Available in PDF, EPUB and Kindle. Book excerpt: Diatoms are an important element of many polar marine microbial communities and particularly abundant in Antarctic lakes. However, few comprehensive studies, such as the study presented in this volume are available on Antarctic communities. The diatom floras encountered in surface sediment samples from 33 lakes of the Vestfold Hills, Antarctica are presented. 67 distinct diatom species were identified in these sediments. They include cosmopolitan, Southern Ocean, endemic Antarctic and new diatoms. Each species encountered is described and illustrated; autecological information on the species is included where possible. Epilimnion water chemistry of the lakes sampled was determined to investigate their influence on diatom distribution. The studied lakes span a very large range of salinities from 0.5 to 165 permil. The authors show that salinity seems to have a strong influence on the observed diatom taxa.

Available in PDF, EPUB and Kindle. Book excerpt: This book examines diatoms in polar marine environments, and is subdivided into three parts. The first section covers the environments and their communities, the second section is a taxonomic guide to most of the important genera and species found in the polar marine phytoplankton and in sea-ice communities, and the third section is a bibliography.

Download or read book Diatom Taxonomy and Ecology written by Bart van de Vijver and published by . This book was released on 2018-01-03 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Beiheft of Nova Hedwigia features twenty contributions by more than 40 authors, representing the entire range of Prof. Le Cohu's work and interests. Topics of the contributions range from purely taxonomic papers to articles dealing with diatom biodiversity, ecology, paleoecology and biogeography. The papers apply both traditional and novel techniques. They describe more than 20 new species (high quality SEM images) and three new genera and several taxa are revised. Geographically, the contributions to this volume span a a wide region, from the part of France, where Ren� le Cohu started his research, to the sub-Antarctic Kerguelen Islands from where he has described a great number of species. This Beiheft is dedicated to Prof. Dr. Ren� Le Cohu on the occasion of his 80th birthday, in recognition of his life-long scientific work on the taxonomy and ecology of algae, and diatoms in particular. It addresses phycologists and other researchers working on diatoms and algae.

This book was released on 1986 with total page 1190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The history of Cenozoic ice sheets in Antarctica has been interpreted largely from deep-sea data. A new approach, which provides a more direct evaluation of Antarctic ice history, involves the examination of reworked diatom assemblages in the Sirius Formation tillites. These diatoms originate from subglacial sedimentary basins in East Antarctica and indicate periods of relative warmth, ice sheet retreat and the repeated presence of marine seaways/embayments in the continental interior during the Cenozoic. Antarctic ice-minima conditions are indicated by marine diatoms and other microfossils recovered from Sirius Formation localities spread over 1300 km in the Transantarctic Mountains. The modern distribution and temperature limits of several Pliocene diatoms recovered from the Sirius Formation indicate marine water as warm as 2̃°-5°C in the antarctic interior to at least 85°S latitude. Geologic time intervals not represented by microfossils in the Sirius Formation may indicate times of extensive ice development. The glacial history these microfossils suggest is substantiated by comparison to global sea-level and benthic foraminiferal oxygen isotope data. A detailed analysis of isotopic and eustatic records, together with Sirius Formation data, indicate ice-minima conditions and relative warmth, with marine seaways across Antarctica, during the Pliocene (5̃ to 2.5 Ma), middle Miocene (1̃7 to 14 Ma), late Oligocene/early Miocene (2̃7 to 23 Ma) and during much of the early Oligocene and remaining Paleogene. Glaciations are indicated during the late Oligocene (3̃1 to 27 Ma), late Miocene (1̃0 to 5 Ma) and Pleistocene (2̃.5 Ma to present). Bottom-water/ice-shelf events, recognized in a detailed comparison of eustatic and benthic oxygen isotopic data, preceed late Oligocene and late Miocene ice-sheet growth by 5̃ million years. Analysis of diatom biostratigraphy and paleoecology from numerous in situ Oligocene through Pliocene sedimentary outcrops and drill-holes around the Antarctic periphery have aided dating of the above reworked microfossils and have documented glacial and marine fluctuations in more uniform environments. Of particular significance is the recovery of upper Oligocene glacial-marine sediments in the MSSTS-1 drill-hole, the oldest known from Antarctica.

Available in PDF, EPUB and Kindle. Book excerpt: The present monograph is a detailed taxonomical description of the diatom flora of the Laptev Sea (Arctic Ocean). The Laptev Sea is one of the most important epicontinental seas of the Arctic, marked by large freshwater inputs. Approximately 60% of the diatoms found in the Laptev Sea are freshwater species which originally occur in lakes and rivers of the Siberian hinterland. These diatoms are transported into the Laptev Sea by five large streams.
