Poland, there are 4 species of the liypodendron genus: T lineaium Oliv., T domestkum L., T signature Fakir. and 7: laeve Egg. Trypodendron laeve is the leastknown of this group. Many factors had influence on the state of research on this species, including taxonomic aspects. Taking into account the unsatisfactory state of knowledge regarding the prevalence of T iaeve in Poland, as well as scarce information on the morphology of this species, research was undertaken to I) document the presence, including new sites, of T laeve in Poland and define, if possible, the habitat and trophic conditions that may affect its occurrence, as well as II) determinate suitability of biometric and genetic methods for correct identification of t laeve against the background of other ambrosia beetle species. Research on the occurrence of T laeve in Poland, was carried out on 143 areas located throughout the country, representing various environmental conditions, primarily such as species composition of tree stands, terrain, altitude (from 16 to 929 meters above sea level) and their location in relation to zoogeographic regions. The research material was obtained mainly using various types of traps for catching ambrosia beetles baited with pheromone. Only in a few cases when attacking the wood of trees, the imagines of ambrosia beetles were obtained without luring agents. The research was conducted in 2007-2016. From the insect individuals identified on the grounds of morphological traits as T lineatum, T laeve, T domesticum and T signatum, originating from selected locations in Poland, 3-11 specimens were collected, for which genetic analyses were performed based on the COI gene fragments obtained by PCR. The research included tests for following paramcter: s sequence similarity, phylogenetic, evolutionary divergence and genetic. structure. As a result of research on the occurrence of ambrosia beetles in Poland, a total of 44207 individuals belonging to four species were collected: T lineatutn, 7: laeve, T domesticum and T signatum, whose share was respectively: 49.2%, 31.4%; 19.1% and 0.3%. In Poland, 1: laeve's imagines were found in 124 out of 143 examined sites. The presence of L reeve has been documented for the first time in 14 zoogeographic regions. This species was commonly found on study areas located from 118 to 929 m above sea level. In Poland the tree species attacked by T Mate include Pinus sylvestris L. and Picea abies (L) H. Karst. In Poland, T laeve as a host plant prefers sylvestris and reaches the highest population densities in the stands of this species. The work presents the exact morphological characteristics of T laeve and indicates the most important features that distinguish it from the other Trypodendrun spp. occurring in Poland. It has also been shown that the best results in the determination of species of the liypodendron genus, regardless of their sex, can be obtained using phylogenetic analysis based on a fragment of the COI gene.
