Download or read book Ross Sea Ecology written by F.M. Faranda and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 594 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Antarctic represents the last of the world's still unexplored continents. Since 1985, Italy has sent 10 expeditions to this region, three of those have been exclusively devoted to research on the marine ecology of the Ross Sea region. This volume presents a global picture of this research. It includes contributions on water mass characteristics, particulate organic matter and nutrient utilization, and physiological aspects of primary production. Further topics are zooplankton, krill and top predator interactions in relation to physical and biological parameters, ecological features of coastal fish communities and the spatio-temporal variability of benthic biocenoses.
Book Synopsis Ecological Studies in the Antarctic Sea Ice Zone by : Wolf E. Arntz
Download or read book Ecological Studies in the Antarctic Sea Ice Zone written by Wolf E. Arntz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten years ago Polar Biology published the book, Weddell Sea Ecology, containing the European "Polarstern" study EPOS in the Weddell Sea and Peninsula waters 1988/89. In certain respects, the present collection of papers, first published in Polar Biology in 2001, is a follow-up as it combines papers partly based on three "Polarstern" expeditions to the same region. Further articles relate to both land-based and shipborne studies, again primarily in the Atlantic sector and around the Antarctic Peninsula. The SCAR programme, "Ecology of the Antarctic Sea Ice Zone" (EASIZ), served as an umbrella for a truly international cooperation. Although funding came exclusively from national sources, 40% of the scientists on board "Polarstern" were foreigners. Out of the 35 papers of the present volume not less than 14 papers have multinational authorship. The scope of EASIZ is wider ilian the Southern Ocean Studies in JGOFS and GLOBEC. The Contents reflect emphasis on the study of benthos, which hitherto had not received the necessary attention in the attempt to understand key questions of evolution and zoogeography of fauna from the Southern Hemisphere. The information collected under EASIZ enhanced greatly our recognition of the rather high biodiversity of ilie Antarctic shelf benthos. In order to extend these studies to ilie deeper continental slopes and the deep sea, "Polarstern" is presently on her way for ilie first international survey of deep-sea benthos in the Atlantic sector of ilie Southern Ocean.
Book Synopsis Entomology of Antarctica by : J. Linsley Gressitt
Download or read book Entomology of Antarctica written by J. Linsley Gressitt and published by American Geophysical Union. This book was released on 1967 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 10. The existence of insects, mites, and their relatives on the antarctic continent is of great interest to many. These terrestrial arthropods may be said to be the dominant land animals in the absence of land vertebrates and many major groups of invertebrates. They are important in the simple food cycles which involve most segments of the land flora and microorganisms, and they play a part in soil formation. Thus a knowledge of their ecology is essential to the understanding of various biotic balances and processes. That several species live in the area of 85°S latitude in the face of harsh climatic factors is of great concern to the ecologist and the physiologist—therin lie many unanswered questions for future research.

Book Synopsis Systematics and Diversity of Annelids by : Maria Capa
Download or read book Systematics and Diversity of Annelids written by Maria Capa and published by MDPI. This book was released on 2021-08-18 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this Special Issue, we address the state of the art of the systematics of the main annelid groups and the improvements in the diversity they hold, with special emphasis on the latest discoveries in well-studied areas, expeditions to unsurveyed areas or environments, or the use of novel techniques that allow for the improvement of biodiversity knowledge. We are hoping that this Special Issue will provide a platform facilitating a review of current knowledge on the subject, identifying current research problems, as well as indicating directions and research trends for the future.

Book Synopsis Recent Antarctic and Subantarctic Brachiopods by : Merrill W. Foster
Download or read book Recent Antarctic and Subantarctic Brachiopods written by Merrill W. Foster and published by American Geophysical Union. This book was released on 1974 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 21. The Recent brachiopod faunas from southernmost South America, Antarctica, and the Subantarctic consisting of 21 genera and 37 species are described from new material. New taxa include the genera Manithyris and Bathynanus. Also new are 11 species: Compsothyris ballenyi, Hispanirhynchia? chiliensis, Manithyris rossi, Liothyrella multiporosa, Liothyrella scotti, Bathynanus tenuicostatus, Eucalathis macrorhynchus, Amphithyris hallettensis, Dallina eltanini, Fallax antarcticus, and Magellania? spinosa. Factor analysis was used to study relationships among morphological characters and environmental parameters. In Liothyrella, negative associations were found between beak height and water depth. The size of the pedicle opening within this genus is associated with the width of the hinge plate and the loop; apparently, these associations are related to increased dorsal adjustor muscle size with increased pedicle size. Similar relationships are found in the terebratellids, although here all of the characters are also negatively associated with water depth. Characters negatively associated with water depth may relate to the differing current strength at various depths. Puncta density is positively correlated with water temperature. Examples of brachiopod variation are discussed. Synonyms have resulted from former failure to study large samples and to appreciate the extent of brachiopod variation. A priori valuation of certain characters as being specific is unwarranted, since sibling species may be more similar than different subspecies of the same species. Many Recent and fossil brachiopod genera are too narrow in definition owing to oversplitting or to a narrow conception of monophyly. I advocate somewhat broader and more practical genera for obtaining the maximal information value from such taxa. Brachiopods, contrary to popular belief, are an abundant and viable group in the southern hemisphere faunas. Most brachiopods in the Ross Sea appear to have definite niches and habitats but may overlap geographically where population densities are low. Brachiopods here can be divided roughly into a slope and a shelf assemblage. The greatest species diversity occurs at the seaward edge of the Ross Sea shelf, interpreted as an ecotone effect where two different water types meet. Only South America and Antarctica appear to have or have had direct communication between some elements of their brachiopod faunas. Other similarities between separate southern continents are related to retention of common pre-Cenozoic elements or to chance dispersal of larvae across barriers. Events related to cooling during the late Pliocene or Pleistocene caused reduction of puncta density, shell thickness, and spiculation in the Recent fauna and apparently influenced the present species structure, at least in Liothyrella uva, Gyrothyris mawsoni, and Macandrevia.
