Abstract

On the basis of the distinctly biplicate and carinate leaves in the distal portion Grimmia lawiana J.H. Willis, the only continental Antarctic endemic moss species, is transferred to the genus Coscinodon Spreng. and the new combination C. lawianus (J.H. Willis) Ochyra is proposed. The species is described and illustrated, its affinities are discussed and its geographical distribution in the Antarctic is mapped. Grimmia reflexidens Müll. Hal., a southern South American endemic species from Chile , is briefly assessed and this species is also shifted to Coscinodon as C. reflexidens (Müll. Hal.) Ochyra, comb. nov. A key to all species of the genus Coscinodon is presented. Guembelia longirostris (Hook.) Ochyra et Żarnowiec is reported for the first time from the Antarctic on the basis of a specimen collected from the Nordenskjöld Coast on the eastern coast of the Antarctic Peninsula.

Abstract

Schistidium cupulare (Müll. Hal.) Ochyra, an obscure and poorly known species originally described from Îles Kerguelen as Grimmia cupularis Müll. Hal. and subsequently reported from a single station in the Antarctic, is re-assessed taxonomically. It is considered to be a distinct species of sect. Conferta, closely related to S. amblyophyllum (Müll. Hal.) Ochyra et Hertel, from which it differs in its distal- and mid-leaf areolation of short, isodiametric, quadrate to shortly rectangular cells; stouter costa, 50–75 μm wide in the distal and median part, semi-terete to subrectangular in cross-section and prominently convex on the dorsal surface, (2–)3-stratose above, 3(–4)-stratose below; leaf margins regularly 2–3-stratose in 1–3 rows of cells forming fleshy, bulging limbidia; presence of a distinct central strand; and finely roughened to nearly smooth peristome teeth. S. celatum (Cardot) B.G. Bell from South Georgia and Tierra del Fuego is considered to be conspecific with S. cupulare. Some details of the type specimens of both species are illustrated. The geographical range of S. cupulare is evaluated and it is considered to be an amphiatlantic subantarctic species. A new record of the species from Livingston Island in the Antarctic is provided and a key to species of Schistidium in Antarctica is given.

Abstract

Nematodes occurring in the Antarctic bony fishes are reviewed, and keys based on morphological features are presented. Five valid species: Ascarophis nototheniae Johnston et Mawson, 1945; Cystidicola beatriceinsleyae (Holloway et Klewer, 1969); Dichelyne fraseri (Baylis, 1929); Hysterothylacium aduncum (Rudolphi, 1802); Paranisakiopsis weddelliensis Rocka, 2002, and one unnamed form, Capillaria (Procapillaria) sp., have been reported from the Antarctic teleosts. Also, larval anisakids, in the adult stage parasites of marine mammals, birds and fishes, occur commonly in the Antarctic and Subantarctic bony fishes. They belong to Contracaecum spp., Anisakis spp., Pseudoterranova decipiens (Krabbe, 1878) and Hysterothylacium aduncum.

Abstract

The new rich collection of fossil fish remains obtained during the Polish Spitsbergen Expedition of 1998 includes many isolated shark teeth, mostly of the genera Lissodus, Hybodus and Acrodus. The shark microfossils from the Hornsund area (South Spitsbergen) described here and the analysis of the histology of Lissodus teeth contribute to a better understanding of the previously described Early Triassic fish fauna from that region (Birkenmajer and Jerzmańska 1979). There is the evidence for coexistence of two types of histology within a single taxon what closes the discussion considering ortho- and osteodentine as a taxonomic factor.

Abstract

Palaeomagnetic investigation of the Upper Carboniferous clastic Hyrnefjellet Formation from opposite limbs of the Hyrnefjellet Anticline in southern Spitsbergen (Svalbard Archipelago) uncovered two components of NRM. Direction C1 (D = 224.6°; I = –27.9°; κ = 22.40; α95% = 5.6°) is of prefolding origin and most probably of near-primary origin. High Tb spectra above 575°C indicate hematite as the carrier of C1. Acquisition of the C1 component may be related to an early diagenetic crystallization of hematite, not excluding a detrital origin of the NRM. A paleopole calculated for the C1 component (F = 23.3°N; L= 147.7°E) falls into the Late Devonian–Early Carboniferous sector of APWP for Baltica. This result suggests that Svalbard remained in the present day orientation with respect to Baltica since the Carboniferous time. A second component with intermediate unblocking temperatures, determined in the Hyrnefjellet Formation deposits, is labelled C2. Its mean orientation for in situ position is D = 11.2°; I = 69.2° (κ = 44.05; α95% = 6.3°), thus being similar to Late Mesozoic directions for Baltica. After 100% tectonic correction for tilting of anticline limbs and axis, the C2 component orientation is D = 265.7°; I = 59.7°, thus being distant from any directions for Baltica. Detailed analysis suggest that the C2 component is most probably of synfolding origin, and it was formed during the Tertiary Alpine Tectonic Event.

Instructions for authors

Instructions for authors

The quarterly Polish Polar Research invites original scientific papers dealing with all aspects of polar research. The journal aims to provide a forum for publication of high-quality research papers, which are of international interest.

Articles must be written in English. Authors are requested to have their manuscript read by a person fluent in English before submission. They should not be longer than 30 typescript pages, including tables, figures and references. However, upon request, longer manuscripts may be considered for publication. All papers are peer-reviewed. With a submitted manuscript, authors should provide their names, affiliations, ORCID number and e-mail addresses of at least three suggested reviewers.

Submission of the manuscript should be supported with a declaration that the work described has not been published previously nor is under consideration by another journal.

For text submission, Word file format is preferred. The text should be prepared in single-column double-spaced format and 25 mm margins. Consult the current issue of the journal for layout and conventions. Figures and tables should be prepared as separate files. Line art images should be scanned and saved as bitmap (black and white) images at a resolution of 600–1200 dpi and tightly cropped. Computer versions of the photographs should be saved in TIFF format of at least 400 dpi (non-interpolated). Maximal publication size of illustrations is 126×196 mm. Authors must make sure that graphics are clearly readable at this size. ‘Hairline’ line width must not be used. All chart axes need to be labeled in full. For labeling sub-graphics in a single figure, capital letters placed in the upper left corner are preferred. Bold letters should not be used in tables (including headers), except to highlight a significant value/information.

A limited number of color reproductions in print is free of charge. Color artwork in PDF is free of charge.

Title should be concise, informative and no longer than 15 words. Abstract should have no more than 250 words. The authors are requested to supply up to 5 keywords, different than words used in the title. The references should be arranged alphabetically and chronologically. Journal names should not be abbreviated. Please, ensure that every reference cited in the text is also present in the reference list and vice versa.
Responsibility for the accuracy of bibliographic citations lies entirely with the authors. The inline references to published papers should consist of the surname of the author(s) followed by the year of publication. More than two authors should be cited with the first author’s surname, followed by et al. (Dingle et al. 1998) but in full in the References.
