Abstract

Skeletal remains of penguins from the Eocene La Meseta Formation (Seymour Island, Antarctica) constitute the only extensive fossil record of Antarctic Sphenisciformes. No articulated skeletons are known, and almost all fossils occur as single isolated elements. Most of the named species are based on tarsometatarsi (for which the taxonomy was revised in 2002). Here, 694 bones (from the Polish collection) other than tarsometatarsi are reviewed, and allocated to species. They confirm previous conclusions and suggest that ten species grouped in six genera are a minimal reliable estimate of the Eocene Antarctic penguin diversity. The species are: Anthropornis grandis, A. nordenskjoeldi, Archaeospheniscus wimani, Delphinornis arctowskii, D. gracilis, D. larseni, Marambiornis exilis, Mesetaornis polaris, Palaeeudyptes gunnari and P. klekowskii. Moreover, diagnoses of four genera (Anthropornis, Archaeospheniscus, Delphinornis and Palaeeudyptes) and two species (P. gunnari and P. klekowskii) are supplemented with additional, non-tarsometatarsal features. Four species of the smallest penguins from the La Meseta Formation (D. arctowskii, D. gracilis, M. exilis and M. polaris) seem to be the youngest taxa within the studied assemblage - their remains come exclusively from the uppermost unit of the formation. All ten recognized species may have co-existed in the Antarctic Peninsula region during the Late Eocene epoch.

Abstract

The mathematical model that described the relationship between cell-count decay and storage time in fixed bacterioplankton samples from three Antarctic lakes of differing trophic status was determined after a one-year experiment. Bacterial density was estimated by epifluorescence microscopy. Cell count data fitted a negative exponential model in all three cases (p < 0.00001). However, the slopes of their curves were significantly different (p < 0.01), as well as the percentage of bacterial loss after a period of two months. This fact might be related to the limnological characteristics of the water bodies, though the individual genetic variability of their bacterioplankton should not be left aside. Original bacterial numbers in the samples could also be a reason of the differences observed in the pattern of decay in cell counts. Thus, applying a general decay function to any sample and assuming the idea that freshwater bacterioplankton samples can be stored for a two month-period before the bacterial counts decay, can lead to an erroneous estimation of bacterial numbers with direct consequences in ecological investigations.

Abstract

This paper includes a check-list of Recent Svalbard marine ostracods based on published sources and on diploma theses as well as some new studies. This is the first study of this group of crustaceans from Hornsund. A total of 41 species belonging to 12 families were collected at 55 sampling stations from dredged sediments. Seven species are reported for the first time from the Svalbard Archipelago. Polycope orbicularis Sars is the most abundant species in the present fauna. Species compositions of Hornsund and the Liefdefjorden are seen to have the highest similarity (S = 50.6).

Abstract

The fusulinid foraminifers of Schellwienia arctica (Schellwien, 1908) have been investigated from Polakkfjellet Mt., south Spitsbergen, and used as biostratigraphic marker for the latest Carboniferous earliest Permian strata of the Treskelodden Formation. A series of thin sections enable to investigate the internal structure and growth pattern of individual specimens. The observed variation of growth suggests dynamic environmental conditions at the investigated location and most likely over one-year long life span of this foraminifer.

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.
